Description

Rotary trigger mechanism, handle and locking device capable of being opened internally and externally

Technical Field

The invention relates to a locking and unlocking mechanism, in particular to a locking and unlocking mechanism applied to a vault door.

Background

Most of the existing vault door locking mechanisms adopt two sets of rotating wheel mechanisms for separating an inner door from an outer door (namely the front door and the rear door), and the operation switching mode of the inner door and the outer door is realized by a trigger handle (namely the disengagement handle), namely when the vault door enters from the outer door, the outer handle of the vault door is directly rotated, and at the moment, the inner handle of the vault door does not participate in the action of the mechanism; when the door leaves the inner door, the trigger switch needs to be operated first, and then the inner door is rotated to open the door. The scheme divides the unlocking of the inner door into two operation actions, particularly prolongs the operation time in a device mechanism with an escape and refuge mechanism, such as a vault door, and violates the conventional operation habit.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example one

As shown in fig. 1, 2 and 3, the present embodiment is a locking device which is opened inside and outside, is generally arranged on a vault door, and is used for locking and unlocking the vault door, and comprises a mounting plate 1, a gear 11, a lock pin member 2, a locking mechanism 3 and an inner door handle 5. The gear 11, the latch member 2, the lock mechanism 3 and the door inner handle 5 are provided on the mounting plate 1.

The locking pin member 2 is arranged on the mounting plate 1 by a translational sliding limiting mechanism 6, so that the locking pin member 2 can slide and translate on the mounting plate 1. In the present embodiment, the locking pin member 2 is a plate-shaped member, and those skilled in the art will understand that the locking pin member 2 may have other shapes such as a long strip. The locking pin member 2 can be extended out of the mounting plate 1 or retracted into the mounting plate 1 by sliding translation. The locking pin member 2 is used to connect a door latch of the vault door. When the locking device of the embodiment is installed on the vault door, when the locking pin member 2 extends out of the installation plate 1, the bolt on the vault door is driven to lock the vault door; when the locking pin member 2 retracts towards the mounting plate 1, the bolt on the vault door is driven to release the locking of the vault door. Or, when the locking pin member 2 retracts towards the mounting plate 1, the bolt on the vault door is driven to lock the vault door; when the locking pin member 2 extends out of the mounting plate 1, the bolt on the vault door is driven to release the locking of the vault door. That is, the latch member 2 has two states, corresponding to two states of the door latch, respectively: a closed state and an open state. The closed state of the vault door latch is the closed state of the lock pin member 2, and the open state of the vault door latch is the open state of the lock pin member 2. The closed state of the vault door latch is the locking state of the vault door, namely the vault door is locked and cannot be opened or closed.

The locking mechanism 3 serves to capture the locking pin member 2. The locking pin piece 2 is provided with a take-off hook 4. The jump hook 4 is used to hook the locking mechanism 3. The locking mechanism 3 is hooked through the take-off hook 4, so that when the locking mechanism 3 is locked at the position, the lock pin piece 2 is locked and slides and translates through the hooking of the take-off hook 4; the latch member 2 is capable of sliding translation when the locking mechanism 3 is unlocked in position. The jump hook 4 can be disconnected from the lock mechanism 3. When the jump hook 4 is disconnected from the lock mechanism 3, that is, the latch piece 2 is disconnected from the lock mechanism 3, whereby the latch piece 2 can be slidably translated regardless of whether the position of the lock mechanism 3 is locked. That is, the trip hook 4 is disconnected from the lock mechanism 3, meaning that the lock mechanism 3 unlocks the latch member 2.

The gear 11 and the inner door handle 5 are coaxially connected by a coupling 12. And is provided on the mounting plate 1 with its axis perpendicular to the plate surface of the mounting plate 1 so that the gear 11 can rotate about its axis. In this embodiment, the gear 11 and the coupling 12 are disposed on the mounting plate 1 through a bearing set 14. The gear 11 is fixedly connected with the coupling 12. The lock pin member 2 is provided with a rack 21 engaged with the gear 11, so that the lock pin member 2 can be driven by the gear 11 to slide and translate when the coupling 12 rotates. The two ends of the coupling 12 are respectively an outer end and an inner end, wherein the outer end of the coupling 12 is connected with the outer door handle, and the inner end is connected with the inner door handle 5. The door outer handle is a handle located outside the door when the locking device of the present invention is mounted on the door, and the door inner handle 5 is a handle located inside the door. Both the door outer handle and the door inner handle 5 can be rotated about the axial center of the coupling 12. The door outer handle, the gear 11 and the coupling 12 are fixedly connected, and when the door outer handle rotates, the coupling 12 drives the gear 11 to rotate.

In this embodiment, the latch member 2 is in an open state when retracting into the mounting plate 1, and the latch member 2 is in a closed state when extending out of the mounting plate 1. Thus, with reference to the opening direction indicated by the arrow F0 in fig. 3, when the gear wheel 11 rotates in the opening direction, the latch member 2 is brought to retract into the mounting plate 1, with reference to the arrows F1 and F2; when the gear 11 rotates in the reverse direction in the opening direction, the latch member 2 is driven to extend outward from the mounting plate 1.

The inner door handle 5 includes a handle portion 581 rotatable with respect to the gear 11. The gear 11, the coupling 12 and the door inner handle 5 constitute a rotation triggering mechanism 50. The rotation trigger mechanism 50 includes a first rotation portion, a second rotation portion, and a trigger portion. In the present embodiment, the gear 11 serves as a first rotating portion, and the handle portion 581 serves as a second rotating portion. The trigger part is connected with the first rotating part or the second rotating part and is used for triggering the take-off hook 4 so as to disconnect the take-off hook 4 from the locking mechanism 3. By rotating the trigger mechanism 50, the locking device of the present invention achieves mutual opening between the inside and the outside, specifically, at least the following functions are achieved:

when the handle portion 581 of the door inner handle 5 rotates in the opening direction, the handle portion 581 can drive the trigger portion to move along with the rotation of the handle portion 581, and then the trigger portion is moved to trigger the trip hook 4 to be disconnected from the locking mechanism 3, so that the locking of the locking mechanism 3 on the latch member 2 is released, and then the handle portion 581 continues to rotate in the opening direction, so as to drive the gear 11 to rotate in the opening direction, and further drive the latch member 2 to slide and translate, so that the latch member 2 is switched from the closed state to the open state.

In the above process, the rotation of the handle portion 581 is divided into two stages: the first stage is a disconnection unlocking stage, that is, the handle portion 581 is rotated from the initial state to the disconnection state of the trip hook 4 from the locking mechanism 3, and the second stage is a disconnection unlocking stage, that is, the trip hook 4 is disconnected from the locking mechanism 3 to drive the gear 11 to rotate until the latch member 2 moves to the unlocking state.

For the rotation triggering mechanism 50, in the disconnecting and unlocking stage, the initial position of the handle portion 581 is the second initial position of the second rotating portion, and the rotation to the disconnection of the jump hook 4 and the locking mechanism 3 is equivalent to the rotation of the second rotating portion to the triggering position angle, that is, the second rotating portion is rotated to the triggering position angle from the second initial angle; for the triggering part, the second rotating part is rotated to the triggering position angle from the second initial angle, and drives the triggering part to move from the first triggering position to the second triggering position. That is, the trigger has two positions: a first trigger position and a second trigger position. When the trigger part is at the second trigger position, the tripping hook 4 and the locking mechanism 3 are triggered to be disconnected; when the trigger part is at the first trigger position, the hooking of the take-off hook 4 and the locking mechanism 3 is not influenced, and the disconnection of the take-off hook 4 and the locking mechanism 3 is not triggered.

In the disconnection opening stage, the gear 11 rotates to the state that the latch member 2 moves to the open state, which is equivalent to the second rotating portion rotating to the second stop angle, and is also equivalent to the first rotating portion rotating from the first initial angle to the first stop angle, that is, when the second rotating portion is rotated from the trigger position angle to the second stop angle, the first rotating portion is driven to be rotated from the first initial angle to the first stop angle. The gear 11 as the first rotation part is at a first initial angle corresponding to the latch member 2 being in the closed state. The gear 11 as the first rotation portion is at the first stop angle corresponding to the latch member 2 being in the open state. The first rotating portion is rotated to a first stop angle from a first initial angle, that is, when the door outer handle is rotated in the opening direction, the gear 11 is driven to rotate in the opening direction by the coupling 12, and the latch member 2 is driven to slide and translate by the meshing action of the gear 11 and the rack 21, so that the latch member 2 is switched from the closed state to the open state.

In the above process, the following three necessary action relationships are also implicit:

one of the necessary operational relationships, the above-described procedure should not interfere with the operation of the locking device through the outside door handle. Specifically, when the lock mechanism 3 is rotated in the opening direction with the position unlocked, that is, when the gear 11 is rotated in the opening direction, the trigger portion remains at the same position and the trip hook 4 cannot be triggered, and the latch piece 2 is connected to the lock mechanism 3 via the trip hook 4. In the case of the rotational trigger mechanism 50, this corresponds to the case where the first rotating portion is rotated from the first initial angle to the first stop angle, and at this time, the trigger portion is held at the first trigger position. Obviously, in the case where the lock mechanism 3 is locked in position, the gear 11 cannot rotate in the opening direction, and the door outer handle cannot rotate.

In the second necessary operational relationship, in the disengagement/unlocking stage, it is considered that the gear 11 cannot rotate when the position of the lock mechanism 3 is locked, that is, the gear 11 as the first rotating portion is kept stationary in this stage.

In the third necessary action relationship, in the disconnecting and opening stage, in order to avoid the hooking of the take-off hook 4 and the locking mechanism 3, the trigger part is kept at the second trigger position, that is, the trigger part is always in a state of triggering the take-off hook 4 and the locking mechanism 3 to be disconnected.

In addition, in the present embodiment, the gear 11, the coupling 12 and the door inner handle 5 may preferably have the following four operational relationships:

in one preferable operational relationship, when the handle portion 581 of the second rotating portion is at the second stop angle and the door outer handle is reversely rotated in the opening direction, that is, when the gear 11 as the first rotating portion is rotated from the first stop angle to the first initial angle, the handle portion 581 as the second rotating portion can be rotated from the second stop angle to at least the trigger position angle. The term "at least" means that the second rotating portion is preferably brought back to the second initial angle.

In the second preferred operational relationship, the first elastic mechanism is connected to the second rotating portion, and when the handle portion 581 serving as the second rotating portion is located at the trigger position angle, the handle portion 581 serving as the second rotating portion can be returned from the trigger position angle to the second initial angle by the elastic force of the first elastic mechanism.

Preferably, in the third operational relationship, the second elastic mechanism is connected to the triggering portion, and the handle portion 581 as the second rotating portion can return from the second triggering position to the first triggering position by the elastic force of the second elastic mechanism at least when the handle portion is located at the second initial angle. The term "at least" used herein means that the triggering portion may return to the first triggering position when the second rotating portion is not at the second initial angle.

In the fourth preferred operational relationship, when the gear 11 as the first rotating unit is rotated from the first initial angle to the first stop angle, the handle 581 as the second rotating unit can be held at the second initial angle as much as possible.

With respect to the specific structure of the rotary trigger mechanism 50, two specific embodiments are given in the present specification: one is a rotary trigger mechanism implemented by a telescopic tongue mechanism, and the other is a rotary trigger mechanism implemented by a cam pin structure. For the two embodiments, reference is made to the detailed description of the specification that follows.

In this embodiment, there are two lock pin members 2, the two lock pin members 2 are arranged in central symmetry about the axis of the gear 11, and the two sides of the lock pin member 2 are in bilateral symmetry with the positions connected to the door bolt, so that the racks 21 on the two lock pin members 2 are opposite and parallel to each other, and the gear 11 is clamped between the two racks 21. When the shaft coupling 12 is rotated in the reverse direction of the opening direction, the two locking pin members 2 are respectively protruded to the outside of both sides of the mounting plate 1. When the coupling 12 is rotated in the opening direction, the two latch members 2 are retracted toward the center of the mounting plate 1, see arrows F1 and F2 in fig. 3. The opening direction is the direction indicated by the arrow F0 in fig. 3.

In the present embodiment, the translational sliding restricting mechanism 6 includes a kidney-shaped restricting hole 61 and a restricting bolt 62. The waist-shaped limiting holes 61 on the lock pin piece 2 are distributed in a multi-point manner, and the waist-shaped limiting holes 61 have the same specification and are parallel. The lock pin piece 2 is clamped on the mounting plate 1 through a limit bolt 62 penetrating through the waist-shaped limit hole 61, so that the lock pin piece 2 slides in a translation mode in the length direction of the waist-shaped limit hole 61, and the extending or retracting distance of the lock pin piece 2 is limited by the length of the waist-shaped limit hole 61. That is, the length of the waist-shaped stopper hole 61 determines the stroke of the lock pin member 2.

One of the two lock pin pieces 2 is provided with a take-off hook 4, and is connected with the locking mechanism 3 through the take-off hook 4, so that when the locking mechanism 3 is locked in position, the lock pin piece 2 is locked through the connection of the take-off hook 4. When the locking mechanism 3 is unlocked, the locking pin piece 2 can slide and translate on the mounting plate 1; when the locking mechanism 3 is locked in position, the latch member 2 is locked against movement, and the corresponding gear 11 and coupling 12 are correspondingly locked against rotation.

In this embodiment, the locking mechanism 3 is an alternative locking mechanism, and includes a balance rod 33, two locking members 31 and two locking devices 32. The capture member 31 is disposed on the mounting plate 1 by the translational slide limiting mechanism 6 such that the capture member 31 is capable of sliding translational movement on the mounting plate 1. The two locking pieces 31 are arranged in parallel and the sliding translation directions are parallel. Two ends of the balance pull rod 33 are respectively and movably connected with the two locking pieces 31 in a swinging way. The movable swinging connection here means that the end part of the balance pull rod 33 is connected with the pendulum shaft through a waist-shaped hole, so that the balance pull rod 33 can slide along the length direction of the waist-shaped hole relative to the pendulum shaft, that is, the pendulum shaft hole at the end part of the balance pull rod 33 is a waist-shaped hole. A hook column 331 for connecting the take-off hook 4 is arranged in the middle of the balance pull rod 33. The two detent devices 32 correspond to the two locking elements 31. In the present embodiment, the locking member 31 is a plate structure, but those skilled in the art will understand that the locking member may also be a block-shaped member or other structures.

The locking device 32 is disposed on the mounting plate 1 and is used for locking the corresponding locking member 31. The position-locking device 32 has a position-locking part, and when the position-locking part of the position-locking device 32 abuts against the corresponding position-locking member 31, the corresponding position-locking member 31 is locked and cannot slide and translate. In this embodiment, the locking device 32 is an electronic lock. The position-locking part of the position-locking device 32 is a bolt of the electronic lock. Those skilled in the art will appreciate that other configurations of the detent mechanism 32 are possible, such as a permanent magnet mechanism or a gravity hammer mechanism, for example.

The translational slide limiting mechanism 6 connected with the locking member 31 and the translational slide limiting mechanism 6 connected with the locking pin member 2 have the same structure, and the description is omitted.

In this embodiment, the locking member 31 has a locking position, when the locking member 31 is in the locking position, the engaging portion of the engaging device 32 can be abutted against the locking member 31, and when the locking member 31 is not in the locking position, the engaging portion of the engaging device 32 is abutted against the locking member 31 and cannot be abutted against the moving direction of the locking member 31. In short, the locking mechanism 3 can only be locked when the locking member 31 is in the locking position. In the embodiment, referring to fig. 16, the locking member 31 is provided with two parallel locking plates 313 on two sides. The catch plate 313 is parallel to the direction of translation of the lock catch 31. The detent device 32 is disposed laterally to the translational direction of the lock member 31. When the lock unit 31 is in the locked position, the detent portion of the detent device 32 can abut against the end 314 of the detent plate 313 in the moving direction. When the lock stopper 31 is not in the lock position, the side surface of the stopper plate 313 abuts against the stopper portion of the stopper device 32 and cannot abut against the end 314 of the stopper plate 313 in the moving direction, so that the position of the lock stopper 31 cannot be locked.

The jump hook 4 includes a hook plate 41 and a hook spring 42. One end of the hook plate 41 is provided on the latch member 2 through a swing shaft 43 so that the hook plate 41 can swing about the swing shaft 43 perpendicular to the plate surfaces of the mounting plate 1 and the latch member 2. Referring to fig. 4 and 5, the hook plate 41 is provided at an upper side thereof with a hook notch 411. The hook spring 42 is provided between the latch member 2 and the hook plate 41 and provides a tensile force to the hook plate 41. The pulling force of the hook spring 42 swings the hook plate 41 in the direction of the side with the hook notch 411, so that the hook notch 411 can be caught in the hook column 331, see the swinging direction indicated by the arrow F4 in fig. 4 and 5. When the hook 331 is caught in the hook notch 411, the latch member 2 is connected to the lock mechanism 3 via the kick-off hook 4. When the locking pin member 2 is connected to the locking mechanism 3, if the two locking members 31 are locked by the two locking devices 32, the two locking members 31 cannot slide and translate, the positions of the balance rod 33 and the hook column 331 are locked, accordingly, the locking pin member 2 connected to the jump hook 4 is locked and cannot move, accordingly, the gear 11 and the coupling 12 are also locked and cannot rotate, and thus, the other locking pin member 2 is also locked and cannot move. When the latch member 2 is connected to the locking mechanism 3, if one or both of the locking members 31 are not locked by the locking device 32 or at this time, the latch member 2 and the unlocked locking member 31 can move in the same direction under the rotation of the gear 11 and the coupling 12. If the take-off hook 4 is disconnected from the locking mechanism 3, the latch member 2 is translated by the rotation of the gear 11 and the coupling 12, regardless of whether the locking mechanism 3 is locked. The jump hook 4 is disconnected from the locking mechanism 3, i.e. the latch member 2 is disconnected from the locking mechanism 3.

Obviously, when the take-off hook 4 is connected to the hook post 331 and the lock member 31 is unlocked, it should be avoided that relative movement of the lock member 31 causes the take-off hook 4 to disengage from the hook post 331, see the movement of the balance bar 33 from state C1 to state C2 in fig. 4. The balance link 33 state C1 is the position of the balance link 33 when the lower lock 31 is locked and the upper lock 31 is unlocked and moved to the unlocked state of the latch member 2. The balance link 33 state C2 is the position of the balance link 33 when the upper lock 31 is locked and the lower lock 31 is not locked and moves to the unlocked state of the latch member 2.

Referring to fig. 4 and 5, in this embodiment, hook notch 411 is a notch defined by rounded edge 4111, inner edge 4112, and outer edge 4113, and opening in hook edge 4114. Arc edge 4111 is tangent to inner edge 4112 and outer edge 4113, and inner edge 4112 and outer edge 4113 are parallel to each other. The inner edge 4112 is an edge close to the swing hole 413, and the outer edge 4113 is an edge far from the swing hole 413. The pendulum hole 413 is used for mounting the pendulum shaft 43. Hook notch 411 is sized to match hook stem 331, i.e., radius of rounded edge 4111 is slightly larger than the diameter of hook stem 331, and when hook stem 331 snaps into hook notch 411, hook stem 331 completely sinks into hook notch 411, i.e., hook stem 331 that is sunk into hook notch 411 does not protrude beyond hook edge 4114. Furthermore, to avoid inadvertent disconnection of the jump hook 4 from the hook post 331, the line connecting the center of the swing shaft 43 and the center of the hook post 331 should be substantially parallel to the translation direction of the lock member 31. It is obvious that the line connecting the centre of the pendulum shaft 43 and the centre of the hooking stem 331 cannot always be kept parallel to the direction of translation of the capture element 31, which is determined by the active oscillating connection of the two ends of the balancing lever 33.

In addition, in order to facilitate unhooking under the operation of the door inner handle 5 when the jump hook 4 is connected to the hook post 331, in the embodiment, the hook plate 41 is a special-shaped structure plate, specifically, the hook plate 41 is a bent plate, so that an included angle B smaller than 90 degrees exists between the orientation of the hook notch 411 and the hook edge 4114 where the hook notch 411 is located. The included angle B is such that the inner edge 4112 of the hook notch 411 forms an acute angle 4115 with the hook edge 4114, and the outer edge 4113 forms an obtuse angle 4116 with the hook edge 4114. The orientation of the hook notch 411, i.e., the hook spring 42, pulls a tangent F5 to the swing direction F4 at the lower hook notch 411. The angle of the included angle B is preferably 70-80 degrees. In addition, in this embodiment, the acute angle 4115 and the obtuse angle 4116 are chamfered.

In addition, in the present embodiment, the locking mechanism 3 is an alternative locking mechanism, and includes two locking members 31 and two detent devices 32. The person skilled in the art understands that the locking mechanism 3 can also be provided with only one catch element 31 and one catch means 32. For example, referring to the embodiment, the situation where one of the locking members 31 is permanently locked by the detent device 32 corresponds to the situation where the locking mechanism 3 only includes one locking member 31 and one detent device 32.

In addition, in the present embodiment, the balance bar 33 is suspended by the locking member 31 connected to both ends, so that a gap is left between the balance bar 33 and the mounting plate 1, and the hook plate 41 is disposed in the gap between the balance bar 33 and the mounting plate 1. In order to provide sufficient clearance between the balance link 33 and the mounting plate 1, in the embodiment, referring to fig. 12, an elevated leg 312 is provided at the bottom of the locking member 31, so that the height of the balance link 33 is increased. Obviously, the locking member 31 is a block with sufficient height, and the elevating leg 312 is not needed.

Example two

The present embodiment is a specific structure of the rotation triggering mechanism implemented in relation to the telescopic tongue mechanism in the first embodiment. Referring to fig. 1, 2 and 3, the axial rotation trigger 50 includes a telescopic tongue mechanism 51.

In this embodiment, in order to enable the door inner handle 5 to be provided with the telescopic tongue mechanism 51, the door inner handle 5 includes a handle portion 581, a door panel detent groove 582, and an inner contact portion 583. Wherein, door panel detent 582 is positioned between handle portion 581 and interior portion 583. When the door inner handle 5 is provided to the door body, the inner contact portion 583 is located inside the door body, and the handle portion 581 is located outside the door body. The tongue mechanism 51 is a member provided in the inner portion 583. The inner portion 583 is a cylindrical member, and has a shaft hole 519 for connecting the coupling 12 in the middle. The coupling 12 is disposed in the shaft hole 519 such that the inner door handle 5 can rotate about the coupling 12. The handle portion 581 is fixedly attached to the inner portion 583 by a door panel capture slot 582. That is, when the handle portion 581 of the door inner handle 5 is rotated, the inner contact portion 583 is rotated in synchronization with the handle portion 581.

Referring to fig. 6, 7, 8, 9, the telescoping tongue mechanism 51 includes at least a guide chamber 511, a telescoping block 512, and a retraction spring 513 disposed at an interface 583. The guide chamber 511 is provided on the inner door handle 5 in such a manner as to be opened to the outside. The outside opening of the guide chamber 511 here means an opening on the cylindrical surface of the cylindrical member inside portion 583. The extension block 512 includes a tongue block 5121 and a guide block 5122 fixedly connected thereto. The telescopic block 512 is clamped in the guide cavity 511 through the guide block 5122, so that the telescopic block 512 can slide along the radial direction of the coupling 12, and further the tongue block 5121 can extend outwards through the outer opening of the guide cavity 511. The retraction spring 513 is disposed within the guide chamber 511 and is coupled between the guide block 5122 and the inner door handle 5 such that the retraction block 512 is pulled toward the coupling 12 by the tension of the retraction spring 513, causing the tongue block 5121 to retract into the guide chamber 511. The tongue block 5121 extends out of the guide cavity 511, that is, the telescopic block 512 extends out of the guide cavity 511, and the tongue block 5121 retracts into the guide cavity 511, that is, the telescopic block 512 retracts into the guide cavity 511.

In order to make the telescopic block 512 have a large telescopic stroke and not be locked by the coupling 12, in the embodiment, referring to fig. 10, a coupling avoiding notch 5124 is provided inside the guide block 5122. When the extension block 512 is pulled into the guide cavity 511, the coupling escape notch 5124 can receive the coupling 12.

To drive the tongue 5121 of the telescopic block 512 to extend out of the guide cavity 511, a driving block 13 is connected to the coupling 12. The drive block 13 extends into the guide chamber 511. In this embodiment, the driving block 13 is a columnar body provided on the gear 11. The telescoping tongue mechanism also includes a tack slot aperture 514. The nail slot hole 514 is an arc hole with the axis of the gear 11 as the center. The drive block 13 extends into the guide cavity 511 by passing through the staple slot aperture 514. When the shaft coupling 12 and the door inner handle 5 are relatively rotated, the driving block 13 moves along the arc-shaped nail slot hole 514 in the nail slot hole 514.

When the coupling 12 and the door inner handle 5 are relatively rotated, the driving block 13 can be moved relative to the door inner handle 5 about the axial center of the gear 11, so that the driving block 13 can be abutted against the end of the telescopic block 512. More specifically, the driving block 13 can abut on the end of the guide block 5122. When the inner door handle 5 rotates in the opening direction, the driving block 13 can be pressed against the telescopic block 512 and push the telescopic block 512 to move away from the coupling 12, so that the telescopic block 512 extends outwards through the opening on the outer side of the guide cavity 511 to be connected with the jump hook 4. In this embodiment, the telescopic block 512 is a trigger part of the rotation trigger mechanism. The telescopic block 512 extends out of the guide cavity 511, that is, the trigger part is in the second trigger position, and the telescopic block 512 is retracted in the guide cavity 511, that is, the trigger part is in the first trigger position.

Refer to fig. 6 and 7. Fig. 6 shows an initial closed state in which the latch member 2 is extended outward, that is, in the rotation trigger mechanism, the gear 11 as the first rotation portion is at a first initial angle, the handle portion 581 as the second rotation portion is at a second initial angle, and the telescopic block 512 as the trigger portion is at a first trigger position.

Fig. 7 shows the state of fig. 6 in which the extension block 512 is extended out of the guide chamber 511 after the inner door handle 5 is rotated by a certain angle in the opening direction. In this case, in the rotation trigger mechanism, the gear 11 as the first rotation portion is at the first initial angle, the handle portion 581 as the second rotation portion is at the trigger position angle, and the expansion block 512 as the trigger portion is at the second trigger position.

In fig. 6 and 7, the opening direction is the direction indicated by the arrow F0 in the drawing. In the process of fig. 6 to 7, the driving mass 13 remains in place, i.e. the gear wheel 11 and the coupling 12 are not rotated, only the inner door handle 5 is rotated. In this process, the state in which the driving block 13, the gear 11 and the coupling 12 are kept from rotating is caused by resistance generated by the latch member 2 and the like to which the gear 11 is connected or by the lock of the latch member 2 by the lock mechanism 3. In the process, the telescopic block 512 extends out of the guide cavity 511 and is connected with the take-off hook 4, and the take-off hook 4 is driven to be disconnected with the locking mechanism 3 through the rotation of the door inner handle 5 and the swinging of the telescopic block 512, so that the locking mechanism 3 unlocks the locking pin piece 2. The fig. 6 to 7 process is the functional action in the aforementioned disconnection unlocking phase.

In the process of fig. 6 to 7, that is, in the rotation trigger mechanism, the handle portion 581 as the second rotation portion is rotated from the second initial angle to the trigger position angle, and the telescopic block 512 as the trigger portion is moved from the first trigger position to the second trigger position, and at this time, the gear 11 as the first rotation portion is held at the first initial angle, thereby realizing the second necessary operational relationship described above.

Under the state of fig. 7, the door inner handle 5 is further rotated along the opening direction, on one hand, the telescopic block 512 is jacked on the jump hook 4, on the other hand, the tension of the retraction spring 513 is balanced with the resistance borne by the driving block 13, so that the telescopic block 512 can not extend outwards any more, the torque of the door inner handle 5 can only act on the driving block 13 through the telescopic block 512 and the retraction spring 513, the driving block 13 drives the gear 11 and the coupling 12 to rotate, and then the locking pin member 2 is driven to retract, and the latch opening action is realized. After a certain angle, the lock pin member 2 is limited by the translational sliding limiting mechanism 6 and cannot move back, so that the gear 11, the coupling 12 and the driving block 13 cannot rotate any more, as shown in fig. 8. The fig. 7 to 8 process is the functional action in the disconnection opening phase described above.

In the state of fig. 8, the gear 11 as the first rotation portion is located at the first stop angle, and the handle portion 581 as the second rotation portion is located at the second stop angle. In the process of fig. 7 to 8, that is, in the rotation trigger mechanism, the handle portion 581 as the second rotation portion is rotated from the trigger position angle to the second stop angle, the gear 11 as the first rotation portion is rotated from the first initial angle to the first stop angle, and the telescopic block 512 as the trigger portion is extended out of the guide chamber 511 and held at the second trigger position, thereby achieving the third necessary operational relationship.

In the state of fig. 8, after the inner door handle 5 is released, the retraction spring 513 acts to pull the retraction block 512 back, thereby bringing it into the state of fig. 9. At this time, the latch member 2 is in an open state, that is, the door latch is opened. The retraction spring 513 is also the second elastic mechanism in the aforementioned rotation trigger mechanism. In this embodiment, no matter what position the door inner handle 5 is, that is, whether the handle portion 581 as the second rotation portion is located at the second initial angle, as long as the door inner handle 5 is released, the telescopic block 512 as the trigger portion is returned from the second trigger position to the first trigger position by the retraction spring 513 as the second elastic mechanism. That is, the present embodiment satisfies the third preferred operational relationship.

As can be seen by comparing fig. 8 and 9, when the extension block 512 is retracted by the retraction spring 513, the inner door handle 5 rotates in the opposite direction to the coupling 12 in the opening direction. That is, the rotation resistance moment applied to the body of the door inner handle 5 is smaller than the moment generated by the tension of the retraction spring 513 acting on the retractable block 512 and then on the driving block 13, so that the retractable block 512 can be retracted, and the door inner handle 5 is driven to rotate in the reverse direction of the opening direction. Accordingly, reference is made to fig. 7. In the state of fig. 7, if the inner door handle 5 is released, the extension block 512 is pulled back by the retraction spring 513 under the action of the retraction spring 513, and at this time, the inner door handle 5 is rotated in the reverse direction of the opening direction under the opposing action of the retraction spring 513, so that the handle section 581 as the second rotating section is angularly returned to the second initial angle from the trigger position. That is, in the rotation trigger mechanism, the retraction spring 513 also serves as the first elastic mechanism connecting the second rotating portion, and satisfies the second preferable operational relationship.

In the state of fig. 9, if the door handle is rotated in the opposite direction of the opening direction, referring to the opposite direction of the arrow F0, the gear 11, the coupling 12 and the driving block 13 are rotated in the opposite direction of the opening direction, because the rotational resistance moment applied to the body of the door handle 5 is smaller than the moment generated by the pulling force of the retraction spring 513 on the extension block 512 and the driving block 13, the driving block 13 is pressed against the guide block 5122, and the extension block 512 and the retraction spring 513 cause the extension block 512 not to extend out of the guide cavity 511 and to rotate in the opposite direction of the opening direction with the door handle 5. At this point, the gear 11 drives the latch member 2 to extend outwardly, driving the door latch into the closed position. That is, in the present embodiment, the gear 11 as the first rotating portion is rotated from the first stop angle to the first initial angle, which is not limited to rotate the handle portion 581 as the second rotating portion from the second stop angle to the trigger position angle, but can also rotate the handle portion 581 as the second rotating portion to the second initial angle, thereby satisfying one of the preferable operational relationships.

Obviously, in the state of fig. 9, if the inner door handle 5 is rotated in the reverse direction of the opening direction, the torque of the inner door handle 5 acts on the driving block 13 through the end edge 5141 of the nail slot 514, and then the gear 11 and the coupling 12 are rotated in the reverse direction of the opening direction, and then the locking pin member 2 is driven to extend outward, at this time, the driving block 13 does not act on the telescopic block 512, and the telescopic block 512 is retained in the guide cavity 511.

It is obvious that if the door inner handle 5 is rotated in the reverse direction of the opening direction in the state of fig. 8, the telescopic block 512 can be pulled back by the retraction spring 513 to return to the state of fig. 9.

When the inner door handle 5 or the outer door handle is rotated to extend the latch member 2 outward to the closed state, if the kick-off hook 4 is disconnected from the locking mechanism 3, the hook plate 41 is under the action of the hook spring 42, so that the hook notch 411 is clamped into the hook column 331, and the locking mechanism 3 is hooked with the hook plate 41.

Obviously, the present embodiment satisfies one of the above-described necessary operational relationships, but does not satisfy four of the above-described preferred operational relationships.

It should be noted that in the present embodiment, the nail slot 514 is an arc-shaped hole, and those skilled in the art will understand that the nail slot 514 may have other shapes, such as a square hole as shown in fig. 10.

In addition, in the present embodiment, the driving block 13 is a cylindrical body disposed on the gear 11, and those skilled in the art will understand that the driving block 13 may also take other forms. For example, referring to fig. 11, the driving mass 13 is a swing mass provided on the coupling 12. When the door inner handle 5 is rotated in the opening direction, the driving block 13 can abut on the guide block 5122, referring to the state exemplified by the driving blocks 13, U in fig. 11. When the door outer handle is rotated to rotate the coupling shaft 12 in the opening direction, the driving block 13 can abut against the inner side edge 5112 of the guide chamber 511 to rotate the door inner handle 5, referring to the state illustrated by the driving blocks 13, L in fig. 11.

In addition, in this embodiment, when the locking device is opened by rotating the door inner handle 5, the retractable block 512 extends out of the guide cavity 511 and is connected with the take-off hook 4, so that the locking mechanism 3 is disconnected from the lock pin member 2, and then the door inner handle 5 is rotated continuously in the opening direction, on one hand, the retractable block 512 is pushed against the take-off hook 4, and on the other hand, the tension of the retractable spring 513 is balanced with the resistance received by the driving block 13, so that the retractable block 512 cannot extend outwards any more, the torque generated by the rotation of the door inner handle 5 can only act on the driving block 13 through the retractable block 512 and the retractable spring 513, the driving block 13 drives the gear 11 and the coupling 12 to rotate, and further drives the lock pin member 2 to retract. In the embodiment, the extension block 512 is extended to connect the jump hook 4, so that the rotation torque of the inner door handle 5 can act on the driving block 13. Those skilled in the art will appreciate that the guide cavity 511 may also be provided with a detent feature of the telescoping block 512, such that when the telescoping block 512 is extended, the telescoping block 512 can be locked by the detent feature, preventing the telescoping block 512 from continuing to extend outward, thereby allowing a rotational torque of the door inner handle 5 to be applied to the drive block 13 by reaction of the detent feature. For example, in the structure illustrated in fig. 10, the opening stoppers 515 are respectively provided on both sides of the opening 5111 outside the guide chamber 511. Therefore, when the driving block 13 pushes the telescopic block 512 to make the telescopic block 512 extend out of the guide cavity 511, both sides of the front end of the guide block 5122 can be pressed against the opening latch 515, thereby being equivalent to that the driving block 13 is pressed against the inner door handle 5. The torque generated by the rotation of the inner door handle 5 can directly act on the driving block 13 and act on the coupling 12.

EXAMPLE III

The present embodiment is a locking device with an inner and an outer opening, which is based on the first embodiment and is matched with the rotation triggering mechanism in the second embodiment, and further comprises a linkage swing mechanism 7. The linkage pendulum mechanism 7 is used for connecting the jump hook 4 and the telescopic block 512 as a trigger part, and plays a role in transmission.

The distal end of the hook plate 41 is provided with a connection part 412. The linked pendulum mechanism includes a transmission plate 71. The drive plate 71 includes a passive plate 711 and an active plate 712 connected. The joint between the driven plate 711 and the driving plate 712 is provided to the mounting plate 1 via the swing shaft 72, and the torsion spring 73 is provided to the swing shaft 72. The transmission plate 71 can return to the initial position by the torsion spring 73. When the transmission plate 71 is at the initial position, the driven plate 711 is disconnected from the hook plate 41, and the driving plate 712 faces the axis of the gear 11.

When the door inner handle 5 rotates in the opening direction and the retractable tongue mechanism 51 extends, the retractable tongue mechanism 51 can be put on the driving plate 712 at the initial position of the driving plate 71, and then the driving plate 71 is driven to surround the swinging shaft 72, so that the driven plate 711 swings towards the connecting portion 412 of the hook plate 41 and then abuts against the connecting portion 412, and thus the hook plate 41 is pushed away, and the hook column 331 is separated from the hook notch 411.

When the retractable tongue mechanism 51 is retracted and disengaged from the driving plate 712, the driving plate 71 returns to the initial position by the torsion spring 73. In the initial position of the driving plate 71, the driven plate 711 is not against the connecting portion 412, and the hook plate 41 can be driven by the hook spring 42 to make the hook notch 411 snap into the hook column 331, so that the locking mechanism 3 is connected to the hook plate 41. Referring to fig. 15, when the extension tongue mechanism 51 is extended and the door inner handle 5 is rotated in the reverse direction in the opening direction, the extension tongue mechanism 51 rides on the driving plate 712 at the initial position of the driving plate 71 and drives the driven plate 711 to swing in a direction away from the hooking stem 331, as indicated by an arrow F6, as indicated by an arrow F7.

Further, the active plate 712 is shorter than the passive plate 711, so that the active plate 712 is not connected to the hook plate 41. Therefore, in the state of fig. 9, when the door outside handle is rotated in the reverse direction of the opening direction, the gear 11, the coupling 12 and the driving block 13 are rotated in the reverse direction of the opening direction, the driving block 13 abuts on the guide block 5122, and at this time, the door inside handle 5 is locked, so that the telescopic block 512 is pushed out by the driving block 13, that is, when the telescopic tongue mechanism 51 extends and the door inside handle 5 is rotated in the reverse direction of the opening direction, the jump-up hook 4 is not connected due to the extension of the telescopic tongue mechanism 51, so that the jump-up hook 4 is not disconnected from the locking mechanism 3. That is, the linked pendulum mechanism 7 introduced in this embodiment can prevent the tripping hook 4 from being disconnected from the locking mechanism 3 due to the extension of the telescopic tongue mechanism 51 during reverse rotation. In short, the linkage pendulum mechanism 7 is a mechanism that is triggered by unidirectional swing conduction.

Specifically, the lock device of the present embodiment has the following operational characteristics:

firstly, when the locking pin piece 2 is in a closed state, namely a bolt is in a closed state, the take-off hook 4 is connected with the locking mechanism 3, the locking piece 31 is in a locking position, at the moment, the external door handle is rotated in an opening direction, and if the locking piece 31 is locked by the locking device 32, the external door handle cannot be rotated; if the position locking piece 31 is unlocked, the gear 11 drives the lock pin piece 2 to retract, the door bolt is opened, and the position locking piece 31 is driven to move correspondingly through the connection of the jump hook 4 and the locking mechanism 3.

Secondly, when the latch member 2 is in a closed state, that is, the door latch is in a closed state, and the jump hook 4 and the locking mechanism 3 are connected, the lock position member 31 is in a locked position, at this time, the door inner handle 5 is rotated in an opening direction, the jump hook 4 and the locking mechanism 3 will be disconnected under the action of the telescopic tongue mechanism 51, then the gear 11 drives the latch member 2 to retract, the door latch is opened, and at this time, the door latch can be opened by rotating the door inner handle 5 no matter whether the latch member 31 is locked by the blocking device 32.

Thirdly, when the latch member 2 is in a closed state, that is, the door latch is in a closed state, and the kick-off hook 4 and the locking mechanism 3 are connected, the latch member 2 cannot rotate either when the door outer handle or the door inner handle 5 is rotated in the opposite direction to the opening direction, as defined by the translational sliding limiting mechanism 6 connected to the latch member 2.

Fourthly, when the latch piece 2 is in an open state, namely the door bolt is in an open state, the trip hook 4 is connected with the locking mechanism 3, the door outer handle or the door inner handle 5 is rotated in the reverse direction of the opening direction, the gear 11 drives the latch piece 2 to extend outwards, the door bolt is closed, at this time, the trip hook 4 cannot be disconnected with the locking mechanism 3 no matter whether the telescopic tongue mechanism 51 extends out, the locking piece 31 is driven to move correspondingly through the connection of the trip hook 4 and the locking mechanism 3, and after the latch piece 2 moves to the closed state, the locking piece 31 correspondingly moves to a locking position. The detent device 32 can lock the locking element 31 when the locking element 31 is in the locked position.

Fifthly, when the latch member 2 is in a closed state, that is, the door latch is in a closed state, the take-off hook 4 is connected with the locking mechanism 3, and when the position locking member 31 is in a locked position, if the door outer handle is rotated to a half stroke in the opening direction and then the door inner handle is rotated in the opening direction, the take-off hook 4 and the locking mechanism 3 can be disconnected, at this time, the disconnected position of the position locking member 31 and the take-off hook 4 may be in an intermediate state, that is, the position of the position locking member 31 is not in the locked position.

Sixthly, the outer door handle is rotated in the opening direction to be in the latch closing state to be in the latch opening state, or the inner door handle 5 is rotated in the reverse direction of the opening direction to be in the latch opening state to be in the latch closing state, the jump hook 4 can be naturally connected with the locking mechanism 3 under the action of the drag hook spring 42 no matter where the locking part 31 is, namely, the locking part 31 can be connected with the locking pin part 2 through the jump hook 4 in the intermediate state. Thereafter, the door inner handle 5 or the door outer handle is rotated in the reverse direction of the opening direction from the door latch opening state to the door latch closing state, and the lock bit 31 is returned to the lock position. That is, in a state where the lock mechanism 3 and the latch member 2 are disconnected, the lock mechanism 3 and the latch member 2 are hooked by rotating the inner door outer handle.

Example four

In the second embodiment of the rotational trigger mechanism, the telescopic tongue mechanism is provided in the internal connection portion 583, and the internal connection portion 583 is fixedly connected to the handle portion 581, whereby the telescopic block 512 as the trigger portion is connected to the handle portion 581 as the second rotational portion. That is, the trigger part is connected to the second rotating part. Those skilled in the art will appreciate that the trigger portion may also be connected to the first rotating portion. Referring to the second embodiment, that is, the telescopic tongue mechanism may be connected to the gear 11 as the first rotating part. In addition, the telescopic tongue mechanism of the second embodiment has the following two problems:

the first problem is: referring to fig. 15, when the gear 11 as the first rotating portion rotates reversely in the opening direction, that is, when the first rotating portion rotates from the first stop angle to the first initial angle, if the torque resistance applied to the inner door handle 5 is large, the telescopic block 512 as the trigger portion may protrude out of the guide chamber 511 to be located at the second trigger position.

The second problem is: when the telescopic block 512 as the trigger portion is extended out of the guide chamber 511, it is synchronously rotated around the axis of the gear 11, thereby requiring a large space for the mounting plate 1.

In this embodiment, as a rotation triggering mechanism implemented by an improved telescopic tongue mechanism in the second embodiment, on the basis of the second embodiment, referring to fig. 12, the following design changes are made:

1. the handle portion 581 and the inner contact portion 583 of the door inner handle 5 are movably connected. That is, the handle section 581 and the internal connection portion 583 are coupled by a sleeve shaft so that the handle section 581 can rotate with respect to the internal connection portion 583.

2. The gear 11 as the first rotating part is connected to the telescopic block 512 as the trigger part by fixedly connecting the inner connection part 583 to the gear 11 and the coupling 12. That is, the trigger part is connected to the first rotating part.

3. The drive block 13 on the gear wheel 11 is transferred to the handle portion 581. That is, the driving block 13 is connected to the handle portion 581 as the second rotating portion. Referring to fig. 12, the driving block 13 is, for example, a cylindrical body disposed inside the handle portion 581, and penetrates into the guide cavity 511 through the nail slot hole 514.

In the rotation trigger mechanism implemented by the telescopic tongue mechanism of the present embodiment, referring to fig. 13 and 14, when the handle portion 581 is rotated from the initial position to the opening direction, the driving block 13 is driven to rotate in the opening direction, and the inner contact portion 583 of the fixed connection gear 11 is kept at a constant position. The driving block 13 rotating in the opening direction directly drives the telescopic block 512 to extend outward. Comparing fig. 6 and 7 of the second embodiment, in this embodiment, the telescopic block 512 only extends outwards and does not rotate around the axis of the gear 11.

Further, when the gear 11 as the first rotating portion is reversely rotated in the opening direction, the inner contact portion 583 fixedly connected to the gear 11 is reversely rotated in the opening direction, referring to the direction opposite to the arrow F0 in fig. 13, and at this time, the inner end of the guide block 5122 abuts against the driving block 13, thereby pushing the handle portion 581 as the second rotating portion to reversely rotate in the opening direction. At this time, the resistance of the driving block 13 to the guide block 5122 is a frictional force between the handle portion 581 and the inner portion 583, which is smaller than that of the second embodiment. Therefore, the telescopic block 512 as the trigger is less likely to protrude outside the guide chamber 511.

In addition, in this embodiment, the optional technical solution in the second technical solution may also be applied to this embodiment.

In addition, the two problems in the second embodiment are solved based on the present embodiment, which is a preferred embodiment.

EXAMPLE five

The present embodiment is a rotation trigger mechanism implemented in a cam pin structure. Referring to fig. 17, 18, and 19, in this embodiment, the inner contact portion 583 of the door inner handle 5 has a cam structure; and the trigger portion of the rotary trigger mechanism is a pin 70. That is, the door inner handle 5 includes a fixedly coupled handle portion 581 and an inner portion 583. That is, the inner contact portion 583 is fixedly connected to the second rotating portion.

The cam-structured inner contact portion 583 is provided on the coupling 12 through the central shaft hole, and includes a first arc surface portion 521 and a second arc surface portion 522. The first arc surface portion 521 and the second arc surface portion 522 are both centered on the axis of rotation of the first rotating portion and the second rotating portion, that is, the axis of the gear 11. The radius of the second arc surface portion 522 is larger than that of the first arc surface portion 521, so that the inclined surface portion 523 is connected between the first arc surface portion 521 and the second arc surface portion 522. The inclined surface portion 523 has an inner angle a1 with respect to the axial center.

A second torsion spring 529 is connected to the inner portion 583. The internal contact portion 583 and the handle portion 581 as the first rotating portion can be restored to the initial position by the elastic force of the second torsion spring 529. That is, the present embodiment satisfies the second of the above-described preferred operational relationships. The second torsion spring 529 is the first elastic mechanism. Obviously, the present embodiment satisfies one of the aforementioned preferred action relationships.

The first rotation portion is connected to a first driving connection portion 5251. The first drive connection portion 5251 is a columnar drive block 13 provided on the disk surface of the gear 11 as the first rotation portion. That is, the gear 11 serves as a discoid body. The second rotation portion is connected to a second driving connection portion 5252. Specifically, the inner contact portion 583 fixedly connected to the handle portion 581 as the second rotating portion is provided with a second nail hole 524. The second nail slot hole 524 is an arc hole with the axis as the center. The drive block 13 is captured within the second staple slot aperture 524. The second drive connection 5252 is the terminal edge 5241 of the second staple slot aperture 524.

Referring to fig. 21, a pin 70 as a trigger is formed in a long bar shape, is arranged in a radial direction of the axis of the gear 11, and is provided on a slide guide sleeve 74. The slide guide sleeve 74 serves to define the direction of the sliding displacement of the pin rod 70 so that the pin rod 70 can be displaced in the radial direction of the axial center of the gear 11. The slide guide sleeve 74 is a member for guiding the movement as described above. The means for guiding the movement are of many kinds, such as the aforesaid translational sliding limiting mechanism 6. One end of the pin 70 abuts the inner contact portion 583, which is the driving end. The driving end of the pin 70 is provided with a driving end projection 701. A top wheel spring 75 sleeved on the rod body of the pin rod 70 is arranged between the driving end bulge 701 and the sliding guide sleeve 74. The top wheel spring 75 is for providing an elastic force so that the driving end of the pin lever 70 can always abut on the inner abutting portion 583, specifically, the first arc surface portion 521, the second arc surface portion 522, or the slope surface portion 523. When the driving end of the pin rod 70 is pressed against the first arc surface part 521, the pin rod 70 as a trigger part is at a first trigger position; when the driving end of the pin 70 abuts against the second curved surface portion 522, the pin 70 as the trigger is in the second trigger position. The top wheel spring 75 corresponds to the second elastic means, so that the present embodiment satisfies the third preferred operation relationship.

Referring to fig. 17, fig. 17 is an initial state. In the initial state, the gear 11 as the first rotation portion is at the first initial angle, referring to the B1 position where the drive block 13 is located. In the initial state, the second rotating portion is at the second initial angle, referring to the P1 position where the internal connection portion 583 is located. At this time, one end of the pin lever 70 abuts on the junction between the inclined surface portion 523 and the first arc surface portion 521, and the pin lever 70 as the trigger portion is in the first trigger position. At this time, the driving block 13 as the first drive connection 5251 has an included angle a2 with the end edge 5241 of the second staple slot hole 524 as the second drive connection 5252. The included angle a1 is the same as the included angle a 2.

In the initial state, when the gear 11 as the first rotating portion is rotated in the opening direction, that is, the first rotating portion is rotated from the first initial angle to the first stop angle, the driving block 13 as the first driving connecting portion 5251 is rotated in an arc shape within the second nail groove hole 524 to the B2 position. At this time, that is, there is no interaction between the first and second

driving connection portions

5251 and 5252, the internal contact portion 583 fixedly connected to the second rotating portion is kept still, that is, the second rotating portion stays at the second initial angle. Similarly, when the gear 11 as the first rotation portion is rotated in the reverse direction of the opening direction, that is, the first rotation portion is rotated from the first stop angle to the first initial angle, the second rotation portion can be maintained at the second initial angle as well. Therefore, the present embodiment not only satisfies one of the necessary operational relationships, but also satisfies four of the preferred operational relationships.

In the state of fig. 17, the handle portion 581 is rotated in an opening direction, that is, the inner joint portion 583 is rotated to the state of fig. 18. In the state of fig. 18, the gear 11 as the first rotating portion is held at the first initial angle, and the second rotating portion is at the trigger position angle, which is referred to as P2 angle where the internal connection portion 583 is located. In the state of fig. 18, the end of the pin lever 70 is pressed against the connection between the inclined surface portion 523 and the first arc surface portion 521, and the pin lever 70 as the trigger is at the second trigger position, and the pin lever 70 is pushed by a distance in the direction away from the axial center as compared with fig. 17.

The process of fig. 17 to 18 is the action process of the aforementioned disconnection unlocking stage. In the process, the angle that the inner portion 583 rotates through is an included angle a 1. Since angle a1 and angle a2 are the same, that is, the terminal edge 5241 of second staple slot aperture 524, which is second drive connection 5252, is rotated through angle a2, respectively, so that terminal edge 5241 bears against drive block 13, effecting the connection of first drive connection 5251 and second drive connection 5252. That is, when the second rotating part is rotated from the second initial angle to the striking position angle, the second driving connecting part 5252 is connected with the first driving connecting part 5251. In this process, the end of the pin rod 70 is driven by the inclined surface portion 523, so that the pin rod 70 is pushed a distance away from the axial center, that is, the pin rod 70 as the trigger is pushed from the first trigger position to the second trigger position by the inclined surface portion 523. In this process, the gear 11 as the first rotation portion and the second rotation portion are maintained at the first initial angle without interaction therebetween. That is, the present embodiment satisfies the second of the above-mentioned necessary operational relationships.

In the state of fig. 18, the handle portion 581 is further rotated in the opening direction, and the internal portion 583 is rotated to the state of fig. 19. In the process of fig. 18 to 19, the handle portion 581 as the second rotating portion is rotated from the trigger position angle to a second stop angle, which refers to an angle P3 where the inscribed portion 583 of fig. 19 is located. In this process, the end edge 5241 of the second slot 524 serving as the second driving connection 5252 abuts against the driving block 13 serving as the first driving connection 5251, so that the driving block 13 and the gear 11 are driven to rotate, and the gear 11 serving as the first rotating part is rotated from a first initial angle to a second initial angle, which can be referred to as the B1 position and the B2 position of the driving block 13, respectively. Thereby, the latch member of the connecting gear 11 is moved from the closed state to the open state. In this process, the end of the pin 70 abuts against the second arc surface portion 522, so that the pin 70 as the trigger is always held in the second trigger position. That is, the present embodiment satisfies the third of the above-described necessary operational relationships.

Compared with the rotation trigger mechanism realized by the telescopic tongue mechanism in the second embodiment and the fourth embodiment, the rotation trigger mechanism of the present embodiment has at least the following three different action relationships:

first, in the structure of the present embodiment, when the gear 11 as the first rotating portion is rotated from the first initial angle to the first stop angle, the handle portion 581 as the second rotating portion is kept at the second initial angle, and in the second and fourth embodiments, the first rotating portion drives the second rotating portion to rotate by a corresponding angle.

Second, with the structure of this embodiment, only when the second rotating portion has the second initial angle, the triggering portion may return to the first triggering position from the second triggering position by the elastic force of the second elastic mechanism. In the second and fourth embodiments, no matter the angle to which the second rotating portion rotates, as long as the second rotating portion is released, the triggering portion can be returned to the first triggering position by the retraction spring 513.

Third, in the structure of the present embodiment, the pin 70 as the trigger moves only in the radial direction of the shaft center, whereas in the second and fourth embodiments, the telescopic block 512 as the trigger can rotate with the first rotating portion or the second rotating portion.

In addition, in the above embodiment of the present embodiment, the driving connection relationship between the second driving connection portion 5252 and the first driving connection portion 5251 is realized by the arc-shaped second nail slot hole 524 provided on the internal connection portion 583 and the driving block 13 of the columnar body provided on the disk surface of the gear 11. Those skilled in the art will appreciate that the second arcuate staple slot aperture 524 may also be provided in the face of the plate of the gear 11, with the drive block correspondingly provided on the inner interface 583. That is, the first driving connection portion 5251 is an arc-shaped groove provided on the disk body. The second drive connection 5252 is a bump provided on the disk surface of the inward portion 583. The second drive connection 5252 is captured within the arcuate slot.

In addition, the first drive connection portion 5251 and the second drive connection portion 5252 can be implemented in other ways, for example, in fig. 20, the first drive connection portion 5251 is a swing block provided on the coupling 12, and the second drive connection portion 5252 is a bump provided on the disk surface of the inner connection portion 583. In the initial state, the first drive connection portion 5251 and the second drive connection portion 5252 form an angle a2 with respect to the axial center.

In addition, the included angle a2 between the first drive connection portion 5251 and the second drive connection portion 5252 with respect to the axis and the included angle a1 between the inclined surface portion 523 with respect to the axis have the same included angle a1 and the included angle a 2. Those skilled in the art will appreciate that the included angle A2 may also be greater than the included angle A1.

EXAMPLE six

The present embodiment is a locking device with an inner and an outer opening, and on the basis of the first embodiment, the locking device further includes a linkage swing mechanism 7 in cooperation with the rotation triggering mechanism of the fifth embodiment. The linkage pendulum mechanism 7 has the same structure as that in the third embodiment, and is not described again. In this embodiment, the opposite end of the driving end of the pin lever 70 is pressed against the driven plate 711. When the pin 70 as the trigger moves from the first trigger position to the second trigger position by the internal contact portion 583 of the cam structure, the driven plate 711 is pushed to bring the driving plate 712 against the connecting portion 412 of the hook plate 41, see fig. 18 and 19, thereby disconnecting the trip hook 4 from the lock mechanism 3. With this arrangement, it will be appreciated by those skilled in the art that the opposite end of the driving end of the pin 70 is directly movably connected to the passive plate 711 via a hinge. In the embodiment in which the pin lever 70 and the driven plate 711 are movably coupled by a hinge, since the torsion spring 73 is coupled to the driving plate 71 where the driven plate 711 and the driving plate 712 are located, and the head wheel spring 75 is coupled to the pin lever 70. The torsion spring 73 and the top wheel spring 75 may be regarded as a repetitive elastic mechanism, and one of them may be omitted. In the case where the top wheel spring 75 is omitted, the torsion spring 73 may function as the aforementioned second elastic mechanism, so that the pin lever 70 as the trigger returns to the first trigger position. In the case of omitting the torsion spring 73, the top wheel spring 75 brings the transmission plate 71 to return to the initial position while returning the pin lever 70, which acts as a trigger, to the first trigger position.

In the above embodiments of the present specification, two greatly different rotation triggering mechanisms are provided, and the locking device which is opened from inside to outside and is realized by the two rotation triggering mechanisms. Those skilled in the art will appreciate that there are numerous specific embodiments that can be implemented for the rotary trigger mechanism, that the two rotary trigger mechanisms of the present embodiment can also be derived from specific configurations, and that the descriptions of the specific embodiments of the present disclosure are intended to be exemplary only.

Further, this specification describes the door outer handle, although not specifically illustrated in the drawings, without hindering the understanding of those skilled in the art. Furthermore, the door outer handle is only a component for driving the locking device to open, and should not be specifically understood as a component operated by a human, but the door outer handle may also be a component electrically controlled and driven to rotate, such as a component implemented by a motor or a permanent magnet mechanism. In addition, the aforementioned "handle" in the present specification means a handle provided in the door, that is, the door inner handle 5. It should be noted that the inner door handle 5 is also merely an example, and the inner door handle 5 may be a member that is electrically controlled and driven to rotate. In this embodiment, the handle portion 581 may be a gear connected to a motor. Even if the door inner handle 5 is a manually operated member, the handle portion 581 may be only one member for connecting the manually operated member. Such as handle portion 581 for attachment to a wheel handle.

In addition, the rotation trigger mechanism in this specification is a member designed for a lock device that is opened inward and outward. Those skilled in the art will appreciate that the rotary trigger mechanism may be used in other applications as desired.
