The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The handle inside the door and the handle outside the door are not linked conveniently, so that the purpose that the handle inside the door and the handle outside the door act independently without mutual influence is achieved; the present invention provides another contemplated non-linked lock body. The method comprises the following specific steps:

fig. 1 shows an unlinked lock body of a preferred embodiment of the present invention, which includes a housing 1, a driving mechanism 2, a clutch assembly 3, and a main bolt assembly 4.

Referring to fig. 2, the locking main tongue assembly 4 includes a moving member 41, a shift lever 42 and a locking main tongue 43 mounted (fixed or elastically connected by a spring) on the moving member 41, the locking main tongue 43 is movably inserted into the housing 1, a first end of the shift lever 42 close to the clutch assembly 3 (see fig. 1) is pivotally connected to the housing 1, one of a second end of the shift lever 42 far from the clutch assembly 3 and the moving member 41 is provided with a guide slot 421, and the other is provided with a guide post 411. When the shift lever 42 swings relative to the housing 1, the guide column 411 moves relative to the guide groove 421 along the length direction of the guide groove 421 (according to the common knowledge, the length direction of the guide groove 421 is perpendicular to the depth direction thereof, i.e., the groove depth direction) to make the moving member 41 move linearly, so that the main latch 43 extends and contracts relative to the housing 1.

For ease of understanding, please refer to fig. 4-7. With particular reference to fig. 4, the clutch assembly 3 comprises a first rotating seat 31, a second rotating seat 32 and a linkage seat 33, all coaxially arranged. The first rotating seat 31 and the second rotating seat 32 are provided with hole sites, bosses or slots 34 for mounting handles. The linkage seat 33 has a collar 331, the first rotating seat 31 is inserted into and movably sleeved with the inner ring 3311 of the collar along a first end of the collar 331, and the second rotating seat 32 is inserted into and movably sleeved with the inner ring 3311 of the collar along a second end of the collar 331. Referring to fig. 6, the collar 331 is provided with a through hole 332 along the radial direction thereof, a first return spring 333 is embedded in the through hole 332, a clutch pin 334 is further inserted in the through hole 332, and the first return spring 333 is sleeved on the clutch pin 334 and enables the clutch pin 334 to have a movement tendency away from the axis of the collar 331 along the radial direction of the collar 331 in a natural state.

Referring to fig. 7, the linkage seat 33 is further provided with a selection linkage member 35, the first rotation seat 31 protrudes along the radial direction thereof to form a first selected linkage portion 311, and the second rotation seat 32 protrudes along the radial direction thereof to form a second selected linkage portion 321. Only one of the first selected linkage part 311 and the second selected linkage part 321 can toggle the selection linkage piece 35, so that the linkage seat 33 rotates reversely around the axis thereof; the other is provided with a first notch 3111 corresponding to the clutch pin 334 for accommodating the clutch pin 334, and the clutch pin 334 is located outside the first notch 3111 in a natural state. That is, only one of the first selected linking part 311 and the second selected linking part 321 must be located at a position where the selecting link 35 can be toggled, so that the selecting link 35 can be toggled when the selecting link rotates, and the other one cannot toggle the selecting link 35 in the idle rotation condition, i.e. the other one must be engaged with the first notch 3111 through the clutch pin 334 to toggle the selecting link. Thus, one of the first rotating seat 31 and the second rotating seat 32 can drive the linkage member to rotate unconditionally in the door, so that a series of door opening actions are realized, and the other one is not linked during operation; while the other one can control the rotation of the linkage shaft to solely realize the door opening action on the premise that the clutch pin 334 is inserted into the first notch 3111.

Referring to fig. 2, the driving mechanism 2 is used to drive the clutch pin 334 to be inserted into the first notch 3111.

Here, it should be preferentially explained that:

defining: in fig. 1 to 9, the clockwise direction is the forward direction, and the counterclockwise direction is the reverse direction. That is, clockwise when viewing FIGS. 1-9, i.e., forward; when rotated clockwise, as viewed in FIGS. 1-9, the rotation is in the opposite direction.

The linkage seat 33 protrudes along a direction perpendicular to the axial direction of the linkage seat 33 to form a first shifting block 335 (see fig. 2), and when the linkage seat 33 rotates in the opposite direction relative to the axial direction, the first shifting block 335 can press the first end of the shift lever 42, so that the shift lever 42 swings to drive the main lock tongue 43 on the moving member 41 to contract.

Referring to fig. 4 and fig. 2, when the first rotating base 31 rotates forward around its axis, the first selected linking portion 311 (see fig. 2 or fig. 7) presses the first end of the shift lever 42, so that the shift lever 42 swings to drive the main latch 43 on the moving member 41 to extend; and when the second rotating base 32 rotates forward around its axis, the second selected linkage portion 321 (see fig. 7) presses the first end of the shift lever 42, so that the shift lever 42 swings to drive the main latch 43 on the moving member 41 to extend.

Obviously, the non-linkage lock body of the embodiment achieves the purpose of controlling the rotation of the linkage seat 33 by the first rotating seat 31 and the second rotating seat 32 independently on the basis of utilizing the clutch assembly 3. That is, when the first rotating seat 31 controls the linkage seat 33 to rotate, the second rotating seat 32 is in a stationary state; when the second rotating seat 32 controls the linkage seat 33 to rotate, the first linkage seat 33 is in a static state. By the arrangement, the non-linkage of the inner handle and the outer handle of the door can be realized. On the basis, the first rotating seat 31 and the second rotating seat 32 both rotate the linkage seat 33, so that the shifting rod 42 is shifted by the linkage seat 33 to unlock (i.e. the shifting rod 42 drives the main bolt 43 to unlock); and when the first rotating seat 31 and/or the second rotating seat 32 rotate in the forward direction, the main lock tongue 43 can be locked (that is, the shift lever 42 drives the main lock tongue 43 to extend out of the housing 1 for locking). Moreover, one of the first selected linkage portion 311 and the second selected linkage portion 321, which can select the linkage 35, can achieve unconditional control of the rotation of the linkage seat 33 (i.e. it is not necessary for the clutch pin 334 to be inserted into the first notch 3111 as a precondition), while the other requires the clutch pin 334 to be inserted into the first notch 3111 as a precondition, so that the purpose of opening the door by unconditional unlocking inside the door and opening the door by outside the door by satisfying the conditions is achieved. In addition, the clutch has compact structure and convenient manufacture, thereby being beneficial to the manufacture of the non-linked lock body and having reliable control mode.

It should be noted that, in practical applications, the driving mechanism 2 may be operated based on the existing mature wired or wireless control technology, so that the driving mechanism 2 may drive the clutch pin 334 to be inserted into the first notch 3111.

It should be additionally explained that, in fig. 2, the moving member 41 is a component of the linkage main latch 43, and mainly makes a linear motion to achieve the extension or contraction of the main latch 43, and the specific structure of the moving member 41 may be a thin plate structure, or a regular or irregular structure, that is, the specific structure has no substantial influence. In fig. 2, in the matching of the guide groove 421 and the guide column 411, the guide groove 421 may be in a closed-loop structure or an open-loop structure, or may be formed by two spaced blocks as long as linear guiding is possible; the guiding column 411 may be a part formed by a protrusion of the shift lever 42 or the moving member 41, or may be a component fixed on the shift lever 42 or the moving member 41 in a fixed or detachable manner. Obviously, the structure of the lock can be realized only by controlling the extension and retraction of the main bolt 43 through the guide slot 421 and the guide column 411. In addition, it should be mentioned that the driving mechanism 2 may be a combination of screws of the motor 21, or the motor 21 drives a transmission belt or a chain to drive a pressing block to press the clutch pin 334, and obviously, the selection of the driving mechanism 2 is not exhaustive.

In order to further optimize the technical scheme:

preferably, referring to fig. 4 and 7, the first notch 3111 is disposed on the first rotating seat 31, the second rotating seat 32 is provided with a second notch 3211 at a position corresponding to the clutch pin 334 for accommodating the clutch pin 334, the first notch 3111 and the second notch 3211 form a combination notch 336 for accommodating the clutch pin 334, and the driving mechanism 2 is configured to drive the clutch pin 334 to be inserted into the combination notch 336. The selection linkage 35 is detachably connected to the linkage seat 33, so that the selection linkage 35 can be shifted by the first selected linkage part 311 or the second selected linkage part 321. By such arrangement, as long as the clutch pin 334 is inserted into the combining notch 336, the first rotating seat 31 or the second rotating seat 32 can independently drive the linkage seat 33 to rotate, so as to realize unlocking and door opening; thus, after the non-linked lock body is installed on the front or back according to actual conditions (such as according to the orientation of the handle), the selection linkage member 35 is detached and detachably installed, so that the selection linkage member can be driven by one of the first rotating seat 31 or the second rotating seat 32, and the other one can drive the linkage seat 33 on the basis of the matching of the clutch pin 334 and the combining notch 336. Set up like this for this non-linkage lock body has stronger commonality, can be suitable for different door structures and be suitable for different handle orientations.

Preferably, the selective linkage member 35 has a threaded section, and the linkage seat 33 is provided with a threaded through hole 332 in threaded fit with the threaded section, or the linkage seat 33 is symmetrically provided with two threaded blind holes in threaded fit with the threaded section. Obviously, the part having the threaded section has a screw, bolt, jackscrew, stud, etc. However, the selective link 35 may be detachably connected by a screw connection, or may be directly connected by a conventional technical means such as snap connection or simple insertion; or it may be a combination of plugging and clamping. However, the threaded connection is obviously convenient for installation and disassembly, and the fixing mode is firm and safe.

Preferably, referring to fig. 1, the housing 1 is provided with a first stroke limiting hole 11 and a second stroke limiting hole (not shown) at two opposite sides, the first rotating seat 31 has a first limiting portion 312 (see fig. 2), and the second rotating seat 32 has a second limiting portion (not shown); the first position-limiting portion 312 is adapted to the first stroke-limiting hole 11 to limit the limit angle of the first position-limiting portion 312 swinging around the axis of the first rotating base 31, and the second position-limiting portion is adapted to the second stroke-limiting hole to limit the limit angle of the second position-limiting portion swinging around the axis of the second rotating base 32.

Preferably, referring to fig. 1, the non-interlocking lock body further comprises a latch bolt assembly 5 and a latch bolt driver 6. Referring to fig. 2 in this paragraph, the latch assembly 5 includes a latch 51, a moving rod 52 fixedly connected to the latch 51, and a second return spring 53 sleeved on the moving rod 52. Two ends of the second return spring 53 respectively abut against the latch tongue 51 and the housing 1, and the second return spring 53 is used for driving the latch tongue 51 to extend out of the housing 1. And a limit block 54 is arranged at one end of the moving rod 52 far away from the latch tongue 51. The latch bolt shifting piece 6 (see fig. 1) is pivotally connected with the shell 1, the latch bolt shifting piece 6 is positioned at one side of the clutch component 3, and the rotation axis of the latch bolt shifting piece 6 is coaxially arranged with the axis of the first rotation seat 31. The latch tongue shifting piece 6 is formed by protruding along the radial direction of the axis of the latch tongue 51, and a second shifting block 61 and a third shifted block 62 are arranged at intervals along the circumferential direction of the axis of the latch tongue 51. The coupling seat 33 protrudes axially to form a fourth shifting block 36 (please specifically refer to fig. 2 and 3, the fourth shifting block 36 is used for pressing the third shifted block 62 to rotate the third shifted block 62 in the opposite direction). The second shifting block 61 abuts against the limiting block 54, and the third shifted block 62 abuts against the fourth shifting block 36; when the linkage seat 33 (see fig. 4, wherein the linkage seat 33 is driven by the first rotating seat 31 or the second rotating seat 32) rotates in the opposite direction around its axis, the fourth shifting block 36 shifts the third shifted block 62 to make the latch bolt shifting piece 6 rotate along with the linkage seat 33, and further the second shifting block 61 shifts the limiting block 54 to make the latch bolt 51 retract. It should be additionally explained here that, obviously, the latch assembly 5 and the latch driver 6 are automatically reset by the second return spring 53. With this arrangement, the link base 33 can rotate in the reverse direction and simultaneously rotate the latch lifting piece 6 in the reverse direction to unlock the latch 51 (i.e., to retract the latch 51). Thus, one-step opening of the door can be realized (i.e. the synchronous opening of the latch bolt 51 and the main latch bolt 43 can be realized through the linkage seat 33).

Preferably, referring to fig. 2, the driving mechanism 2 includes a motor 21, a driven shaft 22 in transmission connection with the motor 21, a movable seat 23 movably sleeved on the driven shaft 22, and a transmission spring 24 sleeved on the driven shaft 22. The transmission spring 24 is fixed on the moving seat 23, the driven shaft 22 is protruded with a transmission rod 25 along the radial direction thereof, and the transmission rod 25 penetrates along the radial direction of the transmission spring 24 to drive the transmission spring 24 to move along the axial direction of the driven shaft 22. The moving seat 23 has a pressing portion for pressing the clutch pin 334. Obviously, upon rotation of the driven shaft 22, the transmission rod 25 rotates synchronously with the driven shaft 22, forcing the spring to move, so that the pressing portion of the moving seat 23 presses or releases the clutch pin 334.

Preferably, the driving mechanism 2 further includes a driving gear 27 in driving connection with the motor 21, and a driven gear 26 in transmission connection with the driving gear 27, and the driven shaft 22 is fixedly connected to the driven gear 26. Obviously, the reduction of the speed of the mobile seat 23, slowing the rigid impacts, is achieved by the cooperation of the driving gear 27 with the driven gear 26.

Preferably, referring to fig. 8, the non-linked lock body further comprises a torsion member 7 and a locking mechanism 8. Referring to fig. 9, the linkage seat 33 protrudes in a radial direction thereof to form a fifth shifting block 37, and the torsion member 7 protrudes in a radial direction thereof to form a sixth shifted block 71 and a seventh shifted block 72. The fifth shifting block 37 abuts against the sixth shifted block 71, and the fifth shifting block 37 is used for driving the sixth shifted block 71 to rotate in the reverse direction. The locking mechanism 8 includes a locking moving piece 81 and a locking cylinder 82 disposed on the locking moving piece 81, a locking groove 412 is disposed on the moving member 41 of the main bolt assembly 4, and the locking cylinder 82 is used for locking the locking groove 412. The seventh shifting block 72 abuts against the locking moving piece 81 and is used for driving the locking moving piece 81 to move so as to disengage the locking column 82 from the locking groove 412. With this arrangement, when the first rotary seat 31 or the second rotary seat 32 drives the linkage seat 33 to rotate in the reverse direction to unlock the main bolt 43 and the latch bolt 51, the locking moving piece 81 can drive the locking cylinder 82 to disengage from the locking groove 412, so as to prevent the locking cylinder 82 from locking the moving member 41 (see fig. 2) of the main bolt assembly 4 (i.e., to avoid interfering with the contraction of the moving member 41).

Preferably, the locking mechanism 8 further includes a third elastic return element for driving the locking cylinder 82 to be inserted into the locking groove 412. Thus, in the natural state, the locking cylinder 82 fits into the locking groove 412. Therefore, under the condition that the non-linkage seat 33 is driven, the moving member 41 (see fig. 2) is locked, namely, the moving member 41 is contracted, so that the main lock tongue 43 cannot be unlocked, and the anti-theft effect is better.

Wherein, the third elastic restoring element is a torsion spring, a spring (i.e. a compression spring or a tension spring), a belt or a rubber belt, etc.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
