Example 1
As shown in fig. 1, the present invention exemplarily uses a first member 10 having a plate shape and a second member 20 having a plate shape as a connection object, to illustrate one embodiment of the connection assembly of example 1 of the present invention shown in fig. 3 to 15.
The material of the first member 10 and the second member 20 may be wood, or may be other materials, such as metal, plastic, glass, or composite materials. Furthermore, both the first member 10 and the second member 20 may be made of different materials.
Referring to fig. 1-2, in the connected state of the first member 10 and the second member 20, a first connection surface 102 of the first member 10 and a second connection surface 202 of the second member 20 are formed, wherein the first connection surface 102 and the second connection surface 202 are attached to each other, and meanwhile, a first arc-shaped groove 101 is formed on the first connection surface 102 and a second arc-shaped groove 201 is formed on the second connection surface 202 by means of machining. Further, referring to fig. 18 to 19, according to the structures and sizes of the first arc-shaped groove 101 and the second arc-shaped groove 201, the first connecting member 1 and the second connecting member 2 are respectively arranged in a half-moon shape, so that the first connecting member 1 can slide in along the arc-shaped bottom wall 101c of the first arc-shaped groove, the second connecting member 2 can slide in along the arc-shaped bottom wall of the second arc-shaped groove, simultaneously, the first connecting member 1 can be fully accommodated in the first arc-shaped groove 101, the second connecting member 2 can be fully accommodated in the second arc-shaped groove 201, and then the first connecting member 1 and the second connecting member 2 are connected with each other through the first connecting surface 102 and the second connecting surface 202 so that the first member 10 and the second member 20 are in contact with each other through the first connecting surface 102 to complete connection.
Referring to fig. 4-17, in order to achieve the detachable connection of the first connector 1 and the second connector 2, a connection assembly according to embodiment 1 of the present invention further includes a locking member 3 and a bolt member 5; the first connecting piece 1 is provided with a first slotted hole 12 for accommodating the bolt 5, the first connecting piece 1 is provided with an inserting groove 11, one end of the locking piece 3 is inserted into the inserting groove 11, the other end of the locking piece 3 is detachably connected with the second connecting piece 2, and the locking piece 3 is provided with a second slotted hole for inserting the bolt 5; when the external force drives the bolt 5 to slide or rotate, the bolt 5 can be moved out of the second slot hole, so that the locking piece 3 can be pulled out of the inserting groove 11.
In this embodiment 1, the specific number of the locking member 3, the insertion groove 11 and the bolt 5 is not limited. It will be appreciated that the number of locking members 3 may be one or more, and that the number of mating grooves 11 is adapted to the same as the number of locking members 3; the number of bolts 5 may be the same as the number of locking members 3, or may be greater or less than the number of locking members 3. According to the actual working requirements, a person skilled in the art correspondingly selects a plurality of locking members 3, inserting grooves 11 and bolts 5 to control the locking effect between the first connecting member 1 and the second connecting member 2 and the locking effect of the bolts 5 on the locking members 3. In general, the greater the number of locking members 3, the stronger the locking effect of the first connector 1 and the second connector 2; the greater the number of bolts 5, the greater the locking effect of the bolts 5 on the locking member 3.
The insertion groove 11 of the present embodiment 1 may be located in the middle of the surface of the first connector 1 or may be located at the edge of the surface of the first connector 1. The insertion groove 11 is used for limiting the locking piece 3 to swing left and right or back and forth in the horizontal direction, and plays a limiting role.
Wherein the first slot hole 12 can be communicated with the inserting slot 11, namely, the bolt 5 is connected with the part of the locking piece 3 inserted into the inserting slot 11; the first slot 12 may also be left out of communication with the socket 11, i.e. the peg 5 is connected to the locking element 3 at a portion which is not inserted into the socket 11. In order to improve the connection stability of the bolt 5 and the locking member 3, referring to fig. 5 to 16, the first slot 12 of the present invention is preferably communicated with the insertion slot 11, so that the overall structure is more compact and firm.
Wherein, in order to facilitate the installation of the bolt 5 in the first slot 12, at least one side of the first slot 12 penetrates through the sidewall of the first connecting piece 1 to form a plugging port 123 for inserting the bolt 5. Meanwhile, in order to prevent the plug 5 from being removed from the socket 123 after the plug 5 is mounted to the first slot 12, a plug body for restricting the removal of the plug 5 from the socket 123 is provided in the first slot 12, and the plug body is preferably provided at the socket 123.
Based on the above structure, after the locking member 3 is inserted into the inserting groove 11, the bolt 5 in the first slot 12 is driven by an external force (the external force may be a screwdriver pushing the bolt 5) to insert into the second slot, the bolt 5 plays a limiting role on the locking member 3, and limits the movement of the locking member 3 relative to the first connecting member 1, so that the locking member 3 is fixed in the inserting groove 11, and the first connecting member 1 and the second connecting member 2 are connected with each other through the locking member 3 and the bolt 5. When the external force drives the bolt 5 to slide or rotate, the bolt 5 can move out of the second slot hole, the limiting effect of the bolt 5 on the locking piece 3 is relieved, and the locking piece 3 can be pulled out of the inserting groove 11, so that the first connecting piece 1 and the second connecting piece 2 are separated from each other. According to the embodiment 1, the connection relation between the control bolt piece 5 and the locking piece 3 is controlled, so that the first connecting piece 1 and the second connecting piece 2 can be quickly installed or detached, the assembly efficiency is high, the defects of the conventional laminode invisible connecting piece structure and troublesome operation are overcome, and the convenience of invisible piece installation is improved.
The following is a further explanation of a specific structure of the connection assembly of embodiment 1 of the present invention. Referring to fig. 5 to 16, the bolt 5 of the present embodiment 1 is slidably disposed in the first slot 12, so that the bolt 5 can move in the first slot 12 under the driving of an external force, and the positional relationship between the bolt 5 and the locking member 3 is controlled.
As a first solution, referring to fig. 5-9 and 23, when the bolt 5 slides in the first slot 12, the second slot of the present embodiment 1 is a second through hole 31 penetrating through both sides of the locking member 3, and when one end of the locking member 3 is inserted into the insertion slot 11, the second through hole 31 is located in the insertion slot 11, so that the bolt 5 may be able to pass through the second through hole 31. When the external force drives the bolt 5 to pass through the second through hole 31 and stay in the second through hole 31, the bolt 5 plays a limiting and fastening role on the locking piece 3, and the locking piece 3 is limited to be pulled out of the inserting groove 11.
In the above-mentioned scheme, when the first connecting member 1 and the second connecting member 2 are in the connected state, in order to avoid the plug member 5 moving out of the second through hole 31 and ensure the connection stability of the first connecting member 1 and the second connecting member 2, referring to fig. 6-7, a clamping point for limiting the sliding of the plug member 5 is provided on the inner side wall of the second through hole 31 in embodiment 1. The jamming point generates certain friction force on the bolt 5, so that abnormal displacement of the bolt 5 in the second through hole 31 is limited, and the jamming point plays a role in positioning the bolt 5. The snap-fit point may be made of an elastic material to increase the friction of the plug 5 in the second through hole 31, which may further prevent the plug 5 from being removed from the second through hole 31 under abnormal conditions.
Referring to fig. 6-7, the cross-sectional area of the first slot 12 of embodiment 1 is larger than the cross-sectional area of the second through hole 31. When the first connecting piece 1 is detached from the second connecting piece 2, the bolt 5 can be driven to move out from the second through hole 31 into the first slot hole 12, and at the moment, the central axis of the bolt 5 positioned in the first slot hole 12 is lower than the central axis of the second through hole 31, so that the assembly error is larger, the bolt 5 is difficult to enter the second through hole 31 again, and misoperation in the detachment process is prevented.
In addition, in this embodiment 1, the bolt 5 may be configured to have a variable diameter structure or a protrusion may be provided on the surface of the bolt 5 or other means to increase the friction force on the surface of the bolt 5, so as to prevent the bolt 5 from being removed from the second through hole 31 in a non-detachable manner.
As a second alternative, referring to fig. 24, when the bolt 5 slides in the first slot 12, the second slot of the embodiment 1 is a second blind hole 32 provided on the surface of the locking member 3, and when one end of the locking member 3 is inserted into the insertion slot 11, the second blind hole 32 is located in the insertion slot 11, so that the end of the bolt 5 can be inserted into the second blind hole 32. When the end of the external force driving bolt 5 is inserted into the second blind hole 32, the bolt 5 plays a role in limiting and fastening the locking piece 3, and the locking piece 3 is limited to be pulled out from the inserting groove 11.
In order to improve the balance stability of the locking member 3 during the limit of the plugging slot 11, the number of the second blind holes 32 in the second scheme is two, the second slotted holes are axially symmetrically arranged relative to the locking member 3, and meanwhile, the number of the bolt members 5 is two, and the two second blind holes 32 are in one-to-one correspondence with the two bolt members 5. Specifically, one of the bolt pieces 5 slides in the first slot hole 12 and enables the end part of the bolt piece to be inserted into one of the second blind holes 32, the other bolt piece 5 slides in the first slot hole 12 and enables the end part of the bolt piece to be inserted into the other second blind hole 32, and limiting fastening acting forces are formed on two opposite sides of the locking piece 3 through the two bolt pieces 5 respectively, so that the locking effect of the locking piece 3 in the inserting slot 11 is effectively improved. In order to prevent the end portion of the bolt 5 from being abnormally removed from the second blind hole 32, a click structure for restricting the sliding of the bolt 5 may be provided on the inner side wall of the second blind hole 32, which is the same principle and effect as the first embodiment described above, and the description thereof will be omitted.
The above two schemes are not limited to the specific structure of the bolt 5, and the bolt 5 may be in a cylindrical or conical structure, a square cylindrical structure, or other irregular shapes. Meanwhile, the shapes of the first slot 12 and the second slot are matched with the shape of the bolt 5, so that the bolt 5 can displace in the first slot 12 and the second slot.
Further, in the two solutions described above, the bolt 5 of the present embodiment 1 may have magnetism, that is, the bolt 5 has a property of being attracted by an external magnetic field, the bolt 5 is made of a magnetic material and is coated with a permanent magnet layer or is made of a material such as iron, cobalt, nickel, or an alloy thereof, and the bolt 5 is driven to move in the first slot 12 by using an external magnet that is magnetically attracted to the bolt 5 on the surface of the first member 10, so as to control the bolt 5 to move out of the second slot, and release the limiting effect of the bolt 5 on the locking member 3, so that the first connecting member 1 and the second connecting member 2 can be detached from each other. Meanwhile, the magnetic force is used for driving the bolt 5 to displace in the first slot hole 12, so that the damage to the surface of the first component 10 can be avoided, the aesthetic property of the first component 10 is ensured, and the integral structure of the connecting assembly is simplified.
Further, referring to fig. 4-5 and 21, in the case that the bolt 5 has magnetism, the bolt 5 of the embodiment 1 has a cylindrical or conical structure, the circumferential outer surface of the bolt 5 is provided with an external thread structure, and the second slot is provided with an internal thread knot in cooperation with the bolt 5. The magnetism of the bolt 5 may be specifically that the bolt 5 is provided with a magnetic element, the bolt 5 and the magnetic element may be formed into an integral piece, and the magnetic element is also fixed on the bolt 5, so that the bolt 5 has magnetism, and meanwhile, the magnetism of the bolt 5 has both an N pole and an S pole. When the first connecting piece 1 and the second connecting piece 2 are in a connecting state, the external thread structure of the bolt 5 is in threaded fit with the internal thread structure of the second slotted hole, so that the bolt 5 can be effectively prevented from abnormally moving out of the second slotted hole, and the connecting stability between the first connecting piece 1 and the second connecting piece 2 is ensured. 28-29, when the bolt 5 needs to be removed from the second slot hole, the bolt 5 is driven to rotate by adopting a rotating magnet 6 (the rotating magnet 6 also has an N pole and an S pole) on the surface of the first component 10, the bolt 5 rotates along with the rotating magnet 6 through the magnetic interaction of the rotating magnet 6, the bolt 5 converts the rotation motion of the bolt 5 into the linear motion to be removed from the second slot hole through the matching relationship between the external thread on the bolt 5 and the internal thread of the second slot hole, and the limiting effect of the bolt 5 on the locking piece 3 is released, so that the first connecting piece 1 and the second connecting piece 2 can be mutually detached.
In addition, referring to fig. 21, 28-29, the end of the bolt 5 is provided with a cross-shaped groove or a straight-line-shaped groove or an inner hexagon, and when the bolt is conveniently installed, an external tool such as a screwdriver is adopted to screw the bolt 5 into the second slot hole (the screwing direction can be set to be forward rotation) from one end of the plug-in port 123, so that the operation is more concise and effective.
Further, referring to fig. 10-13 and 25, in the case where the bolt 5 has magnetism, one end of the bolt 5 of this embodiment 1 is tapered, the outer circumferential surface of the bolt 5 is provided with an external thread structure, the bolt 5 is slidably disposed in the first slot 12, and the second slot is a tapered hole 35 provided on the surface of the locking member 3. The number of conical holes 35 can be one or more, which is adapted to the number of bolts 5. The magnetic properties of the peg 5 can be understood as: referring to fig. 12-13, the entirety of the bolt 5 may be made of a magnetic material; referring to fig. 10-11, the bolt 5 may be composed of two parts, the first part has a cone and an external thread structure, and the first part may be made of a material with no magnetism, such as plastic or metal, preferably stainless steel, and has strong corrosion resistance and long service life; the second part is a magnetic material which forms an integral structure with the first part, so that the bolt 5 is entirely magnetic.
At the same time, the bolt 5 is provided with a cross-shaped groove or a straight groove or an inner hexagon on the end surface of one end far away from the cone shape. When the bolt 5 is connected with the locking member 3, external tools such as a screwdriver are used to act on the cross-shaped groove or the straight-shaped (or inner hexagonal) groove to drive the bolt 5 to slide and rotate (the rotating direction can be set to be forward rotation), so that one end of the bolt 5 with a cone structure can extend into the conical hole 35, the bolt 5 is screwed into the locking member 3 in a self-tapping forward direction, and the matching precision is higher, so that the connection between the bolt 5 and the locking member 3 is more compact and firm.
Further, referring to fig. 12-13, the cross-sectional area of the first slot 12 is greater than the cross-sectional area of the peg 5. When the first connecting piece 1 is detached from the second connecting piece 2, the rotating magnet 6 is adopted on the surface of the first component to drive the bolt 5 to rotate (at the moment, the rotating direction is reverse), the bolt 5 reversely rotates out of the conical hole 35, so that the bolt 5 is separated from the locking piece 3, the bolt 5 is further moved out of the conical hole 35 into the first slot hole 12, at the moment, the bolt 5 falls on the inner bottom in the first slot hole 12, the central axis of the bolt 5 positioned in the first slot hole 12 is lower than the central axis of the conical hole 35, the assembly error is large, the bolt 5 is difficult to enter the conical hole 35 again under the driving of the rotating magnet (the bolt 5 is positively screwed in), and misoperation in the detaching process is prevented.
Further, referring to fig. 14-15, the bolt 5 is slidably disposed within the first slot 12, and the second slot is a tapered hole 35 disposed on the surface of the locking member; the bolt 5 comprises a first self-tapping block 53 and a first power block 54 with magnetism; the magnetic properties of the first power block 54 have both N and S poles such that the first power block 54 can be driven to rotate by the use of rotating magnets on the exterior of the first member. The end part of one end of the first self-tapping block 53 is cone-shaped, the other end of the first self-tapping block 53 is provided with a first extending arm 531, and the circumferential outer surface of the first self-tapping block 53 is provided with an external thread structure; one end of the first power block 54 is provided with a second extending arm 541, and the other end of the first power block 54 is provided with a first connecting part, wherein the first connecting part is a cross-shaped groove or a straight groove or an inner hexagon; the number of the first and second extension arms 531 and 541 may be one or two, and the first extension arm 531 is connected to the second extension arm 541. When an external tool such as a screwdriver is connected with the first connecting portion and then drives the first power block 54 to rotate (the rotation direction can be set to be forward rotation) and slide in the first slot hole 12, the first self-tapping block 53 and the first power block 54 can be driven to synchronously rotate, one cone-shaped end of the first self-tapping block 53 can be inserted into the conical hole 35, and then the first self-tapping block is screwed into the locking member in a forward direction. When the first connecting piece 1 is separated from the second connecting piece 2, the surface of the first member adopts a rotating magnet to drive the first power block 54 to rotate (the rotation direction is reverse), so as to drive the first self-tapping block 53 to reversely unscrew from the tapered hole 35, so that the bolt 5 is separated from the locking piece, and the bolt 5 is moved out of the tapered hole 35 into the first slot hole 12.
Preferably, referring to fig. 15, the cross-sectional area of the first slot 12 is greater than the cross-sectional area of the first self-tapping block 53. That is, after the first self-tapping block 53 is reversely screwed out from the tapered hole 35, the first self-tapping block 53 falls on the inner bottom of the first slot hole 12, so that the central axis of the first self-tapping block 53 located in the first slot hole 12 is lower than the central axis of the tapered hole 35, the assembly error is larger, the first self-tapping block 53 is difficult to enter the tapered hole 35 again under the driving of the rotating magnet (the first self-tapping block 53 is positively screwed in), and misoperation in the splitting process is prevented.
Further, referring to fig. 16, the bolt 5 is slidably disposed in the first slot 12, and the second slot is a tapered hole 35 disposed on the surface of the locking member; the bolt 5 includes a second self-tapping block 55, a connection block 56 having magnetism, and a second power block 57, the magnetism of the connection block 56 having both N and S poles, so that the connection block 56 can be driven to rotate by using a rotating magnet outside the first member. The end part of one end of the second self-tapping block 55 is cone-shaped, the other end of the second self-tapping block 55 is in clamping connection with the connecting block 56 (can be in a concave-convex matching connection mode), and the circumferential outer surface of the second self-tapping block 55 is provided with an external thread structure; the connecting block 56 is connected with a second power block 57 through a spring 58 at one end opposite to the connecting block 56, and the second power block 57 is provided with a second connecting part at one end far away from the spring 58; the second connecting part is a cross-shaped groove or a straight groove or an inner hexagon. When an external tool such as a screwdriver is connected with the second connecting part, the second power block 57 is driven to rotate (the rotating direction can be set to be forward rotation), and the second power block slides in the first slot hole 12 and is fixed at a specific position; the second self-tapping block 55 is driven to rotate through the connecting block 56, one end of the second self-tapping block 55 in a cone shape can be inserted into the conical hole 35, then the second self-tapping block 55 is screwed into the locking piece in a forward direction, in the screwing process, the compression deformation energy of the spring 58 is released, and the compression deformation energy of the spring 58 is utilized to generate an additional thrust force on the second self-tapping block 55, so that the second self-tapping block 55 is tightly connected with the connecting block 56 in the forward movement process of the connecting block 56, and the second self-tapping block 55 cannot be separated from the connecting block 56. When the first connecting piece 1 is separated from the second connecting piece 2, the rotating magnet is adopted on the surface of the first component to drive the connecting block 56 to rotate (the rotating direction is reversed), so as to drive the second self-tapping block 55 to reversely rotate out of the conical hole 35, so that the bolt 5 is separated from the locking piece, and the bolt 5 is moved out of the conical hole 35 into the first slot hole 12.
Preferably, the cross-sectional area of the first slot 12 is greater than the cross-sectional area of the second self-tapping block 55. That is, after the second self-tapping block 55 is reversely screwed out from the tapered hole 35, the second self-tapping block 55 falls on the bottom of the inner side of the first slot hole 12, so that the central axis of the second self-tapping block 55 positioned in the first slot hole 12 is lower than the central axis of the tapered hole 35, the assembly error is larger, the second self-tapping block 55 is difficult to enter the tapered hole 35 again under the driving of the rotating magnet (the second self-tapping block 55 is positively screwed in), and misoperation in the splitting process is prevented.
Further, the peg 5 may be non-magnetic. In both of the above-described embodiments, referring to fig. 8 to 9, the latch 5 of the present embodiment 1 is provided with a rack portion 51, and the first coupling member 1 is provided with a rotatable gear member 18, and the gear member 18 engages with the rack portion 51 to drive the latch 5 out of the second slot.

Meanwhile, the gear component 18 and the rack part 51 have a self-locking function, so that the bolt 5 can be prevented from being abnormally removed from the second slot hole. Further, the first member 10 in this embodiment needs to be provided with a hole site for a user to drive the gear component 18 to rotate, and the user controls the position of the bolt 5 in the second slot hole through the gear component 18 on the surface of the first member 10, so as to control the working state of the bolt 5 and the locking member 3 to be in a locking state or a separating state.

Specifically, the bolt 5 has a cylindrical or conical structure, and the first slot 12 of the first connecting member 1 is adapted to the bolt 5, so that the bolt 5 can be accommodated in the first slot 12 and rotate around the central axis thereof. When the external force drives the bolt 5 to rotate and the sharp corner 52 is clamped into the second slot hole, the bolt 5 plays a limiting and fastening role on the locking piece 3, and the locking piece 3 is limited to be pulled out of the inserting slot 11; when the external force drives the bolt 5 to rotate and the sharp corner 52 is moved out of the second slot, the limit action of the bolt 5 on the locking piece 3 is released, so that the first connecting piece 1 and the second connecting piece 2 can be mutually detached. Further, the first member 10 in this embodiment needs to be provided with a hole for a user to rotate the bolt 5, and the user locks or unlocks the locking member 3 by rotating the bolt 5 on the surface of the first member 10.

When the locking member 3 is inserted into the through-connection channel 21, a movement gap exists between any one of the first tooth bodies and the second tooth bodies within an allowable error range, so that the first tooth body or the second tooth body can slightly displace on the movement gap, thereby leading to that the locking member 3 can vibrate on the second connecting member 2, and the locking effect is poor. Referring to fig. 30 to 31, in order to improve the locking effect of the locking member 3 and the second connecting member 2, at least two sets of first teeth 211 are arranged in a staggered manner along the axial direction of the through-connection channel 21, and the second teeth of each set of second teeth 33 are located on the same horizontal plane along the axial direction of the through-connection channel 21, so that the first teeth of the at least two sets of first teeth 211 are located at different positions of the movement gap, and relative constraint is formed by relative dislocation between the first teeth of the at least two sets of first teeth 211, so that the movement gap between the first teeth of the at least one set of first teeth 211 and the second teeth of the at least two sets of first teeth 211 can be reduced, so that the first teeth of one set of first teeth 211 are more tightly meshed with the second teeth, and the locking effect between the locking member 3 and the second connecting member 2 is greatly improved.
Specifically, when the first tooth bodies between the two groups of first tooth portions 211 are staggered and distributed along the axial direction of the through-connection channel 21, one half of the moving gap of the first tooth bodies between the two second tooth bodies is effectively reduced, and the locking effect between the locking piece 3 and the second connecting piece 2 is improved. When the first tooth bodies among the three groups of the first tooth parts 211 are distributed in a staggered manner along the axial direction of the cross-connection channel 21, one third of the movement gap of the first tooth bodies between the two second tooth bodies is effectively reduced, and the locking effect between the locking piece 3 and the second connecting piece 2 is improved. By analogy, when the number of the first tooth bodies among the plurality of groups of the first tooth portions 211 is larger, the moving gap of the first tooth bodies between the two second tooth bodies is smaller, so that the locking effect of the locking piece 3 and the second connecting piece 2 is better.
In the same principle, in embodiment 2 of the present invention, the second tooth bodies of at least two sets of second tooth portions 33 may be staggered and distributed along the axial direction of the through-connection channel 21, and the first tooth bodies of each set of first tooth portions 211 are located on the same horizontal plane along the axial direction of the through-connection channel 21, so as to further improve the locking effect of the locking member 3 and the second connecting member 2.
In the case of satisfying the above-described locking effect for improving the locking effect between the locking member 3 and the second connecting member 2, for the convenience of manufacturing and improvement of the assembly efficiency, referring to fig. 5 to 17, 20, 22 to 25, the number of the first teeth 211 is two groups, the number of the second teeth 33 is two groups, and the two groups of the first teeth 211 are in one-to-one correspondence with the two groups of the second teeth 33; the two sets of second teeth 33 are axisymmetrically arranged about the locking member 3. The one-to-one correspondence between the two first teeth 211 and the two second teeth 33 refers to an azimuthal adaptation, so that one of the first teeth 211 and one of the second teeth 33 are engaged with each other, and the other of the first teeth 211 and the other of the second teeth 33 are engaged with each other. The two sets of second teeth 33 are axisymmetrically arranged on the locking piece 3, so that the second teeth 33 of the locking piece 3 are assembled without distinguishing the orientation, and the locking piece 3 can be inserted into the through-connection channel 21 in the forward and reverse directions.
Referring to fig. 5-17, 19-20, 22-25, to further facilitate insertion of the locking member 3 into the through-passage 21, the locking member 3 is provided with a first inclined portion 34 at one end inserted into the through-passage 21, and a second inclined portion 212 cooperatively guided with the first inclined portion 34 is provided on a side wall of an inlet 213 of the through-passage 21. Wherein the surface of the first inclined portion 34 and the surface of the second inclined portion 212 are fitted to each other, so that the locker 3 is stably inserted into the through passage 21 in a predetermined direction.
Further, referring to fig. 18, in order to prevent the plug 5 from having a resistance in the second slot hole greater than that of the external driving device (external magnet or rotating magnet 6) so that the plug 5 cannot be removed from the second slot hole, the second connector 2 of the present embodiment 2 is provided with an insertion groove 28 on the end face of the outlet 214 end of the insertion passage 21, and the insertion passage 21 is broken by forcibly opening after inserting the expanding member into the insertion groove 28 so that the first tooth body and the second tooth body cannot be normally engaged, and the second connector 2 and the locking member 3 can be relatively separated so that the first connector 1 and the second connector 2 are separated, and the locking member 3 remains in the insertion groove 11.
Further, in order to ensure that the locking member 3 only bears the acting force along the axial direction of the through-connection channel 21, the structure of the locking member 3 is matched with the structure of the through-connection channel 21, and the surface of the locking member 3 is attached to the inner side wall of the through-connection channel 21, so that the inner side wall of the through-connection channel 21 limits the radial movement of the locking member 3, and the locking effect of the locking member 3 and the second connecting member 2 is improved. In order to improve the locking effect of the locking member 3 in the through-connection channel 21, referring to fig. 20, the cross section of the locking member 3 in embodiment 2 of the present invention is square, so as to effectively limit the radial movement of the locking member 3 in the through-connection channel 21.
Example 3
Embodiment 3 of the present invention discloses a fixing structure for clamping the first connector 1 in the first arc-shaped groove 101 and the second connector 2 in the second arc-shaped groove 201 in the above embodiment 1.
The following is a specific description of the application of the fixing structure of embodiment 3 to the first connecting member 1 and the first member 10.
Referring to fig. 32 to 35, the surface 16 of the first connector is provided with a first elastic fixing portion 17, and when the first connector 1 slides in along the arc surface of the first arc groove 101, the first elastic fixing portion 17 elastically deforms and abuts against the inner sidewall 101b of the first arc groove to limit the relative movement of the first connector 1 and the first member 10. Further, according to the actual working requirements, the surface 16 of the first connecting piece is provided with a plurality of first elastic fixing parts 17 to improve the clamping effect of the first connecting piece 1 in the first arc-shaped groove 101. Preferably, in embodiment 3 of the present invention, the number of the first elastic fixing portions 17 is two, and the two first elastic fixing portions 17 are respectively disposed on two opposite surfaces of the first connecting member 1, so that the two opposite surfaces of the first connecting member 1 respectively abut against the inner side walls 101b of the first arc-shaped groove, thereby improving the clamping effect and stability of the first connecting member 1 in the first arc-shaped groove 101.
Further, referring to fig. 1-2, since the first arc-shaped groove 101 is shallow at both ends and deep in the middle, the contact area between the two ends of the surface 16 of the first connecting piece and the two ends of the inner sidewall 101b of the first arc-shaped groove is smaller, and the contact area between the central area of the surface 16 of the first connecting piece and the central area of the inner sidewall 101b of the first arc-shaped groove is larger, in order to improve the clamping effect of the first connecting piece 1in the first arc-shaped groove 101, the elastic deformation amount of the central area of the first elastic fixing portion 17 is larger than the elastic deformation amount of the two ends of the first elastic fixing portion 17, so that the elastic pretightening force of the position with the larger contact area between the first connecting piece 1 and the first arc-shaped groove 101 is larger, and the first connecting piece 1 is firmly clamped in the first arc-shaped groove 101. Meanwhile, the smaller elastic deformation quantity at the two ends of the first elastic fixing part 17 is beneficial to the first connecting piece 1 to slide into the first arc-shaped groove 101, so that the phenomenon that the first connecting piece 1 needs to be pushed by large external force due to overlarge whole friction force of the first connecting piece 1 is avoided, and the labor is saved and the operation is convenient.
Referring to fig. 32 to 34, there is shown a specific structure of the first elastic fixing portion 17 of embodiment 3 of the present invention. The first elastic fixing portion 17 includes a first arc-shaped positioning portion 171 provided on the surface 16 of the first connection member, and a first elastic member 172 provided on the first arc-shaped positioning portion 171; the first elastic member 172 may be elastically deformed and abut against the bottom of the inner sidewall 101b of the first arc-shaped groove. Accordingly, referring to fig. 1-2, the bottoms of the two inner sidewalls 101b of the first arc-shaped groove are respectively concavely provided with an arc-shaped mounting groove capable of accommodating the first arc-shaped positioning portion 171, and the arc-shaped mounting groove extends to the opening of the first arc-shaped groove 101 along the extending direction of the bottom wall 101c of the first arc-shaped groove, so that notches 101d in a T shape are formed at both ends of the opening of the first arc-shaped groove 101. When the first connector 1 slides along the arc bottom wall 101c of the first arc groove, the first arc positioning portion 171 slides into the arc mounting groove from the notch 101d, and the surface 16 of the first connector is attached to the inner side wall 101b of the first arc groove. After the installation is finished, the first elastic component 172 elastically deforms and abuts against the bottom of the inner sidewall 101b of the first arc-shaped groove, so that the first arc-shaped positioning portion 171 has a larger abutting force between the bottoms of the inner sidewall 101b of the first arc-shaped groove, so that a larger pretightening force is formed between the first connecting piece 1 and the first member 10, and the first connecting piece 1 and the first member 10 are further limited to move relatively. Meanwhile, in order to ensure that the arc edge of the first arc-shaped positioning portion 171 can be attached to the arc bottom wall 101c of the first arc-shaped groove, the radius size of the arc edge of the first arc-shaped positioning portion is larger than that of the bottom wall 101c of the first arc-shaped groove, so that after the installation is finished, the arc edge of the first arc-shaped positioning portion 171 can be attached to the edge of the bottom wall 101c of the first arc-shaped groove, the first arc-shaped positioning portion 171 is ensured to be located at the bottom of the inner side wall 101b of the first arc-shaped groove, and further, larger pretightening force exists between the first elastic component 172 and the bottom of the inner side wall 101b of the first arc-shaped groove, and the clamping effect between the first connecting piece 1 and the first member 10 is improved.
The first elastic component 172 is made of a material which can be restored after external force is removed, for example, a polymer material such as rubber or silica gel, so that the first connecting piece 1 slides into the first arc-shaped groove 101 under the action of external force, the first elastic component 172 is compressed and deformed, when the external force is removed, the bottom of the inner side wall 101b of the first arc-shaped groove is abutted against by the elastic pretightening force of the first elastic component 172, so that the first arc-shaped positioning part 171 has a larger abutting force between the bottoms of the inner side walls 101b of the first arc-shaped groove, and the friction coefficient between the first connecting piece 1 and the inner side wall 101b of the first arc-shaped groove is increased, thereby achieving the purpose of limiting the relative movement of the first connecting piece 1 and the first member 10.
The first elastic members 172 may have a continuous ridge structure or a protrusion structure provided at intervals, and the following description will explain further about the first elastic members 172 having a ridge structure or a protrusion structure, respectively.
Referring to fig. 32, the first elastic member 172 is an arc-shaped protrusion provided along an arc-shaped edge of the first arc-shaped positioning portion 171. The continuous arc-shaped convex strip structure can increase the contact area between the continuous arc-shaped convex strip structure and the inner side wall 101b of the first arc-shaped groove, so that the friction force between the first connecting piece 1 and the first arc-shaped groove 101 is larger, and the clamping effect of the first connecting piece 1 on the first arc-shaped groove 101 is improved.
Referring to fig. 33-34, the first resilient member 172 is a resilient protrusion. When the first elastic component 172 is an elastic protrusion, in order to ensure that the first elastic component 172 provides a sufficient elastic pretightening force, the number of the elastic protrusions is multiple, the elastic protrusions are arranged at intervals along the direction where the arc edge of the first arc positioning portion 171 is located, and the spacing between any two adjacent elastic protrusions may be the same or different, so that the first elastic fixing portion 17 forms a uniform and balanced pretightening force on the first member 10, and the clamping effect of the first connecting piece 1 in the first arc groove 101 is improved. Further, referring to fig. 32, the elastic protrusion is arc-shaped, and extends in a direction along which the arc edge of the first arc-shaped positioning portion 171 is located, so as to ensure an elastic pre-tightening force between the elastic protrusion and the first arc-shaped groove 101. Further, if the first member 10 is made of cork or other elastic material, when the first connector 1 is accommodated in the first arc-shaped groove 101, the inner sidewall 101b of the first arc-shaped groove can be elastically deformed to increase the friction between the first connector 1 and the inner sidewall 101b of the first arc-shaped groove, so that the elastic force of the elastic protrusion can be reduced, or the elastic force of the elastic protrusion can be smaller than the elastic force of the first member 10. Further, the elastic protrusions are provided with the rolling spherical beads, and the arrangement of the spherical beads further avoids the fact that the first connecting piece 1 needs to be pushed into by large external force due to overlarge friction force of the whole first connecting piece 1, so that labor is saved, and convenience is brought.
In some embodiments, the material of the first arc-shaped positioning portion 171 is the same as that of the first connecting member 1, for example, a thermosetting plastic material, the first arc-shaped positioning portion 171 and the first connecting member 1 may be formed into a single piece by injection molding, and the first elastic member 172 is provided on the first arc-shaped positioning portion 171 by gluing or other means. In other embodiments, the material of the first arc-shaped positioning portion 171 and the first elastic member 172 is the same as that of the first connecting piece 1, and the first arc-shaped positioning portion 171, the first elastic member 172 and the first connecting piece 1 are formed into a single piece by injection molding, so that the structure is more firm.
Referring to fig. 35, another specific structure of the first elastic fixing portion 17 according to embodiment 3 of the present invention is shown. The first elastic fixing portion 17 is an elastic convex strip in a wave shape. The elastic protruding strips extend along the direction of the arc edge of the first connecting piece 1, so that the contact area between the elastic protruding strips and the inner side wall 101b of the first arc groove is increased, and the first connecting piece 1 is clamped in the first arc groove 101 more firmly. Meanwhile, when the elastic raised strips in irregular shapes are elastically deformed, the contact area between the elastic raised strips and the first arc-shaped groove 101 is larger, so that the pretightening force of the first connecting piece 1 in the first arc-shaped groove 101 is larger, and the first connecting piece 1 can be firmly clamped in the first arc-shaped groove 101. The first elastic fixing portion 17, which is wavy, may be formed as one piece with the first connecting member 1, and may be fixed to the surface 16 of the first connecting member by gluing or other means.
In addition, the fixing structure of this embodiment 3 is applied to the second connecting piece 2 and the second member 20 and the above fixing structure is applied to the first connecting piece 1 and the first member 10 in the same structure and principle, that is, the surface 26 of the second connecting piece is provided with the second elastic fixing portion 27, and when the second connecting piece 2 slides along the arc surface of the second arc groove 201, the second elastic fixing portion 27 is elastically deformed and abuts against the inner sidewall 201b of the second arc groove, so as to limit the relative movement of the second connecting piece 2 relative to the second member 20. Therefore, the specific structure of the second elastic fixing portion 27 is not described in this embodiment 3, and a person skilled in the art can determine the structure of the second elastic fixing portion 27 with reference to the specific structure of the first elastic fixing portion 17 on the first connector 1.
