Abstract

A locking module, a clamping apparatus, an electronic device holder, and a device. The locking module (10, 10') comprises a housing (1, 1') and a transmission structure (2, 2'). An accommodating cavity (11, 11') is formed inside the housing. The transmission structure comprises a gear shaft (21), an abutting component (22), and an elastic component (23) which are arranged in the accommodating cavity. When the abutting component abuts against the gear shaft, the housing can only drive the gear shaft to rotate in an abutting direction, and when the housing rotates in a non-abutting direction, the housing idles relative to the gear shaft. The transmission structure may also consist of a ratchet wheel (210), a locking assembly (220), a first limiting assembly (230), and a second limiting assembly (240). When the first limiting assembly or the second limiting assembly abuts against the ratchet wheel, the housing drives, in a first direction or a second direction, a nut (33) to rotate, and when the housing rotates in the other direction, the housing idles relative to the nut. The locking module solves the technical problem of poor anti-theft effect of existing locking modules.

[0002] In daily life and industrial production, threaded fasteners are widely used in products such as doors and windows, vehicles, and machinery due to their simple structure and reliable connection. However, with the development of technology and changes in the social environment, higher requirements have been placed on the safety performance of threaded fasteners. Traditional threaded fasteners, such as bolts and nuts, while providing good fastening effects, have significant shortcomings in terms of theft prevention. Criminals can easily remove these fasteners through simple operations, thereby stealing or damaging related equipment. Summary of the Invention

[0013] Another solution to the technical problem of the present invention is to provide a clamping device, including a fixed clamp, a movable clamp, and the aforementioned locking module. The fixed clamp and the movable clamp are rotatably connected. The locking module is movably connected to the movable clamp after passing through one side of the fixed clamp.

[0017] Another solution to the technical problem of the present invention is an electronic device bracket for placing electronic devices, the electronic device bracket including the aforementioned clamping device.

[0018] Another solution to the technical problem of the present invention is to provide a device with anti-theft function, including the above-mentioned locking module.

[0019] Compared with the prior art, the locking module, clamping device, electronic device bracket and equipment of the present invention have the following advantages:

[0020] 1. In the locking module provided in the embodiments of the present invention, the elastic component enables the abutting component to abut against the gear shaft in a specific direction. Thus, when the abutting component rotates in the abutting direction, it drives the gear shaft to rotate synchronously through its abutting engagement with the gear shaft. When the abutting component rotates in the non-abutting direction, the gear shaft drives the abutting component to deflect, thereby causing the abutting component to slide along the outer circumference of the gear shaft. The abutting component rotates freely relative to the gear shaft, that is, the abutting component cannot drive the gear shaft to rotate in the non-abutting direction.

[0021] Alternatively, by setting a ratchet structure on the circumferential outer surface of the nut, the rotation of the nut can be restricted by a transmission structure after the nut is tightened. The transmission structure can only drive the ratchet to rotate in a specific direction, so that the nut can only rotate in a specific direction. This design can prevent outsiders from easily unscrewing the nut and then stealing or damaging related equipment, thus avoiding property loss.

[0022] This design prevents outsiders from unscrewing the locking module from the external device through the casing, thereby preventing theft or damage to the device and causing property loss to the user.

[0023] 2. In the locking module provided by the embodiments of the present invention, the first snap-fit ​​structure and the second snap-fit ​​structure abut against the gear shaft in different directions, so that when different snap-fit ​​structures cooperate with the gear shaft, the gear shaft is driven to rotate in different directions, and cannot rotate in the opposite direction. This realizes that the fastener and the external device have two cooperation modes: locking and detachable. While ensuring the good anti-theft effect of the locking module, it also allows the locking module to be removed from the relevant device when necessary.

[0024] Furthermore, under the action of the elastic component, the abutting component keeps the first or second locking structure engaged with the gear shaft, preventing the abutting component from disengaging from the gear shaft under external force, thus preventing the abutting component from driving the gear shaft to rotate. Secondly, the elastic component and the abutting component work together elastically, allowing the abutting component to return to the abutting state with the gear shaft after it has idled relative to the gear shaft, so that the abutting component can continue to drive the gear shaft to rotate.

[0025] 3. In the locking module provided in the embodiments of the present invention, the limiting post is housed in the first limiting hole that communicates with the outside. The user can operate the limiting post through the first limiting hole to control the first or second snap-fit ​​structure to cooperate with the gear shaft, so that the supporting component can drive the gear shaft to rotate in a preset direction, thereby realizing the disassembly or locking of the fastener. When the limiting post rotates to abut against the first limiting hole, the elastic component just cooperates with the first or second limiting groove. Through this design, the user can quickly and accurately rotate the supporting component to the state of cooperation with the elastic component, improving the user experience.

[0026] The second limiting hole restricts the horizontal and vertical movement of the gear shaft, allowing it to rotate only along a predetermined central axis. This ensures that the supporting component remains in contact with the gear shaft during rotation, improving the stability of the engagement between the supporting component and the gear shaft. The fastener is threaded onto the gear shaft, so that when the gear shaft rotates, it drives the fastener to rotate, allowing the exposed portion of the fastener in the hollow structure to be locked or detached from external equipment.

[0027] 4. In the locking module provided in the embodiments of the present invention, the connection between the fastener and the gear shaft is ensured by the cooperation of the first limiting structure and the second limiting structure, so as to avoid the fastener from disengaging from the gear shaft due to excessive rotation of the gear shaft; the elastic component is fixed relative to the housing by the third limiting groove, so that when the elastic component cooperates with the abutting component, the abutting component can also maintain the corresponding positioning state, so that it can better drive the gear shaft to rotate.

[0028] 5. In the locking module provided in the embodiments of the present invention, the ratchet is driven by the first or second limiting member when the housing structure is rotated through the meshing state between the ratchet and the first or second limiting member, so that the nut rotates in a clockwise or counterclockwise direction, thereby locking or unlocking the nut. The ratchet structure ensures that the nut has a good anti-theft function.

[0029] 6. In the locking module provided in this embodiment of the invention, the engagement between the abutment and the ratchet is achieved through the cooperation between the abutment, the elastic element and the rotating shaft. One end of the rotating shaft on the limiting member serves as a rotating section, driving the abutment to rotate relative to the rotating shaft. One end of the abutment serves as a working section. The elastic element is located on the side away from the locking assembly, which can ensure that the ratchet can only rotate in a specific direction in different locking modes. This ensures that after the nut is locked by rotating in one direction, it cannot be disassembled by rotating in another direction, thus improving the user experience of the locking module.

[0030] 7. In the locking module provided in the embodiments of the present invention, when the housing structure rotates in a specific direction, since the rotating shaft is fixedly set inside the housing structure, the abutting surface of the abutting member away from the rotating shaft can abut against the ratchet, thereby driving the nut to rotate; since the elastic member is movable and deformable, the abutting surface of the abutting member away from the elastic member cannot drive the nut to rotate, which will cause the housing structure to rotate freely relative to the nut.

[0031] By rotating the locking assembly, the holding member can be controlled to engage with the ratchet. At this time, the ratchet contacts the holding surface on the holding member. When the nut can rotate in a specific direction, the shaft pushes the holding surface on the holding member away from the shaft to contact the ratchet, thereby driving the ratchet to rotate. The two holding members can make the nut rotate in opposite directions respectively.

[0032] 8. In the locking module provided in this embodiment of the invention, when the locking assembly rotates, the first rotating member drives the second rotating member to rotate, and the second rotating member abuts against one of the abutting members, causing the abutting member on the other side to engage with the ratchet. By providing a boss on the side of the first rotating member and providing a through groove on the housing structure to expose the boss, the boss slides in the through groove to abut against the inner sidewall of the through groove, thereby achieving a limiting fit between the locking assembly and the housing structure. In addition, the first rotating member and the boss are exposed after passing through the through groove, allowing the user to know the current locking mode of the locking module.

[0033] 9. In the locking module provided in the embodiments of the present invention, the groove provided on the inner wall of the housing and the through hole provided on the bottom plate can ensure the limiting of the rotating shaft when the housing structure rotates, thereby ensuring that the supporting member only rotates relative to the rotating shaft. Through this design, on the one hand, it can protect the limiting component and extend the service life of the locking module, and on the other hand, it can improve the stability of the limiting component.

[0034] Secondly, the locking module also ensures the overall structural stability of the ratchet and nut by restricting their movement in the horizontal and vertical directions, ensuring the stability of the ratchet and nut's fixed connection with the housing structure, so that the limiting component can smoothly engage with the ratchet and drive the ratchet and nut to rotate together when the housing rotates in a specific direction.

[0035] 10. An embodiment of the present invention provides a clamping device, which includes a clamping module, a support module and a locking module connected in sequence. The locking module is used to lock the clamping module after it is connected to the support module; or it includes a fixed clamp and a movable clamp that are rotatably connected. The fixed clamp and the movable clamp cooperate to clamp the clamping device on a vehicle, the edge of a desktop, the top of a television set, etc., and the relative position of the clamp and the movable clamp is fixed by the locking module, thereby fixing the clamping device on the relevant equipment.

[0036] It should be noted that the clamping device has the same beneficial effects as the locking module described in any of the preceding items, and will not be repeated here.

[0037] 11. In the clamping device provided in the embodiments of the present invention, the movable connecting section is rotatably connected to the fixed chuck, thereby realizing the clamping size between the movable chuck and the fixed chuck to adapt to different sizes of the equipment to be clamped; one end of the housing provided in the transmission structure is located at the end of the fixed chuck away from the movable chuck, and the fastener passes through the fixed chuck and connects to the movable chuck. The housing drives the fastener to rotate, thereby driving the movable chuck to rotate relative to the fixed chuck to clamp the external equipment.

[0038] 12. In the clamping device provided in the embodiments of the present invention, the fixed chuck is provided with a strip-shaped clearance hole in the length direction to movably cooperate with the fastener. It can be understood that when the movable chuck rotates relative to the fixed chuck, the corresponding position of the connection point between the movable chuck and the fastener relative to the fixed chuck will also change, thereby causing the fastener on it to be displaced. Through the design of the clearance hole, the fastener has room to move when the movable chuck rotates, avoiding the rotation of the movable chuck due to the restricted movement of the fastener.

[0039] Specifically, the movable chuck and the fixed chuck are rotatably connected by a rotating rod, allowing the movable chuck to rotate relative to the fixed chuck to adjust the size of the clamping opening between them. This enables the clamping device to be clamped onto equipment of different sizes, improving its applicability. An elastic element fitted on the rotating rod provides rotational tension to the movable chuck, allowing the fixed and movable chucks to maintain their current clamping state.

[0040] 13. In the clamping device provided in the embodiments of the present invention, the first connector and the second connector are a ball head bracket and a threaded bracket, respectively, and the ball head bracket can be engaged with the threaded bracket; since the outer circumferential surface of the second connector is provided with a second external thread and the inner circumferential surface of the nut is provided with a second internal thread, that is, the nut and the second connector are threadedly connected, when the ratchet structure rotates, the nut can lock or disassemble the second connector, thereby locking and fixing the first connector, so that the first connector cannot be separated from the second connector, extending the service life of the clamping device and improving the user experience.

[0041] 14. The present invention also provides an electronic device bracket for placing electronic devices, the electronic device bracket including the above-mentioned clamping device.

[0042] It should be noted that the electronic device bracket of the present invention has the same beneficial effects as the clamping device described above, and will not be repeated here.

[0043] 15. This invention also provides a device with anti-theft function, the device including the locking module described above.

[0044] It should be noted that the device in this embodiment of the invention has the same beneficial effects as the locking module described above, and will not be repeated here. Attached Figure Description

[0069] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0071] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0074] Please refer to Figures 4-7. This embodiment of the invention provides a locking module 10, including a housing 1, a transmission structure 2, and a fastener 3. The housing 1 has a receiving cavity 11 inside. The transmission structure 2 includes a gear shaft 21, a supporting member 22, and an elastic member 23 disposed in the receiving cavity 11. The gear shaft 21 and the supporting member 22 are rotatably engaged with the housing 1. The supporting member 22 is engaged with the gear shaft 21 through the elastic member 23. When the supporting member 22 supports the gear shaft 21, the housing 1 can only drive the gear shaft 21 to rotate in the supporting direction. When the housing 1 rotates in the non-supporting direction, the housing 1 rotates freely relative to the gear shaft 21. One of the supporting direction and the non-supporting direction is clockwise, and the other is counterclockwise. One end of the fastener 3 is connected to the gear shaft 21, and the other end extends outward from the receiving cavity 11.

[0075] Specifically, the maximum rotation radius of the supporting component 22 is greater than the minimum distance from the rotation axis of the supporting component 22 to the outer circumferential surface of the gear shaft 21. Therefore, when the supporting component 22 rotates in the supporting direction, the supporting component 22 is subjected to the force of the gear shaft 21, thereby locking with the gear shaft 21, so that the supporting component 22 can smoothly drive the gear shaft 21 to rotate. However, when the supporting component 22 rotates in the non-supporting reverse direction, the supporting component 22 disengages from the gear shaft 21 under the action of the gear shaft 21, so that the supporting component 22 cannot drive the gear shaft 21 to rotate in that direction.

[0076] It should be noted that the abutting direction in this embodiment refers to the direction of rotation from the line connecting the rotation axis of the gear shaft 21 and the abutting component 22 to the position where the gear shaft 21 and the abutting component 22 abut; the non-abutting direction refers to the direction opposite to the abutting direction.

[0077] Understandably, the elastic member 23 enables the abutting member 22 to engage with the gear shaft 21 in a specific direction. Thus, when the abutting member 22 rotates in the abutting direction, it drives the gear shaft 21 to rotate synchronously through its engagement with the gear shaft 21. When the abutting member 22 rotates in the non-abutting direction, the gear shaft 21 drives the abutting member 22 to deflect, causing the abutting member 22 to slide along the outer circumference of the gear shaft 21. The abutting member 22 rotates freely relative to the gear shaft 21, meaning that the abutting member 22 cannot drive the gear shaft 21 to rotate in the non-abutting direction.

[0078] This design prevents outsiders from unscrewing the locking module 10 from the external device through the housing 1, thereby preventing theft or damage to the device and causing property loss to the user.

[0079] Optionally, the fastener 3 can be a bolt, screw, stud, or other mechanical connection structure that achieves fastening or disassembly by rotation, without much restriction.

[0080] Specifically, the locking module 10 provided in this embodiment is used for locking threaded fastening devices or rotating mechanical structures. Specific application scenarios include, but are not limited to, clamping devices, door and window fixing, mechanical equipment installation, and fixing of wheels and seats in vehicles.

[0081] Furthermore, please refer to Figure 8 as well. The two ends of the supporting component 22 along the length direction are respectively provided with a first snap-fit ​​structure 221 and a second snap-fit ​​structure 222. The first snap-fit ​​structure 221 and the second snap-fit ​​structure 222 abut against the gear shaft 21 in different directions.

[0082] It should be noted that when the first locking structure 221 and the second locking structure 222 abut against the gear shaft 21, their contact points are located on both sides of the line connecting the gear shaft 21 and the rotating shaft of the abutting component 22. That is, when the first locking structure 221 abuts against the gear shaft 21, the abutting direction defined in this embodiment is opposite to the abutting direction when the second locking structure 222 abuts against the gear shaft 21.

[0083] As one possible implementation, the first snap-fit ​​structure 221 and the second snap-fit ​​structure 222 are tooth-shaped structures that can mesh with the gear shaft 21.

[0084] Understandably, the first snap-fit ​​structure 221 and the second snap-fit ​​structure 222 abut against the gear shaft 21 in different directions, so that when different snap-fit ​​structures cooperate with the gear shaft 21, the gear shaft 21 can be driven to rotate in different directions, and it cannot rotate in the opposite direction. This enables the fastener 3 to have both locking and detachable cooperation modes with the external device. While ensuring the good anti-theft effect of the locking module 10, it also allows the locking module 10 to be removed from the relevant device when necessary.

[0085] Furthermore, the supporting member 22 is provided with a first limiting groove 223 and a second limiting groove 224 on the side near the elastic member 23. When the first limiting groove 223 cooperates with the elastic member 23, the first snap-fit ​​structure 221 abuts against the gear shaft 21. When the second limiting groove 224 cooperates with the elastic member 23, the second snap-fit ​​structure 222 abuts against the gear shaft 21.

[0086] Optionally, the abutting ends of the elastic member 23 and the abutting member 22 are spherical.

[0087] It should be noted that the first limiting groove 223 and the second limiting groove 224 are arranged side by side on the side of the supporting member 22 near the elastic member 23. When the first limiting groove 223 cooperates with the elastic member 23, the elastic member 23 abuts against the end of the first limiting groove 223 away from the second limiting groove 224, and there is a gap between the elastic member 23 and the end of the first limiting groove 223 near the second limiting groove 224.

[0088] Understandably, when the supporting member 22 rotates in the supporting direction, under the action of the gear shaft 21, the end of the first limiting groove 223 of the supporting member 22 away from the second limiting groove 224 tends to rotate towards the elastic member 23. This design allows the supporting member 22 to drive the gear shaft 21 to rotate more stably. Conversely, when the supporting member 22 rotates in the non-supporting direction, under the action of the gear shaft 21, the end of the first limiting groove 223 of the supporting member 22 near the second limiting groove 224 rotates towards the elastic member 23 to disengage the supporting member 22 from the gear shaft 21. This design allows the supporting member 22 to rotate more smoothly to disengage the supporting member 22 from the gear shaft 21.

[0089] In one embodiment, when the second limiting groove 224 cooperates with the elastic member 23, the elastic member 23 abuts against the end of the second limiting groove 224 away from the first limiting groove 223, and there is a gap between the elastic member 23 and the end of the second limiting groove 224 close to the first limiting groove 223.

[0090] Understandably, the way the second limiting groove 224 and the elastic component 23 cooperate is the same as the way the first limiting groove 223 and the elastic component 23 cooperate, and the corresponding beneficial effects are also the same.

[0091] Understandably, the abutting member 22, under the action of the elastic member 23, keeps the first locking structure 221 or the second locking structure 222 engaged with the gear shaft 21, preventing the abutting member 22 from disengaging from the gear shaft 21 under the influence of external force, thus preventing the abutting member 22 from driving the gear shaft 21 to rotate. Secondly, the elastic member 23 and the abutting member 22 are elastically engaged, so that after the abutting member 22 rotates relative to the gear shaft 21, it can return to the abutting state with the gear shaft 21, thereby allowing the abutting member 22 to continue driving the gear shaft 21 to rotate.

[0092] Further, please refer to Figures 4 and 6 again. The upper end of the housing 1 is provided with a first limiting hole 12 that communicates with the outside. The upper end face of the supporting component 22 is provided with a limiting post 225 that rotates and cooperates with the first limiting hole 12. When the limiting post 225 rotates to abut against the first limiting hole 12, the elastic component 23 cooperates with the first limiting groove 223 or the second limiting groove 224.

[0093] Optionally, the supporting component 22 and the limiting post 225 are integrally formed.

[0094] As a feasible implementation method, the first limiting hole 12 and the limiting post 225 are matched in shape and are not circular. The rotatable angle between the limiting post 225 and the first limiting hole 12 is less than 360 degrees. That is, when the limiting post 225 rotates clockwise or counterclockwise in the first limiting hole 12 to a certain angle, it will abut against the inner wall of the first limiting hole 12 and cannot continue to rotate.

[0095] Specifically, when the limiting post 225 rotates clockwise to abut against the first limiting hole 12, the elastic component 23 is just in a state of abutting and cooperating with the first limiting groove 223, thereby making the first snap-fit ​​structure 221 mesh with the gear shaft 21, and thus enabling the abutting component 22 to stably drive the gear shaft 21 to rotate in a preset direction.

[0096] It should be understood that when the limiting post 225 rotates counterclockwise to abut against the first limiting hole 12, the elastic component 23 is just in a state of abutting and cooperating with the second limiting groove 224, so that the second snap-fit ​​structure 222 meshes with the gear shaft 21, and the abutting component 22 can stably drive the gear shaft 21 to rotate in another preset direction.

[0097] With this design, even without observing the rotation state of the supporting component 22, the user can precisely control the rotation angle of the supporting component 22, so that the supporting component 22 can mesh with the gear shaft 21, thereby smoothly driving the rotation of the gear shaft 21.

[0098] Specifically, the locking module 10 is in disassembly mode or anti-theft mode by the opposing forces between the limiting post 225 and the first limiting hole 12 in different directions.

[0099] Understandably, the limiting post 225 is partially housed in the first limiting hole 12 that communicates with the outside. The user can operate the limiting post 225 through the first limiting hole 12 to control the first locking structure 221 or the second locking structure 222 to cooperate with the gear shaft 21, so that the supporting component 22 can drive the gear shaft 21 to rotate in a preset direction, thereby realizing the disassembly or locking of the fastener 3.

[0100] Specifically, when the limiting post 225 rotates to abut against the first limiting hole 12, the elastic component 23 just matches the first limiting groove 223 or the second limiting groove 224. This design allows the user to quickly and accurately rotate the abutting component 22 to match the elastic component 23, improving the user experience.

[0101] Furthermore, the upper surface of the first limiting hole 12 is higher than the upper surface of the limiting post 225, and the upper surface of the limiting post 225 is provided with a polygonal first locking groove 226.

[0102] It should be noted that the upper surface of the first limiting hole 12 is higher than the upper surface of the limiting post 225, that is, the limiting post 225 is completely contained within the first limiting hole 12 and has no part exposed to the outside.

[0103] This design prevents outsiders from operating the limiting post 225 without damaging the housing 1, thereby switching the disassembly mode or anti-theft mode of the locking module 10 and improving the anti-theft effect of the locking module 10.

[0104] It should be further noted that the first locking groove 226 can be a polygonal protrusion or groove provided on the upper surface of the limiting post 225.

[0105] Optionally, the first locking groove 226 can be set as a triangle, quadrilateral, hexagon, or other irregular shape, which can be set according to the actual situation.

[0106] As a feasible implementation, the first locking groove 226 is a hexagonal groove that cooperates with an Allen wrench. That is, the first locking groove 226 can only be operated with an Allen wrench of the corresponding type, so that the supporting component 22 can be rotated by a corresponding angle, so that the locking module 10 is in disassembly mode or anti-theft mode.

[0107] Understandably, the first locking groove 226 on the limiting post 225 is polygonal, which requires a specific tool that is adapted to the shape of the first locking groove 226 to engage with the first locking groove 226 to rotate the abutment component 22, thereby putting the locking module 10 into disassembly mode or anti-theft mode.

[0108] This design effectively prevents outsiders from switching the disassembly mode or anti-theft mode of the locking module 10 by rotating the limit post 225 without using tools or with tools readily available, thus ensuring a good anti-theft effect.

[0109] Furthermore, please refer to Figures 9 and 10 together. At least one end of the housing 1 along the axial direction of the gear shaft 21 is provided with a second limiting hole 13, and the gear shaft 21 is rotatably engaged with the housing 1 through the second limiting hole 13.

[0110] As a feasible implementation, the housing 1 is provided with a second limiting hole 13 communicating with the outside at both ends along the axial direction of the gear shaft 21. The gear shaft 21 includes a gear part 214 and a rotating part 215 connected together. The rotating part 215 is located at both ends of the axial direction of the gear part 214, and the second limiting hole 13 is rotatably engaged with the rotating part 215.

[0111] Specifically, the size of the second limiting hole 13 is adapted to the rotating part 215, the rotating part 215 is sleeved in the second limiting hole 13, and the end face of the gear part 214 abuts against the end face of the second limiting hole 13 near the gear part 214.

[0112] The design of the second limiting hole 13 restricts the movement of the gear shaft 21 in the horizontal and vertical directions, so that the gear shaft 21 can only rotate along the predetermined central axis, thereby ensuring that the supporting component 22 can always maintain the supporting state with the gear shaft 21 when rotating, and improving the stability of the cooperation between the supporting component 22 and the gear shaft 21.

[0113] In a specific embodiment, a baffle 15 is provided on the second limiting hole 13 located at the end of the housing 1 away from the fastener 3. The baffle 15 is used to cover the second limiting hole 13, thereby preventing the fastener 3 from separating from the gear shaft 21 from the second limiting hole 13.

[0114] Optionally, the second limiting hole 13 on the end of the housing 1 away from the fastener 3 can be configured not to communicate with the outside.

[0115] As another feasible implementation, the housing 1 is provided with a second limiting hole 13 that communicates with the outside at one end near the fastener 3. The gear shaft 21 is a rotating part 215 at one end near the second limiting hole 13 and a gear part 214 at the other end away from the second limiting hole 13. The fastener 3 extends outward from the second limiting hole 13.

[0116] Furthermore, please refer to Figures 11 and 12 together. The gear shaft 21 has a hollow structure 211. The hollow structure 211 is at least partially provided with a first internal thread 213. The fastener 3 is provided with a first external thread 31 in the length direction that mates with the first internal thread 213.

[0117] It should be noted that the fastener 3 passes through the gear shaft 21 through the hollow structure 211 and is threaded to the gear shaft 21 on the inner wall of the hollow structure 211. This allows the fastener 3 to rotate when the gear shaft 21 rotates, and the part of the fastener 3 exposed in the hollow structure 211 can be locked or detached from the external equipment.

[0118] Furthermore, the fastener 3 is partially housed within the hollow structure 211, and the inner wall of the hollow structure 211 is provided with a first limiting structure 212. One end of the fastener 3 housed within the hollow structure 211 is provided with a second limiting structure 32 that cooperates with the first limiting structure 212.

[0119] As a feasible implementation, the first limiting structure 212 is an annular protrusion on the inner wall of the hollow structure 211, and the first internal thread 213 is provided on the inner wall of the first limiting structure 212. The fastener 3 is threadedly engaged with the first internal thread 213 on the first limiting structure 212 through the first external thread 31 on it, thereby connecting the fastener 3 with the gear shaft 21.

[0120] The fastener 3 is housed in the hollow structure 211. One end of the structure is provided with a second limiting structure 32. When the fastener 3 rotates relative to the gear shaft 21, the second limiting structure 32 moves closer to or further away from the first limiting structure 212. When the fastener 3 rotates to the point where the second limiting structure 32 contacts the first limiting structure 212, the first limiting structure 212 restricts the fastener 3 from continuing to rotate in that direction, thus preventing the gear shaft 21 from rotating excessively and causing the fastener 3 to detach from the gear shaft 21.

[0121] Furthermore, the inner wall of the housing 1 is provided with a third limiting groove 14, and the elastic component 23 is fixedly engaged with the housing 1 through the third limiting groove 14.

[0122] Understandably, the elastic member 23 is partially housed in the third limiting groove 14. The movement of the elastic member 23 within the housing 1 is restricted by the third limiting groove 14, so that the elastic member 23 is relatively fixed to the housing 1. Thus, when the elastic member 23 cooperates with the abutting member 22, the abutting member 22 can also maintain the corresponding positioning state, so that it can better drive the gear shaft 21 to rotate.

[0123] Optionally, the elastic member 23 is fixedly mounted on the housing 1.

[0124] Please refer to Figures 14, 15, and 18. In some embodiments, the locking module 10' includes a housing 1', a nut 33, and a transmission structure 2'. The housing 1' has a hollow channel 16 for fixing the nut 33. The interior of the housing 1' has a receiving cavity 11'. The transmission structure 2' includes a ratchet 210, a locking assembly 220, a first limiting assembly 230, and a second limiting assembly 240 disposed in the receiving cavity 11'. The ratchet 210 is disposed on the circumferential outer surface of the nut 33, and the locking assembly 220 is located at the first limiting assembly 240. Between the positioning component 230 and the second limiting component 240; the nut 33 is rotatably engaged with the housing 1', and the locking component 220 drives the first limiting component 230 or the second limiting component 240 to elastically abut against the ratchet 210; when the first limiting component 230 abuts against the ratchet 210, the housing 1' drives the nut 33 to rotate in the first direction and rotates freely relative to the nut 33 in the second direction; when the second limiting component 240 abuts against the ratchet 210, the housing 1' drives the nut 33 to rotate in the second direction and rotates freely relative to the nut 33 in the first direction.

[0125] The first direction and the second direction are respectively clockwise and counterclockwise.

[0126] The locking module 10' provided by this invention has a ratchet structure set on the circumferential outer surface of the nut 33, and the ratchet 210 is integrally formed with the nut 33. After the nut 33 is tightened, the rotation of the nut 33 can be restricted by the transmission structure 2'. The transmission structure 2' can only drive the ratchet 210 to rotate in a specific direction, so that the nut 33 can only rotate in a specific direction. Through this design, the technical problem that the existing locking modules do not have anti-theft function or have poor anti-theft effect is solved, and the nut 33 is prevented from being easily unscrewed by outsiders, thereby stealing or damaging related equipment and causing property loss.

[0127] Specifically, the locking module 10' is based on the nut 33, and the transmission structure 2' enables a detachable connection between the nut 33 and the external structure. The detachable connection is a threaded connection. The nut 33 can be fixedly placed on the housing 1'. The receiving cavity 11' inside the housing 1' houses the ratchet 210, locking component 220, first limiting component 230 and second limiting component 240 of the transmission structure 2'. By setting the housing 1', the various components of the transmission structure 2' can be protected.

[0128] In particular, the adjustment end of the locking component 220 is located inside the outer surface of the housing 1' and cannot be adjusted by ordinary unlocking tools (such as wrenches, screwdrivers, etc.). It requires a specific polygonal wrench for adjustment. This design can prevent others from arbitrarily adjusting the locking component 220 and improve the anti-theft performance of the locking module 10'.

[0129] Understandably, the second internal thread of the nut 33 is located in the hollow channel 16, and both ends of the nut 33 are fixed by the housing 1'. The ratchet 210 is disposed on the circumferential outer surface of the nut 33, and the locking assembly 220 drives the first limiting assembly 230 or the second limiting assembly 240 to elastically abut against the ratchet 210. Since the first limiting assembly 230 and the second limiting assembly 240 are respectively located on both sides of the locking assembly 220, when the locking assembly 220 drives the first limiting assembly 230 to elastically abut against the ratchet 210, the locking assembly 220 abuts against the second limiting assembly 240; when the locking assembly 220 drives the second limiting assembly 240 to elastically abut against the ratchet 210, the locking assembly 220 abuts against the first limiting assembly 230.

[0130] It should be noted that the nut 33 is rotatably engaged with the housing 1'. When the first limiting component 230 or the second limiting component 240 elastically abuts against the ratchet 210, a clockwise or counterclockwise force is applied to rotate the housing 1' in order to drive the nut 33 to rotate. It can be understood that since the ratchet 210 is abutted by the first limiting component 230 or the second limiting component 240 applying an elastic force, when the rotation direction of the housing 1 corresponds to the direction of the applied elastic force, the first limiting component or the second limiting component will compress the elastic structure, making the first limiting component 230 or the second limiting component 240 unable to drive the ratchet 210 to rotate, and thus unable to rotate the nut 33.

[0131] Furthermore, when the first limiting component 230 abuts against the ratchet 210, the housing 1' can only drive the nut 33 to rotate in the first direction. When the housing 1' rotates in the second direction, the housing 1' rotates freely relative to the nut 33. When the second limiting component 240 abuts against the ratchet 210, the housing 1' can only drive the nut 33 to rotate in the second direction. When the housing 1' rotates in the first direction, the housing 1' rotates freely relative to the nut 33. The first direction and the second direction are clockwise and counterclockwise, respectively.

[0132] In the embodiments of the present invention, the first direction is clockwise and the second direction is counterclockwise. When the first limiting component 230 abuts against the ratchet 210, the housing 1' can only drive the nut 33 to rotate in the clockwise direction. When the housing 1' rotates in the counterclockwise direction, the housing 1' will spin freely relative to the nut 33. Conversely, when the first limiting component 230 abuts against the ratchet 210, when the second limiting component 240 abuts against the ratchet 210, the housing 1' can only drive the nut 33 to rotate in the counterclockwise direction. When the housing 1' rotates in the clockwise direction, the housing 1' will spin freely relative to the nut 33.

[0133] In some embodiments, the first limiting component 230 includes a first limiting member 2310 and a first elastic member 2320, and the second limiting component 240 includes a second limiting member 2410 and a second elastic member 2420; the first limiting member 2310 is rotatable relative to the housing 1', one end of the first elastic member 2320 abuts against the inner sidewall of the housing 1', and the other end contacts the first limiting member 2310; the second limiting member 2410 is rotatable relative to the housing 1', one end of the second elastic member 2420 abuts against the inner sidewall of the housing 1', and the other end contacts the second limiting member 2410.

[0134] In embodiments of the present invention, the locking assembly 220 can rotate relative to the housing 1' to abut against the first limiting member 2310 or the second limiting member 2410, and respectively make the second limiting member 2410 or the first limiting member 2310 engage with the ratchet 210.

[0135] The locking module 10' provided by the present invention, through the meshing state between the ratchet 210 and the first limiting member 2310 or the second limiting member 2410, when the housing 1' is rotated, the ratchet 210 is driven by the first limiting member 2310 or the second limiting member 2410, so that the nut 33 rotates in a clockwise or counterclockwise direction, thereby realizing the locking or unlocking of the nut 33. The ratchet structure ensures that the nut 33 has a good anti-theft function.

[0136] Understandably, when the first limiting member 2310 engages with the ratchet 210, the locking assembly 220 is rotated to abut against the second limiting member 2410. At this time, the housing 1' can only drive the nut 33 to rotate in a clockwise direction. When the housing 1' rotates in a counterclockwise direction, the housing 1' rotates freely relative to the nut 33. The opposite is true when the second limiting member 2410 engages with the ratchet 210. With this design, when the housing 1' can drive the nut 33 in a clockwise direction, the internal thread of the nut 33 rotates relative to the external thread of the external structure to lock the nut 33. When the housing 1' drives the nut 33 in a counterclockwise direction, the nut 33 is separated and disassembled from the external structure.

[0137] It should be noted that the locking assembly 220 drives the first limiting member 2310 or the second limiting member 2410 to elastically resist the ratchet 210, which is achieved by the elastic deformation of the first elastic member 2320 or the second elastic member 2420. When the locking assembly 220 rotates to abut against the first limiting member 2310, the first limiting member 2310 will apply a pushing force to the first elastic member 2320 to press it down. At this time, one end of the second limiting member 2410 is not held by the locking assembly 220, and the second elastic member 2420 recovers its elastic deformation to elastically abut against the second limiting member 2410, so that the second limiting member 2410 engages with the ratchet 210. When the locking assembly 220 rotates to abut against the second limiting member 2410, the second limiting member 2410 will apply a pushing force to the second elastic member 2420 to press it down. At this time, one end of the first limiting member 2310 is not held by the locking assembly 220, and the first elastic member 2320 recovers its elastic deformation to elastically abut against the first limiting member 2310, so that the first limiting member 2310 engages with the ratchet 210.

[0138] Please refer to Figures 15 and 16. The first limiting member 2310 includes a first rotating shaft 23110 and a first supporting member 23120 connected together. The first supporting member 23120 can rotate relative to the first rotating shaft 23110. The side of the first supporting member 23120 away from the locking assembly 220 contacts the first elastic member 2320.

[0139] In the locking module 10' provided in this embodiment of the invention, the engagement between the abutment and the ratchet 210 is achieved through the cooperation between the abutment, the elastic member and the rotating shaft. The first rotating shaft 23110 is rotatable. During the process of rotating the locking assembly 220 to abut the first limiting member 2310, the first abutment 23120 rotates around the first rotating shaft 23110 as the rotation axis.

[0140] Similarly, the second limiting member 2410 includes a connected second rotating shaft 24110 and a second abutting member 24120. The second abutting member 24120 is rotatable relative to the second rotating shaft 24110. The side of the second abutting member 24120 away from the locking assembly 220 contacts the second elastic member 2420. The second rotating shaft 24110 itself is rotatable. During the process of rotating the locking assembly 220 to abut the second limiting member 2410, the second abutting member 24120 rotates about the second rotating shaft 24110 as the axis of rotation.

[0141] In some embodiments, the end of the first limiting member 2310 near the first rotating shaft 23110 serves as a rotating segment, which can drive the first supporting member 23120 to rotate relative to the first rotating shaft 23110, while the end near the first supporting member 23120 serves as a working segment, and the first elastic member 2320 is located on the side away from the locking assembly 220; the end of the second limiting member 2410 near the second rotating shaft 24110 serves as a rotating segment, which can drive the second supporting member 24120 to rotate relative to the second rotating shaft 24110, while the end near the second supporting member 24120 serves as a working segment, and the second elastic member 2420 is located on the side away from the locking assembly 220.

[0142] It should be noted that by setting a relatively rotatable shaft and abutment, as well as the cooperation relationship between the shaft, abutment and elastic element, it can be ensured that the ratchet 210 can only rotate in a specific direction in different locking modes, that is, drive the nut 33 to rotate to achieve one of the actions of locking or unlocking. This ensures that after the nut 33 is locked by rotating in one direction, it cannot be easily unlocked by rotating in another direction, thus improving the user experience of the locking module 10'.

[0143] Please refer to Figures 15 and 17. The first abutment member 23120 is provided with a first abutment surface 23130 and a second abutment surface 23140. The first abutment surface 23130 is located on the side of the first abutment member 23120 away from the first rotating shaft 23110, and the second abutment surface 23140 is located on the side of the first abutment member 23120 away from the first elastic member 2320. The second abutment member 24120 is provided with a third abutment surface 24130 and a fourth abutment surface 24140. The third abutment surface 24130 is located on the side of the second abutment member 24120 away from the second rotating shaft 24110, and the fourth abutment surface 24140 is located on the side of the second abutment member 24120 away from the second elastic member 2420.

[0144] In the locking module 10' provided in this embodiment of the invention, when the housing 1' rotates in a specific direction, since the rotating shaft is fixedly installed inside the housing 1', the abutting surface of the abutting member away from the rotating shaft can abut against the ratchet 210, thereby driving the nut 33 to rotate.

[0145] Understandably, the side of the first abutting member 23120 away from the first rotating shaft 23110 is the first abutting surface 23130, and the side of the first abutting member 23120 away from the first elastic member 2320 is the second abutting surface 23140. When the locking assembly 220 drives the first abutting member 23120 to elastically abut against the ratchet 210, the housing 1' is rotated clockwise. The first rotating shaft 23110 can drive the first abutting member 23120 to rotate the ratchet 210, thereby driving the nut 33 to rotate and locking the nut 33.

[0146] The side of the second abutment 24120 away from the second rotating shaft 24110 is the third abutment surface 24130, and the side of the second abutment 24120 away from the second elastic member 2420 is the fourth abutment surface 24140. When the locking assembly 220 drives the second abutment 24120 to elastically abut against the ratchet 210, the housing 1' is rotated counterclockwise. The second rotating shaft 24110 can drive the second abutment 24120 to rotate the ratchet 210, thereby driving the rotation of the nut 33 and realizing the disassembly of the nut 33.

[0147] It should be noted that since the first elastic element 2320 and the second elastic element 2420 are movable and deformable, the second abutment surface 23140 on the first abutment 23120 facing away from the first elastic element 2320 and the fourth abutment surface 24140 on the second abutment 24120 facing away from the second elastic element 2420 cannot drive the nut 33 to rotate. That is to say, when the first abutment 23120 abuts against the ratchet 210, rotating the housing 1 counterclockwise will cause the housing 1' to spin freely relative to the nut 33; when the second abutment 24120 abuts against the ratchet 210, rotating the housing 1' clockwise will cause the housing 1' to spin freely relative to the nut 33. Thus, it can be seen that the ratchet structure can realize the switching between the two working modes of the nut 33: disassembly mode and anti-theft mode.

[0148] Please refer to Figures 15 and 16. The locking assembly 220 can rotate relative to the housing 1' to hold the first abutment 23120 or the second abutment 24120, and respectively engage the second abutment 24120 or the first abutment 23120 with the ratchet 210.

[0149] In the locking module 10' provided in this embodiment of the invention, the locking component 220 can be rotated to control the engagement of the abutment and the ratchet 210. At this time, the ratchet 210 is in contact with the abutment surface on the abutment. When the nut 33 can rotate in a specific direction, the rotating shaft pushes the abutment surface on the abutment away from the rotating shaft to contact the ratchet 210, thereby driving the ratchet 210 to rotate. The two abutment components can realize that the nut 33 can rotate in opposite directions respectively.

[0150] Furthermore, when the first abutment member 23120 engages with the ratchet 210, the ratchet 210 contacts the first abutment surface 23130 and the second abutment surface 23140 respectively; when the second abutment member 24120 engages with the ratchet 210, the ratchet 210 contacts the third abutment surface 24130 and the fourth abutment surface 24140 respectively.

[0151] Understandably, the first abutment surface 23130 and the second abutment surface 23140 on the first abutment member 23120 are adjacent to each other, and the third abutment surface 24130 and the fourth abutment surface 24140 on the second abutment member 24120 are adjacent to each other.

[0152] When the first abutment member 23120 engages with the ratchet 210, rotating the housing 1' clockwise can cause the first abutment surface 23130 of the first abutment member 23120 to drive the ratchet 210 to rotate. When rotating the housing 1' counterclockwise, the first elastic member 2320 will cause the first abutment member 23120 to reciprocate in a circumferential direction relative to the ratchet 210, that is, it cannot drive the ratchet 210 to rotate. At this time, the housing 1' will spin freely relative to the ratchet 210. When the second abutment member 24120 engages with the ratchet 210, rotating the housing 1' counterclockwise can cause the third abutment surface 24130 of the second abutment member 24120 to drive the ratchet 210 to rotate. When rotating the housing 1' clockwise, the second elastic member 2420 will cause the second abutment member 24120 to reciprocate in a circumferential direction relative to the ratchet 210, that is, it cannot drive the ratchet 210 to rotate. At this time, the housing 1' will spin freely relative to the ratchet 210.

[0153] Please refer to Figures 15, 16 and 19. The locking assembly 220 includes a first rotating member 2210 and a second rotating member 2220 connected together. The first rotating member 2210 can drive the second rotating member 2220 to rotate relative to the housing 1', so that the second rotating member 2220 abuts against the first abutting member 23120 or the second abutting member 24120.

[0154] The housing 1' is provided with a first limiting hole 12', and the side of the first rotating member 2210 is provided with a boss 2230. The first rotating member 2210 and the boss 2230 are exposed after passing through the first limiting hole 12'. The boss 2230 can slide in the first limiting hole 12' to abut against the inner sidewall of the first limiting hole 12'.

[0155] In the locking module 10' provided in this embodiment of the invention, when the locking component 220 rotates, the first rotating component 2210 drives the second rotating component 2220 to rotate, thereby realizing the linkage between the second rotating component 2220 and the first rotating component 2210. The second rotating component 2220 abuts against the abutment on one side, so that the abutment on the other side engages with the ratchet 210.

[0156] Specifically, the rotation angle of the first rotating member 2210 can be adjusted by the portion of the first rotating member 2210 exposed in the first limiting hole 12', so as to drive the second rotating member 2220 to elastically abut against the first abutment member 23120 or the second abutment member 24120. When the first rotating member 2210 and the first elastic member 2320 abut against the first abutment member 23120, the second abutment member 24120 engages with the ratchet 210; when the second rotating member 2220 and the second elastic member 2420 elastically abut against the first abutment member 23120, the first abutment member 23120 engages with the ratchet 210.

[0157] Understandably, by providing a boss 2230 on the side of the first rotating member 2210 and providing a first limiting hole 12' on the housing 1' to expose the boss 2230, the boss 2230 slides within the first limiting hole 12' to abut against the inner sidewall of the first limiting hole 12', thereby achieving a limiting fit between the locking assembly 220 and the housing 1'. Furthermore, by opening the first limiting hole 12' to expose the first rotating member 2210 and the boss 2230 after they pass through, the user can know the current locking mode of the locking module 10', improving the user experience of the locking module 10'.

[0158] Furthermore, the first rotating member 2210 is provided at one end after passing through the first limiting hole 12', and the inner surface of the first rotating member 2210 cooperates with the external locking device.

[0159] In the locking module 10' provided in this embodiment of the invention, the inner surface of the first rotating member 2210 needs to cooperate with a specific external locking device. The first rotating member 2210 is driven by the external locking device to change the working mode of the nut 33. Through this design, it is possible to prevent outsiders from driving the supporting member to rotate using tools they have collected nearby, thereby achieving a good anti-theft effect.

[0160] Understandably, the first rotating member 2210 is provided at the end of the first rotating member 2210 as a polygonal groove, which requires a specific tool that is adapted to the shape of the first rotating member 2210 to cooperate with the first rotating member 2210 to control the rotation of the first rotating member 2210 and thus switch the working mode of the locking module 10'.

[0161] As an optional implementation, the first rotating member 2210 is a hexagonal groove, and the external locking device is an internal hex wrench. The internal hex wrench is inserted into the inner surface of the first rotating member 2210 to rotate the first rotating member 2210. That is to say, the locking module 10' in this embodiment of the invention requires an internal hex wrench of the corresponding size to operate the first rotating member 2210, so that the first rotating member 2210 rotates by a corresponding angle, so that the locking module 10' is in disassembly mode or anti-theft mode.

[0162] It is understood that the type and size of the first rotating member 2210 and the external locking device can be adjusted according to actual needs. The above description is only one embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included within the protection scope of the present invention.

[0163] The above design prevents outsiders from driving the first rotating component 2210 to switch the disassembly mode or anti-theft mode of the locking module 10' without using lock-picking tools or with only readily available tools, thus ensuring a good anti-theft effect.

[0164] Please refer to Figures 16 and 18. The housing 1' includes a cover 17 and a base plate 18. The inner wall of the cover 17 is provided with a first groove 171 and a second groove 172. The base plate 18 is provided with a first through hole 181 corresponding to the position of the first groove 171 and a second through hole 182 corresponding to the position of the second groove 172.

[0165] The top of the first rotating shaft 23110 abuts against the first groove 171, and the bottom passes through the first through hole 181; the top of the second rotating shaft 24110 abuts against the second groove 172, and the bottom passes through the second through hole 182.

[0166] In the locking module 10' provided in this embodiment of the invention, the groove provided on the inner wall of the cover 17 and the through hole provided on the bottom plate 18 can ensure the limiting of the first rotating shaft 23110 and the second rotating shaft 24110 when the housing 1' rotates. This ensures that the first abutment 23120 rotates only relative to the first rotating shaft 23110 and the second abutment 24120 rotates only relative to the second rotating shaft 24110, without shifting in other directions. This design can protect the limiting components and extend the service life of the locking module 10'.

[0167] Understandably, the first abutment 23120 is located on the circumferential outer surface of the first rotating shaft 23110. The top of the first rotating shaft 23110 is fixed by the first groove 171, and the bottom is fixed after passing through the first through hole 181. This allows the first rotating shaft 23110 to rotate only on its own, thereby driving the first abutment 23120 to rotate, without any offset in the horizontal or vertical direction of the housing 1'. The second abutment 24120 is located on the circumferential outer surface of the second rotating shaft 24110. The top of the second rotating shaft 24110 is fixed by the second groove 172, and the bottom is fixed after passing through the first through hole 181. This allows the second rotating shaft 24110 to rotate only on its own, thereby driving the second abutment 24120 to rotate, without any offset in the horizontal or vertical direction of the housing 1', thus improving the stability of the limiting assembly during use.

[0168] Please refer to Figures 15 and 18. The circumferential outer surface of the nut 33 abuts against the inner wall of the cover 17 on the hollow channel 16, and the top surface of the ratchet 210 abuts against the inner wall surface of the cover 17 away from the base plate 18 to close the receiving cavity 11'.

[0169] In the locking module 10' provided in this embodiment of the invention, by restricting the movement of the ratchet 210 and the nut 33 in their vertical and horizontal directions, the overall structural stability of the ratchet 210 and the nut 33 can be ensured, and the stability of the ratchet 210 and the nut 33 fixedly connected to the housing 1' can be ensured, so that the limiting member can smoothly engage with the ratchet 210, and drive the ratchet 210 and the nut 33 to rotate together when the cover 17 rotates in a specific direction.

[0170] Understandably, the ratchet structure is set in the receiving cavity 11', and the closure of the receiving cavity 11' is achieved by the ratchet 210 abutting against the inner wall of the cover 17, the nut 33 being fixedly placed on the base plate 18, and the nut 33 abutting against the inner side wall of the cover 17.

[0171] Specifically, when the cover 17 is closed on the base plate 18, the nut 33 is fixedly placed on the base plate 18. The inner wall of the cover 17 and the inner bottom wall of the base plate 18 abut against the upper and lower ends of the ratchet 210, which can prevent the nut 33 from moving in the vertical direction. The outer circumferential surface of the nut 33 can abut against the inner side wall of the cover 17. Since the ratchet 210 is located on the outer circumferential surface of the nut 33, that is, the nut 33 is located on the inner ring of the ratchet 210, the abutment against the inner side wall of the cover 17 can prevent the nut 33 from moving in the horizontal direction, ensuring that the locking module 10' can be used normally and has an anti-theft effect.

[0172] Further, referring to Figures 1-4, this embodiment of the invention also provides a clamping device 100, including a fixed clamp 20, a movable clamp 30, and the aforementioned locking module 10; the fixed clamp 20 and the movable clamp 30 are rotatably connected, and the locking module 10 is movably connected to the movable clamp 30 after passing through the fixed clamp 20 on one side; the locking module 10 includes a housing 1, a transmission structure 2, and a fastener 3, the housing 1 has a receiving cavity 11 inside, the transmission structure 2 includes a gear shaft 21 disposed in the receiving cavity 11, one end of the fastener 3 is connected to the gear shaft 21, and the other end extends outward from the receiving cavity 11 and is connected to the movable clamp 30.

[0173] It should be noted that the fastener 3 is connected to the gear shaft 21. That is, when the gear shaft 21 rotates, it will drive the fastener 3 to rotate, thereby locking or disengaging the fastener 3 from the movable chuck 30.

[0174] As a clamp for assisting in fixing electronic devices, the clamping device 100 includes a fixed clamp 20 and a movable clamp 30 that are rotatably connected. The fixed clamp 20 and the movable clamp 30 cooperate to clamp the clamping device 100 on a vehicle, the edge of a desktop, the top of a television set, etc., and the relative position of the clamp 20 and the movable clamp 30 is fixed by the locking module 10, thereby fixing the clamping device 100 to the relevant equipment.

[0175] The clamping device 100 provided in this embodiment solves the problem of poor anti-theft effect of existing clamping devices 100 by connecting the fixed clamp 20 and the movable clamp 30 with a locking module 10 having anti-theft function.

[0176] Furthermore, the movable chuck 30 includes a movable clamping section 301 and a movable connecting section 302 connected together. The movable connecting section 302 is rotatably connected to the fixed chuck 20. The movable connecting section 302 is provided with a limiting groove 303. A limiting member 304 is provided in the limiting groove 303. The end of the fastener 3 away from the housing 1 is fixedly connected to the limiting member 304.

[0177] As a feasible implementation, the fastener 3 extends from the end away from the housing 1 through the fixed clamp 20 and extends towards the movable connecting section 302 and connects with the limiting member 304. By rotating the housing 1, the fastener 3 is driven to rotate, thereby causing the movable clamp 30 to rotate relative to the fixed clamp 20, so as to adjust the clamping size between the fixed clamp 20 and the movable clamp 30.

[0178] Understandably, the movable connecting section 302 is rotatably connected to the fixed chuck 20, thereby allowing the clamping size between the movable chuck 30 and the fixed chuck 20 to be adjusted so that the clamping device 100 can clamp devices of different sizes. One end of the housing 1 of the transmission structure 2 is located at the end of the fixed chuck 20 away from the movable chuck 30. The fastener 3 passes through the fixed chuck 20 and connects to the movable chuck 30. The housing 1 drives the fastener 3 to rotate, thereby causing the movable chuck 30 to rotate relative to the fixed chuck 20 so that the clamping device 100 can clamp external devices.

[0179] Furthermore, the fixed clamp 20 is provided with a strip-shaped clearance hole 201 along its length, and the fastener 3 is movably engaged with the clearance hole 201.

[0180] Understandably, when the movable chuck 30 rotates relative to the fixed chuck 20, the corresponding position of the connection point between the movable chuck 30 and the fastener 3 relative to the fixed chuck 20 will also change, thereby causing the fastener 3 on it to be displaced. Through the design of the clearance hole 201, the fastener 3 has room to move when the movable chuck 30 rotates, so as to avoid the rotation of the movable chuck 30 being affected by the restricted movement of the fastener 3.

[0181] Specifically, the fixed chuck 20 and the movable chuck 30 are connected by a clearance groove 202, and the end of the clearance groove 202 away from the movable chuck 30 is provided with a snap-fit ​​groove 203;

[0182] The fixed clamp 20 includes a rotating rod 204 and an elastic element 205. The rotating rod 204 is disposed in the relief groove 202, and the elastic element 205 is sleeved on the rotating rod 204 and located in the snap-fit ​​groove 203. One end of the movable clamp 30 extends into the relief groove 202 and is rotatably connected to the rotating rod 204.

[0183] Optionally, the elastic element 205 is a torsion spring.

[0184] In the clamping device 100 provided in this embodiment, the rotating rod 204 connects the movable clamp 30 and the fixed clamp 20, so that the movable clamp 30 and the fixed clamp 20 can be rotatably connected. The elastic element 205 sleeved on the rotating rod 204 can provide directional tension to the movable clamp 30, so that the fixed clamp 20 and the movable clamp 30 can maintain the current clamping state.

[0185] Understandably, the movable chuck 30 and the fixed chuck 20 are rotatably connected by the rotating rod 204, so that the movable chuck 30 can rotate relative to the fixed chuck 20 to adjust the size of the clamping opening between the movable chuck 30 and the fixed chuck 20, thereby enabling the clamping device 100 to be clamped onto equipment of different sizes and improving the applicability of the clamping device 100.

[0186] Please refer to Figure 13. As another feasible implementation, the clamping device 100' includes a clamping module 60, a support module 70, and the aforementioned locking module 10' connected in sequence. The clamping module 60 is provided with a first connector 601, and the support module 70 is provided with a second connector 701 connected to the first connector 601. The locking module 10' includes a housing 1', a nut 33, and a transmission structure 2'. The housing 1' is provided with a hollow channel 16 for fixing and placing the nut 33. The housing 1' and the transmission structure 2' cooperate to drive the nut 33 to rotate, thereby locking the first connector 601 and the second connector 701.

[0187] As a clamp for assisting in fixing electronic devices, the clamping device 100' includes a clamping module 60, a bracket module 70, and a locking module 10' connected in sequence. The clamping module 60 can be fixed on a vehicle or clamped on the edge of a table, the top of a television, or other positions. The bracket module 70 is mainly used to connect with different external bracket components to fix electronic devices such as microphones, cameras, mobile phones, or tablets. The locking module 10' is used to lock the clamping module 60 after it is connected to the bracket module 70.

[0188] Specifically, in this embodiment of the invention, the first connector 601 on the clamping module 60 can be detachably connected to the second connector 701 on the bracket module 70, and the nut 33 rotates to lock the first connector 601 and the second connector 701 together.

[0189] In one embodiment, the first connector 601 is a ball head bracket, and the second connector 701 is a threaded bracket; the outer circumferential surface of the second connector 701 is provided with a second external thread 7010, and the inner circumferential surface of the nut 33 is provided with a second internal thread 331. The nut 33 can rotate relative to the second connector 701 to lock the first connector 601.

[0190] In the clamping device 100' provided in this embodiment of the invention, the first connector 601 and the second connector 701 are a ball head bracket and a threaded bracket, respectively, and the ball head bracket can be engaged with the threaded bracket.

[0191] It should be noted that, since the outer circumferential surface of the second connector 701 is provided with a second external thread 7010 and the inner circumferential surface of the nut 33 is provided with a second internal thread 331, that is, the nut 33 and the second connector 701 are threadedly connected. When the ratchet structure rotates, the nut 33 can lock or disassemble the second connector 701, thereby locking and fixing the first connector 601, making it impossible for the first connector 601 to separate from the second connector 701, extending the service life of the clamping device 100' and improving the user experience.

[0192] Please refer to Figure 20. This embodiment of the invention also provides an electronic device bracket 200 for placing electronic devices. The electronic device bracket 200 includes the clamping device 100 or clamping module 100' described above.

[0193] It is understood that the electronic device bracket 200 of this embodiment has the same beneficial effects as the clamping device 100 or clamping module 100' of the above embodiments. The electronic devices include, but are not limited to, microphones, cameras, mobile phones and tablet computers.

[0194] In some embodiments, the electronic device bracket 200 generally includes a bracket body 2001, which is detachably or fixedly connected to the clamping device 100 or the clamping module 100', and the electronic device is fixed by the bracket body 2001.

[0195] It should be noted that users can use the electronic device holder 200 on vehicles such as cars, bicycles, electric bicycles, and motorcycles, thus eliminating the need to constantly hold electronic devices, freeing up their hands, and greatly improving safety during travel, thereby reducing the probability of traffic accidents on the road.

[0196] Further, please refer to Figures 21 and 22. An embodiment of the present invention provides a device 300 with anti-theft function. The device 300 includes the locking module 10 or locking module 10' described above.

[0198] It should be noted that anti-theft nuts have been widely used in many fields, such as infrastructure fields like national power transmission towers and signal towers, as well as industrial manufacturing fields like engineering machinery, construction equipment, and auto parts. With continuous technological breakthroughs in this field, anti-theft nuts will be applied to a series of fields with extremely high requirements for fastener safety, such as aerospace, heavy machinery, and high-speed railways.

[0199] In some embodiments, the device 300 further includes a first connecting component 40 and a second connecting component 50, the first connecting component 40 and the second connecting component 50 being detachably connected via a locking module 10 or a locking module 10'.

[0200] It should be noted that in this embodiment, the device 300 can be a power tower, transformer or other power equipment. Theft or damage to the fasteners of power equipment may lead to serious safety accidents. The device 300 can also be a public facility such as a street light or traffic sign. Fasteners on public facilities are also easy to be stolen. By using the locking module 10 or locking module 10', the service life of public facilities can be extended, thereby reducing maintenance costs.

[0201] Specifically, the device 300 can also be a vehicle such as a car or motorcycle, which can use the locking module 10 or locking module 10' to fix the engine, wheel hubs and license plate and other parts of the vehicle to prevent theft or illegal modification; the device 300 can also be a display case and collection cabinet for valuables to protect valuables such as works of art, jewelry and gold from theft and property loss.

[0202] In addition, equipment 300 can also be some key equipment in industrial and agricultural production, such as industrial equipment such as engines and transmission devices, as well as agricultural equipment such as tractors and harvesters, to prevent outsiders from illegally dismantling and stealing them, so as to ensure the normal operation and safety of industrial and agricultural equipment.

[0204] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
