Description

Technical Field

[0001] This utility model relates to the field of locking and releasing structure technology, and in particular to a clamping mechanism. Background Technology

[0002] In mechanical structures, telescopic sleeve structures are commonly used in the mechanical field. They typically employ a combination of a screw and a nut sleeve to achieve telescopic movement.

[0003] However, although the combination of screw and nut sleeve can achieve stable and controllable telescopic adjustment, the adjustment speed is slow. Especially when the user adjusts manually or needs to remove the screw, the screw or nut sleeve needs to be rotated, which is time-consuming and laborious, resulting in a poor user experience.

[0004] Therefore, a clamping mechanism is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping mechanism that can selectively clamp or release moving parts by driving two clamping members to rotate, which is highly efficient in adjustment and disassembly, saves manpower, and improves user experience.

Two clamping members are symmetrically arranged and form a clamping cavity between them to accommodate at least a portion of the movable member. The first end of the clamping member is provided with a pressing part, and the second end of the clamping member is provided with an operating part. The operating part is used to drive the clamping member to rotate on the mounting member. When the two pressing parts move towards each other, the clamping cavity clamps the movable member; when the two pressing parts move away from each other, the clamping cavity releases the movable member.

[0010] Preferably, the clamping part includes: a clamping frame that extends outward from the first end surface of the clamping member, and the clamping frame and the clamping member form the clamping cavity.

[0011] Preferably, the clamping part further includes a clamping block, wherein the clamping frame is provided with a mounting hole, the clamping block is correspondingly disposed in the mounting hole, and the clamping block is used to abut against the movable part.

[0012] Preferably, the inner wall of the mounting hole is provided with a deformation notch.

[0013] Preferably, the clamping frame has a guide ramp on the surface near the clamping cavity, the guide ramp being used to guide the clamping block into the clamping cavity.

[0014] Preferably, a clamping block is provided on the inner wall of the clamping cavity, and the clamping block abuts against the pressing block.

[0015] Preferably, the clamping block is provided with a receiving groove, and the receiving groove is provided with locking patterns.

[0016] Preferably, the clamping block is provided with a locking groove, and when the clamping block is installed in the mounting hole, the clamping frame secures the locking groove.

[0017] Preferably, the clamping member has a rotating part in the middle, and the rotating part is rotatably connected to the mounting member.

[0018] Preferably, the device further includes: an elastic reset member, which is connected to the mounting member and / or the clamping member, wherein when the clamping part moves toward the mounting member, the elastic reset member deforms and drives the clamping part to move away from the mounting member.

[0019] The beneficial effects of this utility model are:

[0020] The clamping mechanism provided by this utility model has clamping members rotatably mounted on the mounting component. A clamping cavity, capable of accommodating at least a portion of the movable component, is provided between the two clamping members.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] like Figures 1-4 As shown, this embodiment provides a clamping mechanism for selectively clamping a movable component 100 to lock its position. The movable component 100 can specifically be a screw, bolt, pin, connecting rod, or other structural component; in this embodiment, a screw is used as the movable component 100 for explanation. The clamping mechanism includes a mounting component 10 and two clamping components 20. The mounting component 10 has a mounting cavity 101, and the two clamping components 20 are symmetrically and rotatably mounted in the mounting cavity 101. Each clamping component 20 has a pressing portion 21 at its first end and an operating portion 22 at its second end.

[0035] Furthermore, such as Figure 1 and Figure 2 As shown, a clamping cavity 201 is provided between the two clamping members 20 to accommodate at least part of the movable member 100. The operating part 22 is used to drive the clamping members 20 to rotate on the mounting member 10. When the two pressing parts 21 move towards each other, the clamping cavity 201 clamps the movable member 100; when the two pressing parts 21 move away from each other, the clamping cavity 201 releases the movable member 100.

[0036] Specifically, the clamping mechanism provided in this embodiment can selectively clamp or release the movable part 100. When the user rotates the two clamping parts 20 by using the two operating parts 22 respectively, the two pressing parts 21 move closer together, and the clamping cavity 201 between the two clamping parts 20 clamps the movable part 100; when the user rotates the two clamping parts 20 in opposite directions by using the two operating parts 22 respectively, the two pressing parts 21 move away from each other, and the clamping cavity 201 between the two clamping parts 20 releases the movable part 100. In summary, the clamping mechanism provided in this embodiment can selectively clamp or release the movable part 100 by driving the two clamping parts 20 to rotate, without the need to adjust the position of the movable part 100 by turning, which is highly efficient for adjustment and disassembly, saves manpower, and improves the user experience.

[0037] For example, two sub-cavities are symmetrically arranged in the mounting cavity 101, and two mounting parts 10 are respectively disposed in the two sub-cavities.

[0038] For example, such as Figure 4As shown, the clamping part 21 includes a clamping frame 211, which extends outward from the first end surface of the clamping member 20, forming a clamping cavity 201 between the clamping frame 211 and the side wall of the clamping member 20. Further, the clamping part 21 also includes a clamping block 30. The clamping frame 211 has a mounting hole 212, and the clamping block 30 is correspondingly disposed in the mounting hole 212, serving to abut against the movable member 100. When the first ends of the clamping members 20 come together, the two clamping blocks 30 press against the peripheral wall of the movable member 100 from both sides.

[0039] For example, such as Figure 4 As shown, the clamping block 30 is provided with a clamping groove 33. When the clamping block 30 is installed in the mounting hole 212, the clamping frame 211 tightens the clamping groove 33 so that the clamping block 30 and the clamping frame 211 are fixed to each other and the clamping block 30 is prevented from falling off.

[0040] For example, such as Figure 4 As shown, the inner side of the clamping block 30 is provided with a receiving groove 31. The inner wall of the receiving groove 31 is set as a concave arc surface structure, which can be matched with the movable parts 100 of various sizes. The receiving groove 31 is provided with locking grooves 32 that are adapted to the peripheral wall of the movable part 100. The locking grooves 32 can be set as an internal thread structure or as multiple groove structures distributed along the axial direction.

[0041] For example, such as Figure 4 As shown, the inner wall of the mounting hole 212 is provided with a deformation notch 213. The deformation notch 213 is located at the four corners of the mounting hole 212. When the two clamping parts 21 come close to each other, the two clamping frames 211 on the opposite side come into contact and undergo elastic deformation. The setting of the deformation notch 213 increases the deformation range of the clamping frame 211, and the clamping force can be more fully transmitted to the clamping block 30 to improve the clamping force.

[0042] For example, such as Figure 4 As shown, a clamping block 215 is provided on the inner wall of the clamping cavity 201. The clamping block 215 is located on the side wall of the clamping frame 211 away from the movable part 100. The clamping block 215 presses against the pressing block 30, and the body of the clamping part 20 applies force to the pressing block 30 through the clamping block 215.

[0043] For example, the stiffness of the clamping block 30 is greater than that of the clamping frame 211. The clamping block 30 may be made of metal or rubber, plastic or other materials with stiffness greater than that of the clamping frame 211.

[0044] For example, such as Figure 4As shown, a guide slope 214 is provided on the surface of the clamping frame 211 near the clamping cavity 201. The thickness of the guide slope 214 gradually increases towards the mounting hole 212. The guide slope 214 is used to guide the clamping block 30 into the clamping cavity 201, reducing the installation difficulty.

[0045] For example, such as Figure 3 and Figure 4 As shown, the clamping member 20 has a rotating part 24 in the middle, which is rotatably connected to the mounting member 10. In this embodiment, the rotating part 24 is a rotating rod structure, and rotating holes 102 are symmetrically opened on the inner wall of the mounting cavity 101. The two ends of the rotating part 24 are correspondingly inserted into the two rotating holes 102. In other embodiments, the rotating part 24 can also be set as a mounting hole, and a rotating column can be provided on the inner wall of the mounting cavity 101. The rotating column is inserted into the mounting hole, which can also make the clamping member 20 rotate relative to the mounting member 10.

[0046] For example, the clamping mechanism provided in this embodiment further includes: an elastic reset member 23, which is connected to the mounting member 10 and / or the clamping member 20. When the pressing part 21 moves toward the mounting member 10, the elastic reset member 23 deforms and drives the pressing part 21 to move away from the mounting member 10.

[0047] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, an elastic reset member 23 is provided between the clamping member 20 and the inner wall of the mounting member 10. When the pressing part 21 moves toward the inner wall of the mounting member 10, the elastic reset member 23 is deformed by the inner wall of the mounting member 10 and drives the pressing part 21 to move away from the inner wall of the mounting member 10. In its natural state, the elastic reset member 23 is in a compressed state and has a tendency to drive the clamping member 20 to rotate around the first direction, thereby clamping the movable member 100 in the clamping cavity 201. When the user moves the operating part 22, it can drive the two pressing parts 21 to move away from each other, and the clamping cavity 201 releases the movable member 100. At this time, the elastic reset member 23 is further compressed, and its elastic potential energy increases. After the user removes the force, the elastic reset member 23 drives the clamping member 20 to reset and re-clamp the movable member 100.

[0048] In this embodiment, as Figure 1 , Figure 2 and Figure 4As shown, the elastic reset member 23 is integrally formed on the first end of the clamping member 20. The elastic reset member 23 extends toward the inner wall of the mounting cavity 101, and the end of the elastic reset member 23 presses against the inner wall of the mounting cavity 101. When the clamping part 21 moves toward the inner wall of the mounting cavity 101, the elastic reset member 23 is deformed by the squeezing of the inner wall of the mounting cavity 101, and drives the clamping part 21 to move away from the inner wall of the mounting cavity 101. Specifically, the elastic reset member 23 is provided on the side opposite to the clamping part 21. The elastic reset member 23 is configured as a curved plate structure extending along an arc path. One end of the elastic reset member 23 is connected to the body of the clamping member 20, and the other end presses against the inner wall of the mounting cavity 101. In its natural state, the elastic reset member 23 is squeezed by the inner wall of the mounting cavity 101, thereby pushing the clamping part 21 inward, so that the two clamping parts 21 come closer to each other, thereby clamping the movable member 100 by the clamping cavity 201; when the user moves the operating part 22, the elastic reset member 23 moves toward the inner wall of the mounting cavity 101 and is squeezed and deformed.

[0049] For example, such as Figure 1 , Figure 2 and Figure 4 As shown, the end of the elastic reset member 23 is provided with a support body 231, which abuts against the inner wall of the mounting cavity 101. Specifically, the support body 231 is configured as a cylindrical structure, which abuts against the inner wall of the mounting cavity 101 through its arc-shaped peripheral wall. When the clamping member 20 moves relative to the mounting cavity 101, the support body 231 can slide smoothly on the inner wall of the mounting cavity 101, reducing sliding friction, making the locking and unlocking actions smoother, and extending the service life.

[0050] In other embodiments of this utility model, the elastic reset member 23 may also be formed on the inner wall of the mounting cavity 101, with one end connected to the inner wall of the mounting cavity 101 and the other end abutting against (or connected to) the clamping member 20. The elastic reset member 23 is in a compressed state and has a tendency to drive the clamping cavity 201 to clamp the movable member 100. In other embodiments, the elastic reset member 23 may also be an independently set structural member, such as a spring with one end connected to the inner wall of the mounting cavity 101 and the other end extending toward the clamping member 20, or a spring with one end connected to the clamping member 20 and the other end extending toward the inner wall of the mounting cavity 101, or a spring with both ends connected to the inner wall of the mounting cavity 101 and the clamping member 20 respectively, or a torsion spring sleeved on the rotating part 24, with both ends connected to the clamping member 20 and the inner wall of the mounting cavity 101 respectively, which also has a tendency to drive the clamping member 20 to rotate so that the clamping cavity 201 clamps the movable member 100.

[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
