Description

Technical Field

[0001] This utility model relates to the field of quick-release device technology, and in particular to a rotary pitch gasket. Background Technology

[0002] To facilitate transportation and installation, modern bicycles generally use quick-release technology, which uses the rotation of the quick-release handle to tighten the wheel instead of the traditional screw tightening method. This technology is widely used for wheel fixing and seat height adjustment. However, existing quick-release handles basically change the eccentricity to achieve locking or unlocking. However, the positioning of the eccentric hole is not accurate, which increases the difficulty of processing. Furthermore, the eccentricity can cause problems such as difficulty in locking or easy loosening after locking, resulting in a poor user experience. Utility Model Content

[0003] The purpose of this utility model is to solve the problems in the prior art where the positioning of the eccentric hole of the quick-release handle is inaccurate, which increases the processing difficulty and makes locking difficult or easy to loosen after locking, resulting in a poor user experience. Therefore, a rotary pitch shim is proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rotary pitch shim includes a convex shim and a concave shim that mate with each other. The convex shim and the concave shim are fitted with a mating structure. The convex shim and the concave shim are rotated relative to each other to cause the mating structure to misalign and generate a pitch change between the convex shim and the concave shim. The convex shim and the concave shim are provided with auxiliary components to assist in generating a pitch change due to rotation.

[0006] Preferably, the mating structure includes a main protrusion and a main concave block respectively mounted on the convex washer and the concave washer, wherein the main protrusion and the main concave block move against each other.

[0007] Preferably, the convex washer has a first mounting hole for mounting the rotating shaft, and the concave washer has a second mounting hole for mounting the rotating shaft.

[0008] Preferably, the auxiliary component includes a secondary concave block installed on the convex washer away from the main convex block, and the secondary concave block is installed on the concave washer away from the main concave block, and the secondary concave block and the secondary convex block move against each other.

[0009] Preferably, when the convex washer and the concave washer rotate relative to each other, the main convex block moves to abut against the secondary convex block to increase the pitch of the convex washer and the concave washer.

[0010] Preferably, a first mounting block is installed on one side of the convex gasket, and the first mounting block has a cylindrical structure.

[0011] Preferably, a second mounting block is installed on one side of the concave gasket, and the second mounting block has a rectangular structure.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention achieves tight contact between the convex and concave pads by having the main convex block abut against the main concave block and the secondary concave block abut against the secondary convex block, thereby increasing the friction between them and clamping the two quick-release handles. By having the main convex block abut against the secondary convex block and the main concave block align with the secondary concave block, the distance between the convex and concave pads is increased, enabling the quick release of the two quick-release handles. This eliminates the need to machine eccentric holes, reducing machining difficulty. Furthermore, the change in distance generated by the rotation of the convex and concave pads allows for quick clamping or release, improving the problems of clamping difficulties and loose clamping caused by eccentricity.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-3 A rotary pitch-changing shim includes a convex shim 1 and a concave shim 2 that mate with each other. The convex shim 1 and the concave shim 2 are respectively equipped with mating structures. The convex shim 1 and the concave shim 2 are rotated relative to each other to cause the mating structures to misalign and generate a pitch change between the convex shim 1 and the concave shim 2. The convex shim 1 and the concave shim 2 are provided with auxiliary components to assist in the pitch change generated by rotation. The mating structure includes a main protrusion 3 and a main concave block 4 respectively installed on the convex shim 1 and the concave shim 2, and the main protrusion 3 and the main concave block 4 are movably abutted against each other.

[0020] Preferably, the convex washer 1 has a first mounting hole 5 for mounting the rotating shaft, and the concave washer 2 has a second mounting hole 6 for mounting the rotating shaft. A first mounting block 9 is mounted on one side of the convex washer 1. The first mounting block 9 has a cylindrical structure. The matching quick-release handle has a mounting plate with a circular groove for placing the first mounting block 9 to improve the stability of the convex washer 1 after installation. The mounting plate is rotatably connected to the rotating shaft of the quick-release handle. A second mounting block 10 is mounted on one side of the concave washer 2. The second mounting block 10 has a rectangular structure. The matching quick-release handle has a mounting plate with a square groove for placing the second mounting block 10 to improve the stability of the concave washer 2 after installation. The mounting plate is rotatably connected to the rotating shaft of the quick-release handle.

[0021] Preferably, the auxiliary components include a secondary concave block 7 installed on the convex washer 1 away from the main protrusion 3, and a secondary protrusion 8 installed on the concave washer 2 away from the main concave block 4. The secondary concave block 7 and the secondary protrusion 8 move against each other. When it is necessary to separate the convex washer 1 and the concave washer 2, the convex washer 1 and the concave washer 2 are driven to rotate relative to each other, so that the main protrusion 3 moves to the point where the secondary protrusion 8 abuts, thereby increasing the pitch of the convex washer 1 and the concave washer 2, and thus separating the convex washer 1 and the concave washer 2; when it is necessary to clamp the convex washer 1 and the concave washer 2, the convex washer 1 and the concave washer 2 are driven to rotate relative to each other, so that the main protrusion 3 and the main concave block 4 abut against each other, thereby increasing the friction between the convex washer 1 and the concave washer 2, and thus clamping the convex washer 1 and the concave washer 2.

[0022] The functional principle of this utility model can be explained through the following operation methods:

[0023] First, install the convex washer 1 and the concave washer 2 onto the pivot of the two quick-release handles through the first mounting hole 5 and the second mounting hole 6 respectively. Then, drive the convex washer 1 and the concave washer 2 to rotate relative to each other through the two quick-release handles, so that the main convex block 3 abuts against the main concave block 4, and the secondary concave block 7 abuts against the secondary convex block 8, so that the convex washer 1 and the concave washer 2 fit tightly together and increase the friction between them, thereby achieving the clamping of the two quick-release handles.

[0024] When it is necessary to separate the two quick-release handles, the convex washer 1 and concave washer 2 are rotated relative to each other, so that the main convex block 3 abuts against the secondary convex block 8, and the main concave block 4 aligns with the secondary concave block 7, thereby increasing the distance between the convex washer 1 and concave washer 2 to achieve quick separation of the two quick-release handles.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
