Description

Technical Field

[0001] This utility model relates to the field of clamps, and in particular to handlebar clamps. Background Technology

[0002] In existing technologies, handlebar installation is crucial. The existing handlebars are mainly fixed by installing a cover plate on the main frame and tightening bolts. This connection method is relatively convenient, but the force applied by the clamp to the frame tubes is concentrated or unevenly distributed, resulting in excessive local stress on the tubes, causing dents or twisting. Therefore, a handlebar clamp is proposed. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] The handlebar chuck includes a rack, a ball joint connecting rod threaded to the rack, and a rotating component that threadedly fixes the rack to the ball joint connecting rod. A limiting platform is provided between the rack and the ball joint connecting rod, with one end of the rack located at the bottom of the limiting platform and the other end of the rack located above the limiting platform. The rack is bent to form a U-shaped groove for mounting a column, and an installation gap is formed between the limiting platform and the rack for the column to pass through. A through hole is formed above the limiting platform for the rack to pass through.

[0005] Preferably, the rack assembly is provided with a soft protective sleeve that fits against the surface of the column and prevents it from slipping during installation, and a rubber pad is provided on one side of the limiting platform that is opposite to the soft protective sleeve and prevents it from slipping during installation.

[0006] Preferably, a screw is provided between the limiting platform and the rubber pad, and the screw passes through the rubber pad and connects to the ball head connecting rod, and the rubber pad is located on the side of the limiting platform by the screw.

[0007] Preferably, the ball joint connecting rod is formed with a limiting rib that limits the movable end of the rack, and the limiting rib is located above the ball joint connecting rod, and the movable end of the rack passes through the limiting rib.

[0008] Preferably, a positioning post is vertically provided on one side of the bottom end of the ball joint connecting rod, and a spring is elastically provided at the bottom end of the positioning post, and a glass bead that makes elastic contact with the rotating part is elastically connected to the other end of the spring.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When the ball joint connecting rod needs to be fixed to the handlebar or other related columns, the movable end of the rack comes up from the lower end of the limiting platform, goes around the column and passes through the through hole above the limiting platform, and continuously pulls the rack so that one end of the limiting platform and the U-shaped groove formed by its internal bending fit into the outer curved surface of the column. At this time, the rotating part is screwed into one end of the ball joint connecting rod, so that the rotating part gradually rotates to the limiting platform and is threadedly connected with the rack, so that the ball joint connecting rod is first pre-fixed to the column. Then, the rack is pulled so that one end of the limiting platform and the U-shaped groove formed by its internal bending fit into the outer curved surface of the column. Then the rotating part is rotated so that the rotating part and the rack are threadedly connected, so that the ball joint connecting rod is fixed to the column through the cooperation between the rotating part, the rack and the limiting platform, which is convenient for assembly.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 In this embodiment of the invention, the handlebar clamp includes a rack 3, a ball joint connecting rod 1 threadedly connected to the rack 3, and a rotating component 2 threadedly fixing the rack 3 to the ball joint connecting rod 1. A limiting platform 9 is provided between the rack 3 and the ball joint connecting rod 1, with one end of the rack 3 located at the bottom of the limiting platform 9 and the other end located above the limiting platform 9. The rack 3 is bent to form a U-shaped groove (not shown in the figure) for mounting a column, and an installation gap is formed between the limiting platform 9 and the rack 3 for the column to pass through. A through hole (not shown in the figure) is formed above the limiting platform 9 for the rack 3 to pass through. Thus, when the ball joint connecting rod 1 needs to be fixed to the handlebar or other related columns, the movable end of the rack 3 moves from the lower end of the limiting platform 9. The rack 3 is pulled around the column and through the through hole above the limiting platform 9. The rack 3 is pulled continuously so that one end of the limiting platform 9 and the U-shaped groove formed by its internal bending fit into the outer curved surface of the column. Then, the rotating part 2 is screwed into one end of the ball head connecting rod 1 so that the rotating part 2 gradually rotates onto the limiting platform 9 and is threadedly connected to the rack 3. The ball head connecting rod 1 is pre-fixed to the column. Then, the rack 3 is pulled so that one end of the limiting platform 9 and the U-shaped groove formed by its internal bending fit into the outer curved surface of the column. The rotating part 2 is then rotated so that the rotating part 2 and the rack 3 are threadedly connected. The ball head connecting rod 1 is fixed to the column through the cooperation between the rotating part 2, the rack 3 and the limiting platform 9, which is convenient for assembly.

[0020] The rack 3 is fitted with a soft protective sleeve 4 that fits against the surface of the cylinder and prevents slippage during installation. A rubber pad 8 is also provided on one side of the limiting platform 9, opposite the soft protective sleeve 4 and preventing slippage during installation. Since both the soft protective sleeve 4 and the rubber pad 8 are arc-shaped, when the rack 3 and the rubber pad 8 clamp the handlebar or cylinder, they are completely in contact with the arc surface of the handlebar or cylinder. This allows the rack 3 and the limiting platform 9 to fit more closely to the arc of the handlebar or cylinder, thereby increasing the friction between the soft protective sleeve 4 and the rubber pad 8 and the handlebar or cylinder, respectively.

[0021] A screw 7 is provided between the limiting platform 9 and the rubber pad 8, and the screw 7 passes through the rubber pad 8 and connects with the ball head connecting rod 1. The screw 7 also makes the rubber pad 8 located on the side of the limiting platform 9.

[0022] The ball joint connecting rod 1 is formed with a limiting rib 11 that limits the movable end of the rack 3. The limiting rib 11 is located above the ball joint connecting rod 1, and the movable end of the rack 3 passes through the limiting rib 11, thereby limiting the movable end of the rack 3 through the limiting rib 11.

[0023] A positioning post 10 is vertically arranged on one side of the bottom end of the ball joint connecting rod 1, and a spring 5 is elastically arranged at the bottom end of the positioning post 10. The other end of the spring 5 is elastically connected to a glass bead 6 that makes elastic contact with the rotating part 2. When the rotating part 2 fixes the rack 3 together with the limiting platform 9 to the ball joint connecting rod 1, the glass bead 6 at the lower end of the positioning post 10 elastically abuts against the inner side wall of the connecting frame 2 due to the elastic nature of the spring 5. This makes a sound when the rotating part 2 and the rack 3 are threaded together, so that the user can clearly understand the installation status of the rotating part 2.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
