Description

Technical Field

[0001] This utility model belongs to the field of motorcycle technology, and more specifically, it is a rear shock absorber spring preload adjustment wrench. Background Technology

[0002] Shock absorbers are installed between the motorcycle frame and the wheels to provide overall shock absorption. The shock absorber springs are pre-adjusted to adjust their elasticity and pressure to meet the required shock absorption. The shock absorber springs are hidden inside the motorcycle body for protection and aesthetics. An adjustment port is provided on the body for a wrench to be inserted into the spring adjustment teeth for adjustment. However, current wrenches are designed as long, thin strips; the locking teeth on the head engage with the adjustment teeth, and the wrench is operated to rotate the teeth. Because of the lack of proper force support, this makes adjustment quite difficult for the user. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a rear shock absorber spring preload adjustment wrench. Through structural design, the wrench can be supported on the outer periphery of the adjustment teeth, making it easier for users to apply force and rotate, thus reducing the difficulty of adjustment.

[0004] This utility model provides the following technical solution: a rear shock absorber spring preload adjustment wrench, including a handle, the front end of the handle extending to the side to form a support part, the inner side of the support part forming a support surface, and the far end of the support part bending towards the support surface to form a locking tooth.

[0005] As an improvement, the support surface is an arc-shaped surface.

[0006] As an improvement, the locking teeth are oriented towards the center of the arc-shaped surface of the support surface.

[0007] As an improvement, the front end of the handle extends in the opposite direction to the support to form a balancing part, and a support surface is formed on the inner side of the balancing part, and the support surfaces of the support and the balancing part are connected in a flat manner.

[0008] The beneficial effects of this utility model are: by supporting the spring on the outer periphery of the spring adjustment teeth with the support part, and after the locking teeth are engaged with the adjustment teeth, the user can operate the handle to apply force more easily to adjust the spring pressure. It can be easily used in small spaces, reducing the difficulty of adjustment. Attached Figure Description

[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 , 2 Figure 3 shows a specific embodiment of the rear shock absorber spring preload adjustment wrench of this utility model. This embodiment includes a handle 1, the front end of the handle 1 extends to the side to form a support part 2, the inner side of the support part 2 forms a support surface 4, and the far end of the support part 2 is bent towards the support surface 4 to form a locking tooth 3.

[0014] refer to Figure 2 , 3 As shown, the shock absorber spring 01 is mounted on the motorcycle bracket and is protected by the outer cover 03. The housing 03 has an adjustment port 04 corresponding to the adjustment teeth 02, and the adjustment wrench is inserted through the adjustment port 04 for adjustment.

[0015] In use, the support part 2 at the front end of the handle 1 extends into the adjustment port 04. The user inserts the locking teeth 3 into the appropriate adjustment teeth 02 groove, and the support surface 4 of the support part 2 rests against the outer periphery of the adjustment teeth 02. The support surface 4 is located at the front end of the handle 1, thus allowing the user to have a good force application state during operation. The user can adjust the handle 1 by rotating it in the direction to be adjusted. Depending on the size of the opening of the adjustment port 04, the user can repeatedly rotate the wrench to re-insert the locking teeth 3 into the appropriate adjustment teeth 02 groove to adjust the spring pressure. This allows for easy use even in small spaces, reducing the difficulty of adjustment.

[0016] As an improved specific implementation, the support surface 4 is an arc-shaped surface.

[0017] like Figure 1 , 3 As shown, the curvature of the arc surface is matched with the curvature of the outer circumference of the adjustment tooth 02 during the specification design, so that the support surface 4 can better resist and support the outer circumference of the adjustment tooth 02 when the wrench is used, thus ensuring the stability of the force applied when the wrench is used.

[0018] As an improved specific implementation, the locking teeth 3 are oriented toward the center of the arc-shaped surface of the support surface 4.

[0019] like Figure 1 , 3 As shown, this design allows the arc-shaped surface of the support surface 4 to better fit the outer circumference of the adjustment tooth 02 after the locking tooth 3 is engaged in the groove of the adjustment tooth 02, making the force applied by the user more stable when operating the wrench and improving the adjustment efficiency.

[0020] As an improved specific implementation, the front end of the handle 1 extends in the opposite direction to the support part 2 to form a balance part 5, and a support surface 4 is formed on the inner side of the balance part 5, and the support part 2 and the support surface 4 of the balance part 5 are connected in a flat manner.

[0021] like Figure 1 , 3 As shown, the support part 2 and the balance part 5 extend on both sides of the front end of the handle 1 to form a balanced state of the structure, so that the weight of the front end is balanced and the center of gravity is roughly in the middle position. When the user operates the wrench, the arc-shaped support surface 4, which is flat and connected as a whole, supports the outer circumference of the adjustment tooth 02, which can provide a more stable support state and make it easier for the user to apply force.

[0022] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
