The advantages and positive effects of the present invention are: compared with the prior art, the new bicycle rear fork bracket adopts bearing connection between the upper fork and the lower fork and the assembly body, and this way can realize the up and down movement of the upper fork, And it is detachable, which can easily replace the damaged parts. Secondly, the thickness of the bearing fixing groove is smaller than that of the assembly. This design can fix the bolt cap more firmly, and it is connected with an elastic telescopic pump between the upper fork and the lower fork. The upper fork A spring stopper and a telescopic shaft are installed in the middle, which can reduce the bumps caused by the vibration of the car body. What's more, the whole component is made of titanium alloy, so the design of the entire rear fork bracket ensures the quality of the product and saves the product. The maintenance cost can be reduced, and the damage to the car body can be reduced and the personal safety of the rider can be guaranteed.

Preferably: the assembly is respectively connected to the lower fork and the upper fork through bolts, and the assembly can be separated from the lower fork and the upper fork.

Preferably: the bearing fixing groove and the assembly are integrally designed, and the thickness of the bearing fixing groove is smaller than that of the assembly.

Preferably: the upper fork is located on the upper side of the elastic telescopic pump.

Preferably: the telescopic shaft is arranged inside the spring, and the telescopic shaft can be stretched from inside to outside.

detailed description

In order to further understand the content of the invention, characteristics and effects of the present invention, the following examples are described in detail as follows:

Please refer to Fig. 1, a novel bicycle rear fork bracket of the present invention, including an assembly body 1, a fixing ring 2, a bearing fixing groove 3, a bearing device area 4, a triangular hole 5, a lower fork fixing shaft 6, a lower fork 7, and a lower fork Fixed block 8, elastic telescopic pump 9, upper fork fixed shaft 10, upper fork 11, upper fork fixed block 12, spring stopper 13, telescopic shaft 14 and spring 15. in

The assembly 1 is arranged on the left side of the lower fork 7 and the upper fork 11, and the assembly 1 includes a fixing ring 2, a bearing fixing groove 3 and a triangular hole 5, the fixing ring 2 is located on the upper side of the assembly 1, and the bearing fixing groove 3 is arranged on the assembly 1, and the bearing fixing groove 3 is located around the bearing device area 4, the bearing device area 4 is arranged inside the assembly body 1, and the triangular hole 5 is fixedly arranged on the assembly body 1.

The lower fork fixing shaft 6 is connected to the assembly body 1, the lower fork 7 is connected to the assembly body 1 through the lower fork fixing shaft 6, the lower fork fixing block 8 is located on the upper side of the lower fork 7, and the elastic telescopic pump 9 is respectively connected to the lower fork fixing block 8 through bolts and upper fork fixed block 12;
