Problems solved by technology

[0003] But when the existing bicycle rear derailleur is installed on the bicycle frame, it is all directly installed on the outside of the rear chainstay of the bicycle frame, so that the bicycle rear derailleur is very easy to be bumped or bumped, especially when there is a fall. When driving, the rear derailleur of the bicycle will directly collide with the ground, causing the rear derailleur of the bicycle to be easily damaged. In addition, the existing bicycle rear derailleur is also easy to be damaged artificially

no. 1 example

[0032] refer to figure 1 and figure 2The bicycle 100 includes a bicycle derailleur mounting structure, a wheel 101 and a chain 102 , the bicycle derailleur mounting structure includes a bicycle frame 10 , and the bicycle frame 10 includes a body 1 , a hub rear axle 2 and a derailleur 3 . The main body 1 has two oppositely arranged first fork 11, second fork 12 and two oppositely arranged first fork 13, second fork 14, and hub rear axle 2 is connected to the first fork 11 and the second fork. Between the two forks 12 , the hub rear axle 2 forms a wheel 101 through spokes and rims. One end of the hub rear axle 2 is provided with a cone wheel 103 , and the cone wheel 103 is located between the first fork 11 and the second fork 12 .

[0033] The derailleur 3 is fixedly connected to the first fork 11 , and the derailleur 3 is located between the first fork 11 and the second fork 12 . Preferably, the first flat fork 11 has a flat fork piece 111 , and the flat fork piece 111 is lo...

Abstract

The invention provides a mounting structure for a derailleur of a bicycle and the bicycle. The mounting structure comprises a bicycle frame which comprises a body, a hub rear shaft and a derailleur, wherein the body comprises a first transverse fork, a second transverse fork, a first vertical fork and a second vertical fork, the first transverse fork and the second transverse fork are oppositely arranged, the first vertical fork and the second vertical fork are oppositely arranged, and the hub rear shaft is connected between the first transverse fork and the second transverse fork; and the derailleur is connected with the first transverse fork, the first vertical fork or the hub rear shaft and is located between the first transverse fork and the second transverse fork. The invention further provides the bicycle including the mounting structure. The mounting structure and the bicycle have the advantages that the structures are simple, the mounting structure and the derailleur are not easily broken by human, and the derailleur of the derailleur can be protected.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a bicycle derailleur installation structure and a bicycle comprising the bicycle derailleur installation structure. Background technique [0002] The bicycle rear derailleur is assembled on the rear chainstay of the bicycle frame, and cooperates with the combined speed change gear installed on the bicycle. The rear derailleur moves the chain and meshes with gears of different sizes to realize the gear shifting of the bicycle. When the bicycle is shifted, people push the shift adjuster and pull the cable steel cable to deform the connecting rod structure of the derailleur and move the chain guide to shift, thereby pushing the chain to mesh with different gears. The bicycle rear derailleur is mainly installed on mountain bikes or road bikes to meet people's sports needs. [0003] But when the existing bicycle rear derailleur is installed on the bicycle frame, it is all directly i...
