Abstract

The invention discloses a bicycle brake device. The bicycle brake device comprises a first brake arm and a second brake arm, both of which are fixedly provided with brake blocks in the middle, wherein adjusting components are arranged at the front ends of both the first brake arm and the second brake arm; each adjusting component comprises a brake arm return spring which is made of an alloy and adopts a linear structure; a bent pipe seat is arranged at the rear end of the first brake arm; a line locking screw for locking a brake line is arranged at the rear end of the second brake arm; and when a bicycle is braked, the bent pipe seat and the line locking screw are pulled by the brake line, so that the first brake arm and the second brake arm rotate around a brake fixing seat to enable the brake blocks and bicycle rims to perform friction braking. The first brake arm and the second brake arm are formed through the stamping technology and provided with reinforced ribs for guaranteeing the strength. Compared with the like product in the market, such structure is attractive in appearance and high in production efficiency. The bicycle brake device has the advantages of sensitiveness in returning, economy, practicality, wide application range, quickness in assembly and attractive appearance.

Description

technical field [0001] The invention relates to the technical field of brake devices for locomotives, in particular to a brake device for bicycles. Background technique [0002] V-shaped braking device is widely used in bicycles due to its low price and simple structure. In the current bicycle V-brake system on the market, the reset of the V-brake is controlled by the brake arm return spring on the V-brake. The brake arm return spring generally adopts hard metal to cooperate with the spring adjustment screw to regulate the spring force. However, due to the problem of the material of the brake arm return spring, the existing brake arm return spring will loose its elastic force after a long time, resulting in unstable braking and affecting safety. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bicycle brake device with sensitive reset, economic benefits, wide product applicability, quick assembly and beautiful ...
