Agile type bicycle brake structure

Abstract

The invention discloses an agile type bicycle brake structure, comprising a shaft casing, a rotary shaft, an expanding brake device, a transfer bar, a connector, a transmission arm, a hex nut, a frame fixing end, an upper return spring, steel balls, an inner expanding brake sheet, an expanding brake shoe, a lower return spring, an expanding brake box, a brake box cover and an eccentric shaft, wherein the shaft casing is connected with the rotary shaft; the rotary shaft is fixed on the expanding brake device; the transmission arm is located at the right side position of the expanding brake device; the connector is installed on the transfer bar; the upper return spring is fixed at the position above the steel balls; the brake box cover is arranged at the left side position of the expanding brake box. The interior of the agile type bicycle brake structure is made of an alloy material, the service life is long, the steel ball material is good and is not likely to break, the expanding brake shoe is good in quality and is not likely to wear, the problem of high cost is avoided, and the transmission effect of the inner expanding brake sheet is good, the response speed is rapid, prompt parking is realized, the practicability is more remarkable, and bicycling is safer and more reliable.

Description

technical field

[0001] The invention belongs to the technical field of bicycles, in particular to an agile bicycle brake structure. Background technique

[0002] With the prosperity of the economy, the continuous improvement of people's living standards, the development of production technology is getting better and better, and people's use of their time is becoming more and more demanding. In life, we have higher and higher requirements for equipment. We hope to be able to Through the innovation of equipment to improve the working efficiency of the equipment, reduce working hours, improve the efficiency of use, so that it can maximize its value. With the development of science and technology, bicycles have become the largest number of means of transportation in our country.

[0003] Taking the bicycle brake structure as an example, there are a series of problems in the bicycle brake structure on the market, such as the steel ball is not good, it is easy to break, it will be...
