Problems solved by technology

[0002] Most of the shock-absorbing parts of the commonly used front fork shock absorbers are at the front wishbone. One of the shock absorbers is heavy and unsuitable for the lightweight requirements of bicycles. The upper and lower tubes are connected by bolts, and the assembly is slightly careless When in use, the bolts will loosen, which is prone to safety accidents. It has many three parts, complicated process, and high production cost; another kind of shock absorber is located at the front fork vertical pipe, and the design structure is complicated. Not only the development cost is high, but also It has poor adaptability to the bicycle frame, so it is rare in the market

Abstract

A vibration damper for the front fork of bicycle features that a spring is arranged in a vertical pipe with a longitudinal guide slot on its inner surface, and the vertical pipe of front fork is inserted ni said vertical pipe and hasa slide block matched with said guide slot.

Description

technical field [0001] The invention relates to a bicycle shock absorber. Background technique [0002] Most of the shock-absorbing parts of the front fork shock absorbers commonly used at present are in the front wishbone part. One of the shock absorbers is bulky and unsuitable for the lightweight requirements of bicycles. The upper and lower tubes are connected by bolts, and the assembly is slightly careless When in use, the bolts will loosen, which is prone to safety accidents. It has many three parts, complicated process, and high production cost; another kind of shock absorber is located at the front fork vertical pipe, and the design structure is complicated, which not only has high development cost, but also has high production cost. The adaptability to the bicycle frame is very poor, so it is rare in the market. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a bicycle front fork shock absorber, which has a...
