Description

Mechanical stroke fixing device for bicycle shock absorber

Technical Field

The utility model relates to the technical field of bicycle parts, in particular to a mechanical stroke fixing device of a bicycle shock absorber.

Background

Along with the popularization and the promotion of the existing mountain cross-country activities, more and more people like riding mountain bicycles. The front fork of the mountain bike is divided into a shock-absorbing part and a non-shock-absorbing part, and the common mountain bike uses the shock-absorbing front fork. When the front fork is in the non-dead-lock state, it can absorb vibrations, for example cross country, the partly vibrations of going downstairs, but the front fork is in the dead-lock state, and this partly vibrations just can not be absorbed completely to reduce the momentum of power, have fine protection effect to the automobile body, especially in cross country riding, reduce the degree of difficulty of riding.

When the front fork is locked, the pedaling force can be completely used for advancing power in climbing or flat road riding instead of absorbing a part of force by the shock absorption effect of the front fork, so that the front fork can be locked to easily ride on a flat road and climb the slope. The problem of unsmooth riding caused by dead locking mechanical friction usually exists after the dead locking front fork of the prior art is assembled.
