SHOCK ABSORBER

摘要

A shock absorber includes an outer pipe, an inner pipe and an elastic rubber cushion. The outer pipe is a hollow structure. The inner pipe is disposed in the outer pipe to define a receiving space between the inner and outer pipes, and is a hollow structure rotatable with respect to the outer pipe. The elastic rubber cushion is disposed in the receiving space and fixed to an inner wall of the outer pipe and an outer wall of the inner pipe, respectively. The shock absorber works in rotation manner to absorb shocks, which not only enables the shock absorber to absorb forces in al directions, but also reduces the size of the shock absorber. Besides, the shock absorber uses the elastic rubber cushion as a buffer, which produces no noise during the process of shock absorbing.

1. A shock absorber comprising:
an outer pipe being a hollow structure; an inner pipe disposed in the outer pipe to define a receiving space between the inner and outer pipes, the inner pipe being a hollow structure rotatable with respect to the outer pipe; and an elastic rubber cushion being disposed in the receiving space and fixed to an inner wall of the outer pipe and an outer wall of the inner pipe, respectively; wherein the elastic rubber cushion includes a first elastic member and a second elastic member which are made of different materials, whereby the elastic rubber cushion has different coefficients of elasticity.
