Description

Link type shock absorber seat tube

This creation is related to a kind of shock-absorbing seat tube structure, especially a connecting rod-type shock-absorbing seat tube that changes the installation position of the elastic body so that the elastic body can achieve the shockproof effect with a small stroke space.

Bicycle is a commonly used means of transportation. It uses human pedaling as its power source, without the use of electricity or gasoline. It has an environmentally friendly concept and is very suitable for use as a general means of transportation or leisure sports equipment.

In the current environment, there are few completely flat roads. When riding a bicycle, encountering rugged and uneven roads, or climbing on a rocky road, a road with a drop, the bicycle will suffer In order to solve this problem, most bicycles are equipped with shock absorbers to absorb the vibration force, so that the user can feel more comfortable when riding.

Most of the shock absorbers are installed on the seat tube under the handlebars, front forks, rear forks and seat cushions of the bicycle. For the shock absorbers currently installed on the seat tube, such as the Republic of China Patent Publication No. M572852, An elastic element is arranged inside the seat tube so as to achieve the effect of shockproof by the elastic element. However, the conventional method of installing an elastic element inside the seat tube for shock-proofing, the elastic element must have a larger travel space to achieve the shock-proof effect, and the elastic element is covered by the seat tube, and its elasticity cannot be tight.
