Description

Bicycle pneumatic lockable faucet shock absorber Technical field

The invention relates to a shock absorbing device, in particular to a bicycle air pressure lockable faucet shock absorber capable of opening and closing a shock absorbing function.

Background technique

Due to the rise of environmental protection and sportsmanship, the number of people who use bicycles as vehicles for commuting and leisure is increasing. To solve the uneven road surface of bicycles, the vibration of the front wheels is transmitted from the front fork of the bicycle to the bicycle. The handles cause the rider's hand numb and the burden on the wrist to increase, and the relevant practitioners have developed a variety of front suspension structures to improve the rider's bicycle riding experience;

A shock absorbing structure for a bicycle disclosed in the new Taiwan Patent Publication No. TW M419725, which is provided with an elastic member standing upright against the front fork tube, and utilizing the contraction deformation of the elastic member to absorb the rugged road surface. Shock

In addition, other practitioners have also developed a forked suspension riser as disclosed in the Taiwanese new patent case No. TW M454971, which is installed on the upper tube of the front fork of the bicycle and the handle of the bicycle. The body of the bifurcated suspension riser is provided with two fork portions and an elastic body such as a silicone rubber, a rubber or a spring is disposed between the two fork portions, and the vibration transmitted to the handle is absorbed by the deformation of the elastic body; The handle frame suspension structure disclosed in the new Taiwan Patent Publication No. TW M498156 is a buffer member disposed between the riser seat and the handle base. This type of handle frame suspension structure has a cushioning member. It is also made of a soft material such as plastic or rubber, which absorbs the vibration force from the ground;
