Bicycle-shock absorb

Abstract

The invention provides a bicycle shock absorber including a frame and a shock absorber; the frame comprises a seat mounting tube, a front support tube, an upper main tube, a front fork mounting tube,a lower main tube, a fixing block, a rear fork lower tube, a rear fork upper tube and rear support tube; at one end of that front support tube, the seat mount tube is welded, a low main tube is weldedat the other end of the front support tube; the front support tube is welded to the main tube close to seat mounting tube, the other end of the upper main tube is welded with one end of the front fork mounting tube, the other end of the front fork mounting tube is welded with one end of the lower main tube, the other end of the lower main tube is welded to the rear support tube, a lower main tubeis hinged with a rear support tube at the weld position, the lower tube of the rear fork and the upper tube of the rear fork are welded, the other end of the upper tube of the rear fork is welded with the rear support tube, and the shock absorb comprises a movable block, a hydraulic cylinder, a spring and a piston rod, wherein the movable block is a disk, and two projections are symmetrically arranged on one side of the movable block with respect to the center. The invention has the beneficial effect that the vehicle body and the human body are prevented from being injured.

Description

technical field [0001] The invention belongs to the field of bicycles, in particular to a bicycle shock absorber. Background technique [0002] Although many existing bicycles have shock-absorbing structures, the shock-absorbing structures of most bicycles are mainly for the shock absorption of the front wheels. The key is that the force of the bicycle is more biased towards the rear wheels, and the pressure on the rear wheels is greater than that of the front wheels. , the rear wheels are more prone to puncture and damage, and now most of the bicycle seats are biased towards the rear, which increases the force on the rear wheels, and the burden on the rear wheels is greater, especially in rough terrain. When the vibration is too large, it is more likely to be damaged, resulting in personal safety problems. Contents of the invention [0003] The object of the present invention is to provide a bicycle shock absorber with simple structure, strong compression resistance and ...
