Modified fixing mechanism of riser and front fork vertical bar

Abstract

A modified fixing mechanism of a riser and a front fork vertical bar consists of the riser, the front fork vertical bar and a folding joint, wherein one side of the folding joint is connected through a hinge, the other side consists of an upper folding seat and a lower folding seat which are folded and fixed by a quick release component; a positioning column which can extend into the riser is integrated with the upper folding seat, a lower casing which can be sleeved on the front fork vertical bar is integrated with the lower folding seat; when the upper folding seat is fastened with the lower folding seat, a deflection angle is between the central axes of the positioning column and the lower casing; the pipe orifice of the lower casing is provided with a lower clamping mechanism which can clamp and fix the front fork vertical bar; the pipe orifice of the riser is provided with an upper clamping mechanism which can clamp and fix the positioning column; a lower positioning mechanism which can prevent the folding joint from rotating relatively to the front fork vertical bar, is arranged between the lower casing and the front fork vertical bar; and an upper positioning mechanism which can prevent the folding joint from rotating relatively to the riser, is arranged between the positioning column and the riser. By using the modified fixing mechanism, the riser and the front fork vertical bar can be connected and fixed, the swinging direction of the riser to the front fork vertical bar can be adjusted and the mechanism can be conveniently folded for storage.

Description

technical field [0001] The invention belongs to the fixing structure of the connection part between the standpipe and the front fork vertical rod, in particular to a detachable and fixed connection structure between the standpipe and the front fork vertical rod. Background technique [0002] On the bicycle, the front fork vertical bar and the standpipe are connected and fixed through the beam tube, specifically, one end of the beam tube is used to accommodate the front fork vertical bar, and the hanging screw provided in the middle of the front fork vertical bar is inserted into the beam tube and rotated. Fasten the nut to realize the connection and fixation of the front fork vertical bar and the beam tube. After the other end of the beam tube accommodates the riser, the beam tube is clamped and fixed by the bolt and nut, or the quick release group. At present, the distance between the handlebar on the riser and the bicycle seat cushion is designed according to men or women,...

AI Technical Summary

Problems solved by technology

At present, the distance between the handlebar on the riser and the bicycle seat cushion is designed according to men or women, so that it can be reflected in men's or women's bicycles. However, the difference in human arm length determines that the same bicycle cannot be adapted to all men. or lady
