Fixing mechanism of stand pipe and front fork vertical bar

Abstract

The invention provides a fixing mechanism of a stand pipe and a front fork vertical bar, which comprises the stand pipe, the front fork vertical bar and a connecting base; the connecting base integrally downwards forms a running casting which can sleeve on the front fork vertical bar, and integrally upwards forms a positioning column which is capable of extending into the stand pipe; a deflectionangle is formed between the central axis of the positioning column and that of the running casting; the pipe port of the running casting is provided with a lower open slot; a lower clamp system whichcan clamp and fix the front fork vertical bar is arranged in the lower open slot; the pipe orifice of the vertical pipe is provided with an upper open slot; an upper clamp mechanism which can clamp and fix the positioning column is arranged in the upper open slot; a lower positioning mechanism is arranged between the running casting and the front fork vertical bar and can prevent the connecting base from rotating relative to the front fork vertical bar; and an upper positioning mechanism is arranged between the positioning column and the stand bar and can prevent the connecting part from rotating relative to the stand pipe. Based on the connection and fixing of the stand pipe and the front fork vertical bar, the invention can also adjust the swing direction of the stand pipe relative to the front fork vertical bar, thereby adjusting the space between a vehicle handlebar on the stand pipe and a cushion.

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,...

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
