Abstract

The utility model discloses an improved fixing mechanism stand pipe and front fork montant which comprises a stand pipe, a front fork montant and a foldable connector. The foldable connector consists of an upper foldable seat and a lower foldable seat, wherein one side of one seat is connected with one side of the other seat through a hinge and the other sides of the two seats are foldably fixed through a quick-dismantle subassembly. The upper foldable seat integrally forms a positioning column which can extend into the stand pipe; the lower foldable seat integrally forms a lower casing which can be sleeved on the front fork montant; when the upper foldable seat and the lower foldable seat are buckled with each other, a declination angle is formed between the central axis of the positioning column and the central axis of the lower casing; a lower clamping mechanism which can clamp and fix the front fork montant is arranged at the orifice of the lower casing; an upper clamping mechanism which can clamp and fix the positioning column is arranged at the orifice of the stand pipe; a lower positioning mechanism which can prevent the foldable connector from rotating relative to the front fork montant is arranged between the lower casing and the front fork montant; and an upper positioning mechanism which can prevent the foldable connector from rotating relative to the stand pipe is arranged between the positioning column and the stand pipe. Apart from connecting and fixing the stand pipe and the front fork montant, the improved fixing mechanism can adjust the swinging directions of the stand pipe corresponding to the front fork montant, and meanwhile, the improved fixing mechanism stand pipe and front fork montant is convenient to store after being folded.
