Improvement on adjustable bicycle head vertical rod

Abstract

The invention discloses an adjustable bicycle head vertical rod. Two sleeves which are used for conveniently fixing a front fork vertical rod and a bicycle head cross handle in an insertion sleeved way respectively are arranged at the two ends of the bicycle head vertical rod; a sleeve orifice of at least one end is a slot-shaped pipe orifice; at least one open slot which can conveniently clamp a pipe fitting through a clamping mechanism is formed at the slot-shaped pipe orifice along the axial direction; an adjustment block which is detachable and is provided with a crescent cross section is arranged on the lateral part of the slot-shaped pipe orifice; when the adjustment block is inserted into one side on the inner part of the slot-shaped pipe orifice, a circular orifice by which the pipe fitting is convenient to fasten is formed by the crescent cross section and the slot-shaped pipe orifice; the sleeve with the slot-shaped pipe orifice consists of a left half pipe orifice and a right half pipe orifice; the left half pipe orifice is integrated with the bicycle head vertical rod; two open slots are formed by folding the left half pipe orifice and the right half pipe orifice; and the side face of the adjustment block consists of a convex arc-shaped surface which can be tightly attached to the inner side of the slot-shaped pipe orifice and a concave arc-shaped surface which can be tightly attached to the surface of the bicycle head cross handle. By the bicycle head vertical rod, the distance between the front fork vertical rod of which the two ends are fixedly connected with each other and the bicycle head cross handle can be adjusted, so that the distance between the bicycle head cross handle and a bicycle cushion can be adjusted, and a humanized design is realized.

Description

technical field [0001] The invention relates to a connection and fixing structure of bicycle pipe fittings, in particular to an improvement of the front vertical bar which can adjust and fix the length between the front fork vertical bar and the front handlebar. Background technique [0002] The front fork vertical tube on the bicycle and the front handlebar are connected and fixed by the front vertical rod (the two ends of the front handlebar form a handle). Specifically, one end of the front vertical rod is sleeved and fixed to the front fork vertical rod And the other end also wears a sleeve and is fixed on the handlebar at the front of the car. At present, the distance between the handlebar 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 women. . Contents of the invention [0003] In...

Problems solved by technology

At present, the distance between the handlebar 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 women.
