Bicycle head vertical rod improvement

Abstract

The invention discloses a bicycle head vertical rod improvement, which is arranged between a front fork vertical rod and a bicycle head horizontal handlebar, a lower pipe orifice capable of sleeving on the front fork vertical rod is formed at one end of a bicycle head vertical rod, an upper pipe orifice capable of sleeving on the bicycle head horizontal handlebar is formed on the other end of the bicycle head vertical rod, the upper pipe orifice is a grooved pipe orifice, a detachable clamping assembly is arranged on the lateral of the grooved pipe orifice, and comprises two lateral clamping blocks, a middle clamping block arranged between the two lateral clamping blocks and a bolt, the two lateral clamping blocks are respectively provided with opposite inclined surfaces, the middle clamping block is provided with a conical surface corresponding to the inclined surfaces of the two lateral clamping blocks, the bolt movably penetrates one lateral clamping block and the middle clamping block, and then is screwed and fixed in the other lateral clamping block, and the middle clamping block is provided with a grooved hole, and therefore the middle clamping block can conveniently slide outside relative to the two lateral clamping blocks. According to the invention, the distance of connecting and fixing the front fork vertical rod and the bicycle head horizontal handlebar can be adjusted, so as to adjust the distance of the bicycle head horizontal handlebar and a bicycle saddle, a humanization design is realized, and the bicycle head vertical rod and the bicycle head horizontal handlebar are convenient and reliable to fix.

Description

technical field [0001] The invention relates to a connection and fixing structure of bicycle pipe fittings, in particular to an improved structure of a front fork vertical bar and a front handlebar which can be fixed, and the length between the fixed front fork vertical bar and the front handlebar can be adjusted. Background technique [0002] The front fork vertical rod on the bicycle and the front handle are connected and fixed by the front vertical rod (the two ends of the front handle form a handle), specifically, one end of the front vertical rod is sheathed and fixed on 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 wo...
