Abstract

A telescopic bicycle handle bar, a steering lamp is arranged at the front end of a lamp holder, a lamp holder pipe clamp is clamped at the top end of an inner pipe of the handle bar, and a brake handle is sleeved in the lamp holder for fixing; the self-rebounding button switch is arranged at the top end of the inner tube of the handlebar and is connected and controlled with the steering lamp through a wire; the clamping piece is connected with the pipe clamp through a shaft lever, and buckling resilience is realized under the action of a spring; the pipe clamp assembly is sleeved on the outer handlebar pipe and enables the clamping piece to be clamped into a clamping hole at one end of the outer handlebar pipe; the telescopic length can be adjusted by adjusting the number of the inserted parts of the inner tube of the handlebar, and the limit of the inner tube and the outer tube can be realized. The utility model has the advantages that: accords with human engineering, makes forearm radius and ulna be in the parallel state at the in-process of riding, and two hands finger is the globular shape of embracing of stretching little bent, effectively avoids radius and ulna alternately oppression to cause the arm tendon uncomfortable, also can furthest alleviate palm sweat and finger fatigue. The transverse telescopic function saves transverse space when in carrying or idling, and the width can be adjusted in real time according to personal preference or road conditions when in riding.

Description

Telescopic bicycle handlebar

Technical Field

The utility model relates to the field of bicycle structures, in particular to a telescopic bicycle handle.

Background

At present, the conventional bicycle handlebar is usually of a fixed structure and cannot be transversely shortened, so that inconvenience in carrying or boxing is caused. The handlebar of part bicycle though can shorten horizontal width through folding the form of buckling perpendicularly, but product structural strength greatly reduced leads to having dangerous hidden danger when using, also can not continue to realize the function of controlling of riding after folding simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the problems and particularly provides a telescopic bicycle handle.

The utility model provides a telescopic bicycle handlebar, which is characterized in that: the telescopic bicycle handlebar comprises a steering lamp 1, a lamp holder 2, a brake lever 3, a self-rebounding button switch 4, a handlebar inner tube 5, a tube clamp 6, a clamping piece 7, a spring 8, a handlebar outer tube 9, a vertical tube 10, a connecting rod 11, an outer sleeve 12, an inner telescopic tube 13, a large cap screw 14, a handle 15, an expansion support nut 16 and a shaft rod 17;

wherein: the steering lamp 1 is arranged at the front end of the lamp holder 2, the lamp holder pipe clamp 6 is clamped at the top end of the handlebar inner pipe 5, and the brake handle 3 is sleeved in the lamp holder 2 for fixing;

the self-rebounding button switch 4 is arranged at the top end of the inner handlebar tube 5 and is connected and controlled with the steering lamp 1 through a wire; the clamping piece 7 is connected with the pipe clamp 6 through a shaft lever 17, and realizes buckling rebound under the action of a spring 8;

the pipe clamp 6 assembly is sleeved on the outer handlebar pipe 9 and enables the clamping piece 7 to be clamped into a clamping hole at one end of the outer handlebar pipe 9; the clamping piece 7 is pulled backwards, the other end of the handlebar inner tube 5 is inserted into the handlebar outer tube 9, a row of clamping holes of the handlebar inner tube 5 and clamping holes of the handlebar outer tube 9 are always kept on the same straight line, the telescopic length is adjusted by adjusting the number of the inserted parts of the handlebar inner tube 5, when the clamping holes at proper positions of the inner tube and the outer tube are opposite, the clamping piece 7 is loosened and clamped into the clamping holes of the handlebar inner tube 5 and the outer tube 9, and the limiting of the inner tube and the outer tube is realized; the handlebar outer tube 9 assembly is centrally arranged in a tube clamp of the stand tube 10 and fixed;

the inner telescopic pipe 13 is arranged in a pipe clamp of a handle 15, a large cap screw 14 penetrates through a screw hole of the handle 15, one end of the large cap screw is screwed into an expansion support nut 16, the expansion support nut 16 and the inner telescopic pipe 13 are inserted into the outer sleeve 12 together, and the expansion support nut 16 is pulled to clamp the inner end of the inner telescopic pipe 13 to realize expansion limiting locking after the large cap screw 14 is screwed; the outer sleeve 12 and the riser 10 are connected and fixed by a connecting rod 11.

The pipe clamp 6 assembly is sleeved on the handlebar outer tube 9, and the clamping piece 7 can be inserted into a clamping hole at one end of the handlebar outer tube 9 and locked through a bolt.

The utility model has the advantages that:

the telescopic bicycle handlebar provided by the utility model is in line with human engineering, the radius of the forearm and the ulna are in a parallel state in the riding process, fingers of two hands are in a stretched and slightly curved embracing ball shape, the discomfort of arm tendons caused by the crossed compression of the radius and the ulna is effectively avoided, and the palm sweating and the finger fatigue can be relieved to the greatest extent. The transverse telescopic function saves transverse space when in carrying or idling, and the width can be adjusted in real time according to personal preference or road conditions when in riding. Meanwhile, the handlebar has high structural strength and ensures safety in use.
