Bicycle handle folding mechanism

Abstract

The invention relates to a bicycle handle folding mechanism which is simple in structure, easy to unfold and lock and firm in locking. The bicycle handle folding mechanism comprises a handle seat, a left handle rod, a right handle rod and a locking mechanism. The handle seat is composed of a connecting base capable of being connected with a bicycle stand pipe, an upper extending plate and a lowerextending plate. The handle rod is provided with an open arc-shaped groove; when the handle is unfolded, the handle ends of the handle rods rotate and are unfolded towards the two sides respectively,a connecting rod of the locking mechanism is clamped into the open arc-shaped grooves in the other ends of the left handle rod and the right handle rod, and the other ends of the left handle rod and the right handle rod are located between the upper extending plate and the lower extending plate in an up-down overlapped mode. According to the handle folding mechanism, the left handle and right handle overlapping locking technology is adopted, and the effects that after the bicycle folding handle is unfolded, a locking operation is easy and firm, and the handle is not loosened are achieved.

Description

technical field [0001] The invention relates to a bicycle handle folding mechanism, which has the advantages of simple structure, easy unfolding and locking operation, and firm locking of the handle. Background technique [0002] Bicycles provide people with a popular way of transportation, sports, leisure, and fun. As the concept of low-carbon environmental protection is widely recognized in China and the world, bicycle travel is becoming more and more popular. Traditional bicycles, especially bicycles focused on sports and competitions, are often larger and heavier, which are not suitable for casual and portable short-distance transportation and leisure purposes, so folding bicycles are born in due course. Owing to will install brake handle on the handlebar of bicycle, other accessories such as speed change handle, and consider people originally to the length of handlebar because of riding comfort, bicycle handlebar is the largest part of bicycle transverse dimension like ...

Problems solved by technology

The advantage of this method is that the unfolded handle lock is very firm, but the disadvantage is also obvious, the operation is too complicated. Strictly speaking, this is not a folding handle, but a handle that can be disassembled as needed

Another kind of folding handle is to use a sleeve with a tapered structure to block the left and right handles respectively; this kind of folding handle is easy and fast to operate, but due to the need to unlock it by hand, it is generally necessary to design a large gap during production. In this way, the handle has a loose feeling after unfolding the lock
