Abstract

The utility model discloses a switch of a folding bicycle. The folding switch of the folding bicycle comprises a handle and a flexible shaft winding piece, wherein the flexible shaft winding piece is hinged with a frame assembly by a hinge pin, the outer wall surface of the flexible shaft winding piece is arc, the handle is connected with the flexible shaft winding piece, the outer wall of the flexible shaft winding piece is provided with a pressing plate for fixing a flexible shaft, and the pressing plate is connected with the flexible shaft winding piece in a detachable way by a bolt; two bolts are used for connecting the pressing plate with the flexible shaft winding piece, and are arranged in a separated way; the but joint surfaces of the pressing plate and the flexible shaft winding piece are both tooth surfaces, and the flexible shaft winding piece is in round pipe shape. The operation of the folding switch is more labor-saving, therefore, the folding of the folding bicycle is more smooth.

Description

The folding switch of folded bicycle

Technical field

The utility model relates to a kind of folding switch of folded bicycle.

Background technology

The switch of traditional folded bicycle, the middle part that is switch is hinged on the frame assembly, one end is a handle, the other end is captiveed joint with flexible axle, by breaking fixed handle off with the fingers and thumb, make flexible axle stretch, thereby driving latching device disconnects, be used for folding, though this kind device is feasible, in practical operation, always exist the power of breaking fixed handle when folding off with the fingers and thumb very big, reason is that folding switch is to adopt pulling force to drive flexible axle to stretch, and pulling force must could realize that the thrust of therefore breaking fixed handle off with the fingers and thumb has just increased by breaking fixed handle off with the fingers and thumb.

Summary of the invention

The purpose of this utility model is to provide that a kind of to operate folding switch more laborsaving, thereby makes the folding folding switch of folded bicycle more smoothly of folded bicycle.

In order to achieve the above object, the technical solution of the utility model is: a kind of folding switch of folded bicycle, comprise handle and flexible axle wrap, the flexible axle wrap is hinged by bearing pin and frame assembly, the outside wall surface of flexible axle wrap is curved, handle is connected with the flexible axle wrap, and the outer wall of flexible axle wrap is provided with the fixedly pressing plate of flexible axle, and pressing plate is removable by screw with the flexible axle wrap and is connected.

Describedly be used for pressing plate and flexible axle wrap bonded assembly screw has two, and arranged apart.

The interface of described pressing plate and flexible axle wrap is the flank of tooth.

Described flexible axle wrap is tubular.

After adopting said structure, because the outside wall surface of flexible axle wrap is curved, and flexible axle is fixedly connected on the flexible axle wrap by pressing plate, when folding operation, handle just drives the flexible axle wrap and rotates, thereby flexible axle just is wound on the flexible axle wrap, make former pulling force, change present take-up force into, take-up force wants specific thrust more laborsaving, thereby makes folded bicycle folding more smooth and easy.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Shown in Fig. 1,2,3,4,5, a kind of folding switch of folded bicycle, comprise handle 1 and flexible axle wrap 2, flexible axle wrap 2 is hinged by bearing pin 5 and frame assembly 3, the outside wall surface of flexible axle wrap 2 is curved, handle 1 is connected with flexible axle wrap 2, and the outer wall of flexible axle wrap 2 is provided with the fixedly pressing plate 4 of flexible axle, and pressing plate 4 is removable by screw 7 with flexible axle wrap 2 and is connected.

Shown in Fig. 1,2,5, for fixation clip 4, the described pressing plate 4 that is used for has two with flexible axle wrap 2 bonded assembly screws 7, and arranged apart.

Shown in Fig. 2,3, can compress flexible axle more in order to make pressing plate 4, described pressing plate 4 is the flank of tooth with the interface of flexible axle wrap 2.

Referring to shown in Figure 1, for convenient folding, described flexible axle wrap 2 is tubular.

Referring to shown in Figure 6, when the utility model uses, flexible axle wrap 2 is hinged on the frame assembly 3 by bearing pin 5, flexible axle 6 is captiveed joint with flexible axle wrap 2 by pressing plate 4, the other end of flexible axle 6 is fixed on the latching device, the outer wall section of flexible axle and flexible axle wrap 2 is reeled, when folding, break fixed handle 1 off with the fingers and thumb, handle 1 drives 2 rotations of flexible axle wrap, is wound on the flexible axle wrap 2 thereby drive flexible axle, thereby makes pulling force be transformed into take-up force, it is laborsaving to break folding switch off with the fingers and thumb, makes folded bicycle folding more smooth and easy.

The utility model is through facts have proved that repeatedly effect is conspicuous.
