Abstract

The utility model relates to a sleeve-pipe rotating type folding handlebar, which comprises a middle connecting part, a sleeve pipe and an inner sleeve, wherein the sleeve pipe and the inner sleeve are symmetrically arranged at the left and the right and are connected together in an inserting manner. The upper end of the sleeve pipe is provided with a handle, and a pin is installed on the sleeve pipe. The pin penetrates through the inner sleeve and the sleeve pipe. The lower end of the inner sleeve is inlaid with a stop, and a tension spring is arranged in the inner sleeve. One end of the tension spring is connected with the pin, and the other end of the tension spring is connected with the stop. The lower end of the sleeve pipe is provided with a positioning block, and a positioning convex block matched with the positioning block is arranged on the outer wall of the inner sleeve. A sliding groove for the pin to slide is also arranged on the wall of the inner sleeve, and the sliding groove is composed of a cross groove and a vertical groove which are communicated. The sleeve-pipe rotating type folding handlebar has simple structure, convenience for folding and safe and reliable use, and is suitable for various folding bicycles and folding electric bicycles.

Description

Sleeve pipe rotary type folding handlebar

Technical field

The utility model relates to the bicycle field, specifically, relates to a kind of sleeve pipe rotary type folding handlebar that is used on the bicycle.

Background technology

Present bicycle (containing Electrical Bicycle) develops to miniaturization and folding direction; For the ease of carrying; Various mini foldable cycles have become the main flow in market gradually, but the present foldable structure of bicycle handle bar more complicated is still used inconvenient; Poor stability after particularly Folding Bicycle is opened is easy to generate potential safety hazard.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, folding convenient, safe and reliable sleeve pipe rotary type folding handlebar.

The technical scheme that realizes above-mentioned purpose is: a kind of sleeve pipe rotary type folding handlebar comprises middle interconnecting piece and left-right symmetric and is plugged on sleeve pipe and interior cover together that the upper end of sleeve pipe has handle; Pin is installed on the sleeve pipe, and this pin pass in the cover and sleeve pipe, the lower end of interior cover is embedded with silently; In the cover in be provided with extension spring, an end of this extension spring is connected with pin, the other end with silently be connected; The lower end of sleeve pipe has position block; Have the protruding block in the location that cooperates with this position block on the outer wall of interior cover, also have the chute that supply and marketing slides on the wall of interior cover, this chute is made up of translot and vertical slot two parts of being communicated with.

After adopting technique scheme, sleeve pipe rotary type folding handlebar adopts pin and the two location of block, and stability is strong; Safe and reliable, only need pull out back rotary carriage handle, can reach folding effect; When using bicycle; Outwards (vertical sleeve) or make progress (horizontal sleeve pipe) one pushes away gently, can open the location, uses very convenient.It is little that the utility model also has folding rear bar shrink space, the slick and sly no corner angle of assembling back part, advantage elegant in appearance.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

Shown in Fig. 1 ~ 16, a kind of sleeve pipe rotary type folding handlebar comprises middle interconnecting piece 5 and left-right symmetric and is plugged on sleeve pipe 1 and interior cover 2 together; The upper end of sleeve pipe 1 has handle 6, and pin 1-1 is installed on the sleeve pipe 2, and this pin 1-1 passes interior cover 2 and sleeve pipe 1; In cover 2 lower end be embedded with silently 3; In cover be provided with extension spring 4 in 2, an end of this extension spring 4 is connected with pin 1-1, the other end with silently 3 be connected; The lower end of sleeve pipe 1 has position block 1-2; Have the protruding block 2-1 in the location that cooperates with this position block 1-2 on the outer wall of interior cover 2, also have the chute 2-2 that supply and marketing slides on the wall of interior cover 2, this chute 2-2 is made up of translot and vertical slot two parts of being communicated with.

Shown in figure 23, the translot of chute 2-2 and horizontal angle are 0 ~ 8 °.

The use step of the utility model is following:

One, folding

1, like Fig. 1,4,5, shown in 6, the handlebar of vertical sleeve structure as long as sleeve 1 up one draw folded inward.

2, shown in Figure 17 ~ 22, the handlebar of horizontal sleeve structure if with sleeve pipe 1 to lira, folding downwards again.

Two, open and use

1, like Fig. 1,4,5, shown in 6,, sleeve pipe 1 one is pushed away outward for the handlebar of vertical sleeve structure, pin 1-1 along in the chute 2-2 that puts move, can open the location.

Shown in Figure 17 ~ 22, for the handlebar of horizontal sleeve structure, sleeve pipe 1 upwards one is carried, the chute 2-2 that puts in the pin 1-1 edge moves, and can open the location.

The utility model is applicable to various folding bicycles and folding electric bicycle.
