Abstract

A brake cable for a folding bicycle comprises an inner cable (2) and a cable sleeve (1). The inner cable (2) is disposed inside the cable sleeve (1). The cable sleeve (1) is in a spring curve form. Because the brake cable for a folding bicycle can automatically retract during folding of a folding bicycle. After the bicycle is folded, the brake cable no longer stays around the frame at excessive length, so that the bicycle stays simple and neat, has a simple structure, and is easy to use.

Description

Brake line for folding car

Technical field

[0001] The utility model belongs to a folding bicycle accessory, and particularly relates to a brake wire for a folding vehicle.

Background technique

[0002] The folding cart has the advantages of being foldable, easy to handle, and easy to carry. It does not need to use external tools during folding, and the vehicle can be folded or unfolded by hand. After folding, it can be conveniently stored in the trunk of the car. Or board the inside of the chassis.

[0003] The structure of the current folding bicycle is basically the same as that of the ordinary bicycle, and the structure of the brake line is also the same. The front end of the brake line is connected with the brake lever, and then the end of the brake is extended along the handlebar riser and the frame tube to the rear brake. The entire intermediate process of extension, the brake line is attached to the outer circumference of the frame, and is fixed by the rope buckle provided on the outer periphery of the frame so as to be in close contact with the outer circumference of the frame to avoid loosening or being hooked by external objects. However, when the vehicle is folded, the brake wire cannot be folded, its length does not change, and the longer section is bent outside, and the vehicle is easily caught by an external object during transportation, which affects the folding function of the vehicle.

[0004] Therefore, in order to overcome the above shortcomings, some producers hide the brake line in the frame tube body, but as is generally known, the brake line needs to be repaired or replaced as the service life increases, and the brake line is hidden in the frame. The inside of the tube will bring greater inconvenience to maintenance and replacement.

[0005] How to develop a brake wire for use in an easy folding vehicle has become a technical problem that a person skilled in the art needs to solve.

Utility model content

[0006] The problem to be solved by the present invention is to provide a brake line for a folding vehicle, which can automatically retract and facilitate folding of the vehicle.

[0007] The utility model is realized by the following technical solutions:

That is, a brake wire for a folding vehicle, comprising a sleeve and a core, wherein the core is disposed in the sleeve, wherein the sleeve is in a spring curve shape; the brake line is provided with a reel, the sleeve Coiled on the reeling tray; the reeling reel is provided with a buckle; the sleeve is an elastic plastic tube.

[0008] The beneficial effects of the utility model are:

1. The utility model discloses a brake line for a folding vehicle, which can automatically retract while folding with the folding vehicle. After the vehicle is folded, the brake line will not stay too long on the outer circumference of the frame, so that the vehicle maintains a simple appearance and the brake line Automatic retraction eliminates the need for complicated connectors, eliminates the need for complicated operation procedures, and is simple in structure and easy to use.

[0009] 2. The bushing of the brake wire is made into a spring curve. Under the normal use state of the folding car, the brake wire maintains the normal extended use state. Under the folding and folding state of the folding car, the brake wire is automatically retracted into a spring shape, and the bushing is automatically The flexible plastic tube makes the brake line retractable and stretchable.

[0010] 3. The brake wire is provided with a winding reel, and the casing is wound around the winding reel, which further enhances the flexibility of automatic retracting and stretching.

[0011] 4. The reeling coil is provided with a buckle. This design enables the reeling reel to be easily and firmly assembled on the frame without fixing it by special fixing parts. It can be removed when not needed, and the operation is simple. Easy to use.

detailed description

[0013] Figure 1-2 The utility model relates to a brake wire for a folding vehicle, which comprises a sleeve 1 and a core 2, wherein the core 2 is arranged in the sleeve 1, and the sleeve 1 has a spring curve shape, and the brake line is in a normal use state. Maintaining the normal stretched state, the brake line is automatically retracted in a spring-like state when the folding cart is folded and folded.

[0014] In order to improve the flexibility of automatic retraction and extension of the brake wire, the sleeve 1 is made of an elastic plastic tube, and the core 2 is expanded and contracted with the expansion and contraction of the sleeve 1.

[0015] In the present solution, the winding wire reel 3 can be provided for the brake wire, and the casing 1 is wound around the winding reel.

[0016] The reeling reel is a disk for loading and winding. The disc has a self-locking device and has an automatic cable discharging function. After the cable is pulled out, the self-locking device works, and the cable is locked and stops. If you want to retract the cable, you need to pull out a cable again. The cable passes through the self-locking device, the self-locking device is released, and the cable is automatically retracted.

[0017] The reeling reel 3 can be fixed on the frame together with the brake wire manufacturing. After the vehicle is folded, the excess brake wire can be flexibly and smoothly retracted into the reeling reel without manual operation.

[0018] The winding reel 3 can also be provided with a buckle, which is fastened to the frame by the buckle. When the vehicle is folded, the reeling reel 3 is assembled to the frame, and the excess brake wire is manually wound around the reeling reel 3, and the operation is relatively simple; when the vehicle is in normal use, the reeling reel can be retracted. 3 Remove from the frame.

[0019] It should be noted that the above embodiments are merely preferred embodiments of the present invention. For those skilled in the art, any equivalent or similar replacements are included in the present invention in accordance with the working principle of the present invention. The scope of protection of utility models.
