Brake cable for bicycle

Abstract

The invention relates to a brake cable for a bicycle. The brake cable comprises a brake cable body (1) and a steel wire (2), wherein the brake cable body comprises a liner pipe (1.1) and an outer wrapping layer (1.2); the liner pipe (1.1) is arranged inside the outer wrapping layer (1.2); the outer wrapping layer (1.2) is in the shape of a curved spring in the length direction; a metal wire group (2) is arranged in the liner pipe (1.1); the metal wire group (2) comprises a plurality of metal wires; the length directions of the metal wires are the same as the axial direction of the liner pipe (1.1); the metal wires are spirally bent along the length directions of the metal wires. The brake cable for the bicycle disclosed by the invention can automatically retract, and the bicycle is conveniently folded; the metal wire group is high in strength and is unlikely to be damaged.

Description

technical field [0001] The invention relates to a brake cable for a folding bicycle brake system. The utility model belongs to the technical field of bicycle accessories. Background technique [0002] The folding car has the advantages of being foldable, easy to control, and easy to carry. During the folding process, no external tools are needed. The car can be folded or unfolded manually. After folding, it can be stored in the trunk of the car more conveniently. or in the cabin. [0003] In existing folding bicycles, when the vehicle is folded, the brake line cannot be folded, and its length does not change. A longer section is bent outside, and the vehicle is easily caught by external objects during transportation, which affects the folding function of the vehicle; and the existing brake line Because the steel wire in the line lining pipe is a single metal wire, its strength is not enough, which affects the use effect of the brake system.

Problems solved by technology

[0003] In existing folding bicycles, when the vehicle is folded, the brake line cannot be folded, and its length does not change. A longer section is bent outside, and the vehicle is easily caught by external objects during transportation, which affects the folding function of the vehicle; and the existing brake line Since the steel wire in the line lining tube is a single metal wire, its strength will be insufficient, which will affect the use effect of the brake system
