Bicycle lead casing

Abstract

The invention provides a bicycle lead casing. The bicycle lead casing comprises an internal tube, a fibrous layer and an external covering layer, the internal tube is used for the pass-through of a bicycle lead, the fibrous layer is formed by arranging a plurality of strands around the internal tube and winding around the internal tube, the plurality of stands are prepared by using glass fibers, a plurality of recessed joints positioned among the plurality of strands are formed on the external surface of the fibrous layer, the external surface of the fibrous layer is covered with the external layer, and the recessed joints are filled up by parts of the external covering layer. By adopting the above technical scheme, the bicycle lead casing has a good bend toughness and a good durability.

Description

technical field [0001] The invention relates to a wire sleeve for vehicles. Background technique [0002] Generally speaking, the braking system or the speed change system of the bicycle are connected to the vicinity of the handlebar by a brake line or speed change line for the user to control. Perform operations such as clamping and braking. [0003] Therefore, bicycle wires such as brake lines or shifting lines are indispensable, and the bicycle wires must be connected from the handlebars to the actuation area (such as the brake mechanism), and must extend for a certain distance through the vehicle frame on the way, and, in order to Cooperating with the frame, the bicycle cable usually needs to be properly bent. However, it is difficult to accurately transmit power when the curved bicycle cable is pulled, and it may even get stuck and fail, which has become a hidden concern for riding safety. [0004] In this regard, the industry has developed a sleeve for bicycle wires,...

Problems solved by technology

[0005] Generally speaking, the casing includes an inner layer wound by metal wires and a cladding layer wrapped around the wires. In order to provide better weather resistance and structural strength, the cladding layer is often used Polypropylene is used as its material. However, the cable structure made of metal is rigid but not flexible enough. Excessive bending may cause breakage. It is still insufficient as a sleeve that must be bent.
