Bicycle Wire Sleeve Structure

Abstract

The invention relates to a sleeve structure for bicycle guide lines. The sleeve structure comprises an outer cover pipe and a plurality of projections, wherein the plurality of the projections are circularly disposed in the inner wall of the outer cover pipe; the outer cover pipe is provided with a first terminal and a second terminal; and the projections are cone-shaped and inclines toward the second terminal, so that the guide lines can penetrate in from the first terminal and penetrate out from the second terminal, and the projections force the periphery of the guide lines tightly; the outer wall of the outer cover pipe is provided with a plurality of screw thread-like grooves which are disposed at the first terminal of the outer cover pipe; an oil seal is sleeved in the second terminal of the outer cover pipe; the oil seal can allow the guided lines to penetrate through; the inner wall of the outer cover pipe and the outer wall of the oil seal abut against each other; the inner wall of the oil seal is provided with at least one oil storage tank; and the outer cover pipe is made of metal materials or plastic materials. The sleeve structure for the bicycle guide lines structure employs a plurality of convex ring structures to force the periphery of the guide lines tightly, and provides the function of fastening the guide lines.

Description

technical field [0001] The invention relates to a bicycle wire casing structure, in which a bump arranged on the inner wall of an outer cover tube presses the outer circumference of the wire to achieve the effect of fastening the wire. Background technique [0002] Now is the era of green environmental protection, bicycles are easy to emerge in this era, and become the trendy and environmentally friendly means of transportation. Bicycle brake wires and shift wires are one of the important devices. It is an important part that affects safety during riding, so it cannot be ignored. Usually, one end of the brake wire and shift wire is arranged on the relevant positioning structure of the front and rear forks on the bicycle frame, and the other end is wrapped around the front tube and beam tube of the frame. It is assembled on the transmission and the brake lever, and the exposed inner cable is protected by an outer tube, and the tube body is a metal tube or a plastic tube. Howe...

Problems solved by technology

[0003] However, after long-term exposure to sunlight and exposure to wind and rain, the plastic material of the plastic pipe is easily brittle and lacks toughness. It is easy to cause damage and rupture of the pipe body at the connection between the elbow and the positioning structure or when it is bent, resulting in the exposure of the inner wire. Corrosion of the inner cable will affect the safety of riding

[0004] However, the wire inserted into the plastic tube is not tightly sealed between the inner wall of the plastic tube and the wire, so external dust, fine substances or car oil can easily enter through the gap, affecting the brake line and shifting line so that the sensitivity is reduced or even When the brake is pressed and the gear is changed, the brake line and the shift line need to be pulled to make them slide back and forth, and because there is no structure to hold the brake line, it is easy to cause the brake line and the shift line to slip. Constitutes a risk factor when riding a bicycle and is prone to danger
