It is responsible for transmitting the force applied by the brake handle so that the brake clamps the wheel, thereby achieving the braking function. The outside of the brake cable generally has a wire tube, which is used to protect the brake cable.

[0003] The existing brake line pipe has a single overall function, which is only to protect the internal brake line. In addition, it has no other functions. With the increasing demand, ordinary brake line pipes can no longer meet the use needs. Therefore, there are great limitations in actual use, and there is room for improvement. Utility Model Content

During use, the pipe body is limitedly connected with other positions of the vehicle body through the connecting assembly to prevent the pipe body from being scattered; the protective layer is placed inside the pipe body, and the outer wall of the protective layer is bonded to the inner wall of the pipe body by hot melting or glue to achieve connection. During use, the wear of the inner wall of the pipe body caused by the brake line is reduced by the protective layer; an external thread groove is provided on the outer wall of one end of the pipe body, and an internal thread portion is provided on the inner wall of the other end of the pipe body, and the internal thread portion is threadedly connected to the external thread groove. When the length of the pipe body needs to be extended, the internal thread portion can be threadedly connected to the external thread groove on another pipe body to achieve stable installation.

[0006] Preferably, the length of the connector sleeved on the tube body is greater than the length of the external thread groove, so that the external thread groove can be completely covered while avoiding damage to the external thread groove.

[0007] Preferably, the connecting assembly includes a ring sleeved on the tube body, a connecting plate welded on the ring, and a through hole formed on the connecting plate. During use, connecting pieces such as bolts or wires pass through the through hole and are wrapped around the vehicle body, thereby achieving limited installation of the tube body.

[0008] Preferably, the inner diameter of the collar is greater than or equal to the outer diameter of the tube body, so that the collar can slide on the tube body, and the longitudinal section of the through hole is rectangular, which is convenient for penetration.

[0009] Preferably, the material of the protective layer is the same as that of the tube body, and both are made of rubber. The inner diameter of the protective layer is larger than the diameter of the brake line, thereby ensuring the normal passage of the brake line.

[0010] Preferably, a regular polygonal sleeve is provided at one end of the connector, and the regular polygonal sleeve is tightly wrapped around the tube body through deformation.

[0011] Preferably, one end of the protective layer is flush with an opening at one end of the tube body, and a distance is left between the other end of the protective layer and the internal threaded portion to ensure normal screwing of the external thread groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] In the utility model, the current single brake line can be assembled and connected to achieve the purpose of extending the brake line and meet the use requirements of brake lines of different lengths. There is no need to replace the inconvenience caused by the specified length of the brake line. At the same time, it is also convenient to limit the installation of the brake line to avoid scattering outside. At the same time, the built-in protective layer can reduce the wear of the brake line on the inner wall of the brake line tube, thereby improving the overall functionality of the brake line tube and improving the shortcomings of the existing brake line tube in use.
