AI Technical Summary
The existing bicycle front brake outer line pipe is easily worn by hole wall burrs during threading, resulting in a degradation of brake performance and a cumbersome threading process.
A front brake external line tube is designed, introduced through the side wall of the fork steering tube, and then bound to the outer surface of the fork leg after passing through the fork sleeve. The fork leg has linear grooves and bayonets, which facilitates semi-hidden wiring and avoids passing through the fork leg side wall hole.
Improves the safety and reliability of the brakes, prevents burrs from wear on the hole wall, simplifies the threading process, and enhances the reliability and durability of the brakes.

Abstract
Description
Technical Field
[0001] The utility model relates to a bicycle brake outer cable tube, in particular to an improved front brake outer cable tube, which can ensure safe and reliable braking and prevent burr wear. Background Art
[0002] Currently, the front brake cable is routed from the front brake handlebar, passed through a hole in the sidewall of the front fork steering tube, and then into the front fork sleeve (the lower end of the front fork steering tube is connected and fixed to the front fork sleeve). It then passes through the interior of the front fork sleeve, into the interior of the front fork leg, and then out through a hole in the sidewall of the lower fork leg before being routed to the front brake caliper. Since the front fork leg is welded to the front fork sleeve, the existing threading method requires the front brake cable to be repeatedly threaded in and out of the front fork leg. This is not only cumbersome, but also prone to wear and tear from burrs on the hole wall, which can damage the front brake cable and affect braking performance. Summary of the Invention
[0003] In order to make up for the above deficiencies, the utility model provides a front brake outer line tube, which can not only improve safety and reliability, but also prevent burrs on the hole wall from wearing, and has practical value.
[0004] The technical solution of the utility model is achieved as follows: a front brake outer cable tube is introduced through the side wall of a front fork steering tube, the outer cable tube passes through a front fork sleeve connected to the lower end of the front fork steering tube and is then led out and is bound to the outer surface of a front fork leg.
[0005] As an improvement of the present invention, the side of the front fork leg is provided with a linear groove, which facilitates the semi-hidden routing of the front brake outer line tube along the linear groove on the front fork leg.
[0006] As an improvement of the present invention, the front fork legs are made of metal material and the linear groove is formed integrally therewith.
[0007] As an improvement of the present invention, the linear groove is provided with a plurality of bayonet holes arranged at intervals, which facilitates the insertion of the front brake outer line tube into the linear groove.
[0008] The beneficial technical effect of the present invention is: a front brake outer cable tube, which is introduced through the side wall of the front fork steering tube, and the outer cable tube is led out after passing through the front fork sleeve connected to the lower end of the front fork steering tube, and is restrained to the outer surface of the front fork fork leg. Furthermore, the side wall of the front fork fork leg has a linear groove, which facilitates the semi-hidden routing of the front brake outer cable tube along the linear groove on the front fork fork leg. It does not need to pass through the front fork fork leg from the upper and lower side wall holes of the front fork fork leg, thereby preventing burrs on the wall holes from being worn. The routing is done along the linear groove on the side wall of the front fork fork leg, which can not only improve the safety and reliability of braking, but also prevent burrs on the wall holes from being worn, and has practical value.

[0015] Combine Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the following is a detailed statement:
[0016] A front brake outer cable pipe, the front brake outer cable pipe 3 is introduced through the side wall of the front fork steering tube 1, the outer cable pipe 3 passes through the front fork sleeve 2 connected to the lower end of the front fork steering tube 1 and is then led out and bound to the outer surface of the front fork fork leg 4, and the side of the front fork fork leg 4 has a linear groove 41, which facilitates the front brake outer cable pipe 3 to be semi-hidden along the linear groove on the front fork fork leg (such as Figure 4 As shown in FIG, the front fork leg 4 is made of metal and integrally forms the linear groove 41 .
[0017] The linear groove is provided with a plurality of bayonet holes arranged at intervals, which facilitates the front brake outer line pipe to be clamped into the linear groove.
[0018] After such design, the front brake outer cable is led out from the front brake handle, introduced through the side wall hole of the front fork steering tube 1, passed through the front fork sleeve 2 connected to the lower end of the front fork steering tube 1, and then led out, and constrained to the outer surface of the front fork fork leg 4. There is no need to pass through the front fork fork leg from the upper and lower side wall holes of the front fork leg to prevent wear of burrs on the wall holes. The cable is routed along the linear groove on the side wall of the front fork fork leg, which can not only improve the safety and reliability of braking, but also prevent wear of burrs on the wall holes, and has practical value.
