AI Technical Summary

Technical Problem

In the prior art, the traditional frame has a high- and low-tube welding to the front pipe, which has a weight-required frame with a risk of strength, its appearance is not beautiful, and its wiring is set outside the frame, which is prone to wear and tear after a long time, resulting in poor brakes.

Method used

The headless tube frame design is adopted, and the wiring is carried out inside the pipe fittings. The lower pipe is firmly connected to the side wall of the five-way and extends to the bottom of the five-way. A reinforcement box is installed to support the connecting parts, and the brake line is connected from the inside of the pipe fittings through the front inlet and the rear inlet port to avoid the wire being placed on the outer wall.

Benefits of technology

It achieves the aesthetics and strength of the frame, while protecting the brake wire from wear and avoiding the problem of ineffective brakes.

Abstract

The utility model relates to a headless tube type frame. The bottom bracket comprises a bottom bracket, the surface of the bottom bracket is fixedly connected with a lower pipe, a middle pipe, a lower fork and a reinforcing box respectively; a lower pipe is fixedly connected to the side wall of a bottom bracket, extends out of a cavity, is connected to the bottom of the bottom bracket and is arranged in an arc shape, a reinforcing box is fixedly connected to the rear surface of the bottom bracket and is used for supporting connecting pieces such as the lower pipe and a middle pipe, a front wire inlet is formed in the position, located in the cavity of the lower pipe, of the reinforcing box, and the reinforcing box penetrates through the bottom bracket. The front wire inlet is used for wiring, the wire is a brake cable, the side wall of the reinforcing box and the connecting position of the lower fork are provided with a rear wire inlet, a cavity is also formed in the lower fork, the rear wire inlet is also used for wiring and is connected from the cavity in the lower fork, and the brake cable can be connected from the interior of the pipe fitting through the front wire inlet and the rear wire inlet. Without arranging wires on the outer wall of the pipe fitting, the whole frame is attractive, and the wires are protected from being abraded.
