Movable combined wire rack

Abstract

The invention provides a movable combined wire rack, which comprises a U-shaped bracket and two bases. The U-shaped bracket is formed by bending a tube body. More than one retractable and restorable bump is arranged at each of the two ends of the U-shaped bracket. The retraction direction of each bump is perpendicular to the length direction of the tube body. Each base comprises a bottom plate and a limiting tube. The bottom end of each limiting tube is fixed on the corresponding bottom plate. Limiting holes matched with the retractable and restorable bumps are arranged on the sidewalls of the limiting tubes. The two ends of the U-shaped bracket are inserted into the upper ends of the limiting tubes of the bases respectively, and the bumps are clamped into the limiting holes of the limiting tubes to detachably connect the U-shaped bracket and the basses. More than three mounting holes for riveting are formed in the bases outside the limiting tubes. A plurality of shortcomings of the prior art are overcome. The movable combined wire rack has the advantages of convenience for mounting, removal and the lap winding of an insulating tape.

Description

technical field [0001] The invention relates to the manufacturing technology of railway locomotives, in particular to a movable combined wire frame. Background technique [0002] There are two types of wiring devices for control lines and power lines on railway locomotives: wire slots and wire racks. Due to the large space occupied by wire slots, they are generally used to organize the wiring of larger wire harnesses. Compared with wire slots, wire racks have lower space requirements, better effect of fixing wire harnesses, and more flexible use. Therefore, wire racks are often used for wiring on scattered wire harnesses and places with limited space on railway locomotives. [0003] The traditional wire frame is directly welded on the car body after being folded into a U shape by a cylindrical iron bar or a flat iron bar, which has the following disadvantages: [0004] (1) Its position and size cannot be changed casually. When adding parts to the already designed locomoti...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the gap between the wiring part of the traditional wire frame and the car body is only 70mm at most. In addition, the space where the wire frame is used is generally relatively small. It is time-consuming and laborious to wrap the wire frame with insulating tape.
