Abstract

The invention provides an electrical equipment box, comprising a box body plate and side plates, wherein the box body plate is connected with the side plates, T-shaped chutes for mounting bolts are formed in inner surfaces of the box body plate and the side plates, the T-shaped chutes comprise first rectangular grooves and second rectangular grooves, the first rectangular grooves and the second rectangular grooves are formed in a penetration manner, the first rectangular grooves and the second rectangular grooves are formed in the surfaces of the box body plate and the side plates, and the widths of the first rectangular grooves are less than the widths of the second rectangular grooves. According to the electrical equipment box provided by the invention, by forming the T-shaped chutes formounting bolts in the inner surfaces of the box body plate and the side plates, the opposite edges of the bolts can be firmly clamped, the traditional double-faced mounting operation form of bolts and nuts is changed into single-faced operation, so that the installation is convenient and fast.

Description

technical field [0001] The invention belongs to the field of rail transit electrical equipment, in particular to an electrical equipment box. Background technique [0002] With the expansion of city size and population increase, the problem of traffic congestion in the city has become more and more serious. Since urban rail transit is fast, safe, and does not occupy ground space, it is necessary to vigorously develop urban rail transit. Become an important way to solve the traffic problem in the city. [0003] Therefore, with the development and progress of urban rail transit, higher requirements have been put forward for the current electrical equipment. The hole is installed on both sides. This installation method is relatively time-consuming and complicated, and at the same time, it cannot achieve a good sealing effect on the inside of the electrical equipment box. [0004] In view of this, it is necessary to provide an electrical equipment box, which can facilitate and...
