Abstract

The invention provides a water-proof and rust-proof distribution box, which belongs to the technical field of distribution boxes. The water-proof and rust-proof distribution box comprises a box body and a box door which are matched, wherein the box door comprises an outer box door and an inner box door; the box body is formed by an upper box surface, a lower box surface, a first side box surface,a second side box surface and a rear box surface in a surrounding mode; the inner box door is hinged with one side of the first side box surface; the outer box door is hinged with the second side boxsurface; a plane is formed between the outer box door and the upper box surface, the lower box surface, the first side box surface and the second side box surface; and the surfaces of the box body andthe inner box door are coated with an insulated paint. Rainwater can be effectively prevented from entering the inner part of the distribution box along the gap between the box door and the box body,the insulated paint coating the surface of the distribution box is water-proof and anti-corrosion, good comprehensive performance is presented through long-time sunshine and rainwater erosion, and the protective effects are good.

Description

technical field [0001] The invention relates to the technical field of distribution boxes, in particular to a waterproof and antirust distribution box. Background technique [0002] The distribution box has become one of the necessary circuit safety protection products in home, industrial, commercial and other decorations. It is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet according to the requirements of electrical wiring or On the screen width, it constitutes a low-voltage power distribution device. The integrated integrated distribution box that appears on the field and in the data mainly includes a cabinet body, a main switch, terminal blocks, ammeter, voltmeter and capacitors located in the cabinet body. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical...
