Cover body split type distribution box

Abstract

A cover body split type distribution box comprises a bottom box capable of accommodating electrical appliances. The bottom box is equipped with a surface cover in a matching manner. According to the main technical characteristics, the surface cover is provided with a cover door through an arranged rotary shaft, and the cover door can be rotationally opened; the surface cover is further provided with an assembling opening, and the assembling opening is provided with an internal cover with an operation window; knocked-off threading holes are preformed in the side walls of the bottom box; and a rectangular combined groove is formed around each knocked-off threading hole, and connecting ribs are preformed between the combined grooves. The cover body split type distribution box has the advantages that the split type internal cover is used, so that once the e distribution box is assembled and fixed, the internal cover can be dismounted for repair and maintenance, the surface cover does not need to be dismounted, and no influences are caused to external walls; in addition, the reserved circular holes are combined with external square holes, the sizes of most wire pipe diameters are covered, and the distribution box is prevented from being rudely sawn and damaged due to too small preformed holes.

Description

technical field [0001] The invention relates to the field of power distribution equipment, in particular to a cover-detachable power distribution box. Background technique [0002] Distribution boxes are often used to install switchgear, meters, protectors and other equipment, so the distribution box must follow the principles of safety, reliability, practicality and economy and should be easy to operate, maintain, test and monitor, and connect; however, the existing distribution box They are all directly covered with the upper cover, and the cover of the distribution box is installed during construction, and then the wall of the house is decorated. After the decoration is completed, the cover is often removed when maintenance is required. The wall skin on the edge of the cover also cracks or falls off directly, affecting the appearance.

[0002] Distribution boxes are often used to install switchgear, meters, protectors and other equipment, so the distribution box must follow the principles of safety, reliability, practicality and economy and should be easy to operate, maintain, test and monitor, and connect; however, the existing distribution box They are all directly covered with the upper cover, and the cover of the distribution box is installed during construction, and then the wall of the house is decorated. After the decoration is completed, the cover is often removed when maintenance is required. The wall skin on the edge of the cover will also crack or fall directly, affecting the appearance

In addition, when wiring, the size of the wire tubes is different, and the distance between the reserved wire tube holes in the general distribution box is different. In actual operation, it is difficult to align the wire tubes with the reserved wire tube holes on the distribution box. Fixing or sawing off the distribution box is time-consuming and labor-intensive
