detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the box body 1 is the main body of the present invention, and a base 12 is provided at the bottom of the box body to facilitate the support of the box body. The front side of the box body is provided with a box door 11, one end of the box door is hinged with the box body, and the other end of the box door is provided with a lock door assembly between the box body.

As shown in Figure 3, the door lock assembly mainly includes a locker 2, a slide plate 21, a latch 22, a pull ring 24 and a spring 25, and as shown in Figure 4, the locker is a hollow cylindrical structure, and the inner wall of the box A mounting hole 13 is arranged on the top, and the locking device is arranged in the mounting hole. A slide plate 21 is slidably installed in the inner cavity of the locker, a latch 22 is fixed on the slide plate, an inclined surface 23 is provided at the active end of the latch, and a pull ring 24 is provided at the driving end of the latch, between the slide plate and the locker A spring 25 is arranged between the inner walls, and under the action of the spring, the active end of the bolt is placed outside the locker. The inboard of the free end of the door is provided with a plug 14, and the plug is provided with a jack 15, and the relative fixing of the door and the casing can be realized when the active end of the bolt is placed in the jack. When the box door is closed, the plug contacts the inclined surface and then overcomes the elastic force of the spring to squeeze the latch until the latch is aligned with the jack, and the active end of the latch can be inserted into the jack. The free end of the plug is provided with a circular arc to reduce the friction between the plug and the plug.

As shown in Figure 5, a number of beams 4 arranged up and down are arranged in the inner cavity of the box body, and the two ends of the beams are installed on the slide rail 3 through bolts. fixed on the inner wall of the box. As shown in FIG. 6 , the beam is a sheet metal part, and the beam is provided with a long hole 41 for installing an electric energy meter, a current transformer, and the like.
