When the box cover 2 needs to be closed, an operator can push the box cover 2 to slide along a direction perpendicular to the opening direction of the opening so that the box cover 2 is covered on the opening of the box body 1, and the positioning convex part 52 slides into the positioning concave part 51, and then the positioning convex part 52 is prevented from being separated from the positioning concave part 51 by the locking limiting part 6. Therefore, the electrical box 100 of the embodiment of the utility model can change the movement mode of the box cover 2 in the opening and closing process from rotation to sliding along the direction perpendicular to the direction of the opening, so that the box cover 2 occupies a small space on the front side of the opening of the box body 1 when opening or closing, the risk that the device on the front side of the opening of the box body 1 of the electrical box 100 obstructs the opening of the box cover 2 is reduced, even if other devices are arranged on the front side of the opening of the box body 1, the electrical box 100 can be opened or closed smoothly, and the electrical box 100 can be conveniently overhauled or debugged by an operator.

In the present embodiment, as shown in fig. 1 and 2, the box body 1 includes a mounting upright plate 11, two side plates 12 disposed on both sides of the mounting upright plate 11, and a top plate 13 disposed on the top of the mounting upright plate 11. As shown in fig. 3, the box cover 2 includes a plate body 21, two first flanges 22 provided on opposite sides of the plate body 21, and a second flange 23 provided on the top of the plate body 21. The positioning projection 52 is provided projecting on the outer surface of the side plate 12. The positioning recess 51 is provided on the first flange 22. This enables the positioning protrusion 52 to be cut into the positioning recess 51 and enables the plate body 21 of the box cover 2 to cover the opening of the box body 1 when the first flange 22 of the box cover 2 is sleeved on the mounting vertical plate 11 of the box body 1 and the second flange 23 abuts against the top plate 13, and the first connecting structure 3 is aligned with the second connecting structure 4. In other embodiments, the positioning protrusion 52 may be disposed on the first flange 22, and the positioning notch 51 may be disposed on the outer surface of the side plate 12. Preferably, flanges are further provided on the sides of the two side plates 12 and the top plate 13 away from the vertical mounting plate 11, and the flanges can be in surface contact with the plate body 21 when the box cover 2 is covered on the box body 1, so as to enhance the stability of installation.
