Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The first embodiment is as follows:

referring to figures 1, 2, 3 and 4,

a safety maintenance power box comprises a box body 1 and a box door 2 connected with the box body 1, wherein a plurality of sockets 3 are arranged at the lower end of the box door 2, a switch room door 4 is arranged at the upper end of the box door 2, a waterproof device 5 is arranged outside the sockets 3, a power main switch 6 is arranged in the box body 1, and a transparent plastic shell 7 is sleeved on the power main switch 6; the power supply is needed to be used for overhauling the power supply box, and the transparent plastic shell is arranged on the power supply main switch, so that the on-off of the power supply of the overhauling power supply box can be conveniently observed; the safety of maintenance is improved. When the main switch of the power supply is checked, the door of the switch chamber needs to be opened firstly.

As a preferred embodiment of the present invention, the waterproof device includes a base and a cover plate 53 connected to the base, the base is disposed at the periphery of the socket, the base includes an outer edge 51 disposed at the upper end and extending outward and two inclined surfaces 52 disposed at both sides, and the base, the two inclined surfaces and the outer edge are integrally formed.
