[0023] The existing outdoor photovoltaic grid-connected box protective door can only be fixed and opened to one side. In the case of a complex outdoor environment, it is necessary to specially plan a space that is sufficient to open the protective door, which makes the equipment relatively limited when used. In the present application, when the protective door 2 in the corresponding direction needs to be opened, the vertical rod 11 in the corresponding direction is first pulled downward.

[0025] When the space for opening the protective doors 2 on both sides is relatively cramped, pull the arc-shaped supporting plate 15 downward to make enough space on the top of the arc-shaped supporting plate 15, take out the first pin shaft 7, and then insert the first pin shaft 7 into the first rotating sleeve 5 and the second rotating sleeve 6, then open the vertical rods 11 on the two door opening mechanisms, and then open the two door locks 3, and the protective door 2 can be flipped outward to open; by designing a flipping mechanism, the door opening methods are further increased, and the applicability of the photovoltaic grid-connected box 1 outdoors is improved, and the structure is simple and the cost is low.
