Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present utility model, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the relative positional relationship, movement conditions, etc. between the components shown in the figure below are changed, if the specific posture changes, the directional indication will also change accordingly.

The utility model provides a metal armored switch cabinet.

In this embodiment, referring to Figures 1-3, the metal armored switchgear includes a cabinet body 1 and a cabinet door 2 hinged on the cabinet body, and the pressure relief port on the top of the cabinet body 1 is provided with a pressure relief cover 3. It also includes a pressure relief cover 4 and a lifting spring 5.
