Technical Field

[0001] The utility model relates to the technical field of explosion-proof doors, in particular to an explosion-proof door with a steel structure. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment. At present, explosion-proof doors generally include a door frame and two door leaves hinged on the door frame. The rotation axes of the two door leaves are parallel to each other. One door leaf is slidingly provided with multiple bolts, and the other door leaf is provided with a slot for the bolt to be inserted.

When the second fixed shaft is damaged by the explosion impact force, the first connecting plate is unlocked, and the first connecting plate and the second connecting plate are fixed. At this time, the explosion-proof door is opened by using the first fixed shaft, which is convenient for quickly opening the explosion-proof door and improving the rescue speed. It solves the problem that when the door hinge is damaged, it is difficult to open the explosion-proof door, which affects the rescue of the internal personnel and leads to a slow rescue speed.
