[0002] Explosion-proof doors are usually composed of explosion-proof window sashes, combined locks, and hardware accessories. The explosion-proof pressure value is usually 20-40PSF. When an explosion or combustion occurs indoors in a building, the indoor gas pressure rises sharply. The explosion-proof door opens the window and releases the pressure through explosion-proof accessories or devices to control the occurrence of the explosion or minimize the degree of damage. The explosion-proof bolts quantify the explosion-proof pressure value and dynamically control the release pressure. However, most of the existing explosion-proof doors are not highly sealed when in use, which may cause air and water leakage in the explosion-proof doors, making it difficult to use the explosion-proof doors.

[0003] In the authorized patent document with the announcement number N217420988U, an explosion-proof door with a waterproof structure is disclosed, including a door frame, an explosion-proof door body is connected to the inner side of the door frame by a hinge, an installation groove a is opened on the outer side of the explosion-proof door body, a mounting plate is embedded and installed on the inner side of the mounting groove a, a limiting mechanism is installed on the outer wall of the mounting plate, an installation groove b is provided on the inner side of the mounting plate, a pressure relief door is connected to the inner side of the mounting groove b by a hinge, the explosion-proof door body can be blocked by a baffle a, and a sealing strip a is embedded in the inner side of the embedding groove a to ensure the sealing of the connection between the explosion-proof door body and the door frame to prevent the explosion-proof door body from leaking air or water, the pressure relief door can be blocked by a baffle b, and a sealing strip b is embedded in the inner side of the embedding groove b to ensure the sealing of the pressure relief door on the inner side of the mounting groove b to prevent the explosion-proof door body from leaking air or water, thereby ensuring that the explosion-proof door can be used well.

[0004] The above device uses a limit plate to block the pressure relief door, which makes it inconvenient to open and close the pressure relief door, increasing the work flow of the staff. Utility Model Content
