Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof doors and windows, and in particular to an explosion-proof device. Background Art

[0002] Explosion-proof doors are usually used in industrial and civilian factories, boiler rooms, hazardous materials warehouses, military warehouses, pharmaceutical companies and other places. When an explosion or combustion occurs indoors in a building, the gas pressure in the room rises sharply. The explosion-proof doors use explosion-proof accessories or devices to open the windows and release the pressure to control the occurrence of the explosion or minimize the degree of damage.

[0003] According to the Chinese patent publication number: CN217558170U, a pressure-sensitive explosion-proof door and window with novel structural design includes a window frame, a fixing plate is fixedly connected to the top and bottom of one end of the outer wall of one side of the window frame, and a first door and window is connected between the two fixing plates through a pin shaft, a hinge is fixedly connected to one end of the first door and window, and a second door and window is fixedly connected to one end of the hinge, both ends of the top of one side of the window frame are connected to transmission wheels through bearings, and the outer walls of the two transmission wheels are transmission-connected to transmission belts, one end of one of the transmission wheels is provided with a driving mechanism, and the bottom of the outer wall of the transmission belt is fixedly connected to a mounting sleeve.

[0004] The above scheme still has the following disadvantages: when the explosion pressure in the door is too high during the use of this explosion relief device, the first door and window and the second door and window are opened by the motor, the thermal expansion rod and the conductive block to relieve the explosion. After the explosion relief is completed, the first door and window and the second door and window are reset by pulling the handle, so that the door and window cannot be buffered during the explosion relief, which can easily cause the door and window to be damaged and unable to be automatically reset. For this reason, we propose an explosion relief device. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an explosion relief device, which solves the problem that when the pressure generated by the explosion in the door is too large during use, the first door and window and the second door and window are opened by a motor, a thermal expansion rod, and a conductive block to relieve the explosion. After the explosion relief is completed, the first door and window and the second door and window are reset by pulling the handle, thereby failing to buffer the doors and windows during the explosion relief, causing the doors and windows to be easily damaged and unable to be automatically reset.
