Embodiment
[0033] Embodiment: a kind of explosion-proof type air defense door, as figure 1 As shown, it includes a door body 1 and a plurality of steel balls 2 filled inside the door body 1; a rectangular frame 3 is also provided in the door body 1; Both vehicles are tangent; steel ball 2 is hollow inside, and metal melt 4 is poured in the gaps of multiple steel balls 2; after solidification, multiple steel balls 2 can be connected into a whole, and metal melt 4 The steel ball 2 and the frame 3 can also be connected as a whole, so the steel ball 2, the frame 3 and the molten metal 4 together form the door body 1; when the door body 1 is impacted by the explosion, the steel ball 2 is first deformed because the interior of the steel ball 2 is hollow , the deformation of the steel ball 2 can cause the surface of the door body 1 to sag, and then can produce the effect of releasing the impact force received, reducing the impact of the explosion on the door body 1, so that the door body 1 can ...

The invention discloses an explosion-proof civil defense door, and belongs to the field of civil defense engineering. According to the technical scheme, the explosion-proof civil defense door is characterized by comprising a door body and a plurality of steel balls filling the door body, wherein the circumferential surfaces of the plurality of steel balls are tangent, gaps among the steel balls are filled with a molten metal, and after the molten metal is solidified, the plurality of steel balls can be connected into a whole. According to the civil defense door, the problem that a conventionalcivil defense door is low in explosion impact resistance is solved, and the effects that the resistance, to the explosion impact, of the civil defense door is improved, and the civil defense door isprotected against reduction of the protective effect of the civil defense door are achieved.
Description
technical field [0001] The invention relates to the field of civil air defense engineering, more specifically, it relates to an explosion-proof civil air defense door. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. There are ordinary single and double protective airtight doors and airtight doors, and a variety of civil air defense equipment with single and double protective airtight doors and airtight doors with living thresholds. [0003] It can be referred to the Chinese utility model patent whose authorization announcement number is CN209384965U, which discloses a civil air defense door with good thermal insulation effect, including civil air defense door body a, civil air defense door body b and rack, said civil air defense door body a and civil air defense door Body b is respectively installed in the inside of the door fra...
