The implementation principle of this application embodiment people's air defense door does: the door body 2 is rotated towards the direction of the doorframe 1, and the cover plate 5 rotates around the door body 2 towards the direction far away from the inner wall of the bottom edge of the doorframe 1 under the action of the trapezoidal block 6, so that the cover plate 5 is positioned above the boss 4; continue to be close to door body 2 in the door frame 1 rotation, butt rod 9 slips to first inclined plane 7 from second inclined plane 8 this moment, and butt rod 9 slides along first inclined plane 7 orientation near 1 base inner wall direction of door frame, and apron 5 rotates near 4 directions of boss towards under the effect of gravity this moment, and the interact of butt rod 9 and first inclined plane 7 makes apron 5 slowly cover to close on boss 4.
After 5 lids of apron close on boss 4, start electromagnet 10, electromagnet 10 carries out the electromagnetism to magnetic stripe 11 and adsorbs, make 5 stable sealed lids of apron close on boss 4, electromagnet 10 is when adsorbing magnetic stripe 11, the inseparable pressfitting of apron 5 is on boss 4, balloon 12 is extruded this moment, balloon 12 can be clogged the clearance between apron 5 and the boss 4, guaranteed the sealing performance between apron 5 and the boss 4, and then improved the sealing performance when the people's air defense door is closed.
Simultaneously, when the door body 2 was in the closure state, sucking disc 20 steadily adsorbed on the door body 2, realized the sealed of the 2 both sides of door body, avoided gas to spill over in the clearance between the door body 2 and the strip shaped plate 18, gasbag 21 can be stuffed to the clearance between the door body 2 and the 1 top inner wall of door frame, avoids gas to spill over from between the door body 2 and the 1 top inner wall of door frame.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
