[0034] Furthermore, a rectangular block 211 is fixedly provided on one side of the civil defense door body 1, a screw 212 is threadedly inserted on one side of the rectangular block 211, a disc 213 is fixedly provided on one end of the rotating rod 21, the screw 212 is movably inserted into the disc 213, a plurality of circular holes are opened on the outer side of the disc 213, the screw 212 is movably inserted into the circular holes, so as to fix the rotating rod 21 conveniently and prevent the rotating rod 21 from reversing.

[0035] Working principle: When this solution is in use, a toxic gas detector 11 is installed at the top and bottom of one side of the civil air defense door body 1, which can detect the air above and the air below to detect whether the air contains toxic gas. When toxic gas is detected, the toxic gas detector 11 sends information to the controller 12, and the controller 12 controls the alarm 13 to sound an alarm warning to prevent danger and improve safety.

[0036] When the toxic gas detector 11 needs maintenance, the rotating rod 21 can be rotated to drive the bevel gear 1 22 to rotate, and then drive the bevel gear 2 25 and the double-headed threaded rod 24 to rotate, and further drive the slides 28 on both sides to move toward each other, and then drive the plug 29 to move out of the toxic gas detector 11, and no longer fix the toxic gas detector 11. Then, the pull block 113 can be pulled. When the toxic gas detector 11 is moved out of the slot 112, the round head column 34 will be squeezed and the spring telescopic rod 33 will be compressed. Then, the toxic gas detector 11 is moved out of the slot 112, which is convenient for repairing the toxic gas detector 11.

[0037] After the repair is completed, the toxic gas detector 11 can be directly placed into the card slot 112, thereby squeezing the round head column 34 and then compressing the spring telescopic rod 33. When the round head column 34 encounters the circular groove 111, the spring telescopic rod 33 drives the round head column 34 to reset and insert into the circular groove 111, thereby pre-fixing the toxic gas detector 11. Then, the double-headed threaded rod 24 is rotated, thereby driving the slide plates 28 and the plug column 29 on both sides to move in reverse, and then the toxic gas detector 11 is inserted, thereby stably fixing the toxic gas detector 11.

[0038] When ventilation is needed, the threaded column 17 can be rotated to move out of the C-shaped plate 18. At this time, the C-shaped plate 18 and the protective plate 14 fall down under the influence of gravity and leak out of the vent 15 to achieve ventilation.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
