Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor thinks that the upper and lower lock heads move up and down by locking the hand wheel to complete the locking and unlocking of the civil air defense door, and the sealing of the threshold also needs to control the flipping of the flip beam by turning the lifting handle. The door is sealed, and the sealing of the lock door and the threshold requires two operations, and the process is relatively cumbersome
