Abstract

The invention discloses an internally lockable explosion-proof civil anti-personnel door, which comprises: a door frame part and a door body part, the door body part is installed in the middle position of the door frame part, and when in use, the front hand wheel is manually turned to make the gear rotate, thereby driving the sleeve card to rotate And then drive the runner to rotate, through the rotation of the runner to drive the arc slider to slide and then drive the locking rod to move outward, so that the locking rod stretches out from the protruding hole and inserts into the locking hole to lock the air defense door; when it needs to be opened, through Turn the front hand wheel counterclockwise to reset the wheel, and reset the arc-shaped slider through the return spring, avoiding the situation that the locking lever is difficult to reset; pull the rear hand wheel manually to separate the gear sleeve and the gear inside the sleeve card , and then turning the front hand wheel from the outside cannot open the civil air defense door, so that the civil air defense door is locked and can only be opened from the inside, which increases safety.

Description

technical field [0001] The invention relates to the technical field of civil protection engineering, in particular to an internally lockable explosion-proof civil protection door. Background technique [0002] The civil air defense door is the door of the entrance and exit of the people's protection project. The classification of the civil air defense door is relatively clear. , the role of disaster prevention and mitigation. Most of the traditional civil air defense doors are in the shape of a cuboid, which is easily deformed, and most of them have poor sealing performance and are relatively easy to open. For example, the Chinese invention patent No. 201821091020.4 discloses a civil air defense door. The scheme includes a door frame, and a door frame A hinged door body and a door lock mechanism, a mounting plate is fixed on the bottom of the door body, a rotating shaft is fixed on the mounting plate, a rotating sleeve is sleeved on the rotating shaft, a slot is opened alon...
