Weather-tight airtight fireproof door
The invention relates to a weather-tight airtight fireproof door, comprising a door frame and a door plate. A group of corresponding edges of the door frame and door plate are in hinged fit. The door is characterized in that one edge, far away from the connecting edges, of the door plate is provided with an upper door lock, a middle door lock and a lower door lock arranged from top to bottom, a first transmission mechanism is connected among the upper door lock, the middle door lock and the lower door lock, the inner side of the door plate is provided with rod bases close to two edges, one rod base corresponds to the middle door lock in position, a crank is hinged to each rod base, and a presser rod is connected between the outer ends of the two cranks, the middle door lock is provided with a second transmission mechanism, the crank on the rod base corresponding to the middle door lock is in linked fit with the second transmission mechanism, and the second transmission mechanism is also in linked fit with the first transmission mechanism. By mounting the weather-tight airtight fireproof door on a wall of a chamber interface of a ship, weathertightness, airtightness and fireproofing of the door can be guaranteed, the door is convenient to lock and unlock, and emergent escape of people in the chamber is facilitated.
