Door structure capable of preventing and removing smoke

Abstract

The invention discloses a door structure capable of preventing smoke and removing smoke, comprising a door body, an upper baffle plate, a lower baffle plate, a driving assembly and an adjusting assembly; an accommodation cavity is arranged in the door body, and openings are opened at both upper and lower ends of the door body; The assembly includes a first transmission shaft and a second transmission shaft. The other end of the first transmission shaft is sheathed with a first bevel gear, and the upper end of the second transmission shaft is sheathed with a second bevel gear meshed with the first bevel gear. The lower end of the transmission shaft is covered with a driving gear; it also includes two water bags located in the accommodating cavity, the water bags communicate with the liquid inlet channel through a hose, and a solenoid valve is also arranged at the inlet of the liquid inlet channel. In the event of a fire accident, the water bag, the movable upper baffle and the lower baffle can be used to effectively close the gap between the upper and lower ends of the door, the door frame and the ground, and to extinguish the flames around the door to a small extent. , to reduce the speed of fire smoke entering the room, so as to buy more rescue time for residents.

Description

technical field [0001] The invention relates to the technical field of home building materials, in particular to a door structure capable of preventing and removing smoke.
