Fireproof door

Abstract

The invention discloses a fireproof door. The fireproof door comprises a door frame obliquely arranged at an escape passage opening, wherein a door panel is obliquely arranged in the door frame, a door panel installation cavity is formed in middle of the door frame, and the bottom of the door panel is connected with the door frame in a hinged mode; the top of the door panel is a movable end, the movable end of the top of the door panel is fixed by a magnetic suction door lock, the magnetic suction door lock is arranged at the top of the door frame, and the magnetic suction door lock is arranged on the side away from an escape passage; and more than one through hole is formed in the top of the door frame, a guide shaft rod is arranged in a wall body of each through hole in an embedded mode,each of the guide shaft rods is internally provided with a guide shaft hole, and each of the guide shaft holes is internally provided with a drawing wire. The fireproof door has two opening and closing modes, in the case of not hampering normal use, when in a fire environment, the door panel can be directly pressed down and opened, at the moment, water stored inside can be sprayed out by the drawing wires, so that an entire inlet and outlet cavity is covered with water mist, thus a fire source can be effectively isolated, and a door body is prevented from burning.

Description

technical field [0001] The invention relates to a door, in particular to a fireproof door. Background technique [0002] In some emergency escape routes, a large number of fire doors are often installed. These fire doors are generally only opened for use when escaping. Therefore, fire doors are doors that guarantee life and must have very good fire safety. However, the current fire doors Generally, it can only temporarily prevent fire. After burning for a long time, the entire door body will be burned out, causing the fire to spread rapidly. And when flame gathers near the fire door, it is difficult to operate the fire door at this moment, and then cannot open the fire door and escape. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of fireproof door, which adopts the door panel with inclined design. When a fire occurs, it can be operated without hands, and the whole door panel can be dumped by stepping o...

[0002] In some emergency escape routes, a large number of fire doors are often set up. These fire doors are generally only opened for use when escaping. Therefore, fire doors are doors that guarantee life and must have very good fire safety. However, the current fire doors Generally, it can only temporarily prevent fire. After a long time of burning, the entire door body will be burned out, causing the fire to spread rapidly.

And when the flames gather near the fire door, it is difficult to operate the fire door at this time, and then it is impossible to open the fire door and escape
