Problems solved by technology

[0003] As long as the conventional fire doors block the fire through steel or steel-wood doors with flame retardants, they can prevent the fire from expanding within a certain period of time, but in a closed room where important equipment is installed, it is neither possible to transfer the equipment nor easy to extinguish the fire. , even if the fire door can temporarily stop the fire, it is still easy to cause equipment burns and property damage

Abstract

The invention discloses a fire-fighting door device. The fire-fighting door device comprises a door plate and a door frame arranged in the circumferential direction of the door plate, the outer side of the door frame is arranged in a pre-arranged installation door hole on a wall in a matched mode, and one side of the door plate is hinged to the side wall of the door frame. A rotating shaft is arranged at the position, near the door plate, in the top cavity of the door frame in the width direction of the door frame, a reset spring and an mounting cylinder sleeve the rotating shaft in sequence,one end of the reset spring is connected with the rotating shaft, and the other end of the reset spring is connected with the mounting cylinder. A fire-proof screen is arranged on the outside of the mounting cylinder in a rolling mode, an iron block is arranged at the end part of the outermost layer of the fire-proof screen, and a passageway for the iron block to pass through is arranged at the top of the door frame. An electromagnetic coil is arranged in the top cavity of the door frame, and the electromagnetic coil is electrically connected with preset uninterruptible power supply in the wall. According to the fire-proof door structure, the fire-proof screen is additionally arranged on the outside of the door plate, and the transfer of fire can be blocked for a longer time.

Description

technical field [0001] The invention relates to the technical field of fire fighting equipment, in particular to a fire door structure. Background technique [0002] A fire door is a door that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. [0003] As long as the conventional fire doors block the fire through steel or steel-wood doors with flame retardants, they can prevent the fire from expanding within a certain period of time, but in a closed room where important equipment is installed, it is neither possible to transfer the equipment nor ...
