Description

Barrier-free fireproof door with escape passage

Technical Field

The utility model relates to a fire prevention equipment for escaping technical field especially relates to a barrier-free prevents fire door with passway for escaping.

Background

At present, each public place is provided with a fireproof door or a fireproof rolling door, when a fire disaster occurs, a fire source generating space is separated from people, more time and space are strived for people to escape from a fire scene, people are better helped to escape from the fire scene, and the life safety of people is protected, so that the fireproof door is a very beneficial device, more escape possibilities can be provided for people when the fire disaster occurs, however, at each family of a residential district, no device is provided for helping people to escape from the fire scene, no lock is provided for the general fireproof door in order to facilitate people to escape from the fire scene, isolate the fire scene and rescue, at present, a building in the district has a fireproof channel, but no proper fireproof escape door is provided, when the people get warm in winter, enjoy cool in summer, the electricity consumption is large, and when the fire disaster occurs in the family due to improper electricity consumption, if the people do not pay attention at the moment, or the people fall asleep, general fire burns burglary-resisting door, burglary-resisting door is the metal, the heat conduction is fast, toast the lock very easily and warp, at this moment burglary-resisting door very probably just can't be opened, and the people who sleeps in the room just can only wait for the rescue, only lean on oneself can't leave the scene of a fire almost, even indoor not catching fire, as long as the door lock dies, just can only be stranded indoor, need a flee door now, can prevent burglary at ordinary times, can not lock when meetting the condition of a fire, can also open, can leave the scene of a fire through this flee door, help people strive for more escape possibilities, protect people's life safety.

For example, the disclosure is 2018, 3 and 2, and chinese patent application No. CN201611170968.4 discloses a fire-proof door with a passage, which includes a fire-proof door body and a door frame, wherein the fire-proof door body is mounted on the door frame, the fire-proof door body includes a safety opening disposed at the middle lower part of the fire-proof door body and allowing a human body to pass through, and a passage cover for sealing the safety opening, the safety opening is rectangular, the upper end of the passage cover is hinged to the edge of the safety opening, the lower end of the passage cover is provided with a magnet slot and a fire-fighting opening, a spring and a magnet valve are disposed in the magnet slot, the magnet valve is connected to the magnet slot through the spring, the edge of the safety opening is provided with a groove for matching with the magnet valve to seal the safety opening, an iron block is disposed in the groove, the passage cover is hollow, two cavities are disposed in the passage cover, sodium bicarbonate and, a stop block capable of sealing the liquid outlet is arranged outside the liquid outlet, and the stop block is soft magnet.

Although people escape through the safety opening, the evacuation of people is enhanced, and the problem that people cannot escape due to the loss of action of the fireproof door body is avoided, because two cavities are arranged in the channel cover and are respectively filled with sodium bicarbonate and aluminum sulfate solution, when a fire disaster occurs, the magnetism of the soft magnet for sealing the liquid outlet on the liquid outlet of the cavity disappears due to the high-temperature action, the channel cover inclines, the liquid in the two cavities overflows and mixes to generate a large amount of carbon dioxide gas, when the channel cover is opened, the gas escapes from the fire hole to extinguish the fire and cool the vicinity of the safety opening, the safety of the people is effectively ensured, the special design of the channel cover can ensure that the channel cover is automatically opened when the high temperature occurs, thereby avoiding the situation that the people are scalded when the channel cover is manually opened, and rescue personnel outside the door can enter the room to rescue the room smoothly when the people are smoked down or unconsciously enter the room, however, chemical materials are evacuated on the fire-proof site, if the door is subjected to fire baking, the escape people can be injured by the chemical solution inside the door, a large amount of carbon dioxide gas is released from the door, if the door is locked by the fire baking, people are trapped in a room and the temperature is low, the possibility of suffocation of people waiting for escape is high, people can be scalded by the escape channel in the process that people are drilled, the safe opening is not level with the ground, and more obstacles are brought to people for escape.

Based on this, the utility model designs a barrier-free prevents fire door with passway for escaping to solve above-mentioned problem.
