Fire proof door capable of blocking smoke

Abstract

The invention discloses a fire proof door capable of blocking smoke. The door includes a door board, a sealing airbag and a plurality of induction assemblies mounted in an air chamber. A mounting chamber is opened in the door board, evaporation liquid is mounted in the mounting chamber, a piston board is mounted in the mounting chamber in a sealing and sliding mode, and the piston board is locatedabove the evaporation liquid; the sealing airbag is fixedly arranged on the bottom side of the door board, and not in contact with the ground in a non-expansion state, the air chamber is further opened on the door board, the upper end of the air chamber communicates with the mounting chamber, and the lower end of the air chamber communicates with the sealing airbag; and the induction assemblies include wind wheels, a plurality of first magnetic blocks and second magnetic blocks, the wind wheels are mounted in the air chamber in a rotating mode, and the first magnetic blocks are evenly and fixedly mounted on the side edges of the wind wheels. According to the door, when the fire disaster occurs, the sealing airbag expands so as to seal a gap between the door board and the ground, so that the effect of blocking smoke diffusion of the fire proof door can be improved, and the door can facilitate people to evacuate and escape.

Description

technical field [0001] The invention belongs to the technical field of fire doors, in particular to a fire door capable of blocking smoke. Background technique [0002] Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. 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] In order to facilitate the rotation of the door panel, a certain gap is reserved between the door panel and the ground to avoid friction between the door panel and the ground. There will still be some smoke passing through the gap between the door panel and the ground; at the same time, in order to solve this defect, some fire doors will use a complete rectangular door frame, that is, the lower side frame of the door frame is se...

Problems solved by technology

[0003] In order to facilitate the rotation of the door panel, a certain gap is reserved between the door panel and the ground to avoid friction between the door panel and the ground. There will still be some smoke passing through the gap between the door panel and the ground; at the same time, in order to solve this defect, some fire doors will use a complete rectangular door frame, that is, the lower side frame of the door frame is set on the ground. When the fire door is closed, the frame and the door panel The bottom side of the fire door is sealed and in contact, but this design makes it inconvenient for people to pass the fire door every day, and it is easy to stumble; at the same time, after the fire door is closed, it also prevents people from directly observing the situation on the other side of the fire door. Make accurate judgments on the fire on the other side of the fire door, which can easily lead to incorrect evacuation strategies; if people judge that the fire is bigger than the actual fire, it will make people overly nervous, and it is easy to make mistakes in panic If the judged fire intensity is smaller than the actual fire intensity, it is easy to cause people to react slack and delay the best evacuation and escape from the actual situation.
