Technical Field
[0001] The utility model belongs to the technical field of fireproof doors, and in particular relates to a fireproof door which is easy to disassemble. Background Art
[0002] Fire doors are a type of door, so their function is like that of ordinary doors, with the function of separation and protection. However, fire doors are different from other doors in that they have the function of preventing the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel. Fire doors can be classified according to their materials: wooden fire doors, steel fire doors, steel-wood fire doors and fire doors made of other materials. The fire doors we commonly use are wooden fire doors and steel fire doors. Fire doors have certain shortcomings when used: when a fire occurs and the door lock of the fire door is damaged, the fire door will prevent people from escaping, and existing fire doors are generally installed as a whole, and the fire door and door frame are mostly connected by bolts and hinges, which are not easy to disassemble. In an emergency, when the door lock is damaged, it will lead to inability to escape, posing a huge safety hazard. It is not convenient to disassemble. Therefore, when the above situation occurs, it will greatly reduce the chance of people being rescued, posing a huge safety hazard. After searching, it was found that the application number "202320592580.2" disclosed "a fire door that is easy to disassemble Fire door", which records "including a door frame and a fire door body installed in the door frame, a plurality of hinged components distributed up and down are installed between the edge of one side of the fire door body and the door frame, a C-shaped part is fixed on one side of the fire door body near the position of the hinged component, two extension blocks are fixed on the C-shaped part, the two extension blocks are plugged with the same pin shaft, and a limit block connected to the pin shaft is fixed on the top side of the hinged component". The above-mentioned fire door can be removed by quickly disassembling the hinged component when in use, but the above-mentioned fire door still has certain shortcomings when in use: since the hinged component is installed on one side of the fire door, when people are on the other side of the fire door, they cannot disassemble the fire door. When there is no one outside the door to help disassemble the fire door, people cannot disassemble it, and there are still certain safety hazards. Based on this, we propose that it is very necessary to have a fire door that can be disassembled on both sides of the door. Utility Model Content

[0037] In this embodiment, the position of the limiting hole 56 corresponds to the position of the opening, and the size of the limiting hole 56 matches the size of the limiting protrusion 58 .
[0038] Specifically, the fire door can be disassembled quickly and conveniently in this manner.
[0039] In this embodiment, one end of the limiting protrusion 58 located in the adjusting groove 511 is in a smooth round head shape.
[0040] Specifically, in this way, the wedge-shaped surface 512 can squeeze the limiting protrusion 58 so that the limiting protrusion 58 can be quickly separated from the limiting hole 56, thereby improving the disassembly efficiency of the fire door.
[0041] Working principle: When a fire occurs and the door lock is damaged, the personnel only need to remove the rotating block 13 and insert the fixing block 12 into the first fixing groove 11, and then rotate the rotating block 13 to disengage the fixing screw 10 from the first screw hole 8 and the second screw hole 9. Then the personnel pulls the handle 55 downward, so that the I-shaped member 51 squeezes the first spring 53 downward and the insertion rod 54 disengages from the insertion hole 6. During the descent of the I-shaped member 51, the adjusting rod 510 will move downward to squeeze the wedge surface 512 to squeeze the limiting protrusion 58, so that the limiting protrusion 58 disengages from the limiting hole 56. In this way, the auxiliary door frame 2 is disengaged from the main door frame 1, which facilitates the escape of personnel. The fire door can be disassembled by personnel on both sides of the fire door, thereby effectively improving the escape rate of personnel and reducing the risk of personnel being blocked by the fire door and unable to escape in the event of a fire.
