Technical Field
[0001] The utility model relates to the technical field of fire doors, in particular to a fire door with a fire extinguishing function. Background Art
[0002] Fire doors are specially designed doors whose main function is to delay the spread of fire and high-temperature gases in the event of a fire, buying time for personnel evacuation and fire rescue. They are usually installed in key locations such as evacuation passages, emergency exits, and evacuation stairwells.
[0003] After searching, it was found that the existing fire doors with fire extinguishing function have poor heat resistance and fire resistance when used, and it is difficult to resist the spread of fire for a long time. In addition, the fire situation cannot be seen, and thus a good evacuation environment cannot be provided for refugees.
[0004] Therefore, those skilled in the art provide a fire door with a fire extinguishing function to solve the problems raised in the above background technology. Utility Model Content

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0036] Reference Figure 1-6 The utility model provides an embodiment: a fire door with a fire extinguishing function, comprising a door frame 1 and a door leaf 2, the number of the door leaf 2 is two, the two door leaves 2 are rotated on the inner side of the door frame 1 through a hinge 3, a fire lock 4 is fixedly arranged on one side of one door leaf 2, fireproof glass 8 is fixedly arranged on the two door leaves 2, a cover plate 9 is fixedly arranged on the inner side of the two door leaves 2, a first expansion fireproof sealing strip 10 is fixedly arranged on the inner side of the two door leaves 2 and on one side of the cover plate 9, and a second expansion fireproof sealing strip 10 is fixedly arranged on the inner side of the door frame 1 The expansion fireproof sealing strip 11, through the cooperation among the fireproof glass 8, the cover plate 9, the first expansion fireproof sealing strip 10 and the second expansion fireproof sealing strip 11, can enhance the sealing performance of the fire door while facilitating the observation of the fire situation. The normally open fire door can be automatically closed in the event of a fire through the door closer 14. However, during the automatic closing process, the door leaf 2 is affected by the rotating rod 13 so that the double door leaf 2 is closed in sequence, so that the cover plate 9 does not affect the normal closing of the door leaf 2, thereby improving the practicability of the fire door.
[0037] Smoke sensors 15 are fixedly installed on both sides of the lower end of the door frame 1 and near its front end. Inner cavities 16 are opened on both sides of the upper end of the door frame 1. Water pipes 17 are fixedly installed inside the door frame 1 and in the inner cavity 16. The cooperation between the smoke sensor 15 and the water pipe 17 can mitigate the fire around the fire door, thereby increasing the evacuation time of personnel and the service life of the fire door. The smoke sensor 15 senses the smoke of the fire, so that the water in the water pipe 17 passes through the hose 18 and is sprayed from the sprinkler head 19, thereby mitigating the fire, thereby improving the versatility of the fire door.
[0038] The door frame 1 and the door leaf 2 are both made of steel material. By making the door frame 1 and the door leaf 2 both of them are made of steel material, the fire door can have higher fire resistance performance.
[0039] One of the door leaves 2 has handles 5 rotatably provided at both the front and rear ends and at the lower end of the fire lock 4. The fire door can be manually closed and opened by rotating the handles 5 at both the front and rear ends of the door leaf 2 and at the lower end of the fire lock 4.
[0040] A locking protrusion 6 is fixedly provided on the inner side of one of the door leaves 2, and a locking recess 7 is opened on the inner side of the other door leaf 2. The locking protrusion 6 is stuck in the locking recess 7. By locking the locking protrusion 6 in the locking recess 7, the fire door can be locked to prevent the fire door from being opened under force.
[0041] Door closers 14 are fixedly arranged at the rear ends of the two door leaves 2 and close to their upper ends. The upper ends of the two door closers 14 are fixedly connected to the two sides of the rear end of the door frame 1. By fixing the upper ends of the door closers 14 to the two sides of the rear end of the door frame 1, the door closers 14 can be fixed by the force of the door frame 1 to close the door leaves 2.
[0042] A fixed shell 12 is fixedly provided at the rear end of the lower end of the door frame 1, and a rotating rod 13 is rotatably provided on one side of the fixed shell 12. By rotating the rotating rod 13 on one side of the fixed shell 12, the door leaf 2 can be closed sequentially during the closing process.
[0043] The lower ends of the two water pipes 17 are fixedly connected to hoses 18, and the lower ends of the two hoses 18 pass through the smoke sensor 15 and are fixedly connected to the sprinkler heads 19. By passing the lower ends of the hoses 18 through the smoke sensor 15 and being fixedly connected to the sprinkler heads 19, the fire around the fire door can be sprayed, thereby slowing down the spread of the fire and buying time for personnel evacuation and fire rescue.
[0044] Working principle: When the fire door with fire extinguishing function is in use, first, when there is no fire, the fire door is normally open. When a fire occurs, the door closer 14 will automatically close the fire door. At the same time, the door frame 1 and the door leaf 2 are both made of steel material, which has high fire resistance. At the same time, during the closing process of the fire door, the door leaf 2 is affected by the rotating rod 13 so that the double door leaf 2 is closed in sequence, so that the cover plate 9 does not affect the normal closing of the door leaf 2. At the same time, the cover plate 9, the first expansion fireproof sealing strip 10 and the second expansion fireproof sealing strip 11 can further enhance the sealing performance of the fire door. Then the smoke sensor 15 senses the smoke of the fire, so that the water in the water pipe 17 passes through the hose 18 and is sprayed from the sprinkler head 19, thereby reducing the fire. The fire situation can be observed through the fireproof glass 8, which buys time for personnel evacuation and fire rescue, thereby improving the practicality and versatility of the fire door.
[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
