[0022] 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.
[0023] See also Figure 1-5The utility model provides a technical solution: a fireproof door with good sealing performance, comprising a door frame 1, a door 2 is arranged inside the door frame 1, the door 2 is connected to the door frame 1 by a hinge, the door 2 and the door frame 1 are filled with perlite board, bosses 3 are arranged at the upper and lower ends of the inner side of the door frame 1 and at the front end of the door 2, a card slot 4 is opened inside the boss 3, side card slots 5 are opened on the left and right sides of the door frame 1 and at the front end of the boss 3, protrusions 6 are arranged on the upper and lower ends and the left and right front ends of the front surface of the door 2, the protrusions 6 are inserted and connected with the card slots 4 and the side card slots 5, a frame 7 is arranged at the front end of the right surface of the left door 2, and a frame groove 8 is opened at the left end of the front surface of the right door 2, and the outer surface of the protrusion 6, the card slot 4, the inside of the side card slot 5, the front surface of the frame 7 and the rear surface of the frame groove 8 are all covered with chloroprene rubber.
[0024] When working, after the door 2 is closed, the protrusions 6 at the upper and lower ends of the front surface of the door 2 and the front ends of the left and right sides will be stuck into the inside of the card slot 4 and the side card slot 5, and the frame 7 will overlap with the frame slot 8. At this time, the neoprene on the outer surface of the protrusion 6, the card slot 4, the inside of the side card slot 5, the front surface of the frame 7 and the rear surface of the frame slot 8 are in contact with each other. When a fire occurs, the door 2 will block the fire outside the door 2, and the perlite board filled inside the door 2 and the door frame 1 can not only prevent the spread of fire, but also block a part of the temperature from being transmitted to the room through the door 2. The neoprene can improve the airtightness of the connection, so that smoke is not easy to enter the room through the gap between the door 2 and the frame 1. The neoprene has high tensile strength, excellent heat resistance, light resistance and aging resistance, which can improve the service life and ensure the normal operation of the neoprene at a certain temperature. When there is no fire, the fire door with good sealing performance can be used normally like an ordinary door.
[0025] See also Figure 1-3 The utility model provides a technical solution: a fireproof door with good sealing performance, wherein door closers 21 are arranged at both left and right ends of the rear surfaces of the door frame 1 and the door 2.
[0026] During operation, the door closers 21 at the left and right ends of the door frame 1 and the rear surface of the door 2 can play a buffering role. At the same time, under the action of the internal hydraulic pressure of the door closer 21, the door 2 will automatically close, and when a fire occurs and no one finds it, it will also be in a closed state to prevent the fire from spreading.
[0027] See also Figure 1-3 The utility model provides a technical solution: a fireproof door with good sealing performance, wherein a smoke alarm 22 is arranged on the upper end of the front surface of the door frame 1.
[0028] During operation, when a fire occurs and smoke spreads to the smoke alarm 22, a buzzer inside the smoke alarm 22 will be activated to emit a noise to remind people of the fire. At the same time, the smoke alarm 22 can play a guiding role, reminding people of the location of the fire door with good sealing performance.
[0029] See also Figure 1-4 The utility model provides a technical solution: a fireproof door with good sealing performance, wherein a supporting frame 23 is arranged inside the door 2.
[0030] During operation, the support frame 23 disposed inside the door 2 can improve the overall strength of the door 2 and evenly distribute the overall stress of the door 2 to prevent the welding parts of the door 2 from separating due to excessive local stress caused by excessive temperature.
[0031] See also Figure 1-3 The utility model provides a technical solution: a fireproof door with good sealing performance, a water pipe 24 is arranged inside the boss 3 and at the front end of the slot 4, the water pipe 24 extends to the left and right sides of the door frame 1, and a fire sprinkler head 25 is arranged on the lower surface of the boss 3, and the upper end of the fire sprinkler head 25 is connected to the water pipe 24.
[0032] During operation, the water pipe 24 is connected to the tap water pipeline. When the temperature is too high, the thermal glass inside the fire sprinkler head 25 will be melted, and then the plug will be flushed open by the water flow. The water enters the fire sprinkler head 25 through the water pipe 24 and then sprays out. While preventing the fire from spreading, it cools down the door 2 and prevents the internal lock core from melting through heat conduction. At the same time, it prevents the temperature of the door handle from being too high, so that the escapee's hands will be scalded by the door handle when opening the door.
[0033] See also Figure 1-3 The utility model provides a technical solution: a fireproof door with good sealing performance, wherein the door frame 1 and the door 2 are made of cast iron.
[0034] When working, the door frame 1 and the door 2 are made of cast iron, which has the effects of high hardness and high temperature resistance. While extending the service life, it can prevent the door frame 1 and the door 2 from being damaged by very high temperatures.
[0035] To sum up, when the fireproof door with good sealing performance is closed, the protrusions 6 at the upper and lower ends of the front surface of the door 2 and the front ends of the left and right sides will be stuck in the slots 4 and the side slots 5, and the frame 7 and the frame slot 8 will overlap. When a fire occurs, the door 2 will block the fire outside, and the smoke will be blocked by the neoprene covering the connection between the protrusion 6 slot 4 and the side slot 5, preventing the smoke from entering the room.
