[0017] The present invention has the following beneficial effects:

[0018] (1)In a fireproof aluminum alloy door and window with a sealing structure according to the present invention, when the aluminum alloy door and window frame is exposed to high-temperature fire roasting, the phase-change material plate in the U-shaped cavity can undergo a phase change under high-temperature conditions, absorb heat and release a large amount of water vapor, thereby playing a role in heat insulation and flame retardancy, effectively improving the heat resistance of the aluminum alloy door and window frame. When the water vapor in the U-shaped cavity reaches a certain threshold, the high-strength water vapor will push two rectangular pistons closer to each other, and the rectangular pistons will push the nitrogen gas in the U-shaped cavity to squeeze the baffle. During the continuous movement of the rectangular pistons, the nitrogen gas will push the baffle open. At this time, the nitrogen gas in the U-shaped cavity will be ejected from the U-shaped cavity to the outside of the aluminum alloy door and window frame. The nitrogen gas will form an inert environment and inhibit the oxygen supply reaction during combustion, thereby extinguishing the flame;

[0019] (2)In a fireproof aluminum alloy door and window with a sealing structure according to the present invention, under the push of water vapor, it will drive the limiting block one in the limiting groove one to move upward. The limiting block one drives the U-shaped rod to move upward, and the U-shaped rod drives several elastic members to move upward. During the movement of the elastic members, they will contact the bell, and each elastic member will make a sound when it contacts the bell, thereby reminding the residents who are sleeping soundly at night to escape, playing an alarm role, making a reminder in the first time, and effectively improving the escape probability of the residents;

[0020] (3)In a fireproof aluminum alloy door and window with a sealing structure according to the present invention, under the action of water vapor, it will also drive the limiting block two in the limiting groove two to move upward. The limiting block two drives the fixed push rod to move upward, and the fixed push rod will enter the transmission groove and push the U-shaped limiting rod to move upward. Under the action of the gear, the gear drives the rotating rod to rotate, the rotating rod drives the connecting rod one to rotate, the connecting rod one drives the connecting rod two to move, and the connecting rod two drives the limiting slide rod two and the limiting slide rod one to move, thereby driving the fireproof board to move and seal the rectangular through groove, preventing the burning smoke from entering the room and causing the danger of difficulty in breathing and lack of oxygen for the residents;

[0021] (4)In a fireproof aluminum alloy door and window with a sealing structure according to the present invention, when a fire is detected, the two aluminum alloy doors and windows are immediately closed. When the two aluminum alloy doors and windows intersect, the grooved L-shaped plate will be stuck into the L-shaped fixing block, and the elastic limiting block will pass through the two semi-circular blocks. Under the action of several springs, the sealing plate will be firmly attached to the two semi-circular blocks to prevent the burning smoke from floating into the room. Then, rotate the turntable, the turntable drives the threaded rod to rotate, the threaded rod drives the rectangular plate in the rectangular groove to move and enter the trapezoidal groove. Under the action of the trapezoidal groove slope, the two aluminum alloy doors and windows will move away from each other, making the two aluminum alloy doors and windows close to the bridge-shaped ring groove, further improving the sealing performance.

[0051] By providing the ventilation mechanism 08, ventilation can be carried out through the rectangular through groove 36 in daily life to ensure good indoor ventilation. The dust-proof plate 37 can prevent dust from entering the room.

[0052] As Figure 8 shown in the figure, a closing mechanism 09 is provided on the two mounting blocks 38. The closing mechanism 09 includes Y-shaped limiting grooves 39 respectively opened on the two mounting blocks 38. In front of the dust-proof plate 37, a first limiting slide rod 40 and a second limiting slide rod 41 are provided.

When the water vapor in the C-shaped cavity 2 reaches a certain threshold, the high-strength water vapor will push the two rectangular pistons 5 closer to each other. The rectangular pistons 5 will push the nitrogen gas in the C-shaped cavity 2 to squeeze the baffle 8. During the continuous movement of the rectangular pistons 5, the nitrogen gas will push the baffle 8 open. At this time, the nitrogen gas in the C-shaped cavity 2 will be ejected from the C-shaped cavity 2 to the outside of the aluminum alloy door and window frame 1. The nitrogen gas will form an inert environment and inhibit the oxygen supply reaction during combustion, thereby extinguishing the flame. Driven by the water vapor, the first limiting block 25 in the first limiting groove 24 will move upward. The first limiting block 25 drives the C-shaped rod 27 to move upward. The C-shaped rod 27 drives a plurality of elastic members 28 to move upward. During the movement of the elastic members 28, they will contact the bell 29. Each elastic member 28 will make a sound when it contacts the bell 29, thereby reminding the residents sleeping at night to escape and playing an alarm role, making a reminder in the first time.

[0057] Under the action of water vapor, the second limiting block 31 in the second limiting groove 30 will also move upward. The second limiting block 31 drives the fixed push rod to move upward. The fixed push rod will enter the transmission groove 33 and push the C-shaped limiting rod 34 to move upward. Under the action of the gear 47, the gear 47 drives the rotating rod 44 to rotate. The rotating rod 44 drives the first connecting rod 45 to rotate. The first connecting rod 45 drives the second connecting rod 46 to move. The second connecting rod 46 drives the second limiting slide rod 41 and the first limiting slide rod 40 to move, thereby driving the fireproof board 43 to move and seal the rectangular through groove 36, preventing the burning smoke from entering the room and causing the danger of difficulty in breathing and lack of oxygen for residents. When a fire is detected, immediately close the two aluminum alloy doors and windows 10. When the two aluminum alloy doors and windows 10 intersect, the grooved L-shaped plate 13 will be stuck into the L-shaped fixing block 12, and the elastic limiting block 18 will pass through the two semi-circular blocks 14. Under the action of several springs 17, the sealing plate 16 will be firmly pressed against the two semi-circular blocks 14 to prevent the burning smoke from floating into the room. Then rotate the turntable 23. The turntable 23 drives the threaded rod 22 to rotate. The threaded rod 22 drives the rectangular plate 21 in the rectangular groove 20 to move and enter the trapezoidal groove 19. Under the action of the inclined surface of the trapezoidal groove 19, the two aluminum alloy doors and windows 10 will move away from each other, so that the two aluminum alloy doors and windows 10 are closely attached to the bridge-shaped ring groove 9.
