[0014] A further technical solution: A connecting groove is provided on the rotating plate, and a connecting rod that is fixedly installed on the second rack is slidably installed in the connecting groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. After the door is closed, the first sealing plate is in close contact with the fixed baffle through the first fireproof sealing ring, and the second sealing plate is in close contact with the door through the second fireproof sealing ring. The first and second sealing plates are connected by a fireproof sealing strip, thereby achieving real-time sealing of the gap between the fixed baffle and the door. This changes the sealing position of the gap between the closed door and the door frame, ensuring that both the first and second fireproof sealing rings are pressed vertically onto the plane. This avoids the door exerting oblique shearing force on the first and second fireproof sealing rings when closing, reducing the probability of bending deformation of the first and second fireproof sealing rings. At the same time, the first and second fireproof sealing rings will not rub against the door or the fixed baffle, reducing wear and further improving the sealing effect. After the door is closed, it can be fully sealed and protected, preventing humid air, moisture, smoke, and heat from entering the vault through the gap between the door and the door frame, thus improving the protective effect of the door.

[0017] 2. The two sets of elastic elements are compressed by the movement of the power frame, thereby applying pressure to the first and second sealing plates. The pressure can be applied vertically to the first and second fireproof sealing rings, avoiding unnecessary bending deformation of the first and second fireproof sealing rings. At the same time, the pressure on the first and second sealing plates can be adjusted by the distance the moving frame moves. Thus, even when the sealing surfaces of the first and second fireproof sealing rings wear down, sufficient pressure can always be applied to the first and second fireproof sealing rings to ensure their sealing effect.

[0018] 3. When the first and second sealing plates move toward the door, they simultaneously drive the piston plate to move inside the air cylinder. The piston plate pushes the air inside the air cylinder toward the area where the second fireproof sealing ring is about to contact the door. This allows the high-speed airflow to clean the area where the second fireproof sealing ring will contact the door as it moves toward but does not yet contact the door. Furthermore, when the second fireproof sealing ring approaches the door, the high-speed airflow will also clean its surface, ensuring the cleanliness of the area where the door and the second fireproof sealing ring contact, improving the sealing effect of the second fireproof sealing ring, and further enhancing the protective effect of the door.

[0019] 4. When the temperature inside the third chamber is high, the power assembly will drive the piston plate to reciprocate within the air cylinder while pressing the first and second sealing plates. This allows air from inside the vault to enter the air cylinder and be exhausted through the second and first chambers, blowing towards the contact point between the second fireproof sealing ring and the door. As the air flows from the second chamber into the first chamber, it carries away the heat from the fireproof sealing strip. Simultaneously, as the air blows from the first chamber towards the second fireproof sealing ring, it carries away the heat from the second sealing plate and the second fireproof sealing ring, thereby reducing the temperature of the second fireproof sealing ring. This achieves continuous cooling of the fireproof sealing strip and the second fireproof sealing ring, preventing them from remaining at high temperatures for extended periods. This reduces the aging rate of the fireproof sealing strip and the second fireproof sealing ring, improves their sealing effect and service life, and further enhances the protective effect of the door.

When the door body 2 is opened, the telescopic piece 14 is first reset, at this time the second fireproof sealing ring 11 is separated from the contact with the door body 2, and then the door body 2 is opened, so as to avoid the contact between the door body 2 and the second fireproof sealing ring 11 when the door body 2 is closed and opened, which causes the deformation of the second fireproof sealing ring 11, further improves the tightness of the contact between the second fireproof sealing ring 11 and the door body 2 in subsequent use, and further improves the sealing effect.
