A Chinese patent document with publication number CN209586149U discloses a soundproof and fireproof door, which includes a door frame and a door leaf, with one adjacent side of the door frame and door leaf hinged together. The door frame contains a hollow frame with an L-shaped cross-section, and its outer surface has an annular plate for connecting to the cabin bulkhead. The inner perimeter of the annular plate is integrally formed with the outer surface of the door frame. The door leaf contains a hollow plate, the size of which is adapted to the area enclosed by the inner side of the door frame. Both the hollow frame and the hollow plate are made of aluminum alloy and filled with ceramic wool. Its distinguishing feature is that the vertical and horizontal sections of the hollow frame, as well as the inner side of the ends of the vertical sections, are all composited with stainless steel plates. The annular plate contains two layers of plates, the outer edges of which are integrally formed. The outer surface of the vertical section of the hollow frame corresponding to the two layers of plates has a circumferential opening, and the inner perimeter of the two layers of plates is integrally formed with the sides of the circumferential opening. A stainless steel plate is placed between the two layers of panels, extending inward to form an integral unit with the stainless steel plate inside the vertical section of the hollow frame. The ceramic wool inside the door leaf has fireproof panels on both sides. However, the sealing between the door leaf and the door frame in the above solutions is insufficient, resulting in inadequate protection during a fire.

The door leaf 2 is rotatably installed on the door frame 1 via a hinge 4, and a lock body 6 is fixedly installed on the door leaf 2. A primary internal corner groove 7 is formed on the inner side wall of the door frame 1, and the primary internal corner groove 7 is arranged around the door frame 1. A primary sealing groove 11 is formed on the transverse side wall of the primary internal corner groove 7, and a secondary sealing groove 12 is formed on the longitudinal side wall of the primary internal corner groove 7. The sealing structure 3 includes a primary sealing body 13 and a secondary sealing body 14. The primary sealing body 13 is embedded in the primary sealing groove 11, and the secondary sealing body 14 is embedded in the... In the secondary sealing groove 12, both the primary sealing body 13 and the secondary sealing body 14 are elastic. When the door leaf 2 is closed, both the primary sealing body 13 and the secondary sealing body 14 are in a compressed state. By setting up a shipboard integrated fireproof and smoke-proof sealing door composed of a door frame 1, a door leaf 2 and a sealing structure 3, and setting the door frame 1 to be composed of an outer fireproof layer 15 and an inner heat insulation layer 16, and setting the door leaf 2 to be composed of an outer fireproof layer 8, a middle heat insulation layer 9 and an inner fireproof layer 10, and setting the middle heat insulation layer 9 to be composed of a protective frame 17, an outer heat insulation layer 18, a sound insulation board 19 and an inner heat insulation layer 20, the heat insulation and fireproof effect of the door leaf 2 can be greatly improved while controlling the thickness of the door leaf 2.
[0019] The door frame 1 consists of an outer fireproof layer 15 and an inner heat insulation layer 16. The outer fireproof layer 15 is made of steel profiles, and the inner heat insulation layer 16 is made of asbestos profiles. The door leaf 2 includes an outer fireproof layer 8, a middle heat insulation layer 9, and an inner fireproof layer 10.

A secondary internal corner groove 25 is provided at the corner position of the primary internal corner groove 7 near the inner wall of the door frame 1. When the door leaf 2 is closed, the inner side of the outer fireproof layer 8 abuts against the outer side of the door frame 1, the side of the middle heat insulation layer 9 abuts against the longitudinal side wall of the primary internal corner groove 7, the inner side of the middle heat insulation layer 9 abuts against the transverse side wall of the primary internal corner groove 7, the side wall of the inner fireproof layer 10 abuts against the longitudinal side wall of the secondary internal corner groove 25, and the inner side of the inner fireproof layer 10 abuts against the transverse side wall of the secondary internal corner groove 25. The arrangement of the primary internal corner groove 7 and the secondary internal corner groove 25 allows a stepped engagement between the door frame 1 and the door leaf 2, thereby further improving the sealing effect between the door frame 1 and the door leaf 2.
[0023] Example 3: Please refer to Figure 1-12 Based on Embodiment 2, the primary sealing body 13 includes a primary airbag body 23 and a sealing rubber frame 24. Both the primary airbag body 23 and the sealing rubber frame 24 are disposed in the primary sealing groove 11.

The primary sealing groove 11 and the secondary sealing groove 12 are connected by a connecting groove 22. The connecting groove 22 is L-shaped and is evenly arranged around the primary sealing groove 11. The secondary sealing body 14 and the primary airbag body 23 are connected by a connecting air pipe 29.
[0024] The inner cavity of the secondary sealing body 14 is provided with a primary connecting plate 26, a secondary connecting plate 27, and a reset elastic member 28 in both the transverse and longitudinal directions.

When the secondary sealing body 14 is in the reset state, the reset elastic member 28 is also in the reset state. At this time, the reset elastic member 28 completely pulls the outer side of the secondary sealing body 14 into the secondary sealing groove 12.
[0025] During the closing process, when door 2 contacts the sealing rubber frame 24, the middle heat insulation layer 9 has already covered the end face of the secondary sealing groove 12, and the thickness of the inner part of the secondary sealing body 14 is three times the thickness of the outer part. By setting the primary sealing body 13 to be composed of the primary airbag body 23 and the sealing rubber frame 24, and connecting the secondary sealing body 14 and the primary airbag body 23 of the airbag structure through the connecting air pipe 29, and ensuring that the primary airbag body 23 and the secondary sealing body 14 are in the reset state, the sealing rubber frame 24 can protrude from the primary sealing groove 11. On the outside, when the door leaf 2 is closed, the excess gas in the primary airbag 23 will be squeezed into the secondary sealing body 14 through the connecting air pipe 29, so that the secondary sealing body 14 can better contact and seal with the door leaf 2, and can effectively avoid the secondary sealing body 14 from interfering with the opening and closing of the door leaf 2. The primary sealing body 13 can not only seal the door frame 1 and the door leaf 2, but also buffer the door leaf 2 when it is closed, thus effectively protecting the door frame 1 and the door leaf 2, thereby realizing the multi-functionality of the primary sealing body 13.
