[0043] Preferably, when the door leaf 4 and the door frame 1 are closed, the fourth sealing strip 74 and the fourth sealing strip pressing surface 34 are pressed and sealed, and when the door leaf 4 and the door frame 1 are closed, the second sealing strip 72 and the third sealing strip 73 are pressed and sealed, and the deformation part 76 and the support part 77 are made of ethylene propylene diene monomer. The deformation part 76 is pressed and deformed by fitting with the sealing surface, and the support part 77 provides support for the deformation part 76 to prevent the deformation part 76 from generating gaps on the fitting surface due to extrusion deformation and damaging the sealing structure.

[0044] Preferably, when the door leaf 4 is closed with the door frame 1, the sealed space enclosed by the first sealing strip 71 and the first sealing strip pressing surface 42 and the second sealing strip 72 and the third sealing strip 73 is the first sealed cavity 81, and the sealed space enclosed by the second sealing strip 72 and the third sealing strip 73 is the second sealed cavity 82. The first sealed cavity 81 and the second sealed cavity 82 form two enclosed spaces, which significantly reduce the transmission of noise and improve the sound insulation effect in the room. The double-layer sealed cavity effectively seals the gap between the door leaf and the door frame to prevent dust from entering the room. Especially under severe weather conditions, the double-layer sealing structure can effectively block external dust and maintain indoor cleanliness and air quality.

[0045] The utility model realizes a double-layer sealing structure through the technical scheme of tight sealing between the first sealing strip 71 and the door leaf 4, tight sealing between the second sealing strip 72 and the third sealing strip 73, and tight sealing between the fourth sealing strip 74 and the door frame 1, thereby solving the problem of unsatisfactory sealing effect of the existing entrance door.
