[0002] In the shipbuilding industry, it's well known that to eliminate the significant noise generated by equipment during navigation, most ship hatches utilize soundproof doors with sound-isolating properties. These doors consist of a door frame and a door leaf, hinged together at one of the adjacent vertical edges. The door leaf comprises an inner and outer metal sheet, with the space between the inner and outer metal sheets filled with sound-absorbing materials such as rock wool. While this type of soundproof door meets sound insulation requirements, its lack of ventilation limits its use in unoccupied cabins where sound insulation is required but ventilation is not. It cannot be used in occupied cabins, such as meeting rooms and medical rooms, where both sound insulation and ventilation are required. Utility Model Content

[0030] The lower door frame 14 is a hollow profile with a rectangular cross-section. Sound insulation cotton is also provided in the hollow cavity of the lower door frame 14. A pair of inner sides of the lower door frame 14 have a third sealing groove formed by bending outward and protruding outward. A third sealing strip 11 is provided in the third sealing groove.

[0031] A door leaf 30 is provided in the door frame 10 , and adjacent vertical sides of the door frame 10 and the door leaf 30 are hinged together by a set of hinges 20 ; in this embodiment, the hinges 20 are preferably silent hinges;

[0032] like Figure 4 As shown, the door leaf 30 includes a frame, which includes an upper frame 34 and a lower frame 35. Figure 9-10 As shown, an outer door panel 36 is provided on the outer side of the frame. The outer door panel 36 has a first opening 37 corresponding to the upper frame 34 and a second opening 38 corresponding to the lower frame 35. An inner door panel 39 is provided on the inner side of the frame. The inner door panel 39 also has a first opening 37 corresponding to the upper frame 34 and a second opening 38 corresponding to the lower frame 35.

[0033] The frame between the outer door panel 36 and the inner door panel 39 is provided with rock wool, which can be pre-laid on the outer door panel 36 and the inner door panel 39;

[0034] like Figure 5 As shown, a porous mesh plate 32 is further provided on the skeleton between the rock wool corresponding to the upper frame 34, and a first opening 37 is also correspondingly provided on the porous mesh plate 32;

[0035] A transparent window 40 is provided on the frame corresponding to the position of the first opening 37, and the window 40 is preferably made of vacuum fireproof and soundproof glass;
