[0024] Reference Figure 1-6 This utility model provides a steel soundproof and heat-insulating door, which inherently possesses certain heat insulation, heat preservation, and fireproofing functions. This technical solution focuses on explaining its improved safety structure:

[0025] The soundproof and heat-insulating door of this technical solution mainly includes a steel outer door panel 1, and a steel inner door panel 9 fixedly connected to the outer surface of the steel outer door panel 1. The inner door panel 9 has a protective device inside, which includes a protective plate 8, a rotating handle 19, and a protective plate 12. A push rod 17 is fixedly connected to the outer surface of the protective plate 8, and the push rod 17 is slidably connected to the inner surface of the steel outer door panel 1. A push rod 23 is also slidably connected to the inner surface of the steel outer door panel 1. A linkage rod 18 is fixedly connected to the outer surface of the push rod 17, and a rack 20 is fixedly connected to the outer surface of the linkage rod 18. A push rod 23 is fixedly connected to the outer surface of the protective plate 12, and a linkage rod 22 is fixedly connected to the outer surface of the push rod 23. A rack 21 is fixedly connected to the outer surface of the linkage rod 22. The output end of the rotating handle 19 is connected to the rack 20 and rack 21 respectively via gears.

[0026] The steel inner door panel 9 has slots on both the left and right sides. Protective plate 1 8 is movably connected to the left slot, and protective plate 2 12 is movably connected to the right slot. The interior of the steel inner door panel 9 is equipped with a thermal insulation and soundproofing board 14. A heavy-duty hinge 10 is fixedly connected to the right surface of the steel inner door panel 9. A right-side upright 3 is fixedly connected to one side of the heavy-duty hinge 10. An upper crossbeam 4 is fixedly connected to the upper end of the right-side upright 3, and a left-side upright 6 is fixedly connected to one end of the upper crossbeam 4. A latch plate 15 is fixedly connected to the outer surface of the left-side upright 6.
