Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and in particular to a novel airtight sound insulation protective door. Background Art

[0002] A protective door refers to a door made of related equipment in situations where a specific area needs to be protected during production or use. Protective doors are generally set up to prevent gas, liquid, dust leakage or to prevent toxic, flammable, explosive, radioactive and other harmful substances from causing harm to the environment and personnel. The quality of the protective door is determined by its air tightness and sound insulation performance. Most of the existing protective doors are steel door panels. The protective doors made of steel door panels have good impact resistance and sturdiness, but the sound insulation performance of the protective doors made of steel door panels is poorer than that of wooden doors, and the air tightness is not very good, which needs further improvement.

DETAILED DESCRIPTION

[0016] The utility model is now described in further detail with reference to the accompanying drawings.

[0017] In the embodiments, it should be understood that the terms "middle", "upper", "lower", "top", "bottom", "right", "left", "above", "below", "back", "front", "middle", "outside", "inside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the embodiments.

[0018] like Figure 1 to Figure 2 As shown, a novel airtight soundproof protective door comprises a door frame 1 and a door panel 2, wherein the door frame 1 is movably connected to the door panel 2 through a hinge, a rectangular baffle 3 is fixed to the inner circle of the door frame 1, two sealing baffles 4 are arranged on the side of the baffle 3 close to the door panel 2, and the shape of the sealing baffles 4 is also rectangular, and a spacing sealing groove 5 is formed between the two sealing baffles 4, and a steel ring strip 7 is arranged at the bottom of the sealing groove 5, and the steel ring strip 7 is also rectangular, and the door panel 2 comprises a steel inner panel 202 and a steel outer panel 201, and door handles are arranged on the steel inner panel 202 and the steel outer panel 201, and a damping sound insulation board 204, a sound insulation cotton layer 205, and a polycrystalline sand sound absorbing board 203 are arranged in sequence between the steel inner panel 202 and the steel outer panel 201, and a magnetic sealing strip 6 is arranged on the outer surface of the steel outer panel 201, and the magnetic sealing strip 6 is also rectangular.
