Energy-saving broken bridge aluminum alloy door

The utility model discloses an energy-saving broken bridge aluminum alloy door which comprises an outer frame, a door frame, supporting columns and dustproof rubber strips, the supporting columns canbe connected with the outer frame and the door frame, one side of the door frame is rotatably connected with a glass door A through hinges, and the other side of the door frame is rotatably connectedwith a glass door B through hinges. According to the sound-proof glass door, the sound-proof damping film A and the sound-proof damping film B are adopted, the sound-proof damping film can absorb sound waves transmitted from the outside and prevent the sound waves from penetrating through the glass door, the double-layer sound-proof damping film can better absorb the absorption rate of the sound waves enhanced by the sound waves, and meanwhile the vacuum cavity is formed in the glass door. The sound wave is not provided with a transmission medium in a vacuum environment, so that the sound wavecannot pass through the va
