Vacuum sound-insulation glass door

Abstract

The invention relates to a vacuum sound-insulation glass door. The vacuum sound-insulation glass door comprises a glass piece and a frame. The frame comprises a fixed frame and a fixed rotary shaft, the fixed rotary shaft is sleeved with an isolation sash, the outside of the isolation sash is coaxially sleeved with a rotary cylinder, and the rotary cylinder is connected with the isolation sash through a one-way bearing. A glass clamping piece is arranged on the outer cylindrical wall of the rotary cylinder. A one-way air guiding channel is further arranged between the rotary cylinder and the glass clamping piece. The vacuum sound-insulation glass door further comprises an air exhausting cylinder. A circular-arc-shaped piston rod is further arranged in the air exhausting cylinder and can perform airtight reciprocating motion in the air exhausting cylinder. One end of the piston rod is fixed to the glass clamping piece, and a one-way air valve is arranged at the other end and only permits air to be discharged out of the air exhausting cylinder. The vacuum sound-insulation glass door is novel in structure and good in air tightness, can keep the vacuum degree between sound-insulation glass for a long time and improve heat-preservation and sound-insulation effects.

Description

technical field [0001] The invention relates to a door body of an interior building, in particular to a soundproof glass door. Background technique [0002] Vacuum glass is to seal the surroundings of two sheets of flat glass, evacuate the gap and seal the exhaust holes, so that the air between the two layers of glass is thin, and the heat transfer of the gas is negligible; at the same time, the vacuum layer can effectively block the sound. Conduction plays the role of sound insulation; however, the traditional sound-proof glass is made with low precision. After a period of use, the airtightness between the glasses decreases, the vacuum layer enters the air, and the heat preservation and noise reduction functions of the sound-proof glass will be greatly reduced; at the same time , There is a large gap between the frames of the fixed sound-proof glass, and the sound and heat are transmitted through the gap between the frames. This structure greatly affects the effect betwee...

Problems solved by technology

[0002] Vacuum glass is to seal the surroundings of two pieces of flat glass, evacuate the gap and seal the vent holes, so that the air between the two layers of glass is thin, and the heat transfer of the gas is negligible; at the same time, the vacuum layer can effectively block the sound. Conduction plays the role of sound insulation; however, the production precision of traditional sound-proof glass is low. After a period of use, the airtightness between the glasses decreases, the vacuum layer enters the air, and the heat preservation and noise reduction functions of the sound-proof glass will be greatly reduced; at the same time , There is a large gap between the frames of the fixed sound-proof glass, and the sound and heat are transmitted through the gap between the frames. This structure greatly affects the effect between the sound-proof glass wall and the door; making the vacuum glass unable to reflect its own advantages
