Environment-friendly sound-insulation aluminum alloy door and window

Abstract

The invention discloses an environment-friendly sound-insulation aluminum alloy door and window, and belongs to the field of aluminum alloy doors and windows. According to the scheme, when the decibel of external noise is too large, a rotating rod is rotated, so that a first rotating shaft connected with a universal joint drives a second rotating shaft to rotate, two winding boxes at the outer end of a transmission shaft core wind a lifting rope at the moment, a sound insulation plate base between two pieces of sound insulation glass is changed in form and tends to be in a vertical state, a sound insulation layer is formed between the interiors of the two pieces of sound insulation glass and attached to the inner walls of the two pieces of sound insulation glass, and the situation of noise infiltration is effectively avoided; and meanwhile, sound insulation cotton in an inner cavity of the sound insulation plate base weakens and attenuates the noise, so that the noise is not prone to being transmitted into a room at too large decibel, an interlayer of a double-layer and multi-layer structure is formed, and the weakening and attenuating effects on sound transmission are further enhanced.

Description

technical field [0001] The invention relates to the field of aluminum alloy doors and windows, and more specifically relates to an environment-friendly and sound-insulating aluminum alloy door and window. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. They are called aluminum alloy doors and windows, referred to as aluminum doors and windows. Composite doors and windows, aluminum alloy has the characteristics of low density, high specific strength and specific stiffness, excellent castability and good processing performance, and also has good damping and shock absorption performance, which is very suitable for use as a door and window material. [0003] The current sound insulation of aluminum alloy doors and windows not only depends on the sound insulation performance of the door or window sashes, but also is seriously affected by the gap between the win...

Problems solved by technology

[0005] Aiming at the problems existing in the prior art, the object of the present invention is to provide an environmentally friendly sound-insulating aluminum alloy door and window, which can realize that when the external noise decibels are too large and the sound-proof glass cannot completely isolate the noise, by rotating the rotating rod, it can drive The universal joint rotates at the same time, so that the first rotating shaft connected to the universal joint drives the second rotating shaft to rotate, so that the two winding boxes at the outer end of the transmission shaft core wrap the lifting rope, and the two sound-proof The shape of the base of the sound-insulating board between the glasses changes, tending to a vertical state, and a sound-insulating layer is formed between the insides of the two sound-proof glasses to fit the inner wall, effectively avoiding the occurrence of noise infiltration, and at the same time, the inside of the base of the sound-proofing board The sound insulation cotton in the cavity weakens and attenuates the noise, so that the noise is not easy to spread to the room with excessive decibels, and this also forms a double-layer and multi-layer structure interlayer, which further strengthens the weakening and attenuation of sound transmission. At the same time, because the shape of the base of the sound insulation board tends to be vertical after the shape change, it also has a certain sun-shading effect on the outside world. When the outside temperature is high, it can also insulate the temperature, so that the indoor temperature is not easy to be too high. At night, there is no need to pull the curtains anymore. Under the shading effect of the base of the sound insulation board, it can shield the view and sound insulation when falling asleep at night. People can sleep more safely and save money. cost of materials for curtains
