Made of aluminum alloy, they have low density and high strength, so they are structurally stable and durable. Soundproof aluminum alloy doors and windows can achieve soundproofing by installing sealing strips and double-layer glass. Sealing strips can effectively reduce the penetration of air and noise, while double-layer glass can reduce the propagation of sound waves. These doors and windows can not only effectively isolate noise, but also save energy and heat, and improve the quality of living. Soundproof aluminum alloy doors and windows also have beautiful appearance and a variety of design options to meet different needs. Consumer needs; In general, soundproof aluminum doors and windows are an excellent choice of windows suitable for a variety of environments and residential and commercial buildings; When using soundproof aluminum doors and windows, when opening and closing the aluminum doors and windows, the window body and the frame will collide, generating a lot of noise.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with the prior art, when preventing aluminum alloy doors and windows from colliding and making loud noises when opening and closing, sponge pads or rubber pads are used to buffer the aluminum alloy doors and windows to reduce the force during collision, thereby reducing the noise generated during collision. Sponge pads or rubber pads will block the aluminum alloy doors and windows, making it difficult to completely close the aluminum alloy doors and windows, resulting in poor sound insulation effect. The aluminum alloy doors and windows use air pressure to buffer the aluminum alloy doors and windows to reduce the noise generated during collision, and can be completely retracted without blocking the aluminum alloy doors and windows, so that the aluminum alloy doors and windows can be completely closed, and the sound insulation effect is better;

[0015] 3. By setting the mounting opening, the connecting spring and the friction block can be limited and accommodated. By setting the friction block, friction can be generated between the mounting frame and the mounting frame when the mounting frame slides in the limiting groove. The arc structure of the friction block cooperates with the connecting spring, so that when the moving speed of the mounting frame is low, the friction force and interaction force between the friction block and the mounting frame are small. When the moving speed of the mounting frame is fast, the friction force and interaction force between the friction block and the mounting frame are large, thereby achieving the effect of decelerating the mounting frame.
