Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a high-strength noise-reducing aluminum alloy door and window. Background Art

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and sashes. Aluminum alloy doors and windows include doors and windows with aluminum alloy as the base material of the load-bearing rods (rods that bear and transmit deadweight and loads) and wood and plastic composite doors and windows, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. Aluminum alloy doors and windows are provided in five types: sliding aluminum alloy doors, sliding aluminum alloy windows, casement aluminum alloy doors, casement aluminum alloy windows and aluminum alloy floor spring doors.

[0003] During the use of aluminum alloy doors and windows, most of them are equipped with sealing strips at the closing part between the doors and windows and the frames to increase the sealing after the doors and windows are closed, thereby improving the noise reduction. However, the sealing strips are prone to deformation under long-term exposure to the outdoors and high temperature, resulting in a certain gap between the sealing strips and the doors and windows after closing, thereby reducing the noise reduction. In addition, most of them are simply noise-reducing through sealing, making it difficult to eliminate the noise that penetrates the doors and windows.

[0004] Therefore, the present application provides a high-strength noise-reducing aluminum alloy door and window to meet the needs. Utility Model Content

[0005] The utility model aims to solve the problems existing in the above-mentioned background technology and proposes a high-strength noise-reducing aluminum alloy door and window.

[0022] Aluminum alloy door and window main body 1, window frame 101, glass 102, door and window lock 103, air vent 104, sealing frame 2, sealing strip 201, spring 202, storage slot 3, sound-absorbing cotton 301, filter plate 4. DETAILED DESCRIPTION

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 A high-strength noise-reducing aluminum alloy door and window is shown, and an embodiment of the utility model provides, comprising: an aluminum alloy door and window body 1, a sealing frame 2 is fixedly connected to the rear end of the inner wall of the aluminum alloy door and window body 1, a window frame 101 is arranged on the left side of the inner wall of the aluminum alloy door and window body 1, a glass 102 is embedded in the window frame 101, a door and window lock 103 is installed on the right side of the window frame 101, air holes 104 are opened around the front of the aluminum alloy door and window body 1, a sealing strip 201 is embedded in the front of the sealing frame 2, a spring 202 is fixedly connected between the sealing strip 201 and the sealing frame 2, the outer side surface of the cross section of the aluminum alloy door and window body 1 is in a "concave" shape, and a filter plate 4 is embedded around the outer side surface of the aluminum alloy door and window body 1, and the filter plate 4 is connected to the inside of the storage tank 3;

[0024] When the window frame 101 is closed with the aluminum alloy door and window body 1, the rear end of the window frame 101 can be in contact with the front of the sealing frame 2 to form a seal, thereby increasing the sealing performance of the window frame 101 and the aluminum alloy door and window body 1 after closing, thereby improving the transmission of certain noises. At the same time, when the window frame 101 is in contact with the front of the sealing frame 2, the window frame 101 will increase the sealing performance through the sealing strip 201, and the sealing strip 201 will always be tightly fitted to one side of the window frame 101 through the elastic force of the spring 202, so that the window frame 101 and the sealing frame 2 are in close contact with each other. There is no sealing between the sealing strips 201, thereby increasing the sealing between the window frame 101 and the aluminum alloy door and window body 1 after closing, increasing the noise resistance, and when the noise is transmitted to the area around the aluminum alloy door and window body 1, it can enter the groove area around the aluminum alloy door and window body 1 through the air vents 104, and enter the storage slot 3 through the filter plate 4 and be adsorbed by the sound-absorbing cotton 301, thereby improving the adsorption of noise. At the same time, the filter plate 4 can prevent dust and mosquitoes from entering the storage slot 3, thereby increasing the service life of the sound-absorbing cotton 301.

[0025] In this embodiment, Figure 2-Figure 4 As shown;

[0026] The cross section of the sealing strip 201 is in a "concave" shape on the side away from the sealing frame 2;

[0027] When the concave-shaped sealing strip 201 contacts one side of the window frame 101, the sealing strip 201 can have a double contact surface with the contact surface of the window frame 101, thereby achieving double sealing, further improving the sealing performance;

[0028] A storage slot 3 is provided inside the main body 1 of the aluminum alloy door and window, and the inner wall of the storage slot 3 is fixedly connected with sound-absorbing cotton 301 arranged at equal distances;

[0029] When the aluminum alloy door and window body 1 is fixed to the required position, when the noise is transmitted to the surrounding area of ​​the aluminum alloy door and window body 1, the noise will be absorbed by the sound-absorbing cotton 301 in the storage groove 3, so that the aluminum alloy door and window body 1 can achieve a certain noise reduction performance;

[0030] The cross section of the sound-absorbing cotton 301 is wavy;

[0031] The wavy sound-absorbing cotton 301 can increase the contact surface with the noise, thereby increasing the adsorption of the sound-absorbing cotton 301 to noise, and further improving the overall noise reduction of the aluminum alloy door and window body 1.
