Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum alloy windows, and specifically relates to an aluminum alloy window with sound insulation and noise reduction. Background Art

[0002] Aluminum alloy doors and windows refer to 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 for load-bearing rods (rods that bear and transmit deadweight and loads) and wood and plastic composites, referred to as aluminum-wood composite doors and windows and aluminum-plastic composite doors and windows. Aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), aluminum surface treatment and internal processing quality, and the price of aluminum alloy doors and windows. Aluminum alloy windows are windows with frames and sash structures made of aluminum alloy building profiles. They are divided into ordinary aluminum alloy doors and windows and broken bridge aluminum alloy doors and windows. Aluminum alloy windows are beautiful, sealed, and high in strength. They are widely used in the field of construction engineering. In home decoration, aluminum alloy doors and windows are often used to encapsulate balconies. The surface of aluminum alloy is oxidized and shiny. The aluminum alloy itself is easy to extrude, the cross-sectional dimensions of the profile are accurate, and the processing accuracy is high. Therefore, many owners choose to use aluminum alloy doors and windows in decoration.

[0003] At present, most of the aluminum alloy windows on the market are sliding windows. Sliding windows are simple and beautiful, with a wide field of view and high lighting rate. They open in one plane and take up little space. However, in order to facilitate the sliding of the windows, sliding windows usually have a certain gap between the two windows and cannot be completely sealed. Therefore, when residents need to rest in a quiet environment, they need to close the windows to isolate the noise. However, due to the gap between the joint of the two windows and between the aluminum alloy frame and the aluminum alloy window, external noise can easily be transmitted from the gap to the room, affecting the rest of the indoor residents. Therefore, a sound-insulating and noise-reducing aluminum alloy window is needed to reduce the impact of noise on residents. Summary of the invention

[0004] In order to overcome the problems existing in the background technology, the utility model provides a sound-insulated and noise-reducing aluminum alloy window. The aluminum alloy window can be easily installed into the aluminum alloy frame through the expansion and contraction action of the spring. The slide rail and the slide groove of the aluminum alloy window are tightly fitted through the self-gravity of the support plate and the slide rail, thereby reducing the impact of noise on residents.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0024] like Figure 1-7 As shown, the aluminum alloy window with sound insulation and noise reduction comprises an aluminum alloy frame 1 and two aluminum alloy windows 2. Seven groups of springs 3 are arranged on the upper part of the aluminum alloy frame 1. The upper end of the spring 3 is fixed inside the aluminum alloy frame 1. The lower end of the spring 3 is fixedly connected to a support plate 4. The lower end of the support plate 4 is connected to a slide rail 5 for fixing the aluminum alloy window 2 and sliding the upper part of the aluminum alloy window 2. The spring 3 is used to fix the support plate 4 and the slide rail 5, and the slide rail 5 is fitted with the aluminum alloy window 2 through the expansion and contraction of the spring 3 to reduce noise. The interior of the slide rail 5 is a cavity, and the cavity is filled with sound-absorbing cotton 14 to absorb part of the external noise and enhance the sound insulation effect of the aluminum alloy window. The support plate 4 is overlapped on both sides of the aluminum alloy frame 1, and the support plate 4 and the aluminum alloy frame 1 are installed with a second sound insulation cotton strip 10. The second sound insulation cotton strip 10 is arranged at the overlap of the support plate 4 and the aluminum alloy frame 1, and is squeezed downward by the elastic force of the spring 3 so that the second sound insulation cotton strip 10 blocks the gap between the support plate and the aluminum alloy frame 1, thereby enhancing the sound insulation performance of the aluminum alloy window.

[0025] An arc-shaped slide groove 6 matching the aluminum alloy window 2 is provided at the lower part of the aluminum alloy frame 1 to facilitate the sliding of the aluminum alloy window 2. A slide groove 7 matching the slide rail 5 is provided at the top of the aluminum alloy window 2, and a plurality of steel ball rollers 8 are fixedly installed at the bottom, rolling in the arc-shaped slide groove 6, and the steel ball rollers 8 roll in close contact with the arc-shaped slide groove 6. A cavity is provided in the inner window body at the junction of the two aluminum alloy windows 2, and a retractable first sound insulation cotton strip 9 is provided inside the cavity. A fixing plate 11 is provided on one side of the retractable first sound insulation cotton strip 9 for fixing the first sound insulation cotton strip 9, and the first sound insulation cotton strip 9 is retracted and retracted by a push-pull switch 12 fixed inside the aluminum alloy window 2. The push-pull switch 12 is a planar four-link structure, which is fixed inside the inner window of the aluminum alloy window 2, and includes a handle 121, a first link 122, a second link 123 and a push-pull rod 124. The right end of the handle 121 is fixed to the aluminum alloy window 2 through a pin, and both ends of the pin are fixedly connected to the aluminum alloy window 2. The first link 122 and the second link 123 are provided on both sides of the handle 121. One end of the two first links 122 is hinged through a pin, and both ends of the pin are fixed to the aluminum alloy window 2. The other end of the first link 122 is riveted to one end of the second link 123 and the handle 121, and the three can rotate relative to each other. The other ends of the two second links 123 are hinged to both sides of the push-pull rod 124, and can push the push-pull rod 124. The push-pull rod 124 of the push-pull switch 12 is fixedly connected to the fixed plate 11. When the window needs to be closed and quiet, the handle 121 of the push-pull switch 12 is pressed. The handle 121 can press the triangular first connecting rod 122 and the second connecting rod 123 downward to increase the angle between the two, and push the push-pull rod 124 out. The push-pull rod 124 pushes the fixed plate 11, and the first soundproof cotton strip 9 can be pushed out in its entirety to block the gap between the two aluminum alloy windows 2 and isolate the noise from outside. When the window is opened or the first soundproof cotton strip 9 is not needed, the first soundproof cotton strip 9 can be retracted into the aluminum alloy window 2 through the push-pull switch 12, which enhances the sealing of the two aluminum alloy windows 2, reduces noise, and is easy to use. An opening 13 is provided on the inner window of the aluminum alloy window 2 for facilitating the use of the push-pull switch 12, which is convenient for residents to operate.

[0026] The working process of this utility model:
