Technical Field

[0001] This utility model relates to the field of door and window equipment technology, and more specifically, to an airtight and soundproof aluminum alloy folding door and window. Background Technology

[0002] In modern architecture, doors and windows, as an important part of the building envelope, undertake the basic functions of lighting and ventilation. With the improvement of people's living standards and the continuous improvement of requirements for indoor environmental quality, higher requirements are put forward for the airtightness and sound insulation performance of doors and windows. Especially in some noise-sensitive places, such as bedrooms, studies, hospital wards, and school classrooms, doors and windows need to effectively block external noise and create a quiet and comfortable indoor environment for people.

[0003] A search revealed that Chinese patent CN218293323U discloses "a folding door and window, comprising a window body, an upper support rod, and a lower support rod. The upper support rod is located above the window body, and the lower support rod is located at the bottom of the window body. A window assembly is located between the upper and lower support rods. The window assembly can be folded and pushed / pulled. The window assembly includes a first vertical support rod, a second vertical support rod, a first window, a second window, a third window, a fourth window, and a first pulley. The first vertical support rod is located on one side inside the window body. This utility model, through the cooperative use of the upper support rod, lower support rod, first vertical support rod, second vertical support rod, first window, second window, third window, fourth window, first pulley, mounting post, mounting groove, movable base, and second pulley, allows the entire window to be freely moved and opened or closed, achieving maximum ventilation and sunlight penetration, and enhancing the window's usability." However, it still has the following drawbacks: This device cannot effectively block external noise during use, especially when the windows are closed. The gaps between the windows allow external noise to enter the room directly, affecting both the quietness of the indoor environment and the comfort of use. Therefore, an airtight, sound-insulating aluminum alloy folding door and window is proposed. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing technologies cannot effectively block external noise, especially when windows are closed, as gaps between windows allow external noise to directly enter the room, affecting both the quietness of the indoor environment and the comfort of use. This invention provides an airtight, soundproof aluminum alloy folding door / window to solve the problems mentioned in the background.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: an airtight and soundproof aluminum alloy folding door and window, comprising an aluminum alloy frame, wherein the interior of the aluminum alloy frame is provided with a soundproofing component for soundproofing the gap between the folding door and window, and a limiting component for limiting the folding door and window is provided on one side of the aluminum alloy frame. The sound insulation component includes a fixing frame fixedly connected to the inner wall of an aluminum alloy frame. Two sound insulation cottons are provided between the aluminum alloy frame and the fixing frame. Four connecting frames are slidably connected to the inner wall of the fixing frame. The inner walls of the four connecting frames are all provided with acoustic glass. Two magnetic sealing strips are provided on the adjacent side walls of the four connecting frames. A handle is fixedly connected to one side of each connecting frame.

[0006] As a preferred technical solution of this utility model, the limiting component includes a guide rail fixedly connected to one side of the aluminum alloy frame, a limiting block slidably connected to the inner wall of the guide rail, a plurality of limiting holes opened on the outer wall of the guide rail, two limiting plates hinged to one side of the limiting block, a fixing post fixedly connected to one side of the two limiting plates, a folding plate hinged to one side of the limiting block, and the side of the folding plate away from the limiting block fixedly connected to one side of the connecting frame.

[0007] As a preferred technical solution of this utility model, baffles are bolted to the outer walls of the four connecting frames, and the four baffles are evenly distributed along the height direction of the connecting frames.

[0008] As a preferred technical solution of this utility model, the inner wall of the limiting block is fixedly connected to multiple rotating shafts, and the outer walls of the multiple rotating shafts are rotatably connected to rollers.

[0009] As a preferred technical solution of this utility model, a spring is fixedly connected to the inner wall of the guide rail, and a push plate is fixedly connected to the end of the spring away from the guide rail.

[0010] As a preferred technical solution of this utility model, a fixing plate is bolted to one side of the aluminum alloy frame, and an arc-shaped plate is fixedly connected to one side of the fixing plate.

The sound insulation cotton filled between the aluminum alloy frame and the fixing frame provides a good sound insulation effect for the aluminum alloy frame, effectively blocking the transmission of sound. The connecting frame and acoustic glass work together to further block external noise. The mutual adsorption of the magnetic sealing strips in the adjacent connecting frames not only enhances the airtightness between the connecting frames and prevents air leakage, but also improves the sound insulation effect.

[0013] 2. By setting the limiting components, the connecting frame is stably limited at different positions within the fixed frame. The connecting frame moves within the guide rail by driving the limiting block through the folding plate. The opening and closing degree of the connecting frame is limited by the cooperation of the fixed post and the limiting hole on the limiting plate, effectively preventing the connecting frame from opening or closing excessively or shaking, and improving the safety and stability of the connecting frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 As shown, this embodiment proposes an airtight and soundproof aluminum alloy folding door and window, including an aluminum alloy frame 1, a soundproof component 2 for soundproofing the gap between the folding door and window is provided inside the aluminum alloy frame 1, and a limiting component 3 for limiting the folding door and window is provided on one side of the aluminum alloy frame 1. like Figure 2 and Figure 3 As shown, the sound insulation component 2 includes a fixing frame 201 fixedly connected to the inner wall of the aluminum alloy frame 1. Two sound insulation cotton 202s are disposed between the aluminum alloy frame 1 and the fixing frame 201. The heat insulation and sound insulation cotton 202s are made of high-density rock wool. Through the sound insulation cotton 202s between the aluminum alloy frame 1 and the fixing frame 201, sound transmission can be effectively absorbed and blocked, while reducing heat transfer. Four connecting frames 203 are slidably connected to the inner wall of the fixing frame 201. The inner walls of the four connecting frames 203 are all provided with acoustic glass 204. The two adjacent sides are hinged to each other. The top and bottom of the connecting frame 203 are slidably connected to the inner top wall and inner bottom wall of the fixing frame 201, respectively. The acoustic glass 204 inside the connecting frame 203 further enhances the sound insulation effect and effectively reduces the external noise entering the room. Two magnetic sealing strips 205 are provided on the adjacent side walls of the four connecting frames 203. The magnetic sealing strips 205 on the adjacent inner walls of the connecting frame 203 attract each other to prevent air leakage and also improve the sound insulation performance. A handle 206 is fixedly connected to one side of the connecting frame 203. The fixing frame 201 inside the aluminum alloy frame 1 provides stable support for the aluminum alloy frame 1. At the same time, the high-density rock wool sound insulation cotton 202 between the aluminum alloy frame 1 and the fixing frame 201 effectively absorbs and blocks sound transmission while reducing heat transfer. The connecting frame 203 provides stable support for the acoustic glass 204. The acoustic glass 204 on the connecting frame 203 can block and absorb sound, further enhancing the sound insulation effect. By pulling the connecting frame 203 with the handle 206, the connecting frame 203 can slide smoothly along the inner wall of the fixing frame 201, realizing the folding and opening of the connecting frame 203 and the acoustic glass 204. In the fully closed state, the magnetic sealing strips 205 on the adjacent sides of the connecting frame 203 are tightly attracted under the action of magnetic force, forming a gapless seal. This not only prevents external noise from leaking into the room through the gaps between the connecting frames 203, but also greatly enhances the airtightness of the connecting frame 203, prevents air leakage, and greatly improves the sound insulation effect.

[0018] like Figure 4 As shown, the limiting component 3 includes a guide rail 301 fixedly connected to one side of the aluminum alloy frame 1. A limiting block 302 is slidably connected to the inner wall of the guide rail 301. Multiple limiting holes 303 are opened on the outer wall of the guide rail 301. Two limiting plates 304 are hinged to one side of the limiting block 302. A fixing post 305 is fixedly connected to one side of the two limiting plates 304. A folding plate 306 is hinged to one side of the limiting block 302. The side of the folding plate 306 away from the limiting block 302 is fixedly connected to one side of the connecting frame 203. When the connecting frame 203 moves, it drives the folding plate 306 to extend and retract, thereby pushing or pulling the limiting block 302 to slide on the guide rail 301. By rotating the limiting plate 304, the fixing post 305 on the limiting plate 304 is inserted into the limiting hole 303, thereby stably limiting and fixing the connecting frame 203. During the movement of the connecting frame 203, the folding plate 306 will be driven to extend and retract synchronously, thereby driving the limiting block 302 to slide smoothly along the inside of the guide rail 301. When the connecting frame 203 moves to the preset position, the limiting plate 304 on the limiting block 302 is rotated, so that the fixing post 305 on the limiting plate 304 is inserted into the corresponding limiting hole 303 on the guide rail 301. This effectively limits the displacement of the limiting block 302 on the guide rail 301 and controls the movement range of the connecting frame 203. This not only prevents the connecting frame 203 from excessive displacement due to external forces, but also avoids the risk of derailment of the connecting frame 203 during movement, significantly improving the safety and stability of the connecting frame 203 during operation.

[0019] like Figure 2 As shown, baffles 4 are bolted to the outer walls of the four connecting frames 203, and the four baffles 4 are evenly distributed along the height direction of the connecting frames 203. When the connecting frames 203 are in the closed state, the baffles 4 on the connecting frames 203 improve the stability of the connecting frames 203, which not only effectively distributes the impact of external wind pressure on the connecting frames 203, but also prevents the connecting frames 203 from vibrating or deforming under strong wind conditions, thereby significantly extending the service life and durability of the connecting frames 203.

[0020] like Figure 5 As shown, multiple rotating shafts 5 are fixedly connected to the inner wall of the limiting block 302, and rollers 6 are rotatably connected to the outer walls of the multiple rotating shafts 5. When the limiting block 302 slides within the guide rail 301, the rollers 6 roll on the inner wall of the guide rail 301, greatly reducing the friction between the limiting block 302 and the guide rail 301, making the sliding of the limiting block 302 smoother. This not only improves the smoothness of opening and closing the connecting frame 203, but also extends the service life of the limiting block 302 and the guide rail 301, and reduces maintenance costs.

[0021] like Figure 5As shown, a spring 7 is fixedly connected to the inner wall of the guide rail 301, and a push plate 8 is fixedly connected to the end of the spring 7 away from the guide rail 301. During the sliding process of the limiting block 302, the spring 7 provides a certain buffering effect on the limiting block 302 through the push plate 8. When the connecting frame 203 is fully unfolded, it can effectively absorb the impact force between the limiting block 302 and the end of the guide rail 301, avoiding the vibration caused by the collision between the limiting block 302 and the guide rail 301. The vibration is transmitted to the connecting frame 203 through the folding plate 306, which greatly extends the service life of the limiting block 302 and the guide rail 301.

[0022] like Figure 2 As shown, a fixing plate 9 is bolted to one side of the aluminum alloy frame 1, and an arc-shaped plate 10 is fixedly connected to one side of the fixing plate 9. The arc-shaped plate 10 on the fixing plate 9 can effectively block external dust or direct sunlight from shining on the acoustic glass 204, while guiding the airflow around the aluminum alloy frame 1, reducing airflow turbulence, reducing wind noise, improving the usage environment of the acoustic glass 204, and providing users with a quieter and more comfortable experience.

[0023] like Figure 3 As shown, soundproof sealing strips 11 are provided on both opposite sides of the four connecting frames 203, and multiple soundproof sealing strips 11 are located at the junction of the connecting frames 203 and the acoustic glass 204. The soundproof sealing strips 11 can fill the gap between the connecting frames 203 and the acoustic glass 204, preventing sound and air from leaking from the gap, and greatly improving the airtightness and sound insulation of the doors and windows.

[0024] Specifically, in use, this airtight and soundproof aluminum alloy folding door and window works as follows: The fixing frame 201 within the aluminum alloy frame 1 provides stable support for the frame. Simultaneously, the high-density rock wool sound insulation cotton 202 between the aluminum alloy frame 1 and the fixing frame 201 effectively absorbs and blocks sound transmission while reducing heat transfer. The connecting frame 203 provides stable support for the acoustic glass 204. The acoustic glass 204 on the connecting frame 203 blocks and absorbs sound, further enhancing the sound insulation effect. Pulling the connecting frame 203 via the handle 206 allows it to slide smoothly along the inner wall of the fixing frame 201, enabling the folding and opening of the connecting frame 203 and the acoustic glass 204. When the connecting frame 203 is fully closed, the magnetic sealing strips 205 on adjacent sides of the connecting frame 203 are tightly attracted under magnetic force, forming a gapless seal. This not only prevents external noise from leaking into the room through gaps between the connecting frames 203 but also significantly enhances the airtightness of the connecting frame 203, preventing air leakage (such as...). Figure 2 and Figure 3As shown); during the movement of the connecting frame 203, the folding plate 306 will simultaneously extend and retract, thereby driving the limiting block 302 to slide smoothly along the inside of the guide rail 301. When the connecting frame 203 moves to the preset position, the limiting plate 304 on the limiting block 302 is rotated, so that the fixing post 305 on the limiting plate 304 is inserted into the corresponding limiting hole 303 on the guide rail 301, effectively limiting the displacement of the limiting block 302 on the guide rail 301, and also controlling the movement range of the connecting frame 203 (e.g. Figure 4 (As shown in the figure) This not only improves the safety and stability of the connecting frame 203 during operation, but also significantly enhances the sound isolation effect.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
