Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular to a sound-absorbing aluminum alloy door and window. Background Technology

[0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, mullions, and sashes. They are commonly referred to as aluminum doors and windows and can be used in high-rise buildings, luxury hotels, shops, and residential buildings. Due to their excellent performance and diverse applications, aluminum alloy doors and windows occupy an important position in the construction industry.

[0003] In the prior art, a patent publication number (CN221469753U) describes an aluminum alloy door and window, which includes: a cleaning frame movably installed on the back of the window body; the window body includes a frame; glass is fixedly installed inside the frame; mounting grooves are provided on both sides of the frame; the frame includes side boxes on both sides; mounting strips are fixedly installed on the surface of the two side boxes and are movably installed into the mounting grooves; and motors are fixedly installed on the top of the interior of the two side boxes. This invention uses a motor to drive a threaded screw to rotate, which in turn drives a slider to move up and down. Simultaneously, the slider can synchronously drive a moving block to move, facilitating thorough cleaning of the glass surface. However, when the door and window are closed, this type of device does not have a positioning and reinforcement structure added to its rear side. Therefore, when the aluminum alloy door and window are closed, the hinge mounting part on the aluminum alloy window frame will have reduced stability in strong winds, which may cause it to open while closed, thus reducing the service life of the window. Utility Model Content

[0004] The purpose of this utility model is to provide a sound-absorbing aluminum alloy door and window to solve the problem that when such devices are closed, there is no positioning and reinforcement structure added to the rear side of the door and window. As a result, when the aluminum alloy door and window are closed, the hinge installation part on the aluminum alloy window frame will reduce stability in a strong wind environment, and may open when closed, thus reducing the service life of the window.

[0005] To achieve the above objectives, a sound-absorbing aluminum alloy door and window is provided, including an outer frame, an inner frame, a main body, and a handle. The inner frame has a positioning structure at all four ends of its back, each including a positioning corner block. Multiple positioning corner blocks are fixed to the back of the inner frame. A shock-absorbing block is fixed to the inner side of each positioning corner block, and a positioning support block is fixed to the front end of each shock-absorbing block. All positioning support blocks are abutted against the back of the main body.

[0006] According to the aforementioned sound-absorbing aluminum alloy door and window, a first sound-absorbing strip is fixed to both the inner side of the outer frame of the door and window and the left and right ends of the outer side of the inner frame of the door and window, and a second sound-absorbing strip is fixed to both the upper and lower ends of the inner side of the outer frame of the door and window and the outer side of the inner frame of the door and window, and both the first sound-absorbing strip and the second sound-absorbing strip are arranged in a square shape.

[0007] According to the aforementioned sound-absorbing aluminum alloy door and window, the outer frame of the door and window is fixed with plug-in blocks on all four sides, and the length of the plurality of plug-in blocks is the same as the length of the outer side of the door and window frame.

[0008] According to the aforementioned sound-absorbing aluminum alloy door and window, both the first and second sound-absorbing strips have meshing grooves on their outer surfaces, and the plurality of meshing grooves are all obliquely shaped.

[0009] According to the aforementioned sound-absorbing aluminum alloy door and window, a connector strip is fixed between the two connector blocks along the horizontal direction.

[0010] According to the aforementioned sound-absorbing aluminum alloy door and window, a perforation hole extends through the bottom inner side of the inner frame of the door and window, and multiple perforations extend through to the bottom outer frame of the door and window.

[0011] According to the aforementioned sound-absorbing aluminum alloy door and window, multiple of the plug-in blocks have threaded holes penetrating their exteriors.

[0012] According to the aforementioned sound-absorbing aluminum alloy door and window, the inner sides of both the first and second sound-absorbing strips are smoothly arranged.

[0013] The above solution offers the following advantages: When the main body of the door and window is closed by rotating the handle, its back is tightly fitted with multiple positioning support blocks on the back of the inner frame of the door and window. The positioning support blocks are rigidly connected to the inner frame of the door and window through shock-absorbing blocks and positioning corner blocks, forming a multi-directional support structure. When strong winds impact the main body of the door and window, the pressure is transmitted to the shock-absorbing blocks through the positioning support blocks. The elastic deformation of the blocks absorbs the vibration energy and distributes it to the entire inner frame of the door and window through the positioning corner blocks, reducing stress concentration at the hinges and preventing accidental opening. The welding and fixing of the positioning corner blocks to the inner frame of the door and window provides durable support, preventing structural loosening due to repeated opening and closing and extending service life. At the same time, the first and second sound-absorbing strips are used to form a square sealing ring with oblique meshing grooves on the outside, causing sound waves to reflect and interfere with each other multiple times, reducing the intensity of mid-to-high frequency noise. Finally, the use of pins screwed into the threaded holes enables rapid installation and meets high load-bearing requirements. When rainwater seeps into the bottom of the inner frame of the door and window through the gaps in the main body, it is directed to the outside of the outer frame of the door and window through the drainage holes, preventing water accumulation and corrosion of the structure.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] Reference Figure 1-5This utility model discloses a sound-absorbing aluminum alloy door and window, comprising an outer frame 1, an inner frame 2, a main body 3 rotatably connected to the inner frame 2, a handle 4 on the outer side of the main body 3, and positioning structures at all four ends of the back of the inner frame 2. Each positioning structure includes positioning corner blocks 5, which are fixed to the back of the inner frame 2. An anti-vibration block 6 is fixed inside each positioning corner block 5, and a positioning support block 7 is fixed to the front end of each anti-vibration block 6. All positioning support blocks 7 are abutted against the back of the main body 3. In the prior art, such devices do not have a positioning and reinforcement structure on the rear when the door and window are closed, resulting in the aluminum alloy window frame... Hinges can become less stable in windy conditions, potentially causing them to open even when closed, thus reducing the lifespan of the window. To address this, positioning structures can be installed around the four ends of the back of the inner frame 2 of the door / window. After the main body 3 of the door / window is rotated and closed, the positioning corner blocks 5 with shock-absorbing blocks 6 on the four sides of the back of the inner frame 2 maintain the overall stability of the inner frame 2. Simultaneously, after closing, multiple positioning support blocks 7 are attached to the back of the main body 3 of the door / window, fitting the main body 3 against the front of the positioning support blocks 7. The positioning corner blocks 5 and shock-absorbing blocks 6 apply support to the back of the positioning support blocks 7, thereby supporting the back of the main body 3 of the door / window and improving the overall stability of the main body 3 of the door / window.

[0019] First sound-absorbing strips 8 are fixed to the inner side of the outer frame 1 and the left and right ends of the outer side of the inner frame 2 of the door and window. Second sound-absorbing strips 9 are fixed to the upper and lower ends of the inner side of the outer frame 1 and the outer side of the inner frame 2 of the door and window. Both the first sound-absorbing strips 8 and the second sound-absorbing strips 9 are square. By setting the two first sound-absorbing strips 8 and the second sound-absorbing strips 9, the sound absorption effect can be enhanced when the main body of the door and window 3 is closed, and noise can be avoided.

[0020] All four sides of the outer side of the door and window frame 1 are fixed with plug-in blocks 10. The length of the plug-in blocks 10 is the same as the length of the outer side of the door and window frame 1, so as to achieve the effect of snapping and fixing the outer side of the door and window frame 1. The two first sound-absorbing strips 8 and the second sound-absorbing strips 9 are all provided with meshing grooves 11. The meshing grooves 11 are all obliquely opened, which can reduce sound reflection and achieve the effect of noise reduction.

[0021] A connector strip 12 is fixed between two horizontal connector blocks 10 to reinforce the connection between the two connector blocks 10. A leakage hole 13 is passed through the bottom of the inner side of the inner frame 2 of the door and window. Multiple leakage holes 13 pass through to the bottom of the outer frame 1 of the door and window, so that the accumulated rainwater can be leaked when the main body 3 of the door and window is opened.

[0022] Multiple plug-in blocks 10 have threaded holes 14 through their exteriors, which facilitates the insertion of pins into the threaded holes 14, enabling the door and window frame 1 to be reinforced to a specific position. The inner sides of the two first sound-absorbing strips 8 and the second sound-absorbing strips 9 are both smoothly designed to avoid wear on the exterior of the door and window body 3.

[0023] Working principle: When the door and window body 3 is closed by rotating the handle 4, its back is tightly fitted with multiple positioning support blocks 7 on the back of the inner frame 2 of the door and window. The positioning support block 7 is rigidly connected to the inner frame 2 of the door and window through the shock-absorbing block 6 and the positioning corner block 5, forming a multi-directional support structure. When strong winds impact the main body 3 of the door and window, the pressure is transmitted to the shock-absorbing block 6 through the positioning support block 7. Its elastic deformation absorbs the vibration energy and disperses it to the whole of the inner frame 2 of the door and window through the positioning corner block 5, reducing the stress concentration at the hinge and preventing accidental opening. The welding and fixing of the positioning corner block 5 to the inner frame 2 of the door and window provides a lasting support force, avoiding structural loosening due to repeated opening and closing, and extending the service life. At the same time, the first sound-absorbing strip 8 and the second sound-absorbing strip 9 form a square sealing ring, with an oblique meshing groove 11 on its outer side, so that the sound waves are reflected multiple times and interfere with each other, reducing the intensity of mid-to-high frequency noise. Finally, the pin is screwed into the threaded hole 14 to achieve quick installation and high load-bearing requirements. When rainwater seeps into the bottom of the inner frame 2 of the door and window along the gap of the main body 3 of the door and window, it is directed to the outside of the outer frame 1 of the door and window through the drain hole 13, avoiding water accumulation and corrosion of the structure.

[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
