Description

Technical Field

[0001] This invention relates to the field of aluminum alloy doors and windows, and in particular to a sound insulation structure for aluminum alloy doors and windows. Background Technology

[0002] With rapid urban development, noise from traffic, industrial production, and commercial activities is increasing daily, continuously impacting people's daily lives. Whether in residential or office spaces, the demand for quiet and comfortable indoor environments is growing stronger. As crucial channels connecting buildings to the outside world, the sound insulation capabilities of doors and windows directly affect the quality of the indoor acoustic environment. Therefore, improving the sound insulation performance of doors and windows is a key aspect of improving living and working environments. However, traditional aluminum alloy doors and windows have significant shortcomings in sound insulation. Aluminum alloy itself is a metallic material with strong sound conductivity, allowing sound to easily be transmitted directly through the profiles. Furthermore, the structural design of traditional doors and windows is relatively simple, with profiles often being single-cavity, glass typically using a single-layer design, and sealing structures that are also relatively basic, resulting in numerous gaps and poor sealing. This allows external noise to easily enter the room through the profiles, glass, and gaps, failing to meet people's basic need for a quiet environment. Therefore, improving the sound insulation structure of aluminum alloy doors and windows is essential.

[0003] A search revealed Chinese Patent Publication No. CN219387631U, which discloses an aluminum alloy door and window structure, including a top frame, side frames, and a lifting seat. The top and bottom outer walls of the side frames are integrally connected with protrusions that are inserted into the top frame, and a slot is provided on the outer wall of one side of the protrusion. The top frame has a movable cavity inside, and an insert is slidably connected inside the movable cavity. The insert is inserted into the slot. A return spring connected to the insert is welded to the inner wall of the movable cavity. A compression bolt is threadedly connected to the outer wall of one side of the top frame. This utility model uses a rotating extrusion bolt to drive an extrusion block to press the insert into the slot, thus pressing the insert into the slot. This allows for the connection and fixation between the side frame and the top frame without the use of multiple screws, making the installation process more convenient and improving installation efficiency. The motor drives the lead screw to rotate and connect with the threaded lifting block, which in turn drives the lifting seat and cleaning brush to move up and down, cleaning dust from both fixed and movable window sashes. However, aluminum alloy frames often suffer from noticeable metal sound transmission due to their single cavity and rigid connection, especially low-frequency vibration noise that is easily transmitted directly into the room through the profile. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a sound insulation structure for aluminum alloy doors and windows, aiming to improve the problem that aluminum alloy frames often have obvious metal sound transmission due to their single cavity and rigid connection, especially the problem that low-frequency vibration noise can be directly transmitted into the room through the profile.

[0012] The above technical solution involves a sponge attached to the front of the foam board, which effectively improves the overall comfort and sound insulation of the structure.

[0013] As a further description of the above technical solution: The fixing component includes two elastic columns, each with its adjacent side fixedly connected to the opposite side of the positioning rod. Each of the opposite sides of the elastic columns is fixedly connected to a locking block.

[0017] As a further description of the above technical solution: The rear side of the mounting frame is fixedly connected with indoor sealant, and the front side of the mounting frame is fixedly connected with weather-resistant sealant.

[0018] Through the above technical solution, the sealant has excellent sealing performance, which can effectively prevent indoor air leakage and moisture penetration, ensuring a comfortable and dry indoor environment. At the same time, a layer of weather-resistant sealant adapted to outdoor environments is also fixedly connected to the front side of the mounting frame. This weather-resistant sealant has excellent weather resistance, UV resistance and aging resistance, and can maintain a stable sealing effect under various harsh climatic conditions, preventing external wind and rain from intruding, thereby comprehensively improving the overall sealing performance and service life of the mounting frame.

[0019] As a further description of the above technical solution: A positioning post is fixedly connected to the bottom front side of the aluminum alloy frame, and positioning holes are present at the rear side of the window frame.

[0020] The above technical solution achieves a closing effect by engaging the positioning pin with the positioning hole during closure, thus enhancing the sealing performance and improving sound insulation.

[0021] This utility model has the following beneficial effects: 1. In this utility model, noise reduction is achieved by setting a multi-layer sound insulation structure for the aluminum alloy frame and soundproof glass. The sponge in the aluminum alloy frame can initially insulate the sound. After the noise propagates, it absorbs the residual scattered audio through the foam board by its own characteristics. Finally, the polyester fiber fabric mesh frame blocks all the volume. Butyl rubber is filled in the groove in the window frame, and then the soundproof glass is installed. The inner side of the soundproof glass also has a hollow argon gas layer, which can further improve the sound insulation effect.

[0022] 2. In this utility model, when it is necessary to open the window for ventilation, pushing the soundproof glass can drive the adjustment rod to rotate. The rotation of the adjustment rod causes the adjustment column to slide in the groove, which can adjust the opening size of the soundproof glass. When the verticality is achieved, the positioning rod can be pushed to support the adjustment column and achieve support at the position. At the same time, the locking block will extend out of the hole under the action of the elastic column, further improving the stability of the fixation. Attached Figure Description

[0034] Please see the appendix Figure 3 Appendix Figure 5 and attached Figure 6 A positioning post 5 is fixedly connected to the bottom front side of the aluminum alloy frame 1, and a positioning hole 6 is provided at the rear side of the window frame 4.

[0035] Working principle: Noise reduction is achieved by setting up a multi-layer sound insulation structure for the aluminum alloy frame 1 and the soundproof glass 202. The sponge 2063 inside the aluminum alloy frame 1 can initially insulate the sound. After the noise propagates, it absorbs the residual scattered audio through the foam board 2061 by its own properties. Finally, the polyester fiber fabric mesh frame 2062 blocks all the sound. Butyl glue 201 is filled in the groove inside the window frame 4, and then the soundproof glass 202 is installed, which can achieve the effect of waterproofing and gasproofing. The inner side of the soundproof glass 202 also has a hollow argon gas layer 203, which can further improve the sound insulation effect. At the same time, the outer side is fixedly connected with silicone structural glue 204, and the inner side is fixedly connected with fixing glue 205, which increases the sealing and enhances the bonding strength. When ventilation is needed, pushing the soundproof glass 202 will rotate the adjusting rod 301. The rotation of the adjusting rod 301 causes the adjusting column 302 to slide within the slide groove 303, adjusting the opening size of the soundproof glass 202. When verticality is achieved, the positioning rod 304 can be pushed to support the adjusting column 302, thus providing support for its position. At the same time, the locking block 3062 will extend out of the hole 3063 under the action of the elastic column 3061, further improving the stability of the fixation. During installation, the mounting frame 3071 can be initially fixed in the required position using the fastening bolt 3072, and the sealing performance of the structure can be improved while enhancing the fixing effect using indoor sealant 3073 and weather-resistant sealant 3074.
