Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and more specifically, to multi-layer hollow sealed soundproof aluminum alloy doors and windows. Background Technology

[0002] With the continuous acceleration of urbanization, urban noise pollution has become increasingly serious. Aluminum alloy doors and windows, including those with aluminum alloy as the load-bearing member material and those made of wood or plastic composites, are widely used in the construction field due to their advantages such as high strength, corrosion resistance, and aesthetics.

[0003] However, currently, aluminum alloy doors and windows do not have good sound insulation. Sound insulation is usually achieved through the soundproof glass of aluminum alloy doors and windows. External noise can still penetrate into the room through the gaps between the doors and windows. At the same time, the sound insulation effect of aluminum alloy material is not strong, and noise can also be transmitted into the room through the aluminum alloy door frame, resulting in the poor sound insulation performance of aluminum alloy doors and windows, which affects people's rest.

[0004] A search revealed that Chinese patent CN221546797U discloses a soundproof aluminum alloy door and window. This structure connects the sealing plate to the aluminum alloy door frame by inserting four sets of posts fixed to the outer surface of the sealing plate into four sets of slots on the outer surface of the aluminum alloy door frame. By rotating bolts, the bolts are driven into the inner side of the bolt grooves, thus fixing the aluminum alloy door frame to the sealing plate. This seals the gap between the window frame and the aluminum alloy door frame, preventing external noise from penetrating into the room and disturbing people's rest. Furthermore, by installing sound-absorbing cotton and sound-absorbing panels on the inner side of the aluminum alloy door frame, it absorbs noise, improving the noise isolation effect and preventing noise from entering the room and disturbing people's rest due to the material of the aluminum alloy door frame.

[0005] However, in actual use, this structure relies solely on the sound insulation cotton and sound insulation board on the inner side of the aluminum alloy door frame for sound insulation. From the perspective of sound insulation materials, although the sound insulation cotton and sound insulation board have a certain sound absorption capacity, the single material lacks comprehensiveness in blocking different frequencies of sound and is difficult to achieve all-round interception. Some high-frequency noise can easily continue to spread through the gaps in the board. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-layer hollow sealed soundproof aluminum alloy door and window to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A multi-layer hollow sealed soundproof aluminum alloy door and window includes a window frame, a window sash is hinged inside the window frame, a fixed glass is embedded inside the window sash, and a soundproofing mechanism is installed inside the fixed glass;

[0009] The sound insulation mechanism includes a first glass fixedly embedded inside the window sash, a second glass disposed between the fixed glass and the first glass, a first hollow cavity disposed between the fixed glass and the second glass, and a second hollow cavity disposed between the first glass and the second glass, both the first hollow cavity and the second hollow cavity being filled with argon gas.

[0010] A fixing frame is fixedly installed on one side of the window frame, a sealing layer is fixedly installed on one side of the fixing frame, and a handle is fixedly installed on the surface of the window sash.

[0011] By adopting the above technical solution: multi-layer hollow glass filled with argon gas, combined with medium-density fiber sound insulation board, noise is reduced layer by layer, achieving efficient sound insulation and creating a quiet, comfortable and durable living environment for users.

[0012] As a further description of the above technical solution: a sealing mechanism is provided on one side of the window frame, the sealing mechanism includes a connecting strip fixedly disposed on one side of the window frame, the surface of the connecting strip is provided with a plurality of fixing grooves, and a fixing block is inserted into the inside of the fixing groove;

[0013] A sealing frame is fixedly installed on one side of the fixing block, and a sealing strip is inserted into the inside of the sealing frame. One side of the sealing strip is connected to the surface of the window sash.

[0014] By adopting the above-mentioned technical solution—the combined design of connecting strips, fixing grooves, and fixing blocks—the sealing frame can be stably installed and precisely positioned, and the sealing position can be flexibly adjusted. Moreover, the sealing strip fits tightly with the window sash, forming multiple layers of tight defense in conjunction with the sealing layer of the fixing frame. This effectively prevents noise, rainwater, dust, and other elements from entering the room through gaps, significantly improving the sound insulation, waterproofing, and dustproofing performance of doors and windows. At the same time, the modular sealing components are easy to disassemble and replace, reducing later maintenance costs and ensuring that doors and windows maintain a good sealing condition for a long time, continuously creating a quiet and clean indoor environment for users.

[0015] As a further description of the above technical solution: the surfaces of the fixing block and the connecting strip are both provided with threaded grooves, and bolts are threadedly connected inside the threaded grooves. The interior of the window sash is provided with an installation groove, and a first sound insulation board is fixedly installed inside the installation groove. The first sound insulation board is made of medium density fiber material.

[0016] The window frame has a slot inside, and a second sound insulation board is fixedly installed inside the slot. Sound insulation cotton is fixedly installed on one side of the second sound insulation board. Both the window frame and the window sash are made of aluminum alloy.

[0017] By adopting the above technical solutions, the aluminum alloy window frames and sashes are strong and corrosion-resistant, ensuring a stable and durable structure. In addition, the multiple sound-absorbing design of the medium-density fiber first sound insulation board, the second sound insulation board, and the sound insulation cotton forms a highly efficient sound insulation system, which significantly reduces noise transmission.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. By setting up a sound insulation mechanism, compared with existing technologies, the triple-glazed glass and double-hollow argon-filled structure utilizes the principle of reflection and refraction of sound when it propagates in different media to consume sound energy multiple times. Combined with the sound absorption characteristics of the medium-density fiber first sound insulation board inside the window sash, it achieves high-efficiency sound insulation. In terms of heat preservation, the low thermal conductivity of argon acts as a natural heat insulation layer. Combined with the internal cavity design of the window frame, it effectively blocks the heat conduction path, significantly reduces the exchange of heat between indoors and outdoors, and reduces the frequency and energy consumption of air conditioning and heating. In addition, the high-strength and corrosion-resistant aluminum alloy material, combined with the scientific window frame and sash structure design, not only enhances the overall stability of the doors and windows, but also resists the erosion of harsh environments, ensuring that the doors and windows are not easily deformed or damaged during long-term use. It comprehensively creates a quiet, comfortable, and durable living and working environment for users.

[0020] 2. By setting up a sealing mechanism, compared with existing technologies, the residual noise weakened by the double-layer hollow cavity encounters the medium-density fiber first sound insulation board inside the window sash. Its porous structure strongly absorbs sound energy, further reducing the noise intensity. Moreover, the combination of connecting strips, fixing blocks and bolts firmly fixes the sealing frame. When the window sash is closed, the sealing strip is tightly embedded in the sealing frame, forming multiple barriers with the side sealing layer of the fixed frame, preventing noise from entering through gaps. Even if a very small amount of sound manages to pass through the window sash, the second sound insulation board and sound insulation cotton inside the window frame will completely absorb it, further enhancing the sound insulation effect. At the same time, the tight sealing structure can also effectively block rainwater and dust from entering, keeping the room clean. Attached Figure Description

[0027] 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.

[0028] The embodiments disclosed in this application are as follows: Figures 1-5 The multi-layer hollow sealed soundproof aluminum alloy door and window shown includes a window frame 1, a window sash 2 is hinged inside the window frame 1, a fixed glass 3 is embedded inside the window sash 2, and a soundproofing mechanism is installed inside the fixed glass 3.

[0029] The sound insulation mechanism includes a first glass 4 fixedly embedded inside the window sash 2, a second glass 5 disposed between the fixed glass 3 and the first glass 4, a first hollow cavity 6 disposed between the fixed glass 3 and the second glass 5, and a second hollow cavity 7 disposed between the first glass 4 and the second glass 5. The interiors of the first hollow cavity 6 and the second hollow cavity 7 are both filled with argon gas.

[0030] A fixed frame 8 is fixedly installed on one side of the window frame 1, a sealing layer 9 is fixedly installed on one side of the fixed frame 8, and a handle 10 is fixedly installed on the surface of the window sash 2.

[0031] Fix the window frame 1 in the preset installation position to ensure it is stable and level. Install the window sash 2 inside the window frame 1 using hinge components to ensure that the window sash 2 can open and close flexibly.

[0032] The first glass 4, the second glass 5 and the fixed glass 3 are sequentially embedded inside the window sash 2 to form the first hollow cavity 6 and the second hollow cavity 7. Argon gas is then filled into the two hollow cavities. The low thermal conductivity of argon gas can effectively block heat transfer and improve the sound insulation effect.

[0033] When external noise travels to the doors and windows, it first comes into contact with the glass assembly consisting of fixed glass 3, second glass 5 and first glass 4. Because the surface of fixed glass 3 has a high density, when the sound hits the surface of fixed glass 3, some of the sound energy will be directly reflected back due to the obstruction of the surface of fixed glass 3 and cannot enter the room.

[0034] Furthermore, the unreflected sound penetrates the fixed glass 3 and enters the first hollow cavity 6. The argon gas filling the first hollow cavity 6 has a different acoustic impedance than both the glass and the air. At the interface between the glass and the argon gas, the sound is refracted and reflected, consuming some energy. Then the sound continues to propagate, penetrates the second glass 5, and enters the second hollow cavity 7. In the second hollow cavity 7, the sound is again refracted and reflected due to the presence of argon gas, further consuming energy.

[0035] Reference Figures 2-3 As shown, a sealing mechanism is provided on one side of the window frame 1. The sealing mechanism includes a connecting strip 11 fixedly installed on one side of the window frame 1. Multiple fixing grooves 12 are opened on the surface of the connecting strip 11, and fixing blocks 13 are inserted into the inside of the fixing grooves 12.

[0036] A sealing frame 14 is fixedly installed on one side of the fixing block 13, and a sealing strip 15 is inserted into the inside of the sealing frame 14. One side of the sealing strip 15 is connected to the surface of the window sash 2.

[0037] Fix the connecting strip 11 to one side of the window frame 1, insert the fixing block 13 into the fixing groove 12 of the connecting strip 11, so that the sealing frame 14 on one side of the fixing block 13 is initially positioned, and then tighten the bolt 16 through the threaded groove on the surface of the fixing block 13 and the connecting strip 11 to fix the sealing frame 14 to one side of the connecting strip 11.

[0038] Then, when the window sash 2 is closed, the sealing strip 15 is inserted into the interior of the sealing frame 14 to ensure the sealing between the window sash 2 and the window frame 1 when closed. In addition, together with the sealing layer 9 on one side of the fixed frame 8, multiple sealing defenses are formed to completely seal the gap between the window frame 1 and the window sash 2, preventing sound from entering the room through the gap.

[0039] Reference Figures 4-5 As shown, the surfaces of the fixing block 13 and the connecting strip 11 are both provided with threaded grooves, and the bolts 16 are threadedly connected inside the threaded grooves. The window sash 2 is provided with an installation groove, and a first sound insulation board 17 is fixedly installed inside the installation groove. The first sound insulation board 17 is made of medium density fiber material.

[0040] The window frame 1 has a slot inside, and a second sound insulation board 18 is fixedly installed inside the slot. Sound insulation cotton 19 is fixedly installed on one side of the second sound insulation board 18. Both the window frame 1 and the window sash 2 are made of aluminum alloy.

[0041] After being weakened by the two hollow cavities, a small amount of sound still penetrates the first glass 4. At this time, the first sound insulation board 17 made of medium density fiber material in the mounting groove inside the window sash 2 plays a role. The porous structure of the medium density fiber material can absorb sound and further dissipate the remaining sound energy.

[0042] If a very small amount of sound still penetrates the window sash 2, the second sound insulation board 18 and sound insulation cotton 19 placed in the slot of the window frame 1 will undergo final sound insulation treatment. The sound absorption characteristics of the second sound insulation board 18 and sound insulation cotton 19 can absorb the residual sound, ensuring that the noise entering the room is reduced to the minimum, and further enhancing the sound insulation performance.

[0043] Working principle of this utility model:

[0044] This utility model is a multi-layer hollow sealed soundproof aluminum alloy door and window. When using this device, first fix the window frame 1 in the preset installation position to ensure that it is stable and level. Then, install the window sash 2 inside the window frame 1 through the hinge component to ensure that the window sash 2 can be opened and closed flexibly.

[0045] The first glass 4, the second glass 5 and the fixed glass 3 are sequentially embedded inside the window sash 2 to form the first hollow cavity 6 and the second hollow cavity 7. Argon gas is then filled into the two hollow cavities. The low thermal conductivity of argon gas can effectively block heat transfer and improve the sound insulation effect.

[0046] When external noise travels to the doors and windows, it first comes into contact with the glass assembly consisting of fixed glass 3, second glass 5 and first glass 4. Because the surface of fixed glass 3 has a high density, when the sound hits the surface of fixed glass 3, some of the sound energy will be directly reflected back due to the obstruction of the surface of fixed glass 3 and cannot enter the room.

[0047] Furthermore, the unreflected sound penetrates the fixed glass 3 and enters the first hollow cavity 6. The argon gas filling the first hollow cavity 6 has a different acoustic impedance than both the glass and the air. At the interface between the glass and the argon gas, the sound is refracted and reflected, consuming some energy. Then the sound continues to propagate, penetrates the second glass 5, and enters the second hollow cavity 7. In the second hollow cavity 7, the sound is again refracted and reflected due to the presence of argon gas, further consuming energy.

[0048] After being weakened by the two hollow cavities, a small amount of sound still penetrates the first glass 4. At this time, the first sound insulation board 17 made of medium density fiber material in the mounting groove inside the window sash 2 plays a role. The porous structure of the medium density fiber material can absorb sound and further dissipate the remaining sound energy.

[0049] Then, fix the connecting strip 11 to one side of the window frame 1, insert the fixing block 13 into the fixing groove 12 of the connecting strip 11, so that the sealing frame 14 on one side of the fixing block 13 is initially positioned, and then tighten the bolt 16 through the threaded groove on the surface of the fixing block 13 and the connecting strip 11 to fix the sealing frame 14 to one side of the connecting strip 11.

[0050] Then, when the window sash 2 is closed, the sealing strip 15 is inserted into the interior of the sealing frame 14 to ensure the sealing between the window sash 2 and the window frame 1 when closed. In addition, together with the sealing layer 9 on one side of the fixed frame 8, multiple sealing defenses are formed to completely seal the gap between the window frame 1 and the window sash 2, preventing sound from entering the room through the gap.

[0051] If a very small amount of sound still passes through the window sash 2, the second sound insulation board 18 and sound insulation cotton 19 placed in the slot of the window frame 1 will undergo final sound insulation treatment. The sound absorption characteristics of the second sound insulation board 18 and sound insulation cotton 19 can absorb the residual sound, ensuring that the noise entering the room is reduced to the minimum, and further enhancing the sound insulation performance.

[0052] The procedure for using doors and windows is as follows: When opening doors and windows, hold handle 10 and apply force outward or inward around the hinge between window sash 2 and window frame 1 to open window sash 2, achieving functions such as ventilation. After use, hold handle 10 again and move window sash 2 towards window frame 1 until window sash 2 is tightly fitted against the sealing layer 9 on one side of fixed frame 8, and the sealing strip 15 is inserted into the interior of sealing frame 14 for tight contact, forming a seal, effectively blocking the entry of external sound and air. In addition, both window frame 1 and window sash 2 are made of aluminum alloy. The good rigidity of aluminum alloy itself ensures that window frame 1 and window sash 2 will not deform under stress during use, ensuring stable sound insulation effect.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
