Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy door and window technology, and in particular to a seamless welded thermally broken aluminum alloy door and window with heat insulation and noise reduction. Background Technology

[0002] Seamless welded thermally broken aluminum alloy doors and windows are an upgraded product of traditional thermally broken aluminum alloy doors and windows. Through seamless welding process, gaps at the joints of the profiles are eliminated, while retaining the thermal insulation advantages of the thermally broken structure. Significant improvements are achieved in terms of sealing, aesthetics, and durability, making it one of the mainstream choices in the high-end door and window market.

[0003] For example, a seamless welded thermally broken aluminum profile with announcement number "CN214303562U" has a second inlay groove and a first inlay groove respectively in the middle part of the inner frame and outer frame of the aluminum profile. The second and first inlay grooves are internally connected and their shapes are the same as the thermal insulation liner. First locking teeth are provided on both sides of the thermal insulation liner, and second locking teeth are provided on the inner sidewalls of the second and first inlay grooves. The thermal insulation liner is installed inside the second and first inlay grooves by inlaying, and the first and second locking teeth are locked together, facilitating installation and disassembly and improving the stability of the connection between the inner and outer frames of the aluminum profile. However, in the above structure, the contact surface between the first and second locking teeth is a rigid contact. With long-term use, temperature changes and vibrations can easily cause the gap to increase, thus reducing the thermal insulation effect. Furthermore, in the above structure, the aluminum alloy inner and outer frames are themselves rigid materials, which easily transmit sound waves, allowing noise to easily enter the room and failing to effectively isolate noise. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing a seamless welded thermally broken aluminum alloy door and window with heat insulation and noise reduction. The rubber pad can reduce the gaps on the contact surface, thereby improving the heat insulation effect. By filling the first and third cavities with sound insulation material, the noise can be effectively isolated.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This seamless welded thermally broken aluminum alloy door and window with heat insulation and noise reduction includes an aluminum alloy inner frame and an aluminum alloy outer frame. The outer wall of the aluminum alloy inner frame is welded to the aluminum alloy outer frame. The inner walls of both the aluminum alloy outer frame and the aluminum alloy inner frame are fixedly connected with second locking teeth. The aluminum alloy outer frame and the aluminum alloy inner frame are provided with an installation structure. Multiple pieces of glass are installed on the inner wall of the aluminum alloy inner frame. The aluminum alloy outer frame and the aluminum alloy inner frame are provided with a filling box. The filling box is provided with a barrier structure. Heat insulation plates are fixedly connected to both sides of the filling box.

[0006] To further improve the design, a sealing door is installed on the outside of the filling box.

[0007] Further improvements include the installation structure comprising a U-shaped elastic sheet, the outer wall of which is fixedly connected to the second locking tooth, and a rubber pad fixedly connected to the inner wall of which the inner side of the rubber pad is pressed against the first locking tooth.

[0008] Further improvements include fixing the outer walls of the first tooth to the heat insulation liner.

[0009] In a further improvement, the barrier structure includes vertical plates, the outer walls of which are fixedly connected to the filling box. A first cavity is formed between the front vertical plate and the filling box, a second cavity is formed between adjacent vertical plates, and a third cavity is formed between the rear vertical plate and the filling box.

[0010] The beneficial effects of this utility model are as follows: In this utility model, through the cooperation of the second locking tooth and the mounting structure, the first locking tooth is inserted into the second locking tooth, and the outer side of the first locking tooth is pressed against the rubber pad. The U-shaped elastic sheet always applies elastic force, so that the rubber pad is pressed against the first locking tooth, reducing the occurrence of gaps, and to a certain extent, the heat insulation effect can be improved.

[0011] By combining the filling box and the barrier structure, the first and third cavities are filled with sound insulation materials, such as glass wool, centrifugal wool, and sound insulation cotton. Their porous structure absorbs sound wave energy and reduces noise entering the room, which can effectively isolate noise. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] See attached document Figure 1-5 In this embodiment, a seamless welded thermally broken aluminum alloy door and window with heat insulation and noise reduction includes an aluminum alloy inner frame 1 and an aluminum alloy outer frame 2. The outer wall of the aluminum alloy inner frame 1 is welded to the aluminum alloy outer frame 2. The outer wall of the aluminum alloy inner frame 1 and the aluminum alloy outer frame are welded by a seamless welding process. The inner walls of the aluminum alloy outer frame 2 and the aluminum alloy inner frame 1 are both fixedly connected with second locking teeth 10. The aluminum alloy outer frame 2 and the aluminum alloy inner frame 1 are provided with an installation structure 5. Multiple glass panes 3 are installed on the inner wall of the aluminum alloy inner frame 1. The aluminum alloy outer frame 2 and the aluminum alloy inner frame 1 are provided with a filling box 7. The filling box 7 is provided with a barrier structure 8. Heat insulation lining plates 6 are fixedly connected to both sides of the filling box 7. A sealing door 9 is installed on the outside of the filling box 7.

[0020] The mounting structure 5 includes a U-shaped elastic sheet 501. The outer wall of the U-shaped elastic sheet 501 is fixedly connected to the second locking tooth 10. A rubber pad 502 is fixedly connected to the inner wall of the U-shaped elastic sheet 501. The inner side of the rubber pad 502 is pressed against the first locking tooth 4. The outer wall of the first locking tooth 4 is fixedly connected to the heat insulation liner 6. The heat insulation liner is made of PA66+GF, which has excellent heat insulation performance (low thermal conductivity), high strength (can withstand the stress of thermal expansion and contraction of aluminum profiles), and weather resistance.

[0021] The barrier structure 8 includes vertical plates 801. The outer walls of multiple vertical plates 801 are fixedly connected to the filling box 7. A first cavity 802 is formed between the front vertical plate 801 and the filling box 7. A second cavity 803 is formed between adjacent vertical plates 801. A third cavity 804 is formed between the rear vertical plate 801 and the filling box 7. The first cavity 802 and the third cavity 804 are filled with sound insulation materials, such as glass wool, centrifugal wool, and sound insulation cotton, which absorb sound wave energy through their porous structure. The second cavity 803 is filled with heat insulation materials, such as polyurethane foam, which can effectively block air convection and play a role in heat insulation.

[0022] Working principle:

[0023] When using seamless welded thermally broken aluminum alloy doors and windows with thermal insulation and noise reduction:

[0024] The heat insulation liner 6 is inserted into the aluminum alloy inner frame 1 and the aluminum alloy outer frame 2. At this time, the first locking tooth 4 is inserted into the second locking tooth 10, and the outer side of the first locking tooth 4 is pressed against the rubber pad 502. The U-shaped elastic sheet 501 always applies elastic force to make the rubber pad 502 press against the first locking tooth 4, reducing the occurrence of gaps. To a certain extent, this can improve the heat insulation effect. At the same time, the second cavity 803 is filled with heat insulation material, such as polyurethane foam, which can effectively block air convection and play a role in heat insulation.

[0025] The first cavity 802 and the third cavity 804 are filled with sound insulation materials, such as glass wool, centrifugal wool, and sound insulation cotton. Their porous structure absorbs sound wave energy and reduces noise entering the room, which can effectively isolate noise and achieve the purpose of noise reduction.

[0026] Then, the sealing door 9 is installed, and the aluminum alloy inner frame 1 and aluminum alloy outer frame 2 are welded together using a seamless welding process. Finally, the aluminum alloy outer frame 2 is installed in the designated position, which can play the role of sealing the space, while also helping to enhance the overall heat insulation and windproof performance.

[0027] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
