Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic co-extruded energy-saving doors and windows, and in particular to an integrated aluminum-plastic connector for a screen window with flush inner and outer surfaces. Background Technology

[0002] Aluminum-plastic co-extruded flush-fit screens are a high-performance, aesthetically pleasing, and practical type of screen. They combine the advantages of aluminum alloy and plastic using co-extruded aluminum-plastic profiles, possessing the high strength, corrosion resistance, and lightweight properties of aluminum alloy, while retaining the excellent thermal insulation, sound insulation, and heat insulation properties of plastic. After installation, the screen and window frame remain flush, presenting a clean and neat appearance from both inside and outside, greatly enhancing the overall aesthetics of the doors and windows. Furthermore, aluminum-plastic co-extruded flush-fit screens offer excellent sealing, effectively preventing insects and dust from entering the room. They are also easy to clean and maintain, and have a long service life, making them an ideal screen choice for modern home decoration.

[0003] The existing integrated aluminum-plastic co-extruded screen window with flush inner and outer surfaces is too expensive. This is because the complex profile structure leads to a complex production process, requiring extremely high precision in equipment and skilled workers. Furthermore, the use of special materials significantly increases raw material costs. The development of two sets of dedicated molds not only incurs huge financial costs but also places a heavy burden on subsequent mold maintenance and management. An unreasonable design of the solidified glass pressure line not only damages the overall aesthetics of the door and window but also weakens the sealing performance, affecting the user experience. The window installation process is even more challenging. The complex procedures not only rely on experienced technicians but are also frequently disrupted by variable environmental factors such as temperature, humidity, and available space, increasing construction risks and costs. To overcome these technical bottlenecks, this application proposes an integrated aluminum-plastic connector for flush inner and outer surfaces of the screen window. Through innovative structural design and material optimization, it aims to effectively reduce costs, simplify the process, and improve performance, promoting the widespread application of this type of product in the market. Therefore, this application proposes an integrated aluminum-plastic connector for flush inner and outer surfaces of the screen window to address these technical problems. Utility Model Content

[0017] 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.

[0018] Refer to Figure 1 andFigure 2 This utility model provides an embodiment of an integrated aluminum-plastic connector for a flush inner and outer screen window 3, comprising a window frame 1, an auxiliary frame 6 attached to the inner wall of the window frame 1 by means of thermally broken aluminum material, a thermal insulation strip 5 provided on the inner wall of the window frame 1, four inner frame sealing strips 7 provided on the inner wall of the auxiliary frame 6, a screen window pivot 4 provided on the inner wall of the window frame 1, a screen window 3 provided on the outer wall of the screen window pivot 4, a window sash 2 fixedly connected to the inner wall of the window frame 1, the inner frame sealing strips 7 being made from EPDM sealing strips, the screen window 3 being made from glass fiber yarn, and the thermal insulation strips 5 being made from nylon.

[0019] With increasingly stringent requirements for building energy conservation, the innovative design of aluminum-plastic co-extruded energy-saving window and door profiles has become a focus of the industry. This design uses thermally broken aluminum as its core material, deeply exploring its high strength and corrosion resistance, and achieving a balance between performance and cost through ingenious structural improvements. Traditional window and door profiles, in pursuit of flush interior and exterior surfaces and integrated screens, often require the development of complex cross-section profiles, leading to a significant increase in mold costs and processing difficulty. This innovation, however, adds a thermally broken aluminum subframe 6 within the aluminum-plastic co-extruded frame, breaking with conventional design thinking. By increasing the size of the nylon thermal insulation strip 5, it cleverly achieves flush interior and exterior surfaces and integrated screen 3.

[0020] This design does not require replacing the main materials of the original production line. By optimizing only the local structure, it can control costs while giving the doors and windows simple and smooth modern aesthetic lines, so that they can not only meet the functions, but also fit the current minimalist trend of architectural appearance design.

[0021] Structural stability is crucial for the long-term use of doors and windows. This innovation combines a nylon thermal break strip 5 with a cavity structure and a thermally broken aluminum subframe 6 to create a robust mechanical system. Traditional thermal break strips rely solely on planar contact with the subframe, making them prone to loosening under long-term wind pressure and temperature changes. The unique cavity structure of the new thermal break strip significantly increases the contact area with the subframe 6, acting like a custom-designed reinforced armor for the subframe. This structure not only enhances the friction between the thermal break strip and the subframe but also forms a three-dimensional support, ensuring the subframe remains stable even in complex environments. This effectively prevents problems such as decreased door and window sealing and difficulty in opening and closing due to subframe loosening, significantly extending the lifespan of doors and windows and reducing later maintenance costs. Optimized sealing performance is another major highlight of this design. The interior surface of the subframe 6 is precision milled to form stepped rubber grooves, which, together with four internal sealing strips 7, create a tight sealing barrier. These sealing strips are made of specially formulated and improved EPDM rubber, possessing excellent weather resistance and aging resistance, maintaining good elasticity even in extreme temperature environments. When doors and windows are closed, multiple sealing strips work together like a tightly interlocking toothed barrier, effectively isolating air and rainwater from the outside. This not only significantly reduces external noise interference indoors but also substantially reduces heat exchange between indoors and outdoors, providing strong support for building energy conservation and emission reduction.

[0022] In terms of the integration of appearance and function, multi-dimensional innovations have been made. The outdoor screen window 3 adopts a columnar hinge and a narrow screen sash design. After repeated optimization, the screen sash is finally completely flush with the window frame 1. This design not only makes the appearance of the door and window more integrated and modern, but also effectively solves the pain points of traditional protruding screen windows that are prone to dust accumulation and collisions. The screen window pivot 4 and the window sash 2 are firmly fixed to the inner wall of the window frame 1 with high-strength aluminum alloy rivets. The fiberglass screen window 3 can flexibly rotate and open and close around the screen window pivot 4. The fiberglass mesh is tough and durable and has good light transmission, which can meet the daily ventilation needs and effectively block the light.

[0023] Mosquitoes and other insects can enter the room. Meanwhile, the nylon thermal break strip 5, with its low thermal conductivity, forms a highly efficient insulation layer inside the window and door, acting like a solid insulation wall, achieving a perfect balance between functionality and aesthetics. This innovative design of aluminum-plastic co-extruded energy-saving window and door profiles fully considers the differentiated needs of the construction market for energy-saving windows and doors. Through structural optimization, material innovation, and process improvement, the overall performance of the windows and doors, including sound insulation and heat preservation, is enhanced while effectively improving the product's cost-effectiveness. Third-party testing shows that all performance indicators of these windows and doors meet the standards for energy-saving windows and doors used in home decoration, making them suitable for various residential and commercial buildings. This provides the home decoration energy-saving building market with a high-quality solution that combines practicality and economy, and is expected to drive the building window and door industry towards green and efficient development.

[0024] Working principle: The integrated aluminum-plastic connector of this flush-fitting screen window 3 achieves seamless integration of the inside and outside of the window with the screen window 3 without replacing the main material. Aesthetically, this is achieved by adding a thermally broken aluminum subframe 6 and an enlarged nylon thermal insulation strip 5. The exterior screen window 3 uses a columnar hinge with a narrow screen sash design, further enhancing the overall aesthetics. In terms of performance, the interior sealing strip groove of the subframe 6, combined with four internal sealing strips 7, forms four layers of seal, effectively preventing air and rainwater penetration and enhancing the overall window's airtightness. The nylon thermal insulation strip 5 reduces heat conduction and improves thermal insulation performance. The screen window 3, made of fiberglass yarn, combines ventilation and insect prevention. Regarding structural stability, the nylon thermal insulation strip 5 with a cavity structure is used in the thermally broken aluminum subframe 6 to strengthen the connection between the inside and outside of the subframe 6, ensuring the overall structure of the connector is sturdy and durable. With the above design, the connector not only meets the differentiated needs of energy-saving doors and windows in buildings and greatly improves the cost-effectiveness of energy-saving doors and windows with flush inner and outer screens, but also, as an innovative improvement in the processing technology of aluminum-plastic co-extruded energy-saving door and window profiles, further enhances the overall performance of doors and windows such as sound insulation and heat preservation, effectively reduces the heat conduction of the frame material, fully complies with the standards for energy-saving doors and windows in home decoration, and is easy to be widely used in the home decoration energy-saving building market.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still understand the technical solutions described in the foregoing embodiments.
