Abstract
Description
Technical Field
[0001] This utility model relates to the processing technology of aluminum-plastic co-extruded integrated screen window with flush inner and outer edges, and particularly to an aluminum-plastic co-extruded double pressure line installation component. Background Technology
[0002] In the field of building doors and windows, aluminum-plastic co-extruded doors and windows have become the preferred solution for energy-efficient buildings due to their combination of the high strength of aluminum alloy and the thermal insulation properties of plastic. With increasing demands for the aesthetics and energy efficiency of doors and windows, integrated windows with flush interior and exterior screens are becoming increasingly common. The installation process of the fixed glass directly affects the performance and installation efficiency of these doors and windows. Traditional single-sided pressure line installation methods are no longer sufficient to meet the installation needs of large window frames and small-sized glass. Therefore, developing a double-pressure line installation structure that balances ease of installation and energy efficiency has become a key direction for industry upgrading.
[0003] Existing aluminum-plastic co-extruded windows with integrated screens and flush interior / exterior surfaces generally use a single, extra-large interior pressure line to fix the glass. This method has significant drawbacks: Firstly, the extra-large interior pressure line requires customized production, and installation necessitates applying force from only one side of the interior. Limited operating space and uneven force distribution can easily lead to glass misalignment or pressure line deformation, especially in scenarios with large window frames and small glass panes, where installation difficulty increases exponentially. Secondly, a single pressure line prevents the glass and window frame from forming a continuous isothermal line, allowing heat to easily conduct through the gaps between the pressure line and the glass, resulting in decreased window insulation performance. For example, because the fixed glass is biased towards the exterior due to unilateral force application, heat generated by the temperature difference between the interior and exterior can easily penetrate through the connection gap between the pressure line and the window frame, increasing energy consumption and affecting indoor comfort. Furthermore, the uneven interior surface after traditional pressure line installation detracts from the overall aesthetics of the window. The complex installation, insufficient energy efficiency, and aesthetic defects of existing technologies can no longer meet the demands of modern buildings for high-performance windows. Structural innovation is urgently needed to achieve breakthroughs in both installation technology and performance. Utility Model Content
[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an aluminum-plastic co-extruded inner and outer double pressure line installation component. This component aims to solve the problems of difficult installation, uneven stress, and poor thermal insulation of existing double pressure line installation components with only one side pressure line, thereby improving installation efficiency and energy-saving performance of doors and windows.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] An aluminum-plastic co-extruded double-pressure line mounting component includes an outward-opening conversion frame. The top and bottom sides of the outward-opening conversion frame are fixedly connected to mounting brackets. A nylon 66 thermal insulation bridge is installed in the middle of the top mounting bracket. An inner pressure line is installed on the left end of the side opposite to the two mounting brackets, and an outer pressure line is installed on the right end of the side opposite to the two mounting brackets. A glossy fixed glass is provided between the inner and outer pressure lines.
[0007] Furthermore, an outward-opening fan is installed at the right end of the mounting bracket at the bottom, and a screen is installed at the left end of the mounting bracket at the bottom.
[0008] Furthermore, the top-mounted bright fixed glass and the Nylon 66 thermal insulation bridge are on an isotherm.
[0009] Furthermore, both the inner and outer crimping wires are made of aluminum alloy.
[0010] This utility model has the following beneficial effects:
[0011] 1. In this utility model, the traditional single indoor oversized pressure wire fixing is abandoned. Instead, an inner and outer pressure wire are used to fix the glass from both the indoor and outdoor sides. The inner pressure wire uses a standard specification, reducing installation difficulty and cost. The two work together to distribute the force, which can firmly fix the glass to the top and effectively prevent the glass from shifting in the large window frame. This not only facilitates the installation operation but also enhances the stability of the glass after installation.
[0012] 2. In this utility model, the double pressure line design places the fixed glass and the glass on the same isotherm, greatly reducing heat conduction. The outward-opening sash, outward-opening conversion frame, double pressure line, and thermal bridge work together to form a complete thermal insulation system, which can effectively block the exchange of heat between indoors and outdoors, significantly improve the thermal insulation performance of doors and windows, achieve energy saving and consumption reduction, and meet building energy conservation standards and people's needs for a comfortable living environment.

[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] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an aluminum-plastic co-extruded double-pressure line mounting component, including an outward-opening conversion frame 3. Mounting brackets are fixedly connected to the top and bottom sides of the outward-opening conversion frame 3. A nylon 66 thermal bridge 7 is installed in the middle of the top mounting bracket. Inner pressure lines 1 are installed on the left side of the two mounting brackets on opposite sides, and outer pressure lines 6 are installed on the right side of the two mounting brackets on opposite sides. A top-gloss fixed glass 2 is provided between the inner pressure lines 1 and the outer pressure lines 6. An outward-opening fan 4 is installed on the right side of the bottom mounting bracket, and a screen 5 is installed on the left side of the bottom mounting bracket. The top-gloss fixed glass 2 and the nylon 66 thermal bridge 7 are on the same isotherm. Both the inner pressure lines 1 and the outer pressure lines 6 are made of aluminum alloy.
[0019] Specifically, this aluminum-plastic co-extruded double-pressure line installation component has a clever working principle. The inner pressure line 1 and the outer pressure line 6 have clear division of labor. The inner pressure line is responsible for the indoor side, reducing installation difficulty and cost with standard specifications, while the outer pressure line is responsible for the outdoor side. Together, they fix the upper-pane fixed glass 2 from both the indoor and outdoor sides, changing the traditional single-indoor oversized pressure line fixing method. This disperses the force and effectively prevents the glass from shifting within the large window frame. The Nylon 66 thermal bridge 7 is the key to thermal insulation. The double pressure line design places the fixed glass and the glass on the same isotherm, significantly reducing heat conduction. The outward-opening sash 4, the outward-opening conversion frame 3, and the double pressure lines and thermal bridge work together to build a complete thermal insulation system, effectively blocking heat exchange between the indoor and outdoor areas, improving the thermal insulation performance of doors and windows, and achieving energy saving. In addition, the screen 5 can prevent mosquitoes and insects, and the outward-opening conversion frame is used to connect the outward-opening sash and other components. All components work together to ensure convenient glass installation while also ensuring the airtightness and watertightness of doors and windows.
[0020] Working Principle: The inner retaining line 1 and the outer retaining line 6 fix the glass from both the indoor and outdoor sides. The inner retaining line is responsible for fixing the glass on the indoor side, while the outer retaining line is responsible for fixing it on the outdoor side. This method changes the traditional method of relying solely on an extra-large indoor retaining line, distributing the fixing force. During installation, the inner retaining line uses standard specifications, reducing installation difficulty and cost. The outer retaining line works in conjunction with the inner retaining line, applying force from both sides to firmly fix the glass 2, preventing the glass from shifting in the large window frame. The Nylon 66 thermal bridge 7 is a key component for window and door insulation. The double retaining line design places the fixed glass and the thermal bridge on the same isotherm, reducing heat conduction. The outward-opening sash 4, the outward-opening conversion frame 3, and the double retaining lines and thermal bridge work together to form a complete insulation system, effectively blocking heat exchange between the indoor and outdoor areas, improving the thermal insulation performance of windows and doors, and achieving energy-saving effects. The screen 5 prevents mosquitoes from entering the room. The outward-opening conversion frame is used to connect components such as the outward-opening sash. All components work together to ensure the airtightness, watertightness, and thermal insulation performance of windows and doors while facilitating glass installation.
[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
