[0002] Aluminum-clad wood energy-saving doors and windows are a type of composite door and window that combines the thermal insulation properties of wood with the corrosion resistance and high strength of aluminum alloy, making them excellent in terms of energy saving, sound insulation and decoration. They are made of wood as the base material and covered with an aluminum alloy frame through special processing.

[0003] However, aluminum-clad wood energy-saving doors and windows are too expensive, and wooden windows are prone to mold and termite infestation in humid environments, making them difficult to maintain and with a short service life. In response to this technical problem, this application proposes an aluminum-clad aluminum-plastic co-extruded composite profile snap-fit ​​structure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a snap-fit ​​structure for aluminum-clad aluminum-plastic co-extruded composite profiles. By wrapping a 3-6mm layer of micro-foamed hardened PVC skin around the outer wall of the aluminum liner, an aluminum-plastic co-extruded composite profile can be formed. The combination of nylon 66 thermal insulation strip and polyurethane foam can block heat conduction between the two aluminum liners. At the same time, the nylon 66 thermal insulation strip and polyurethane foam themselves also have good thermal insulation properties, which can significantly improve the energy-saving effect of the frame material.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A snap-fit ​​structure for an aluminum-clad aluminum-plastic co-extruded composite profile includes an aluminum liner and an aluminum profile. The outer walls of the two aluminum liners are fixedly connected with micro-foamed rigid PVC skin. The right end of the micro-foamed rigid PVC skin is fixedly connected with a snap-fit ​​body.

[0007] Furthermore, a PVDF alloy film is provided at the left end of the micro-foamed rigid PVC skin. The PVDF alloy film is used for decoration and to prevent external objects from directly contacting the micro-foamed rigid PVC skin.

[0008] Furthermore, each of the aluminum liners has two dovetail grooves at its outer end, and the outer walls of the dovetail grooves are filled with micro-foamed hardened PVC.

[0009] Furthermore, the buckle body is I-shaped, and the outer wall of the buckle body is engaged with the inner wall of the slot.

[0010] Furthermore, the nylon 66 thermal insulation strip is filled with polyurethane foam at one end, and the polyurethane foam is respectively disposed at the inward end of the aluminum liner at both ends.

[0011] This utility model has the following beneficial effects:

[0012] 1. In this utility model, by wrapping a 3-6mm layer of micro-foamed hardened PVC on the outer wall of the aluminum liner, an aluminum-plastic co-extruded composite profile can be formed. The combination of nylon 66 thermal insulation strip and polyurethane foam can block the heat conduction between the two aluminum liners. At the same time, nylon 66 thermal insulation strip and polyurethane foam themselves also have good thermal insulation performance, which can greatly improve the energy-saving effect of the frame material.

[0019] 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.

[0020] Reference Figure 1-3An embodiment of this utility model provides: an aluminum-clad aluminum-plastic co-extruded composite profile buckle structure, including an aluminum liner 1 and an aluminum profile 7. The outer walls of the two aluminum liners 1 are fixedly connected with micro-foamed hardened skin PVC2. The right end of the micro-foamed hardened skin PVC2 is fixedly connected with a buckle body 6. The left end of the aluminum profile 7 is provided with a buckle groove 9. The buckle body 6 is I-shaped. The outer wall of the buckle body 6 is snapped into the inner wall of the buckle groove 9. The two aluminum liners 1 are fixedly connected with nylon 66 heat insulation strips 4 at their inward ends. The inward ends of the nylon 66 heat insulation strips 4 are filled with polyurethane foam 5. The left and right ends of the polyurethane foam 5 are respectively set at the inward ends of the aluminum liners 1.

[0021] Specifically, firstly, two aluminum liners 1 are connected by nylon 66 thermal insulation strips 4. By wrapping a 3-6mm layer of micro-foamed hardened PVC skin 2 around the outer wall of the aluminum liners 1, an aluminum-plastic co-extruded composite profile can be formed. Next, polyurethane foam 5 is injected between the two nylon 66 thermal insulation strips 4, making the connection between the two aluminum liners 1 tighter. At the same time, the combination of nylon 66 thermal insulation strips 4 and polyurethane foam 5 can block heat conduction between the two aluminum liners 1. In addition, nylon 66 thermal insulation strips 4 and polyurethane foam 5 themselves also have good thermal insulation performance, which can significantly improve the energy-saving effect of the frame material. Finally, the aluminum profile 7 can be assembled on one side of the aluminum-plastic co-extruded composite profile by the snap-fit ​​body 6, so that the indoor aluminum-plastic co-extruded part and the outdoor aluminum alloy part can be produced separately, and can be replaced separately during maintenance to save maintenance costs.

[0022] Two dovetail grooves 8 are opened at the outer end of the aluminum liner 1. The outer wall of the dovetail groove 8 is filled with micro-foamed hardened skin PVC2. A PVDF alloy film 3 is set at the left end of the micro-foamed hardened skin PVC2. The PVDF alloy film 3 is used for decoration and to prevent external objects from directly contacting the micro-foamed hardened skin PVC2.

[0023] Specifically, the dovetail groove 8 opened on the aluminum liner 1 can increase its moment of inertia with a slight increase in the overall weight of the aluminum liner 1, thereby improving the overall wind pressure resistance and deformation capacity of the structure. The PVDF alloy film 3 sprayed on the surface of the micro-foamed hardened skin PVC2 can directly enrich the interior color, decorate the interior and protect the micro-foamed hardened skin PVC2, prevent indoor items from scratching the micro-foamed hardened skin PVC2 and causing damage, and extend the service life of the structure.

[0024] Working principle: In practical use, the micro-foamed rigid PVC2 is first installed in the designated position. Then, the aluminum profile 7 is clipped onto the buckle body 6 through the slot 9 on its surface. The aluminum profile 7 is installed on the micro-foamed rigid PVC2, so that the aluminum-plastic co-extruded composite profile formed by the micro-foamed rigid PVC2 and the aluminum liner 1 is located indoors. PVDF alloy film 3 is sprayed onto its surface using tools, which can enrich the interior color and prevent indoor items from scratching the micro-foamed rigid PVC2 and causing wear. The aluminum profile 7 is located outdoors and can be assembled, welded, and sprayed at high temperature, which is conducive to the overall installation of doors and windows. The two aluminum liners 1 inside the micro-foamed rigid PVC2 are separated by nylon 66 thermal insulation strip 4 and polyurethane foam 5, forming a thermally broken aluminum structure, which can significantly improve the thermal insulation performance of the component and achieve energy-saving effect. At the same time, the polyurethane foam 5 also has good sound insulation performance to ensure comfort during use.

[0025] 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.
