[0034] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention.

[0035] The present invention also has the following implementation modes based on the above:

[0036] In a further embodiment of the utility model, the processing technology is as follows: first, the aluminum alloy profile 1 and the UPVC plastic profile 2 are seamlessly welded into a whole frame, and then the aluminum alloy profile 1 and the UPVC plastic profile 2 are assembled through the mortise and tenon structure formed by the aluminum alloy profile tenon 101 and the UPVC plastic profile tenon groove 201. The assembly process is simple and convenient, the fastening is strong after assembly, and the indoor and outdoor appearance is good.

[0037] In a further embodiment of the utility model, the structural features are as follows: the connection part of the aluminum alloy profile tenon 101 and the UPVC plastic profile tenon groove 201 adopts an interference fit, the UPVC plastic profile 2 has a certain elastic deformation ability and the material strength is less than the aluminum alloy profile 1, and after the aluminum alloy profile tenon 101 is clamped into the UPVC plastic profile tenon groove 201 by external force, the tenon connection can be smoothly achieved. Due to the seamless welding characteristics of the entire frame of the aluminum alloy profile 1 and the UPVC plastic profile 2, it is impossible to dismantle it non-destructively later, ensuring that the structure is tight and firm.

[0038] In a further embodiment of the present invention, the UPVC plastic profile 2 is provided with a sash glass and is pressed by the aluminum alloy profile 1. Figure 4 As shown, the periphery of the sash glass is filled with two-component glue for support and sealing, an inner sash glass pad is provided between the indoor side of the sash glass and the UPVC plastic profile 2 to avoid direct contact between the sash glass and the UPVC plastic profile 2, an outer sash glass adhesive strip is installed on the aluminum alloy profile 1, and the outer sash glass adhesive strip presses the outdoor side of the sash glass to achieve sealing between the sash glass and the aluminum alloy profile 1, and at the same time, by pressing the sash glass, the inner sash glass pad is compressed to achieve sealing between the sash glass and the UPVC plastic profile 2.

[0039] In a further embodiment of the utility model, the outer periphery of the UPVC plastic profile 2 is further provided with an installation groove for installing a sealing strip, and the sealing performance of the window sash and the window frame is ensured by assembling two sealing strips on the UPVC plastic profile 2.

[0040] In a further embodiment of the utility model, the inner peripheral groove side panel 2011 located on the top side of the UPVC plastic profile 2 is inclined toward the outer peripheral groove side panel 2012 located on the top side of the UPVC plastic profile 2, the inner peripheral groove side panel 2011 located on the bottom side of the UPVC plastic profile 2 is inclined toward the outer peripheral groove side panel 2012 located on the bottom side of the UPVC plastic profile 2, the inner peripheral groove side panel 2011 located on the left side of the UPVC plastic profile 2 is inclined toward the outer peripheral groove side panel 2012 located on the left side of the UPVC plastic profile 2, and the inner peripheral groove side panel 2011 located on the right side of the UPVC plastic profile 2 is inclined toward the outer peripheral groove side panel 2012 located on the right side of the UPVC plastic profile 2.

[0041] In a further embodiment of the utility model, by connecting the aluminum alloy profile 1 and the UPVC plastic profile 2 by snapping, the thickness of the aluminum-coated plastic window sash can be greatly reduced, making it easier to install a window screen between the window frame and the window sash. Figure 4 As shown, the window screen and the window sash are both opened toward the indoor side.

[0042] In a further embodiment of the utility model, during the assembly process of the aluminum alloy profile 1 and the UPVC plastic profile 2, after the aluminum alloy profile tenon 101 is aligned with the UPVC plastic profile tenon groove 201, an external force is applied to the aluminum alloy profile 1 to clamp the aluminum alloy profile tenon 101 into the UPVC plastic profile tenon groove 201. The UPVC plastic profile tenon groove 201 returns to its original state after a brief elastic deformation, thereby clamping the aluminum alloy profile 1. The connection strength is high, the assembly is easy, the subsequent non-destructive disassembly is impossible, and the safety performance is high.

[0043] In a further embodiment of the utility model, the aluminum alloy profile 1 and the UPVC plastic profile 2 are seamlessly welded as a whole frame. After the glass is installed, the aluminum alloy profile 1 and the UPVC plastic profile 2 are tightly connected as a whole through a tenon structure.

[0044] In a further embodiment of the utility model, the aluminum alloy profile tenon 101 and the UPVC plastic profile tenon 201 are connected by interference fit, utilizing the characteristics of aluminum alloy hardness being greater than UPVC hardness and UPVC elastic deformation. After the aluminum alloy profile tenon 101 is clamped into the UPVC plastic profile tenon 201 by external force, due to the seamless welding characteristics of the entire frame of the aluminum alloy profile 1 and the UPVC plastic profile 2, it is impossible to remove it non-destructively afterwards, thereby ensuring that the structure is tight and firm.

[0045] In a further embodiment of the present invention, the aluminum alloy profile 1 and the UPVC plastic profile 2 are pressed and clamped together. Figure 1 As shown, the limiting end 1011 abuts against the peripheral notch side plate 2012, and the pressing depth of the limiting end 1011 is limited by the peripheral notch side plate 2012 to prevent the limiting end 1011 from being pressed too deep, continuously applying pressure to the sash glass, and causing the sash glass to break.

[0046] In a further embodiment of the present invention, the inner notch side plate 2011 and the hook-shaped structure 2014 are as follows Figure 1 and Figure 3 As shown, the clamping end 1012 is as shown in Figure 1 and Figure 2 As shown, during the crimping process, the clamping end 1012 is aligned with the notch of the UPVC plastic profile mortise 201 and pressed inwardly into the aluminum alloy profile 1. The hook-shaped structure 2014 is pushed by the clamping end 1012, and the inner circumferential notch side plate 2011 is deflected and deformed inwardly. When the hook-shaped structure 2014 is clamped into the clamping limit groove 1013, the inner circumferential notch side plate 2011 rebounds to its original position.

[0047] In a further embodiment of the utility model, the length of the clamping end 1012 is longer, the aluminum alloy material is not easy to deform, the length of the inner groove side plate 2011 is shorter, the UPVC material is elastic, and shortening the length of the inner groove side plate 2011 can effectively reduce the elastic deformation of the inner groove side plate 2011, thereby ensuring that the structure is tight and firm.

[0048] In a further embodiment of the utility model, the outer peripheral surface of the hook-shaped structure 2014 is inclined to facilitate the pushing in of the tenon 101 of the aluminum alloy profile, and the inner peripheral groove side panel 2011 is inclined toward the outer periphery. The inclined design improves the connection strength between the inner peripheral groove side panel 2011 and the indoor inner groove bottom panel 2013, thereby avoiding the inner peripheral groove side panel 2011 from breaking toward the inner periphery during the pressing process of the aluminum alloy profile 1.

[0049] In a further embodiment of the utility model, the top ends of the two limiting ends 1011 located on the left and right sides of the aluminum alloy profile 1 are respectively connected to the left and right ends of the limiting end 1011 located on the top side of the aluminum alloy profile 1, and the bottom ends of the two limiting ends 1011 located on the left and right sides of the aluminum alloy profile 1 are respectively connected to the left and right ends of the limiting end 1011 located on the bottom side of the aluminum alloy profile 1.

[0050] In a further embodiment of the utility model, the top ends of the two clamping ends 1012 located on the left and right sides of the aluminum alloy profile 1 are respectively connected to the left and right ends of the clamping end 1012 located on the top side of the aluminum alloy profile 1, and the bottom ends of the two clamping ends 1012 located on the left and right sides of the aluminum alloy profile 1 are respectively connected to the left and right ends of the clamping end 1012 located on the bottom side of the aluminum alloy profile 1.

[0051] In a further embodiment of the utility model, the top ends of the two peripheral groove side panels 2012 located on the left and right sides of the UPVC plastic profile 2 are respectively connected to the left and right ends of the peripheral groove side panels 2012 located on the top side of the UPVC plastic profile 2, and the bottom ends of the two peripheral groove side panels 2012 located on the left and right sides of the UPVC plastic profile 2 are respectively connected to the left and right ends of the peripheral groove side panels 2012 located on the bottom side of the UPVC plastic profile 2.

[0052] In a further embodiment of the utility model, the top ends of the two indoor side groove bottom plates 2013 located on the left and right sides of the UPVC plastic profile 2 are respectively connected to the left and right ends of the indoor side groove bottom plates 2013 located on the top side of the UPVC plastic profile 2, and the bottom ends of the two indoor side groove bottom plates 2013 located on the left and right sides of the UPVC plastic profile 2 are respectively connected to the left and right ends of the indoor side groove bottom plates 2013 located on the bottom side of the UPVC plastic profile 2.

[0053] In a further embodiment of the utility model, the top ends of the two inner circumferential groove side panels 2011 located on the left and right sides of the UPVC plastic profile 2 are respectively provided with seams on the left and right ends of the inner circumferential groove side panels 2011 located on the top side of the UPVC plastic profile 2, and the bottom ends of the two inner circumferential groove side panels 2011 located on the left and right sides of the UPVC plastic profile 2 are respectively provided with seams on the left and right ends of the inner circumferential groove side panels 2011 located on the bottom side of the UPVC plastic profile 2. By designing the inner circumferential groove side panels 2011 with reserved seams at the corners, it is convenient to ensure that the inner circumferential groove side panels 2011 can undergo elastic deformation and will not be damaged after rebound during the assembly process of the aluminum alloy profile 1.

[0054] In a further embodiment of the utility model, the structure is different from the general non-welded aluminum alloy composite plastic window or the broken bridge aluminum alloy window structure. It adopts the research and development thinking of the aluminum-clad wood window system, and the aluminum alloy profile and the UPVC profile are cut, processed and welded as a whole frame separately, and the aluminum alloy plate frame and the UPVC whole frame are composited in the form of a buckle. The consistency of the whole window is stronger than that of the traditional plastic window, and the thermal insulation performance of the whole window is better than that of the traditional aluminum alloy window. The main UPVC profile meets the Class A standard in GB / T8814, uses high-quality UPVC particles as raw materials, does not add recycled materials, and can be coated on the indoor side to provide more options.

[0055] In a further embodiment of the utility model, the structure redesigns the combination of the aluminum alloy profile and the UPVC profile of the aluminum-coated plastic window sash, keeps the UPVC profile as the basis of the main load-bearing component unchanged, and adjusts the combination of the aluminum alloy double-cantilever hook coated UPVC to be connected to the UPVC profile slot through the single cantilever tenon of the aluminum alloy profile. Because the single cantilever tenon structure is adopted, the aluminum alloy profile can be welded as a whole frame, and the whole frame can be connected to the UPVC frame by properly processing the corner position without affecting the integrity of the structure. The tenon connection process can be implemented after the glass is installed, and the sash can be installed on the outside of the glass room to ensure the integrated and non-pressure strip look on the indoor side. Since the material that produces deformation in the process of this structure is UPVC material with good elasticity, almost no irreversible damage will be caused to any material in the structure during the installation process.

[0056] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
