[0014] 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.

[0015] Reference Figures 1 to 4 One embodiment provided by this utility model: A modular aluminum alloy door and window includes a window sill, a frame 1 embedded in the window sill, and mounting fasteners disposed between the window sill and the frame 1. The mounting fasteners are arranged vertically and symmetrically on the left and right sides of the frame 1. The cross-section of the mounting fasteners is an F-shaped structure, including a receiving cavity with an opening facing forward, a pressing plate 2 that abuts against the left and right sides of the frame 1, a stop plate 3 that abuts against the rear side of the frame 1, and a fixing plate 4 that abuts against the left and right sides of the window sill. The fixing plate 4 is connected to the window sill by bolts. The receiving cavity is provided with a plurality of snap-fit ​​components 5. The snap-fit ​​components 5 are movable and telescopic and can extend horizontally through the pressing plate 2. The left and right sides of the frame 1 are provided with snap-fit ​​grooves 6 that match the snap-fit ​​components 5. The pressing plate 2 is connected to the frame 1 through the snap-fit ​​components 5.

[0016] The windowsill, a square-hole structure, is installed in the wall for mounting aluminum alloy doors and windows. The aluminum alloy doors and windows consist of a frame 1 and a window sash. The frame 1 is a square frame structure, fitted inside the windowsill and positioned around its perimeter. The window sash is openable and installed inside the frame 1. Mounting fasteners are located between the windowsill and the frame 1, arranged vertically. Two mounting fasteners are symmetrically positioned on the left and right sides of the frame 1, with one side connecting to the windowsill and the other side connecting to the frame 1.

[0017] The assembly fastener has an F-shaped cross-section, including horizontally spaced pressing plates 2 and fixing plates 4, and a stop plate 3 connected to the rear of the pressing plates 2 and fixing plates 4. The pressing plates 2 abut against the left and right sides of the frame 1 and are connected by snap-fit ​​components 5. The fixing plates 4 abut against the left and right sides of the windowsill and are connected by bolts. The stop plate 3 abuts against the rear of the frame 1. A receiving cavity is located between the pressing plates 2 and fixing plates 4, with an opening facing forward. It houses several snap-fit ​​components 5, which are evenly distributed and spaced along the vertical direction. The snap-fit ​​components 5 are telescopically movable; one end of each component is located within the receiving cavity, and the other end can extend horizontally through the pressing plates 2. Snap-fit ​​slots 6 are located on the left and right sides of the frame 1, matching and corresponding to the snap-fit ​​components 5. After extending outward from the pressing plates 2, the snap-fit ​​components 5 can be inserted into the snap-fit ​​slots 6 and engage with them. The pressing plates 2 are connected to the frame 1 through the snap-fit ​​components 5.

[0018] By setting up mounting hardware, when installing aluminum alloy doors and windows, first, two mounting hardwares are placed upright, abutting against the left and right sides of the window sill respectively. The fixing plate 4 is connected to the window sill with bolts to fix the window sill to the mounting hardware. Then, the frame 1 is inserted between the two mounting hardwares, with the left and right sides of the frame 1 abutting against the pressing plate 2 respectively. The frame 1 is pushed backward until the rear side of the frame 1 abuts against the stop plate 3, thus limiting the position of the frame 1. Finally, the snap-fit ​​component 5 extends through the pressing plate 2 and inserts into the snap-fit ​​grooves 6 on the left and right sides of the frame 1, snapping with the grooves 6 to fix the frame 1 to the mounting hardware. Using the above installation method, the frame 1 and the mounting hardware fit more closely, improving the sealing between them and preventing ventilation leaks. Moreover, installation and disassembly are more convenient, and the aluminum alloy doors and windows can be reused after disassembly.

[0019] In this embodiment, preferably, the snap-fit ​​assembly 5 includes snap-fit ​​blocks 7 extending to both sides of the frame 1, and the pressing plate 2 is provided with through holes 8 that match the snap-fit ​​blocks 7. The snap-fit ​​blocks 7 are inserted into the through holes 8 and are horizontally slidably connected to the through holes 8.

[0020] The snap-fit ​​block 7 is located within the receiving cavity and extends towards both sides of the frame 1, allowing for horizontal movement and extension. The through hole 8, located on the pressing plate 2, is a through-hole structure that matches and corresponds to the snap-fit ​​block 7. The snap-fit ​​block 7 is inserted into the through hole 8 and horizontally slidably connected to it, extending outwards through the through hole 8 until it engages with the snap-fit ​​groove 6. Initially, the snap-fit ​​block 7 retracts into the receiving cavity to avoid affecting the installation of the frame 1. After the frame 1 is positioned, the snap-fit ​​block 7 is driven to extend outwards, passing through the pressing plate 2 into the snap-fit ​​groove 6 and engaging with it to achieve the assembly function.

[0021] In this embodiment, preferably, the snap-fit ​​block 7 includes a limiting part 9 located in the accommodating cavity and a guide part 10 extending outward relative to the pressing plate 2. The limiting part 9 is in movable contact with the pressing plate 2, and the guide part 10 is matched with the snap-fit ​​groove 6.

[0022] One end of the snap-fit ​​block 7 is a limiting part 9, located inside the receiving cavity. The size of the limiting part 9 is larger than the size of the through hole 8, allowing it to move and abut against the pressing plate 2, thus limiting the travel of the snap-fit ​​block 7. The other end of the snap-fit ​​block 7 is a guide part 10, which is matched with the snap-fit ​​groove 6 and can extend outward relative to the pressing plate 2. After the frame 1 is limited, the snap-fit ​​block 7 is driven to extend outward, and the guide part 10 passes through the pressing plate 2 and enters the snap-fit ​​groove 6 until the limiting part 9 abuts against the pressing plate 2. The guide part 10 and the snap-fit ​​groove 6 are then engaged, improving assembly accuracy.

[0023] In this embodiment, preferably, the guide portion 10 includes an inclined surface 11 that is disposed opposite to the stop plate 3, and the snap-fit ​​groove 6 is provided with a guide sliding portion 12 that matches the inclined surface 11. The guide portion 10 is slidably connected to the guide sliding portion 12 through the inclined surface 11.

[0024] The inclined surface 11 is located on one side of the guide portion 10, facing the stop plate 3, and inclined from the rear side of the guide portion 10 to the front side of the guide portion 10. The guide sliding portion 12 is located in the snap-fit ​​groove 6, matching the inclined surface 11, and has the same slope as the inclined surface 11. The guide portion 10 is slidably connected to the guide sliding portion 12 through the inclined surface 11. After the frame 1 is limited, the drive snap-fit ​​block 7 extends outward, and the guide portion 10 passes through the pressing plate 2 and enters the snap-fit ​​groove 6. The inclined surface 11 of the guide portion 10 abuts against the guide sliding portion 12 of the snap-fit ​​groove 6, and the two are slidably connected until the limiting portion 9 abuts against the pressing plate 2, and the guide portion 10 snaps into the snap-fit ​​groove 6. During this process, through the cooperation of the inclined surface 11 and the guide sliding portion 12, the horizontal force of the snap-fit ​​block 7 can be converted into the vertical force of the frame 1, thereby pushing the frame 1 to move backward and pressing the stop plate 3, improving the sealing performance.

[0025] In this embodiment, preferably, a number of snap-fit ​​components 5 are evenly distributed and spaced along the direction of the pressing plate 2, and rubber pads are respectively provided between the stop plate 3, the pressing plate 2 and the frame 1.

[0026] Several snap-fit ​​components 5 are evenly distributed and spaced along the direction of the pressing plate 2, making the force on the frame 1 more balanced and the connection more stable. The rubber pad is located between the stop plate 3 and the frame 1, and between the pressing plate 2 and the frame 1. The rubber pad extends vertically along the direction of the stop plate 3 and the pressing plate 2, and is installed to match the frame 1. Based on the elastic material properties, it can improve the sealing of the connection and avoid assembly gaps.

[0027] In this embodiment, preferably, a rotatable screw 13 is provided in the accommodating cavity. The screw 13 is arranged in a horizontal direction. The snap-fit ​​block 7 is sleeved on the outside of the screw 13. One end of the screw 13 is connected to the snap-fit ​​block 7 in a transmission manner, and the other end of the screw 13 is rotatably connected to the fixing plate 4.

[0028] The screw 13 is located inside the accommodating cavity and is rotatable, extending horizontally. A dial is sleeved on the outside of the screw 13, and the dial is coaxially connected to the screw 13. The screw 13 can be rotated by rotating the dial. The locking block 7 has a screw hole for inserting the screw 13, and the screw hole has an internal thread that matches the screw 13. The locking block 7 is sleeved on the outside of the screw 13 through the screw hole. One end of the screw 13 is drivenly connected to the locking block 7, and the other end of the screw 13 is rotatably connected to the fixing plate 4. After the frame 1 is in position, rotating the dial drives the screw 13 to rotate, and the screw 13 is drivenly connected to the locking block 7, thereby driving the locking block 7 to extend outward and engage with the locking groove 6, realizing the movable telescopic function.

[0029] In this embodiment, preferably, a U-shaped plate 14 connected to the pressing plate 2 is provided in the accommodating cavity, the snap-fit ​​block 7 is located inside the U-shaped plate 14 and is slidably connected to the U-shaped plate 14, and the screw 13 passes through the U-shaped plate 14 and is connected to the snap-fit ​​block 7 in a transmission manner.

[0030] The U-shaped plate 14 is located inside the accommodating cavity and has a U-shaped structure. Its opening faces the snap-fit ​​block 7 and is connected to the pressing plate 2. The snap-fit ​​block 7 is positioned relative to the inner side of the U-shaped plate 14. During the extension and retraction of the snap-fit ​​block 7, the outer side of the snap-fit ​​block 7 is slidably connected to the inner side of the U-shaped plate 14, and the end of the snap-fit ​​block 7 away from the frame 1 is movably abutting against the end of the U-shaped plate 14. The U-shaped plate 14 has a through hole for inserting a screw 13, which passes through the through hole and is driven to the snap-fit ​​block 7. After the frame 1 is positioned, the screw 13 is driven to the snap-fit ​​block 7, thereby driving the snap-fit ​​block 7 to extend outward. During this process, the U-shaped plate 14 and the snap-fit ​​block 7 are slidably connected, thereby improving the stability of the movement and providing a stroke limit function when the snap-fit ​​block 7 retracts and resets.

[0031] The above are merely preferred embodiments of the present utility model and are 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.
