[0026] 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.

[0027] This utility model provides, for example Figures 1-5 The attached frame of an aluminum alloy door and window shown includes a horizontal frame 1 and a vertical frame 2. Two horizontal frames 1 and two vertical frames 2 are provided. Each end of the vertical frame 2 has a first inclined surface, and each end of the horizontal frame 1 has a second inclined surface. A first sealing gasket 3 is fixedly provided on the side of the first inclined surface, and a second sealing gasket 4 is fixedly provided on the side of the second inclined surface. The first sealing gasket 3 and the second sealing gasket 4 are in contact with each other. A snap-fit ​​assembly is provided between the horizontal frame 1 and the vertical frame 2. The snap-fit ​​assembly includes a triangular slot and a rectangular slot fixedly provided at the end of the horizontal frame 1, which are interconnected. A protrusion 5 is fixedly provided at the end of the vertical frame 2, and a rectangular block 6 is fixedly provided on the side of the protrusion 5. The protrusion 5 and the triangular slot are interlocked, and the rectangular block 6 and the rectangular slot are interlocked. A locking assembly is provided at the end of the horizontal frame 1.

[0028] The locking assembly includes a limiting groove 7 fixedly installed inside the horizontal frame 1, a limiting plate 8 slidably installed inside the limiting groove 7, an insert rod 9 fixedly installed at the end of the limiting plate 8, the insert rod 9 movably extending into the interior of the triangular slot, a fixing groove 10 opened inside the protrusion 5, the insert rod 9 movably extending into the interior of the fixing groove 10, a first spring 12 fixedly connected between the ends of the limiting plate 8 and the limiting groove 7, and the end of the insert rod 9 is set as a bevel structure.

[0029] Specifically, in the process of using this utility model, the protrusion 5 and rectangular block 6 on the vertical frame 2 are respectively inserted into the triangular slot and the rectangular slot. During the insertion process, the inclined structure on the insertion rod 9 causes the rectangular block 6 to push the insertion rod 9 and the limiting plate 8 into the limiting groove 7, allowing the rectangular block 6 to be smoothly inserted into the rectangular slot. At this time, the insertion rod 9 and the fixing groove 10 are in opposite positions, and the first spring 12 restores its elasticity, driving the insertion rod 9 into the fixing groove 10, quickly completing the snap-fit ​​fixing of the horizontal frame 1 and the vertical frame 2. Through this assembly method, the problem of the existing aluminum alloy door and window subframes being welded together, requiring specific transport vehicles and thus being troublesome during handling or transportation, is solved.

[0030] In addition, by setting the first sealing gasket 3 and the second sealing gasket 4, the airtightness of the connection between the horizontal frame 1 and the vertical frame 2 is improved, preventing external moisture from entering the room through the connection between the horizontal frame 1 and the vertical frame 2.

[0031] When it is necessary to disassemble this subframe, since the side of the limiting plate 8 is fixedly provided with a push rod 11, the end of the push rod 11 extends movably out of the horizontal frame 1 near the indoor side, and the horizontal frame 1 is provided with a sliding groove for the push rod 11 to slide. The limiting groove 7 and the sliding groove are connected to each other, and the distance between the upper and lower surfaces of the limiting groove 7 is greater than the distance between the upper and lower surfaces of the sliding groove. Pulling the push rod 11 will drive the limiting plate 8 and the insert rod 9 to move, allowing the insert rod 9 to disengage from the fixed groove 10, so that the horizontal frame 1 and the vertical frame 2 can be disassembled, improving the convenience of the device.

[0032] Furthermore, a first folding plate 13 is fixedly installed on the side of the horizontal frame 1, and a second folding plate 14 is fixedly installed on the side of the vertical frame 2. After the subframe is assembled, the subframe and the window on the wall are bonded together with expanding foam. The first folding plate 13 and the second folding plate 14 increase the contact area between the expanding foam and the subframe, thereby improving the stability of the subframe bonding.

[0033] To prevent the expansion foam from leaking, a first sleeve plate 15 is fixedly installed at both ends of the side of the horizontal frame 1. A first movable plate 16 is slidably installed inside the first sleeve plate 15. A number of second springs 17 are fixedly connected between the end of the first movable plate 16 inside the first sleeve plate 15 and the inner wall of the first sleeve plate 15. A first folding plate 13 is located between the two first sleeve plates 15. At the same time, a second sleeve plate 18 is fixedly installed at both ends of the side of the vertical frame 2. A second movable plate 19 is slidably installed inside the second sleeve plate 18. A number of third springs are fixedly connected between the end of the second movable plate 19 inside the second sleeve plate 18 and the inner wall of the second sleeve plate 18. A second folding plate 14 is located between the two second sleeve plates 18.

[0034] Taking the horizontal frame 1 as an example, the first movable plate 16 and the second spring 17 are set so that the first movable plate 16 fits tightly against the window on the wall, and the foam is confined between the two first plates 15, thereby avoiding the side leakage of the foam and improving the practicality of the device.

[0035] Furthermore, the second plate 18 extends to the end of the vertical frame 2, and the end of the first plate 15 is fixedly provided with a positioning rod 20. The positioning rod 20 and the second plate 18 are movably fitted together, and the positioning rod 20 and the vertical frame 2 are movably fitted together. With this arrangement, when splicing the horizontal frame 1 and the vertical frame 2, the horizontal frame 1 and the vertical frame 2 can be quickly positioned, so that the protrusion 5 can be quickly aligned with the triangular slot, thereby improving the efficiency of the horizontal frame 1 and the vertical frame 2 being engaged.

[0036] Working principle: During use, the protrusion 5 and rectangular block 6 on the vertical frame 2 are inserted into the triangular and rectangular slots respectively. During insertion, the inclined structure on the insertion rod 9 pushes the insertion rod 9 and the limiting plate 8 into the limiting groove 7, allowing the rectangular block 6 to smoothly insert into the rectangular slot. At this time, the insertion rod 9 and the fixing groove 10 are in opposite positions, and the first spring 12 restores its elasticity, driving the insertion rod 9 into the fixing groove 10, quickly completing the connection between the horizontal frame 1 and the vertical frame 2. The snap-fit ​​fixing method facilitates the handling or transportation of the subframe. After the subframe is assembled, it is bonded to the window on the wall with expanding foam. The first folding plate 13 and the second folding plate 14 increase the contact area between the expanding foam and the subframe. To prevent the expanding foam from leaking out, taking the horizontal frame 1 as an example, the first movable plate 16 and the second spring 17 are used to ensure that the first movable plate 16 fits tightly against the window on the wall, and the expanding foam is confined between the two first plates 15, thereby preventing the expanding foam from leaking out.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
