When working, when the upper hanging window 2 is pushed out, the staff can open the telescopic arm 25 and slide the support arm 26 outward to adjust the distance, which plays an auxiliary fixing role for the upper hanging window 2. The elastic force of the spring four 27, combined with the positioning piece 28 and the positioning hole, can make the support arm 26 fixed on the telescopic arm 25 after adjustment, which is convenient for people to use.

[0037] Example 2:

[0038] like Figure 7 As shown, the assembled aluminum alloy doors and windows and the installation method thereof described in the present invention have a seal 29 fixed in the limiting slide groove at the bottom of the lower frame 23, and the seal 29 is in contact with the limiting protrusion 22; during operation, the seal 29 is fixed on the inner wall of the limiting slide groove to ensure the sealing between the lower frame 23 and the mounting track 21, thereby preventing rainwater from leaking into the top-hung window 2 through the gap between the limiting protrusion 22 and the lower frame 23 when it rains, thereby affecting the normal use of the window.

[0039] Working principle: when in use, the window has two ways to open. By pushing the upper hanging window 2 outward, outside air can enter the window. At the same time, it can be used on rainy days to prevent a large amount of rainwater from penetrating. When the upper hanging window 2 is pushed out, it can be fixed by the cooperation between the telescopic arm 25 and the support arm 26. By closing the upper hanging window 2, the horizontal sliding window 3 is opened, so that outside air can enter. Compared with the upper hanging window 2, the horizontal sliding window 3 is more conducive to the flow of air. When assembling, first, the staff fixes the mounting frame 1 on the window frame, and then aligns the fixing piece 7 on the upper hanging window 2 with the mounting piece on the mounting frame 1, and slides the fastening piece 2 9 on one side of the fixing piece 7 into the fastening piece 6 on the outside of the mounting piece. Secondly, rotate the locking bolt 14 inward so that the locking bolt 14 enters the limit cavity 1 and presses against the fastening piece 1 8 and drives the fastening piece 1 8 to slide inward. The fastening piece 1 8 drives the connecting piece 11 to slide while sliding, so that the connecting piece 11 on the other side The upper frame 16 is pressed against the extrusion plate 20 and the positioning slider 17 corresponds to the positioning slot on the extrusion plate 20, and the upper frame 16 is pushed upward so that the extrusion plate 20 compresses the elastic limiting component until the limiting protrusion 22 on the mounting track 21 slides into the limiting slot on the lower frame 23, completing the installation of the horizontal sliding window 3. Compared with the traditional window, the present invention combines the two window structures of top-hung window 2 and horizontal sliding window 3, which enriches the choices of users while ensuring a certain aesthetics, and the installation method is simple, which is convenient for the staff to quickly install and disassemble the window.

[0040] The installation method of assembled aluminum alloy doors and windows is applicable to any of the assembled aluminum alloy doors and windows described above. The steps of the method are as follows:

[0041] S1: The operator first fixes the installation frame to the window frame, then aligns the fixings on the top-hung window with the mounting parts on the installation frame, and slides the second fastener on one side of the fixing part into the snap-fit part on the outside of the mounting part;

[0042] S2: Rotate the locking bolt inward, so that the locking bolt enters the limiting cavity 1, presses against the fastening member 1, and drives the fastening member 1 to slide inward. The fastening member 1 drives the connecting member to slide at the same time, so that the limiting member on the other side of the connecting member slides inward accordingly, until the limiting member and the fastening member on the same side of the fastening member 2 are in contact with each other. At this time, the fastening member 1 is in contact with the fastening member on the other side, thereby completing the fastening action, so that the fixing member and the mounting member are fixed together;

[0043] S3: The staff member slides the top of the horizontal sliding window obliquely into the installation groove of the first installation track, so that the upper frame abuts against the pressing plate upward while the positioning slider corresponds to the positioning chute on the pressing plate. Then, continue to push the upper frame upward, so that the pressing plate compresses the elastic limiting component until the limiting protrusion on the second installation track slides into the limiting chute on the lower frame, completing the installation of the horizontal sliding window.

7. Installation method of assembled aluminum alloy doors and windows, characterized in that, The method is applicable to the assembled aluminum alloy doors and windows according to any one of claims 1 to 6, and the steps of the method are as follows: S1: The operator first fixes the installation frame to the window frame, then aligns the fixings on the top-hung window with the mounting parts on the installation frame, and slides the second fastener on one side of the fixing part into the snap-fit part on the outside of the mounting part; S2: Rotate the locking bolt inward, so that the locking bolt enters the limiting cavity 1, presses against the fastening member 1, and drives the fastening member 1 to slide inward. The fastening member 1 drives the connecting member to slide at the same time, so that the limiting member on the other side of the connecting member slides inward accordingly, until the limiting member and the fastening member on the same side of the fastening member 2 are in contact with each other. At this time, the fastening member 1 is in contact with the fastening member on the other side, thereby completing the fastening action, so that the fixing member and the mounting member are fixed together; S3: The staff tilts the top of the horizontal sliding window and slides it into the installation groove of the installation track 1, so that the upper frame presses against the extrusion plate and the positioning slider corresponds to the positioning groove on the extrusion plate. The upper frame is continued to be pushed upward, so that the extrusion plate compresses the elastic limit assembly until the limit protrusion on the installation track 2 slides into the limit groove on the lower frame, completing the installation of the horizontal sliding window.
