Embodiment

[0023] Figures 1-4The closing structure of an aluminum alloy window and door according to an embodiment of the present invention is shown, which includes a second mounting piece 7 installed on the front side of the main frame 1 of the window and door by screws: a glass window and door 2 is installed on the rear side of the inner cavity of the main frame 1 of the window and door. The glass window and door 2 includes an aluminum alloy frame 21 rotatably connected to the rear side of the inner cavity of the main frame 1 of the window and door by a hinge. A hollow glass 22 is hermetically installed in the inner cavity of the aluminum alloy frame 21. A screen window and door 3 is rotatably connected to the front side of the inner cavity of the main frame 1 of the window and door. The screen window and door 3 includes an aluminum alloy frame 31 rotatably connected to the front side of the inner cavity of the main frame 1 of the window and door by a hinge. A screen curtain 32 is hermetically installed in the inner cavity of the aluminum alloy frame 31. A first mounting piece 4 is fixedly installed on the front side of the screen window and door 3 by a plurality of screws. A rotating shaft 5 is welded to the front side of the first mounting piece 4. A flexible piece 6 is fixedly connected to the rotating end of the rotating shaft 5. A storage box 8 is welded to the front side of the second mounting piece 7. The flexible piece 6 is slidably connected to the inner cavity of the storage box 8. A plurality of first teeth 9 are fixedly installed on the front side of the flexible piece 6. A chute 10 is formed inside the storage box 8. A sliding rod 11 is slidably connected to the inner cavity of the chute 10. A rectangular piece 13 is welded to the rear end of the sliding rod 11. A plurality of second teeth 14 meshing with the first teeth 9 are fixedly installed on the rear side of the rectangular piece 13. A spring 15 is sleeved on the surface of the pulling piece 12. The rear end of the spring 15 is in contact with the front side of the rectangular piece 13. The front end of the spring 15 is in contact with the front side of the inner cavity of the chute 10.

[0024] Working principle: When the present invention is in use, the user installs the second mounting piece 7 and the first mounting piece 4 on the front sides of the main frame 1 of the window and door and the screen window and door 3 at the corresponding positions by screws and bolts respectively. If the user wants to open or close the glass window and door 2, at this time, the user needs to keep pulling the pulling piece 12 forward with one hand, so that the pulling piece 12 drives the sliding rod 11 to move forward in the inner cavity of the chute 10, and then the sliding rod 11 drives the plurality of second teeth 14 on the rectangular piece 13 to move forward and disengage from the engagement with the plurality of first teeth 9. At this time, pull the right side of the flexible piece 6 to the right with the other hand, and then release the pulling piece 12. Normally open the screen window and door 3 so that there is a gap between the main frame 1 of the window and door and the screen window and door 3 to open or close the glass window and door 2. Then the user directly pulls the flexible piece 6 to the left on the left side of the flexible piece 6. Since the left side of the first teeth 9 is a slope and the right side of the second teeth 14 is a slope, when pulling the flexible piece 6 to the left, the first teeth 9 and the second teeth 14 are squeezed and engaged, and at the same time the spring 15 is compressed and rebounds, so that the operation of narrowing the gap between the main frame 1 of the window and door and the screen window and door 3 is more convenient. Until the flexible piece 6 between the main frame 1 of the window and door and the screen window and door 3 becomes tight, so that the screen window and door 3 will not have a large gap with the main frame 1 of the window and door even when unlocked, the purpose of facilitating the opening and closing of the glass window and door can be achieved.

[0025] In summary: For the closing structure of the aluminum alloy window and door, through the combined use of the window and door main frame 1, the glass window and door 2, and the screen window and door 3, the overall aluminum alloy window and door is formed. Through the combined use of the sliding groove 10, the sliding rod 11, and the rectangular piece 13, the second tooth 14 is driven to move back and forth, and then meshes with or disengages from the first tooth 9, so that the flexible piece 6 is limited in the inner cavity of the storage box 8. Then, the size of the gap between the window and door main frame 1 and the screen window and door 3 can be changed, so that the opening position of the screen window and door 3 is limited, and the purpose of facilitating the opening and closing of the glass window and door can be achieved.
