This, in turn, restricts the movement of the door and window, achieving stable limiting of the door and window. The device is easy to operate and avoids scratches on the surface of the door and window. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1
[0023] Please see Figures 1-2 The present invention provides a technical solution: a limiter for aluminum alloy doors and windows, the limiter for aluminum alloy doors and windows includes: a mounting box 1, a fixed rack 8 is provided at the bottom of the mounting box 1, a meshing gear 9 is provided on the fixed rack 8, the gear 9 is provided on a rotating shaft 10, a rotating shaft 12 is slidably connected inside the rotating shaft 10, the rotating shaft 12 is rotatably connected to the mounting box 3, and a limit component is provided on the rotating shaft 12;
[0024] The mounting box 3 is installed on the window frame. The rotating shaft 12 is rotatably connected to the mounting box 3, which in turn drives the gear 9 to rotate through the rotating shaft 10. As the mounting box 3 moves, the gear 9 meshes with the fixed rack 8, causing the gear 9 to rotate. This causes the rotating shaft 12 to rotate on the mounting box 3. When it rotates to a certain position, the rotation of the rotating shaft 12 is restricted by the limiting component, thereby restricting the movement of the mounting box 3 and preventing it from being pushed. This restricts the movement of the door and window, achieving stable limiting of the door and window. The operation is convenient and avoids scratches on the surface of the door and window.
[0025] Example 2
[0026] like Figures 3 to 5As shown, based on Embodiment 1, stable positioning of doors and windows is achieved. The mounting box 1 has a box-like structure. A sealing plate 2 is provided on the side of the mounting box 1. A clearance groove 6 is formed on the sealing plate 2, through which a rotating shaft 10 passes. One end of the rotating shaft 10 is slidably connected to a slide rail 7. The slide rail 7 has a "U"-shaped plate structure and is installed on the inner surface of the upright plate of the mounting box 1. An installation groove 20 is formed at the other end of the rotating shaft 10. The installation groove 20 has a "+"-shaped groove structure, through which one end of a rotating shaft 12 is slidably connected. One end of the rotating shaft 12 has a boss. The rotating shaft 12 passes through a cover plate 11, which is located on the surface of the other end of the rotating shaft 10. The rotating shaft 12 passes through a sealing plate 2. Plate 2 4 is set on the side of the mounting box 3. The mounting box 3 has a box-type structure. The other end of the rotating shaft 2 12 is rotatably connected to the upright plate of the mounting box 3. The rotating shaft 2 12 is provided with a limit gear 14. The upper part of the limit gear 14 meshes with the movable rack 16. The movable rack 16 is provided with sliders 18 on both sides. The sliders 18 are slidably connected in the slide groove 19. Two sets of slide grooves 19 are opened on both sides of the mounting box 3. The top surface of the movable rack 16 is rotatably connected to one end of the connecting shaft 13. The connecting shaft 13 is provided with two sets of limit blocks 15. The connecting shaft 13 passes through the through hole 17. The through hole 17 has a "+" shaped hole structure. The through hole 17 is opened on the top plate of the mounting box 3. The other end of the connecting shaft 13 is connected to the operating handle 5.
[0027] When the mounting box 3 moves, it drives the second rotating shaft 12 forward, which in turn drives the gear 9 forward through the first rotating shaft 10. As the gear 9 moves forward, it meshes and rotates on the fixed rack 8, which in turn drives the first rotating shaft 10 to rotate. Under the action of the first rotating shaft 10, the second rotating shaft 12 rotates on the mounting box 3. That is, the second rotating shaft 12 rotates while moving. After the door and window reach a certain position, the operating handle 5 is turned. The operating handle 5 drives the connecting shaft 13 to rotate in the movable rack 16, which in turn moves the connecting shaft 13 downward, allowing the limiting block 15 to pass through the through hole 17. This causes the movable rack 16 to move downward, and the teeth of the movable rack 16 mesh with the limiting gear 14, restricting the rotation of the limiting gear 14. In turn, the rotation of the gear 9 is restricted through the second rotating shaft 12 and the first rotating shaft 10. Thus, the gear 9 restricts the movement of the mounting box 3, thereby limiting the mounting box 3.
[0028] In actual use, the back of the mounting box 3 is installed on the window stile, and the mounting box 1 is installed on the window frame. A sliding mechanism is provided between the first rotating shaft 10 and the second rotating shaft 12 to accommodate window frames of different thicknesses. As the door or window moves, the mounting box 3 moves as well. When the mounting box 3 moves, it drives the second rotating shaft 12 forward, which in turn drives the gear 9 forward via the first rotating shaft 10. As the gear 9 moves forward, it meshes and rotates on the fixed rack 8, thereby driving the first rotating shaft 10 to rotate. Under the action of the first rotating shaft 10, the second rotating shaft 12 rotates on the mounting box 3. The movement occurs when the rotating shaft 12 moves and rotates. After the door and window reach a certain position, the operating handle 5 is rotated. The operating handle 5 drives the connecting shaft 13 to rotate within the movable rack 16, thereby moving the connecting shaft 13 downward and passing the limiting block 15 through the through hole 17. This causes the movable rack 16 to move downward, and the teeth of the movable rack 16 mesh with the limiting gear 14, restricting the rotation of the limiting gear 14. In turn, the rotation of the gear 9 is restricted through the rotating shaft 12 and the rotating shaft 10, and the gear 9 restricts the movement of the mounting box 3, thus achieving the limitation of the mounting box 3.
