Fix the position, completing the assembly and fixation between the slide rail 23 and the door frame 11. Simultaneously, manually move the arc plate 29 to a position where it fits against the surface of the door leaf 12, so that the inner wall of the hole on the arc plate 29 coincides with the inner wall of the second threaded groove. At this time, use a tool to screw the second bolt 210 into the arc plate 29 and the second threaded groove to fix the position of the arc plate 29. Then, manually rotate the threaded post 211, causing the threaded post 211 to move up and down along the inside of the arc plate 29, so that the threaded post 211 moves to the position inside the slide rail 23. When the door leaf 12 is rotated and opened, the door leaf 12 moves... The movement of the curved plate 29 causes the threaded column 211 to slide along the inside of the slide rail 23. When the threaded column 211 reaches the contact position with the inner wall of the slide rail 23, it is intercepted by the slide rail 23. The slide rail 23 intercepts the curved plate 29 and the door leaf 12 through the threaded column 211, so that the door leaf 12 cannot move further after opening to a certain gap. This keeps the gap between the door leaf 12 and the door frame 11 within a safe range, thereby protecting children and reducing the possibility of children climbing the door frame 11 after the door leaf 12 is fully opened, which could lead to accidental falls. This improves the safety of using doors and windows.
[0028] Figure 3-6 The surface of the threaded post 211 shown is provided with multiple anti-slip strips 212, which are arranged at equal intervals. By setting the anti-slip strips 212, the friction between the hand and the surface of the threaded post 211 can be increased, reducing the possibility of slipping when manually rotating the threaded post 211. A rubber pad 25 is fixed to the inner wall of the slide rail 23. By setting the rubber pad 25, the moving threaded post 211 can be blocked, reducing the collision and wear between the threaded post 211 and the inner wall of the slide rail 23.
[0029] Figure 3-6 A storage groove 28 is provided on one side of the slide rail 23 shown. The inner wall of the storage groove 28 is larger than the surface of the nut of the first bolt 24. By setting the storage groove 28, the nut of the first bolt 24 can be completely inserted into it, reducing the situation where the nut of the first bolt 24 protrudes above the surface of the slide rail 23 and hinders the normal movement of the arc plate 29.

The limit rod 213 is placed inside the limit groove 22 to assist in limiting the arc plate 29. By setting the limit rod 213, the limit rod 213 can be placed inside the limit groove 22 to assist in limiting the arc plate 29, reducing the possibility of the arc plate 29 rotating under force during use.
[0030] Figure 3-6 The slide rail 23 shown has multiple round holes, and a pin 26 is slidably connected to the inner wall of each round hole. The pin 26 is made of magnetic metal. Through the pin 26, a person can insert the pin 26 into the slide rail 23 through any of the round holes to block the threaded post 211. The maximum movement distance of the threaded post 211 can be adjusted by using the spacing between the multiple round holes, thereby adjusting the opening range of the door leaf 12. A magnetic ring 27 is fixed to the side of the slide rail 23 near the multiple round holes. The magnetic ring 27 is fixed to the pin 26 by adsorbing it. By setting the magnetic ring 27, the magnetic ring 27 can be used to assist in fixing the pin 26 by adsorbing it, reducing the possibility of the pin 26 sliding out of the slide rail 23 from the round hole.
[0031] Working principle: First, manually move the slide rail 23 to the position where it is fully inserted into the slot 21, so that the inner wall of the first threaded groove inside the slot 21 coincides with the inner wall of the hole on the slide rail 23. At this time, use a tool to screw the first bolt 24 into the slide rail 23 and the first threaded groove to fix the position of the slide rail 23, completing the assembly and fixation between the slide rail 23 and the door frame 11. At the same time, manually move the arc plate 29 to the position where it is in contact with the surface of the door leaf 12, so that the inner wall of the hole on the arc plate 29 coincides with the inner wall of the second threaded groove. At this time, use a tool to screw the second bolt 210 into the arc plate 29 and the second threaded groove to fix the position of the arc plate 29. Then, manually rotate the threaded post 211, so that the threaded post 211 moves up and down along the inside of the arc plate 29, so that... The threaded post 211 moves to a position inside the slide rail 23. When the door 12 is rotated open, the door 12 causes the arc plate 29 to move, which in turn causes the threaded post 211 to slide along the inside of the slide rail 23. When the threaded post 211 moves to a position where it contacts the inner wall of the slide rail 23, it is intercepted by the slide rail 23. The slide rail 23 intercepts the arc plate 29 and the door 12 through the threaded post 211, so that the door 12 cannot move further after opening to a certain gap. This keeps the gap between the door 12 and the door frame 11 within a safe range, thus protecting the child. At the same time, a person can insert the latch 26 through any of the round holes into the position inside the slide rail 23 to block the threaded post 211, further adjusting the opening range of the door 12.
