Under the guidance of the T-shaped groove, the windproof sheet and the mesh are deformed from a straight line into a T-shape and slide in the strip groove.

[0042] In this embodiment, the bottom surface of the tank chain body is provided with an n-shaped guide groove 7 that mates with the lower rail; the magnetic suction component is embedded and fixed on the top wall of the n-shaped guide groove. In practical application, an n-shaped protrusion 12 is provided on the lower rail, which, in conjunction with the n-shaped guide groove, allows the n-shaped protrusion to engage with the n-shaped guide groove when the tank chain body moves horizontally, preventing displacement or loosening and improving stability during use. Furthermore, in practical application, a C-shaped groove 14 can be provided along the symmetrical edge of the n-shaped protrusion, and a hook 15 is provided on the inner wall of the n-shaped guide groove. The hook engages with the C-shaped groove when the tank chain body sways, preventing lateral displacement or detachment.

[0043] This utility model has positive effects: The structure of this utility model is reasonably designed. A magnetic suction element is embedded in the bottom surface of the tank chain body, and it works in conjunction with a matching magnetic suction strip in the lower rail of the screen door and window frame. When the tank chain body is laid flat, the magnetic suction element and the matching magnetic suction strip magnetically attract and limit the movement of the tank chain body caused by external force, which can effectively prevent the tank chain body from moving or tilting upwards, thus improving the stability and reliability of use. In addition, the top surface of the tank chain body is provided with a guide T-shaped groove for guiding and limiting the horizontal movement of the screen, which can limit the bottom edge of the screen and prevent the screen from shifting or falling off, thus improving the effectiveness and stability of the screen. Example 2

Specifically, the width of the n-shaped guide groove is greater than the width of the n-shaped protrusion, which facilitates insertion and disengagement operations, and also facilitates the use of the C-shaped groove and the lateral displacement anti-disengagement hook. During use, the n-shaped protrusion, in conjunction with the n-shaped guide groove of the tank chain body, can prevent the side displacement of the tank chain body, improving the stability of use. At the same time, a quick-release and quick-installation clearance groove 13 for the screen box is provided at the connection between the bottom wall end of the screen door / window frame and the screen box. Figure 5 As shown, the bottom movable screen box seat of the screen box is provided with a locking anti-detachment protrusion 18 that cooperates with the clearance groove. The shape of the clearance groove and the locking anti-detachment protrusion allows the movable pull rod and screen box to be disassembled and assembled from the screen door and window frame in a very narrow space, improving the convenience and effectiveness of disassembly and assembly.

[0050] In this embodiment, in order to improve the side anti-detachment performance, there is a C-shaped groove 14 on the symmetrical sidewall of the n-shaped protrusion, and a lateral displacement anti-detachment hook 15 on the lower part of the symmetrical inner wall of the n-shaped guide groove; when the tank chain body is laid flat, the lateral displacement anti-detachment hook is locked into the C-shaped groove for limitation, and the hook is locked into the C-shaped groove when the tank chain body shakes to prevent lateral displacement or detachment.

[0051] This utility model has positive effects: its invisible screen door and window has a simple overall structure, adopting a tank chain body, a balance pull rod body and a movable pull rod. The movable pull rod and the magnet on the balance pull rod body can be quickly magnetically attracted and disassembled, thereby ensuring the effectiveness and reliability of the screen operation. At the same time, it is also conducive to the quick disassembly and assembly of the movable pull rod, screen box and screen door and window frame, improving the efficiency and convenience of disassembly and assembly, and has strong applicability.
