In the traditional window structure, the opening and closing of the window sash is generally to place the window sash in the preset slide rail of the window frame, through the push-pull opening and closing in the slide rail; or to install the window sash on the window frame by rotating the hinge . Due to the limitation of the window frame, the above-mentioned traditional window structure can generally only realize the opening and closing of a single sash, and cannot realize the large-area opening and closing of the window for a long-span window.

In response to this problem, a folding window structure has appeared in the prior art, and multiple sashes are arranged together in a long and large window frame. The multiple sashes are generally connected end to end and stacked together in a "W" shape. Achieve greater opening of large window frames. However, the prior art has the following problems: (1) Since each sash is connected end to end all the time, all sashes are always connected together to form a windshield surface. When the window is expected to be ventilated in a small amount, only a small amount of the movable end at the edge of the window can be opened. Taking the left end as the movable end of the window sash as an example, the sash can only be slightly opened at the left end of the window for ventilation, but the sash on other parts of the window is still in the shape of a "W" and stops in the window frame, which is not convenient for a small amount of uniform ventilation in other parts of the window , for large-span windows, such as large-span wide-view balconies, it is not convenient for users to evenly ventilate the room; (2) some existing folding mechanisms occupy too large installation area, and the folding mechanism is relatively large for the number of sash. The compatibility and expansion ability of the sash are poor, and it is not convenient to flexibly adjust the number of sash according to the demand. For example, in the patent document CN215056646U, the length of the crank used for folding the sash is much larger than the size of the sash after the sash is folded, so that the crank will occupy a large space after the sash is folded. It is not convenient for hidden storage, and this folding structure is only suitable for folding windows with three sashes, so it is not convenient to adjust the number of sashes according to demand.
