The window mainly comprises a window frame and a window sash, wherein the window frame and the window sash are movably connected through hinges, and the hinges mainly comprise rotating type hinges, sliding support type hinges and the like. For example, a hinge used in a casement window, that is, the whole window sash of the casement window is horizontally pushed outwards in the using process of the casement window, and relative to a rotary casement window, the window sash and a building surface (such as a glass curtain wall) cannot form an included angle, so that a facade effect difference (such as inconsistent light reflection) is generated; secondly, after the horizontal sliding type window is opened, gaps are reserved around the window sash, air can enter and exit to conveniently form circulation, and ventilation volume and fresh air volume are increased. As a result, many owners and architects of projects, particularly office building projects, are increasingly looking for and prefer to use window types such as flat push windows.
