Technical Field

The invention relates to the technical field of a hung window, in particular to a strong wind preventing self-closing hung window.

Background

The hung window is a window opened along a horizontal shaft and is divided into an upper hung window, a lower hung window and a middle hung window according to the difference of the positions of a hinge and a rotating shaft. Wherein the center-hung window: the horizontal rotating shafts are arranged in the middle of two sides of the window sash, and the window sash has the advantages of convenience in opening and closing, labor saving and rain prevention. The suspended window is widely applied to high-rise buildings, but in the long-term use process, the suspended window is not closed, so that strong wind blows into a room, paper documents in the room are blown down, and even the paper documents are blown out of the room due to air convection, so that the possibility of document loss is found; if the weather is rainy, raindrops can splash into the room, so that water enters the floor, and even the floor is damaged, thereby causing economic loss.

In order to solve the problems, the strong wind preventing self-closing center-hung window is provided.
