Description

A self-locking hanging window with stepless opening and closing

technical field

The utility model relates to windows, in particular to a stepless opening and closing self-locking hanging window.

Background technique

Windows are widely used in residential houses, hotels and office buildings, etc., to play the roles of lighting, ventilation, rainproof and beautifying the environment.

Most of the existing windows are opened sideways or pushed horizontally. When it rains, rainwater is easy to enter the house, and it is mainly used in residential houses. Most of the windows that are opened horizontally do not have self-locking properties (self-locking properties mean that the windows will not be closed even if they are subjected to a large external force, such as wind); Refers to the window opening size can be adjusted at will) the operation of opening is troublesome, and the self-locking performance is not good. There are grades (there are grades refers to the adjustment of the window opening size in steps). The opening operation is simple and the self-locking performance is good, but it cannot be adjusted at will size.

Compared with windows that open sideways or push open horizontally, rainwater from hanging windows is not easy to enter the house, so it is mainly used in hotels and office buildings. At present, the hanging windows cannot be opened steplessly. If the self-locking property fails due to changing loads (changes in the magnitude and direction of the force), external influences such as wind will cause changes in the opening and closing of the windows, or even break the glass. A big security risk.
