Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to an anti-fall safety door and window. Background technique [0002] A lot of doors and windows on the market are outward-opening windows, and hinges or hinges are usually used to connect the window frame and the window sash for the normal opening and closing of the window frame and the window sash. Due to the relatively small wind force on the ground, the safety performance of ordinary outward opening windows is sufficient to meet the needs of low-rise buildings. None of the connecting accessories can ensure that the open state can withstand high wind pressure, and it cannot guarantee that the window sash will not be damaged or even fall off. In harsh environments such as storms, typhoons and even hurricanes, it is even more difficult to guarantee the safety and stability of outward-opening windows. When the window sash falls from a high altitude, it will cause great sa...

Problems solved by technology

Due to the relatively small wind force on the ground, the safety performance of ordinary outward opening windows is sufficient to meet the needs of low-rise buildings. The connection accessories cannot ensure that the open state can withstand high wind pressure, and cannot guarantee that the window sash will not be damaged or even fall off. In harsh environments such as storms, typhoons and even hurricanes, it is even more difficult to guarantee the safety and stability of outward opening windows.

When the window sash falls from a high altitude, it will cause great safety hazards to the people around the building and other things. Therefore, the field is in urgent need of a high-stability anti-fall safety door and window that can solve the above problems.
