Description

An electric lifting window with good airtightness

technical field

The utility model relates to the technical field of doors and windows, in particular to an electric lifting window with good airtightness.

Background technique

The closed balcony, living room or office window sashes of traditional buildings are generally of flat opening or push-pull type, which cannot be fully opened under sunny weather conditions, and better ventilation effects cannot be enjoyed indoors. With the development of the economy and the improvement of people's living standards, people's requirements for windows are getting higher and higher. In recent years, a kind of electric lift window has appeared for balcony sealing and windows. Its structure mainly includes the outer movable sash and the inner fixed sash (the inner side refers to the indoor side, and the outer side refers to the outdoor side). The movable sash can be fully opened when it is lowered, and the ventilation area is large, so it is very popular. However, in order to move smoothly, there is usually a gap between the movable sash and the fixed sash, resulting in poor airtightness. The traditional method is to install wool strips between the movable sash and the fixed sash to seal the gap, but the wool strips have poor sealing performance and cannot be effective. Solve the problem of poor airtightness of electric lift windows. At present, there is also a way to achieve airtightness by using a translational window, that is, when the movable sash moves to the closed position, it will translate towards the fixed sash to squeeze the sealing strip between the two to achieve airtightness, but the translation mechanism Complex and easily damaged, resulting in high manufacturing, disassembly and maintenance costs.
