Description

Technical Field

[0001] The utility model relates to the technical field of doors and windows, and specifically discloses a positioning mechanism. Background Art

[0002] Drift window is a window style that looks similar to casement window. It opens by tilting and sliding inwards. That is, after turning the handle and opening the window sash, it is directly pushed and pulled to one side to achieve the translation function. Therefore, it has the characteristics of small footprint, good sealing, high safety and good sound insulation.

[0003] However, the window sash of the existing drift window can only be fixed on both sides of the window frame. When the user stops the window sash at a certain position within its translation stroke for semi-ventilation, if the wind is strong, the window sash will be displaced due to the wind and the ventilation level required by the user cannot be maintained.
