Description

technical field [0001] The invention relates to the technical field of positioning locks for doors and windows, and more particularly to a door and window positioning lock with a positioning self-locking function. Background technique [0002] Doors and windows can be seen everywhere in our daily life. Doors and windows can not only increase indoor light transmission but also ensure indoor ventilation at any time. Now there will be automatic ventilation doors and windows on the market, which can be automatically controlled under human control. Open and close, but these ventilation windows also have large loopholes during use. For example, there are only two states of opening and closing during use. The user cannot control the opening size of the window through their own will. When the user places their hands or foreign objects on the window sill, the forced closing of the ventilation window under the drive of the motor will cause personal injury to the user or to the user. ...

[0002] Doors and windows can be seen everywhere in our daily life. Doors and windows can not only increase the light transmission in the room but also ensure the ventilation of the room at any time. Now there will be automatic ventilation doors and windows on the market, which can be realized automatically under human control when in use. Open and close, but these ventilation windows also have relatively large loopholes in the process of use, for example, there are only two states of open and closed during use, and the user cannot control the size of the window opening by his own will. When the user puts his hands or foreign objects on the window sill, the ventilation window will be forced to close under the drive of the motor, which will cause personal injury to himself or the user. A door and window positioning lock with positioning self-locking function, which can automatically stop when there are foreign objects in the window, is really necessary
