Description

Technical Field

[0001] The utility model belongs to the technical field of doors and windows, and in particular relates to an automatic regulating and locking device for doors and windows. Background Art

[0002] Windows allow light or air to enter a room. Common windows are composed of three parts: window frames, glass, and movable components. The window frames are responsible for supporting the main structure of the window. The movable components are mainly made of metal materials, and places that are touched by human hands may also be wrapped with insulating materials such as plastic.

[0003] During the use of windows, it is necessary to use window locks to lock them. Existing window locks are manual. Generally, the direction of the handle rotation drives the alignment plate on the fixed seat to rotate to the fixed plate on the other side, so that the alignment plate and the fixed plate are stuck together, and the two windows are locked and fixed. However, during the use of this structure, the overall volume of the handle structure of the lock is relatively large, and it is necessary to rotate a certain angle to realize the rotation of the alignment plate. Existing doors and windows are generally self-locking driven by multiple sensors or by extrusion and adsorption. The former has a high production cost and is not convenient for subsequent maintenance work. When self-locking is performed by extrusion and adsorption, there is a lack of the function of adjusting the extrusion and adsorption force, so that after the user inadvertently closes the door and window, it forms a self-locking, and the door and window need to be reopened. It is impossible to self-lock according to one's own needs, and the window angle cannot be locked and fixed after adjustment. Therefore, it is necessary to design an automatic adjustment locking device for doors and windows. Utility Model Content
