AI Technical Summary
Existing window hinges are inconvenient to operate and difficult to adjust precisely when adjusting the gap between the window sash and the window frame, mainly relying on the installer's feel and observation.
The system employs a toothed pin and toothed hole meshing transmission method. Each tooth pitch serves as the adjustment distance. When the toothed pin moves one tooth pitch relative to the toothed hole, the connecting plate drives the main support plate and the sash fixing plate to move one tooth pitch relative to the frame fixing plate, thereby achieving precise adjustment of the gap between the window sash and the window frame.
It enables precise adjustment of the gap between the window sash and the window frame, improving the accuracy of adjustment and the convenience of operation.
