Electric top-opening windows 01
Adjustable Greenhouse Automatic Roof Vent and Opener
The rack of the system is hinged with the window, the rack is engaged on the rack, the gear is fixed on the drive shaft, and the drive shaft is supported by the bearing seat. When the reducer rotates, the drive shaft drives the rack and pinion to move, so as to realize the opening and closing of the window.
