AI Technical Summary
Existing roof window lifting devices struggle to effectively balance the weight of the windows when facing roofs with varying slopes, leading to operational difficulties and potential hazards.
The worm gear adjustment system, including a threaded worm and a worm wheel, is adopted. The adjustment of the lifting device is achieved by the rotation of the worm gear, which allows operation from one side, reduces the need for direct tool placement, and can adapt to different roof slopes by adjusting the position of the connection point.
It achieves window balance under different roof slopes, provides a safe and flexible operating method, reduces the need for direct tool placement, and improves the ease of window operation and safety.
