The existing double-chain sliding arm window opener with inward-opening motor has low space utilization, resulting in insufficient length of the winding roller, which limits the opening angle and affects the indoor ventilation effect.
The design employs a drive wheel, belt, and driven wheel. The driven wheel is driven to rotate by the belt inside the hollow column, increasing the length of the chain roller. Combined with the double chain structure, this improves the rotation angle of the small window frame. A waterproof rubber ring is also installed on the small window frame to enhance its sealing performance.
It increases the amount of fresh outdoor air entering the room, improves indoor air quality, and enhances the sealing of the small window frame to prevent rain and dust from entering the room.
