AI Technical Summary
The existing double-chain hand-cranked window opener has high production costs, complex material preparation, and difficult management due to the symmetrical design of the left and right core parts, which affects production efficiency and product quality.
A double-chain hand-cranked window opener mechanism is designed, which achieves symmetrical installation of the left and right mechanisms using a single specification of parts. The combination structure of mechanism housing, chain guide compartment, mounting base, shaft, sprocket, worm gear, chain guide bar and worm simplifies the types of parts and the installation process.
It reduced mold opening costs, reduced the types of parts, simplified material preparation and warehousing management, and improved production efficiency and product quality.
