AI Technical Summary

Technical Problem

Existing blinds with manual rotation mechanisms are prone to entanglement issues due to the reeling structure being placed at the upper end, leading to difficulties in controlling the blades effectively.

Method used

A bottom-controlled built-in shutter structure with a connecting structure, clamping structure, and lifting rope system that allows for smooth operation and folding of blades by pulling the lifting rope, utilizing a sleeve rod, limit frames, and clamping mechanism to maintain the blades in an open or folded state.

Benefits of technology

The solution provides a reliable and efficient mechanism for controlling the blades, preventing entanglement and ensuring smooth operation with the blades folding upward and stacking, while maintaining the desired position through the clamping mechanism.
