Working Principle: The roller and pull cord linkage mechanism.
The core of the bamboo roller blind is the spring-loaded roller tube structure at the top. When the cord is pulled, the roller tube rotates, causing the bamboo blind to roll upwards.
This mechanical design is based on the principle of balance. An internal spring or counterweight system ensures the blind can stop at any height, providing stable and smooth operation.
Pulling the upward cord automatically retracts the blind; pulling the downward cord unfolds the blind. The entire process requires no additional power source.
