Description

[0002] Villa ceiling curtains are curtains designed specifically for the high spaces in villas. Their characteristics are that they can adapt to higher windows or ceilings while providing functions such as aesthetics, shading, and privacy protection.

[0003] Although the lifting devices currently on the market generally use at least two sets of steel wire ropes to coordinately control the lifting and lowering of curtains, in actual operation, due to the uneven winding thickness of the steel wire ropes during the winding process and the possible loose winding state, the winding lengths of the two sets of steel wire ropes are often inconsistent, which in turn causes the curtains to tilt when they are raised or lowered, which not only damages the aesthetics of the curtains, but also brings unnecessary troubles and inconveniences to users.
