Abstract:
Disclosed is a Roman blind, comprising an upper beam (1), a winding pipe (2), a Roman blind body (3) and a roller blind body (4). Both ends of the winding pipe (2) are connected to both ends of the upper beam (1) by means of connecting members (5); the upper end of the roller blind body (4) is wound on the winding pipe (2); the upper end of the Roman blind body (3) is fixed to the upper beam (1); the lower end of the roller blind body (4) is synchronously linked with the lower end of the Roman blind body (3) for lifting and lowering; several position limiting members (6) arranged at equal intervals are provided on the surface of the Roman blind body (3) facing the roller blind body (4); a driving member (7) matching the position limiting member (6) is provided at the lower end of the roller blind body (4) so as to drive the Roman blind body (3) to be folded layer by layer from bottom to top. The folding and unfolding of the Roman blind body (3) are driven to by means of the winding and unwinding of the roller blind body (4), so that pull-rope-free winding and unwinding are realized, the potential safety hazard of a pull rope winding around the neck is avoided, the structure is simple, the number of assembly parts is small, the assembly efficiency is higher, the problem that the pull rope is easy to knot and is easy to hook and break can be solved, smoother usage is achieved, and the overall structure is neater and cleaner.
