CURTAIN ROD STRUCTURE FOR ELECTRIC CURTAIN

WIPO Patent Application WO/2023/213076

A1

A curtain rod structure for an electric curtain. The curtain rod structure comprises a curtain rod body (1), wherein curtain hanging rings (2) are sleeved on the outside of the curtain rod body (1) in an unfixed manner; the curtain rod body (1) is of a hollow pipe shape; a top part of the curtain rod body (1) is provided with a belt groove (3) and two limiting holes (4) along the direction of the rod body; the limiting holes (4) are located at two ends of the curtain rod body (1); the limiting holes (4) are located in the belt groove (3); belt pulleys (5) are arranged inside the curtain rod body (1); two belt pulleys (5) are connected to each other by means of a belt (6); the belt (6) passes through the limiting holes (4); a top part of the belt (6) is higher than the curtain rod body (1); and the belt pulleys (5) are connected to the curtain rod body (1) by means of pulley shafts (7). The advantages thereof lie in: the structure is simple, the installation is convenient, and belt pulleys (5) drive the rotation of a belt (6), thus realizing the operation of an electric curtain; in special circumstances such as a fault or a power cut, since a top part of the belt (6) is smooth and is not locked with curtain hanging rings (2), manual drawing of the curtain can be realized; and opening/closing modes of the curtain can be flexibly switched.
