ROLLING CURTAIN
A rolling curtain is provided according to the present application, which includes a reel, a curtain body and a fixing frame. The curtain body is wound around the reel, and when the curtain body is in use, an outer end of the curtain body is hung vertically below the reel, and an inner end of the curtain body is connected with the reel. The reel is rotatable and has two rotation directions of winding and releasing. The fixing frame is connected with two ends of the reel. A control assembly is provided on at least one end of the reel. The control assembly includes at least one first elastic member. One end of the first elastic member is connected with the reel, and the other end of the first elastic member is connected with the fixing frame. The first elastic member is configured to drive the reel to rotate in the winding direction, and the force of the first elastic member for driving the rotation of the reel in the winding direction is balanced in real time with the force of the portion of the curtain body hung vertically below the reel for driving the rotation of the reel in the releasing direction. The curtain provided by the present embodiment can maintain balance with the help of gravity.
