Description

Curtain lifting device

The invention relates to a cordless curtain structure, in particular to a curtain lifting device capable of double opening and dimming.

According to the prior art, there is a curtain structure, such as a curtain that can be automatically raised in the national patent publication No. I229717, which includes: a frame in which a first pulley, a second pulley, a first guide wheel and a second guide are arranged A wheel is provided with a shielding object at the bottom end of the frame, and a bottom frame is provided at the bottom end of the shielding object; a control device is provided with a combination frame and arranged in the frame. The combination frame forms an accommodating space, and the first reel is pivoted in the accommodating space And the second reel. The first reel and the second reel are provided with a perforated shaft tube. Both ends of the shaft tube are formed with an upper sealing plate and a lower sealing plate. The upper side is divided into a slot, and the lower side is a ring groove. The first and second reels are equipped with threading ropes. The threading is a double row of two lines side by side. The rope is passed through the combination frame and wound Any line of the first pulley, the first guide wheel, the second guide wheel, and the second pulley, and the double-row cable can pass through the first guide wheel and the second guide wheel, and then pass through the frame and penetrate downwards. The object and the bottom frame are shielded, and the end of any line is fixed to the bottom end of the bottom frame with a fixing member; a reversible spring, which forms an S shape, has a first roll part and a second roll part that can be surrounded, and the first roll part is positioned It is wound in the ring groove of the first wire wheel, and the second coil is positioned and wound in the ring groove of the second wire wheel.
