Poll-cord control device for curtain without operating cord
A pull-cord control device for a curtain without an operating cord, comprising a base (1) and a press plate (2) which is pivotally connected to one end of the base (1) by means of a rotating shaft (42); the side of the base (1), facing toward the press plate (2), is provided with a first friction shaft (11); the side of the press plate (2), facing toward the base (1), is provided with a second friction shaft (21) which is arranged to be staggered with the first friction shaft (11); the end of the press plate (2), being set at a distance farther from the rotating shaft (42), is provided with a fixed rod (41); one end of a pull-cord (3) of a curtain is connected to a cord retracting and releasing device (5) of the curtain, and the other end of the pull-cord (30) passes through the first friction shaft (11) and the second friction shaft (21) and is connected to a curtain body (6) of the curtain after passing the fixed rod (41); when the curtain body (6) moves vertically, the press plate (2) is driven by the pull-cord (3) to rotate around the rotating shaft (42) between a clamping position and a released position relative to the base (1), and when the press plate (2) is positioned in the clamping position, the second friction shaft (21) enables the pull-cord (3) to wind around the first friction shaft (11) and the second friction shaft (21). By means of the pull-cord control device for a curtain without an operating cord, the height of a curtain can be freely adjusted, facilitating the raising and lowering of a curtain.
