The invention provides a pull rope lock for blinds, and relates to the technical field of shutters. The pull rope lock comprises a housing, a rotating wheel and an adjusting rod, wherein the housing is of an inverted U-shaped structure; through strip-shaped groove holes are formed in the two side faces of the housing; a through groove opening is formed in the top surface of the housing; the rotating wheel is arranged between the two side faces of the housing and can freely rotate; the adjusting rod is arranged in the strip-shaped groove holes in a penetrating mode, and the adjusting rod can freely slide down in the strip-shaped groove holes under the action of gravity; and in the process that the adjusting rod freely slides down in the strip-shaped groove holes, at least one position of the strip-shaped groove holes can enable the adjusting rod to be tangent to the rotating wheel, the adjusting rod is arranged in the strip-shaped groove holes, one end of a pull rope is pulled, so thatthe drooping height of the blinds can be conveniently and randomly adjusted, and when the adjusting rod is tangent to the rotating wheel, the pull rope can be quickly locked; and the other end of thepull rope is pulled to enable the adjusting rod to be separated from the rotating wheel, the height of the blinds can be continuously adjusted, the operation is convenient, and time and labor are saved.
一种百叶帘用的拉绳锁具，涉及到百叶窗技术领域，包括壳体、转轮和调节杆，所述壳体呈倒置的“U”型结构，所述壳体两侧面设有贯通的条形槽孔，壳体顶面设有贯穿的槽口；所述转轮设置在壳体两侧面之间且能自由转动；所述调节杆穿设于条形槽孔内，所述调节杆在重力作用下能条形槽孔内自由滑落；调节杆在条形槽孔内自由滑落过程中，条形槽孔至少有一处能使调节杆与转轮相切，通过将调节杆设在条形槽孔内，拉动拉绳一端，方便任意调节百叶帘的下垂高度，在调节杆与转轮相切时，实现对拉绳的快速锁紧；且拉动拉绳另一端就能使调节杆与转轮分离，可以继续调节百叶帘的高度，操作方便，省时省力。
