Problems solved by technology

Restricted by the structure of the positioning device, when positioning, the drum often needs to be rewound about half a circle before stopping. Therefore, when people need to accurately control the release length of the curtain cloth or the rope for retracting and retracting the curtain, they first need to know the rotation positioning of the drum. Then, according to the rewinding during positioning, the corresponding length should be lengthened in advance. However, since users generally do not have this knowledge, it will bring great inconvenience to users.

Abstract

A single pull rope driving device for a window curtain includes a bracket (1), a reeling drum (2) mounted to the bracket (1), a pull rope (12) for driving the reeling drum (2) to rotate, a gear (7) coupled to the reeling drum (2), a pivotable toothed bar (8) pivotably mounted beside the gear (7), and a spring (11) connected to the pivotable toothed bar (8). The pivotable toothed bar (8) includes a lever (9) with teeth (10). The teeth (10) of the pivotable toothed bar (8) can be engaged with teeth (7a) of the gear (7), preventing rotation of the reeling drum (2). The reeling drum (2) can be driven by moving the pull rope (12) to overcome the spring (11) and to disengage the teeth (10) of the lever (9) from the teeth (7a) of the gear (7).

Description

technical field [0001] The present invention relates to a curtain member. Background technique [0002] The existing technologies for driving curtain retraction by pull cords (as disclosed in Chinese patents 200910041288.6, 200810027859.6, and 200810027849.2) include a single pull cord type rotating drive device for driving the reel, retractable curtain cloth or retractable and connected curtains. Rope reels, curtain fabrics, or positioning devices for cords attached to curtains, such as Figure 9 Shown, the rotation driving device 3 of single stay cord type is by the stay cord turntable box 3a that is fixed on the curtain support 1, the stay cord turntable 3c that the rotation is arranged in the stay cord turntable box 3a that is wound with stay cord 12, and pulls The one-way clutch device 6 that the rope turntable 3c is connected together constitutes, and the retraction spring 3e is arranged between the stay cord turntable 3c and the stay cord turntable box 3a, and the one...
