Description

TECHNICAL FIELD

[0001] The utility model belongs to window decoration product technical field, specifically related to a window decoration rope winding device. BACKGROUND

[0002] As common window decoration products, venetian blinds and honeycomb blinds (accordion blinds) have a wide range of applications in indoor decoration and light adjustment. In venetian blinds and honeycomb blinds, the hanging rope plays a key role.

[0003] For venetian blinds, the hanging rope is mainly used to adjust the angle of the blades and control the lifting of the blind. When adjusting the angle of the blades, the degree of inclination of the blades can be changed by pulling the hanging rope, thereby adjusting the angle and intensity of the light entering the room. In terms of lifting control, the hanging rope is wound around the reel, and by pulling or lowering the hanging rope, the venetian blind can be raised or lowered, making it convenient to open or close the blind according to the needs.

[0004] The hanging rope of the honeycomb blind is also used for lifting the blind. Due to the structural characteristics of the honeycomb blind, when the hanging rope is pulled up, the honeycomb structure is compressed and the blind is raised; when the hanging rope is lowered, the blind is lowered under the action of its own gravity and the elasticity of the honeycomb structure.

[0005] The rope winding device of the hanging rope is a key component for realizing the lifting function of the blind. The existing rope winding device basically has two types: one is to directly wind the hanging rope through a smooth winding drum, so that the position of the wound hanging rope remains basically unchanged, resulting in the wound rope being stacked together, increasing the outer diameter of the rope and making the levels chaotic, which can easily cause the rope to jam. The other is to add a lead screw and a guide piece, such as the window blind rope winding device and the venetian blind disclosed in CN202322385044, the guide piece moves along the lead screw, so that the guide piece rope can be gradually wound on the smooth winding drum, which can reduce the thickness of the stacked rope, but there is still a phenomenon of chaotic stacking.

[0006] In addition, the existing rope winding device needs to be threaded from the internal hole when threading the rope. Since the hole is inside the device, it is relatively hidden and has a small gap, making it very troublesome to thread the rope, time-consuming and reducing the production efficiency of threading the rope.

[0007] Therefore, it is necessary to continuously improve the technology, develop a rope winding device, improve the smoothness and regularity of the winding, and improve the efficiency of threading and assembling the rope. INVENTION CONTENTS
