Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1 to Figure 10 As shown in , a loop-drawing type venetian blind includes a top beam 1, a bottom beam 2, a plurality of venetian blinds 3 arranged in sequence along the vertical direction, and the length direction of the venetian blinds is horizontal, and also includes a runner 4. The loop pull rope 5 that drives the runner to rotate, the self-locking structure 6 used to lock the runner, and a number of curtain control mechanisms 7, the curtain control mechanism includes a top frame 71 arranged on the top beam, a rotating shaft that can rotate relative to the top frame The shell 72, the rotating shaft 73 driven by the runner and the two vertical corner ladder belts 74 used to drive all the venetian blinds to rotate at the same time. Any venetian blind is between the top beam and the bottom beam. In the mechanism: any vene...

Abstract

The invention discloses a venetian blind with a circulating drawstring, which comprises a top beam, a bottom beam, a plurality of venetian blinds, a runner, a circulating drawcord, and a curtain control mechanism. There is a curtain-retracting rope that is connected to the rotating shaft at one end and can be wound on the rotating shaft. The upper end of the curtain-retracting rope is connected with the rotating shaft, and the lower end of the curtain-retracting rope is connected with the bottom beam. The threading holes are located between the two vertical corner ladder belts, and the curtain-retracting ropes pass through all the corresponding threading holes sequentially from top to bottom, and the diameter of the threading holes is larger than the outer diameter of the curtain-retracting ropes. The beneficial effects of the present invention are: reasonable structure, effective opening and closing, simple and quick operation, and the venetian blinds can be lifted as a whole to realize a large opening; effective compensation for shading, and better shading effect; automatic adjustment for closing the blinds Due to the function of the position of the rope, when the blinds are rolled up, there will be no intertwining and knotting between the coils of the rolled up curtain rope.

Description

technical field [0001] The invention belongs to the field of venetian blinds, in particular to a loop-drawing type venetian blind. Background technique [0002] Venetian blinds are a style of curtains, which are widely used in modern life. Traditional venetian blinds mainly include a plurality of venetian blinds and an adjustment structure for adjusting the angle of the venetian blinds. When the venetian blinds are in use, they can be opened or closed by adjusting the angle of the venetian blinds. When closed, the edges of adjacent venetian blinds overlap, which can have the effect of shading and blocking. When opened, the venetian blinds are parallel to each other. , There is a gap between adjacent venetian blinds, which can transmit light. Although the current blinds can be opened and closed normally, and have a blocking function, they are still lacking in the convenience of adjustment and the ability to open significantly. Contents of the invention [0003] The objec...
