Abstract

The invention provides a technical scheme of a ladder tape fixing device. The ladder tape fixing device comprises a fixed seat body and a sleeve. The sleeve is a hollow cylindrical body provided withopenings in two ends and two bulge groups are arranged in the peripheral direction of an outer wall; the two bulge groups are arranged in a staggered manner and a ladder tape is wound between the twobulge groups; each bulge group comprises at least two bulges; the fixed seat body is used for placing the sleeve; and the sleeve can rotate relative to the fixed seat body. The ladder tape fixing device for controlling a curtain to adjust light through folding or unfolding blades comprises the sleeve and the fixed seat body; the sleeve is used for a rotary shaft to penetrate; when a handle is rotated, the rotary shaft is driven to rotate and then the sleeve for the rotary shaft to penetrate is rotated to drive the two bulge groups to rotate, so that the ladder tape wound between the two bulgegroups is rotated along with the two bulge groups in the anticlockwise or clockwise direction, and furthermore, the blades are controlled to be folded or unfolded. The invention further provides the curtain.

Description

technical field [0001] The invention relates to the technical field of curtains, in particular to a ladder belt fixer. The invention also relates to a window covering comprising a ladder strap anchor. Background technique [0002] There are many forms of curtains at present, and the ways to adjust the height of curtains can be divided into drawstring type and drawstring type. The cordless method is to apply an upward or downward force to the bottom of the curtain by hand, causing the curtain to be stretched or folded. [0003] The cordless curtain mainly includes blades, ladder belts and a controller. The controller controls the retraction or deployment of the blades. As described in the patent CN202913926U venetian blind and the venetian blind control device, the controller includes a first part that drives the rotation of the winding transmission shaft of the venetian blind. A rotating part, and a second rotating part that drives the transmission of the first rotating pa...
