Abstract

The technical scheme of a ladder belt fixer in the present invention includes: a fixing seat body and a sleeve; the sleeve is a hollow cylindrical body with two ends open, and two sets of protrusions are arranged on the outer wall circumferentially, and the two sets of protrusions are The set is misplaced and there is a ladder belt between them, and each of the protrusion groups includes at least two protrusions; the fixing base body is used to place the sleeve, and the sleeve is relatively to the fixing base body can be rotated. Because the ladder belt holder for controlling the dimming of the curtains in this embodiment, that is, the retraction or deployment of the blades, includes a sleeve and a holder body, the sleeve is used to pass through the rotating shaft, and when the handle is turned to drive the rotating shaft to rotate, then the rotating shaft passes through The sleeve rotates, and then drives the two protrusion groups to rotate, so that the ladder belt passing around between the two protrusion groups will rotate counterclockwise or clockwise, thereby controlling the retraction or deployment of the blades. The invention also provides a 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...
