intermittent gear turning mechanism with the blind of the pulley mechanism

摘要

The present invention relates to a blind, in particular, blind pulley system. The blind pulley mechanism with intermittent gear turning mechanism comprises a base and cover, base is provided with a pulley mechanism and intermittent gear turning mechanism, the ladder tape is wound on the pulley mechanism, the pulley mechanism is connected axially to the rotation mechanism, pulley mechanism and the intermittent gear turning mechanism is rotated by the square shaft. Pulley mechanism to control the horizontal lifting of sub-slat, and pulley in the interior of the pulley mechanism is rotated, it ladder tape is in or loosened wound to wound, to achieve a horizontal lifting of each sub-slat. When each sub slats horizontally rise to the default position, and to realize the rotation and rotation of all the slats of turning cylinder by intermittent gear turning mechanism.BACKGROUND 4
