Self-positioning lifting device and shutter
The invention provides a self-positioning lifting device which is suitable for a blind window, the blind window comprises a winding device and a plurality of blades which are uniformly distributed at equal intervals from top to bottom, a retractable lifting wire is arranged in the winding device, and the self-positioning lifting device comprises a resistance mechanism and an elastic positioning mechanism; when the blades are pulled downwards, the resistance mechanism can clamp the lifting line to form resistance for the blades to move downwards, and the resistance is smaller than the pulling force for pulling the blades so that the blades can be pulled. The blades are pushed upwards to enable the resistance mechanism to loosen the lifting line so that the blades can be folded upwards; and the elastic positioning mechanism is linked with the winding device, so that the blade can be positioned at any position. The invention further provides the shutter which is convenient to operate, the blades can be positioned at any position, and the blades at the two ends can be flatly aligned.
本发明提供了一种自定位升降装置，适用于百叶窗，百叶窗包括绕线装置以及由上至下均匀且等距分布的若干叶片，绕线装置内设置有能收放的升降线，自定位升降装置包括阻力机构和弹性定位机构；在往下拉动叶片时，阻力机构能够夹住升降线以形成叶片向下活动的阻力，阻力小于拉动叶片的拉力，以能拉动叶片；往上推动叶片以使阻力机构松开升降线以便于往上收叠叶片；弹性定位机构与绕线装置联动，能够使叶片能定位于任何位置上。本发明还提供了一种操作方便、能在任意位置定位叶片且两端叶片能平整对齐的百叶窗。
