Roller shutter driving device operated through pull rope
The present invention relates to a driving device for a roller blind, which rotates a drum (3) around which a roller blind cloth (2) is wound in the forward/reverse direction using only one pull cord (1) to raise or lower the roller blind cloth, and is characterized by comprising: a driving case (10) fixed to one side of the drum (3); a drive operation unit (20) that is rotatably mounted inside the drive case (10) and is connected to the pull cord (1) so as to be able to transmit only a forward rotational force generated by a pulling operation to a spool (3), and that winds around the pull cord (1) so as to return the pull cord (1) to a raised position; and a spool control unit (30) which is rotatably attached to the outside of the drive housing (10), receives the rotational force from the drive operation unit (20) to rotate the spool (3) in the forward direction, and fixes or rotates the spool (3) in the reverse direction at a point in time when the rotational force of the drive operation unit (20) is cut off. Therefore, the present invention has the following effects: the roller on which the roller shutter cloth is wound is rotated forward/backward with only one pull cord to raise or lower the roller shutter cloth, and the roller shutter cloth is returned to the raised position by winding the pull cord, thereby not only improving the convenience in use, but also improving the durability of the roller shutter cloth. And the safety accident that the pull rope is wound on the body due to the intention of the user or the unintention of the child can be prevented.
本发明涉及一种用于卷帘的驱动装置，仅用一根拉绳1将缠绕有卷帘布2的卷筒3以正向/反向旋转，使卷帘布上升或下降，其特征在于，包括：驱动壳10，固定设置在所述卷筒3的一侧；驱动操作部20，能够旋转地安装在所述驱动壳10的内部，且连接到所述拉绳1，从而能够向卷筒3只传递因拉动操作而产生的正向旋转力，并缠绕所述拉绳1，使其返回到上升的位置；卷筒控制部30，能够旋转地安装在所述驱动壳10的外部，接收来自于所述驱动操作部20的旋转力以正向旋转卷筒3，在所述驱动操作部20的旋转力切断的时间点，固定或者反向旋转卷筒3。因此，本发明具有如下效果：仅用一根拉绳将缠绕有卷帘布的卷筒以正向/反向旋转，使卷帘布上升或下降，而且通过缠绕拉绳，使其返回到上升的位置上，既提高了使用上的便利性，又能够防止因用户的有意或者孩子们的无意导致拉绳缠绕在身体的安全事故。
