Description

Technical Field

[0001] The utility model relates to the technical field of window rolling curtains, in particular to a driving component of an energy-saving rolling curtain mechanism. Background Art

[0002] The roller shutter mechanism in a hollow glass window is generally fixed between the two sides of the glass. The traditional built-in roller shutter drive mechanism is driven by a pull rope. The pull rope is ring-shaped, the upper end of the pull rope is connected to the reel, and the lower end of the pull rope is connected to the roller. The roller fixing block is fixed to the inner side of the window side frame by fasteners.

[0003] However, the roller fixing block at the lower end of the pull rope is fixed by a fastener, which makes the installation of the roller fixing block troublesome. At the same time, the roller fixing block is subjected to the tension of the pull rope. Long-term use will cause the fastener to loosen, thereby affecting the tension of the pull rope and the coordination with the roller, which will further cause the pull rope to jump. Therefore, in order to increase the tension of the pull rope and reduce the occurrence of pull rope jumping, the drive component of the energy-saving roller shutter mechanism is designed.
