Description

Technical Field

[0002] There are several styles of roller blinds on the market today, which are mainly installed in doors and windows of homes and offices to block sunlight and provide decoration. Most of the current roller blinds have spring assemblies installed in the roller blind rods to serve as a power component for winding or as a buffer component.

Springs of different specifications are adapted to curtains of a certain size range, and are pre-tightened and adjusted before being installed on the wall to adjust the springs to the required elastic force. However, this method of use will result in a larger span range of the springs and poor adjustment accuracy, resulting in the inability to achieve a better balance of force, which will affect the user experience of the roller blinds, and thus needs to be improved.
