Sell Variable Force Springs For Cordless Curtains

Description

Variable Force Spring 



Feature: 



Variable force spring and variable torque spring are very similar with constant force spring and constant torque spring. Variable force springs and variable torsion springs can break through the influence of Hooke's law on traditional springs, so that stroke and force no longer increase proportionally, but can achieve various elastic force-displacement combinations such as negative slope stepped constant force, which can be mechanically controlled. For engineering requirements, use the relationship between elastic force and displacement stroke to design various elastic curve changes in specific applications. There are many different variable force springs designed available for any given application to meet customized solutions.



Application:



Variable force springs and variable torsion springs can be customized for various elastic curve changes according to specific applications,such as automotive seat belts, store shelf propelling devices,pen-type drug syringe (insulin), cordless curtains.



The variable torque spring can be applied to cordless shade, it makes user to adjust curtain up and down easily. The spring exerts smaller torque step by step, which generate balance of gravity to allow the curtain to stop at any height.
