Lead Springs Are The Core Components For Flexible Operation In Sunshade Systems, Mainly Used To Connect Sunshade Components Such As Sunshades And Blinds With Operating Mechanisms. They Transmit Traction Force Through Elastic Deformation To Ensure Smooth Retraction Of Sunshade Products. It Is Widely Used In Scenarios Such As Sunshades, Indoor Roller Blinds, And Outdoor Sunshades, And Is A Key Component In Improving The Convenience Of Using Sunshade Equipment.
Structurally, Lead Springs Are Typically Composed OfSpiral Spring BodyComposed Of Connecting Components At Both Ends. The Spring Body Is Mostly Made Of High Carbon Steel Or Stainless Steel Wire, With A Diameter Ranging From 0.5-2mm According To The Load-bearing Requirements. The Number Of Spiral Turns And Pitch Are Precisely Calculated To Ensure A Suitable Elastic Coefficient. The Connecting Parts At Both Ends Are Often Designed As Hooks, Rings, Or Flat Interfaces, Which Facilitate Stable Connection With Components Such As Sunshade Fabric Ropes And Operating Rods.
Its Working Principle Is Based On Hooke's Law. When Operating The Sunshade Device, The Lead Spring Stores Elastic Potential Energy By Stretching Or Contracting, Buffering External Force Impact And Avoiding The Rope From Breaking Due To Instantaneous Excessive Force. High Quality Lead Springs Have Good Fatigue Resistance And Can Withstand Tens Of Thousands Of Expansion And Contraction Cycles, Maintaining Stable Performance In The Temperature Range Of -30 ℃ To 70 ℃.
During Installation, Attention Should Be Paid To Adjusting The Pre Tension Of The Spring. If It Is Too Loose, It Will Cause The Sunshade Cloth To Sag, And If It Is Too Tight, It Will Accelerate The Aging Of The Spring. Regularly Cleaning The Dust And Foreign Objects On The Surface Of The Spring Can Effectively Extend Its Service Life.
