Special-Shaped Frame-Leg Zinc-Plated Torsion Spring
Features an asymmetric design with a single straight leg on one end and a triangular frame leg on the other, combining torque output with structural positioning for precise return and force transmission in complex assembly scenarios.
Integrally cold-formed from high-quality carbon steel wire with no welded joints for uniform strength throughout. The single straight-leg end inserts onto a fixed pivot pin, while the triangular frame-leg end creates a surface contact rather than point contact with the force-receiving component, significantly reducing stress concentration risk and improving reliability and durability under high-torque conditions. Zinc plating provides solid corrosion resistance for outdoor or humid environments. The full arm geometry is customizable to fit various complex mechanism installation requirements.
Asymmetric special-shaped arm design (single straight leg + triangular frame leg) combining positioning and force transmission functions.
Triangular frame leg creates surface contact to effectively reduce localized stress concentration and extend service life.
Integrally cold-formed with no weld joints for high overall strength and reliability.
Zinc plating for corrosion resistance in outdoor and humid environments.
Tightly wound coil body for stable linear torque output; left-hand or right-hand winding available.
Arm shape, arm length, wire diameter, and opening angle fully customizable per technical drawings.
Application areas: Industrial equipment pedal return mechanisms / Motorcycle brake system linkage arms / Agricultural machinery control levers / Construction vehicle control handle return / Heavy-duty hardware tool opening and closing mechanisms
