A spring self-closing door hinge is a specialized hinge that automatically closes a door after it’s opened, using a built-in spring mechanism. Here’s a breakdown of key aspects:
How It Works:
Torsion Spring: A coil spring inside the hinge barrel is wound when the door opens.
Spring Rotation Tightens: Opening the door winds/tightens the spring via rotation to store energy.
Automatic Return: Releasing the door allows the spring to unwind, pulling the door smoothly back to the closed position. Turn the screw to adjust the spring-coil tightening force.
