Core Structure and Working Principle
Stainless steel spring hinges incorporate a spring return mechanism based on traditional hinges (consisting of leaves and a pin). The core structure includes:
Stainless steel leaves: Designed in pairs, connected by a pin, they can rotate around an axis (usually opening and closing angles of 0° to 180°).
Spring assembly: Typically a coil or torsion spring, concealed within the leaf cavity, utilizes the spring's elastic potential energy to provide a rebound force.
Adjustment: Some models feature a screw adjustment mechanism that allows the spring to be tightened or loosened to control the rebound force (e.g., adjust the door closing speed).
Working Principle: When the door is pushed open, the spring is twisted or stretched, storing energy. When the force is released, the spring releases this energy, rotating the leaves and automatically returning the door to its original position.link:http://www.ytcqmetal.com
