Folding spring

Folding spring is a non helical elastic element formed by folding spring steel or elastic metal sheets. Its core features are bi-directional folding, high compression ratio, and adaptability to scenarios that require "shrink storage" or "narrow space support"; It mainly achieves buffering, support or rebound functions through the unfolding and shrinking of the folding structure, such as providing elastic support for folding furniture or achieving automatic reset for storage devices; Commonly found in folding sofas, folding beds, portable storage boxes, and other products, frequent over folding should be avoided during use to prevent metal fatigue from causing structural fracture and affecting elastic performance.
