A common torsion spring device for a double-pull car door lock

Abstract

This utility model relates to the field of car door lock technology, specifically a shared torsion spring device for a double-pull car door lock. It allows the unlocking block and ratchet to share a single torsion spring for reset, simplifying assembly. It includes a double-pull lock housing, within which an unlocking component and a ratchet are disposed. The ratchet is rotatably mounted on a ratchet shaft, and the unlocking component is slidably mounted in a guide groove. The unlocking component is characterized by a locking block, and a torsion spring is fitted onto the ratchet shaft, with one end of the torsion spring abutting against the ratchet and the other end abutting against the locking block.
