A power adapter cable outlet structure

ActiveCN224279406UPull out quicklyfast windingControl theoryTorsion spring
This application discloses a power adapter cable outlet structure, relating to the field of power adapters. The adapter includes an adapter with a winding mechanism inside its cavity and a locking mechanism on one side. The winding mechanism includes a fixed rod fixedly installed inside the adapter, and a winding roller is provided on the outer surface of the fixed rod. This invention, through the action of the winding mechanism, can wind up the cable harness, facilitating the carrying of the adapter. Pulling the connector outward causes the cable harness to be released from the winding roller. After being pulled to the desired length, it is ready for use. During further pulling, the winding roller drives a circular plate to rotate outside the fixed rod, causing a torsion spring to twist. After use, because the torsion spring has been twisted and needs to return to its original position, the torsion spring drives the circular plate to rotate in the opposite direction, which in turn drives the winding roller to rotate, thereby winding up the cable harness. This design facilitates quick pulling out and winding of the cable harness.
