Patent attributes
The application provides a hinge structure comprising a first connecting piece provided with a slot and a second connecting piece provided with a rotating shaft. An inner wall of the slot is provided with a limiting slot and an outer surface of the rotating shaft is convex to form a clipping strip; the clipping strip is inserted into the limiting slot to limit a relative rotation angle between the first connecting piece and the second connecting piece. The present application also provides a packaging box comprising the above hinge structure. The hinge structure and the packing box are provided with a limiting slot in the slot and a clipping strip on the rotating shaft. Through the cooperation between the clipping strip and the limiting slot, the relative rotation angle between the first connecting piece and the second connecting piece is fixed and the reliability of the hinge structure is improved.
