▎ 摘  要

NOVELTY - The utility model claims a graphene anti-corrosion spiral spike nail, comprising a spike rod body and a nut; the circumferential wall of the spike rod body and the spike rod body are coaxially fixed with a limiting ring; the circumferential wall of the spike rod body at the lower side of the limiting ring is provided with a first screw thread; the bottom end of the first screw thread is flush with the bottom end of the spike rod body; the top end and the bottom surface of the limiting ring is provided with a distance; the circumferential wall of the spike rod body on the upper side of the limiting ring is provided with a second screw thread; the spike rod body at the lower side of the second thread; the limiting ring; the spike rod body below the limiting ring and the outer surface of the first screw thread are static sprayed with anticorrosive coating composed of graphene anticorrosive powder coating; the nut is a hexagonal nut rotatably connected on the spike rod body on the upper side of the limiting ring; the inner screw thread on the inner wall of the nut is matched with the second screw thread. The utility model solves the problem that the spiral spike nail will be eroded by the rainwater or wet air to loosen the surface of the spiral spike nail and the nut on the spiral spike nail to loosen.
