Floor type direct-current charging pile for new energy automobile

The invention relates to the technical field of charging piles, and particularly relates to a floor type direct-current charging pile for a new energy automobile. The charging pile comprises a charging gun, a cable, a rotating plate, ratchets, a hinge rod, a sliding ring, an annular electromagnet and a pressure spring. The charging pile has the beneficial effects that during charging, the slidingring is abutted against by the pressure spring, so that the sliding ring slides in the direction of a rotating rod, the hinge rod drives the rotating plate to rotate until the inclined surface of therotating plate abuts against the inner wall of a outer automobile socket, the ratchets are enabled to abut against the inner wall of the socket, and at the moment, the charging gun cannot be pulled out of the socket, so that the protection of the charging gun is realized; the annular electromagnet is electrified to generate magnetism, so that the sliding ring slides in the direction of the annularelectromagnet, so that the
