Gravity pendulum type supporting leg for vehicle-mounted hydraulic tail plate

The invention discloses a gravity pendulum type supporting leg for a vehicle-mounted hydraulic tail plate, which is arranged on the hydraulic tail plate. A locker is arranged on the hydraulic tail plate; the gravity pendulum type supporting leg for the vehicle-mounted hydraulic tail plate comprises a supporting leg, a rotating shaft, a vertical limiting plate and a hinged support; the hinged support is fixed on the hydraulic tail plate; the vertical limiting plate is vertically fixed on the hinged support; the rotating shaft is fixed between the hinged support and the supporting leg; one end of the supporting leg sleeves the rotating shaft; and the supporting leg is in close contact with the vertical limiting plate. The supporting leg comprises a supporting leg housing, a screw and a driving mechanism, wherein the screw is connected with the driving mechanism; a travel switch is mounted on the screw; and a locking mechanism is arranged between the supporting leg housing and the hinged support. Through the adoption of the method, the gravity pendulum type supporting leg for the vehicle-mounted hydraulic tail plate, disclosed by the invention, can be convenient for personnel to operate and has the advantages of simple structure, high reliability and strong university.
