Movable insulating ladder

The utility model discloses a movable insulating ladder. Top plate, the bottom of the top plate is hinged with supporting legs which are opened into herringbone shapes; horizontal pedals are hinged tothe side surfaces of the supporting legs; one end of the horizontal pedal is fixedly connected with a vertically-downward supporting rod. The tail ends of the supporting rods are flush with the ground. A lock catch is arranged on the corresponding side surface of the support leg on the other side; the lock catch locks the other end of the horizontal pedal; the other end of the horizontal pedal isfixedly connected with a spring; the other end of the spring is fixed on the bottom surface of the top plate; the bottoms of the supporting legs are fixedly connected with directional pulleys; horizontal pedal stepped by foot, the supporting rods in contact with the ground push the whole ladder to move forwards in opposite directions; the principle that friction force is used for providing powerwhen a person walks is simu
