Title: DUAL-PURPOSE HYDRAULIC ELECTRIC JACK
Abstract:
A dual-purpose hydraulic electric jack comprises a hydraulic lifting mechanism (1, 2), an oil pump (12), an oil tank (9), an oil conveying pipeline and an electric motor (14). The lifting mechanism, the oil pump and the oil tank are all connected with the oil conveying pipeline. A transmission mechanism is arranged between the oil pump and the electric motor. A one-way valve (10) is provided between the oil tank and the oil pump. The oil pump (12) is equipped on one end side of the electric motor (14), and an air pump (15) is equipped on the other end side of the electric motor (14). A transmission mechanism is arranged between the air pump and the electric motor. The air pump is communicated with an air conveying pipeline (35) and the electric motor is equipped with a trigger mechanism for controlling the connection of the electric motor with the transmission mechanism between the electric motor and the air pump or oil pump. The function of the hydraulic electric jack is enhanced greatly and the hydraulic electric jack is convenient to use.
