Automatic oiling device of electric lubricating pump

The utility model belongs to the technical field of electric lubricating pump devices, and particularly relates to an automatic oiling device of an electric lubricating pump, which comprises an oil storage tank, an electric lubricating pump body is mounted on the upper surface of the oil storage tank, and a liquid pumping end of the electric lubricating pump body is communicated with one end of an oil pumping pipe. The liquid discharging end of the electric lubricating pump body communicates with one end of the oil conveying pipe, a buoy a, a connecting rod and a transparent graduated scale a are arranged, the buoy a is driven by buoyancy generated by rising or falling of oil in an oil storage tank to move upwards or downwards, and the buoy a moves to drive the connecting rod a to move in the same direction; people detect the amount of oil contained in the oil storage tank according to the up-and-down fluctuation of the buoy a, and observe the position of the connecting rod a through the transparent graduated
