The invention relates to the technical field of human body electrostatic discharge elimination, in particular to an intrinsically safe explosion-proof oil tank nozzle. The intrinsically safe explosion-proof oil tank nozzle is characterized by comprising an insulated oil injection pipeline; at least one group of elastic hinges 1 and a conductive baffle plate 1 connected to the elastic hinges 1 arearranged on the insulated oil injection pipeline; the conductive baffle plate 1 is connected with a normally-closed magnetic control switch 1 and a resistor R1 to the oil tank main body shell throughthe elastic hinges 1; the conductive baffle plate 1 keeps a state of blocking the oil injection pipeline under the elastic force of the elastic hinge 1; a permanent magnet is arranged on the conductive baffle plate 1; during refueling, a gun barrel of the refueling gun firstly collides with the conductive baffle plate 1, the conductive baffle plate 1 is driven by the gun barrel of the refueling gun to be opened and away from the normally-closed magnetic control switch 1 to be closed, and the refueling gun and the oil tank main body are electrically connected through the normally-closed magnetic control switch 1 and the resistor R1 to achieve safe electrostatic discharge. The intrinsically safe explosion-proof oil tank nozzle has the beneficial effect that electrostatic sparks can be avoided when an oil tank provided with the oil tank nozzle is filled with oil.
