Abstract
The invention relates to a leak-proof self-sealing oil filling gun, which comprises a gun body, a handle assembly, a main valve, a control valve and an oil outlet pipe; and an automatic opening-closing device is arranged inside an oil outlet passage of the oil outlet pipe, close to an oil outlet, the automatic opening-closing device consists of a helical spring and a steel ball, the front part of the helical spring adopts a conical structural spring, the rear end of the helical spring is fixedly installed on the inner wall of an oil outlet pipe oil outlet passage, and the inner side of a conical part of the helical spring is provided with the steel ball. When the main valve is opened for filling oil, the oil medium pressure pushes the helical spring to be stretched, and oil passes through a space between two helical spring coils; and when the main valve is closed, the helical spring is retracted to form a check valve structure with the steel ball so as to prevent the oil from dropping to the ground when the oil filling gun is unplugged. The leak-proof self-sealing oil filling gun has the advantages of high oil filling precision, low oil consumption and less environmental pollution and is applicable to an oil filling gun on a filling station filling machine.
