The opening of the oil inlet hole is arranged on the top side of the oil discharge rod.

An annular groove is provided on the inner wall of the through hole of the oil discharge screw plug, and a sealing ring is provided in the annular groove, and an interference fit is provided between the oil discharge rod and the sealing ring.

The oil discharge channel is located on the center line of the oil discharge mark rod.

The oil inlet holes are arranged on the top of the oil discharge pole and distributed evenly along the circumference.

An oil discharge control method utilizing the oil discharge tooling, comprising the following steps:

1) Move the oil discharge pole upward, and the oil enters the interior of the pole through the oil inlet hole at the top of the pole;

2) Drain the oil in the oil pan through the oil drain valve at the bottom of the oil drain pole, and measure the current liquid level in the oil pan through the size scale on the pole.

Compared with the prior art, the present invention has the following advantages:

The structure design of the oil discharge tool is reasonable, the height of the oil discharge liquid in the engine oil pan is controllable, and the height of the liquid level in the oil pan can be measured, which improves the consistency of oil sampling and the accuracy of physical and chemical results; and the structure of the tool is simple, Easy to use and low cost.

Detailed ways

The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

As shown in Figures 1 to 3, the oil discharge tool 2 is arranged at the bottom of the oil pan 1, which includes an oil discharge screw plug 5, an oil discharge rod 3 and an oil discharge valve 6, and the oil discharge screw plug is provided with a through hole , the oil discharge mark rod 3 can be moved up and down in the through hole of the oil discharge screw plug, the oil discharge mark rod 3 is provided with an oil discharge channel along the axial direction, and the top of the oil discharge mark rod 3 is provided with an oil inlet connected to the oil discharge channel. Hole A and the oil discharge valve 6 are arranged at the bottom of the oil discharge mark rod and connected with the oil discharge channel, and the outer surface of the oil discharge mark rod is provided with a scale C along the axial direction.

The height of the liquid level in the oil pan 1 can be measured through the dimensional scale on the outer surface of the oil discharge rod 3, and the height of the oil drain liquid level in the engine oil pan is controllable, which improves the consistency of oil sampling and the accuracy of physical and chemical results.

The oil drain plug 5 has a through hole, the inner wall of the through hole is provided with an annular groove B, and an O-ring 4 is assembled in the annular groove.
