Description

  The present invention relates to an oil tank drain screw for automobiles and motorcycles. Especially, once installed, even if the user opens and closes the drain port repeatedly due to the pressing structure attached to the tip, the screw thread collapses or falls off. The present invention relates to a pressure type oil discharge valve that does not cause a problem.

  Most mechanical devices such as automobiles or motorcycles are powered by engine or motor power. Furthermore, in order to ensure the smooth operation of the engine, an oil tank is installed in the mechanical device, and oil for providing lubrication of engine parts is injected into the oil tank. However, after the engine has been operating for a certain period of time, a slight amount of metal powder is mixed into the oil due to wear due to long-time operation of internal components. If such a metal powder accumulates in a certain amount, the oil will change and cause engine wear. And in order to avoid the occurrence of such a problem, the automobile or motorcycle must change the engine oil at regular intervals.

  Currently, most of this type of mechanical equipment seals the oil outlet of the oil tank 3 by combining a drain bolt 1 shown in FIG. 1 with a washer or a rubber ring 2. When the engine oil in the oil tank 3 is changed, it is not possible to work without removing the drain bolt 1 and the rubber ring 2. Further, after the oil change operation, the drain bolt 1 is passed through the rubber ring 2 to discharge the oil. It is necessary to tighten. However, what has become clear when actually used is that after repeatedly tightening and loosening the drain bolt 1 to the oil discharge port several times, the phenomenon that the screw thread 10 collapses due to wear is caused. As a result of the inability to tightly connect 1 and the oil outlet, an oil leakage phenomenon occurs, and the safety of use of the automobile or motorcycle is impaired.
