Abstract

본 발명은 엔진의 오일 드레인 플러그에 관한 것이다.The present invention relates to an oil drain plug of an engine.

오일 팬(1)의 저면에 부착된 오일 드레인 보스(11)에 체결되는 엔진의 오일 드레인 플러그(15)에 있어서, 수나사부(16)와 머리부(17)를 가지며, 상기 머리부(17)에서 상기 수나사부(16)의 단부에 인접한 부분까지 축선방향 연장하는 수직 배출 통로(18)와, 상기 수나사부(16)에서 상기 수직 통로(18)에 수직하게 교차하여 서로 연이어 통하는 수평 배출통로(19)가 형성되어 있다. 상기 보스(11)의 수평 배출홀(14)과 상기 플러그(15)의 수평 통로(19)가 일직선 정렬하도록 상기 드레인 플러그(15)를 소정량 만큼만 풀면 상기 오일 팬(1)의 내부가 상기 보스(11)의 수평 배출홀(14), 상기 플러그(15)의 수평 통로(19), 및 그 수직 통로(18)를 통해 외부와 소통되므로써 엔진 오일이 배출된다.An oil drain plug 15 of an engine to be fastened to an oil drain boss 11 attached to a bottom surface of an oil pan 1 has a male threaded portion 16 and a head portion 17, A vertical discharge passage 18 extending in the axial direction from the discharge passage 18 to a portion adjacent to the end of the male screw portion 16 and a horizontal discharge passage 18 vertically crossing the vertical passage 18 in the male screw portion 16, 19 are formed. When the drain plug 15 is loosened only a predetermined amount so that the horizontal discharge hole 14 of the boss 11 and the horizontal passage 19 of the plug 15 are aligned with each other, The horizontal discharge hole 14 of the plug 11, the horizontal passage 19 of the plug 15 and the vertical passage 18 communicate with the outside to discharge the engine oil.

이에 따라, 오일 드레인 플러그를 완전히 분리시키지 않고도 오일을 배출할 수 있으므로 오일 드레인 플러그의 분실 우려가 없으며 엔진 오일의 배출 작업이 용이한 이점이 있다.Thus, since the oil can be discharged without completely separating the oil drain plug, there is no fear of losing the oil drain plug and there is an advantage that the discharge operation of the engine oil is facilitated.
