또한, 상기 밸브(20)의 하부에 개재된 원형 코일스프링(40)의 탄성력에 의해 상기 밸브(20)가 상기 상부 바디(10a)에 밀착이 강화되어 오일의 누유가 방지된다.In addition, the valve 20 is strengthened by the elastic force of the circular coil spring 40 interposed below the valve 20 to the upper body 10a to prevent leakage of oil.
오일 교환시는 손잡이돌출부(32')가 형성된 상기 나비너트(32)를 돌리면 상기 피니언부재(31)의 피니언기어(31')가 회전되면서 이에 맞물려 있는 상기랙기어(20')가 회전되어 상기 랙기어(20')와 일체형을 이루는 상기 밸브(20)가 하강하여 상기 밸브(20)의 상부가 상기 상부 바디(10a)와의 밀착이 해제되어 상기 상부 바디(10a)의 유출구(b)를 통해 상기 오일팬(3)내의 오일이 외부로 유출된다.When the oil is replaced, when the butterfly nut 32 having the handle protrusion 32 'is turned, the pinion gear 31' of the pinion member 31 is rotated and the rack gear 20 'engaged with the pinion member 31 is rotated, The valve 20 which is integrated with the rack gear 20 'is lowered so that the upper part of the valve 20 is in close contact with the upper body 10a and is discharged through the outlet b of the upper body 10a. The oil in the oil pan 3 flows out.
오일 유출후 새 오일을 넣을 때는 상기와 반대로 하면된다.When adding new oil after oil spill, reverse the above.
이상과 같이 본 발명에 따른 오일 드래인 플러그 구조를 예시된 도면을 참조로 설명하였으나, 본 명세서에 개시된 실시예와 도면에 의해 본 발명은 한정되지 않으며 그 발명의 기술사상 범위내에서 당업자에 의해 다양한 변형이 이루어질 수 있음은 물론이다.As described above, the oil drain plug structure according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited by the embodiments and drawings disclosed herein, and various modifications may be made by those skilled in the art within the technical scope of the present invention. Of course, modifications can be made.
상기한 바와 같은 본 발명의 오일 드래인 플러그 구조는 오일 교환시 작업이 용이하고 별개의 공구를 사용하지 않고 손으로 작업이 가능한 장점이 있다.The oil drain plug structure of the present invention as described above has the advantage that it is easy to work during oil change and can be operated by hand without using a separate tool.
또한 오일 교환시 드래인 플러그를 오일팬에서 분리하지 않으므로 나사산 손상이 없고, 상기 드래인 플러그가 손상되더라도 교환이 가능한 장점이 있다.In addition, since the drain plug is not separated from the oil pan during oil change, there is no thread damage, and even if the drain plug is damaged, the exchange plug may be replaced.
아울러 오일 교환 작업시 손 또는 장갑에 오일이 묻을 염려가 없고, 상기 드래인 플러그의 분실 염려가 없는 장점이 있다.In addition, there is no fear of oil on hands or gloves during oil change operation, and there is no fear of losing the drain plug.
