본 고안은 도어 클로우저, 플로어힌지등 각종 유압기기에 사용되는 누유방지용 오링(O-Ring)에 관한 것으로, 특히 회전축과 축수에 접촉되는 오링의 내, 외주면에 수개의 원호형 돌조를 형성하여 오링의 누유방지 효과를 증가시키고 사용수명을 연장할 수 있게한 도어 클로우저의 누유방지용 오링에 관한 것이다.The present invention relates to a leak-proof O-ring used in various hydraulic equipment such as door closers and floor hinges, and in particular, several circular arcs are formed on the inner and outer circumferential surfaces of the O-ring in contact with the rotating shaft and the bearing. The present invention relates to an o-ring for preventing leakage of a door closer, which can increase the leakage prevention effect of the door and extend its service life.

종래의 원형 단면으로 된 오링은 회전축과 접촉되는 면이 단일면을 이루고 있기 때문에 그 접촉면이 마모되거나 기름과의 접촉으로 경화되면 적절한 압착상태를 유지할 수 없으므로 누유방지 효과가 좋지 못하고 따라서 사용수명이 짧은 결점이 있었다.The O-ring of the conventional circular cross-section has a single surface in contact with the rotating shaft, so if the contact surface is worn or hardened by contact with oil, it cannot maintain proper crimping condition, so that the oil leakage prevention effect is not good and the service life is short. There was a flaw.

본 고안은 이와같은 결점을 보완하기 위해 고무오링의 내주면 또는 내주면과 외주면에 수개의 원호형의 돌조와 골을 환상으로 형성하여 회전축과의 접촉면이 복수개로 형성되도록 함으로써 누유방지를 효과적으로 하고 사용수명을 연장할 수 있게한 것으로, 이와같은 본 고안을 도어 클로우저에 적용한 일 실시예를 도면에 의해 상세히 설명하면 다음과 같다.The present invention effectively prevents leakage and improves service life by forming a plurality of arc-shaped protrusions and valleys on the inner circumferential surface or inner circumferential surface and outer circumferential surface of the rubber O-ring to form a plurality of contact surfaces with the rotating shaft. In order to be extended, one embodiment of applying the present invention to the door closer will be described in detail with reference to the accompanying drawings.

도면에 도시한 바와같이 도어클로우저(1)의 축수너트(2)와 회전축(3) 사이에 삽입되는 고무오링(4)을 대략 사각형의 단면으로 구성함에 있어서, 오링(4)의 내주면 및 외주면에 호형돌조(4a)(4b)(4c) 및 (4a')(4b')(4c')를 각각 둘레를 따라 환상으로 돌설하고, 그 돌조들의 사이 사이에 호형골(4d)(4e) 및 (4d')(4e')을 각각의 둘레를 따라 환상으로 형성한 것으로, 도면주 미설명 부호 1a는 도어클로우저의 본체이고, 1b는 축수너트(2)의 체결공, 2a는 축수부시이며, 2b는 축수너트(2)에 축수부시(2a)가 삽입되어 이루어진 오링 삽입홈이다.As shown in the figure, the rubber o-ring 4 inserted between the shaft nut 2 and the rotation shaft 3 of the door closer 1 has a substantially rectangular cross section. Arcuate protrusions 4a, 4b, 4c, and 4a ', 4b', 4c ', respectively, annularly protrude along the circumference, and arcuate bones 4d, 4e, and between the protrusions. (4d ') (4e') is formed in an annular shape along each circumference, reference numeral 1a is a main body of the door closer, 1b is a fastening hole of the bearing nut 2, 2a is a bearing bush, 2b is an o-ring insertion groove formed by inserting the bearing bush 2a into the bearing nut 2.

이와같은 본 고안의 작용효과는 다음과 같다. 제3도 및 제4도에 도시한 바와같이 본 고안의 오링(4)을 오링 삽입홈(2b)에 삽입시킨 축수너트(2)를 회전축(3)의 일측부가 끼워지도록 축수 체결공(1b)에 결합시키면 오링(4)의 내, 외주면에 돌설된 호형돌조(4a)(4b)(4c) 및 (4a')(4b')(4c') 들의 회전축(3)의 외주면과 삽입홈(2b)의 내면에 긴밀히 압착되면서 그 호형돌조들은 제4도에 화살표로 도시한 바와같이 내, 외 주면의 호형골(4d)(4e) 및 (4d')(4e')쪽으로 팽창하게 된다. 따라서 이와같은 본 고안 오링(4)은 다수개의 호형돌조(4a)(4b)(4c), (4a')(4b')(4c')들이 회전축(3) 외주면과 축수너트(2) 내주면에 호형골(4d)(4e),(4d')(4e')을 사이에 두고 격리되어 압착되고 있기 때문에 종래의 원형 단면으로 된 오링(4)에 비하여 회전축(3)과의 접촉면이 크게 늘고 또한 구조상 오링(4)의 내측에 돌설된 호형돌조(4a)(4a')가 기름과의 장기간 접촉으로 인해 경화되어 누유방지력이 떨어지게 되더라도 가운데와 외측의 호형돌조(4b)(4b'), (4c)(4c')에 의해서 누유방지 기능이 이루어지고, 또한 내측 호형돌조(4a)(4a')와 가운데 호형돌조(4b)(4b')가 모두 경화되어 누유방지력이 떨어지더라도 외측의 호형돌조(4c)(4c')에 의해서 누유방지 기능을 계속 갖게 되므로 마치 원형단면의 오링을 복수개 설치한 것과 같은 누유방지 효과를 기대할 수 있으며, 장기간 사용으로 인해 오링(4)의 호형돌조( 4a)(4b)(4c), (4a')(4b')(4c')들이 마모되면 호형골(4d)(4e), (4d')(4e')쪽으로 압축되어 있던 부분들이 다시 팽창되어 회전축(3)의 외주면과 축수너트(2) 내주면에 대한 접촉상태를 양호하게 하므로 사용수명이 연장되는 이점이 있다.The effect of the present invention is as follows. As shown in FIG. 3 and FIG. 4, the bearing fastening hole 1b is fitted so that one side of the rotating shaft 3 is fitted with the bearing nut 2 into which the O-ring 4 of the present invention is inserted into the O-ring insertion groove 2b. When coupled to the outer peripheral surface and the insertion groove (2b) of the rotating shaft (3) of the arc-shaped protrusion (4a) (4b) (4c) and (4a ') (4b') (4c ') protruding on the inner and outer peripheral surface of the O-ring (4) Tightly pressed to the inner surface of the) the arc bulge is expanded toward the arc (4d) (4d) and (4d ') (4e') of the inner and outer peripheral surface, as shown by the arrow in FIG. Therefore, this invention O-ring 4 has a plurality of arc-shaped protrusions (4a) (4b) (4c), (4a ') (4b') (4c ') on the outer peripheral surface of the rotary shaft 3 and the inner peripheral surface of the shaft nut (2) Since the arc-shaped bones 4d, 4e, and 4d 'and 4e' are separated and compressed, the contact surface with the rotary shaft 3 increases considerably compared to the conventional O-ring 4 having a circular cross section. Structural arc protrusions 4a, 4a 'protruding inside the O-ring 4 are hardened due to prolonged contact with oil, so that the oil leakage resistance is lowered. 4c) (4c ') prevents leakage of oil, and also the inner arc protrusions 4a (4a') and the center arc protrusions 4b (4b ') are hardened to prevent leakage. Leakage prevention function continues to be provided by the protrusions 4c and 4c ', so it is possible to expect a leak prevention effect as if a plurality of O-rings in a circular section are installed. Due to the wear of the arc protrusions 4a, 4b, 4c, 4a ', 4b' and 4c 'of the O-ring 4, the arcs 4d and 4e and 4e' The compressed parts are expanded again to improve the contact state between the outer circumferential surface of the rotating shaft 3 and the inner circumferential surface of the shaft nut 2, thereby extending the service life.
