Description

풀림방지형 체결부재{FASTENING MEMBER FOR PREVENTING FROM LOOSENING}Unfastening fastening member {FASTENING MEMBER FOR PREVENTING FROM LOOSENING}

본 고안은 체결볼트 또는 체결너트와 같은 체결부재에 관한 것으로, 더욱 상세하게는 체결부위에 가해지는 진동이나 충격 등에 의해 임의로 풀려지는 현상이 방지될 수 있어 체결력이 확고히 유지될 수 있도록 한 풀림방지형 체결부재에 관한 것이다.The present invention relates to a fastening member such as a fastening bolt or a fastening nut, and more particularly, the loosening prevention type that can be prevented to be released arbitrarily due to vibration or shock applied to the fastening portion to maintain the fastening force firmly It relates to a fastening member.

일반적으로 2개의 체결대상물을 간편하면서 견고하게 체결하는 데 있어서, 체결볼트만으로 이루어지거나 또는 체결볼트와 체결너트의 조합으로 이루어지는 체결부재가 사용되어 왔다.In general, in fastening two fastening objects simply and firmly, a fastening member made of only a fastening bolt or a combination of a fastening bolt and a fastening nut has been used.

통상적으로 체결볼트의 경우에는 볼트머리부의 하부에 일정한 피치를 가지는 나사산을 가지는 볼트부가 일체로 형성됨에 따라, 체결시 체결방향으로는 체결대상물의 체결공에 형성된 나사산과 밀착되지만, 그 반대방향으로는 백래쉬(Backlash)가 형성되면서 체결상태에서 유동이 발생할 수 있는 틈새가 형성되므로, 체결부위에 진동이나 충격이 가해질 경우에 임의로 풀려져 체결대상물의 체결상태가 해제되는 문제점이 있었다.In general, in the case of the fastening bolt, as the bolt part having a thread having a constant pitch is integrally formed at the lower part of the bolt head, the fastening direction during the fastening is in close contact with the thread formed in the fastening hole of the fastening object. Since a backlash is formed and a gap in which a flow may occur in a fastening state is formed, there is a problem in that the fastening state of the fastening object is released by being released at random when vibration or shock is applied to the fastening part.

이러한 문제점을 해결하기 위하여 체결볼트가 체결된 상태에서 풀림이 방지될 수 있도록 하는 풀림방지수단으로서, 스프링와셔가 개재되거나 별도의 고정용 핀을 체결볼트에 설치하는 구성이 사용되어 왔으나, 이러한 종래의 풀림방지수단의 경우에도 체결볼트의 풀림을 확실하게 방지하지 못할 뿐만 아니라, 오히려 부품 수가 증가하면서 체결공정이 더욱 불편하게 되는 점 등의 문제점이 있었다.In order to solve this problem, as a loosening preventing means for preventing the loosening in the fastening state of the fastening bolt is fastened, a spring washer or a configuration for installing a separate fixing pin to the fastening bolt has been used, but such a conventional In the case of the anti-loosening means, not only does not prevent the loosening of the fastening bolts securely, but also there is a problem such that the fastening process becomes more inconvenient as the number of parts increases.

따라서 본 고안의 목적은, 체결부위에 가해지는 진동이나 충격 등에 의해 임의로 풀려지는 현상이 방지될 수 있어 체결력이 확고히 유지될 수 있도록 한 풀림방지형 체결부재를 제공하는 것이다.Accordingly, an object of the present invention is to provide an anti-loosening fastening member that can be freely released by vibration or shock applied to a fastening part, so that the fastening force can be maintained firmly.
