본 발명은 체결부재와 피 체결부재를 볼트로 견고하게 체결할 수 있도록 하는 볼트체결구조에 관한 것으로, 더 자세하게는 볼트를 통해 체결부재와 피 체결부재의 체결을 완료한 상태에서 볼트 체결부위에 가해지는 진동 등에 의해 볼트가 풀려 체결상태가 나빠지게 되는 현상을 방지할 수 있도록 한 볼트의 풀림을 방지할 수 있는 볼트체결구조에 관한 것이다.The present invention relates to a bolt fastening structure that allows the fastening member and the fastened member to be firmly fastened with bolts, and more particularly, is applied to the bolt fastening portion in a state where the fastening member and the fastened member are fastened through the bolt. The present invention relates to a bolt fastening structure that can prevent loosening of a bolt so as to prevent the bolt from being loosened due to losing vibration and the fastening state of the screw being worsened.

일반적으로 체결부재와 피 체결부재를 볼트로 체결하는 볼트체결구조는 머리부와 수나사부로 이루어지는 볼트와, 볼트 수나사부가 관통되는 관통구멍을 갖는 체결부재와, 체결부재의 관통구멍을 관통한 볼트 수나사부가 체결되는 암나사구멍이 형성된 피 체결부재로 구성되는 것이 보통인 바, 이러한 일반적인 볼트체결구조를 통해 체결부재와 피 체결부재를 체결하게 되면 볼트 체결부위에 진동이나 충격이 가해지는 경우 볼트가 풀리게 되어 체결상태가 나빠지게 되는 문제가 있게 된다.In general, the bolt fastening structure for fastening the fastening member and the fastened member with a bolt includes a bolt having a head and a male thread portion, a fastening member having a through hole through which the bolt male thread portion passes, and a bolt male thread portion passing through the through hole of the fastening member. It is usually composed of a fastening member having a female threaded hole to be fastened. When the fastening member and the fastening member are fastened through such a general bolt fastening structure, the bolt is loosened when vibration or shock is applied to the bolt fastening portion. There is a problem that the condition worsens.

이에 종래에 있어서도 피 체결부재에 결합되는 볼트의 풀림을 방지할 수 있도록 하는 다수의 볼트체결구조가 제안되었던 바, 종래의 것들은 대체적으로 볼트의 풀림을 확실하게 방지할 수 없었을 뿐 아니라 체결부재를 피 체결부재로부터 분리할 필요가 있을 때에 볼트를 빼내기가 매우 어렵게 되는 등의 문제가 있었다.Therefore, in the related art, a number of bolted fastening structures have been proposed to prevent the bolts from being loosely coupled to the fastening member, and the conventional ones have not been able to reliably prevent the bolts from loosening, as well as avoid the fastening member. When it is necessary to separate from the fastening member, there is a problem such that it becomes very difficult to remove the bolt.

그 대표적인 예를 들면 종래에 있어서는 실용신안등록 제186774호와 같이 볼트 머리부 하단면과 와샤의 상부면에 상보적으로 치합되는 환형 톱니부를 형성하는 동시에 와샤의 하단면에 체결부재의 상부면에 밀착되는 앵커돌기를 마련한 것이 제 안되었던 바, 이 종래의 볼트의 풀림을 방지할 수 있는 볼트체결구조는 실제적으로 체결부재의 상부면에 밀착되는 와셔의 앵커돌기에 의해 볼트의 풀림이 방지되는 것이므로 체결부재와 앵커돌기의 밀착력보다 큰 진동이나 충격이 가해지게 되면 볼트와 와셔가 동시에 회전하게 되면서 볼트가 풀리게 되는 문제가 있었고, 볼트의 환형 톱니부와 와셔의 환형 톱니부가 치합되어 있어 볼트를 풀리는 방향으로 회전시킬 수가 없게 되기 때문에 볼트의 풀림 없이 비교적 안정적인 체결상태가 유지되고 있는 상태에서는 체결부재를 피 체결부재로부터 분리할 수가 없게 되는 문제가 있었다.For example, in the related art, as in Utility Model Registration No. 186774, an annular tooth portion that is complementarily engaged with the lower surface of the bolt head and the upper surface of the washer is formed, and the lower surface of the washer is closely adhered to the upper surface of the fastening member. It was proposed to provide an anchor projection, which is a bolt fastening structure that can prevent the loosening of the conventional bolt is actually prevented from loosening the bolt by the anchor projection of the washer in close contact with the upper surface of the fastening member. When vibration or shock is applied to the member and anchor protrusion, the bolt and washer are rotated at the same time, causing the bolt to loosen, and the annular teeth of the bolt and the annular teeth of the washer are engaged so as to loosen the bolt. Since it cannot be rotated, it is possible to maintain a relatively stable tightening state without loosening the bolts. There has been a problem that the fastening member cannot be separated from the fastening member.

본 발명은 상기 종래 구조의 문제점을 감안하여 안출한 것이며, 그 목적이 볼트를 통해 체결부재와 피 체결부재가 체결된 상태에서 볼트의 체결부위에 진동이나 충격이 가해지더라도 볼트의 풀림 없이 안정적인 체결상태를 유지할 수 있도록 함은 물론 필요에 따라 볼트를 풀고 체결부재와 피 체결부재를 분리할 수 있도록 하는 볼트의 풀림을 방지할 수 있는 볼트체결구조를 제공하는 데에 있는 것이다.The present invention has been made in view of the problems of the conventional structure, the purpose is a stable fastening state without loosening the bolt even if vibration or shock is applied to the fastening portion of the bolt in the state that the fastening member and the fastening member is fastened through the bolt It is to provide a bolt fastening structure that can prevent the loosening of the bolt to be able to maintain the bolt as well as to separate the fastening member and the fastening member as necessary.

본 발명은 상기의 목적을 달성하기 위하여 볼트 머리부 상단으로 돌출되는 손잡이와 볼트 머리부의 하단으로 돌출되는 걸림돌기를 구비하는 걸림구를 볼트 머리부 상단 일측에 형성한 이동안내구멍에 상하방향으로 이동 가능하게 설치하는 동시에 스프링을 통해 탄성 지지하고, 볼트 수나사부의 나사산에 형성한 요입홈에 접착제가 충전된 다수의 캡슐이 일정 간격으로 배열 설치하며, 볼트의 수나사부가 관 통되는 체결부재 관통구멍의 외부 둘레에 상기 걸림구의 걸림돌기와 대응되는 환형 일방향 걸림홈을 형성하는 것을 특징으로 하며, 이하 그 구체적인 기술내용을 첨부도면에 의거하여 더욱 자세히 설명하면 다음과 같다.The present invention can be moved up and down in the movement guide hole formed in the upper end of the bolt head portion having a locking projection protruding toward the upper end of the bolt head and the handle protruding to the top of the bolt head in order to achieve the above object. At the same time, it is elastically supported by a spring, and a plurality of capsules filled with adhesive are arranged at regular intervals in the recessed groove formed in the thread of the bolt male thread part, and the outside of the fastening member through hole through which the male thread part of the bolt penetrates. It characterized in that to form an annular one-way locking groove corresponding to the locking projection of the locking hole on the periphery, hereinafter will be described in more detail based on the accompanying technical details.
