너트 풀림방지기구{Nut Looseing Prevention Implement}Nut Looseing Prevention Implement

본 발명은 너트의 풀림을 방지하는 너트 풀림방지기구에 관한 것이다.The present invention relates to a nut loosening prevention mechanism for preventing loosening of a nut.

일반적으로, 부재와 부재를 고정시키기 위해 볼트와 너트가 사용된다.Generally, bolts and nuts are used to secure the member and the member.

도 1 내지 도 3은 종래의 볼트와 너트를 통한 부재와 부재의 고정을 설명하기 위한 도면으로서, 도 1 내지 도 3을 참조하여 볼트, 너트를 이용한 부재와 부재의 결합관계를 설명하면 다음과 같다.1 to 3 is a view for explaining the fixing of the member and the member through the conventional bolt and nut, with reference to Figures 1 to 3 when explaining the coupling relationship between the member and the member using the bolt, nut as follows. .

우선, 도 1를 참조하면, 상호 맞대어진 제1부재(P1)와 제2부재(P2)는 볼트(B)와 너트(N)의 상호결합에 의해 고정된다.First, referring to FIG. 1, the first member P1 and the second member P2 that are butted to each other are fixed by mutual coupling of the bolt B and the nut N.

이때, 상기 제1부재(P1) 및 제2부재(P2)는 관통홀(h1,h2)이 상하로 형성되며, 관통홀(h1,h2)에 볼트(B)가 삽입되고, 관통홀(h2) 외부로 노출된 볼트(B)에 너트(N)가 나사결합되어, 제1부재(P1)와 제2부재(P2)가 상호고정된다.In this case, the first member P1 and the second member P2 have through holes h1 and h2 formed up and down, and bolts B are inserted into the through holes h1 and h2, and through holes h2. The nut N is screwed to the bolt B exposed to the outside, and the first member P1 and the second member P2 are fixed to each other.

한편, 상기 볼트(B)와 너트(N)가 결합할 시, 볼트(B)에 너트(N)를 삽입하면, 도 2와 같이 볼트(B)의 나사산과 너트(N)의 나사산이 일정간격 이격된다. 이후, 공구 등을 이용해 너트(N)을 강하게 조이면, 너트(N)의 상방으로 강한 힘이 작용하면서 도 3과 같이 볼트(B)와 너트(N)의 나사산이 결합된다.On the other hand, when the bolt (B) and the nut (N) is coupled, when the nut (N) is inserted into the bolt (B), as shown in Figure 2 the screw thread of the bolt (B) and the screw thread of the nut (N) at regular intervals Spaced apart. Thereafter, when the nut N is firmly tightened using a tool or the like, a strong force acts upward of the nut N and the threads of the bolt B and the nut N are coupled as shown in FIG. 3.

이때, 상기 너트(N)는 상방으로 강한 힘이 작용함과 동시에, 볼트(B)의 나사산에 의해 하방으로 밀리려는 반작용력이 작용한다.At this time, a strong force acts upward on the nut N, and a reaction force to push downward by the thread of the bolt B acts.

따라서, 상기 제1부재(P1) 또는 제2부재(P2)에 외력이 작용할 시, 그 외력이 너트(N)가 저항할 수 있는 임계치를 넘어 작용하게 되면, 너트(N)가 볼트(B)로부터 풀리고, 이로 인해 너트(N)의 나사산과 볼트(B)의 나사산 면간 마찰이 줄어들어, 너트(N)와 볼트(B) 간의 결합력이 떨어진다. Therefore, when an external force acts on the first member P1 or the second member P2, if the external force acts above a threshold that the nut N can resist, the nut N is bolted to B. Loosened, which reduces the friction between the threads of the nut N and the threaded surfaces of the bolts B, thereby lowering the coupling force between the nuts N and the bolts B. FIG.

이러한 상황이 계속적으로 반복될 경우, 볼트(B)와 너트(N) 간의 결합력은 더욱 더 약해진다. 즉, 도 2와 같이 볼트(B)와 너트(N)의 나사결합이 헐거워져, 너트(N)가 제2부재(P2)에 가하는 가압력이 약해지므로, 제1부재(P2)와 제2부재(P2)의 고정성이 약해진다. If this situation is repeated repeatedly, the coupling force between the bolt B and the nut N becomes even weaker. That is, as shown in FIG. 2, since the screwing of the bolt B and the nut N becomes loose, the pressing force applied by the nut N to the second member P2 is weakened, so that the first member P2 and the second member are weakened. Fixability of (P2) is weakened.

이에 따라, 너트(N)의 풀림을 방지하는 수단이 요구되었다.Accordingly, a means for preventing loosening of the nut N has been required.

본 발명은 상기와 같은 과제를 해결하기 위한 것으로, 너트의 풀림을 방지하는 너트 풀림방지기구를 제공하는 것을 해결하고자 하는 과제로 한다. The present invention is to solve the above problems, to provide a nut loosening prevention mechanism for preventing loosening of the nut to be a problem to be solved.
