상기와 같이 구성된 볼트 및 너트 풀림방지구가 볼트 및 너트에 결합되는 상태 및 이에 따른 효과를 설명한다.The bolt and nut loosening prevention mechanism configured as described above is coupled to the bolt and nut and the effects thereof.

먼저, 볼트(10)와 너트(19)를 이용하여 결합물(28)과 결합상대물(30)을 결합고정한다. 볼트(10) 및 너트(19)에 의하여 결합물(28)과 결합상대물(30)이 결합고정되면, 볼트(10)의 헤드부(12)가 고정편(16)의 결합홈(14)에 위치되도록 볼트 및 너트 풀림방지구(40)를 결합물(28)과 결합상대물(30)에 위치시킨다. 이때, 고정편(16)의 결합홈(14) 내주면에 세레이션이 형성되어 있음으로 볼트(10)의 헤드부(12)가 결합홈(14)에 삽입되면, 볼트(10)의 헤드부(12) 각면이 세레이션에 밀착고정된 상태를 갖는다. 볼트(10)의 헤드부(12)가 고정편(16)의 결합홈(14)에 삽입된 상태에서 볼트 및 너트 풀림방지구(40)가 결합물(28)과 결합상대물(30)에 위치되면, 체결편(20),(24)의 내주면이 너트(19)의 외주면에 밀착되도록 제 2체결편(24)을 제 1체결편(20)에서 회동시킨다. 제 2체결편(24)의 일측이 제 1체결편(20)의 일측에 회동가능하게 결합고정되어 있음으로 제 2체결편(24)을 일측으로 회전시키면, 제 2체결편(24)이 제 1체결편(20)에서 회동되는 것이다. 제 2체결편(24)이 제 1체결편(20)에서 회동되면, 제 1체결편(20)의 내주면에 너트(19)의 외주면이 밀착되도록 위치시킨 상태에서 제 2체결편(24)을 최초의 위치로 회동시킨다. 이때, 너트(19)의 외주면에 체결편(20),(24)의 내주면이 밀착된 상태를 갖는다. 너트(19)의 외주면에 제 1체결편(20) 및 제 2체결편(24)의 내주면이 밀착되면, 제 2체결편(24)의 외주면 일측에 회전가능하게 결합고정된 걸고리(26)를 회전하여 제 1체결편(20)의 스톱퍼(22)에 결합고정한다. 이때, 스톱퍼(22)와 걸고리(26)의 결합으로 인하여 체결편(20),(24)의 내주면이 너트(19)의 외주면에 밀착고정된 상태를 갖는다.First, by using the bolt 10 and the nut 19, the combination 28 and the coupling partner 30 is fixed. When the coupling body 28 and the coupling partner 30 are fixed by the bolt 10 and the nut 19, the head portion 12 of the bolt 10 is coupled to the coupling groove 14 of the fixing piece 16. The bolt and nut loosening stop 40 is positioned in the combination 28 and the mating partner 30 so as to be located at. At this time, since the serration is formed on the inner circumferential surface of the coupling groove 14 of the fixing piece 16, when the head part 12 of the bolt 10 is inserted into the coupling groove 14, the head part of the bolt 10 ( 12) Each side has a state of being fixed close to the serration. In the state where the head portion 12 of the bolt 10 is inserted into the coupling groove 14 of the fixing piece 16, the bolt and nut loosening prevention portion 40 is connected to the coupling body 28 and the coupling partner 30. When positioned, the second fastening piece 24 is rotated at the first fastening piece 20 such that the inner circumferential surfaces of the fastening pieces 20 and 24 are in close contact with the outer circumferential surface of the nut 19. When one side of the second fastening piece 24 is rotatably coupled to one side of the first fastening piece 20, the second fastening piece 24 is rotated to one side. It is to be rotated in one fastening piece (20). When the second fastening piece 24 is rotated at the first fastening piece 20, the second fastening piece 24 is positioned in a state where the outer circumferential surface of the nut 19 is brought into close contact with the inner circumferential face of the first fastening piece 20. Rotate to the original position. At this time, the inner peripheral surface of the fastening pieces 20, 24 is in close contact with the outer peripheral surface of the nut 19. When the inner circumferential surfaces of the first fastening piece 20 and the second fastening piece 24 are in close contact with the outer circumferential surface of the nut 19, the hook 26 fixedly rotatably coupled to one side of the outer circumferential face of the second fastening piece 24 is provided. Rotating is fixed to the stopper 22 of the first fastening piece 20. At this time, due to the coupling of the stopper 22 and the hook 26, the inner circumferential surfaces of the fastening pieces 20 and 24 have a state of being closely fixed to the outer circumferential surface of the nut 19.

볼트(10)의 헤드부(12)가 고정편(16)의 결합홈(14)에 삽입된 상태에서 체결편(20),(24)이 너트(19)의 외주면에 밀착고정되어 있음으로 일정시간이 경과되거나 외부에서 일정 충격이 지속적으로 전달되어도 너트(19)가 볼트(10)에서 이탈되지 않는 것이다. 또한, 너트(19)가 볼트(10)에서 이탈되지 않음으로 결합물(28)과 결합상대물(30)의 분리로 인하여 발생되는 안전사고를 미연에 방지할 수 있는 효과를 갖는 것이다.In the state where the head portion 12 of the bolt 10 is inserted into the coupling groove 14 of the fixing piece 16, the fastening pieces 20 and 24 are fixed to the outer circumferential surface of the nut 19 to be fixed. Even if time passes or a constant shock is continuously transmitted from the outside, the nut 19 is not released from the bolt 10. In addition, since the nut 19 is not detached from the bolt 10, it is possible to prevent safety accidents caused by the separation of the coupling object 28 and the coupling partner 30 in advance.

도 3은 본 발명에 따른 다른 실시예를 보인 사시도이다. 도 3을 설명하면, 장방형의 형상을 갖는 지지플레이트(32)가 구비되고, 이 지지플레이트(32)의 상면에는 결합홈(34)을 갖는 고정부(36)가 길이방향으로 등간격배열된다. 결합홈(34)은 볼트(10)의 헤드부(12) 및 너트(19)와 동일한 형상을 갖도록 형성할 수 있음과 동시에 내주면에 세레이션이 형성된 원형으로 형성할 수도 있는 것이다. 상기와 같이 구성된 볼트 및 너트 풀림방지구(40)는 볼트(10)의 헤드부(12) 및 너트(19)가 삽입되는 고정부(36)가 상면에 복수개 구비되어 있음으로 복수개의 볼트(10) 및 너트(19)를 동시에 지지할 수 있는 것이다. 본 발명에 따른 볼트 및 너트 풀림방지구(40)는 위에 기술된 내용에 한정 하는 것이 아니라 결합되는 위치 및 장소에 따라 여러 형태로 제작되어질 수 있는 것이다.3 is a perspective view showing another embodiment according to the present invention. Referring to FIG. 3, a support plate 32 having a rectangular shape is provided, and fixing parts 36 having coupling grooves 34 are arranged at equal intervals in the longitudinal direction on an upper surface of the support plate 32. The coupling groove 34 may be formed to have the same shape as the head portion 12 and the nut 19 of the bolt 10 and may be formed in a circular shape having serrations formed on an inner circumferential surface thereof. The bolt and nut loosening prevention part 40 configured as described above has a plurality of bolts 10 because the head part 12 and the fixing part 36 into which the nut 19 is inserted are provided in plural on the upper surface. ) And the nut 19 can be supported at the same time. The bolt and nut loosening prevention part 40 according to the present invention is not limited to the above description but may be manufactured in various forms according to the position and place to be coupled.

상술한 바와 같이 본 발명에 따른 볼트 및 너트 풀림방지구는 볼트의 헤드부와 결합되는 고정편과 너트의 외주면에 밀착고정되는 체결편이 상단과 하단에 구비되어 있음으로 너트가 충격 등에 의하여 볼트에서 이탈되는 것을 방지할 수 있음은 물론 체결된 결합물과 결합상대물의 분리로 인하여 안전사고가 발생되는 것을 사전에 방지할 수 있는 효과를 갖는 것이다.As described above, the bolt and nut loosening prevention device according to the present invention is provided with a fastening piece coupled to the head of the bolt and a fastening piece fixed to the outer circumferential surface of the nut at the top and the bottom thereof so that the nut is separated from the bolt by impact. Of course, it can be prevented, of course, has the effect of preventing the occurrence of safety accidents due to the separation of the fastening and the coupling partner.
