도 3은 볼트에 대해 회전 되는 과정에 있을 때의 상태를 나타낸 너트 어셈블리의 평면도이고, 도 4는 볼트에 대해 체결이 완료된 상태의 너트 어셈블리의 평면도이다.Figure 3 is a plan view of the nut assembly showing the state when in the process of being rotated with respect to the bolt, Figure 4 is a plan view of the nut assembly in the state that the fastening is completed for the bolt.
도 3 및 도 4를 참조하면, 너트 어셈블리(10)는 메인 너트(100)의 융기부(112)가 외벽 너트(200)의 수용부(210)에 위치된 상태로 볼트에 체결이 개시된다. 작업자가 공구 등을 이용하여 외벽 너트(200)를 회전 시키면, 메인 너트(100)는 외벽 너트(200)와 함께 회전 되면서 볼트에 대해 회전되면서 볼트에 체결된다.3 and 4, the nut assembly 10 is fastened to the bolt with the ridge 112 of the main nut 100 positioned at the receiving portion 210 of the outer wall nut 200. When the operator rotates the outer wall nut 200 using a tool or the like, the main nut 100 is rotated with the outer wall nut 200 and is fastened to the bolt while being rotated with respect to the bolt.
너트 어셈블리(10)가 볼트에 대해 어느 정도 회전되어 너트 어셈블리(10)의 상면이 너트 어셈블리(10)와 볼트 사이에 위치되는 구조물에 접하게 되면, 외벽 너트(200)에 볼트와 결합되는 방향으로 힘을 가하여도 메인 너트(100)는 회전되지 않는다. 이와 같은 상태에서 충분한 힘으로 외벽 너트(200)를 회전 시키면, 외벽 너트(200)가 메인 너트(100)에 대해 회전된다. 이 때, 융기부(112)는 외벽 너트(200)에서 수용부(210)가 형성되지 않은 면에 위치하게 된다. 외벽 너트(200)의 내면에서 수용부(210)가 형성되지 않은 면은 회전 중심에서의 거리가 수용부(210)에 비해 짧게 형성되므로, 융기부(112)에는 내측 방향으로 힘이 작용한다. 절개부(110)가 형성되어 있는 메인 너트(100)는 융기부(112)에 작용하는 힘으로 인해 둘레의 길이가 줄어들면서 볼트에 더욱 밀착된다. 따라서, 너트 어셈블리(10)는 볼트에 밀착되게 체결 가능하여, 진동 등으로 인한 힘이 인가 되어도 풀림이 방지될 수 있다.When the nut assembly 10 is rotated to the bolt to some extent and the upper surface of the nut assembly 10 is in contact with the structure located between the nut assembly 10 and the bolt, the force on the outer wall nut 200 in the direction of engagement with the bolt Even if the main nut 100 is not rotated. When the outer wall nut 200 is rotated with sufficient force in such a state, the outer wall nut 200 is rotated with respect to the main nut 100. At this time, the ridge 112 is located on the surface of the outer wall nut 200 in which the receiving portion 210 is not formed. The inner surface of the outer wall nut 200 is not formed in the receiving portion 210, since the distance from the center of rotation is formed shorter than the receiving portion 210, the force is applied to the raised portion 112 in the inward direction. The main nut 100 having the cutout 110 formed therein is more closely attached to the bolt while the length of the circumference decreases due to the force acting on the ridge 112. Therefore, the nut assembly 10 can be fastened to be in close contact with the bolt, so that the loosening can be prevented even when a force due to vibration or the like is applied.

The outer wall nut 201 is provided in a ring shape having a set width up and down. Since the receiving portion 220 formed on the inner surface of the outer wall nut 201 is the same as or similar to the outer wall nut 200 of FIG. 1, repeated descriptions thereof will be omitted.
메인 너트(101)의 외면과 외벽 너트(201)의 내면 가운데 하나에는 풀림홈(223)이 형상되고, 다른 하나에는 풀림돌기(124)가 형성된다. 도5 및 도 6에는 편의를 위해 메인 너트(101)의 외면에 풀림돌기(124)가 형성되고, 외벽 너트(201)의 내면에 풀림홈(223)이 형성된 경우를 도시하였다.A release groove 223 is formed in one of an outer surface of the main nut 101 and an inner surface of the outer wall nut 201, and a release protrusion 124 is formed in the other. 5 and 6 illustrate a case where the release protrusion 124 is formed on the outer surface of the main nut 101 and the release groove 223 is formed on the inner surface of the outer wall nut 201 for convenience.
풀림돌기(124)는 너트 어셈블리(11)가 볼트에 대해 체결이 완료될 때, 외벽 너트(201)가 메인 너트(101)에 회전되는 방향쪽이 턱이 지도록 형성된다. 또한 풀림돌기(124)는 상하 방향으로 설정 폭을 갖도록 형성될 수 있다. 풀림홈(223)은 풀림돌기(124)에 대응되는 형상으로 제공될 수 있다.The release protrusion 124 is formed such that the direction in which the outer wall nut 201 is rotated to the main nut 101 is jaw when the nut assembly 11 is fastened to the bolt.

If the outer wall nut 201 continues to rotate, the release groove 223 meets the release protrusion 124. Then, if the outer wall nut 201 continues to rotate, the main nut 101 is rotated with the outer wall nut 201 is released from the bolt.

As the nut assembly 14 is fastened to the bolt, the outer wall nut 204 rotates with respect to the main nut 104 such that the main nut 104 contracts, between the threads of the main nut 104 and the threads of the bolt. Slip may occur. In the process, the main nut 104 can be moved in the bolt direction. As the support 252 is provided to have an inclination, the main nut 104 may be in close contact with the bolt while being moved along the inclination of the support 252 during the contraction process. The outer wall nut 204 may be provided in the same or similar manner as the embodiment of FIG. 1, 5, or 10 to correspond to the main nut 104 except for the inclination formed in the support part 252.
