Abstract
The present invention relates to a lock nut assembly and a lock bolt assembly and, more particularly, to a lock nut assembly and a lock bolt assembly that employs one nut and allows the nut to be firmly coupled to a bolt without being loosened from the bolt.
Description
본 발명은 로크 너트 어셈블리 및 로크 볼트 어셈블리에 관한 것으로서, 더욱 상세하게는, 하나의 너트를 이용하여 너트가 볼트에서 풀리지 않도록 단단히 결합될 수 있도록 하는 로크 너트 어셈블리 및 로크 볼트 어셈블리에 관한 것이다.TECHNICAL FIELD The present invention relates to a lock nut assembly and a lock bolt assembly, and more particularly, to a lock nut assembly and a lock bolt assembly that allow a nut to be tightly coupled so as not to loosen from a bolt using one nut.
종래부터, 단단히 조인 너트가 느슨해져 버리는 것을 방지하는 풀림방지 잠금 너트가 제안되고 있다. 예를 들면, 일본 공개 실용신안 제1973-29257호에 기재의 풀림방지 잠금 너트는, 볼트에 나사 결합하는 상부너트와 하부너트로 구성되어 있고, 상기 상부 및 하부의 너트에는, 각각 서로 겹치도록 결합하는 테이퍼-상태의 볼록부와 오목부가 형성 되고 있다. 그리고, 상기 볼록부 또는 상기 오목부의 어느 쪽이든 한편의 중심이 조임볼트의 축심 선에 대해서 약간 편심되어 형성되고 있다. 이것에 의해, 상부 및 하부의 너트를 단단히 조이면, 볼록부와 오목부가 일부분으로 접해 나사 축을 기준으로 반경방향의 전단력을 발생시켜 너트가 볼트에 단단히 결합되므로, 너트의 풀림이 방지되는 효과를 발휘하게 되어 있다.Conventionally, the loosening lock nut which prevents a tightening nut from loosening is proposed. For example, the anti-locking lock nut described in Japanese Laid-Open Utility Model No. 1973-29257 is composed of an upper nut and a lower nut screwed to a bolt, and the upper and lower nuts are coupled to overlap each other. The tapered-state convex portions and concave portions are formed. The center of either the convex portion or the concave portion is formed to be slightly eccentric with respect to the axial line of the tightening bolt. Thus, when the upper and lower nuts are tightly tightened, the convex portion and the recessed portion are in contact with each other to generate radial shear force about the screw axis, and the nut is firmly coupled to the bolt, thereby preventing the nut from loosening. It is.
또, 일본 공개 특허 제2002-195236호에 기재된 풀림방지 잠금 너트는, 상부 너트의 측면의 하부 위치에 접촉부가 돌출되어 있어 이 접촉부에 단단히 조여 단부가 단단히 결합하기 때문에, 하부 너트의 공회전을 방지하는 것과 동시에, 접촉부의 위치에 의해 상부 너트의 회전 양을 파악할 수 있다.Moreover, since the contact part protrudes in the lower position of the side surface of an upper nut, and tightens it tightly to this contact part, the anti-locking lock nut of Unexamined-Japanese-Patent No. 2002-195236 prevents idle rotation of a lower nut. At the same time, the amount of rotation of the upper nut can be grasped by the position of the contact portion.
즉, 상기 기술된 선행기술문헌들은 볼트와 너트가 편심 결합되도록 유도하여 볼트와 너트의 결속이 더욱 단단해 지도록 하고 있다.In other words, the above-described prior art documents induce the bolt and nut to be eccentrically coupled so that the binding between the bolt and the nut is more firm.
이러한, 편심결합 너트는, 도난이 용이한 H-빔의 상호 결합, 송신탑의 트러스 구조 결합, 고속도로 등의 가드레일, 철로의 결합 등에 사용될 수 있으며, 도난 방지를 위해서는 필수적으로 볼트와 너트의 결합이 풀리지 않아야 한다.The eccentric coupling nut may be used for mutually easy H-beam coupling, truss structure coupling of transmission tower, guardrail of highways, railroad coupling, and the like. It should not be loosened.
하지만, 이러한 편심 결합에 의하더라도 편심결합력보다 큰 힘이 가해진다면 너트와 볼트가 풀릴 수 있고, 큰 힘이 아니더라도 반복적인 진동이나 떨림이 가해지는 경우에는 너트가 풀릴 수 있다는 단점이 있다.However, even with such an eccentric coupling, if a force greater than the eccentric coupling force is applied, the nut and the bolt may be loosened, and the nut may be loosened if repeated vibration or vibration is applied even if the force is not large.
또한, 이러한 편심결합 너트는 필수적으로 한 쌍의 너트가 필요하다는 점에서 단가절감을 저해할 수 있는 요인으로 작용하고 있다.In addition, such an eccentric coupling nut is required as a pair of nuts, which acts as a factor that can inhibit the unit cost reduction.

또한, 본 발명은 하나의 너트를 사용하여 상호 상대 풀림이 되지 않도록 하는 간단한 구조적 변경으로 단단한 결속이 가능한 로트 너트 및 로크 볼트를 제공하고자 한다.It is also an object of the present invention to provide a lot nut and lock bolt that can be tightly coupled with a simple structural change to prevent mutual loosening using a single nut.

도 1에서 보듯이, 상기 너트(210)의 내측면에는 상기 볼트(100)와의 결합방향으로 연장되고, 상기 볼트(100)와 결합하는 경우 내면이 원주방향으로 상기 볼트(100)의 외측면과의 간격이 커지도록 경사진 고정홈(211)이 적어도 하나 구비될 수 있다. 도면의 도시상으로는, 상기 고정홈(211)이 원주방향으로 소정 간격 이격하여 3개가 구비되는 것을 도시하였으나, 구비되는 고정홈(211)은 하나 이상일 수 있다.As shown in FIG. 1, an inner surface of the nut 210 extends in a coupling direction with the bolt 100, and when coupled with the bolt 100, an inner surface thereof is circumferentially formed with an outer surface of the bolt 100. At least one inclined fixing groove 211 may be provided to increase a distance therebetween. In the drawings, three fixing grooves 211 are provided in the circumferential direction at predetermined intervals, but the fixing grooves 211 may be provided.
여기서, 상기 고정홈(211)은 상기 볼트(100)와 결합하는 경우 내면이 원주방향으로 상기 볼트(100)의 외측면과의 간격이 커지도록 구비될 수 있으며, 상기 볼트(100)와 상기 너트(210)가 결합하는 경우에 상기 너트(210)가 회전하는 방향과 반대측 단부의 반경방향 간격이 가장 큰 잠금부재 안착부(211a)가 구비되도록 할 수 있다. 다시 말해, 상기 고정홈(211)은 상기 잠금부재 안착부(211a)에서 원주방향으로 상기 볼트(100)와 상기 너트(210)가 결합하는 경우에 상기 너트(210)가 회전하는 방향으로 상기 볼트(100)의 외측면과의 간격이 작아지도록 구비될 수 있다. 즉, 상기 고정홈(211)의 내면은 상기 너트(210)의 내측면, 즉, 나사선이 형성되는 원주방향에 대해 직선 내지는 둥근 형상으로 경사진 형상으로 구비될 수 있다.Here, when the fixing groove 211 is coupled to the bolt 100, an inner surface of the fixing groove 211 may be provided to increase the distance between the outer surface of the bolt 100 in the circumferential direction, the bolt 100 and the nut When the 210 is coupled, the lock member seating portion 211a having the largest radial spacing of the opposite side to the direction in which the nut 210 rotates may be provided. In other words, the fixing groove 211 is the bolt in the direction in which the nut 210 rotates when the bolt 100 and the nut 210 are coupled in the circumferential direction from the locking member seating portion 211a. It may be provided so that the interval with the outer surface of the 100 is small. That is, the inner surface of the fixing groove 211 may be provided in an inclined shape in a straight or round shape with respect to the inner surface of the nut 210, that is, the circumferential direction in which the thread is formed.
그리고, 상기 잠금부재 안착부(211a)에는 잠금부재(213)가 끼워질 수 있다. 상기 잠금부재(213)는 원통 형상으로 구비될 수 있다. 상기 잠금부재 안착부(211a)의 직경은 상기 잠금부재(213)의 직경보다 미소하게 크거나 거의 같은 사이즈일 수 있다.The locking member 213 may be fitted into the locking member seating portion 211a. The locking member 213 may be provided in a cylindrical shape. The diameter of the locking member seating portion 211a may be a size that is slightly larger than or substantially equal to the diameter of the locking member 213.
이에 따라, 상기 볼트(100)와 상기 너트(210)가 상호 결합되도록 상대회전하는 경우에는 상기 볼트(100)와 상기 잠금부재(213)가 접촉하더라도 상기 잠금부재(213)가 상기 잠금부재 안착부(211a) 내에서 자유롭게 회전하여 상기 볼트(100)와 상기 너트(210)가 잠금되도록 상대회전할 수 있다.Accordingly, when the bolt 100 and the nut 210 are rotated relative to each other, even if the bolt 100 and the locking member 213 contact, the locking member 213 is mounted on the locking member. The bolt 100 and the nut 210 may be rotated relative to each other so as to freely rotate within the 211a.
하지만, 상기 볼트(100)와 상기 너트(210)가 일단 잠금 방향으로 회전되고 난 후에 상기 너트(210)를 잠금 방향의 반대 방향으로 상대회전시키면 상기 볼트(100)와 상기 잠금부재(213)가 접촉하는 마찰에 의해 상기 잠금부재(213)가 상기 잠금부재 안착부(211a) 내에서 이탈하는 힘이 발생하고, 상기 잠금부재(213)는 잠금 방향으로 이동하게 된다. 이렇게 되면, 상기 고정홈(211)의 간격이 상기 너트(210)가 상기 볼트(100)에 잠길 때 회전하는 방향으로 상기 볼트(100)의 외측면과의 간격이 작아지도록 구비되므로, 상기 잠금부재(213)는 이동하지 못하고 고정홈(211)에 끼워진 상태로 상기 볼트(100)와 상기 너트(210) 사이에 단단히 걸림되게 된다. However, after the bolt 100 and the nut 210 are rotated in the locking direction once, the nut 210 is rotated in the opposite direction to the locking direction so that the bolt 100 and the locking member 213 are rotated. Due to the friction in contact, the locking member 213 is released from the locking member seating portion 211a is generated, the locking member 213 is moved in the locking direction. In this case, since the gap between the fixing groove 211 is provided so that the gap with the outer surface of the bolt 100 in the direction of rotation when the nut 210 is locked to the bolt 100, the locking member 213 does not move and is firmly caught between the bolt 100 and the nut 210 in a state of being fitted in the fixing groove 211.
이러한 원리에 의해 일단 상기 볼트(100)와 상기 너트(210)가 잠긴 후에는 단단히 락킹되어 풀수 없게 된다.By this principle, once the bolt 100 and the nut 210 are locked, they are locked firmly and cannot be loosened.
이하에서는 첨부된 도면을 참조하여 각 구성요소를 상세히 설명한다.Hereinafter, each component will be described in detail with reference to the accompanying drawings.

그리고, 상기 잠금부재 안착부(211a)에는 잠금부재(213)가 끼워질 수 있다. 상기 잠금부재(213)는 원통 형상으로 구비될 수 있다. 상기 잠금부재 안착부(211a)의 직경은 상기 잠금부재(213)의 직경보다 미소하게 크거나 거의 같은 사이즈일 수 있다.The locking member 213 may be fitted into the locking member seating portion 211a. The locking member 213 may be provided in a cylindrical shape. The diameter of the locking member seating portion 211a may be a size that is slightly larger than or substantially equal to the diameter of the locking member 213.
이에 따라, 상기 볼트(100)와 상기 너트(210)가 상호 결합되도록 상대회전하는 경우에는 상기 볼트(100)와 상기 잠금부재(213)가 접촉하더라도 상기 잠금부재(213)가 상기 잠금부재 안착부(211a) 내에서 자유롭게 회전하여 상기 볼트(100)와 상기 너트(210)가 잠금되도록 상대회전할 수 있다.Accordingly, when the bolt 100 and the nut 210 are rotated relative to each other, even if the bolt 100 and the locking member 213 contact, the locking member 213 is mounted on the locking member. The bolt 100 and the nut 210 may be rotated relative to each other so as to freely rotate within the 211a.

도 8의 (a)를 참조하면, 본 실시예에 따른 너트(210)의 실시예가 개시된다. 상기 너트(210)에는 잠금부재(213)를 고정하기 위해 구비되는 플랜지 와샤(214)가 고정될 수 있는 단차홈(212)이 구비될 수 있다. 상기 단차홈(212)은 상기 플랜지 와샤(214)의 본체면(214a)이 결합하는 제1단차홈(212a)과, 상기 제1단차홈(212a)에서 반경방향 내측방향으로 홈 형상으로 구비되고, 상기 플랜지 와샤(214)의 플랜지(214b)가 위치하는 제2단차홈(212b)을 포함할 수 있다. 이 경우, 상기 플랜지 와샤(214)의 본체면(214a)의 외경이 상기 제1단차홈(212a)을 형성하는 외경면에 압입되거나 슬라이드 결합될 수 있다.Referring to FIG. 8A, an embodiment of a nut 210 according to the present embodiment is disclosed. The nut 210 may be provided with a stepped groove 212 in which a flange washer 214 provided to fix the locking member 213 may be fixed. The stepped groove 212 is provided with a first step groove 212a to which the main body surface 214a of the flange washer 214 is coupled, and a groove shape in a radially inward direction from the first step groove 212a. The second step groove 212b may include a flange 214b of the flange washer 214. In this case, the outer diameter of the main body surface 214a of the flange washer 214 may be press-fitted or slide-bonded to the outer diameter surface forming the first stepped groove 212a.
그리고, 상기 플랜지 와샤(214)는 본체면(214a)과 상기 본체면(214a)의 내경에 상기 너트(210)의 내측면에 대향하도록 플랜지(214b)를 구비하고 상기 플랜지(214b)가 상기 너트(210)의 내측면에 끼움되면서 상기 고정돌기(213a)가 상기 플랜지(214b)에 걸림되어 상기 잠금부재(213)가 회전이 자유롭게 고정할 수 있다.The flange washer 214 includes a flange 214b at an inner diameter of the body surface 214a and the body surface 214a so as to face the inner surface of the nut 210, and the flange 214b is connected to the nut. The fixing protrusion 213a is caught by the flange 214b while being fitted to the inner side of the 210 so that the locking member 213 can be freely rotated.
도 8의 (b)를 참조하면, 다른 실시예에 따른 너트(210)의 실시예가 개시된다. 상기 너트(210)에는 잠금부재(213)를 고정하기 위해 구비되는 고정수단(214)이 삽입 내지는 안착될 수 이는 삽입홀(217)이 구비될 수 있다.Referring to FIG. 8B, an embodiment of a nut 210 according to another embodiment is disclosed. The nut 210 may be inserted or seated with a fixing means 214 provided to fix the locking member 213, which may be provided with an insertion hole 217.
특히, 도 8의 (b)는, 'ㄷ'자 형상의 고정수단(214)에 있어서, 양 단부의 절곡된 부분이 안착되는 수평 삽입홀(217a)을 구비하는 너트(210)가 개시된다. 본 실시예에 의하면 상기 고정수단(214)이 소정 위치에 정확하게 안착될 수 있을 뿐 아니라, 상기 너트(210)에서 상기 볼트(100)와 상기 너트(210)의 결합방향 면으로 상기 고정수단(214)이 돌출되지 않으므로 외형이 좋고 볼트와 너트의 결합을 더욱 단단하게 할 수 있다.In particular, FIG. 8B discloses a nut 210 having a horizontal insertion hole 217a in which bent portions of both ends are seated in the 'c' shaped fixing means 214. According to the present embodiment, not only the fixing means 214 can be accurately seated at a predetermined position, but also the fixing means 214 from the nut 210 to the coupling direction surface of the bolt 100 and the nut 210. Since it does not protrude, the appearance is good and the bolt and nut can be tightened more tightly.
다만, 도 8의 (b)는 'ㄷ'자 형상의 고정수단(214)에 있어서 중앙 부분은 여전히 볼트의 외측면에 돌출되게 되므로 문제될 수 있다. 이에, 도 8의 (c)는 'ㄷ'자 형상의 고정수단(214)에 있어서 중앙 부분까지 소정 위치에 정확하게 안착될 수 있도록 수직삽입홀(217b)을 더 구비하도록 할 수 있다.However, FIG. 8B may be a problem because the center portion of the 'c' shaped fixing means 214 still protrudes to the outer surface of the bolt. Thus, Figure 8 (c) may be further provided with a vertical insertion hole 217b in the 'c' shaped fixing means 214 to be accurately seated in a predetermined position up to the center portion.

도 11의 (a) 내지 (c)는 본 발명의 일 실시예에 따른 로크 너트 어셈블리가 볼트에 결합되는 일 예를 순서대로 도시한 참고도이다.11 (a) to 11 (c) are reference diagrams sequentially showing an example in which the lock nut assembly according to an embodiment of the present invention is coupled to a bolt.
먼저, 도 10의 (a)를 참고하면, 상호 결합할 제1 부재(1)와 제2 부재(2)를 맞댄 후, 일측에 볼트헤드(110)가 걸리도록 볼트(100)를 끼우고, 타측에 본 발명의 실시예에 다른 로크 너트 어셈블리(200)를 일반 너트결합 방식으로 끼움결합한다.First, referring to FIG. 10 (a), after the first member 1 and the second member 2 to be coupled to each other, the bolt 100 is fitted to the bolt head 110 on one side, Lock nut assembly 200 according to the embodiment of the present invention on the other side is fitted by a general nut coupling method.
다음으로, 도 10의 (b)를 참고하면, 상기 로크 너트 어셈블리(200)가 상기 볼트(100)에 결합되면서 상기 제1 부재(1)와 제2 부재(2)를 단단히 결합한 상태를 형성한다.Next, referring to FIG. 10B, the lock nut assembly 200 is coupled to the bolt 100 to form a state in which the first member 1 and the second member 2 are firmly coupled to each other. .
그 다음으로, 도 10의 (c)를 참고하면, 상기 로크 너트 어셈블리(200)에는 일단 너트(210)가 볼트(100)에 결합되면, 잠김시 회전방향과 반대방향으로 회전할 수 없으므로 상기 너트(210)는 상기 볼트(100)에 영구적으로 결합되게 된다.Next, referring to FIG. 10C, once the nut 210 is coupled to the bolt 100 in the lock nut assembly 200, the nut may not rotate in the opposite direction to the rotation direction when locked. 210 is to be permanently coupled to the bolt (100).
도 12은 본 발명의 일 실시예에 따른 로크 볼트 어셈블리의 기본 결합 형상을 도시한 사시도이다. 12 is a perspective view showing a basic coupling shape of the lock bolt assembly according to an embodiment of the present invention.
도 12을 참고하면, 일 실시예에 따른 로크 볼트 어셈블리(100)는, 너트(200)와 결합되도록 수나사산을 구비하고, 외측면에 상기 너트(200)와의 결합방향으로 연장되고 내면이 원주방향으로 상기 너트(100)와 결합하는 경우 상기 너트(100)의 내측면과의 간격이 커지도록 경사진 고정홈(111)이 적어도 하나 구비되는 볼트(110); 및 상기 너트(200)와 상기 볼트(110)의 결합방향으로 길게 구비되고, 상기 고정홈(111)에 끼워지는 원통 형상의 잠금부재(113);를 포함할 수 있다.Referring to FIG. 12, the lock bolt assembly 100 according to an embodiment includes a male screw thread to be coupled to the nut 200, and extends in a coupling direction with the nut 200 on an outer surface thereof, and an inner surface thereof in a circumferential direction. When the nut 100 is coupled to the bolt 110 is provided with at least one inclined fixing groove 111 so as to increase the interval with the inner surface of the nut 100; And a cylindrical locking member 113 provided in the coupling direction of the nut 200 and the bolt 110 and fitted into the fixing groove 111.
즉, 본 발명은 볼트(110)와 너트(200)가 일단 상호 회전결합한 후에는 결합 방향과 반대방향으로 상대회전이 되지 않도록 하여 결합된 상기 볼트(110)와 너트(200)가 풀리지 않도록 하는 로크 볼트 어셈블리에 관한 것이다.That is, in the present invention, the bolt 110 and the nut 200 are locked so that the bolt 110 and the nut 200 are not loosened after the rotation of the bolt 110 and the nut 200 so as not to be rotated relative to each other in the opposite direction. Relates to a bolt assembly.
도 12에서 보듯이, 상기 볼트(110)의 외측면에는 상기 너트(200)와의 결합방향으로 연장되고, 상기 너트(200)와 결합하는 경우 외면이 원주방향으로 상기 너트(200)의 외측면과의 간격이 커지도록 경사진 고정홈(111)이 적어도 하나 구비될 수 있다. 도면의 도시상으로는, 상기 고정홈(111)이 원주방향으로 소정 간격 이격하여 3개가 구비되는 것을 도시하였으나, 구비되는 고정홈(111)은 하나 이상일 수 있다.As shown in FIG. 12, the outer surface of the bolt 110 extends in a coupling direction with the nut 200, and when coupled with the nut 200, an outer surface of the bolt 110 is circumferentially coupled with the outer surface of the nut 200. At least one inclined fixing groove 111 may be provided to increase a distance therebetween. In the drawings, three fixing grooves 111 are spaced apart at predetermined intervals in the circumferential direction, but three fixing grooves 111 may be provided.
여기서, 상기 고정홈(111)은 상기 너트(200)와 결합하는 경우 원주방향으로 상기 너트(200)의 내측면과의 간격이 커지도록 구비될 수 있다. 더욱 상세하게는, 상기 너트(200)와 상기 볼트(110)가 잠금되도록 결합하는 경우에 상기 볼트(110)가 상대 회전하는 방향의 원주방향 단부 - 달리 표현하면, 너트(200)가 상대 회전하는 방향의 원주방향 반대방향의 단부 - 의 반경방향 간격이 가장 큰 잠금부재 안착부(111a)가 구비되도록 할 수 있다. Here, the fixing groove 111 may be provided to increase the interval with the inner surface of the nut 200 in the circumferential direction when it is coupled with the nut 200. More specifically, when the nut 200 and the bolt 110 are coupled to be locked, the circumferential end of the bolt 110 in the relative rotation direction-in other words, the nut 200 is relatively rotated. It is possible to provide the locking member seating portion (111a) with the largest radial spacing of the end-in the circumferentially opposite direction of the direction.
다시 말해, 상기 고정홈(111)은 상기 잠금부재 안착부(111a)에서 원주방향으로 상기 너트(200)와 상기 볼트(110)가 잠금결합하는 경우에 상기 볼트(110)가 상대 회전하는 방향으로 갈수록 상기 볼트(110)의 외측면과 상기 고정홈(111)의 바닥면과의 간격이 커지도록 구비될 수 있다. 즉, 상기 고정홈(111)의 내면은 상기 볼트(110)의 외측면, 즉, 나사선이 형성되는 원주방향에 대해 직선 내지는 둥근 형상으로 경사진 형상으로 구비될 수 있다.In other words, the fixing groove 111 is a direction in which the bolt 110 is relatively rotated when the nut 200 and the bolt 110 are locked in the circumferential direction from the locking member seating portion 111a. Increasingly, the distance between the outer surface of the bolt 110 and the bottom surface of the fixing groove 111 may be provided to increase. That is, the inner surface of the fixing groove 111 may be provided in an inclined shape in a straight or round shape with respect to the outer surface of the bolt 110, that is, the circumferential direction in which the thread is formed.
그리고, 상기 잠금부재 안착부(111a)에는 잠금부재(113)가 끼워질 수 있다. 상기 잠금부재(113)는 원통 형상으로 구비될 수 있다. 상기 잠금부재 안착부(111a)의 직경은 상기 잠금부재(113)의 직경보다 미소하게 크거나 거의 같은 사이즈일 수 있다.The locking member 113 may be fitted into the locking member seating portion 111a. The locking member 113 may be provided in a cylindrical shape. The diameter of the locking member seating portion 111a may be a size slightly larger than or substantially the same as the diameter of the locking member 113.
이에 따라, 상기 볼트(110)와 상기 너트(200)가 상호 결합되도록 상대회전하는 경우에는 상기 너트(200)와 상기 잠금부재(113)가 접촉하더라도 상기 잠금부재(113)가 상기 잠금부재 안착부(111a) 내에서 자유롭게 회전하여 상기 너트(200)와 상기 볼트(110)가 잠금되도록 상대회전할 수 있다.Accordingly, when the bolt 110 and the nut 200 rotate relative to each other, even if the nut 200 and the locking member 113 contact, the locking member 113 is the locking member seating portion. Rotation freely within 111a may allow the nut 200 and the bolt 110 to rotate relative to each other.
하지만, 상기 너트(200)와 상기 볼트(110)가 일단 잠금 방향으로 회전되고 난 후에 상기 볼트(110) 또는 너트(200)를 잠금 방향의 반대 방향으로 상대회전시키면 상기 너트(200)와 상기 잠금부재(113)가 접촉하는 마찰에 의해 상기 잠금부재(113)가 상기 잠금부재 안착부(111a) 내에서 이탈하는 힘이 발생하고, 상기 잠금부재(113)는 잠금 방향으로 이동하게 된다. 이 겨우, 상기 고정홈(111)의 간격이 상기 너트(200)가 상기 볼트(110)에 잠길 때 회전하는 방향으로 상기 볼트(110)의 외측면과의 간격이 작아지도록 구비되므로, 상기 잠금부재(113)는 이동하지 못하고 고정홈(111)에 끼워진 상태로 상기 볼트(110)와 상기 너트(200) 사이에 단단히 걸림되게 된다.However, after the nut 200 and the bolt 110 are rotated in the locking direction once, the bolt 110 or the nut 200 is rotated in the opposite direction to the locking direction. Due to the friction of the contact of the member 113, the locking member 113 is released from the locking member seating portion 111a is generated, the locking member 113 is moved in the locking direction. In this case, since the interval between the fixing groove 111 is provided so that the gap with the outer surface of the bolt 110 in the direction of rotation when the nut 200 is locked to the bolt 110, the locking member 113 does not move and is firmly caught between the bolt 110 and the nut 200 in a state of being fitted in the fixing groove 111.
이러한 원리에 의해 일단 상기 볼트(110)와 상기 너트(200)가 잠긴 후에는 단단히 락킹되어 풀수 없게 된다.By this principle, once the bolt 110 and the nut 200 are locked, they are firmly locked and cannot be loosened.
이하에서는 첨부된 도면을 참조하여 각 구성요소를 상세히 설명한다.Hereinafter, each component will be described in detail with reference to the accompanying drawings.
