본 고안은 풀림방지너트에 관한 것으로서, 보다 상세하게는 중공부의 둘레에 나선이 형성된 바디부의 상단에서 연장되는 연장부에 절개부가 형성되고, 상기 바디부의 하단에 형성된 리벳팅부에 와셔가 장착되는 풀림방지너트에 관한 것이다.The present invention relates to an anti-loosening nut, and more particularly, an incision is formed in an extension part extending from an upper end of a body part having a spiral around a hollow part, and an anti-loosening part in which a washer is mounted on a riveting part formed at a lower end of the body part. It is about nuts.

일반적으로, 볼트에 너트를 체결하여 물체를 고정하였을 때, 진동이나 충격에 의해 체결상태가 스스로 이완되는 경우가 많다. 이를 보완하기 위해, 너트와 물체 사이에 와셔를 삽입하거나, 너트와 볼트를 관통하는 핀을 체결하거나, 2개 이상의 너트를 볼트에 체결하였다.In general, when the object is fixed by fastening the nut to the bolt, the fastened state is often loosened by vibration or shock. To compensate for this, a washer was inserted between the nut and the object, a pin penetrating the nut and the bolt, or two or more nuts were fastened to the bolt.

그러나, 위와같은 종래의 수단은 작업자가 볼트에 너트를 체결할 때 불편하고 번거로움을 느끼는 단점이 있다. However, the conventional means as described above has the disadvantage that the operator feels inconvenient and hassle when fastening the nut to the bolt.

따라서, 본 고안의 목적은 중공부의 둘레에 나선이 형성된 바디부의 상단에서 연장되는 연장부에 절개부가 형성되고, 상기 바디부의 하단에 형성된 리벳팅부에 와셔가 장착되므로서, 볼트에 체결된 너트가 스스로 풀리는 것을 방지할 수 있으면서 볼트에 너트를 체결하여 고정하는 작업이 간편한 풀림방지너트를 제공하는 것이다.Therefore, an object of the present invention is to form an incision in the extension portion extending from the top of the body portion formed with a spiral around the hollow portion, the washer is mounted on the riveting portion formed on the bottom of the body portion, the nut fastened to the bolt itself It is possible to prevent loosening and to provide fastening nut that is easy to fix by fastening nut to bolt.

상기와 같은 목적을 달성하기 위한 본 고안의 바람직한 실시예를 도면을 참조하여 상세하게 설명하기로 한다.Preferred embodiments of the present invention for achieving the above object will be described in detail with reference to the drawings.

도 1 및 도 2를 참조하면, 본 고안에 따른 풀림방지너트(1)는 암나선부(3)가 형성된 바디부(5)의 상단에서 원통형의 연장부(7)가 연장되고, 상기 연장부(7)에 절개부(9)가 형성되고, 상기 바디부(5)의 하단에 형성된 리벳팅부(11)에 의해 바디 부(5)의 하단에 와셔(13)가 장착된다.1 and 2, the anti-loosening nut 1 according to the present invention is a cylindrical extension portion 7 is extended from the upper end of the body portion 5, the female spiral portion 3 is formed, the extension portion An incision 9 is formed in (7), and the washer 13 is mounted on the lower end of the body part 5 by the riveting part 11 formed at the lower end of the body part 5.

상기 바디부(5)에 형성된 암나선부(3)는 연장부(7)까지 연장되어 형성된다.The female spiral portion 3 formed on the body portion 5 extends to the extension portion 7.

도 2를 참조하면, 상기 와셔(13)는 리벳팅부(11)에 장착되는 내주면부(15a)가 외주면부(15b) 보다 높게 배치되도록 경사지게 형성된다.Referring to FIG. 2, the washer 13 is formed to be inclined such that the inner circumferential surface portion 15a mounted to the riveting portion 11 is disposed higher than the outer circumferential surface portion 15b.

도 3을 참조하면, 상기와 같이 구성된 본 고안에 따른 풀림방지너트(1)를 볼트(20)에 체결한 후, 풀림방지너트(1)를 조이면, 와셔(13)가 압착되면서 상기 와셔(15)의 반발력이 화살표(15) 방향으로 발생하므로서, 바디부(5)의 암나선부(3)와 볼트(20)의 수나선부(21)의 마찰력을 높임으로서, 암나선부(3)가 수나선부(21)에서 자동으로 풀리는 것을 방지할 뿐만 아니라, 연장부(7)의 상부면을 화살표(17) 방향으로 힘을 가하면, 절개부(9)가 압축되면서 연장부(7)가 변형되어, 연장부(7)의 암나선부와 볼트의 수나선부 사이의 체결공차가 변경되므로서, 볼트(20)에 체결된 풀림방지너트(1)가 볼트(20)에서 자동으로 풀려지지 않는다. 또한, 상기 풀림방지너트(1)는 절개부(9)가 형성된 연장부(7)가 육각형(또는 팔각형)의 바디부(5)와 일체로 형성되고, 와셔(13)가 바디부(5)에 합체되어 있어, 상기 풀림방지너트(1)를 볼트(20)에 체결하는 작업이 간편하게 이루어질 수 있다.Referring to FIG. 3, after the fastening prevention nut 1 according to the present invention configured as described above is fastened to the bolt 20, when the fastening prevention nut 1 is tightened, the washer 13 is pressed while the washer 15 is pressed. The repelling force of) increases in the direction of the arrow 15, thereby increasing the frictional force between the female threaded portion 3 of the body portion 5 and the male threaded portion 21 of the bolt 20. In addition to preventing the automatic release from the front portion 21, applying a force on the upper surface of the extension portion 7 in the direction of the arrow 17, the extension portion 7 is deformed while the incision 9 is compressed, Since the tightening tolerance between the female threaded portion of the extension portion 7 and the male threaded portion of the bolt is changed, the release preventing nut 1 fastened to the bolt 20 is not automatically released from the bolt 20. In addition, the loosening nut 1 has an extension part 7 having a cutout 9 formed integrally with the hexagonal (or octagonal) body part 5, and the washer 13 having the body part 5. It is incorporated in, the operation of fastening the loosening prevention nut 1 to the bolt 20 can be made easily.

위에서 설명한 바와같이, 본 고안에 따른 풀림방지너트는 볼트에 체결된 너트가 스스로 풀리는 것을 방지할 수 있으면서 볼트에 너트를 체결하여 고정하는 작업이 간편한 효과가 있다.As described above, the anti-loosening nut according to the present invention can prevent the nuts fastened to the bolts themselves, and there is an easy effect of fastening the nuts to the bolts.
