Abstract

The present invention relates to an anti-loosening nut wherein an incline is formed in the lower surface of the anti-loosening nut, such that the inclined surface has the advantage of increasing the mutual coupling force and preventing loosening as the screw thread comes into intimate contact in one direction due to the force of establishing face-to-face contact during the process of assembly with various objects to be assembled therewith such as a bolt, and there is a greater surface area at the bottom surface of the inclined anti-loosening nut as compared with the bottom surface of a common anti-loosening nut that has no incline, such that the surface area of contact with the bolt is increased and consequently there are the advantages of stable installation and prevention of loosening of the anti-loosening nut, and also a cut-away slit is formed horizontally in the middle of the anti-loosening nut, and the cut-away slit is plastically deformed vertically such that the cut-away slit performs the role of a spring as the plastically deformed portion reverts to the state prior to deformation during the process of screw coupling with the bolt, and consequently the kinetic energy applied to the anti-loosening nut is converted to tension, and, by reducing the ensuing stress, it is possible to extend the life of the bolt and the anti-loosening nut. In an anti-loosening nut according to one embodiment of the present invention, a fastening hole having a screw thread on the inner circumferential surface thereof is provided passing through the centre thereof, and the lower surface is formed at an incline, while the cut-away slit is formed horizontally on the inside thereof.

Description

풀림방지 너트Loosen Nut
본 발명은 풀림방지 너트에 관한 것으로 더욱 상세하게는 풀림방지 너트의 하부면에 경사가 형성되어 있어 해당 경사면이 볼트와 같은 다양한 조립대상물과 상호 조립되는 과정에서 면접을 이루려는 힘에 의해 나사산이 일방향으로 밀착됨에 따라 상호 결합력이 증대 및 풀림 방지 효과가 있고, 경사가 없는 일반 풀림방지 너트의 하부면에 비해 경사진 풀림방지 너트의 하부면의 면적이 넓어 볼트와의 접촉면적이 증대됨에 따라 풀림방지 너트의 안정적 설치 및 풀림 방지 효과가 있으며, 풀림방지 너트 중앙에 수평방향으로 절개슬릿이 형성되되 절개슬릿이 수직방향으로 소성변형되어 있어 볼트와 나사결합되는 과정에서 소성변형된 부분이 변형되기 전의 상태로 복귀되면서 절개슬릿이 스프링의 역할을 수행함에 따라 풀림방지 너트에 가해지는 운동에너지를 장력으로 변환하여 그 스트레스를 저감해 줌으로써 볼트와 풀림방지 너트의 수명이 연장 되도록 할 수 있는 풀림방지 너트에 관한 것이다.The present invention relates to an anti-loosening nut, and more particularly, an inclined surface is formed on the lower surface of the anti-loosening nut, so that the thread is oriented in one direction by a force to be interviewed in the process in which the inclined surface is assembled with various assembly objects such as bolts. As the contact surface increases, the mutual bonding force is increased and the anti-loosening effect is increased, and the area of the lower surface of the inclined anti-loosening nut is wider than the bottom of the general anti-loosening nut without inclination, and thus the anti-loosening effect is increased. It has the effect of stable installation of the nut and prevention of loosening. The cutting slit is formed in the center of the anti-loosening nut in the horizontal direction, but the plastic slit is cut in the vertical direction. To the loosening nut as the incision slit acts as a spring The present invention relates to an anti-loosening nut that can extend the life of the bolt and anti-loosening nut by converting dynamic energy into tension to reduce the stress.
일반적으로 볼트와 풀림방지 너트는 기계장치 등의 부재를 정밀하면서도 용이하게 조립 및 고정할 수 있음으로 가장 많이 사용되는 기계요소의 하나이다. 그러나 볼트의 나사산과 풀림방지 너트의 나사산 간에는 상호 체결을 용이하게 하기 위해 약간의 유격이 반드시 존재하게 되는데, 이로 인하여 부재에서 발생하는 진동이나 충격에 의해 볼트와 풀림방지 너트는 순간적으로 헐거워지게 된다.In general, bolts and anti-loosening nuts are one of the most used mechanical elements because they can easily and easily assemble and fix members such as machinery. However, some clearance is necessarily present between the thread of the bolt and the thread of the anti-loosening nut to facilitate the mutual fastening. As a result, the bolt and the anti-loosening nut are loosened momentarily by vibration or shock generated from the member.
이에 따라 볼트와 풀림방지 너트의 체결상태가 양호하지 못하게 되어 기계장치 등의 조립 및 고정을 견고하게 하지 못하는 문제점이 있었는데, 이러한 문제점을 해결하기 위해 풀림방지 너트의 내측으로 스프링의 반발력에 의해 풀림방지 너트를 일측 방향으로 밀착시켜 볼트와 풀림방지 너트의 나사산 간의 유격을 제거하여 풀림을 방지하는 스프링와셔가 고안되었다. 그러나 이러한 스프링와셔는 그 탄성력이 저하되면 풀림방지 너트를 적정 힘으로 밀어주지 못하게 됨으로써 볼트와 풀림방지 너트의 나사산 간의 유격이 발생하게 되어 제 기능을 올바르게 발휘하지 못하는 문제점이 있었다.Accordingly, there is a problem in that the fastening state of the bolt and the loosening nut is not good, so that the assembly and fixing of the machine and the like cannot be secured. To solve this problem, the loosening prevention is prevented by the spring repulsion force inside the loosening nut. A spring washer was designed to prevent loosening by removing the play between the bolt and the thread of the anti-loosening nut by closely fitting the nut in one direction. However, such a spring washer has a problem that the clearance between the bolt and the thread of the anti-loosening nut is not able to push the anti-loosening nut with the proper force when the elastic force is lowered, so that there is a problem that it does not properly function.
이러한 문제점을 해결하기 위해 풀림방지 너트와 부재의 사이에 삽입되고, 부재에 형성된 테이퍼진 삽입홈에 삽입되게 외주면이 하향으로 테이퍼지게 형성되며, 일측이 소정길이로 절개된 스프링와셔 형태로 형성된 풀림방지용 삽입링이 고안됨에 따라, 테이퍼진 외주면과 스프링의 탄성력에 의해 스프링와셔의 작용과 동일하게 풀림방지 너트를 부재 방향으로 밀어줌으로써 풀림방지 너트와 볼트의 나사산 간의 유격을 제거하여 풀림을 방지할 수 있었다.In order to solve this problem is inserted between the anti-loosening nut and the member, the outer peripheral surface is tapered downward to be inserted into the tapered insertion groove formed in the member, for preventing loosening formed in the form of a spring washer cut in one side to a predetermined length. As the insertion ring is designed, the tapered outer circumferential surface and the elastic force of the spring can push the anti-loosening nut toward the member in the same direction as the action of the spring washer to remove the play between the anti-loosening nut and the thread of the bolt to prevent loosening. there was.
그러나 이러한 종래의 풀림방지용 삽입링은 상기한 바와 같이 부재에 삽입되도록 부재에 형성된 볼트공의 주연부에 삽입홈을 별도로 형성해야 하는 번거로움이 있었고, 이로 인하여 부재의 변형과 함께 삽입링이 기계장치 등의 작동에 따라 발생하는 진동이나 충격에 의해 유동함에 따라 부재의 손상을 주게 되는 문제점이 있었다. 뿐만 아니라 삽입홈을 형성하기 위해서는 부재의 두께가 적정 이상 되어야 함에 따라 두께가 얇은 부재의 경우에는 이를 적용할 수 없게 되는 문제점이 발생하게 되었다.However, such a conventional anti-loosening insertion ring has a hassle to separately form an insertion groove in the periphery of the bolt hole formed in the member to be inserted into the member as described above, and thus the insertion ring with the deformation of the member is a mechanical device, etc. There was a problem that damage the member as it flows by the vibration or shock generated by the operation of. In addition, in order to form the insertion grooves, the thickness of the member must be more than appropriate, so that a problem arises in that it cannot be applied to a thin member.
따라서 본 발명의 목적은 풀림방지 너트의 하부면에 경사가 형성되어 있어 해당 경사면이 볼트와 조립되는 과정에서 면접을 이루려는 힘에 의해 나사산이 일방향으로 밀착됨에 따라 상호 결합력이 증대 및 풀림 방지 효과가 있는 풀림방지 너트를 제공하는 것이다.Therefore, an object of the present invention is that the inclination is formed on the lower surface of the anti-loosening nut, so that the mutual coupling force is increased and the anti-loosening effect as the thread is in close contact with one direction by the force to make an interview in the process of assembling the inclined surface with the bolt.

전술한 풀림방지 너트(10)는 나사결합되는 다양한 볼트(20)의 규격에 대응되도록 다양하게 변경 실시 가능하며 그 재질은 금속으로 형성되고 하부면의 경사는 다양한 각도로 변경가능하되 1°내지 10°로 다양하게 변경될 수 있다. 또한 전술한 절개슬릿(11)은 풀림방지 너트(10)의 일측이 소성변형된 후 나사결합에 의해 복원가능하게 하는 역할을 하는 것이다. 이를 위해 전술한 절개슬릿(11)은 도 2에 도시되는 바와 같이 풀림방지 너트(10)의 일측 전체가 절개되고 체결공을 지나 타측 일부가 절개되도록 형성되는데 이와 같이 전체가 절개된 풀림방지 너트(10)의 일측의 상, 하부가 상호 연접되도록 소성변형이 이루어진다. 따라서 이와 같은 소정변형에 의해 체결공 내측의 나사산은 정상적인 나사산과 다르게 뒤틀려 있는바 볼트(20)와의 나사결합이 진행되는 과정에서 소성변형된 풀림방지 너트(10)의 형상이 원 상태로 복원된다.The above-mentioned anti-loosening nut 10 can be variously changed to correspond to the specifications of the various bolts 20 to be screwed together, and the material is made of metal, and the inclination of the lower surface can be changed at various angles, but 1 ° to 10 It can be changed to various degrees. In addition, the above-described cutting slit 11 serves to be restored by screwing after one side of the anti-loosening nut 10 is plastically deformed. To this end, the above-described incision slit 11 is formed such that the entirety of one side of the anti-loosening nut 10 is cut and a portion of the other side is cut through the fastening hole as shown in FIG. 2. Plastic deformation is performed so that the upper and lower portions of one side of 10) are connected to each other. Therefore, due to the predetermined deformation, the thread inside the fastening hole is twisted differently from the normal thread, so that the shape of the plastic deformation-unlocking nut 10 is restored to its original state in the process of screwing with the bolt 20.
이하에는 도 3 및 도 4b를 참조하여 본 발명의 일 실시예에 따른 풀림방지 너트(10)에 대해 상세하게 설명한다.Hereinafter, the anti-loosening nut 10 according to an embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4B.
먼저 도 3에 도시되는 바와 같이 풀림방지 너트(10)가 볼트(20)와 나사결합되면 소성변형되어 있던 풀림방지 너트(10)가 소성변형되기 전인 일반적인 풀림방지 너트(10)의 형상으로 복원이 이루어진다. 이때 절개슬릿(11)이 스프링의 역할을 수행함에 따라 풀림방지 너트(10)에 가해지는 운동에너지가 장력으로 변환되는데 풀림방지에 가해지는 운동에너지 즉, 스트레스를 저감해 줌으로써 풀림방지 너트(10) 및 볼트(20)의 수명이 연장될 수 있게 된다. 이때 풀림방지 너트(10)는 볼트(20)와 나사결합될 수도 있고 다양한 종류의 조립대상물과 조립될 수도 있으며 또한 풀림방지 너트(10)와 볼트(20) 사이에 다양한 종류의 조립대상물이 개재될 수도 있음은 물론이다.First, as shown in FIG. 3, when the anti-loosening nut 10 is screwed with the bolt 20, the anti-loosening nut 10, which was plastically deformed, is restored to the shape of the general anti-loosening nut 10 before plastic deformation. Is done. At this time, as the incision slit 11 serves as a spring, the kinetic energy applied to the anti-loosening nut 10 is converted into tension, and the kinetic energy applied to the anti-loosening, ie, stress is reduced, thereby preventing the anti-loosening nut 10. And the life of the bolt 20 can be extended. At this time, the anti-loosening nut 10 may be screwed with the bolt 20 or may be assembled with various kinds of assembly objects, and various kinds of assembly objects may be interposed between the anti-loosening nut 10 and the bolt 20. Of course you can.
그리고 풀림방지 너트(10)는 그 하부면이 경사지게 형성되어 있어, 도 4a에 도시되는 바와 같이 볼트(20)의 일면과 접촉될 경우 이격공간이 형성되게 된다. 이때 작업자가 풀림방지 너트(10)의 경사진 하부면이 볼트(20)의 일면과 완전히 면접 될 수 있도록 풀림방지 너트(10)에 회전력을 더 가해주면 도 4b에 도시되는 바와 같이 양측의 면이 면접 됨과 동시에 풀림방지 너트(10)의 나사산과 풀림방지 너트(10)가 체결된 볼트(20)의 나사산이 일방향으로 밀착됨에 따라 상호 결합력이 증대됨은 물론 풀림이 방지되는 효과를 갖게 된다.In addition, the anti-loosening nut 10 is formed to be inclined at its lower surface, so that a space is formed when contacted with one surface of the bolt 20 as shown in FIG. 4A. At this time, if the operator further applies a rotational force to the anti-loosening nut 10 so that the inclined lower surface of the anti-loosening nut 10 can be completely interviewed with one surface of the bolt 20, both sides of the anti-loosening nut 10 are shown in FIG. 4B. Simultaneously with the interview, as the thread of the anti-loosening nut 10 and the thread of the bolt 20 to which the anti-loosening nut 10 is fastened are adhered in one direction, the mutual coupling force is increased as well as the loosening is prevented.
뿐만 아니라 경사가 없는 일반 풀림방지 너트(10)의 하부면에 비해 경사진 풀림방지 너트(10)의 하부면의 면적이 넓어 볼트(20)와의 접촉면적이 증대됨에 따라 풀림방지 너트(10)의 안정적 설치 및 풀림 방지 효과를 갖게 된다.In addition, the area of the lower surface of the inclined loosening nut 10 is wider than the lower surface of the general loosening nut 10 without the inclination, so that the contact area with the bolt 20 is increased, It has a stable installation and anti-loosening effect.
