Abstract
The present invention pertains to a self-locking nut which is prevented from loosening in a coupled state by more firmly coupling and fixing a spiral section and a female screw by forcibly screw-coupling the spiral section and female screw. Specifically, in order to prevent the permeation of damage factors (for example, water, rain, snow, wind or the like) into the nut via a portion, which is pressed and deformed, so as to increase durability life and prevent loosening due to the oxidation of the female screw and to improve stability in a general nut which is formed with a female screw (2) on the inner peripheral surface (1) thereof, the self-locking nut comprises a deformation groove (4) to be forcedly screw-coupled, wherein a groove is compressed in the outward direction from the inside surface of the inner peripheral surface (1) such that the groove is deformed and the width of the groove decreases, thereby reducing a distance between the female screw and the groove.
Description
본 발명은 볼트와 함께 기계요소들 중 하나로 여러 구조물에서 체결요소로 사용되며 볼트와 나사결합되는 너트에 관한 것으로서, 더욱 상세하게는 나사부와 암나사를 나사결합할 때 억지 나사결합시킴으로써 더욱 확고하게 결합 고정됨으로써, 체결된 상태가 풀리지 않도록 된 풀림방지 너트로, 특히 가압되어 변형되는 부위를 통해 너트의 내부로 손상인자(예컨데 물, 비, 눈, 바람 등)가 침투되는 것을 방지하여 내구수명을 증대함은 물론 암나사의 산화로 인하여 풀림되는 것을 방지하도록 되어 안정성을 향상시키도록 된 풀림방지 너트에 관한 것이다.The present invention relates to a nut which is used as a fastening element in various structures as one of mechanical elements together with a bolt, and which is screwed with a bolt, and more particularly, by firmly screwing when screwing a thread part and a female thread This prevents the fastening state from being loosened and prevents penetration of damage factors (e.g. water, rain, snow, wind, etc.) into the nut through the deformed portion, especially by pressing. Of course, the present invention relates to an anti-loosening nut configured to prevent loosening due to oxidation of the internal thread to improve stability.
일반적으로 자동차, 기계, 전기기구 등의 여러 구조물에는 볼트와 함께 볼트의 수나사에 나사결합되는 너트가 사용된다.In general, many structures, such as automobiles, machinery, electrical appliances, and the like are used nuts that are screwed to the male screw of the bolt together with the bolt.
이러한 너트의 조임방법에는 "토크 값 제어방식"과 "조임 각도 제어방식"의 두 가지가 있으며, 상기에서 토크 값 제어방식은 나사의 조임토크 결정(Tightening torque)하는 것으로 탄성영역을 넘지 않는 범위 내 소성영역 까지 조이는 방식이고, 조임 각도 제어방식(Angular tightening method)은 나사를 조일 때 일정 토크 값으로 1차조임을 하고 다시 일정한 각도만큼을 조이는 것이다.There are two methods of tightening the nut, namely, a "torque value control method" and a "tightening angle control method", and the torque value control method is a tightening torque of the screw, which does not exceed the elastic range. Tightening up to the plastic area, and the Angular tightening method is to tighten the screw first with a certain torque value and then tighten by a certain angle.
그러나 상기와 같은 일반적인 나사 체결방식은 진동 등의 외부요인에 의해 임의적으로 풀리는 문제점이 있어, 체결상태가 진동 등과 같은 외부요인에 의해 풀리지 않도록 하기 위한 구조들이 요구되고 있는 실정이다.However, the general screw fastening method as described above has a problem of being arbitrarily released by external factors such as vibration, so that a structure for preventing the fastening state from being released by external factors such as vibration is required.
이와 같은 풀림방지 구조를 가지는 너트에 대한 종래의 종류와 특성을 살펴보면 다음과 같다.Looking at the conventional type and characteristics of the nut having such an anti-loosening structure as follows.
첫째, 나사 변형 형:First, screw deformation type:
나사산을 일부 변형시켜 나사가 조여질 때 다시 원래대로 복원되면서 그 탄성으로 마찰력을 증대시켜 풀림 방지를 꾀하는 형태로서 다양한 형태로 찌그러뜨리고 있다.When the screw is partially deformed, the screw is restored to its original state when the screw is tightened, and its elasticity is increased to increase the frictional force to prevent loosening.
일 예로서 120도 각도로 3곳을 국부적으로 변형시켜 풀림을 방지하는 형태가 있고, 다른 예로서 작은 홈을 형성 한 후 안으로 변형시켜 놓아 조이면 벌어지지 않으려는 힘으로 풀림을 방지를 꾀하는 형태로서 120도 각도로 3곳을 넓게 눌러 변형시켜 풀림을 방지하게 된다.As an example, there is a form that prevents loosening by locally deforming three places at an angle of 120 degrees, and as another example, forms a small groove and deforms inward to prevent loosening with a force that does not open when tightened. Pressing three places at a wide angle to deform to prevent loosening.
둘째, 보조재 삽입 형:Second, the auxiliary insert type:
별도의 물질을 삽입하여 그 물질이 변형되면서 마찰 증대가 이루어져 풀림 방지를 꾀하는 형태이다.By inserting a separate material, the material is deformed to increase friction as it is deformed to prevent loosening.
일 예로서 나일론 인서트를 넣어 수나사가 나일론을 파고들어가 변형시킴으로써 풀림을 방지하는 예가 있고, 다른 예로서 판스프링을 넣어 수나사의 피치만큼 스프링이 변형되면서 나사산을 눌러 풀림을 방지하는 예가 있다.As an example, there is an example of preventing the loosening by inserting a nylon insert into the male screw to deform the nylon thread, and as another example, preventing the loosening by pressing the thread while the spring is deformed by the pitch of the male screw by inserting a leaf spring.
셋째, 고정 형:Third, fixed type:
분할 핀이나 혀붙이 와셔 등을 사용하여 너트가 회전되지 못하도록 물리적으로 고정하는 형태가 있고, 다른 예로서 홈 사이에 분할 핀을 꽂아 너트가 회전할 수 없게 고정함으로서 풀림을 방지하는 예가 있다.There is a form in which the nut is physically fixed to prevent the nut from being rotated by using a split pin or a tongue washer. As another example, a split pin is inserted between grooves to prevent the nut from rotating, thereby preventing loosening.
넷째, 더블 너트 체결 형태:Fourth, double nut fastening form:
볼트의 인장과 너트의 압축을 이용한 방법으로 먼저 너트 하나를 체결한 후 다음에 별도의 너트를 체결하는 예가 있다.There is an example of first tightening a nut and then a separate nut by using a bolt tension and a compression of a nut.
다섯째, 나사 풀림방지용 액체(록타이트)를 바르고 체결하는 예로서 체결완료 후에 록타이트가 굳으면서 풀림을 방지하는 것이다.Fifth, as an example of applying and tightening the screw anti-loosening liquid (Loctite) to prevent the loosening while Loctite is hardened after the completion of the tightening.
여섯째, 너트와 볼트를 체결 후에 너트를 용접 등으로 고정시키는 방법이 있다.Sixth, there is a method of fixing the nut by welding or the like after fastening the nut and the bolt.
일곱째, 너트 체결 후에 볼트의 나사산을 인위적으로 뭉개는 방법이 있다.Seventh, there is a method of artificially crushing the thread of the bolt after tightening the nut.
그리고 최근에 제안되어 사용되는 것으로, 너트의 측면에서 중심축선 방향으로 절결부를 형성하고 나사가 체결된 후에 절결부를 압착하여 암나사를 변형함으로써 암나사가 수나사를 압박하여 강하게 결속하도록 된 것이 있다.And it has been proposed and used recently, there is a thing that the female screw presses the male screw to strongly bind the female screw by deforming the female screw by forming the cutout in the direction of the center axis line on the side of the nut, and after the screw is fastened.
이와 같은 풀림방지 너트의 일 예로는 한국공개특허번호제10-2005-111219호(명칭: 이완 방지 너트와 그 제조방법)가 있다.An example of such an anti-loosening nut is Korean Laid-Open Patent No. 10-2005-111219 (name: anti-relaxation nut and its manufacturing method).
그러나, 상기와 같은 종래의 풀림방지 너트는 상기 절결부를 통해 외부와 내부가 연통되어 있어, 외부의 환경요인(예컨데, 비, 눈, 바람 등)이 내부로 침투하여 너트의 내부를 손상시키는 문제점이 있었다.However, the conventional loosening nut as described above is in communication with the outside and the inside through the cutout, the external environmental factors (for example, rain, snow, wind, etc.) to penetrate the inside to damage the inside of the nut There was this.
즉 너트의 내부를 부식시키는 등 내구수명을 저하시켜 안정성이 떨어지는 문제점이 있었다.That is, there is a problem that the stability is lowered by lowering the durability life, such as corroding the inside of the nut.
본 발명은 상기와 같은 종래의 문제점들을 해결하기 위하여 제안된 것으로서, 본 발명의 목적은 나사부와 암나사를 나사결합할 때 억지 나사결합시킴으로써 더욱 확고하게 결합 고정됨으로써, 체결된 상태가 풀리지 않도록 된 풀림방지 너트로, 특히 외부의 손상인자(예컨데 물, 비, 눈, 바람 등)가 너트의 내부로 침투되는 것을 방지하여 손상되지 않아 안정성을 현저히 향상시킨 풀림방지 너트를 제공하는 것에 있다.The present invention has been proposed to solve the conventional problems as described above, the object of the present invention is to more securely coupled by forcibly screwing when screwing the threaded portion and the female screw, thereby preventing the loosened state is not loosened A nut, in particular, provides an anti-loosening nut which prevents external damage factors (eg, water, rain, snow, wind, etc.) from penetrating into the nut and is not damaged to significantly improve stability.
상기와 같은 본 발명의 목적을 달성하기 위한 본 발명의 풀림방지 너트는 내주면에 암나사가 형성된 통상의 너트에 있어서;Anti-loosening nut of the present invention for achieving the object of the present invention as described above in the conventional nut formed with an internal thread on the inner peripheral surface;
상기 내주면에는 내측면에서 외측방향으로 형성된 홈을 압착하여 홈의 폭을 줄임으로서 변형시켜 암나사간의 거리를 줄여 나사결합할 때 억지 나사결합되도록 된 변형홈이 구비된 것을 특징으로 한다.The inner circumferential surface is deformed by compressing a groove formed in the outer side from the inner surface by reducing the width of the groove to reduce the distance between the female screw is characterized in that it is provided with a deformed groove that is forcibly screwed when screwing.
상기와 같은 본 발명의 풀림방지 너트는 나사부와 암나사를 나사결합할 때 억지 나사결합시킴으로써 더욱 확고하게 결합 고정됨으로써, 체결된 상태가 쉽게 풀리지 않도록 되어 있으며, 특히 너트의 외부에서 내부로 물 등과 같은 손상인자가 침투되지 않아 방지함으로써 장시간 사용하여도 너트의 내부가 산화되는 등의 손상을 입지 않아 안정성이 종래에 비하여 현저하게 향상된 효과를 가진다.The anti-loosening nut of the present invention as described above is more firmly coupled and fixed by forcibly screwing when screwing the threaded portion and the female screw, so that the fastened state is not easily loosened, especially damage such as water from the outside of the nut to the inside. By preventing the penetration of the factor, even if used for a long time does not damage the inside of the nut, such as oxidized, and has an effect of remarkably improved compared to the conventional.
도 1은 본 발명에 따른 일 실시예에 의한 풀림방지 너트를 보인 저면 사시 예시도.1 is an illustration of a bottom perspective view showing an anti-loosening nut according to an embodiment of the present invention.
도 2는 도 1에서 도시된 본 실시예의 풀림방지 너트의 제조과정을 보인 단면 예시도.Figure 2 is an exemplary cross-sectional view showing the manufacturing process of the anti-loosening nut of the present embodiment shown in FIG.
도 3은 도 1에서 도시된 본 실시예의 풀림방지 너트의 사용상태를 보인 사용사태 단면 예시도.Figure 3 is an exemplary cross-sectional view showing the use state of the anti-loosening nut of the present embodiment shown in FIG.
이하, 첨부된 도면을 참조하여 본 발명에 다른 바람직한 실시예에 의한 풀림방지 너트를 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the anti-loosening nut according to another preferred embodiment of the present invention.
도 1 내지 도 3은 본 발명에 따른 일 실시예에 의한 풀림방지 너트는 내주면(1)에 암나사(2)가 형성되어 있어, 나사부(3)(수나사를 포함하는)와 나사결합하여 여러 구조물을 체결하는 것에 사용된다.1 to 3 is a loosening nut according to an embodiment of the present invention has a female screw (2) is formed on the inner peripheral surface (1), by screwing the screw portion (including a male screw) several structures Used to fasten.
이와 같은 본 실시예의 풀림방지 너트에서 상기 암나사(2)가 형성된 내주면(1)에는 내측면에서 외측방향으로 파여져 형성된 홈을 압착하여 홈의 폭을 줄임으로서 변형시켜 암나사(2) 간의 거리를 줄여 나사 결합할 때 억지 나사결합되도록 된 변형홈이(4)이 구비된다.In the anti-loosening nut of the present embodiment, the inner circumferential surface 1 on which the female screw 2 is formed is squeezed from the inner side to the outer circumferential direction so as to reduce the width of the groove by reducing the width of the groove, thereby reducing the distance between the female screws 2. Deformation groove (4) is provided that is to be forcibly screwed when engaging.
이에 따라 암나사(2)가 수나사의 나사부(3)에 나사결합될 때 사이 간격이 줄어든 암나사(2)들과 억지 나사결합되어 더욱 확고하게 결합되게 함으로서 체결된 상태가 쉽게 풀리지 않는다.Accordingly, when the female screw 2 is screwed to the threaded portion 3 of the male screw, the tightened state is not easily loosened by allowing the female screw 2 to be tightly coupled with the female screw 2 having a reduced spacing therebetween.
즉 기존에는 암나사(2)와 나사부(3)가 나사 결합할 때 암나사(2) 간의 거리가 나사부(3)와 대응되어 단순 나사결합되기 때문에 나사결합이 풀리는 등의 문제점을 해결할 수 있다.That is, conventionally, when the female screw 2 and the threaded portion 3 are screwed together, the distance between the female screw 2 corresponds to the screwed portion 3 and is simply screwed, thereby solving problems such as loosening of the screw coupling.
특히 기존의 너트에 있어, 절결부를 통해 물 등의 손상인자가 외부에서 내부로 침투되어 내주면을 손상시키도록 된 것에 비하여, 본 실시예의 풀림방지 너트를 구성하는 변형홈(4)이 외부와 연통되어 있지 않아, 외부에서 내부로 물 등이 침투되지않아 손상을 입지 않는다.In particular, in the conventional nut, the deformed groove 4 constituting the anti-loosening nut of the present embodiment communicates with the outside, whereas a damage factor such as water penetrates from the outside to the inside through the cutout to damage the inner circumferential surface. It does not penetrate water from outside to inside, so it is not damaged.
따라서 장시간 사용하여도 너트의 내부가 산화되는 등의 손상을 입지 않아 안정성이 종래에 비하여 현저하게 향상된다.Therefore, even if it is used for a long time, the inside of the nut is not damaged, such as oxidation, and the stability is remarkably improved as compared with the related art.
그리고 본 실시예의 풀림방지 너트에서 상기한 변형홈(4)은 너트의 수직상 그 높이를 달리하면서 다수 개가 서로 마주보는 엇갈린 방향에 형성된다.In the anti-loosening nut of the present embodiment, the deformation grooves 4 are formed in a staggered direction in which a plurality of dogs face each other while varying their height vertically.
즉 변형홈(4)이 수직상 서로 엇갈린 형태로 되어, 변형홈(4)의 붕괴에 따른 암나사(2)와 나사부(4)의 강한 결속이 일측 방향에서만 이루어지는 것이 아닌 전체 면적에 고르게 이루어져 더욱 확고한 결합이 이루어진다.That is, the deformed grooves 4 are vertically staggered to each other, so that the strong binding of the female screw 2 and the threaded portion 4 due to the collapse of the deformed grooves 4 is not only made in one direction but evenly made in the entire area. The bond is made.
또한 본 실시예의 풀림방지 너트에서 상기한 변형홈(4)은 평면상 상기 내주면(1)의 중심축선을 넘는 위치에 이르고 있는 구성을 가진다.In addition, in the anti-loosening nut of the present embodiment, the above-described deformation groove 4 has a configuration that reaches a position exceeding the central axis of the inner circumferential surface 1 on a plane.
이에 따라 너트가 나사부(3)에 나사결합된 상태에서 측부를 가압하여 변형홈(4)을 압박하여 변형시킬 때, 용이하게 변형이 이루어짐은 물론 변형면적이 평면상 절반 이상 이루어져 확고히 강하게 결합된다.Accordingly, when the nut is deformed by pressing the side portion in the state in which the nut is screwed to the threaded portion 3 to press the deformation groove 4, the deformation is easily made as well as the deformation area is made more than half on the plane and firmly coupled.
그리고 본 실시예의 풀림방지 너트에서 상기한 변형홈(4)은 너트의 내주면(1)과 외주면간의 폭에 대하여 ½ 이상의 깊이로 형성된다.In the anti-loosening nut of the present embodiment, the deformation groove 4 is formed to a depth of ½ or more with respect to the width between the inner circumferential surface 1 and the outer circumferential surface of the nut.
따라서 너트가 나사부(3)에 나사결합된 상태에서 측부를 가압하여 변형홈(4)을 압박하여 형성시킬 때, 보다 용이하게 변형이 이루어진다.Therefore, when the nut is pressed by the side portion in a state in which the nut is screwed to the screw portion 3 to form the pressing groove 4, the deformation is more easily made.
상기와 같이 이루어진 본 실시예의 풀림방지 너트의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the loosening nut of the present embodiment made as described above in detail.
도 3 및 도 4는 본 실시예의 풀림방지 너트의 사용사태를 보인 도면으로, 본 실시예의 풀림방지 너트는 나사부(3)가 내주면(1)을 관통하면서 나사 결합하여 구조물을 체결하게 된다.3 and 4 is a view showing the use of the anti-loosening nut of the present embodiment, the anti-loosening nut of the present embodiment is screwed while the threaded portion 3 passes through the inner circumferential surface (1) to fasten the structure.
이때 암나사(2)가 수나사의 나사부(3)에 나사결합될 때 사이 간격이 줄어든 암나사(2)들과 억지 나사결합되어 더욱 확고하게 결합되게 함으로서 체결된 상태가 쉽게 풀리지 않는다.At this time, when the female screw 2 is screwed to the threaded portion 3 of the male screw, the tightened state is not easily loosened by allowing the female screw 2 to be more tightly coupled with the female screw 2 having a reduced spacing therebetween.
따라서 암나사(2)들과 나사부(3)가 더욱 확고하게 결합됨으로서 체결된 상태가 쉽게 풀리지 않는다.Therefore, the female screw 2 and the threaded portion 3 are more firmly coupled so that the fastened state is not easily released.
그리고 본 실시예의 풀림방지 너트는 외부에서 내부로 물 등과 같은 손상인자가 침투되지 않아 장시간 사용하여도 너트의 내부가 산화되는 등의 손상을 입지 않아 안정적이다.In addition, the anti-loosening nut of the present embodiment is stable because the damage factor such as water does not penetrate from the outside to the inside, so that the inside of the nut is not damaged even if used for a long time.
상술된 바와 같이 본 발명의 풀림방지 너트는 암나사가 변형되어 그 사이 간격이 줄어듬으로서 나사부와 억지 나사결합되어 더욱 확고하게 결합 고정됨은 물론, 외부의 물 등이 너트의 내부로 침투되는 것을 방지하도록 된 것을 기술적 구서의 특징으로 하여 장시간 사용하여도 안정성을 확보할 수 있도록 된 것을 특징으로 한다.As described above, the anti-loosening nut of the present invention has a female thread that is deformed so that the gap therebetween is reduced so that the screw and the screw are forcibly screwed together so as to be more firmly fixed and prevent external water from penetrating into the nut. It is a feature of the technical phrase that it is characterized in that it is possible to ensure stability even for long time use.
