Description
본 발명은 볼트의 나선축에 체결되는 너트가 임의로 풀리는 것을 방지하기 위한 세이퍼락 너트에 관한 것으로, 특히 볼트의 나선축을 관통하는 상태로 체결되는 너트를 체결시켜 주거나 풀어주고자 할 때 나선축의 손상됨이 없는 상태에서 수월하게 체결 및 풀어질 수 있도록 함과 아울러, 나선축에 너트가 나선 체결된 상태에서는 체결력이 견고하여 외부의 진동이 발생되더라도 너트가 나선축에서 임의로 풀리는 현상이 없도록 한 세이퍼락 너트에 관한 것이다.The present invention relates to a safety lock nut for preventing the nut that is fastened to the helix of the bolt arbitrarily loosened, in particular when the nut is fastened or loosened when the nut is fastened to penetrate the helix of the bolt It is easy to fasten and loosen in the absence, and in the state that the nut is screwed to the spiral shaft, the tightening force is firm, so that the nut does not loosen arbitrarily from the spiral shaft even if external vibration occurs. It is about.
일반적으로 볼트와 너트는 전동차 및 자동차의 부속품 조립, 전자부품 조립, 가구의 조립 및 건설현장에서의 구조물 조립 등 다양한 분야에서 통상 2개 이상으로 분리되는 2개의 물체를 체결에 의해 결합시켜 주는 용도로서 넓게 사용되고 있는 것이다.In general, bolts and nuts are used to join two objects, which are usually separated by two or more, in various fields, such as electric vehicle and automobile accessory assembly, electronic component assembly, furniture assembly, and structure assembly in construction sites. It is widely used.
상기와 같이 볼트와 너트의 단순한 체결구조는 외부 충격이나 진동으로 체결력이 약화되는 단점이 있다. As described above, the simple fastening structure of the bolt and nut has a disadvantage in that the fastening force is weakened by external shock or vibration.
즉, 볼트의 나선축이 너트에 형성되어 있는 나선공에 체결되는 상태로만 되어 있어 사용도중 외부로부터 진동이나 충격이 가해질 경우 나선축에 체결되어 있는 너트가 임의로 풀리는 현상이 발생 됨에 따라 볼트와 너트에 의해 체결 고정된 2개의 구조물이 이격되는 단점이 있고, 심할 경우에는 볼트와 너트가 완전히 풀려 구조물이 떨어져 파손 및 붕괴가 이루어지게 되는 등의 안전사고가 발생되었던 것이다.In other words, the screw's screw shaft is in the state of being fastened to the screw thread formed in the nut. When vibration or shock is applied from the outside during use, the nut screwed on the screw shaft is loosened arbitrarily. There is a disadvantage in that the two structures are fastened and secured by space, and in severe cases, the bolts and nuts are completely loosened, so that the structure is broken and the collapse is made.
상기와 같이 볼트의 나선축에 나선체결 되어 있는 너트가 외부의 충격이나 진동이 발생되더라도 풀림이 발생되지 않도록 하여 안전사고의 위험이 없는 상태에서 사용할 수 있도록 하기 위하여 국내, 또는 국외에서 여러가지의 기술을 갖고 있는 풀림방지 너트를 개발하여 현재까지도 사용을 하고 있는 실정이다.As described above, in order to prevent loosening of the nut, which is screwed into the screw shaft of the bolt, even if an external shock or vibration occurs, various technologies can be used at home or abroad. Development of anti-loosening nut has been in use until now.
상기와 같은 여러가지의 풀림방지너트중 본원발명의 출원인이 개발하여 등록이 이루어진 특허등록 제902061호(파워클러치 너트)가 소개되어 현재 사용되고 있다.Patent No. 902061 (Power Clutch Nut) developed and registered by the applicant of the present invention among the various anti-loosening nuts as described above has been introduced and is currently used.
상기와 같은 종래의 파워클러치 너트는 단순히 너트의 내부에 형성되어 있는 요입홈부내에 요입되어 있는 코일스프링이 동일한 지름을 갖고 있는 상태에서 상,하 끝단부분이 외측을 향하도록 절곡시켜 상부의 절곡단부는 너트의 상단에 갖추어진 걸림홈부에 걸리는 상태로 고정되도록 하고, 하단의 절곡단부는 요입홈부의 하단측에서 외측으로 개방되도록 형성된 장공에 위치하도록 하여 볼트의 나선축을 너트에 체결시켜 주고자 할 경우 또는 체결되어 있는 볼트와 너트를 분해시켜 주고자 할 경우에는 너트에 씌워지도록 별도로 제작되어 있는 소켓을 너트에 씌워지도록 하면, 상기 소켓의 내부 일측에 갖추어져 있는 누름핀이 장공을 통해 외부로 노출되어 있는 절곡단부를 코일스프링이 풀어지는 방향으로 밀어주게 되어 나선축에 긴밀하게 감겨져 있던 코일스프링의 조임력이 상대적으로 약해짐에 따라 나선축과 체결되어 있는 너트를 풀어주게 되는 것이다.The above conventional power clutch nut is simply bent so that the upper and lower ends face outward in a state in which the coil springs inserted in the recess grooves formed inside the nut have the same diameter. If you want to fasten the helix shaft of the bolt to the nut to be fixed in the state that is caught in the engaging groove provided on the top of the nut, the bent end of the lower end is located in the long hole formed to open outward from the lower side of the recess groove Alternatively, if you want to disassemble the bolts and nuts that are fastened, if the socket is made to cover the nut to cover the nut, the push pin provided on one side of the socket is exposed to the outside through the long hole The bending end is pushed in the direction that the coil spring is unwound so it is closely wound on the spiral shaft Fastening force of the coil spring which will be relatively loose to give a spiral shaft and a nut which is fastened in accordance with the weakening.
그러나, 상기와 같은 종래의 너트는 나선축의 외주연을 긴밀하게 감싸주게 되는 코일스프링이 동일한 지름을 갖고 있어, 장공의 범위내에서 유동하게 되는 절곡단부의 이동범위 내에서만 코일스프링이 풀어질 수밖에 없어 코일스프링중 하단부의 절곡단부에 근접되고 있는 하부의 코일스프링은 나선축으로부터 느슨하게 풀어지는 현상이 발생 될 수 있으나, 상부에 위치하고 있는 코일스프링은 나선축으로부터 풀어지지 않게 됨에 따라 너트와 볼트를 풀어줄 때, 나선축으로부터 풀어지지 않은 코일스프링에 의해 나선축이 손상되는 현상이 있었던 것이다.However, the conventional nut as described above has the same diameter of the coil spring that tightly surrounds the outer circumference of the spiral shaft, so that the coil spring can only be released within the moving range of the bent end that flows within the long hole range. The lower coil spring near the bent end of the coil spring may loosen from the spiral shaft, but the upper coil spring is not released from the spiral shaft. In other words, the spiral shaft is damaged by the coil spring which is not released from the spiral shaft.
또한, 상기와 같은 코일스프링은 탄성이 상대적으로 높아 다른 공구 등을 사용해서는 장공내에 위치하고 있는 절곡단부를 밀어줄 수가 없어, 필히 너트에 씌워지면서 절곡단부를 이동시켜 줄 수 있는 전용소켓을 사용하여야만 하였으며, 만약 전용소켓이 없을 경우 너트를 풀어주지 못하게 되는 등의 단점이 있었던 것이다.In addition, the coil spring as described above has a relatively high elasticity, so other tools, etc., cannot push the bent end located in the long hole. Therefore, the socket must be used to move the bent end while being covered by the nut. If you do not have a dedicated socket, you will not be able to loosen the nut.
그리고, 너트가 나선축에 체결된 상태에서 진동이 발생되면 나선축의 외주연에 긴밀하게 감싸여져 있는 코일스프링의 조임력에 의해 너트가 임의로 풀리지 않게 되는데, 상기 코일스프링의 상단부가 외측 방향으로 절곡된 상태에서 상기 절곡된 절곡단부가 너트의 걸림홈부에 걸리는 상태로 고정되어 있어 진동이 상대적으로 심하게 발생 될 경우 절곡단부의 절곡된 부분이 부러지게 되는 등의 현상이 발생되었으며, 이러한 경우에는 나선축으로부터 너트를 풀어주지 못하게 되는 등의 제반결함이 있었던 것이다.In addition, when vibration occurs while the nut is fastened to the spiral shaft, the nut is not loosened arbitrarily by the tightening force of the coil spring that is tightly wrapped around the outer circumference of the spiral shaft, and the upper end of the coil spring is bent outward. In the bent end is fixed in a state that is caught in the locking groove of the nut, when the vibration is relatively severe, such a phenomenon that the bent portion of the bent end is broken, in this case the nut from the spiral shaft There are many defects such as not being able to release.
따라서, 본 발명은 볼트의 나선축에 너트가 나선 체결된 상태에서는 긴밀하게 체결 고정되어 사용도중 외부로부터 충격이나 진동이 발생하더라도 볼트와 너트가 임의로 풀리지 않도록 함과 아울러, 볼트에 형성된 나선축에 너트를 나선 체결시켜 주고자할 때, 또는 나선체결되어 있는 볼트와 너트를 풀어주고자 할 경우 코일스프링의 풀림이 고정된 상태가 유지될 수 있도록 하여 볼트와 너트의 조임 및 풀림을 수월하게 할 수 있도록 하는데 그 목적이 있는 것이다.Therefore, the present invention is tightly fixed and fixed in the state that the nut is screwed to the screw shaft of the bolt, so that the bolt and nut does not loosen arbitrarily even when shock or vibration occurs from the outside during use, and the nut on the screw shaft formed on the bolt To loosen the bolts and nuts that are screwed together or to loosen the bolts and nuts that are screwed together, the coil springs can be fixed so that the bolts and nuts can be easily tightened and loosened. The purpose is to.
또한, 본 발명은 볼트와 너트의 조임 및 풀림을 수행하고자 할 경우 코일스프링의 벌어지는 이동간격이 최소화되더라도 코일스프링의 벌어지는 간격이 최대화될 수 있도록 하여 코일스프링에 감겨져 있는 나선축의 손상됨이 없이 용이하게 조임 및 풀림이 수행될 수 있도록 하는데 그 목적이 있는 것이다.In addition, when the tightening and loosening of the bolt and nut is to be performed, the present invention allows the gap between the coil springs to be maximized even when the gap between the coil springs is minimized, thereby easily tightening without damaging the spiral shaft wound on the coil springs. And for the purpose of allowing the annealing to be performed.

상기와 같은 구성으로 하는 본 발명인 세이퍼락 너트(100)는 도 2a 에 도시된 바와 같이 코일스프링(400)이 너트(300)의 요입부(340)내에 요입되기 전에는 감김면(350)이 수직의 상태를 유지하고 있게된다.In the present invention, as shown in FIG. 2A, the safety lock nut 100 having the configuration as described above has the winding surface 350 of the coil spring 400 being vertically inserted into the recess 340 of the nut 300. It remains in state.
이러한 상태에서 도 2b 에 도시된 바와 같이 너트(300)의 요입부(340)내에 코일스프링(400)이 요입되도록 하되, 상기 코일스프링의 코일부(410) 하단 끝단부에 갖추어져 있는 절곡단부(440)는 안내장공(370)에 위치하도록 하고, 상단코일부(430)는 단턱면(360)에 얹혀지도록 한 상태에서 상기 원형너트부(330)의 상단에 갖추어져 있는 감김면(350) 부분을 내측으로 감겨지도록 하면, 상기 감김면이 단턱면(360)에 얹혀져 있는 코일스프링의 상단코일부(430)를 감싸는 상태로 하여 고정 결합시켜 주므로서, 너트의 성형이 완료되는 것이다.In this state, as shown in FIG. 2B, the coil spring 400 is inserted into the recess 340 of the nut 300, but the bent end 440 is provided at the bottom end of the coil part 410 of the coil spring. ) Is located in the guide hole 370, the upper coil portion 430 is placed on the stepped surface 360 in a state that is placed on the upper end of the circular nut portion 330 wound surface 350 is provided on the inside If it is to be wound, the winding surface is fixed to the upper coil portion 430 of the coil spring that is placed on the stepped surface 360 is fixedly coupled, the molding of the nut is completed.
이러한 상태에서 너트(300)에 볼트(200)를 체결시켜 주게 되는데, 우선 볼트(200)의 나선축(210)이 너트(300)에 체결되기 이전에는 도 3a 및 도 4a에 도시된 바와 같이 코일스프링(400)의 코일부(410) 자체의 조임력에 의해 상기 코일부(410)의 내경 일부분이 나선공(320)의 내경보다 다소 작은 지름을 갖고 있는 상태이며, 이러한 경우 상기 코일부(410)의 하단부 끝단에 갖추어진 절곡단부(440)는 안내장공(370)내에 위치한 상태에서 코일부(410)의 감겨지는 방향인 상기 안내장공의 좌측에 위치하고 있는 상태에 있는 것이다.In this state, the bolt 200 is fastened to the nut 300. First, before the spiral shaft 210 of the bolt 200 is fastened to the nut 300, as shown in FIGS. A portion of the inner diameter of the coil part 410 has a smaller diameter than the inner diameter of the spiral hole 320 by the tightening force of the coil part 410 itself of the spring 400, in this case the coil part 410 The bent end 440 provided at the lower end of the guide hole 370 is in a state in which it is located on the left side of the guide hole which is the winding direction of the coil unit 410.
상기와 같은 상태에서 상기 너트(300)의 하단부를 통해 나선공(320)에 볼트의 나선축(210)을 체결시켜 주게 되는데, 상기 나선공(320)을 관통하는 나선축(210)의 선단부분이 요입부(340)내에 위치하고 있는 코일스프링(400)의 코이루(410) 최하단부분이 절곡단부(440)에 접하게 되는 것이며, 이러한 상태에서 나선축의 지속적인 회전으로 인해 나선축의 외주연에 형성되어 있는 나선골의 최선단부분이 코일부(410)의 끝단부분과 맞추어지면서 도3b에 도시된 바와 같이 상기 코일부(410)가 나선축(210)의 외경에 맞추어 지름이 강제로 벌어지는 상태로 항여 나선축(210)의 외주연에 코일부(410)가 감겨지게 되는 것이다.In the state as described above to fasten the spiral shaft 210 of the bolt to the spiral hole 320 through the lower end of the nut 300, the tip portion of the spiral shaft 210 penetrating the spiral hole 320 The lower end of the coiled end 410 of the coil spring 400 located in the concave inlet 340 is in contact with the bent end 440, and is formed on the outer periphery of the spiral shaft due to the continuous rotation of the spiral shaft in this state. As the best end portion of the spiral bone is aligned with the end portion of the coil portion 410, as shown in FIG. 3B, the coil portion 410 is forced to open in a state where the diameter is forcibly opened in accordance with the outer diameter of the spiral shaft 210. The coil unit 410 is wound around the outer circumference of the shaft 210.
이때, 상기와 같이 나선축(210)의 외경에 의해 코일부(410)가 강제로 벌어지면서 나선축(210)에 감겨 감겨질 경우 코일부(410) 끝단에 갖추어져 있는 절곡단부(440)는 안내장공(370) 내에서 코일부의 벌어진 간격에 따라 중앙부분에 위치하게 되는 것이다.At this time, when the coil portion 410 is forcibly opened by the outer diameter of the spiral shaft 210 and wound around the spiral shaft 210, the bent end portion 440 provided at the end of the coil portion 410 is guided. In the long hole 370 is to be located in the center according to the gap between the coil portion.
상기와 같이 너트(300)의 나선공(320)에 나선축(210)이 체결되는 상태와 동시에 요입부(340)내에 위치하고 있는 코일스프링(400)이 나선축(210)의 외주연을 감싸주게 되면 코일스프링(400)의 자체 텐션력인 조임력에 의해 나선축(210)을 긴밀하게 잡아주고 있는 상태에 있으므로서, 사용도중 외부로부터의 진동 및 충격이 가해지거나, 인위적인 힘에 의해 볼트(200)와 너트(300)를 강제로 풀어주고자 하더라도, 볼트와 너트가 풀어지는 일이 없어 안전하게 사용을 할 수 있게 되는 것이다.At the same time as the spiral shaft 210 is fastened to the spiral hole 320 of the nut 300 as described above, the coil spring 400 located in the concave inlet 340 surrounds the outer circumference of the spiral shaft 210. When the spiral shaft 210 is closely held by the tightening force, which is the tension force of the coil spring 400, vibration and shock from the outside are applied during use, or the bolt 200 is caused by artificial force. Even if you want to forcibly loosen and nut 300, the bolt and nut will not be loosened will be able to use safely.
상기와 같은 상태로 하여 체결이 완료되어 있는 볼트와 너트를 풀어주고자 할 경우에는 일반적으로 널리 사용되고 있는 풀림수단(500)인 소켓(510)을 사용하여 풀어주면 되는 것이다.If you want to loosen the bolt and nut is completed in the above state is to use the socket 510, which is a loosening means 500 generally used.
즉, 도4b에 도시된 바와같이 소켓(510)의 씌움홈부(520)가 원형너트부(330)를 씌워주게 되는데, 이때 상기 육각의 모양을 갖고 있는 씌움홈부(520) 사이에 갖추어져 있는 요입홈부(530)중 어느 하나의 요입홈부(530)에 코일스프링(400)의 절각단부(440)가 위치하는 상태가 되도록 한다.That is, as shown in Figure 4b the covering groove 520 of the socket 510 covers the circular nut portion 330, wherein the recess groove provided between the covering groove 520 having the hexagonal shape The cutting edge 440 of the coil spring 400 is positioned in any one of the recessed grooves 530.
상기에서와 같이 요입홈부(530)에 절곡단부(430)가 위치하는 상태로 하여 원형너트부(330)에 소켓(510)의 씌움홈부(520)가 씌워지게 되면, 소켓의 육각모양을 갖고 있는 씌움홈부(520)와, 원형너트부(330)의 하단에 일체로 형성되어 있는 육각너트부(310)의 육각모양이 도4b에서 보는 바와 같이 엊갈린 상태를 갖고 있어 소켓(500)이 원형너트부(330)에만 씌워진 상태에 있게된다.As described above, when the bent end 430 is positioned in the recessed groove 530 and the covering nut 520 of the socket 510 is covered with the circular nut 330, the socket has a hexagonal shape. The hexagonal shape of the covering groove portion 520 and the hexagonal nut portion 310 integrally formed at the lower end of the circular nut portion 330 has a staggered state as shown in FIG. 4B, so that the socket 500 has a circular nut. Only the portion 330 is in the state covered.
이러한 상태에서 상기 볼트(200)는 고정되도록 한 상태에서 상기 소켓(500)을 코일스프링(400)이 풀리는 방향으로 회전시켜 주게 되면 이의 회전으로 인해 도3c와 도4c에 도시된 바와 같이 소켓(510)의 요입홈부(530)에 걸려있는 코일스프링(400)의 절곡단부(440)가 안내장공(370)의 우측 방향으로 강제 이동을 하게 되는 것이고, 상기와 같이 절곡단부의 강제 이동으로 인해 코일부(410)가 외측으로 벌어지면서 나선축(210)의 외주연으로부터 이격되는 상태가 되는 것이다.In this state, when the bolt 200 is rotated in the state in which the bolt 200 is fixed, the socket spring 510 is rotated in the direction in which the coil spring 400 is released. As a result, the socket 510 is illustrated in FIGS. 3C and 4C. Bent end portion 440 of the coil spring 400 hanging in the recess groove 530 of the) is to be forcibly moved in the right direction of the guide hole 370, as described above due to the forced movement of the bent end coil portion 410 is to be spaced apart from the outer periphery of the spiral shaft 210 while the outside.
상기와 같이 소켓(500)을 회전시켜 주게 되면 도3c에서 보는 바와 같이 육각의 모양을 갖고 있는 씌움홈부(520)와 육각너트부(310)가 일치하게 되는 것이고, 이러한 상태에서는 도4c에 도시된 바와 같이 씌움홈부(520)가 육각너트부(310)까지 씌워주게 되는 것이다.When the socket 500 is rotated as described above, as shown in FIG. 3C, the covering groove portion 520 having a hexagonal shape and the hexagon nut portion 310 coincide with each other. In this state, the socket 500 is shown in FIG. 4C. As described above, the covering groove 520 covers the hexagon nut portion 310.
상기에서와 같이 코일부(410)의 절곡단부(440)가 소켓(510)의 요입홈부(530)에 걸려있고, 소켓이 회전하여 코일부(410)가 나선축(210)의 외주연으로부터 벌어진 상태에서 육각너트부(310)에 씌움홈부(520)가 씌워지게 되면, 소켓(510)에 가해주던 힘을 해소시켜 주더라도 코일스프링(400)의 텐션력이 가해지더라도 소켓(510)이 임으로 회전되지 않아 코일부(410)가 나선축(210)으로부터 벌어진 상태에서 너트(300)와 볼트(200)의 나선축(210)을 수월하면서도 손상됨이 없는 상태에서 풀어줄 수 있게 되는 것이다.As described above, the bent end portion 440 of the coil portion 410 is caught in the recess 530 of the socket 510, and the coil portion 410 is rotated from the outer circumference of the spiral shaft 210 by rotating the socket. When the covering groove 520 is applied to the hexagon nut part 310 in the state, even if the tension applied to the coil spring 400 is applied, even if the force applied to the socket 510 is released, the socket 510 rotates randomly. If not, the coil unit 410 is to be released from the spiral shaft 210 of the nut 300 and the bolt 200 in the state unfolded from the spiral shaft 210 in an easy and undamaged state.
상기와 같이 소켓(510)을 사용하여 나선축(210)의 외주연에 자체의 텐션력에 의해 긴밀하게 감싸주고 있는 코일스프링(400)을 강제로 벌려줄 경우, 상기와 같이 강제로 벌려지게 되는 코일스프링은 최종적으로 어느 한쪽의 지점에 힘이 가해지게 되는데, 본 발명에서는 코일스프링(400)인 코일부(410)중 최상단에 위치하게 되는 상단코일부(430)를 코일부보다 다소 넓은 외경이 되도록 한 상태에서 원형너트부(330)의 단턱면(360)에 얹혀진 상태에서 감김면(360)에 의해 감겨져 견고하게 고정되도록 하고 있어 코일부(410)가 외압에 의해 강제로 벌어지는 힘이 코일스프링중 어느 한쪽에만 집중적으로 가해지는 것이 아니고, 코일부와 다소 큰 외경을 갖고 있는 상단코일부(430) 전체에 골고루 분산되면서 전달이 이루어져 강한 외압이 지속적으로 가해지더라도 코일스프링(400)이 절단되는 일이 없이 사용을 할 수 있게 되는 것이다. As described above, when the coil spring 400 is forcibly opened on the outer circumference of the spiral shaft 210 by the tension force of the spiral shaft 210, the socket 510 is forcibly opened as described above. The coil spring is finally applied to any one point, in the present invention, the outer coil portion 430 having an outer diameter somewhat wider than the coil portion in the upper coil portion 430 located at the top of the coil portion 410 that is the coil spring 400 The coil spring 410 is forced by the external pressure to be firmly fixed by being wound by the winding surface 360 while being mounted on the stepped surface 360 of the circular nut portion 330 in such a state that the coil spring is forced. It is not applied to only one of the intensive, evenly distributed evenly throughout the upper coil portion 430 having a somewhat larger outer diameter and the coil portion coils even if a strong external pressure is continuously applied The pring 400 will be able to use without being cut.
