Description
본 고안은 볼트와 결합하여 물체를 고정시키는데 사용되는 너트에 관한 것으로, 특히 너트의 내부에 코일형 나사를 삽입하여 분리되지 않도록 고정하고 볼트가체결되는 과정에서 강력한 체결력을 얻을 수 있도록 코일형 나사를 개선함으로써 진동이나 충격 등을 많이 받는 너트의 경우에 적합하게 사용되어 저절로 풀어지는 것을 완벽하게 방지하고, 체결작업도 편리하게 하려는 것이다.The present invention relates to a nut used in combination with a bolt to fix an object. In particular, the coil-type screw is inserted into the nut to fix it so that it is not detached, and a coil-type screw can be obtained to obtain a strong tightening force in the process of bolting. By improving it, it is suitable for the case of the nut which receives a lot of vibration or shock, so that it is completely prevented from loosening itself, and the fastening work is also convenient.
주지된 바와 같이 볼트와 너트를 체결하여 물체를 고정하였을 때 진동이나 충격이 가해지면 체결상태가 스스로 이완되는 경우가 많으므로 이를 방지하기 위한 수단이 강구되고 있는데, 예로는 스프링너트를 체결하는 것, 너트와 볼트를 관통하는 핀을 체결하는 것, 두개 이상의 너트를 동시에 체결하는 것 등이 있는데, 사용 용도에 따라서 적절한 것을 선택하여 사용하고 있다.As is well known, when the object is fixed by fastening the bolt and the nut, when the vibration or shock is applied, the fastening state often relaxes itself. Therefore, a means for preventing this is taken. For example, fastening a spring nut, There is a fastening of the pin through the nut and bolt, and the fastening of two or more nuts at the same time, the appropriate one is selected according to the intended use.
상기의 종래 수단들 중에서 두개 이상의 너트를 동시에 체결하는 경우에서의 문제점을 살펴보면, 하나의 너트를 먼저 강하게 체결한 다음 또 다시 다른 너트를 앞서 체결한 너트와 강하게 밀착되도록 체결하여야 하는 등 체결하는 과정이 불편하고 번거로운 것임은 물론이고, 강하게 조여두더라도 반복적인 진동이나 충격이 발생하면 너트간의 밀착력이 차츰 이완되므로 완벽한 이완방지 대책은 아니라 할 것이다.Looking at the problem in the case of fastening two or more nuts at the same time of the conventional means, the process of fastening such that the first fastening of one nut and then another fastening again to be in close contact with the previously fastened nut Not only is it uncomfortable and cumbersome, even if tightened tightly, if repeated vibration or shock occurs, the adhesion between the nuts gradually relaxes, so it will not be a perfect prevention measure.
한편, 볼트가 체결되는 모재가 무른 재질인 경우에 볼트의 체결과 분리를 반복하거나 볼트가 충격이나 진동을 받으면 모재의 나사구멍이 뭉그러지기 때문에 이를 방지하기 위하여 '스크링코일'이라고 불리는 나사형 코일을 삽입하는 경우가 있는데, 이는 상기한 바와 같이 무른 재질의 모재에 볼트를 체결하는 경우에 모재의 나사구멍을 보호하는데는 적합하지만, 볼트와 너트를 체결하는 구성에서 심한 진동과 충격으로부터 이완을 방지하는데는 적용할 수가 없었던 것이다.On the other hand, if the base material to which the bolt is fastened is a soft material, the screw hole of the base material is crushed when the bolt is repeatedly tightened and removed or when the bolt is impacted or vibrated. There is a case that is inserted, which is suitable for protecting the screw hole of the base material when the bolt is fastened to the base material of the soft material as described above, but in the configuration of tightening the bolt and nut to prevent relaxation from severe vibration and impact It could not be applied.
본 고안은 상기 문제점을 해결하기 위하여 안출한 것으로, 일반적인 강재의 너트에 나사형 코일을 삽입하여 구성하되, 나사형 코일이 너트의 구멍 내에 고정될 수 있는 구성과 볼트와 체결될 때 스프링 코일이 강력한 힘으로 볼트를 고정시키는 힘을 갖는 너트를 제공함으로써, 볼트와 결합하게 되면 볼트와 너트가 이완되는 것을 확실하게 방지할 수 있는 너트의 제공을 목적으로 하는 것이다.The present invention has been made in order to solve the above problems, it is configured by inserting a threaded coil into the nut of the general steel, the spring coil is strong when the screw coil is fastened to the bolt and the configuration that can be fixed in the hole of the nut It is an object of the present invention to provide a nut having a force that fixes the bolt by force, so that when combined with the bolt, the nut can be reliably prevented from loosening the bolt and the nut.

도 1은 본 고안의 전단면도, 도 2는 본 고안의 평면도, 도 3은 본 고안의 나사형 코일을 도시한 평면도, 도 4는 본 고안의 조립상태도이다.1 is a front sectional view of the present invention, Figure 2 is a plan view of the present invention, Figure 3 is a plan view showing a threaded coil of the present invention, Figure 4 is an assembled state diagram of the present invention.
본 고안의 너트(1)는 기본적으로 너트본체(10)와 그 내부에 삽입되는 나사형 코일(20)로 이루어진다.The nut 1 of the present invention basically consists of a nut main body 10 and a threaded coil 20 inserted therein.
먼저 너트본체(10)를 형성시에 결합할 볼트(30)의 치수와 나사형 코일(20)의 내외경 치수를 감안하여 내면나사부(10)를 먼저 형성하되, 볼트(30)의 치수와 동일한 내경을 가지도록 나사형 코일(20)을 구성하고, 나사형 코일(20)의 외경 치수와 동일하게 너트본체(10)의 내면나사부(10')를 가공하며, 그 후에 나사형 코일(20)을 너트본체(10)에 삽입하여 본 고안의 너트(1)를 완성하는 것이다.First, the inner thread portion 10 is first formed in consideration of the dimensions of the bolt 30 to be coupled at the time of forming the nut body 10 and the inner and outer diameters of the threaded coil 20, but the same as the dimensions of the bolt 30. The threaded coil 20 is configured to have an inner diameter, and the inner threaded portion 10 'of the nut body 10 is machined in the same manner as the outer diameter of the threaded coil 20, and thereafter, the threaded coil 20 Is inserted into the nut body 10 to complete the nut 1 of the present invention.
본 고안의 너트(1)에서는 너트본체(10)에 삽입되는 나사형 코일(20)의 높이가 너트본체(10)의 높이보다 좀더 작게 구성하여 돌출되지 않도록 삽입한 후, 너트본체(10)의 내면나사부(10')에서 나사형 코일(20)의 끝단이 위치하는 부분에 각각 압입부(11)(12)를 형성하여 나사형 코일(20)이 삽입된 후에는 회전하지 못하도록 하여 이탈을 방지하였다.In the nut 1 of the present invention, the height of the threaded coil 20 inserted into the nut main body 10 is made smaller than the height of the nut main body 10 so as not to protrude, and then the nut main body 10 of the nut main body 10 Indentation parts 11 and 12 are formed in the inner threaded part 10 'at the end of the threaded coil 20 to prevent the screw coil 20 from rotating after the threaded coil 20 is inserted. It was.
상기 압입부(11)(12)는 너트본체(10)의 내면나사부(10')를 강하게 눌러 나사부의 형태가 변형되면서 나사로서의 역할을 할 수 없도록 하는 것이다.The press-fitting parts 11 and 12 strongly press the inner screw portion 10 ′ of the nut body 10 so that the shape of the screw portion is deformed and thus cannot serve as a screw.
또한 나사형 코일(20)은 중간 임의의 부위가 다른 부위보다 내부 쪽으로 약간 돌출(도 1에서 'L')된 수개의 압박부(21)를 구성하였다.In addition, the threaded coil 20 constituted several pressing portions 21 in which any portion of the middle portion projected slightly toward the inside ('L' in FIG. 1) than the other portions.
이러한 압박부(21)는 원형을 이루는 나사형 코일(20)을 균일한 각도로 분할한 후 일정한 각도로 형성하는 것이 바람직하고 용도나 기타의 목적에 따라서 구성하는 부위나 각도, 크기 등을 가감할 수 있으나, 통상 전체 중에서 중간 위치에 두바퀴 권회되는 과정에서 6회 정도 돌출되는 것이 바람직할 것으로 판단된다.The pressing portion 21 is preferably formed at a constant angle after dividing the circular threaded coil 20 at a uniform angle, depending on the purpose or other purposes it is possible to add or subtract the portion, angle, size, etc. In general, it is determined that it is preferable to protrude about six times in the process of being wound twice in the middle of the whole.
도면중 미 설명된 부호 30은 볼트이다.Reference numeral 30 in the figure is a bolt.
이하는 상기와 같은 구성으로 된 본 고안의 너트(1)에 대한 작용을 상세히 살펴본다.Hereinafter, look at the action on the nut (1) of the present invention having the configuration as described above in detail.
먼저 결합할 물체에 볼트(30)를 관통시킨 다음, 본 고안의 너트(1)를 결합하는데, 실질적으로는 너트본체(10)의 내부에 결합된 나사형 코일(20)에 볼트(30)가 체결되는 것이다.First, the bolt 30 is penetrated to the object to be coupled, and then the nut 1 of the present invention is coupled. The bolt 30 is substantially attached to the threaded coil 20 coupled to the inside of the nut body 10. It is fastened.
나사형 코일(20)에 볼트(30)를 체결할 때 나사형 코일(20)에도 볼트(30) 또는 너트(1)와 같이 회전하려는 힘이 작용하게 되는데, 본 고안에서는 나사형 코일(20)의 양쪽 선단부가 압입부(11)(12)에 의해 걸려 있는 상태이므로 나사형 코일(20)은 너트본체(10)와 일체화되는 것이고, 따라서 너트(1)가 볼트(30)에 체결될 수 있는 것이다.When the bolt 30 is fastened to the threaded coil 20, a force to rotate like the bolt 30 or the nut 1 also acts on the threaded coil 20, in the present invention, the threaded coil 20. Since both end portions of the screw coil 20 are hung by the press-fitting portions 11 and 12, the nut coil 10 is integrated with the nut body 10, and thus the nut 1 may be fastened to the bolt 30. will be.
또한 볼트(30)가 압박부(21)를 통과하게 되면 강력한 체결력이 발생하는데, 나사형 코일(20)에서 다른 부분 보다 돌출된 압박부(21)를 볼트(30)가 통과하게 되면, 볼트(30)가 돌출된 압박부(21)와 체결이 이루어지기 때문에 볼트(30)의 나사산이 압박부(21)와 강하게 물리게 되면서 체결이 이루어지는 것이며, 이러한 강한 체결과 아울러 압박부(21)가 구성된 부분의 나사형코일(20)이 바깥쪽으로 밀려나려는 힘이 발생하고 이러한 압박부(21)의 밀려나는 작용이 압입부(11)(12)에 의해 제한을 받으므로 나머지 정상적인 다른 부분의 나사산이 중앙의 볼트(30)를 향해 몰리는 현상이 발생하는 것이다.In addition, when the bolt 30 passes through the pressing portion 21, a strong fastening force is generated. When the bolt 30 passes through the pressing portion 21 protruding from other portions of the threaded coil 20, the bolt ( 30 is protruding from the pressing portion 21 is protruding, so that the screw thread of the bolt 30 is strongly snapped with the pressing portion 21, and the fastening is performed. Of the threaded coil 20 is pushed outward and the pushing action of the pressing portion 21 is limited by the press-in portions 11 and 12, so that the other threads of the other normal portion The phenomenon of being driven toward the bolt 30 occurs.
따라서 나사형 코일(20) 전체가 볼트(30)를 압박하면서 체결되는 결과로 이어지므로 매우 강력한 체결력을 얻을 수 있는 것이다.Therefore, the entire screw-type coil 20 leads to the result of being fastened while pressing the bolt 30 will be able to obtain a very strong fastening force.
이상 설명한 바와 같은 본 고안은 너트(1)의 내부 나사부에 나사형 코일(20)을 삽입하되 나사형 코일(20)이 삽입되는 전 후에 압입부(11)(12)를 형성하여 나사형 코일(20)이 분리되지 못하게 잡아주고, 동시에 나사형 코일(20)의 중간에 압박부(21)를 구성함으로써 나사형 코일(20) 전체가 볼트(30)를 강하에 조여주면서 체결이 이루어지므로 매우 강력한 체결이 이루어지는 것이며, 따라서 진동과 충격이 많은 장소에 결합되는 볼트의 경우에 본 고안의 너트를 적용하게 되면, 체결작업이 복잡하지 않으면서도 풀림을 걱정할 필요없이 체결력을 유지할 수 있게 되는 등 기본적인 기계요소인 볼트 및 너트의 작업성 향상과 및 이완방지에 매우 유용한 고안이라 할 수 있다.As described above, the present invention inserts the threaded coil 20 into the internal threaded portion of the nut 1, but forms the press-fitting portions 11 and 12 before and after the threaded coil 20 is inserted into the threaded coil ( 20) is held apart from each other, and at the same time by forming the pressing portion 21 in the middle of the threaded coil 20, the entire threaded coil 20 is tightened while tightening the bolt 30 in a strong, so very strong When the nut of the present invention is applied to a bolt that is coupled to a place having a lot of vibration and impact, it is possible to maintain a fastening force without having to worry about loosening without complicated screwing work. It can be said that the design is very useful for improving workability and preventing relaxation of the in bolt and nut.
