Description

볼트와 너트로 된 체결부재{conclusion member to be bolt and nut}Fastening member of bolt and nut {conclusion member to be bolt and nut}

본 발명은 체결부재에 관한 것으로, 더욱 상세하게는 체결부재를 구성하는 볼트와 너트가 서로 체결된 후 너트의 풀림과 손상을 보다 효과적으로 방지할 수 있도록 한 볼트와 너트로 된 체결부재에 관한 것이다.The present invention relates to a fastening member, and more particularly to a fastening member made of a bolt and a nut to more effectively prevent the loosening and damage of the nut after the bolt and nut constituting the fastening member is fastened to each other.

일반적으로 각종 기계장치 예를 든다면 항공기, 자동차 등과 같은 장치들에서 이들에 결합되는 부품들을 체결하기 위한 체결부재로 가장 널리 사용되는 것이 볼트와 너트이다. 이러한 볼트와 너트 중 그 체결상태를 보다 안정적으로 유지시키기 위하여 볼트에 결합된 너트의 풀림을 억제하기 위하여 캐슬너트(cattle nut)라는 것이 사용된다.In general, bolts and nuts are most widely used as fastening members for fastening components coupled thereto in devices such as aircraft and automobiles. In order to more stably maintain the fastening state among these bolts and nuts, a castle nut is used to suppress loosening of the nut coupled to the bolt.

이 캐슬너트는 다르게 플루티드 너트(fluted nut)라고도 하는데. 그 구성은 너트의 선단에 요철 형태로 방사상으로 다수개의 홈을 파고, 미리 볼트 나사부에 뚫어진 작은 구멍에 이 홈을 맞추어 고정핀을 꽂은 후 이 고정핀의 노출된 단부를 절곡시켜 너트를 볼트에 고정시키게 되어 있다.This castle nut is also called a fluted nut. The configuration is to dig a plurality of grooves radially at the tip of the nut in the form of unevenness, fit the groove into a small hole previously drilled into the bolt thread, insert the fixing pin, and then bend the exposed end of the fixing pin to fix the nut to the bolt. It is supposed to be.

그런데 이와 같은 종래의 캐슬너트의 경우 이 캐슬너트에 다수의 홈이 형성됨에 따라 그만큼 너트의 나사산 부분의 크기가 줄어들게 된다. 이에 따라 외부에서 인장력이 조금만 가해지더라도 너트의 결합상태를 유지시키기는 나사산의 결합부분이 작아 너트가 쉽게 풀리거나 파손되는 문제점이 발생한다.However, in the case of such a conventional castle nut, the size of the threaded portion of the nut is reduced by the number of grooves formed in the castle nut. Accordingly, even if only a slight tensile force is applied from the outside, the coupling portion of the screw thread is small to maintain the engaged state of the nut, so that the nut is easily loosened or broken.

본 발명은 전술한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 너트의 나사산 부분을 최대한 확보할 수 있도록 하여 외부에서 인장력이 가해지더라도 너트의 풀림을 최소화시키고, 또한 너트가 볼트와의 체결된 상태에서 풀리지 않고 보다 견고하게 그 체결상태를 유지할 수 있도록 구조를 개선한 볼트와 너트로 된 체결부재를 제공하기 위한 것이다.The present invention is to solve the above problems, the object of the present invention is to ensure the maximum threaded portion of the nut to minimize the loosening of the nut even if a tension force is applied from the outside, the nut is also fastened with the bolt It is to provide a fastening member made of bolts and nuts with improved structure to maintain the fastening state more firmly without loosening.

전술한 목적을 달성하기 위한 본 발명에 따른 체결부재는 머리부와 상기 머리부로부터 연장되며 외주에 나사부가 형성된 결합부와 상기 결합부에 일측에서 타측으로 관통하도록 형성된 슬롯을 구비한 볼트와; 상기 볼트의 결합부에 체결되며 외측면으로부터 내측으로 관통한 관통홀이 상기 슬롯과 연통하도록 형성된 너트와; 상기 너트의 관통홀을 통하여 상기 슬롯에 관통 결합되어 상기 너트의 고정 상태를 견고하게 유지시키는 고정핀을 구비한 것을 특징으로 한다.Fastening member according to the present invention for achieving the above object is a bolt having a head and a coupling portion extending from the head portion and a threaded portion formed on the outer circumference and a slot formed to penetrate from one side to the other side to the coupling portion; A nut coupled to the coupling part of the bolt and configured to communicate with the slot through-hole penetrating inward from an outer surface thereof; It is characterized in that it is provided with a fixing pin through the through-hole of the nut through the slot to securely maintain the fixed state of the nut.

그리고 바람직하게 상기 관통홀은 서로 대응하는 방향에 서로 마주하도록 다수개가 설치된 것을 특징으로 한다.And preferably the plurality of through-holes are installed so as to face each other in a direction corresponding to each other.

이하에서는 본 발명에 따른 하나의 바람직한 실시예를 도면을 참조하여 보다 상세히 설명하기로 한다Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the drawings.

본 발명에 따른 체결부재는 도 1과 도 2 그리고 도 3에 도시된 바와 같이 크게 볼트(100)와 너트(200) 그리고 고정핀(300)으로 되어 있다.Fastening member according to the present invention is largely composed of a bolt 100, a nut 200 and a fixing pin 300 as shown in Figs.

먼저 볼트(100)는 육각형 형태의 머리부(110)와 이 머리부(110)에서 연장되며 외주에 나사산이 형성된 체결부(120)로 되어 있다. 그리고 체결부(120)에는 상하 방향으로 길이가 긴 슬롯(130; slot)이 형성되어 있다.First, the bolt 100 has a hexagonal head portion 110 and a fastening portion 120 extending from the head portion 110 and having a thread formed on its outer circumference. In addition, the fastening part 120 is formed with a slot 130 having a long length in the vertical direction.

그리고 너트(200)는 육각형태의 외면을 형성하고, 그 내면에는 볼트(100)의 체결부(120)와 결합되는 나사산이 형성된 통상적인 형태로 되어 있는데, 더욱이 그 외측면에는 내측으로 관통한 다수개의 관통홀(210)이 형성되어 있다.The nut 200 has a hexagonal outer surface, and the inner surface of the nut 200 has a screw thread coupled to the fastening portion 120 of the bolt 100, and the outer surface of the nut 200 penetrates inwardly. Two through holes 210 are formed.

이 관통홀(210)은 각각의 육각 표면에 서로 상대하는 방향으로 각각 별도로 형성되어 있다. 다시 말해서 모두 여섯 개가 서로 대응하는 방향으로 각각 형성되어 있다는 것이다.The through holes 210 are formed separately on the respective hexagonal surfaces in the directions that correspond to each other. In other words, all six are formed in directions corresponding to each other.

그리고 고정핀(300)은 두 개의 다리(310)가 동일방향으로 위치하도록 절곡되어 있고, 이들의 절곡부분은 전술한 슬롯(130)과 관통홀(210) 보다 큰 직경을 가지는 머리부분을 형성하고 있다.And the fixing pin 300 is bent so that the two legs 310 are located in the same direction, the bent portion thereof forms a head having a larger diameter than the slot 130 and the through-hole 210 described above have.

이와 같이 구성된 본 발명에 따른 체결부재의 조립과 작용상태를 살펴보면, 결합을 위한 구조물에 볼트(100)를 관통 설치한 후 볼트(100)의 결합부(120)로 너트(200)를 삽입한 후 너트(200)를 별도의 공구를 사용하여 그 결합방향으로 회전시키면 너트(200)는 볼트(100)의 나사부(120)에 치합되면서 그 결합이 이루어진다.Looking at the assembly and the operating state of the fastening member according to the present invention configured as described above, after the bolt 100 is installed through the structure for coupling after inserting the nut 200 into the coupling portion 120 of the bolt 100 When the nut 200 is rotated in a coupling direction by using a separate tool, the nut 200 is engaged with the threaded portion 120 of the bolt 100, and the coupling is performed.

그리고 이러한 결합이 이루어진 후 너트(200)를 고정시킬 때에는 너트(200)의 관통홀(210)과 볼트(100)의 슬롯(130)의 위치를 맞춘 후 고정핀(300)을 너트(200)에 형성된 관통홀(210)을 통하여 끼우고, 계속해서 이 고정핀(300)의 다리부분이 상대하는 관통홀(210)을 통하여 관통 노출되도록 한다.When the nut 200 is fixed after the coupling is made, the fixing pin 300 is fixed to the nut 200 after aligning the position of the through hole 210 of the nut 200 and the slot 130 of the bolt 100. Inserted through the formed through hole 210, and the leg portion of the fixing pin 300 is continuously exposed through the through hole 210 to the counter.

그런 다음 이 고정핀(300)의 단부를 절곡시켜 견고히 고정시키면 너트(200)의 풀림 방지를 위한 설치가 완료된다.Then, by bending the end of the fixing pin 300 and firmly fixed, the installation for preventing the loosening of the nut 200 is completed.

즉, 본 발명에 따른 너트(200)는 종래에 사용된 캐슬너트에 비하여 그 나사산 형성부분이 최대한 확보된 상태이기 때문에 보다 견고한 결합상태의 유지가 가능하게 된다.That is, the nut 200 according to the present invention is more secure than the castle nut used in the prior art because the thread forming part is secured as much as possible to maintain a more firmly coupled state.

전술한 바와 같이 본 발명에 따른 체결부재는 너트의 풀림 방지가 아주 중요하게 보장되어야할 항공기 등과 같은 고정밀도 및 고 내구성을 가지는 장치들에 적용될 수 있을 것이다.As described above, the fastening member according to the present invention may be applied to devices having high precision and high durability, such as an aircraft, in which the prevention of loosening of the nut is very important.

한편, 이러한 본 발명의 볼트와 너트의 구조에서 볼트에 형성된 슬롯의 길이와 형태 그리고 너트에 형성된 관통홀의 형태와 숫자를 일부 변형하더라도 기본적으로 본 발명에서 청구하고 있는 구성을 포함한 것이라면 모두 본 발명의 기술적 범주에 포함된다고 보아야 한다.On the other hand, in the structure of the bolt and nut of the present invention even if some modifications to the length and shape of the slot formed in the bolt and the shape and number of the through-hole formed in the nut basically all the configuration including the claimed in the present invention It should be considered to be included in the category.

이상과 같은 본 발명에 따른 체결부재는 종래의 캐슬너트와 달리 너트의 나사산 형성부분을 최대한 확보한 상태에서 너트의 결합 고정을 위한 고정핀의 설치가 가능하도록 하여 외부 인장력이 가해지더라도 너트의 풀림을 최대한 억제할 수 있도록 함으로써 보다 향상된 체결력을 발휘할 수 있도록 하는 효과가 있다.The fastening member according to the present invention as described above, unlike the conventional castle nut to enable the installation of the fixing pin for the coupling fixing of the nut in the state to secure the thread-forming part of the nut to the maximum, even if the external tension is applied to the loosening of the nut By restraining as much as possible, there is an effect of exerting improved tightening force.
