Description

너트 풀림 방지용 체결볼트{Joint bolt to prevent nut unfasten}Joint bolt to prevent nut unfasten}

본 발명은 너트 풀림 방지용 체결볼트에 관한 것으로, 더욱 상세하게는 소정의 구조물을 결합시키도록 체결되며 그 체결된 상태에서 너트의 풀림이 방지되도록 한 너트 풀림 방지용 체결볼트에 관한 것이다.The present invention relates to a fastening bolt for preventing nut loosening, and more particularly, to a fastening bolt for preventing loosening of nuts to be fastened to couple a predetermined structure and to prevent loosening of nuts in the fastened state.

일반적으로 각종 기계장치 및 구조물 등의 상호 결합을 위하여 통상적으로 가장 널리 사용되는 것이 볼트와 너트이다. 이러한 볼트와 너트는 그 기계장치 및 구조물의 동작에 의한 진동 및 외부의 충격으로 너트의 나사 체결부분이 점진적으로 풀림 가능성이 있다. 따라서 이를 방지하고자 볼트에 너트를 결합한 후 너트가 풀리는 것을 방지하도록 하는 풀림 방지용 체결볼트가 개발되어 사용되고 있다.In general, the most widely used bolts and nuts for mutual coupling of various machinery and structures, and the like. These bolts and nuts are likely to gradually loosen the threaded portion of the nut due to vibrations and external shocks caused by the operation of the mechanism and structure. Therefore, in order to prevent this, the fastening bolt for loosening prevention to prevent the nut from loosening after coupling the nut to the bolt has been developed and used.

도 1에 도시된 바와 같이 종래의 너트 풀림 방지용 체결볼트(10)는 원통 형태로 형성된 볼트 몸체(11)와 이 볼트 몸체(11)의 상측 외주면에 형성된 나사부(12)를 구비하고, 볼트 몸체(11)의 나사부(12)에 결합되는 너트(15)를 구비한다.As shown in FIG. 1, a conventional nut loosening fastening bolt 10 includes a bolt body 11 formed in a cylindrical shape and a threaded portion 12 formed on an upper outer circumferential surface of the bolt body 11, and the bolt body ( And a nut 15 engaged with the threaded portion 12 of 11).

그리고 볼트 몸체(11)의 상단에는 측방으로 관통한 관통홀(13)이 형성되고, 이 관통홀(13)에는 너트(15)가 체결된 후 너트(15)의 풀림을 방지하도록 하는 별도의 안전핀(14) 또는 와이어가 장착되는 구성으로 되어 있다.And the upper end of the bolt body 11 is formed with a through hole 13 penetrating laterally, the safety hole for preventing the nut 15 from loosening after the nut 15 is fastened to the through hole 13 14 or a structure to which a wire is mounted.

그런데, 이와 같이 종래의 풀림 방지용 체결볼트(10)에서는 안전핀(14) 또는 와이어가 삽입되는 관통홀(13)을 형성시키기 위하여 볼트 몸체(11)의 길이가 필요이상으로 길어진다. 따라서 최초 체결볼트(10)의 제작시 결합에 필요한 길이 이상으로 볼트 몸체(11)를 제작하여야 하므로 그 만큼 체결볼트(10)의 제조단가가 비싸지게 되는 문제점 있다.However, in the conventional fastening bolt 10 for preventing loosening, the length of the bolt body 11 is longer than necessary to form the through-hole 13 into which the safety pin 14 or the wire is inserted. Therefore, when manufacturing the first fastening bolt 10, the bolt body 11 should be manufactured to be longer than the length necessary for the coupling, there is a problem that the manufacturing cost of the fastening bolt 10 is expensive.

본 발명은 전술한 문제점을 해결하기 위한 것으로, 본 발명의 목적은 볼트의 상단에 끼워지는 별도의 리테이너링의 체결로 볼트에 결합된 너트가 풀리는 것을방지할 수 있도록 하는 풀림 방지용 체결볼트를 제공하기 위한 것이다.The present invention is to solve the above-mentioned problems, an object of the present invention to provide a fastening bolt for preventing loosening to prevent the nut coupled to the bolt to loosen by the fastening of a separate retainer ring fitted to the top of the bolt. It is for.

전술한 목적을 달성하기 위한 본 발명에 따른 풀림 방지용 체결볼트는 일측부에 나사부가 형성된 볼트 몸체; 상기 볼트 몸체의 나사부에 체결되는 너트; 상기 볼트 몸체의 상단에 끼워져서 상기 나사부에 체결된 상기 너트의 풀림을 방지하는 리테이너링을 구비한 것을 특징으로 한다.Fastening bolt for preventing loosening according to the present invention for achieving the above object is a bolt body formed with a screw portion on one side; A nut fastened to the threaded portion of the bolt body; It is characterized in that it has a retaining ring which is fitted to the upper end of the bolt body to prevent the loosening of the nut fastened to the screw portion.

그리고 바람직하게 상기 볼트 몸체의 상단에는 상기 리테이너링이 끼워지는 끼움홈이 형성된 것을 특징으로 한다.And preferably the upper end of the bolt body is characterized in that the fitting groove is formed is fitted the retaining ring.

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

도 2와 도 3에 도시된 바와 같이 본 발명에 따른 풀림 방지용 체결볼트(100)는 상단에 상하 소정 폭으로 나사부(111)가 형성된 원통형상의 볼트 몸체(110)와 이 볼트 몸체(110)의 나사부(111)에 체결되는 너트(130)를 구비하고, 볼트 몸체(110)의 상단에 끼워져서 나사부(111)에 체결되는 너트(130)의 풀림을 방지하도록 하는 리테이너링(Retainer ring: 120)을 구비한다.2 and 3, the fastening bolt 100 for preventing loosening according to the present invention has a cylindrical bolt body 110 having a threaded portion 111 formed at a predetermined width up and down at an upper end thereof, and a threaded portion of the bolt body 110. Retainer ring 120 is provided with a nut 130 to be fastened to the 111, and is fitted to the upper end of the bolt body 110 to prevent loosening of the nut 130 fastened to the threaded portion 111. Equipped.

여기서 리테이너링(120)은 일측에 절개부(121)가 형성되어 리테이너링(120)의 내경이 신축 가능하게 형성되어 있고, 내주면은 요철형태로 되어 있다. 한편, 볼트 몸체(110)의 상단에는 리테이너링(120)이 끼워지는 끼움홈(112)이 형성된다.Here, the retainer ring 120 has a cutout 121 formed at one side thereof, and the inner diameter of the retainer ring 120 is elastically formed, and the inner circumferential surface thereof is in an uneven shape. On the other hand, the upper end of the bolt body 110 is formed with a fitting groove 112, the retaining ring 120 is fitted.

이 끼움홈(112)은 필요에 따라 선택적으로 채용될 수 있는 것으로, 끼움홈(112)이 형성되지 않는 경우에는 리테이너링(120)이 볼트 몸체(110)의 나사부 최상단에 체결되도록 함으로써 그 결합이 이루어지도록 할 수 있다.The fitting groove 112 may be selectively employed as necessary. When the fitting groove 112 is not formed, the retaining ring 120 is fastened to the top of the threaded portion of the bolt body 110 so that the coupling thereof is coupled. Can be done.

이하에서는 전술한 바와 같이 구성된 본 발명에 따른 풀림 방지용 체결볼트의 작용상태에 대하여 설명하기로 한다.Hereinafter will be described the working state of the fastening bolt for preventing loosening according to the present invention configured as described above.

본 발명에 따른 너트 풀림 방지용 체결볼트(100)는 볼트 몸체(110)를 소정의 구조물에 대한 체결부위에 설치한 후 볼트 몸체(110)의 상단으로 형성된 나사부(111)에 너트(130)를 삽입하여 체결하면, 볼트 몸체(110)와 너트(130)의 체결이 이루어진다.Fastening bolt 100 for preventing nut loosening according to the present invention, after installing the bolt body 110 to the fastening portion for the predetermined structure insert the nut 130 to the threaded portion 111 formed as the upper end of the bolt body 110 When fastened to, the fastening of the bolt body 110 and the nut 130 is made.

이러한 상태에서 너트(130)의 상측으로 일부 노출된 끼움홈(112)으로 리테이너링(120)을 삽입하여 끼우면 풀림 방지상태로 체결볼트(100)의 결합이 이루어지고, 너트(130)의 상측으로는 볼트 몸체(110)의 노출부분이 최소화된 상태를 유지할 수 있게 된다.In this state, when the retainer ring 120 is inserted into the fitting groove 112 partially exposed to the upper side of the nut 130, the fastening bolt 100 is coupled to the loosening state, and the nut 130 is moved upward. The exposed portion of the bolt body 110 can be maintained in a minimized state.

한편, 리테이너링(120)은 일측에 절개부(121)가 형성되어 있으므로 상술한 바와 같이 끼움홈(112)에 끼워지면 내주면이 끼움홈(112)에 압착됨에 따라 견고한 설치가 이루어지게 된다.On the other hand, since the retaining ring 120 is formed with a cutout 121 at one side, when the fitting ring 112 is fitted into the fitting groove 112 as described above, the inner circumferential surface is pressed into the fitting groove 112, thereby providing a firm installation.

전술한 바와 같이 본 발명에 따른 너트 풀림 방지용 체결볼트(100)는 볼트 몸체(110)의 상단에 별도의 리테이너링(120)을 체결하여 너트(130)의 풀림을 방지하도록 한 것으로, 본 발명의 실시예와 달리 볼트 몸체(110)의 형상과 너트(130)의 형상 그리고 리테이너링(120)의 형상을 일부 변형하여 실시하더라도 기본적으로 본 발명의 필수구성요소들을 포함한 것이라면 모두 본 발명의 기술적 범주에 포함된다고 보아야 한다.As described above, the nut loosening preventing bolt 100 according to the present invention is to prevent loosening of the nut 130 by fastening a separate retainer ring 120 to the top of the bolt body 110. Unlike the embodiment, even if the shape of the bolt body 110 and the shape of the nut 130 and the retainer ring 120 is partially modified, if all the essential components of the present invention included in the technical scope of the present invention It should be considered to be included.

이상과 같은 본 발명에 따른 너트 풀림 방지용 체결볼트는 너트의 체결후 너트의 풀림을 방지하도록 리테이너링을 볼트 몸체의 상단에 형성된 끼움홈에 삽입함으로써 안정적으로 너트의 풀림을 방지할 수 있도록 하고, 이에 따라 불필요하게 노출되는 볼트 몸체의 결합 노출 부분을 최소화함으로써 체결볼트의 크기를 사용에 가장 적합한 상태로 제조할 수 있도록 하여 체결볼트의 제조원가를 절감시킬 수 있도록 하는 효과가 있다.The fastening nut for preventing nut loosening according to the present invention as described above can be stably prevented from loosening the nut by inserting a retaining ring into the fitting groove formed on the top of the bolt body to prevent loosening of the nut after fastening the nut. Accordingly, by minimizing the combined exposure portion of the bolt body that is unnecessarily exposed, it is possible to manufacture the size of the fastening bolt in the most suitable state for use, thereby reducing the manufacturing cost of the fastening bolt.
