Description

풀림방지용 볼트{Bolt for preventing loosening}Bolt for preventing loosening

본 발명은 풀림방지용 볼트에 관한 것으로서, 특히 볼트 몸체의 일정 부위까지는 오른 나사가 형성되고, 연속되는 나머지 일정 부위까지는 왼 나사가 형성되며, 각 오른 나사 형성부 및 왼 나사 형성부에는 각각 그에 상응하는 너트가 체결됨으로써 볼트와 너트의 체결상태가 진동 등에 의해 쉽게 풀리는 것을 방지할 수 있는 풀림방지용 볼트에 관한 것이다.The present invention relates to an anti-loosening bolt, and in particular, a right screw is formed to a predetermined portion of the bolt body, and a left screw is formed to the remaining predetermined portion of the bolt, and each right screw forming portion and the left screw forming portion respectively correspond to each other. The present invention relates to an anti-loosening bolt which can prevent the fastening state of the bolt and the nut from being easily loosened by vibration.

일반적으로, 볼트와 너트는 물체를 결합 및 체결하는 수단으로서 널리 사용되고 있으며, 물체를 견고하게 체결하여 쉽게 해제되지 않도록 하는 것을 하나의 목적으로 하고 있다.In general, bolts and nuts are widely used as a means for engaging and fastening an object, and one object is to securely fasten an object so that it is not easily released.

그러나, 볼트 및 너트는 물체 자체의 흔들림이나 떨림, 혹은 외부의 물리적 충격과 기온의 변화에 의한 신축성 등의 발생으로 체결력이 감소되고 이러한 외적인 현상으로 자연히 풀림현상이 발생되는 경우가 많다. 이러한 풀림, 즉 체결된 상태에서의 역회전을 방지하기 위하여 종래에는 여러 종류의 체결수단이 강구된 바 있다. 그 중의 하나로서 와셔(washer)를 들 수 있고, 그 와셔에서도 스프링 와셔 이붙이, 플레인, 와셔붙이너트 등이 있으며, 또 한편으로는 홈붙이리머(fluted reamer), 또는 너트에 홈이나 통공을 뚫어 분할핀(split pin)을 체결하거나 상기 홈붙이리머에 스냅링(snap ring)을 체결하여 고정하는 구성 등을 불 수 있다.However, bolts and nuts have a fastening force due to shaking or shaking of the object itself or elasticity due to external physical shocks and temperature changes, and the external phenomenon often causes loosening. In order to prevent such loosening, that is, reverse rotation in the fastened state, various kinds of fastening means have been devised in the related art. One of them is a washer, which also includes spring washer teeth, plains, and washer nuts, and on the other hand, a fluted reamer or a nut having a groove or a hole Fastening a split pin or fastening a snap ring to the grooved reamer may be fixed.

그런데, 이상과 같은 종래의 구성들은 어느 정도 효과가 있기는 하나, 충분히 만족할 만한 수준은 못되고 있다. 즉, 상기 와셔는 풀림을 방지한다고 하나 그 효과가 크지 못하고, 단순히 와셔가 가지고 있는 약간의 신축성으로 볼트 또는 피체결체의 떨림과 신축성을 와셔의 신축으로 감소시킴으로써 급속한 풀림을 방지하는 정도에 지나지 않고 있다. 또한, 분할핀에 의한 수단에서는 그 효과가 볼트와 너트의 완전한 분리가 없을 뿐이지 볼트 또는 너트의 풀림을 원천적으로 방지할 수 있는 구조로 되어 있지는 않다.However, the above-described conventional configurations, although effective to some extent, are not sufficiently satisfactory. In other words, the washer prevents loosening, but its effect is not great, and it is only a slight elasticity of the washer to prevent the rapid loosening by reducing the vibration and elasticity of the bolt or fastened body to the elasticity of the washer. . In addition, the effect of the split pin does not have a complete separation of the bolt and nut, but does not have a structure that can prevent the loosening of the bolt or nut.

그리고, 새로운 구성으로서는 너트에 톱니를 일체로 구성한 와셔를 일체로 하여 물체와의 결합성을 증대하거나, 와셔와 같이 병행된 톱니로서 풀림을 억제하고 있으나, 이들 역시 전술한 와셔에서 경미하게 진보된 정도이고, 그 효과면에서 확연한 차이를 보여주지 못하고 있다.In addition, in the new configuration, the nut is integrally equipped with a washer integrally increasing the bondability with the object, or the loosening is suppressed as a parallel tooth like the washer, but these are also slightly advanced in the washer described above. It does not show a significant difference in terms of the effect.

이상과 같은 볼트와 너트의 체결 구조에 있어서, 체결상태가 쉽게 풀리지 말아야 하는 것은 매우 중요한 요소이다. 특히, 기계류, 자동차, 항공기 등 진동이 많은 구성물에서 체결 볼트 또는 너트의 체결상태가 느슨해지면 각 구성 장치들의 체결물이 이완되고, 이러한 비정상적인 결합상태에서의 운동은 작동불량이 발생되기 쉽고 그 성능을 제대로 발휘하지 못함으로써 고장의 요인이 됨과 동시에 사고의 위험성이 따르게 된다.In the above-described fastening structure of the bolt and nut, it is very important that the fastening state should not be easily released. In particular, when the fastening state of the fastening bolt or nut is loosened in the vibration-rich components such as machinery, automobiles, and aircrafts, the fastenings of the respective components are relaxed, and movements in such abnormal coupling states are likely to cause malfunctions Failure to do so can lead to failure and risk of an accident.

본 발명은 상기와 같은 사항을 감안하여 창출된 것으로서, 하나의 볼트 몸체에 오른 나사와 왼 나사가 모두 형성되고, 그 오른 나사 형성부 및 왼 나사 형성부에는 각각 그에 상응하는 너트가 체결됨으로써 진동 등에 의해 볼트와 너트의 체결상태가 풀리는 것을 방지할 수 있는 풀림방지용 볼트를 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned matters, and both the right screw and the left screw are formed in one bolt body, and the corresponding screw is fastened to the right screw forming part and the left screw forming part, respectively. It is an object of the present invention to provide an anti-loosening bolt that can prevent the bolt and nut from being loosened.
