Description

풀림방지용 볼트 및 너트{Lock bolt and nut}Lock bolt and nut

본 고안은 풀림방지용 볼트 및 너트에 관한 것으로서, 보다 상세하게는 볼트가 피고정물의 나사공 및 너트에 조여 지므로써, 상호 나산산 각 들에 의해 일측으로 탄성부세하여 피고정물의 진동에 관계 없이 풀림이 방지될 수 있는 풀림방지용 볼트 및 너트에 관한 것이다.The present invention relates to an anti-loosening bolt and nut, and more particularly, because the bolt is tightened to the threaded hole and the nut of the fixed object, the bolt is elastically biased to one side by mutually acidic angles, so that the loosening is performed regardless of the vibration of the fixed object. The present invention relates to bolts and nuts for preventing loosening.

일반적으로 피고정물을 고정하는 볼트 및 너트는, 피고정물의 진동 등에 따라 풀림을 방지할 목적으로 다양하게 제작되어 사용하고 있다.In general, bolts and nuts for fixing a fixed object are variously manufactured and used for the purpose of preventing loosening due to vibration of the fixed object.

특히, 피 고정물 측에 볼트를 나사 체결한 후 너트를 체결하기 전에 풀림방지용 와셔를 삽입하여 볼트의 풀림을 방지하는 방법이 널리 이용되고 있다.In particular, a method of preventing loosening of the bolt by inserting the loosening prevention washer before screwing the bolt on the side of the fixture and then tightening the nut is widely used.

그런데, 이러한 종래 볼트 및 너트의 체결방법에 있어서는 풀림방지 수단을 볼트 및 너트에 부가시켜 형성하지 않고 별도로 제작된 풀림방지용 와셔를 가공하여 볼트 및 너트의 풀림방지용 부속품으로써 별도 제작하여야 하므로, 제작경비의 상승요인을 초래하였으며, 풀림방지 수단이 볼트 및 너트와 별개의 부품으로 이루어진 관계로 사용하기에 불편한 단점이 있었다.By the way, in the conventional method of fastening the bolts and nuts, it is not necessary to add the loosening prevention means to the bolts and nuts to process separately prepared anti-loosening washers, so that they must be manufactured separately as accessories for preventing loosening of the bolts and nuts. It caused an upward factor, there was a disadvantage in that it is inconvenient to use because the loosening prevention means is composed of a separate part from the bolt and nut.

따라서 본 고안의 목적은, 하나의 볼트 및 너트의 동체에 풀림방지용 수단을 직접 설치함으로써, 하나의 체결구로서도 풀림을 효율적으로 방지할 수 있는 풀림방지용 볼트 및 너트를 제공하는 것이다.Accordingly, an object of the present invention is to provide an anti-loosening bolt and nut that can effectively prevent loosening even as one fastener by directly installing an anti-loosening means on the body of one bolt and nut.

도 2는 도 1에 따른 A부분 확대 단면도이다.2 is an enlarged cross-sectional view of portion A of FIG. 1.

상기 목적은, 본 고안에 따라, 피 고정물을 체결하는 볼트 및 너트에 있어서, 일정피치와 골지름을 두고 나선상으로 형성된 나사산 각의 외경부에, 중심부를 향하도록 양측으로 부터 내측으로 경사지도록 삭설된 홈을 형성한 것을 특징으로 하는 풀림방지용 볼트 및 너트에 의하여 달성된다.The object is, according to the present invention, in the bolt and nut for fastening the fixed object, in the outer diameter portion of the screw angle formed in a spiral with a constant pitch and a rib diameter, cut inclined inward from both sides toward the central portion It is achieved by a bolt and nut for preventing loosening, characterized in that the groove is formed.

이하에서는, 첨부된 도면을 참조하여 본 고안에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail the present invention.

도 1은 본 고안에 따른 풀림방지용 볼트 및 너트를 일부 절결항 상태의 측면도이며, 도 2는 도 1에 따른 A부분 확대 단면도이다. 이들 도면에 도시되어 있는 바와같이 본 고안의 풀림방지용 볼트(11) 및 너트(13)는, 일정피치(15)를 두고 나선상으로 나사산 각(17)을 형성하고 있다.1 is a side view of a part of the state of the loosening prevention bolts and nuts according to the present invention, Figure 2 is an enlarged cross-sectional view of the portion A according to FIG. As shown in these figures, the bolt 11 and the nut 13 for preventing release of the present invention form a thread angle 17 in a spiral shape with a constant pitch 15.

나사산 각(17)의 외경부(19)에는 중심부를 향하는 홈(21)을 삭설한다.In the outer diameter part 19 of the thread angle 17, the groove 21 toward the center is cut.

즉, 외경부(19)의 중심부를 깃점으로 양측으로 부터 외경부의 중심부를 향하는 경사각을 형성함으로써 소정의 깊이로 홈(21)이 형성된다. 따라서, 볼트(11)가 축선 방향으로 회전하면서 체결될 때, 홈(21)에 의하여 볼트(11) 및 너트(13)의 나사산 각(17,17a)에 당접된 나사산 각(17,17a)들은 일측으로 상호 탄성부세하게 구성된다.That is, the groove 21 is formed to a predetermined depth by forming an inclination angle from both sides toward the central portion of the outer diameter portion 19 as a flag point. Therefore, when the bolt 11 is tightened while rotating in the axial direction, the thread angles 17, 17a abutted by the grooves 21 on the thread angles 17, 17a of the bolt 11 and the nut 13 are It is configured to elastically bias each other.

이와 같이 구성된 본 고안의 볼트(11) 및 너트(13)는, 피고정물(30)을 고정하는 체결구로 사용되며, 이때, 볼트(13) 만을 사용하여 피고정물(30)을 체결할 때에는, 피고정물(30)에 형성된 나사공에 축선방향으로 부터 볼트(11)를 회전시켜 체결하게 되면 나사공에 형성된 나사산 각에 당접되는 볼트(11)의 나사산 각(17)과 당접된다.The bolt 11 and the nut 13 of the present invention configured as described above are used as fasteners for fixing the to-be-fixed object 30. In this case, when fastening the to-be-fixed object 30 using only the bolt 13, the defendant When the bolt 11 is rotated and fastened to the screw hole formed in the still life 30, the screw 11 is abutted with the thread angle 17 of the bolt 11 abutting against the thread angle formed in the screw hole.

따라서, 당접되는 볼트(11)의 나사산 각(17)의 외경부(19)에 형성된 홈(21)이 일측으로 밀림되면서 체결되며 체결완료된 상태의 나사산 각(19)은 다시 외측으로 탄성부세 함으로써 상호 당접되어 피고정물(30) 등의 진동에 관계 없이 풀림이 방지된다.Accordingly, the groove 21 formed in the outer diameter portion 19 of the thread angle 17 of the bolt 11 to be contacted is pushed to one side, and the thread angle 19 in the fastened state is elastically urged to the outside again. The abutment is prevented from loosening irrespective of vibration of the fixed object 30 and the like.

한편, 볼트(11)와, 너트(13)를 동시에 사용하는 경우에는 피고정물(30)의 나사공에 축선방향으로 부터 회전시켜 피고정물(30)을 관통 고정시킨 후 너트(13)를 고정하면, 고정되는 너트(13)의 나사공에 형성된 나사산 각(17a)과 볼트(11)에 형성된 나사산 각(17)이 상호 당접되면서 일측으로 탄성부세 함으로써, 볼트(11) 및 너트(13)는 상호 버팀되므로 풀림이 방지된다.On the other hand, when the bolt 11 and the nut 13 are used at the same time, if the nut 13 is fixed after the fixed object 30 is fixed through the screw hole of the fixed object 30 by rotating from the axial direction. The bolt 11 and the nut 13 are mutually elastically urged to one side while the thread angle 17a formed in the screw hole of the nut 13 to be fixed and the thread angle 17 formed in the bolt 11 abut each other. Since it stops, loosening is prevented.

본 고안은 전술한 실시예와는 달리, 나사산 각의 양측으로 부터 내측으로 경사지도록 삭설된 홈을 형성하지 않고, 나사산 각의 중앙부로 부터 내측을 향하도록 요입된 홈 또는 그와 유사한 형상으로써, 함께 체결되는 너트 및 피 고정물의 나사산 각에 당접된 후 내외 측으로 탄성부세할 수 있는 형상으로도 본 고안의 목적을 달성할 수도 있다.The present invention, unlike the embodiment described above, does not form a groove inclined inwardly from both sides of the thread angle, but is a groove or similar shape recessed to face inwardly from the central portion of the thread angle. The object of the present invention may also be achieved in a shape that can be elastically urged to the inside and the outside after being abutted on the thread angle of the nut and the fixture to be fastened.

이상 설명한 바와같이 본 고안에 따르면, 볼트 및 너트의 동체에 직접적으로 풀림방지 수단을 설치 함으로써, 사용이 편리한 이점이 있으며, 특히, 볼트 및 너트의 풀림방지수단을 종래와 달리 별도의 풀림방지수단용 부품으로 제작할 필요가 없어 생산성 향상과 더불어 원가를 절감할 수 있는 풀림방지용 볼트 및 너트가 제공된다.As described above, according to the present invention, by providing the anti-loosening means directly to the fuselage of the bolt and nut, there is an advantage that it is convenient to use, and in particular, the anti-loosening means of the bolts and nuts is separate for Since there is no need to manufacture parts, bolts and nuts are provided to prevent loosening and increase productivity.
