본 발명은 풀림방지용 특수나사에 관한 것으로서, 보다 상세하게 설명하면 상기 나사는 축방향으로 크게 머리부와 외측으로 나선형의 나사산이 형성되어 있는 몸통부로 나누어지고, 상기 몸통부의 바깥쪽 둘레에는 축방향에 경사진 홈을 방사상으로 2~4개 정도 형성하여 체결이 신속하게 이루어지고, 체결 후 진동이나 충격 등의 외력에 의해 쉽게 풀리지 않도록 한 풀림방지용 특수나사를 제공코자 하는 것이다.The present invention relates to a special screw for preventing loosening, and in more detail, the screw is divided into a body portion in which a helical thread is formed in the head and the outside in a large axial direction, and an outer circumference of the body portion in the axial direction. It is intended to provide fastening prevention screws that are fastened by forming two to four inclined grooves radially and are not easily loosened by external force such as vibration or shock after fastening.

일반적으로 체결용 나사의 경우 대상물에 나사를 체결한 후 진동이나 충격 등의 외력에 의해 나사가 역회전되어 체결이 풀어지는 경우가 빈번하게 발생하여 기계장치 등의 작동오류의 원인이 되었고, 그로 인하여 제품의 불량이나 안전사고의 발생 등으로 이어져 생산 및 안전에 커다란 문제점을 초래하여 왔던 것이다.In general, the screw for fastening the screw is rotated reversely by external force such as vibration or shock after the screw is fastened to the object frequently loosened the fastening, causing the operation error of the mechanical device, etc. It has led to the failure of the product or the occurrence of safety accidents have caused a big problem in production and safety.

종래 풀림방지의 목적을 가지는 나사가 다양하게 개발되었으나, 그 구성이 복잡하고, 생산 공정이 늘어나 전체적으로 생산원가가 높고 판매가격이 고가여서 일부 정밀을 요하는 기계장치나 고가의 제품에 한정되어 사용될 뿐 일반적으로 널리 보편화되지 못하는 문제점을 가지고 있었던 것으로서, 일례로 나사의 머리부 하부에 머리부측으로 역회전방지돌기가 형성된 다각형 와셔를 끼워 체결되도록 한 구성은 와셔의 구성이 복잡하여 제조단가가 상승하고, 다각형 와셔와 일치하는 형상의 홈을 체결 대상물에 형성해야 함으로 제품 전체의 생산 공정이 늘어나는 등의 단점을 가지고 있었고, 다른 실례로 나사의 머리부나 몸통부 단부에 역회전방지수단을 별도로 형성한 구성은 나사를 제조하는 공정이 늘어남과 동시에 제조단가의 앙등을 초래하는 단점을 가지고 있었던 것으로 상기한 바와 같이 보편화시키데 곤란한 문제를 내포하고 있어 상기 문제점들을 해결할 수 있는 특수나사의 필요성이 제반 기술 분야에 절실하였던 것이다.Conventionally, the screw for the purpose of preventing loosening has been developed in various ways, but its configuration is complicated, and the production process is increased, so that the overall production cost is high and the selling price is high, so it is used only for machinery or expensive products requiring some precision. In general, there was a problem that can not be widely universalized, for example, the configuration to fasten the polygon washer formed with the anti-rotation protrusion formed to the head side in the lower part of the head of the screw is complicated by the configuration of the washer to increase the manufacturing cost, The grooves of the shape corresponding to the polygonal washer had to be formed in the fastening object, so the production process of the whole product was increased, and in another example, a configuration in which a reverse rotation prevention means was separately formed at the head or trunk end of the screw Increasing the manufacturing process of screws and at the same time causing the rise of manufacturing cost As a matter of fact, as described above, it contains a problem that is difficult to generalize, and the necessity of a special screw that can solve the above problems is urgently needed in the technical field.

이에 본 발명에서는 상기한 바와 같은 통상의 나사와 종래 풀림방지용 나사의 제반 문제점들을 해결할 수 있는 새로운 구성의 풀림방지용 나사를 창안한 것으로서, 본 발명은 축방향으로 크게 머리부와 외측으로 나선형의 나사산이 형성된 몸통부로 구성된 나사에 있어서, 상기 몸통부의 바깥쪽 둘레에 방사상으로 2~4개 정도의 역회전방지홈을 축방향에 일정 각도로 경사지며 나사산의 골지름까지의 깊이를 갖도록 형성하여 나사체결 시 보다 신속하게 체결이 이루어지도록 하고, 체결 후 진동이나 충격 등의 외력에 의해 나사가 풀리는 것을 방지토록 한 풀림방지용 특수나사를 제공함에 발명의 기술적 과제를 두고 본 발명을 완성한 것이다.Accordingly, the present invention has been invented a new anti-loosening screw that can solve all the problems of the conventional screw and the conventional anti-loosening screw as described above, the present invention is a spiral thread in the head and the outside in the axial direction greatly In the screw consisting of the formed body portion, when the screw is formed by radially circumferentially around the outer portion of the body portion of about 2 to 4 anti-reverse grooves inclined at an angle in the axial direction to have a depth to the valley diameter of the thread The present invention has been completed with the technical problem of the present invention to provide a special screw for fastening to be fastened more quickly and to prevent the screw from loosening by external force such as vibration or shock after the fastening.

본 발명은 축방향으로 머리부(2)와 몸통부(3)로 대분되어 이루어진 나사(1)를 구성함에 있어서, 상기 몸통부(3)의 외측으로는 나선형의 나사산(4)을 일체로 구성하고, 본 발명에서는 상기한 바와 같은 통상의 구성을 갖는 나사(1)의 몸통 부(3) 바깥쪽 둘레에 나사산(4)의 골지름까지의 깊이를 갖는 역회전방지홈(5)을 방사상으로 수개 형성한다.The present invention constitutes a screw 1 composed of the head 2 and the body 3 in the axial direction, and the spiral thread 4 is integrally formed on the outside of the body 3. In the present invention, the reverse rotation preventing groove (5) having a depth to the rib diameter of the screw thread (4) radially around the outer circumference of the trunk portion (3) of the screw (1) having a conventional configuration as described above Form several.

상기 역회전방지홈(5)은 머리부(2)와 몸통부(3)가 이루는 축을 중심으로 θ°로 경사지게 구성하되, θ°는 약 5~15° 정도로 하고, 역회전방지홈(5)은 방사상으로 3개를 형성하되, 3개에 한정하는 것이 아니라 경우에 따라 2개 내지 5개까지 형성할 수 있음은 당연한 것이다.The reverse rotation prevention groove 5 is configured to be inclined at θ ° about the axis formed by the head 2 and the trunk portion 3, the θ ° is about 5 ~ 15 °, the reverse rotation prevention groove (5) Silver forms three radially, but is not limited to three, it is natural that two to five may be formed in some cases.

그리고 상기 나사산(4)을 머리부(2)의 반대 측인 전방으로 치우치게 형성하되, 나사산(4)의 내측 각도를 45°로 형성하여 체결이 보다 용이하게 이루어지도록 한다.And the thread 4 is formed to be biased forward to the opposite side of the head 2, the inner angle of the thread 4 is formed to 45 ° to facilitate the fastening.

도면 중 미 설명부호 6은 나사(1)가 체결되는 대상물을 도시한 것이다.In the drawings, reference numeral 6 shows an object to which the screw 1 is fastened.

상기와 같이 구성되는 본 발명은 통상의 나사(1) 몸통부(3)의 바깥쪽 둘레에 역회전방지홈(5)을 형성하여 나사(1)를 대상물(6)에 체결한 후 진동이나 충격 등의 외력에 의해 나사(1)가 풀리는 것을 방지하여 대상물(6)의 체결이 보다 공고히 되도록 한 것으로서, 이의 작용을 보다 상세히 설명하면 하기와 같다.The present invention constituted as described above is a vibration or shock after forming the anti-rotation groove (5) on the outer circumference of the body portion (3) of the conventional screw (1) to fasten the screw (1) to the object (6) The screw 1 is prevented from being loosened by an external force such as to make the fastening of the object 6 more firm, and its operation will be described in more detail as follows.

우선 나사(1)를 성형할 시 몸통부(3)에 나사산(4)을 전조(thread rolling) 등으로 형성하되, 나사산(4)을 머리부(2)의 반대 측인 전방으로 치우치게 형성하고, 나사산(4)의 내측 각도를 45°로 하여 성형한다. 이 후 몸통부(3)의 바깥쪽 둘레에 방사상으로 3개의 역회전방지홈(5)을 형성하되, 머리부(2)와 몸통부(3)가 이루는 축과 이루는 각을 5~15° 내에서 택일하여 축에 경사지도록 구성하고, 역회전 방지홈(5)의 깊이는 개략 몸통부(3) 나사산(4)의 골지름과 일치시킴이 바람직하지만 필요에 따라 골지름 보다 크게 나사산(4)상에 형성할 수도 있으며, 골지름 보다 작게 몸통부(3) 내측으로 파고 들어가도록 형성할 수도 있는 것이다.First, when forming the screw 1, the thread 4 is formed on the trunk portion 3 by thread rolling or the like, but the thread 4 is formed to be biased forwardly on the opposite side of the head 2, The inside angle of (4) is made into 45 degrees and molded. Thereafter, three reverse rotation preventing grooves 5 are formed radially around the outer portion of the body portion 3, and the angle formed by the shaft formed by the head portion 2 and the body portion 3 within 5 to 15 °. Alternatively, it may be configured to be inclined to the shaft, and the depth of the reverse rotation preventing groove 5 may be approximately equal to the diameter of the valley of the trunk portion 3, the thread 4, but larger than the diameter of the thread 4 as necessary. It may be formed on, or may be formed to dig into the body portion 3 smaller than the rib diameter.

상기 제조방법에 의해 성형된 풀림방지용 특수나사(1)는 대상물(6)에 체결 시 나사산(4)이 전방으로 치우치며 내각이 45° 정도로 형성되어 있으므로 종래의 일반 나사들에 비해 체결 속도가 월등히 높아 체결이 보다 신속하게 이루어지고, 체결이 이루어지고 난 후에는 대상물(6)에 진동이나 충격 등의 외력이 발생하더라도 쉽게 풀리지 않는 것으로서, 그 이유는 외력에 의해 나사(1)가 역회전하려고 할 때 도 4에서 보는 바와 같이 몸통부(3)의 바깥쪽 둘레에 형성된 역회전방지홈(5)에 의해 나사산(4)의 단부가 대상물(6)에 걸려 역회전이 방지되기 때문이며, 그로 인하여 정밀을 요하거나 견고한 체결상태를 유지해야 하는 정밀 내지 고가의 장치에 사용할 시 매우 유용한 것이다.The loosening prevention special screw 1 formed by the manufacturing method has a fastening speed compared to conventional screws because the thread 4 is biased forward and the inner angle is formed at about 45 ° when fastened to the object 6. As the fastening is made faster, and after the fastening is made, it is not easy to loosen even if an external force such as vibration or shock occurs on the object 6, and the reason is that the screw 1 When the end of the screw thread (4) is caught by the object (6) by the reverse rotation prevention groove 5 formed around the outer portion of the body portion 3, as shown in Figure 4, thereby preventing the reverse rotation It is very useful when used in precision or expensive devices that require or maintain a secure fastening condition.

또한 상기 특수나사(1)는 나사산(4)의 내측 각도가 45°로 통상의 나사(1)에 비해 나사산(4)이 약하므로 합성수지 내지 목재로 구성되는 대상물(6)에 주로 많이 사용되지만, 금속으로 이루어진 대상물(6)에도 사용 가능함은 당연한 것이다.In addition, the special screw (1) is mainly used for the object (6) consisting of synthetic resin or wood because the internal thread of the thread 4 is 45 ° compared to the general screw 1 is weaker than the conventional screw (1), Naturally, it can also be used for the object 6 made of metal.

이상에서 상세히 살펴본 바와 같이 본 발명에서 제공하는 풀림방지용 특수나사(1)는 몸통부(3)의 바깥쪽 둘레에 역회전방지홈(5)을 형성하여 나사(1)의 체결을 보다 공고히 하고, 나사산(4)을 전방으로 치우치며 내측 각도를 45°로 성형하여 나사(1)의 체결이 보다 신속하게 이루어지도록 한 것으로서, 진동이나 충격 등의 외력에 의해 나사(1)가 대상물(6)로부터 쉽게 풀리지 않도록 함으로써 정밀을 요하거나 견고한 체결상태를 유지해야 하는 대상물(6)에 매우 유용하고, 나사(1)의 체결작업이 종래의 나사의 체결에 반하여 보다 빨리 이루어져 작업 시간을 단축시키며, 작업효율을 극대화시킬 수 있는 등 그 기대되는 효과가 다대한 발명이다.As described in detail above, the special screw 1 for preventing loosening provided by the present invention forms a reverse rotation preventing groove 5 around the outer portion of the trunk portion 3 to further secure the fastening of the screw 1, The screw 4 is fastened forwardly and the inner angle is formed at 45 ° so that the screw 1 can be fastened. The screw 1 is removed from the object 6 by external force such as vibration or shock. It is very useful for the object 6, which requires precision or maintains a tight fastening state by not being easily loosened, and the fastening work of the screw 1 is made faster than the fastening of the conventional screw, thereby shortening the working time, and working efficiency. It is possible to maximize the expected effect is a great invention.
