본고안은 둥근머리 볼트용 원형렌치에 관한 것으로서, 더욱 상세하게는 둥근머리볼트의 측면과 상면을 동시에 가압하여 볼트를 풀고 조일 수 있게 함과 동시에 크기가 다른 각종 둥근머리 볼트에 맞게 원형렌치를 교체할 수 있도록 하는 둥근머리 볼트용 원형렌치에 관한 것이다.This paper relates to a round wrench for round head bolts. More specifically, it is possible to simultaneously press the side and top of the round head bolts to loosen and tighten the bolts and to replace the round wrenches for various round head bolts of different sizes. It relates to a round wrench for round head bolts.
일반적으로, 둥근머리 볼트는 “―”자 드라이버나 “+”자 드라이버를 이용하여 볼트머리 상면에 형성된 각 형상에 맞대어 가압하고 회동시키므로서 볼트를 풀거나 조였었다.In general, round head bolts have been loosened or tightened by using a “-” screwdriver or a “+” screwdriver to press and rotate against each shape formed on the top of the bolt head.
그러나, 볼트의 재질은 드라이버의 재질에 비해 약해 볼트 머리에 형성된 각종 형상이 손상되어 볼트 자체를 못쓰게 되는 경우가 허다할 뿐 아니라 볼트의 초기 해제동작에 의한 무리한 드라이버의 가압회동력으로 볼트의 형상으로부터 이탈되어 작업자가 부상을 입거나 근접된 부품이 파손되는 경우 또한 빈번히 발생되었다.However, the material of the bolt is weaker than the material of the driver, and the various shapes formed on the head of the bolt are damaged and the bolt itself can not be used as well. Frequent breakouts have caused workers to injure or break adjacent parts.
한편, 종래의 렌치에 있어서, 상기 렌치는 그 사용범위가 단지 육각머리 볼트에 국한되어 둥근머리 볼트에는 전혀 사용하지 못하는 사용상의 문제점이 발생되었다.On the other hand, in the conventional wrench, the use of the wrench is limited to only the hexagon head bolt, the use problem that can not be used at all round head bolt has occurred.
따라서, 본고안은 상기와 같은 제반 문제를 해결하기 위해 안출된 것으로서, 그 목적은 둥근머리 볼트의 측면과 상면을 가압과 동시에 회동시켜 볼트를 풀고 조일 수 있게 함과 동시에 크기가 다른 각종 둥근머리 볼트에 맞게 원형렌치를 교체할 수 있도록 하는 둥근머리 볼트용 원형 렌치를 제공함에 있다.Accordingly, the present invention has been devised to solve the above problems, and its purpose is to rotate the side and top surfaces of the round head bolts at the same time to release and tighten the bolts, and at the same time, various round head bolts of different sizes. It is to provide a round wrench for round head bolts to replace the round wrench.
상기 목적을 달성하기 위해 본고안은 손잡이부와 지지간으로 구성된 공지의 둥근머리 볼토용 공구에 있어서, 상기 지지간의 끝단에 소정크기의 내경을 갖고 그 내주면 일측에 키이가 형성된 끼움부를 부설하고, 상기 끼움부의 내주면에 면접촉되고 키이에 대향되게 끼우는 키이홈이 형성된 원형렌치부를 구비하되, 그 내부에 볼트의 상면과 측면을 가압하는 상면 압착부와 측면압착부를 상형하광되게 형성하여 된 특징을 갖는다.In order to achieve the above object, the subject of the present invention is a well-rounded round head toe tool composed of a handle portion and a support, which has an inner diameter of a predetermined size at the end of the support and lays a fitting portion formed with a key on one side of the inner circumferential surface thereof. It is provided with a circular wrench formed with a key groove that is in contact with the inner circumferential surface of the fitting portion and the key groove is opposed to the key, and has an upper surface pressing portion and a side pressing portion for pressing the upper surface and the side of the bolt therein.
이하, 본고안을 첨부한 도면에 의거하여 보다 상세하게 설명한다.EMBODIMENT OF THE INVENTION Hereinafter, it demonstrates in detail based on attached drawing of this specification.
제 1 도는 본고안에 따른 둥근머리 볼트용 원형렌치를 도시한 분리사시도이고, 제 2 도는 결합된 상태의 본고안을 도시한 측단면도로서, 손잡이부(10)와 지지간(12)으로 구성된 공지의 둥근머리 볼트용 공구에 있어서, 상기 지지간(12)의 끝단에 소정크기의 내경을 갖고 그 내주면 일측에 돌출되는 키이(14)가 형성된 끼움부(16)를 형성한다.FIG. 1 is an exploded perspective view showing a round wrench for a round head bolt according to the present invention, and FIG. 2 is a side cross-sectional view showing the present idea in a coupled state, which is a well-known part composed of a handle portion 10 and a support 12. In the round head bolt tool, a fitting portion 16 having an inner diameter of a predetermined size at the end of the supporting rod 12 and having a key 14 protruding from one side of the inner circumferential surface thereof is formed.
한편, 상기 끼움부(16)의 내주면에 면접촉되고 가압회동에 의해 제0자리에서 헛돌지 않게 하기 위해 키이(14)에 맞춰 대향되게 끼우는 키이홈(24)이 형성된 원형렌치부(20)를 구비하되, 상기 원형렌치부(20)의 내부에 볼트의 상면과 측면을 가압하는 상면압착부(26)와 측면압착부(28)를 그 내경이 상부에서 하부로 향할수록 크게 형성하여 된 것이다.Meanwhile, the circular wrench 20 having the key groove 24 formed to face the inner circumferential surface of the fitting portion 16 so as to face the key 14 so as not to be unstable at the zero position by the pressure rotation is formed. It is provided, but the inner side of the circular wrench 20, the upper pressing portion 26 and the side pressing portion 28 for pressing the upper surface and the side of the bolt is formed so as to increase the inner diameter from the upper side to the lower side.
한편, 상기 상면압착부(26)와 측면압착부(28)상에는 볼트와의 마찰력을 증대시키기 위해 미세돌기(29)를 압착부(26)(28)전면에 형성하여 된 것이다.On the other hand, on the upper pressing portion 26 and the side pressing portion 28 is formed a fine protrusion 29 on the front of the pressing portion 26, 28 in order to increase the friction between the bolt.
또한, 모듈화된 다양한 둥근머리 볼트의 치수에 맞게 상면압착부(26)와 측면압착부(28)를 형성한 원형렌치부(20)를 여러개 구비하여 선택적으로 사용할 수 있다.In addition, it is possible to selectively use a plurality of circular wrench 20 formed with a top pressing portion 26 and a side pressing portion 28 to fit the dimensions of the various round head bolts modularized.
상기와 같이 구성된 본고안의 작동상태를 설명한다.The operating state of the present invention configured as described above will be described.
볼트를 체결하거나 해체시키기 위해 지지간(12) 일측의 끼움부(16)내경으로 그 볼트의 머리부의 치수에 대향되는 원형렌치부(20)를 끼움부(16)의 내주면에 원형렌치부(20)의 외주면이 면접촉되게 끼우되, 상기 끼움부(16)의 키이(14)와 원형렌치부(20)의 키이홈(24)이 서로 결합될 수 있도록 한다.Circular wrench 20 on the inner circumferential surface of the fitting portion 16 is fitted with a circular wrench portion 20 opposite the dimensions of the head of the bolt with the inner diameter of the fitting portion 16 on one side of the support rod 12 to fasten or dismantle the bolt. The outer circumferential surface of the) is fitted in surface contact, so that the key 14 of the fitting portion 16 and the key groove 24 of the circular wrench 20 can be coupled to each other.
이후, 원형렌치부(20) 내부의 상면 압착부(26)와 측면압착부(28)를 볼트의 둥근머리의 상면으로 완전히 덮혀질 수 있도록 끼워 수직 가압력과 동시에 회동력을 가한다.Thereafter, the upper pressing portion 26 and the side pressing portion 28 inside the circular wrench 20 are inserted to be completely covered by the upper surface of the round head of the bolt, and apply rotational force simultaneously with the vertical pressing force.
한편, 원형렌치부(20)의 상면압착부(26)와 측면압착부(28)의 전면에는 회동력에 따른 마찰력을 증대시키기 위해 형성한 미세돌기(29)에 의해 볼트를 쉽게 체결 또는 해제시킬 수 있다.On the other hand, on the front of the upper pressing portion 26 and the side pressing portion 28 of the circular wrench 20, the bolt is easily fastened or released by the fine protrusion 29 formed to increase the frictional force due to the rotational force. Can be.
