본 고안은 기계나 장치 등의 각종 부품을 서로 체결시킬 때에 사용되는 렌치보울트와 그 렌치에 관한 것으로, 특히 적은 힘으로도 용이하게 조이거나 풀어줄 수 있도록 된 렌치보울트와 그 렌치에 관한 것이다.The present invention relates to a wrench bolt and a wrench used when fastening various parts such as a machine or an apparatus, and more particularly, to a wrench bolt and a wrench that can be easily tightened or loosened with a small force.

일반적으로 렌치보울트는 기계나 장치의 부품을 분리가능하게 체결시킬 때에 널리 사용되고 있는 바, 특히 스패너로 보울트를 풀거나 조이기가 어려운 경우나 보울트의 머리부가 가능한 한 돌출되지 않도록 하는 경우에 렌치보울트가 사용되고 있다.In general, wrench bolts are widely used to detach parts of a machine or apparatus. In particular, wrench bolts are used when it is difficult to loosen or tighten a bolt with a spanner, or to prevent the head of the bolt from protruding as much as possible. have.

이와 같은 종래의 렌치보울트는 제6도(a) 및 (b)에 도시된 것과 보울트 머리부(1)에 렌치삽입홈(1a)이 형성됨과 더불어 상기 머리부(1)에 나사부(2)가 일체로 연장형성된 구조로 되어 있다.Such a conventional wrench bolt has a wrench insertion groove 1a formed in the bolt head 1 as shown in FIGS. 6 (a) and 6 (b), and a screw portion 2 is provided on the head 1. It has an integrally extended structure.

이에 따라 렌치보울트를 풀거나 조이고자 할 경우에는 통상 ㄱ자형상으로 절곡된 육각렌치의 끝부위를 상기 렌치삽입홈(1a)에 삽입해서 시계 또는 반시계방향으로 회전시키면, 그 회전토오크에 의해 렌치보울트가 풀리거나 조여지게 된다.Accordingly, in order to loosen or tighten the wrench bolt, insert the end portion of the hexagon wrench bent into a L shape into the wrench insertion groove 1a and rotate it clockwise or counterclockwise, and the wrench bolt is rotated by the torque. Will be loosened or tightened.

그런데 상기한 종래 렌치보울트는 그 렌치삽입홈(1a)에 꼭맞는 렌치를 삽입해서 회전시켜야만이 렌치보울트를 풀거나 조일수가 있게 된다. 즉 만일에 상기 렌치삽입홈(1a)이 빈번한 체결로 혹은 오랫동안 사용해서 삽입홈(1a)벽의 일부가 마모되거나 하게 되면, 삽입홈(1a)의 형상과 렌치의 끝부위 형상이 일치되지 않게 되기 때문에 렌치를 삽입해서 회전시켜도 렌치가 삽입홈(1a) 내에서 헛돌게 되어 렌치보울트를 풀거나 조이기가 극히 어렵게 되는 결점이 있었다.However, the above-mentioned conventional wrench bolt can be released or tightened only by inserting and rotating a wrench fitted in the wrench insertion groove 1a. That is, if the wrench insertion groove 1a is worn frequently or used for a long time, part of the wall of the insertion groove 1a wears out, the shape of the insertion groove 1a does not match the shape of the end of the wrench. For this reason, even when the wrench is inserted and rotated, the wrench turns in the insertion groove 1a, so that it is extremely difficult to loosen or tighten the wrench bolt.

이에 본 고안은 상기한 종래 렌치보울트의 결점을 해소하기 위해 안출된 것으로, 적은 힘으로도 쉽게 풀거나 조여줄 수 있고 렌치삽입홈이 마모되어도 체결시킬 수 있도록 된 렌치보울트와 그 렌치를 제공함에 그 목적이 있다.The present invention has been made to solve the drawbacks of the above-mentioned conventional wrench bolt, it is easy to loosen or tighten with a small force and to provide a wrench bolt and the wrench that can be fastened even if the wrench insertion groove is worn. There is a purpose.

상기한 바의 목적을 달성하기 위한 본 고안에 따른 렌치보울트는, 보울트 머리부에 육각형상의 렌치삽입홈이 형성됨과 더불어 상기 머리부에 나사부가 일체로 연장형성되는 한편, 상기 보울트머리부의 상면에는 삽입홈으로 부터 외측면까지 소정 높이로 돌출된 리브가 연장형성된 구조로 되어 있다.Wrench bolt according to the present invention for achieving the object of the bar, the hexagonal wrench insertion groove is formed in the bolt head portion and the screw portion is integrally formed on the head portion, while being inserted into the upper surface of the bolt head portion The ribs protruding from the grooves to the outer side at a predetermined height extend.

또 본 고안에 따른 렌치는 한쪽 측면모서리를 따라 렌치의 끝부위로 부터 몸체안쪽으로 렌치삽입홈의 깊이만큼 들어간 위치에 리브가 연장형성된 구조로 되어 있다.In addition, the wrench according to the present invention has a structure in which a rib extends from a tip of the wrench along one side edge to the depth of the wrench insertion groove into the body.

이에 따라 렌치보울트의 나사부에 적은 힘으로도 큰 토오크를 가할 수 있기 때문에 렌치보울트를 용이하게, 풀거나 조일수 있을 뿐만 아니라, 렌치삽입홈이 마모되더라도 상기 리브와 상응하는 리브가 측면모서리에 형성된 렌치를 삽입해서 풀거나 조일수가 있게 된다.As a result, a large torque can be applied to the threaded portion of the wrench bolt, so that the wrench bolt can be easily unscrewed or tightened. In addition, even if the wrench insertion groove is worn, the rib corresponding to the rib is inserted into the side edge. You can loosen or tighten.

이하 본 고안을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도(a)는 본 고안의 1실시예에 따른 렌치보울트의 평면도이고, 제1도(b)는 그 a-a선 단면도인 바, 보울트머리부(1)에 육각형상의 렌치삽입홈(1a)이 형성됨과 더불어 상기 머리부(1)에 나사부(2)가 일체로 연장형성되는 한편, 상기 보울트머리부(1)의 상면에는 삽입홈(1a)으로 부터 외측면까지 소정 높이로 돌출된 리브(1b)가 연장형성된 구조로 되어 있다.Figure 1 (a) is a plan view of a wrench bolt according to an embodiment of the present invention, Figure 1 (b) is a cross-sectional view of the line aa, the hexagonal wrench insertion groove (1a) in the bolt head (1) In addition, while the threaded portion 2 is integrally formed on the head portion 1, the rib portion protruding from the insertion groove 1a to the outer surface on the upper surface of the bolt head portion 1 is formed. 1b) has an extended structure.

상기한 구조로 된 렌치보울트를 효과적으로 풀거나 조이기 위해서는 제2도에 도시된 것과 같이, 렌치(3)의 한쪽 측면모서리를 따라 렌치의 끝부위로 부터 몸체안쪽으로 렌치삽입홈(1a)의 깊이(h)만큼 들어간 위치에 리브(3a)가 연장형성된 렌치(3)가 바람직하다.In order to effectively loosen or tighten the wrench bolt of the above structure, as shown in FIG. 2, the depth of the wrench insertion groove 1a into the body from the end of the wrench along one side edge of the wrench 3 ( It is preferable that the wrench 3 in which the rib 3a extended in the position which entered by h).

이는 렌치(3)의 끝부위가 삽입홈(1a)에 삽입된 상태에서 렌치(3)의 리브(3a)가 렌치보울트의 머리부에 형성된 리브(1b)에 닿도록 하며, 렌치를 돌려서 보울트를 풀거나 조일때에 렌치(3)의 리브(3a)와 렌치보울트의 리브(1b)에 의해서도 토오크가 가해져 보울트를 쉽게 풀거나 조일수가 있게 되고, 또 만일에 렌치삽입홈(1a)이 마모되어 렌치의 끝부위와 렌치삽입홈(1a)의 칫수가 꼭맞지 않게 되어 렌치가 헛돌게 되더라도 상기 리브(3a, 1b)에 가해지는 토오크만으로도 렌치보울트를 쉽게 풀거나 조일수 있게 된다.This allows the rib 3a of the wrench 3 to contact the rib 1b formed on the head of the wrench bolt, with the tip of the wrench 3 inserted into the insertion groove 1a. When loosening or tightening, the torque is also applied by the rib 3a of the wrench 3 and the rib 1b of the wrench bolt, so that the bolt can be easily released or tightened, and if the wrench insertion groove 1a is worn out, the wrench Even if the end of the wrench insertion groove (1a) dimensions do not fit snugly, even if the wrench turns out, the torque applied to the ribs (3a, 1b) can be easily released or tightened the wrench bolt.

한편 제3도는 본 고안 2실시예에 따른 렌치보울트의 평면도인 바, 렌치보울트의 나사부(2)에 가해지는 토오크를 증대시키기 위해 2개의 리브(1b)가 형성된 구조이고, 제4도 및 제5도도 역시 토오크를 증대시키기 위해 3개 및 4개의 리브(1b)가 각각 형성된 구조이다.3 is a plan view of the wrench bolt according to the second embodiment of the present invention, in which two ribs 1b are formed to increase torque applied to the threaded portion 2 of the wrench bolt, and FIGS. 4 and 5 The figure is also a structure in which three and four ribs 1b are formed to increase torque, respectively.

이상 설명한 바와 같이 본 고안에 따른 렌치보울트에 의하면, 렌치보울트에 적은 힘을 가해서도 용이하게 풀거나 조일수 있을 뿐만 아니라 렌치삽입홈이 마모되어도 쉽게 풀거나 조일 수가 있는 효과가 있다.As described above, according to the wrench bolt according to the present invention, the wrench bolt can be easily loosened or tightened even with little force, and the wrench insertion groove can be easily loosened or tightened even when the wrench insertion groove is worn.
