Description

나사screw

본 고안은 부품등을 조립하거나 고정시키는데 사용하는 나사에 관한 것으로, 더 상세하게는 머리에 있는 홈이 마멸되었을 경우에도 풀림이 가능한 구조로 된 나사에 관한 것이다.The present invention relates to a screw used to assemble or fix parts, and more particularly, to a screw having a structure that can be released even when the groove in the head is worn.

도 1 은 종래의 나사의 사용상태 사시도이다.1 is a perspective view of a state of use of a conventional screw.

나사(10,20)는 산의 모양이나 치수단위에 따라 나눌 수 있으나, 머리(11,21)에 있는 홈을 기준으로 볼 때 +자홈형 나사(10)와 -자홈형 나사(20)로 구분된다.Screws (10, 20) can be divided according to the shape of the mountain or the unit of dimensions, but based on the groove in the head (11, 21) divided into + + groove screw (10) and--groove screw (20) do.

+자홈형 나사(10)는 머리(11)에 +자홈(a)이 형성되어 있어 +자 드라이버(A)로 조이거나 풀 수 있으며, -자홈형 나사(20)는 머리(21)에 -자홈(b)이 형성되어 있어 -자 드라이버(B)로 조이거나 풀 수 있다.+ Self-propelled screw 10 is + head groove (a) is formed on the head (11) can be tightened or loosened with a + screw driver (A),-self-propelled screw (20) is-head (b) is formed so that it can be tightened or loosened by the screwdriver B.

그런데, 이러한 나사(10,20)를 자주 조이고 풀거나 규격에 맞지 않는 드라이버(A,B)로 억지로 체결하는 등으로 인하여 머리(11,21)에 있는 +자홈(a) 또는 -자홈(b)이 마멸되어 나사(10,20)를 풀지 못하는 경우가 종종 있었다. 이러한 경우 나사(10,20)를 억지로 풀려다가 부상을 입기도 하고 부품을 파손시키기도 하였다.However, these screws 10 and 20 are frequently tightened and loosened or forcibly tightened with drivers A and B that do not conform to the specifications, such as + magnetic grooves (a) or-magnetic grooves (b) in the heads 11 and 21. The wear and tear of the screws 10 and 20 were often not possible. In this case, the screws 10 and 20 were forcibly loosened, causing injury and damage to the parts.

본 고안은 이러한 종래의 문제점을 해소하기 위한 것으로, 더 상세하게는 머리에 있는 홈이 마멸되었을 경우에 별도의 드라이버를 사용하여 풀림이 가능한 구조로 된 나사를 제공하는데 있다.The present invention is to solve such a conventional problem, and more particularly to provide a screw having a structure that can be released using a separate driver when the groove in the head is worn.

본 고안은 머리(110,210)에 +자홈(a) 또는 -자홈(b)이 형성된 나사(100,200)에 있어서,The present invention is in the screw (100,200) is formed in the + head groove (a) or-head groove (b) on the head (110,210),

상기 머리(110,210)의 양쪽편에 보조 홈(c)을 형성하여 별도의 드라이버(C)로 풀림이 가능하도록 한 것에 그 특징있다.Auxiliary groove (c) is formed on both sides of the head (110, 210) is characterized in that it can be released by a separate driver (C).

이하, 본 고안의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.

도 2 는 본 고안에 따른 나사의 사용상태 사시도이고, 도 3 은 본 고안에 따른 나사의 사용상태 단면도이다.Figure 2 is a perspective view of the state of use of the screw according to the present invention, Figure 3 is a cross-sectional view of the state of use of the screw according to the present invention.

도 2 에 도시한 바와같이, 2개의 보조 홈(c)은 머리(110,210)의 가장자리를 ㄷ자형으로 절개하여 형성하되, 서로 마주보는 위치에 있도록 한다.As shown in FIG. 2, the two auxiliary grooves c are formed by cutting the edges of the heads 110 and 210 in a c-shape, so as to face each other.

따라서, 나사(100,200)의 머리(110,210)에 있는 +자홈(a)이나 -자홈(b)이 마멸되었을 경우에도 별도로 제작된 드라이버(C)를 사용하여 풀 수 있다.Therefore, the + magnetic groove (a) or the-magnetic groove (b) in the head (110, 210) of the screw (100, 200) can be loosened by using a separately manufactured screwdriver (C).

즉, 별도의 드라이버(C)는 몸통부의 하단을 ㄷ자형으로 형성하여 보조 홈(c)에 끼울 수 있도록 하고, 나사(100,200)에 회전력을 크게 전달시킬 수 있도록 하기 위하여 몸통부를 크랭크형으로 절곡시켜 제작한 것이다.That is, the separate driver (C) is formed by the c-shaped lower end of the body portion to be inserted into the auxiliary groove (c), and to bend the body portion in a crank-type so as to transmit a large rotational force to the screws (100,200) It is produced.

도 3 에 도시한 바와같이, 본 고안에 따른 나사(100,200)가 임의의 부재에 조여진 상태에서 일반적인 드라이버로 푸는 과정에서 +자홈(a) 또는 -자홈(b)이 마멸되었을 경우에 별도로 제작된 드라이버(C)를 사용하여 쉽게 풀 수 있다. 이때 드라이버(C)의 하단의 ㄷ자형 돌기부위를 나사(100,200)의 보조 홈(c)에 끼운 다음 드라이버(C)를 돌리면 나사(100,200)가 풀리게 되며, 이때 풀린 나사(100,200)는 재사용하지 않는 것이 바람직하다.As shown in FIG. 3, the screw 100 or 200 according to the present invention is screwed separately in the case where + magnetic groove (a) or-magnetic groove (b) is worn in the process of loosening with a general screwdriver in a state in which it is fastened to an arbitrary member. It is easy to solve using (C). At this time, insert the c-shaped protrusion at the bottom of the driver (C) into the auxiliary groove (c) of the screws (100,200), and then turn the screwdriver (C) to loosen the screws (100,200). It is preferable.

상술한 바와같이 본 고안에 따른 나사(100,200)는 머리(110,210)의 양쪽편에 보조 홈(c)을 형성하여 이에 적합하게 별도로 제작된 드라이버(C)로 풀림이 가능하도록 한 것으로, 작업자의 부상과 나사(100,200)로 체결된 부품의 파손을 방지할 수 있다.As described above, the screw 100 or 200 according to the present invention forms an auxiliary groove c on both sides of the head 110 and 210 so that the screw 100 and 200 can be loosened by a driver C that is separately manufactured accordingly. And it can prevent the damage of the parts fastened with the screws (100,200).
