본 고안은 고정체를 서로 고정할 때 사용되는 관한 것으로, 특히 나사못의 회전에 의해서 고정물에 나사못이 박히는 자리가 형성되는 나사못에 관한 것이다.The present invention relates to being used when fixing fixtures to each other, and more particularly, to a screw that is formed by the rotation of the screw nails are formed in the seat.
목재나 철판 및 콘트리트 등의 고정체를 다른 고정체에 고정하기 위해서 사용되는 나사못을 일반 못에 비해 견고하게 고정되기 때문에 많이 사용되고 있다.Screws, which are used to fix fixtures such as wood, steel plates, and concrete to other fixtures, are more widely used because they are firmly fixed than general nails.
그러나, 상기와 같은 나사못을 이용하여 고정체를 고정하기 위해서는 고정체에 나사못이 삽입될 구멍을 미리 형성해야 하기 때문에 고정체를 고정하기 위하여 두 번의 작업을 해야하며, 미리 구멍을 천공하기 때문에 나사의 결속력이 약해지는 문제점이 있었다.However, in order to fix the fixture using the screw as described above, since the hole into which the screw is to be inserted must be formed in advance, two operations must be performed to fix the fixture. There was a problem of weakening the binding force.
상기와 같은 문제점을 해결하기 위하여 나사못에 나선형의 절삭날을 형성하여 나사못이 고정체에 구멍을 형성하면서 나사못이 고정체에 체결되도록 사용하고 있지만, 나사못을 회전시키면서 체결시킬 때 나사못이 회전력에 의해서 정위치에서 미끄러지면서 벗어나 엉뚱한 곳에 체결되고, 절삭되는 고정체의 부산물인 절삭밥(chip)이 나사못의 표면에 형성된 절삭홈을 따라 외부로 배출되야 하지만 절삭밥(chip)외부로 쉽게 배출되지 못하는 문제점이 있었다.In order to solve the above problems, a spiral cutting blade is formed on the screw, so that the screw is fastened to the fixing body while the screw forms a hole in the fixing body, but the screw is fixed by the rotational force when the screw is tightened while rotating the screw. The chip, which is a by-product of the fixture being cut off, slips out of position and is cut out, must be discharged to the outside along the cutting groove formed on the surface of the screw, but it is not easily discharged to the outside of the chip. there was.
또한, 나사못의 머리를 고정체의 내부에 은닉시키기 위하여 머리부에 절삭날을 형성하여 머리부가 고정체에 삽입되도록 형성하고 있지만 머리부에 의해서 절삭된 고정체의 부산물인 절삭밥(chip) 넓적한 머리부에 막히기 때문에 절삭밥(chip)이 외부로 배출되지 못하여 머리부가 고정체에 삽입되지 못하는 문제점이 발생하였다.In addition, in order to conceal the head of the screw inside the fixture, a cutting blade is formed in the head so that the head is inserted into the fixture, but a chip wide head is a by-product of the fixture cut by the head. Due to the blockage, the chips are not discharged to the outside, and thus the head cannot be inserted into the fixture.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 사용자가 원하는 위치에서 고정체를 절삭하면서 견고하게 고정되는 나사못을 제공하는 것이다.The present invention has been made to solve the above problems, it is to provide a screw that is firmly fixed while cutting the fixture at a user desired position.
