Description
본 고안은 고정체를 서로 고정할 때 사용되는 직결나사에 관한 것으로, 특히 직결나사의 회전에 의해서 고정물에 직결나사가 박히는 자리가 형성되는 직결나사에 관한 것이다.The present invention relates to a direct screw that is used to fix the fixtures to each other, and more particularly, to a direct screw that is formed by the rotation of the direct screw screw is a place where the direct screw is embedded.
목재나 철판 및 콘크리트 등의 고정체를 다른 고정체에 고정하기 위해서 사용되는 나사못은 일반못에 비해 견고하게 고정되기 때문에 많이 사용되고 있다.Screws used to fix fixtures such as wood, steel plates and concrete to other fixtures are used more frequently than firmly fixed screws.
그러나, 상기와 같은 나사못을 이용하여 고정체를 고정하기 위해서는 고정체에 나사못이 삽입될 구멍을 미리 형성해야 하기 때문에 고정체를 고정하기 위하여 두번의 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 the fixture, two operations must be performed to fix the fixture. There was a problem of weakening the binding force.
상기와 같은 문제점을 해결하기 위하여 직결나사에 나선형의 절삭날을 형성하여 직결나사가 고정체에 구멍을 형성하면서 직결나사가 고정체에 체결되도록 사용하고 있지만, 직결나사를 회전시켜 체결할 때 직결나사가 회전력에 의해 정위치에서 미끄려지면서 벗어나 엉뚱한 곳에 체결되고, 절삭되는 고정체의 부산물인 절삭밥이 직결나사의 표면에 형성된 절삭홈을 따라 외부로 배출되야 하지만 절삭밥이 외부로 쉽게 배출되지 못하여 부하가 많이 걸려 한번에 체결하지 못하는 문제점이 있었다.In order to solve the above problems, a spiral cutting edge is formed on the direct screw to directly connect the screw to the fixture while the direct screw forms a hole in the fixture, but the screw is rotated when the screw is rotated. Is slipped out of position by the rotational force and is fastened to the wrong place, and the cutting rice which is a by-product of the fixed body to be cut should be discharged to the outside along the cutting groove formed on the surface of the direct screw, but the cutting rice is not easily discharged to the outside. There was a problem that could not be concluded at one time due to too much load.
또한, 직결나사의 머리부를 고정체의 표면이나 내부로 은닉시키기 위하여 머리부에 절삭날을 형성하여 머리부가 고정체에 삽입되도록 형성하고 있지만 머리부에 의해서 절삭된 고정체의 부산물인 절삭밥이 넓적한 머리부에 막히기 때문에 절삭밥이 외부로 배출되지 못하여 머리부가 고정체에 삽입되지 못하는 문제점이 발생하였다.In addition, in order to conceal the head of the direct connection screw into the surface or inside of the fixture, a cutting blade is formed in the head so that the head is inserted into the fixture, but the cutting rice, which is a by-product of the fixture cut by the head, is widely used. Because of the blockage in the head, the cutting rice is not discharged to the outside, and the head cannot be inserted into the fixture.
본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 사용자가 원하는 위치에서 고정체를 절삭하면서 견고하게 고정되는 직결나사를 제공하는 것이다The present invention has been made to solve the above problems, it is to provide a direct screw that is firmly fixed while cutting the fixture at the user's desired position.
본 고안은 고정체가 절삭날에 의해서 절삭되면서 발생되는 부산물인 절삭밥이 배출되지 않고 압축되면서 더욱 견고하게 고정되는 직결나사를 제공하는 것이다.The present invention is to provide a direct screw that is more firmly fixed as the cutting bobbin by-products generated by cutting the cutting edge is not discharged.
또한, 본 고안은 머리부에서 절삭되는 절삭밥이 쉽게 외부로 배출되는 직결나사를 제공하는 것이다.In addition, the present invention is to provide a direct screw which is easily discharged to the cutting bob is cut from the head.
