Abstract

PURPOSE: A hammer drill is provided to easily drive a nail into the concrete by using a hole formed via an impactor. CONSTITUTION: A cylindrical casing(3) is integrated with a body(1) having a grip(2). A threaded portion(7) and a spring hole(8) are formed in the middle of an impactor(5) of which protrusions(6) are fitted into guide grooves(4) of the casing. Another threaded portion(9) is formed on the outer face of the threaded portion of the impactor, and another spring hole(12) is formed in the upper end of a rotating chuck(10) moving up and down with response to up and down movement of the impactor. A cap(14) is combined to the lower end of the body to prevent separation of the impactor and the rotating chuck. For driving a nail or a hanger, a drill(13) of the body is placed at a desired position. While the grip is held, the protruded portions of the impacts are hit. The impactor moves downwardly by the hitting shock, and the protrusions of the impactor move down linearly while being fitted into the guide grooves. Since the threaded portions are engaged with each other, the rotating chuck rotates by the linear movement of the impactor. When the rotating chuck rotates downwardly, the frill fixed in a fixing hole(11) forms a hole in a wall or a panel.

Description

해머 드릴{.}Hammer drill {.}

본 발명은 해머 드릴에 관한 것으로, 특히 손잡이를 잡고 임팩터를 망치로 치면 케이싱의 내부에서 직선의 왕복운동을 하는 임펙터의 내면에 형성한 나사선에 외면의 나사선이 치합되는 회전척이 드릴을 회전시키는 중에 밀어주어 콘크리트에 작은 직경의 홀을 형성할 수 있도록 함으로써 적은 힘으로 형성한 구멍을 이용하여 콘크리트 못을 쉽게 박을 수 있도록 한 해머 드릴에 관한 것이다.The present invention relates to a hammer drill, in particular a rotary chuck in which a screw thread on the outer surface is engaged with a screw thread formed on the inner surface of the impactor which linearly reciprocates in the casing when the impactor is hammered by the handle. The present invention relates to a hammer drill that can be easily pushed into a concrete nail by using a hole formed with a small force by pushing it to form a small diameter hole in the concrete.

일반적으로 현대의 건축물은 콘크리트로 튼튼하게 건축하여 장기간 안전하게 생활할 수 있는 반면에 벽체에 물건을 걸고자 할 때 콘크리트 못을 망치로 쳐서 박거나 걸이구를 접착하여 못이나 걸이구에 걸어야 한다.In general, modern buildings are made of concrete, so that they can be safely lived for a long time. On the other hand, when you want to hang something on the wall, you have to hammer the concrete nail with a hammer or glue the hook and hang it on the nail or the hook.

상기의 못을 콘크리트에 박는 일은 못의 두부를 정확하게 가격하여도 잘 박히지 않는 매우 어려운 작업이고 못의 두부를 정확하게 가격하지 못한 경우에는 못이 멀리 튕겨져서 찾아야 하는 문제점이 잇었다.The nailing of the nail in concrete is a very difficult task that does not hit well even if the head of the nail is accurately priced, and if the head of the nail is not accurately hit, the nail has to be bounced away.

그리고 걸이구를 접착한 후 이에 물건을 거는 경우에는 중량이 가벼운 물건은 그래도 괜찮지만 무거운 중량인 경우에는 오래 지지해주지를 못하고 물건을 떨어트리게 되는 단점이 있었다.And if you hang things on the hanger after attaching the hanger, but the light weight is fine, but the heavy weight had a disadvantage in that the object can not be supported for a long time drop.

그러므로 요즈음에는 콘크리트 못의 두부에 정확하게 타격할 수 있도록 한 타정용 보조기구가 개발되어 제안되고 있는 바, 이는 얼마간 서투른 사람이 망치질을 하여도 타격부를 통하여 콘크리트 못의 두부를 정확하게 가격하면서 콘크리트의 단단한 벽에 잘 박을 수 있도록 하였다.Nowadays, a tableting aid has been developed and proposed to accurately hit the head of the concrete nail. Even if a clumsy person hammers for a while, the hard wall of the concrete can be accurately hit the head of the concrete nail through the hitting part. You can put it on well.

그러나 상기와 같은 종래의 콘크리트 못을 박기 위한 타정용 보조기구에 의하여서는 콘크리트 못을 단단한 벽체에 효과적으로 박을 수 있는 이점이 있는 반면에 콘크리트 못이 벽체이 박히는 힘에 의해 벽체에 금이가거나 콘크리트 조각이 떨어져 나가게 되는 등의 단점이 있었다.However, while the conventional tableting aid for nailing the concrete has the advantage of effectively nailing the concrete nail to a solid wall, the concrete nail cracks the wall or the concrete fragments by the force of the wall. There was a disadvantage such as falling off.

이에 따라 본 발명은 손잡이를 잡고 임팩터를 망치로 치면 케이싱의 내부에서 직선의 왕복운동을 하는 임펙터의 내면에 형성한 나사선에 외면의 나사선이 치합되는 회전척이 드릴을 회전시키는 중에 밀어주어 콘크리트에 작은 직경의 홀을 형성할 수 있도록 함으로써 적은 힘으로 형성한 구멍을 이용하여 콘크리트 못을 쉽게 박을 수 있도록 한 해머 드릴을 제공하는 것을 그 목적으로 한다.Accordingly, the present invention, while holding the handle and hit the impactor with a hammer, the rotary chuck is joined to the screw thread formed on the inner surface of the impactor to make a linear reciprocating motion in the casing of the outer surface is pushed while rotating the drill to the concrete It is an object of the present invention to provide a hammer drill that allows to form a small diameter hole so that concrete nails can be easily driven using a hole formed with a small force.

이와 같은 목적을 달성하기 위한 본 발명은 손잡이가 형성된 본체의 일측에는 원통형의 케이싱을 일체로 형성하고,The present invention for achieving the above object is integrally formed with a cylindrical casing on one side of the handle is formed body,

상기 케이싱의 내부 양측에 형성된 안내홈에 양측의 돌기가 끼워져 상하의 이동만 가능한 임펙터의 중앙에는 나사부와 스프링 홀을 형성하고,The projections on both sides of the guide grooves formed on both sides of the casing are inserted to form a screw portion and a spring hole in the center of the impactor, which can only move up and down,

상기 임펙터의 나사부에 외면에 돌출되게 형성한 나사부가 치합되어 임펙터의 상하이동에 따라 얼마간 회전하는 중에 상하로 이동하는 회전척의 상단에는 스프링 홀을 형성하여 내부에 끼워지는 스프링의 미는 힘을 받도록 하고,The screw part formed to protrude on the outer surface of the screw part of the impactor is engaged so that a spring hole is formed at the upper end of the rotating chuck that moves up and down while rotating for some time according to the shangdong of the impactor so as to receive the pushing force of the spring fitted therein. and,

상기 회전척이 회전하면서 하측으로 이동하는 상태에 따라 고정홀에 끼워진 드릴이 벽체에 구멍을 뚫도록 함으로써 임팩터를 망치로 치면 스프링의 탄성을 받으면서 완만한 경사의 나사선에 의해 하측으로 밀리는 중에 회전하는 드릴로 간단하게 콘크리트나 두꺼운 나무에 작은 직경의 홀을 형성하여 못이나 고정구를 쉽게 박을 수 있도록 한 것이다.As the rotary chuck rotates and moves downward, the drill inserted into the fixing hole drills a hole in the wall so that the impactor is hammered and the spring rotates while being pushed downward by a gentle threaded thread while receiving the elasticity of the spring. By simply forming small diameter holes in concrete or thick wood, it is easy to nail nails or fixtures.
