Abstract

본 고안은 핸드드릴에 관한 것으로, 좀더 상세하게는 수직 또는 수평방향으로 구멍을 천공할때 작업자 혼자서도 매우 정확하게 천공할수 있게 하기위한 것이다.The present invention relates to a hand drill, and more particularly, to be able to drill very precisely by the operator alone when drilling holes in the vertical or horizontal direction.

주지된 바와같이 핸드드릴은 소형이기에 손에 쥐고 옮겨다니면서 손쉽게 구멍을 천공할수 있는 잇점이 있는 반면에 손잡이부분과 스핀들 동체가 거의 90°의 각을 이루는 권총형상으로 형성되어 있어 수직 또는 수평구멍을 천공할때 작업자의 시야로는 직립및 수평각도를 정확하게 볼수 없는 문제점이 따르게 된다.As is well known, the hand drill is compact and has the advantage of making it easy to drill holes while moving in the hand, while the handle and the spindle body are formed in the shape of a pistol with an angle of almost 90 ° to drill a vertical or horizontal hole. When the worker's field of view is accompanied by a problem that can not see the upright and horizontal angle accurately.

한편, 통상 핸드드릴로 구멍을 천공할때는 못이나 쇄기등을 박기위한 용도이외에 탭을 내어 나사결합이 가능하게 할수 있도록 하는 용도로도 사용되며, 이경우 구멍이 기울어진 상태로 천공되면 탭 역시 기울어진 상태로 형성되며, 따라서 나사결합이 정확하게 이루어질수 없게 된다.On the other hand, when drilling a hole with a hand drill, it is used not only for nailing nails or wedges, but also for making a screw connection possible by tapping the tap.In this case, when the hole is tilted, the tab is also tilted. It is formed to, so that the screw can not be made accurately.

또한 드릴링 또는 탭핑시 구멍자체가 기울어진 상태로 천공되다보면, 드릴이나 탭이 쉽게 파손되기도 한다.In addition, when drilling or tapping, when the hole itself is drilled in an inclined state, the drill or the tap may be easily broken.

이에 본 고안은 핸드드릴로 수직 또는 수평구멍을 뚫더라도 직립도및 수평도를 정확하게 유지할수 있게 하려는데 그 목적이 있으며, 이러한 목적을 효과적으로 달성하기 위해 드릴의 적정위치 즉, 손잡이와 스핀들 동체가 만나는 꼭지점 부분에 물수평장치를 설치하되, 상기 물수평장치의 적정위치(수직 또는 수평확인이 용이한 위치)에 수직또는 수평확인용 표시부를 형성하여, 수직 또는 수평으로 구멍을 천공할때 매우 효율적으로 천공할 수 있게 하려는 것이다.Accordingly, the present invention aims to accurately maintain the straightness and horizontality even when drilling vertical or horizontal holes with a hand drill, and in order to achieve this purpose effectively, the vertex where the handle and the spindle body meet. Water level device is installed on the part, but the vertical or horizontal check display part is formed at the proper position of the water level device (easily vertical or horizontal check), so when drilling the hole vertically or horizontally very efficiently I want to be able to.

Description

핸드 드릴{hand drill}Hand drill

본 고안은 핸드드릴에 관한 것으로, 보다 상세하게는 수직 또는 수평방향으로 구멍을 천공할때 작업자 혼자서라도 매우 신속 정확하게 천공할 수 있게 하기 위한 것이다.The present invention relates to a hand drill, and more particularly, to be able to drill very quickly and accurately even by the operator alone when drilling holes in the vertical or horizontal direction.

주지된 바와같이 핸드드릴은 소형이기에 손에 쥐고 옮겨다니면서 손쉽게 구멍을 천공할수 있는 잇점이 있는 반면에 손잡이 부분과 스핀들 동체가 거의 90°의 각을 이루는 권총형상으로 형성되어 있어, 각종 기계기구류 또는 건축물의 벽체등에 수직 또는 수평구멍을 천공할때 작업자의 시야로 직립및 수평각도를 정확하게 볼수 없는 문제점이 따르게 된다.As is well known, the hand drill is compact and has the advantage of making it easy to drill holes while moving in the hand, while the handle part and the spindle body are formed in the shape of a pistol with an angle of almost 90 °. When drilling a vertical or horizontal hole in the wall, etc. of the worker will not be able to see the upright and horizontal angle accurately by the operator's field of view.

또한, 각종 기계 기구류에 구멍을 천공한 후에는 탭을 내는 경우도 허다한데일단 드릴구멍이 정확하게 천공되지 않으면, 탭 또한 정확하게 작용하지 못하게되어, 정밀도및 조립성이 크게 떨어지고, 또 구멍자체가 기울어진 상태로 천공되기 때문에 구멍가공중 드릴이 부러지는 등의 폐단이 따른다.In addition, after drilling holes in various kinds of machine tools, even if the taps are made in many cases, if the drill holes are not drilled correctly, the tabs also cannot work correctly, which greatly reduces the precision and assemblability, and the hole itself is inclined. Because it is drilled in a state, a closed end such as a drill is broken during drilling is followed.

따라서 숙련된 작업자라 하더라도 구멍가공에 정밀성 및 정확성을 기대하기 어려워 핸드드릴 작업에 따른 정밀도, 정확도등을 기대할수 있는 장치의 개발이 대두되었던 것이다.Therefore, even a skilled worker is difficult to expect the precision and accuracy in the hole processing, the development of a device that can expect the precision, accuracy, etc. according to the hand drill operation has emerged.

본 고안은 전술한 종래의 문제점을 해결하기 위해 안출된 것으로, 특히 통상의 핸드드릴 적정위치 즉, 손잡이와 스핀들 동체가 만나는 꼭지점 부분에 물수평장치를 설치하되, 상기 물 수평장치의 적정위치(즉, 수직또는 수평확인이 용이한 위치)에 수직또는 수평확인이 용이한 표시부를 형성하여, 수직또는 수평으로 구멍을 천공할때 매우 효율적으로 천공할 수 있게 하려는데 그 목적이 있다.The present invention has been made to solve the above-mentioned conventional problems, in particular, the water leveling device is installed at the vertex of the normal hand drill proper position, that is, the handle and the spindle fuselage, the proper position of the water leveling device (ie It is an object of the present invention to form a display unit that is easy to check vertically or horizontally at a position where vertical or horizontal check is easily performed, and to drill a hole very efficiently when drilling a hole vertically or horizontally.

통상의 핸드드릴에 있어서,In a conventional hand drill,

손잡이(1)와 스핀들 동체(2)가 만나는 꼭지점 부분에 물수평장치(3)를 설치하되, 상기 물 수평장치(3)는 투명 캡슐타잎으로 동체(31)를 형성하되, 핸드드릴의동체내에 끼워져 결합되도록 동체(31) 하측 외주면에 결합요부(32)를 형성하여 핸드드릴의 동체를 구성하는 양측 케이스(4)(4')에 끼워져 고정되게 하고, 내부에는 소정량의 물(33)을 충진시킴과 동시에 공기방울(34)이 내장되도록 하며, 상기 물수평장치(3)의 표면 적정위치에 드릴동체에 장착된 상태에서 수직 또는 수평위치를알수 있도록 수직 또는 수평확인용 표시부(35)(35')를 형성하여서 된것이다.Water level device (3) is installed at the vertex of the handle (1) and the spindle body (2), the water level device (3) forms a body (31) with a transparent capsule type, but in the body of the hand drill A coupling recess 32 is formed on the outer circumferential surface of the lower side of the body 31 so as to be fitted and coupled to each other so as to be fitted into and fixed to both cases 4 and 4 'constituting the body of the hand drill. At the same time, the air bubble 34 is filled and the vertical or horizontal check display part 35 is provided so that the vertical or horizontal position can be known while being mounted on the drill body at the proper position of the surface of the water leveling device 3. 35 ').

미설명부호 5는 스핀들이다.Reference numeral 5 is a spindle.

이와같이 구성된 본 고안은 물 수평장치(3)가 핸드드릴에 장착된 상태이기 때문에 핸드드릴로 구멍을 뚫을 때 수평또는 수직의 구멍을 매우 정확하고도 안정적으로 천공할 수 있게 되는 것이다.The present invention configured as described above is able to perforate the horizontal or vertical hole very accurately and stably when the water level device 3 is mounted on the hand drill.

즉, 본 고안에서는 물수평장치(3)를 손잡이(1)와 스핀들동체(2)가 만나는 지점에 고정설치한데다가 상기 물 수평장치(3)에는 수평 또는 수직을 확인할수 있도록 수직 또는 수평확인용 표시부(35)(35')를 형성한 것임으로, 각종기계 기구를 비롯하여 벽면에 구멍을 천공할때 수직 또는 수평확인용 표시부를 바라보면서 천공할수 있게되어 매우 정확하면서도 안정적으로 구멍을 천공할수 있게 되는 것이며, 더불어 구성이 간단하면서도 기능은 뛰어나 신뢰성을 극대화 시킬수 있게 되는것이다.That is, in the present invention, the water leveling device 3 is fixedly installed at the point where the handle 1 and the spindle body 2 meet, and the water leveling device 3 is vertical or horizontal for checking the horizontality or verticality. By forming the display parts 35 and 35 ', it is possible to drill while looking at the vertical or horizontal check display part when drilling holes on the wall including various machine tools, so that the hole can be drilled very accurately and stably. In addition, the configuration is simple, but the function is excellent to maximize the reliability.

이상 설명한 바와같이 본 고안은 통상의 핸드드릴에 물 수평장치를 설치함으로서 각종 기계기구류 및 벽면에 구멍을 천공할때 매우 정확하면서도 간편하게 천공할수 있고, 또 구성이 간편하여 제조원가가 과다하게들 염려가 없음은 물론, 신뢰성을 극대화 시킬수 있는 매우 유용한 고안인 것이다.As described above, the present invention provides a very accurate and simple punch when drilling holes in various machinery and walls by installing a water level device on a conventional hand drill, and there is no fear of excessive manufacturing cost due to its simple configuration. Of course, it is a very useful design that can maximize reliability.
