Description

톱날의 높이조절이 가능한 수동 쇠톱{Height adjustable manual iron saw}Manual hacksaw which can adjust height of saw blade {Height adjustable manual iron saw}

본 발명은 주로 금속재를 수동으로 절단하는데 사용하는 수동 쇠톱에 관한 것이다.The present invention mainly relates to a manual hacksaw used for manually cutting a metal material.

더욱 상세하게는, 톱날의 높이조절을 가능하게 하여 폭이 큰 물체나 좁은 공간에서의 절단작업이 용이하도록 한 톱날의 높이조절이 가능한 수동 쇠톱에 관한 것이다.More specifically, the present invention relates to a manual hacksaw capable of adjusting the height of a saw blade to enable height adjustment of a saw blade to facilitate cutting in a wide object or a narrow space.

종래 각종 산업현장에서 사용하고 있는 수동 쇠톱은 도 1에서 보는 바와 같이 손잡이(11)와 고정부(12)가 형성된 톱대(10)와, 상기 톱대로 부터 길이 방향으로 삽탈되어 위치조절이 가능한 가동대(20)와, 상기 고정부에 회전이 방지되게 삽입되어 그 일측의 나비너트(40)에 의해 길이조절이 가능한 톱날 가이드(30) 및, 상기 가동대와 톱날 가이드의 고정핀(21,31)에 끼워진채 나비너트의 체결력에 의해 적당한 장력을 갖고 설치되는 톱날(50)로 구성되었던 것이다.The manual hacksaw conventionally used in various industrial sites has a saw stand 10 having a handle 11 and a fixing part 12 formed thereon as shown in FIG. (20), the saw blade guide 30 is inserted into the fixing portion to prevent rotation and the length can be adjusted by the butterfly nut 40 on one side, and the fixing pins 21 and 31 of the movable table and the saw blade guide. It was composed of the saw blade 50 is installed with a suitable tension by the fastening force of the butterfly nut while being inserted in.

이러한 수동 쇠톱은 작업자가 톱날(50)의 길이를 감안하여 톱대(10)로 부터 가동대(20)를 적당한 길이만큼 탈거시킨 상태에서 가동대(20)와 톱날 가이드(30)의 고정핀(21,31)에 톱날(50)의 양측에 형성된 홀을 끼우고, 나비너트(40)를 손으로 회전시키면 상기 나비너트의 체결력에 의해 톱날 가이드(30)가 톱날(50)을 외측으로 잡아당기므로써 톱날이 적당한 장력을 갖고 설치되었던 것이다.The manual hacksaw is fixed to the movable pin 20 and the saw blade guide 30 in a state in which the operator removes the movable table 20 from the saw stand 10 by an appropriate length in view of the length of the saw blade 50. Insert the holes formed on both sides of the saw blade 50 to the 31, and rotates the butterfly nut 40 by hand, the saw blade guide 30 pulls the saw blade 50 to the outside by the clamping force of the butterfly nut The saw blade was installed with moderate tension.

그런데, 이와 같은 쇠톱은 가동대(20)가 톱대(10)로 부터 길이 방향으로 삽탈되고, 고정부(12)는 톱대(10)에 일체로 형성되어 있으므로 고정핀(21,31)의 위치를 수평으로는 조절할수 있으나, 높이(수직방향)조절은 불가능한 단점이 있었다.However, in such a hacksaw, since the movable table 20 is inserted in the longitudinal direction from the saw table 10 and the fixing part 12 is integrally formed on the saw table 10, the positions of the fixing pins 21 and 31 are adjusted. It can be adjusted horizontally, but the height (vertical direction) was impossible to adjust.

이로 인해, 절단하고자 하는 물체의 폭이 넓거나 좁은 공간에서 절단작업을 수행할 경우에는 작업 자체가 어렵거나 불가능한 문제점이 있었다.For this reason, when the cutting operation is performed in a wide or narrow space of the object to be cut, the operation itself is difficult or impossible problem.

본 발명은 이러한 문제점을 해결하기 위한 것으로 그 기술적인 과제는 수동 쇠톱의 톱날 높이를 절단조건에 맞게 조절할수 있도록 함에 있다.The present invention is to solve this problem, the technical problem is to be able to adjust the saw blade height of the manual hacksaw according to the cutting conditions.

따라서, 작업자는 상기와 같은 동작으로 톱날의 높이를 조절하여 작업조건에 구애받지 않고 절단작업을 용이하게 실시할수 있다.Therefore, the operator can easily perform the cutting operation regardless of the working conditions by adjusting the height of the saw blade in the above operation.

이하에서 본 발명을 첨부된 도면에 의거 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 2와 도 3은 본 발명에 따른 수동 쇠톱의 실시예를 나타낸 정면도이다.2 and 3 are front views showing an embodiment of a manual hacksaw according to the present invention.

도시한 바와 같이 본 발명은 손잡이(11)와 고정부(12)를 구비하는 톱대(10)와, 상기 톱대의 선단부에 설치되어 길이 방향으로 삽탈되며 고정핀(21)을 구비하는 가동대(20)와, 상기 고정부에 회전이 방지되게 삽입되며 장력조절 수단인 나비너트(40)를 구비하는 톱날 가이드(30) 및, 상기 가동대와 톱날 가이드에 연결되며 나비너트의 체결력에 의해 적당한 장력을 갖고 설치되는 톱날(50)로 구성되는 수동 톱대에 있어서,As shown, the present invention includes a saw stand 10 having a handle 11 and a fixing part 12, and a movable stand 20 provided at a distal end of the saw stand and inserted in the longitudinal direction and having a fixing pin 21 therein. And a saw blade guide 30 which is inserted to prevent rotation of the fixed portion and has a butterfly nut 40 as a tension adjusting means, and is connected to the movable table and the saw blade guide and has a proper tension by a fastening force of the butterfly nut. In the manual saw stand composed of the saw blade 50 is installed with,

상기 톱날 가이드(30)의 선단에 톱날(50)의 홀이 끼워질수 있도록 상하에 고정핀(61)이 형성된 가이드바(60)를 높이 조절이 가능하게 삽입하고, 톱날 가이드(30)의 외측에는 상기 가이드바를 고정시킬수 있는 스크류(70)를 나사 결합하여서 된 것이다.Insert the guide bar 60, the fixing pin 61 is formed in the upper and lower sides so that the hole of the saw blade 50 can be fitted to the tip of the saw blade guide 30 so that the height can be adjusted, the outer side of the saw blade guide 30 By screwing a screw 70 that can fix the guide bar.

가이드바(60)는 톱날 가이드(30)의 선단에 수직하게 삽입되어 원하는 높이로 조절할수 있으며, 그 상하단에는 톱날(50)의 홀이 끼워질수 있는 고정핀(61)이 형성된다.Guide bar 60 is inserted vertically to the tip of the saw blade guide 30 can be adjusted to the desired height, the upper and lower end is formed with a fixing pin 61 that can be fitted into the hole of the saw blade (50).

스크류(70)는 톱날 가이드(30)의 외측에 나사 결합되어 상기 가이드바(60)와 접촉하므로써 가이드바의 높이조절이 완료된 상태에서 제자리에 고정시켜 주는 역할을 하게된다.The screw 70 is screwed to the outside of the saw blade guide 30 is in contact with the guide bar 60 serves to secure in place in the state of height adjustment of the guide bar is completed.

상기와 같이 구성된 본 발명의 작용에 대하여 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

먼저, 절단할 물체의 작업조건에 따라 톱날(50)의 높이를 올린 것인지 내릴 것인지를 결정한다.First, it is determined whether the height of the saw blade 50 is raised or lowered according to the working conditions of the object to be cut.

톱날(50)의 높이를 내릴 경우에는 도 2와 같이 가이드바(60)를 하강시켜 스크류(70)로 고정시킨 다음 하측의 고정핀(61)과 가동대(20)의 고정핀(21)에 톱날(50)의 홀을 끼운다.When lowering the height of the saw blade 50 as shown in Figure 2 by lowering the guide bar 60 and fixed with a screw 70 and then to the fixing pin 61 of the lower side and the fixing pin 21 of the movable table 20 Insert the hole of the saw blade (50).

이후, 나비너트(40)를 체결하여 톱날이 적당한 장력을 갖도록 한다.Thereafter, the butterfly nut 40 is fastened so that the saw blade has a proper tension.

반대, 톱날의 높이를 올릴 경우에는 도 3과 같이 가이드바(60)를 상승시켜 스크류(70)로 고정시킨 다음 상측의 고정핀(61)과 가동대(20)의 고정핀(21)에 톱날(50)의 홀을 삽입한다.On the contrary, in the case of raising the height of the saw blade, the guide bar 60 is raised as shown in FIG. Insert the hole in (50).

이후, 상기와 같이 나비너트를 체결하여 톱날이 적당한 장력을 갖도록 하면 된다.Thereafter, as described above, the butterfly nut may be fastened so that the saw blade has a proper tension.

이상에서 설명한 바와 같이 본 발명의 수동 쇠톱은 톱날 가이드의 선단에 높이 조절이 가능하며 톱날의 홀이 끼워질수 있는 가이드바를 삽입하여 스크류로 고정시키므로써 작업조건에 따라 톱날의 높이를 조절할수 있다.As described above, the manual hacksaw of the present invention can adjust the height of the saw blade guide by inserting a guide bar into which the hole of the saw blade can be inserted and fixing it with a screw.

따라서, 절단 물체의 폭이 넓거나 좁은 공간에서도 톱날의 높이를 조절하여 효과적으로 절단작업을 수행할수 있다.Therefore, the cutting work can be effectively performed by adjusting the height of the saw blade even in a wide or narrow space of the cutting object.
