Abstract

본 고안은 마이크로 스위치의 버튼부과 당김 레버 사이에 걸림부가 구비된 안전부재를 삽입하여, 외부의 충격에 의해 당김 레버가 당겨지더라도 안전부재의 걸림부에 의해 마이크로 스위치의 버튼부가 접촉되지 않아 토치가 작동되지 않게 한 것이다. 상기와 같은 구성으로 이루어져 있기 때문에 사용자가 모르는 사이에 당김 레버에 당겨져 이에 연결된 마이크로 스위치가 눌려져 토치의 오작동으로 인하여 안전사고를 줄일 수 있다.The present invention inserts a safety member with a locking portion between the button portion of the micro switch and the pulling lever, so that even if the pulling lever is pulled by an external impact, the button portion of the micro switch does not come into contact with the locking portion of the safety member. It did not work. Since the configuration is configured as described above, the micro switch connected to it by being pulled on the pull lever without being known by the user is pressed, thereby reducing safety accidents due to malfunction of the torch.

안전장치가 구비된 가스 용접기의 구조. {The structure of carbon welding machine equipped with safely devices.}Structure of gas welder with safety device. {The structure of carbon welding machine equipped with safely devices.}

본 고안은 가스 용접기에 관한 것으로 더욱더 상세하게는 가스 용접기의 안전 장치의 구조에 관한 것이다.
The present invention relates to a gas welder and more particularly to a structure of a safety device of a gas welder.

본 고안은 가스 용접 토치에 관한 것으로 종래의 토치 구조는 관 형상으로 이루어지는 토치 본체에 후단에 연이어 설치되는 핸들, 그리고 핸들의 후단에 피더를 이용해 공급되는 용접 선재를 유도 안내하는 케이블이 연결되는 자동 또는 수동식 용접기의 토치가 있으며, 보통 사용시에는 당김 레버를 당기면 이에 바로 접한 마이크로 스위치의 버튼 부가 눌러져 전기적으로 통전되어 토치 내부로 관통된 용접 와이어의 아크 방전으로 용접을 하는 것으로 당김 레버의 조정으로 편리하게 용접을 할 수 있는 것이다.
The present invention relates to a gas welding torch, and a conventional torch structure has a tubular shape of a torch body connected to a rear end of a handle, and a rear end of the handle is connected to a cable for guiding and guiding a welding wire supplied through a feeder. There is a torch of manual welding machine, and in normal use, when the pull lever is pulled, the button part of the micro switch directly contacted is pressed and it is electrically energized and welded by the arc discharge of the welding wire penetrated into the torch. You can do it.

이산화탄소 용접시에는 토치의 마이크로 스위치가 필수적으로 필요 하나 보통 마이크로 스위치에 바로 접한 당김 레버가 노출되어 사용함으로써, 이동시나, 보관시 사용자가 모르는 사이에 당김 레버가 당겨져 안전사고가 나게 되는 문제점이 생기게 된다.
Torch microswitches are essential for CO2 welding, but the pull lever directly in contact with the micro switch is exposed and used, which causes a problem of safety accidents due to the pulling lever being pulled without the user's knowledge when moving or storing. .

상기와 같은 문제점을 해결하기 위하여 본 고안은 마이크로 스위치의 버튼부과 당김 레버 사이에 걸림부가 구비된 안전부재를 삽입하여, 외부의 충격에 의해 당김 레버가 당겨지더라도 안전부재의 걸림부에 의해 마이크로 스위치의 버튼부가 접촉되지 않아 토치가 작동되지 않게 한 것이다.
In order to solve the above problems, the present invention inserts a safety member provided with a locking portion between the button portion and the pulling lever of the micro switch, and even if the pulling lever is pulled by an external impact, the micro switch is caught by the safety member. The torch does not work because the button part of is not touched.

본 고안은 상기와 같은 구성으로 이루어져 있기 때문에 사용자가 모르는 사이에 당김 레버에 당겨져 이에 연결된 마이크로 스위치가 눌려져 토치의 오작동으로 인하여 안전사고를 줄 일 수 있다.
The present invention is composed of the configuration as described above because the user is not aware of the micro switch is pulled on the pull lever connected to it can reduce the safety accident due to the malfunction of the torch.

본 고안의 핵심인 안전부재(10)의 구성은 손잡이(11)가 형성된 축부(12) 외경에 스프링(13)이 삽입된 후 축부(12) 말단이 걸림부(13)에 형성된 관통공(13-1)에 삽입되어 관통되며, 축부(12) 말단에 구비된 통공(12-1)과 걸림부(13)에 형성된 통공(13-2)으로 고정핀(14)이 삽입되어 고정됨으로 손잡이(11)와 축부(12) 및 걸림부(13)는 일체가 되어 안전부재(10)를 이루어지며, 이를 장착시에는 커버(40) 좌측부에 형성된 제 1 삽입부(40-1)에 상기한 손잡이(11)가 외부에 노출 되도록 삽입하고, 걸림부(13)의 관통공(13-1)에 관통된 축부(12)의 말단은 제 2 삽입부(40-2)에 삽입되고, 이때 스프링(15)의 핀(15-1)는 제 1 삽입부(40-1) 주면에 접촉하게 되며, 반대 측 핀(15-2)은 걸림부(13)를 접하게 되므로 스프링(15)의 탄성에 의해 안전부재(10)는 커버(40)에 지지가 된다.
The construction of the safety member 10, which is the core of the present invention, has a through hole 13 formed at the end of the shaft portion 12 by the spring 13 is inserted into the outer diameter of the shaft portion 12 on which the handle 11 is formed. -1) is inserted into the through hole, the fixing pin 14 is inserted into the through hole (12-2) formed in the through hole (12-1) and the engaging portion 13 provided at the end of the shaft portion (12) and the handle ( 11) and the shaft portion 12 and the engaging portion 13 is formed integrally to form a safety member 10, when mounting the handle described above in the first insertion portion 40-1 formed on the left side of the cover 40 (11) is inserted so as to be exposed to the outside, the end of the shaft portion 12 penetrated through the through hole (13-1) of the locking portion 13 is inserted into the second insertion portion (40-2), where the spring ( The pin 15-1 of 15 is in contact with the main surface of the first inserting portion 40-1, and the opposite pin 15-2 is in contact with the catching portion 13, so that the spring 15 is elastic. The safety member 10 is supported by the cover 40.

상기와 같은 구성으로 이루어진 안전부재(10)를 사용시에는 손잡이(11)를 시계 반대방향으로 90도 조절하게 되면, 손잡이(11)와 축부(12)에 연결된 걸림부(13)가 손잡이(11)와 같이 시계반대 방향으로 90도 회전하여, 당김 레버(60)가 마이크로 스위치(20)의 버튼부(20-1)를 누르는데 아무런 방해가 되지않아 가스용접기(100)를 사용할 수 있으며, 손잡이(11) 축부(12)의 외경에 설치된 스프링(15)의 탄성으로 사용자가 손잡이(11)를 조절하기 전까지 안전부재(10)는 유동 되지 않는다.When using the safety member 10 configured as described above when the handle 11 is adjusted 90 degrees counterclockwise, the handle 11 and the engaging portion 13 connected to the shaft portion 12 is the handle 11 Rotate 90 degrees counterclockwise as shown, the pull lever 60 does not interfere with pressing the button portion 20-1 of the micro switch 20 can use the gas welder 100, the handle ( 11) The safety member 10 does not flow until the user adjusts the handle 11 by the elasticity of the spring 15 installed on the outer diameter of the shaft portion 12.

상기한 손잡이(11)를 시계방향으로 90도 조절하게 되면, 손잡이(11)와 축부(12)에 연결된 걸림부(13)가 손잡이(11)와 같이 시계방향으로 90도 회전함으로써, 부주의에 의해 당김 레버(60)가 눌러 지더라도 걸림부(13)에 의해 마이크로 스위치(20)의 버튼부(20-1)를 누르지 못하게 되므로 이동시나, 보관시 사용자가 안전하게 사용할 수가 있다.
When the knob 11 is adjusted 90 degrees in the clockwise direction, the locking portion 13 connected to the handle 11 and the shaft portion 12 rotates 90 degrees clockwise like the handle 11, thereby inadvertently Even when the pull lever 60 is pressed, the button portion 20-1 of the micro switch 20 cannot be pressed by the locking portion 13, so that the user can safely use it when moving or storing.
