산소절단기의 연료공급용 호스 연결구조{Hose connection structure for fuel supply of oxygen cutting machine}Hose connection structure for fuel supply of oxygen cutting machine

본 발명은 산소절단기의 연료공급용 호스 연결구조에 관한 것으로, 더욱 상세하게는 피복처리된 플렉시블금속관이나 내부에 금속망이 씌워진 플렉시블호스로 제작되고 내부에 가스튜브와 산소튜브를 연결설치하여 만들어진 외줄연결호스를 분기접속구를 이용하여 토오치와 연결설치하되,The present invention relates to a hose connection structure for fuel supply of an oxygen cutter, and more particularly, an outer line made of a coated flexible metal tube or a flexible hose covered with a metal mesh inside, and connecting a gas tube and an oxygen tube inside. Connect and install the connecting hose with the torch using the branch port,

토오치를 연결하기 위한 토오치연결부분을 특수하게 구성하여서, 제작사 마다 토오치 체결구의 상하, 전후 체결 간격이 다르게 형성되어 있어서 분기접속구와 토오치를 연결하기 위해 가스호스와 산소호스를 약 50㎝ 길이로 길게 연결하여야 하는 기존의 방법이 아니라, 약 50㎝ 길이로 길게 연결되던 가스호스와 산소호스를 사용하지 않아도 되도록 하여 제작비용이 절감되면서도, 토오치의 체결이 매우 용이하도록 함은 물론 토오치와 분기접속구와의 거리를 최대한 짧게하여 토오치의 사용이 용이하고, 종래와 같이 가스호스와 산소호스의 훼손으로 인한 안전사고의 위험을 완벽하게 제거하여 안심하고 작업에 임할 수 있도록 한 산소절단기의 연료공급용 호스 연결구조에 관한 것이다.The torch connection part for connecting the torch is specially configured, and the top and bottom, front and rear fastening intervals of the torch fastener are different for each manufacturer. It is not the existing method that requires a long connection in length, but eliminates the need to use a gas hose and an oxygen hose that were connected at a length of about 50 cm, thereby reducing manufacturing costs and making it very easy to fasten the torch The oxygen cutting machine is designed to make it easier to use the torch by shortening the distance between the junction and the branch connector, and to completely eliminate the risk of safety accidents caused by damage to the gas and oxygen hoses as in the past, so that you can work with confidence. It relates to a hose connection structure for fuel supply.

일반적으로 산소절단기는 산소나 아세틸렌 또는 액화천연가스(LPG) 등의 연료가스가 연소 할 때 발생되는 연소열로 피공작물을 녹여 상호 융착시키거나, 피공작물의 용융된 부위를 고압으로 분사되는 산소로 불어내어 피공작물을 절단하는 장치로서, 연료가스탱크 및 산소탱크과 각각 이들과 연결되어진 연료공급호스 및 산소공급호스의 타측단에 연결되어 연료가스 및 산소를 공급받는 토오치로 구성된다.In general, oxygen cutters use the combustion heat generated when fuel gas such as oxygen, acetylene, or liquefied natural gas (LPG) is combusted to melt and fuse the workpiece, or blow the molten part of the workpiece with oxygen injected at high pressure. This is a device for cutting a workpiece, and it is composed of a fuel gas tank and an oxygen tank, and a torch connected to the other end of the fuel supply hose and the oxygen supply hose respectively connected thereto to receive fuel gas and oxygen.

그런데 종래의 산소절단기는 대부분 첨부도면 도 1에 도시된 바와 같이 연료가스탱크(1)에는 연료가스를 공급하는 가스호스(41)가 연결되어 있고 산소탱크(2)에는 산소를 공급하는 산소호스(42)가 각각 연결설치되어 있으며 이들 가스호스(41)와 산소호스(42)는 모두 토오치(3)에 연결설치되어 있다.However, in most conventional oxygen cutters, as shown in the accompanying drawings, a gas hose 41 for supplying fuel gas is connected to the fuel gas tank 1, and an oxygen hose for supplying oxygen to the oxygen tank 2 ( 42 are connected to each other, and these gas hoses 41 and oxygen hoses 42 are all connected to the torch 3 .

그러나, 이렇게 가스호스(41) 및 산소호스(42)를 두 줄로 길게 연결하여 사용하는 경우에는 산소절단 작업과 용접작업 수행시 각각의 가스호스(41) 및 산소호스(42)가 서로 뒤엉켜서 산소절단작업을 진행할 때에도 상당한 불편함이 발생되고, 절단작업 후에 각각의 가스호스(41) 및 산소호스(42)를 정리하는 것에도 상당한 불편함이 뒤따랐다.However, when the gas hose 41 and the oxygen hose 42 are connected in two long lines in this way, each gas hose 41 and the oxygen hose 42 are entangled with each other during the oxygen cutting operation and the welding operation. Significant inconvenience is generated even when the cutting operation is performed, and considerable inconvenience is also followed in arranging each gas hose 41 and oxygen hose 42 after the cutting operation.

이에 이와같은 문제점을 해결하기 위해서 타인의 선등록 발명인 특허등록 제10-0865154호인 첨부도면 도 2 내지 도 3에서 보는 바와 같이 분기접속구(10)를 이용하여 피복(30b)된 플렉시블금속관(30a)으로 만들어진 외줄연결호스(30)의 내부에 가스튜브(31)와 산소튜브(32)를 삽입하여서 단일 구조의 외줄로 된 연료공급용 호스를 구성하거나,Accordingly, in order to solve this problem, as shown in the attached drawings 2 to 3, which is a patent registration No. 10-0865154, which is a previously registered invention of another person, a flexible metal tube 30a coated with a branch connection port 10 is used as a flexible metal tube 30a. By inserting the gas tube 31 and the oxygen tube 32 into the made outer line connection hose 30, a single structure of the outer line hose for fuel supply is constructed, or

본인의 선등록 발명인 특허등록 제 10-164006호인 첨부도면 도 4 내지 도 6에서 보는 바와 같이 가스누출확인공(100b)이 구비되는 분기접속구(100)를 이용하여 피복(200b)처리된 플렉시블금속관(200a)이나 내부에 금속망이 씌워진 플렉시블호스 등으로 제작된 외줄연결호스(200)의 내부에 가스튜브(201)와 산소튜브(202)를 연결설치하여 만들어진 산소절단기의 연료공급용 호스를 제공하여 이를 이용하여 결과적으로 산소탱크(2) 및 가스탱크(1)를 토오치(3)와 연결이 용이하고 용접이나 절단작업시 선의 꼬임이나 엉킴 현상이 전혀 발생하지 않고, 불똥이나 절단된 쇠조각, 쓰다버린 용접봉, 날카로운 절단면이나 모서리 등에 의해 상기 외줄연결호스(200)가 훼손될 염려가 없는 것은 물론 사용 전은 물론이고,As shown in the attached drawings 4 to 6 of the patent registration No. 10-164006, which is a previously registered inventor of the person, the flexible metal pipe (200b) treated using the branch connection port 100 provided with the gas leak check hole 100b ( 200a) or by connecting the gas tube 201 and the oxygen tube 202 to the inside of the outer line connection hose 200 made of a flexible hose covered with a metal mesh, etc. As a result, it is easy to connect the oxygen tank (2) and the gas tank (1) with the torch (3), and there is no twisting or tangling of wires during welding or cutting, sparks or cut pieces of iron, There is no fear of damage to the outer-line connection hose 200 by a spent welding rod, a sharp cut surface or edge, of course, before use as well as,

사용도중이나 사용 후 언제라도 가스누출여부와 가스누출부위의 식별이 용이하여 안전사고의 발생이 없도록 하여 주며, 가스누출부위의 신속한 수리로 유지보수 또한 용이하여 누구나 안심하고 용접이나 절단작업에 임할 수 있도록 하였다.During or after use, it is easy to identify gas leaks and gas leaks, so there is no safety accident. made to be

그런데, 위와 같은 타인의 선등록 발명 및 본인의 선등록 발명에서 개시된 단일 구조의 외줄로 된 산소절단기의 연료공급용 호스는,By the way, the hose for fuel supply of the single-line, single-line oxygen cutter disclosed in someone else's pre-registered invention and my own pre-registered invention as described above,

대부분 제작사 마다 토오치 체결구의 상하, 전후 체결 간격이 다르게 형성되어 있는 것이 많아서 각각 분기접속구(10)(100)와 토오치(3)를 연결하기 위해 가스호스(41)(210)와 산소호스(42)(220)를 약 50㎝ 길이로 길게 연결하여야 하는 방법을 채택하고 있는바, 이와 같은 방법은 가스호스(41)(210)와 산소호스(42)(220)의 길이가 약 50㎝로 비교적 길기 때문에 불필요하게 제작비용이 많이 소요되고,In most manufacturers, the upper and lower, front and rear fastening intervals of the torch fasteners are formed differently, so gas hoses 41, 210 and oxygen hoses ( 42) A method in which the 220 is connected to a length of about 50 cm is adopted. In this method, the length of the gas hoses 41 and 210 and the oxygen hoses 42 and 220 is about 50 cm. Because it is relatively long, the production cost is unnecessarily high,

연결길이가 길어진 만큼 외부로 노출되는 부위가 많아서,As the length of the connection is longer, there are many parts exposed to the outside,

여전히 용접이나 절단작업시 선의 꼬임이나 엉킴 현상이 종종 발생하였으며, 무엇보다도 불똥이나 절단된 쇠조각, 쓰다버린 용접봉, 날카로운 절단면이나 모서리 등에 의해 가스호스(41)(210)와 산소호스(42)(220)가 훼손될 염려가 완벽하게 해결되지 않았다.Still, twisting or tangle of wires occurred during welding or cutting work, and above all, gas hoses 41 (210) and oxygen hoses (42) ( 220) was not completely resolved.

본 발명은 상기와 같은 종래의 제반 문제점을 감안하여 안출한 것으로, 토오치를 연결하기 위한 토오치연결구조를 특수하게 구성하여서, 제작사 마다 체결구의 상하, 전후 체결 간격이 제작사마다 다르게 형성되어 있어서 분기접속구와 토오치를 연결하기 위해 가스호스나 산소호스를 약 50㎝ 길이로 길게 연결하여야 하는 기존의 방법이 아니라,The present invention was devised in view of the various problems of the prior art, and by specially configuring the torch connection structure for connecting the torch, the upper and lower, front and rear fastening intervals of the fasteners for each manufacturer are formed differently for each manufacturer. It is not the existing method of connecting a gas hose or an oxygen hose with a length of about 50 cm to connect the connection port and the torch.

산소튜브는 분기접속구에 후단이 일체형으로 용접설치되는 동파이프로 된 산소부싱과 산소니플 및 산소너트 등의 금속 또는 비철금속으로된 연결부재를 이용하여 토오치의 산소체결구에 체결하고,The oxygen tube is fastened to the oxygen connector of the torch by using an oxygen bushing made of copper pipe, which is integrally welded to the rear end of the branch connector, and a connecting member made of metal or non-ferrous metal such as oxygen nipple and oxygen nut,

상기 가스튜브는 SUS플렉시블호스를 토오치 체결구의 상하, 전후 체결 간격에 맞추어 적절히 절곡시켜가면서 가스부싱 그리고 가스니플 및 가스너트 등의 연결부재를 이용하여 토오치 가스체결구에 체결하도록 함으로써,In the gas tube, the SUS flexible hose is properly bent according to the upper and lower, front and rear fastening intervals of the torch fastener, and fastened to the torch gas fastener using a gas bushing and connecting members such as a gas nipple and a gas nut.

종래방식과 같이 약 50㎝ 길이로 길게 연결되던 가스호스와 산소호스를 전혀 사용하지 않아도 되도록 하여 제작비용이 절감되면서도, 토오치의 체결이 매우 용이하도록 함은 물론 토오치와 분기접속구와의 거리를 최대한 짧게 하여 토오치의 사용이 용이하고, 종래와 같이 가스호스와 산소호스의 훼손으로 인한 안전사고의 위험을 완벽하게 제거하여 안전사고의 발생없이 안심하고 작업에 임할 수 있도록 하여 주고자 함에 그 목적을 둔 것이다.다.As in the conventional method, it is not necessary to use a gas hose and an oxygen hose, which were long connected at about 50 cm in length, thereby reducing manufacturing costs, making it very easy to fasten the torch and reducing the distance between the torch and the branch connector. The purpose of the torch is to make it as short as possible and to make it easier to use the torch and to completely eliminate the risk of safety accidents due to damage to the gas and oxygen hoses as in the past, so that you can work safely without any safety accidents. will have

상기 해결하고자 하는 과제에 기재된 목적을 달성하기 위한 본 발명의 산소절단기의 연료공급용 호스 연결구조는 기본적으로 피복처리된 플렉시블금속관이나 내부에 금속망이 씌워진 플렉시블호스로 제작되고 내부에 가스튜브와 산소튜브를 연결설치하여 만들어진 외줄연결호스를 분기접속구를 이용하여 토오치와 연결설치하되,The hose connection structure for fuel supply of the oxygen cutter of the present invention for achieving the object described in the above-mentioned problem to be solved is basically made of a coated flexible metal tube or a flexible hose with a metal mesh inside, and a gas tube and oxygen inside Connect and install the outer line connection hose made by connecting the tube to the torch using the branch connection port,

상기 분기접속구를 각각 통과하여 토오치와 연결되는 가스튜브 및 산소튜브는,A gas tube and an oxygen tube connected to the torch through the branch connection port, respectively,

산소튜브의 경우에는 분기접속구에 후단이 일체형으로 연계설치되는 금속 또는 비철금속으로된 연결부재를 이용하여 토오치의 산소체결구에 체결하고,In the case of oxygen tube, it is fastened to the oxygen fastener of the torch using a connecting member made of metal or non-ferrous metal that is integrally connected to the rear end of the branch connection port,

여기서, 상기 플렉시블호스(600)는 플렉시블금속관(600) 또는 금속망이 씌워진 플렉시블호스(610)를 사용할 수 있는데 그 이유는 잘 구부러지면서도 용접 불똥이나 불똥이나 절단된 쇠조각 등에 의하여도 훼손이 거의 없기 때문이다.Here, the flexible hose 600 may use a flexible metal pipe 600 or a flexible hose 610 covered with a metal mesh because it is bent well and is almost damaged even by welding sparks, sparks, or cut pieces of iron. because there is no

바람직하게는 피복하지 않은 플렉시블금속관(600)을 사용하는 것이 가장 이상적이다.Preferably, it is most ideal to use an uncoated flexible metal tube (600).

여기서 상기 분기접속구(100)는 본인의 선등록 발명에서 보는 바와 같이 원통형 금속관체를 성형가공하여 제작할 수 도 있으며, 또는 주물로 제작하여 얻어진 것을 사용할 수 도 있다.Here, the branch connector 100 may be manufactured by molding and processing a cylindrical metal tube, as shown in the person's pre-registered invention, or one obtained by manufacturing by casting may be used.

또한 상기 분기접속구(100)에는 가스누출확인공(100b)을 형성할 수도 있는데 이와 같이 하면 가스튜브(201)나 산소튜브(202)의 연결부분이 훼손되거나 헐거워져 가스가 새어나오면 가스누출확인공(100b)을 통해 누출되기때문에 냄새나 소리음으로서 확인할 수 있기 때문에 사용 전 가스가 새는지 여부를 미연에 확인할 수 있다.In addition, a gas leak check hole 100b may be formed in the branch connection port 100. In this way, when the connection part of the gas tube 201 or the oxygen tube 202 is damaged or loosened and gas leaks, the gas leak check hole Because it leaks through (100b), it can be confirmed as a smell or sound, so it is possible to check in advance whether gas is leaking before use.

상기와 같은 본 발명은 상기 플렉시블호스(600) 즉, 플렉시블금속관(601) 또는 금속망이 씌워진 플렉시블호스(602)가 잘 구부려지므로 도 7과 같이 토오치(3) 제작사 마다 산소체결구(3a)와 가스체결구(3b)의 상하, 전후 체결 간격이 다르더라도 토오치(3)의 체결이 매우 용이하다.In the present invention as described above, since the flexible hose 600, that is, the flexible metal tube 601 or the flexible hose 602 covered with a metal mesh, is bent well, as shown in FIG.

그리고 토오치의 사용시 상기 플렉시블호스(600) 즉, 플렉시블금속관(601) 또는 금속망이 씌워진 플렉시블호스(602)은 잘 구부려지지만 분기접속구(100)에 후단이 일체형으로 용접설치되는 동파이프로 된 산소부싱(510)은 절대로 구부러지지 않기때문에 체결상태가 매우 견실한 것은 물론 토오치의 사용시 연결부가 절대로 접히지 않아 사용이 매우 편리하다.And when the torch is used, the flexible hose 600, that is, the flexible metal tube 601 or the flexible hose 602 covered with a metal mesh, is bent well, but the rear end is integrally welded to the branch connection port 100. Oxygen made of a copper pipe Since the bushing 510 is never bent, the fastening state is very strong, and the connection part is never folded when the torch is used, so it is very convenient to use.

또한, 종래방식과 같이 약 50㎝ 길이로 길게 연결되던 가스호스와 산소호스를 사용하지 않아도 되므로 제작비용이 대폭 절감된다.In addition, since it is not necessary to use a gas hose and an oxygen hose that were long connected to a length of about 50 cm as in the conventional method, the manufacturing cost is greatly reduced.

또한, 연결부위가 매우 짧아 노출부위가 적고 그마저도 플렉시블금속관(601) 또는 금속망이 씌워진 플렉시블호스(602)은 내구성이 강하여 종래와 같이 가스호스와 산소호스 사용시 노출되는 부위가 많아서 여전히 용접이나 절단작업시 선의 꼬임이나 엉킴 현상이 발생하는 것이나 또는 불똥이나 절단된 쇠조각, 쓰다버린 용접봉, 날카로운 절단면이나 모서리 등에 의해 가스호스와 산소호스가 훼손되어 안전사고가 발생할 수 있는 등의 염려가 완벽하게 해결된다.In addition, since the connection part is very short, there are few exposed parts, and even that, the flexible metal tube 601 or the flexible hose 602 covered with a metal mesh has strong durability. It completely solves concerns such as kinking or tangle of wires, sparks, cut pieces of iron, spent welding rods, and damage to gas and oxygen hoses due to sharp cut edges or edges, which may cause safety accidents. do.
