Technical Solution
[5] To accomplish the above objects, according to the present invention, there is provided a straight type welding torch, which includes a gas injection port and an oxygen injection port disposed on the rear part of a hand grip for injecting gas and oxygen through a connection hose, a gas-adjusting part and an oxygen-adjusting part respectively mounted at both ends of the hand grip for adjusting an injection amount of gas and oxygen, a gas-mixing unit connected to the oxygen-adjusting part for mixing the injected gas and oxygen, a gas mixture tube for passing the mixture of gas and oxygen therethrough, and a fire port for ejecting the mixture of gas and oxygen, wherein the gas-adjusting part includes a gas-adjusting cap, a gas needle valve assembled inside the gas-adjusting cap, the needle value having a gas passageway formed therein so as to fluidically communicate with the gas injection port and an oxygen passageway formed therein so as to fluidically communicate with the oxygen injection port, and a sealing means mounted on the outer periphery of the gas needle valve for hermetically sealing a gas chamber and an oxygen chamber, the gas chamber and the oxygen chamber being formed by engaging the gas needle valve and a gas valve chamber having an oxygen inducing tube with each other, wherein the oxygen- adjusting part includes an oxygen-adjusting cap, an oxygen needle valve assembled inside the oxygen-adjusting cap, the oxygen needle valve having a gas passageway and an oxygen passageway formed therein so as to respectively fluidically communicate with a gas-mixing chamber, and a sealing means mounted on the outer periphery of the oxygen needle valve for hermetically sealing a gas chamber and an oxygen chamber, the gas chamber and the oxygen chamber being formed by engaging the oxygen needle valve and an oxygen valve chamber having a gas inducing tube with each other, and wherein the hand grip includes a gas tube mounted therein for connecting the gas chamber of the gas valve chamber with the gas inducing tube of the oxygen valve chamber, and an oxygen tube mounted therein for connecting the oxygen inducing tube of the gas valve chamber with the oxygen chamber of the oxygen valve chamber, whereby the hand grip, the gas-adjusting part and the oxygen-adjusting part are formed in a straight line.

[6] The straight type welding torch according to the present invention allows even the unskilled person to easily set the mixing ratio of good flame using a scale indicated on the outer periphery of a hand grip thereof, and prevent the user's sleeve from being caught to the gas or oxygen-adjusting part during welding. Brief Description of the Drawings
[7] FlG. 1 is a view illustrating a prior art welding torch.
[8] FlG. 2 is a perspective view of the present invention.
[9] FlG. 3 is a sectional view of essential parts of the present invention.
[10] FIGS. 4 and 5 are detailed views of "A" and "B" parts of HG. 3.
Mode for the Invention
[11] Reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings.
[12] FlG. 2 is a perspective view of the present invention, FlG. 3 is a sectional view of essential parts of the present invention, and FIGS. 4 and 5 are detailed views of "A" and "B" parts of FlG. 3. As shown in FIGS. 2 and 3, a gas-adjusting part 10 and an oxygen-adjusting part 30 are mounted at both ends of a hand grip 20, in which a gas tube 21 and an oxygen tube 22 are embedded.
[13] As shown in FlG. 3, the gas-adjusting part 10 mounted on the rear part of the hand grip 20 includes a gas needle valve 12 assembled inside a gas-adjusting cap 11 and the gas needle valve 12 includes a gas passageway 12a fluidically communicating with a gas injection port 52 and an oxygen passageway 12b fluidically communicating with an oxygen injection port 53.
[14] Moreover, the gas needle valve 12 has a projected form, and rubber rings 17 are mounted on the outer peripheries of the projected portions and the center of the gas needle valve 12.
[15] The rubber rings 17 of the gas needle valve 12 are provided to seal a gas chamber
14 and an oxygen chamber 15 inside a gas valve chamber 13, wherein the gas chamber 14 and the oxygen chamber 15 are formed by engaging the gas needle valve 12 and the gas valve chamber 13 with each other. Instead of the rubber rings 17, Teflon may be coated on the entire outer periphery of the gas needle valve 12. An oxygen inducing tube 16 is formed inside the gas valve chamber 13 to induce oxygen contained inside the oxygen chamber 15 to the oxygen tube 22.
[16] The gas-adjusting part 10 adjusts an amount of injected gas when the gas-adjusting cap 11 is turned, and in this instance, pressure and inflow of gas introduced into the gas chamber 14 through the gas injection port 52 and the gas passageway 12a are determined according to a volume change of the gas chamber 14 determined by the position of the projected portion of the gas needle valve 12 interlocking with the gas- adjusting cap 11.
[17] Furthermore, in FlG. 4, a flow path of gas and oxygen flowing from the gas- adjusting part 10 is indicated by an arrow. Referring to FlG. 4, interception of gas supply from the gas-adjusting part 10 will be described as follows. When the gas- adjusting cap 11 is turned, the projected portion (two-dotted line portion indicated inside the gas chamber 14) of the gas needle valve 12 is in contact with the tube wall, so that gas introduced into the gas tube 21 is intercepted. However, without regard to the interception of gas, at the two-dotted line portion indicated inside the oxygen chamber 15, an entrance of the oxygen tube 22 is not completely closed inside the oxygen chamber 15 fluidically communicating with the oxygen tube 22, so that oxygen can be continuously introduced along the oxygen tube 22. The reason is that the gas- adjusting part 10 controls only interception and inflow of gas and the oxygen-adjusting part 30, which will be described later, controls interception and inflow of oxygen.
[18] The fundamental structure of the oxygen-adjusting part 30 mounted at the front part of the hand grip 20 is the same as the gas-adjusting part 10. However, differently from the gas-adjusting part 10 in which the oxygen tube 22 and the gas tube 21 respectively fluidically communicate with the oxygen injection port 53 and the gas injection port 52, in the oxygen-adjusting part 30, the oxygen tube 22 and the gas tube 21 are all connected to a gas-mixing unit 40 and a gas-mixing chamber 41.
[19] The adjustment of the oxygen amount of the oxygen-adjusting part 30 is made in the same way as the adjustment of the gas amount of the gas-adjusting part 10. That is, the injected oxygen amount is adjusted by turning an oxygen-adjusting cap 31. In this instance, pressure and inflow of oxygen introduced into the oxygen chamber 35 through the oxygen tube 22 inside the hand grip 20 are determined according to a volume change of the oxygen chamber 35 determined by the position of the projected portion of an oxygen needle valve 32 interlocking with the oxygen-adjusting cap 31.
[20] In addition, in FlG. 5, a flow path of gas and oxygen flowing from the oxygen- adjusting part 30 is indicated by an arrow. Referring to FlG. 5, interception of oxygen supply from the oxygen-adjusting part 30 will be described as follows. When the oxygen-adjusting cap 31 is turned, the projected portion (two-dotted line portion indicated inside the oxygen chamber 35) of the oxygen needle valve 32 is in contact with the tube wall, so that oxygen introduced into the oxygen tube 22 is intercepted. However, without regard to the interception of oxygen, at the two-dotted line port indicated inside the gas chamber 34, an entrance of the gas tube 21 is not completely closed inside the gas chamber 34 fluidically communicating with the gas tube 21, so that gas can be continuously introduced into the gas-mixing chamber 41 along the gas passageway 32a. As described above, the oxygen-adjusting part 30 controls only interception and inflow of oxygen.
[21] As described above, since the gas-adjusting part 10 controls only the interception of gas introduction and the oxygen-adjusting part 30 controls only the interception of oxygen introduction, when the welding torch is used actually, it can form good flame by properly controlling the gas-adjusting part 10 and the oxygen-adjusting part 30 when it is used. However, when the welding torch is not used, introduction and gas and oxygen can be simultaneously intercepted by the gas-adjusting part 10 and the oxygen- adjusting part 30.
[22] Meanwhile, as shown in an enlarged view of a circular part in FlG. 2, a scale 23 is indicated on the outer peripheries of both ends of the welding torch hand grip 20, on which the gas-adjusting part 10 and the oxygen-adjusting part 30 are mounted, for precisely and easily controlling inflow of gas and oxygen, whereby even an unskilled person can easily make a mixing ratio of good flame. Industrial Applicability
[23] As described above, the straight type welding torch according to the present invention allows even the unskilled person to easily set the mixing ratio of good flame using a scale indicated on the outer periphery of a hand grip thereof, and prevent the user's sleeve from being caught to the gas or oxygen-adjusting part during welding.
[24] While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
