Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an extension type flow tube gas torch,

The present invention relates to a gas torch, and more particularly, to an elongated flow tube gas torch capable of adjusting the length and direction of the torch so that the welding or cutting operation can be performed more easily.

Generally, a gas torch is connected to a gas container at the time of gas welding or cutting, and is configured to burn out a gas to be spouted and injected, thereby spouting a flame, and sparks suitable for use such as welding, cutting,

However, in the conventional gas torch, since the guide pipe guiding the gas is made of a metal material, the length of the gas torch is uniform, and it is inconvenient to cope with the situation of the work site.

On the other hand, as a conventional technique for improving this, Patent No. 1036557 has proposed a technique relating to a tip for extending a gas torch which can be used by being connected to the head portion of a gas torch.

However, the extension tip of the gas torch in the above-mentioned conventional technique is capable of extending the length of the torch but it is impossible to adjust the direction, and the operator also performs the connection work at the work site And the like.

The present invention has been proposed in order to solve the above problems in the prior art, and it is an object of the present invention to provide a technique for easily controlling the length and direction of the gas torch according to the working conditions in the field, To be able to do so.

According to an aspect of the present invention, there is provided a gas torch comprising a head part for spark ignition, a guide tube for guiding gas to the head part, and a handle part connected to one side of the guide tube, And a flexible tube of a metal material surrounding the inner tube; The guide pipe and the grip portion are formed in a detachable structure. The bolt portion is integrally formed at one side of the handle portion, and the fastening nut is formed at one end of the guide pipe corresponding to the bolt portion.

The gas torch according to the present invention can change the length of the gas torch and change the direction of the gas torch according to the work site conditions, thereby achieving more effective gas cutting and oxygen welding.

1 is a side view of an extended gas torch according to an embodiment of the present invention;
2 is an elongated gas torch separation view of the present invention.
Fig. 3 is a view showing a state where the extension type gas torch length adjustment guide tube is replaced with the present invention. Fig.
4 is a state in which the elongated gas torch direction of the present invention is adjusted.
5 is a cross-sectional enlarged view of a gas torch guide tube according to another embodiment of the present invention.
6 is a detailed sectional view of a guide tube detachable section of a gas torch according to another embodiment of the present invention.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 through 4, a gas torch according to an embodiment of the present invention includes a head portion 10 for spark ignition, a guide tube 20 for guiding gas to the head portion 10, And a handle 30 connected to one side of the guide pipe 20. The handle 30 is provided with a gas control valve 31 for controlling the amount of gas supplied to the handle 30 and a connection It is possible to confirm that the hose connection port 32 is provided.

In particular, the guide tube 20 of the present invention has a double structure of an inner tube 21 made of a heat-resistant material and a flexible tube 22 made of a metal and surrounding the inner tube 21.

The guide pipe 20 and the handle 30 are constructed in a detachable structure so that the bolt 35 is integrally formed on one side of the handle 30. The bolt 35 is provided in correspondence with the bolt 35 A fastening nut 25 is formed at one end of the guide tube 20.

Hereinafter, effects of the gas torch according to the present invention will be described.

First, when it is desired to carry out gas cutting or oxygen welding work in the industrial field, after the gas supply hose is connected to the hose connection port 32, the operator grips the handle 30 and adjusts the gas control valve 31 .

At this time, when the working space is narrow or not easy according to the field conditions, the length of the guide pipe 20 may be changed or the direction of the guide pipe 20 may be adjusted.

That is, if it is necessary to change the length of the guide pipe 20, the coupling nut 25 at the connecting portion with the handle 30 is rotated to separate the bolt 35 from the bolt 35, The prepared guide tube 20 is replaced with the handle 30 and used.

When the direction of the guide tube 20 is required to be adjusted by applying a force to the guide tube 20 as shown in FIG. 4, the operation of the flexible tube 22 is facilitated Direction adjustment can be performed.

Accordingly, when the gas torch of the present invention is used, the length and direction of the gas torch can be adjusted according to the situation of a work site, thereby achieving an optimum working efficiency.

5 shows a gas torch structure according to another embodiment of the present invention in which a shape is formed between the inner tube 21 and the flexible tube 22 so that the state of change of the guide tube 20 can be stably maintained. A coil wire 23 made of a memory alloy is wrapped around the inner tube 21 in the form of a coil and the coil wire 23 has protrusions 23a protruding outward for increasing the contact area with the inner tube 21 .

In this case, since the inner tube 21 located inside the flexible tube 22 is supported by the coil wire 23, it is possible to prevent the deformation of the coil tube 23 due to the change of direction, The contact area with the inner tube 21 can be increased by the protrusion 23a, so that a more stable supporting action can be achieved.

6 shows a structure according to another embodiment of the present invention. It can be seen that a guide portion 33 for guiding the coupling of the coupling nut 25 is protruded at one side of the handle portion 30. As shown in FIG.

With such a structure, guide can be made by the guide portion 33 in the fastening process of the fastening nut 25, thereby preventing the occurrence of the flow after fastening with the bolt portion 35, So that it is possible to maintain the fastened state of the fastener.
