The socket) 20 is fixedly attached to the base 19 of the cylinder 18.

Figure 6 shows the mechanism of the one-touch joint (plug) 21, including a cylinder 27 that forms the plug body, a valve 28 that controls gas supply and stop, and a guide for opening and closing the valve 28 uniformly. It consists of a shaft 29, a guide 30 for sliding this guide shaft 29, a spring 31 for keeping the valve 28 closed, and a fixing ring 32 for holding the blade of this spring 31.

The guide 30 is provided with holes that serve as gas passages.

FIG. 7 shows the mechanism of the touch-type joint (socket) 20, which includes a cylinder 33 forming the socket body,
A valve 34 that controls gas supply and stop, and a valve 34
A guide shaft 35 for opening and closing uniformly, and this guide shaft 3
a guide 36 for sliding the valve 5, a spring 37 for keeping the valve 34 closed, and this spring 37.
A fixing ring 38 for holding the force of the plug 21, and a bearing 39 for smoothly inserting the plug 21.

a stopper 40 for preventing the plug 20 from coming off;
A detachable ring 41 that slides when attaching and detaching the 20 ft plug, a spring 42 that holds the detachable ring 41 in place with the plug 20 inserted, and a spring 42 to prevent the detachable ring 41 from falling off the cylinder 33. and a stopper 43. The guide 36 is provided with holes that serve as gas passages.

9 and 10 show the bottom of the cylinder 18, which is composed of a concave bottom plate 44 and a handle 45 attached to the bottom plate 44.

11 and 12 show the bottom of the cylinder 18, which is composed of a cylinder 47 attached to the outer periphery of the bottom and a handle 48 attached to the cylinder 47.

1 to 8h, the cylinder 18 is placed on the base plate 9 and the one-touch joint (
By pulling the detachable ring 41 of the socket) 20 toward the base 19, the stopper 40, which serves as a ring spring by cutting an arbitrary part of the ring in the outer circumferential direction, expands in the outer circumferential direction and is attached to the base 22 in this state. By inserting the cylinder 27 and returning it to its original state by the detachable ring 41ft spring 420, the stopper 40 is pushed inward and fixed in the recess of the cylinder 27, preventing the cylinder 27 from coming off and at the same time closing the valve. 28 and valve 3
4 are pushed against each other by the repulsive force of the spring 31 and the spring 37, and the valve 28 and the cylinder 271, the pulp 34, and the cylinder 33 are all in an open state, and the cylinder 18
The empty gas passes through the holes provided in the guide 36 and the guide 3o, and the pipe 231 pulp 24. It passes through the pipe 25 and is stored in the chamber 13, and is connected to the pressure reducing device 14 and the flow meter 15.
- Supplied to the welding area via the gas hose 16.

By pulling the detachable ring 41 toward the base 19, the stopper 40 expands outward and comes out of the recess of the cylinder 27. By pulling out the cylinder 27 in this state, the pulp 2
The pulp 34 of the spring 31 is pushed by the repulsive force of the spring 37, and the pulp 28 and the cylinder 27.
The space between the pulp 34 and the cylinder 33 is closed, and the gas supply from the cylinder can be stopped and the gas inside the pipe 23 can be prevented from flowing. This one-touch joint attachment/detachment operation is suitable for supplying and stopping the welding shield gas filled in the cylinder.

According to this embodiment, the cylinder can be easily installed and removed within the welding power source, eliminating the need for valve opening/closing tools such as spanners and wrenches, and reducing the preparation time for supplying shield gas for welding by half, making it possible to perform one task. becomes convenient.

When transporting or moving the welding power source, the cylinder can be connected at the same time so that it can be easily transported or moved.

Since the cylinder is installed inside the welding power source, there is no need to extend the gas hose from the cylinder to the welding power source.
Gas hose damage and wear are eliminated, improving safety.

Since all the cylinders are installed inside the welding power source, there is no need to prepare the cylinder room completely, saving space, and therefore, welding setup time in a narrow space can be halved.

By keeping the weight of the cylinder below 30KF and having the bottom of the cylinder structured as shown in Figures 9 and 10, or Figures 11 and 12, the cylinder can be easily installed in the welding power source by one person. There are things you can do.

Pipe 23. By making the pipe 25 made of copper, it can be more easily attached and detached than a one-touch joint.

Also, by attaching rollers to the cylinder stand, cylinders can be easily moved.

In addition, in the figure, 3 is an upper lid, and 46 is a bottom plate.

〔Effect of the invention〕

According to the present invention, there is no need to place a cylinder separately from the welding power source. Also, it becomes easier to install and remove the cylinder.
