変化させながら塗装作業を進めていた。[Conventional technology] Air spray guns for painting are used for vehicles such as automobiles and ships.
l Except when used in a painting facility, a spray gun, which is generally connected to a long hose for replenishing paint solution and compressed air, is usually held by a spray gun and used to paint a workpiece with a complex external shape. The painting process was progressing while constantly changing the support state of the gun toward the surface.

いた。[Problems to be Solved by the Invention] When operating the above-mentioned painting spray gun, although the hoses are quite flexible, the two hoses may be bundled together, or Even if they remain unbundled, due to their structure, the ease with which the hoses can be bent as a pair when performing spray operations while swinging the spray gun has a certain direction. It has to happen. For this reason, it is difficult to control the gun to change the spray direction of the gun as smoothly as desired, which is one factor that hinders improvement in painting efficiency.

かった。Also, if these hoses become dirty with paint,
Not only was it time-consuming to wash each of the two wooden hoses using a solvent, but it was also difficult to store the hoses compactly when not in use.

One end of the inner tube is fitted into the outer joint, and one end of the outer tube for gas delivery is fitted into the outer fitting. In the same way, assembly of the device is completed by attaching one end of each of the liquid and gas delivery tubes to the inner and outer joints of a pair of tube joints coaxially provided with the discharge joint. .

らなる配管の末端継手に接続する。The method of using this device is to install the liquid and gas inlet joints of the piping joints for introducing liquid and gas close to the place where the device is used, and to connect the piping joints to the ends of the piping connected to the liquid or gas supply source. Connect to the fitting.

るようになる。Conventionally, liquid (paint) and gas (paint) and gas ( Compressed air ) and two hoses for each delivery lined up in one gun! Instead of having to connect fi1, a single coaxial tube is now sufficient, so there is no need to tangle multiple tubes or bundle multiple flexible tubes as in the past. This eliminates the problem that the ease of bending of the tube bundle becomes directional when used, which causes the smoothness of the swinging operation of the dispensing gun to be lost, resulting in a significant decrease in work efficiency. , the storage space for the discharge SR is also reduced.
