Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a tube and hose connection device for pressure piping.

[0002]

[Prior art]

 Fig. 6 shows an example of a typical tube-hose connection part of this type. When connecting the tube and hose in such conventional pressure piping, use both hands as shown in Fig. 5 and use a spanner. While fixing the hose side base with, the sleeve nut was tightened or loosened with the normal torque wrench shown in Fig. 7.

[0003]

[Problems to be solved by the device]

 In connection with the conventional tool described above, in order to prevent twisting of the hose, it is difficult to tighten the sleeve nut with a torque wrench while adjusting the fixing mouthpiece so that it does not rotate together, and it was a problem that skill was required.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above problems, and uses a tool that fixes the hose side and the tube side at the same time and enables the sleeve nut to be tightened with a torque wrench. This tool is characterized by using a quick wrench for one of the two wrenches.

[0005]

[Action]

 By using the tool of this invention, the hose side and the tube side are fixed at the same time, so that no matter what angle the screw is tightened, the hose will not twist and can be easily removed when disassembling.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a perspective view of a tool 1 for fixing the hose side and the tube side at the same time, FIG. 2 is a side view of the quick wrench side of FIG. 1, which is a view taken in the direction of arrow B, and FIG. 3 is a side view of the spanner of FIG. The A arrow view is shown. And FIG. 4 shows an example when using the tool 1. Referring to these drawings, a quick wrench is used as the wrench 1a for fixing the mouthpiece 2 on the hose side, and it can be locked so as not to come off while fixing. When the lock is released, it can be easily removed by the knob 1b.

When using this tool, first the tube side cap 4 is fixed by a spanner 1c, and then the hose side cap 2 is gripped by a quick wrench 1a to prevent the tool 1 from falling off. If the tool is pressed in this state and the sleeve nut 3 is tightened with a torque wrench, the hose can be easily attached without being twisted. After the installation is completed, the quick wrench 1a may be opened by the knob 1b and the tool 1 may be removed.

[0008]

[Effect of device]

 This invention is made as described above, and even if not a skilled person, the hose will not be twisted, and the hose can be easily installed and there will be no interference with the frame or the like. In addition, you can work easily because you do not need to use both hands.
