Couplings for High Pressure Hose {COPLING FOR HIGH PRESSURE HOSE}

The present invention relates to a coupling for a high pressure hose, and more particularly, to couple the high pressure hose to one side of the main body of the coupling, and to couple the clamp to the coupling body by coupling the clamp to the outer surface of the high pressure hose. By tightening the high pressure hose can be easily and firmly fixed to the coupling body to save the cost, and relates to a high pressure hose coupling that can shorten the working time.

In general, when the high pressure hose coupling transmits high pressure to a device far from the high pressure actuator including the high pressure cylinder, a female or male coupling is installed at one end of the high pressure hose connected to the high pressure actuator, and the high pressure hose connected to the other device. Male or female couplings are installed in the female and female and male couplings are conveniently used.

However, the coupling as described above has a problem in that the coupling and the high pressure hose are separated by the high pressure of the air or oil conveyed to the high pressure hose.

In order to solve the above problems, in recent years, the coupling for the high pressure hose is combined with the high pressure hose to the coupling and then fixed band or fixed after inserting the fixing band or fixing ring on the outside of the high pressure hose so that the coupling and the high pressure hose is not separated. A method of punching the ring or using a device such as a price or a press to press the outside to prevent the high pressure hose from being separated from the coupling is used.

However, the coupling for the high pressure hose as described above requires a separate operation to press the fixing band or the fixing ring in order to fix the high pressure hose to the coupling, there was a problem that such work is impossible in the field.

Therefore, in order to connect the high pressure hose to the coupling, there is an inconvenient problem of removing the coupling and moving to a place where a device such as a press is installed. As described above, the coupling must be removed and moved until the coupling is reinstalled. There was a problem that the operation was interrupted.
