Description

The present invention relates to a coupler device for high water pressure, and more specifically, a coupler is fixed by using a separated fixing member, and is fastened by connecting an elastic member to an outer surface of the fixing member to prevent the dropping. The present invention relates to a coupler for high water pressure that is easy to reduce, is reduced in size and weight, and is prevented from being loosened by carelessness of the user.

In general, a coupler is a connector for connecting one member to another member, and in particular, between pipes such as pipes, tubes, and pipes for transporting fluids such as gas and liquid. It is a device used for connecting and disconnecting.

In order to prevent the fluid from leaking from the connection part of the pipe and the foreign substance from flowing in from the connection part of the pipe as described above, the coupler is a male coupler. In general, the male coupler is formed so that the male coupler is drawn into and coupled to the inside of the female coupler.

Conventionally, a male coupler and a female coupler are coupled by a method such as screwing, or the outside of the coupler is formed so as to be wrapped with a clamp, and the clamp is screwed to connect the fluid inside the pipe. The method of transporting was used.

However, in such a case, it is difficult to connect and separate the screw because the user must tighten the screw by applying an external force of a certain size or more with the coupler connected, and in some cases, the screw may be tightened or loosened. There is a problem that an additional device is required.

In general, since coupling members such as bolts, nuts, and screws are made of a metal material, there is a problem that the weight of a coupler apparatus for coupling pipes increases.

When the connecting member is worn, there is a problem that a space difference of the thread contact portion occurs and unintentional loosening of the fastening occurs, and there is a problem that the fastening is loosened by an external force such as vibration or impact.

On the other hand, a recessed groove is formed inside one of the male coupler and the female coupler, and a protruding ball is formed inside the other, so that one of the male coupler and the female coupler is already attached. A method of fastening by being coupled to one of the grooves is also used, but in such a case, there is a problem that the fastening of the coupler is easily loosened due to an external force or carelessness of the user.

Therefore, a method for solving such a problem is required.
