The connection end of the pipe member through which the required pressurized fluid flows is removably fitted to the connection plug mechanism with a single touch, and is restrained and pulled at the fitting position (connection position). In many cases, it is configured to be locked and locked, and many proposals have already been made conventionally.

[0003] In this case, the connection plug mechanism includes a strapping member that elastically sandwiches the outer peripheral surface of the connection end of the pipe member and detachably restrains the inside of the mechanism inside the mechanism. A tube member to be connected to each of the constituent members for giving the banding action to the banding member, and an operating member for releasing the constraint. It is necessary to pinch and restrain the peripheral surface of the connection end, and for example, synthetic resin such as polyurethane, polyamide (trade name, nylon), polyethylene, polytetrafluoroethylene (trade name, Teflon) A hollow tube such as a connection tube made of a material as a main material and having some surface elasticity is used.

[0004]

However, in the case of the connecting plug mechanism of the pipe member used by being incorporated in the above-mentioned conventional equipment, pipe joints, etc., the specification of incorporating the pinching means into the connecting structure is extremely small. There was a regret that various and diverse, not necessarily simple, effective and good incorporation of the clamping means.

[0005] The present invention has been made to solve such a conventional problem.
The connection space formed in the connection structure portion of the connection plug main body in equipment devices, pipe fittings, etc. is previously dimensioned to a predetermined size, and the inside of the connection space can be easily assembled and provided with the intended pipe member.

[0030]

As described above in detail in each embodiment, according to the tube member connecting plug stopper module of the present invention, the outer peripheral surface of the connection end of the tube member is elastically sandwiched. Since the structure of the strapping means for detachably retaining and restraining is modularized, the modularized strapping means is simply fitted into the connection structure such as the connection plug main body, and this is appropriately connected to the connection axis. The entire apparatus can be easily configured simply by restraining the apparatus from moving in the direction. Then, in this assembled state, the lock ring member is engaged with the lock ring member by an extremely simple operation of inserting the connection end portion of the pipe member through the release ring member corresponding to the connection end side. It is possible to perform one-touch connection by pinching, and it is possible to release the pinched state only by pushing in against the elasticity of the lock ring member in the connection direction of the release ring member and perform one-touch detachment. It is also relatively simple in structure and can be easily implemented.

In addition, according to the elastic lock ring member of the present invention, in each operation of one-touch connection and detachment of the pipe member to and from the connection plug device, the swinging movement of each of the strangulation connecting portions is smoothly performed, and the acting force is obtained. The disadvantages such as breakage due to the concentration of the liquid can be eliminated, and a good retaining and restraining mode can always be maintained.
