At the time when the end portion 56 passes the corresponding position of each engagement ball 34, under the elastic force of the pressing spring 66 of the release mechanism portion E, the operation cam surface 65 constantly presses the inner peripheral surface side. The inner portion of the engagement ball 34 falls into the engagement circumferential groove 105 and abuts and engages with the rear inner surface to restrain and secure the male joint member 101 at a corresponding position, and the engaged engagement members. The compound ball 34 is pressed toward the outer peripheral surface side by the cam action of the contact surface due to the elastic force of the pressing spring 57 that is simultaneously stored,
Further, with the depression engagement, the release member 6 is turned in turn.
1 moves to the front side with the opening / closing member 41 left (while remaining at the valve closing position) (the "blue" display is exposed), and the outside of each engagement ball 34 pressed to the outer peripheral surface side. The portion is restrained and held by the sixth sliding surface 64, and the operating cam surface 65 is abutted against the cam pressure receiving surface 35. That is, this is the valve closed state shown in the upper half of FIG. 2, and the plug-in connection of the male joint member 101 to the required pipe joint body A here is completed by the above insertion and pushing operations.

The opening / closing member 41 is released from the restraint by the release member 61, so that the opening / closing member 41 can be independently opened. In this case, the "red" display is covered (not exposed) and the "blue" display is opened (exposed). Further, the pushing operation at this time may be performed merely against the elastic force of the pressing spring 57, and the primary side internal flow path 1
It can be done very easily without any influence from the pressurized fluid introduced at 0a.

出がなされる。Next, as the release member 51 in the release mechanism section E slides forward, the opening / closing member 41 left in the valve closing position is slid forward in the valve opening direction. When operated, the communication passage 43 that has been maintained at the outer peripheral side of the primary side communication port 23 until then, has kept the on-off valve equivalent part of the on-off valve mechanism section B in the closed state. Is moved (opened) to a position straddling the secondary side communication port 24, and the primary side communication port 23 and the secondary side communication port 24 are connected via the communication flow path 43.
As a result, the primary side internal flow channel 10a and the secondary side internal flow channel 10
As a result, the opening / closing valve equivalent portion shifts to the valve open state. That is, this is the valve open state shown in FIG.
By the above sliding operation, the pressurized fluid is led out from the required primary-side internal flow channel 10a to the secondary-side internal flow channel 10b.

Sliding operation to the rear side together with that, that is, here, the opening / closing member 41 is located across the outer peripheral side of the primary communication port 23 and the outer peripheral side of the secondary communication port 24. By performing the valve closing operation so that the communication flow path 43 is located only on the primary side communication port 23 side, on the one hand, the primary side communication port 23 and the secondary side communication port 24 are closed (valve closed) and closed. The valve state shifts, and the “blue” display is gradually covered (non-exposed) while the “red” display is gradually covered (non-exposed), and at the same time, each engagement by the sixth sliding surface 64 is performed. The engagement maintenance of the outer portion of the ball 34 is released, and the engagement balls 3 Since a pressure force is applied to the outer peripheral surface side by the stored pressure spring 57, the force is pushed toward the outer peripheral surface side, and the restraint on the male joint member 101 is also released. The release member 61 is returned, and at the same time, the female joint member 41 of the joint mechanism portion C is also returned.

実施できる等の優れた特長を有するものである。As described above in detail with reference to the embodiments, according to the present invention, a pipe joint body having an opening / closing valve corresponding portion for opening and closing the internal flow passage is provided, and the internal flow passage of the pipe joint body is provided. Plug-in connection in which an external male joint member is plug-in connected to a female joint member arranged in the same, and an engaging member is provided for restraining and holding the male joint member to be plug-in connected at a connection position. In a type fitting device, an opening / closing valve mechanism part in which the opening / closing valve equivalent part is opened / closed in the fitting body and the female type fitting member is constantly pressed to the non-connection side. A male joint member having a first elastic pressure means for holding the engaging member on the non-restraining side when not connected by the elastic pressure and releasing the engaging member to the restricting side when connecting to connect against the elastic pressure. And a release mechanism that is linked to the engaging member and the opening / closing member. Then, a second elastic means for elastically pressing the engagement member to the restraining side is provided, and the opening / closing member is maintained in the valve closed position when not connected, and released when connected to allow the valve opening and closing operations. The plug-in connection of the male joint member from the outside to the female joint member of the joint mechanism and the connection position by the engaging member while the pipe joint body is in the non-connection closed valve state. Is easily possible without being affected by the pressurized fluid pressure introduced,
Further, the opening / closing valve corresponding portion can be optionally opened / closed by the operation of the opening / closing member in the opening / closing valve mechanism portion, and further, the engagement holding with the male joint member can be held by the operation of the releasing member in the releasing mechanism portion. Not only can it be released, but the part corresponding to the on-off valve can be returned to the closed state so that the male joint member can be easily plugged out, and the structure is relatively simple and easy to implement. It has features.
