7が確実に挿入された事が判明できることとなる。Next, the connection and disconnection of the pipe joint and the male plug 27 will be described in more detail with reference to FIGS. 6, 7, and 8 as an example. In this example, when the male plug 27 is inserted into the socket 5 of the pipe joint in the state shown in FIG. 6, the tip 28 is inserted without coming into contact with the lock member 13, and the sealing material 4,
While being in contact with 4, it is further inserted inside. In this insertion process, as shown in FIG. 7, the front taper portion 29 of the male plug 27 comes into contact with the lock member 13 and pushes the lock member 13 and the sleeve 12 into the joint deep portion side against the bias of the spring member 11. Act on. Then, when the lock member 13 reaches the moving space 14 of the outer cylinder 17, the lock member 13 rides over the large diameter portion 30 of the male plug 27 and falls into the annular groove 32. Then, the sleeve 1 is biased by the spring member 11.
When the sleeve 2 is pushed back, the sleeve 12 comes into contact with the inner surface of the outer cylinder 17 and makes a contact sound. Therefore,
As shown in FIG. 9, when the male plug 27 is completely inserted, the lock member 13 and the annular groove 32 are fitted to each other, and the contact sound of the sleeve 12 is confirmed to confirm the male plug 2
It can be confirmed that 7 has been securely inserted.

合したか否かは容易に判断できることとなる。However, in the middle of insertion as shown in FIG. 7, the lock member 13 does not fit into the annular groove 32, and therefore the contact noise between the sleeve 12 and the outer cylinder 17 does not occur. Since the male plug 27 has no restraint force, the male plug 27 is pulled out with a small force, and it can be easily determined whether or not the male plug 27 is completely connected.

7の離脱を防止することができるのである。In the state shown in FIG. 8 in which they are completely connected in this manner, the stopper member 34 is moved to the female body 1 side, and the inner surface concave groove B of the outer cylinder 17 is once aligned with the position of the outer surface convex portion C of the socket 5. Unless the convex portion C is pushed to the pipe joint side, the outer cylinder 17 cannot be pushed. Therefore, even if the force for pushing the outer cylinder 17 is carelessly applied, it cannot be pushed in actually, and the male plug 2
It is possible to prevent the separation of No. 7.

雄プラグ27の管継手からの引き抜きが阻止される。Now, as shown in FIG. 8, when the male plug 27 is completely inserted and force is applied to pull out the male plug 27, or when a fluid is flown into the male plug 27, that is, When a force acts in the direction of pulling out the male plug 27, the lock member 13 is pressed against the inner surface projection 16 of the outer cylinder 17 and the taper hole 10 of the socket 5 to be restrained, and cannot be jumped out of the annular groove 32. ,
The withdrawal of the male plug 27 from the pipe joint is prevented.

される。On the other hand, when the male plug 27 is to be removed from the pipe joint, the stopper member 34 is moved to the female body 1 side as shown in FIG. It suffices that the positions of B and the convex portion C on the outer surface of the socket are temporarily aligned and moved to the female body 1 side. And male plug 27
When is pulled, the lock member 13 moves to the moving space 15 of the outer cylinder 17 at the rear taper portion 31 of the male plug 27. Therefore,
Since the lock member 13 gets over the large diameter portion 30 of the male plug 27 and the coupled state is released, the male plug 27 can be easily pulled out from the female body 1. Further, since the valve body 18 is also released from the pressing force of the male plug 27, the valve body 18 is moved to the taper portion of the female body 1 by the bias of the spring member 20 and the pressure of the fluid, and the passage of the fluid is blocked by the sealing material.

A concave groove is provided on the outer surface so that the convex portion of the outer cylinder can slide, the stopper member is moved from the movement space of the outer cylinder, and the convex portion on the inner surface of the outer cylinder is aligned with the position of the concave groove on the outer surface of the socket. Sometimes, the socket can be moved to the female side, and the male plug can be attached to and detached from the socket. In this case, the other specifications can be the same as described above.
