Description of the Related Art Conventionally, a joint for connecting a flexible pipe formed in a bellows shape (hereinafter sometimes referred to as a flexible pipe) has been disclosed in, for example, Japanese Patent Publication No. 3-3837 shown in FIG. There is something. In connecting the joint and the flexible pipe, first, the cap nut 83 is inserted into the flexible pipe 10, and the retainer 80 having the inner surface for engaging the corrugation and having the slit in the axial direction is opened to open the distal end of the flexible pipe. Attach to the section. After that, insert this into the large diameter hole 85 of the joint body 88, screw the female thread 82 of the cap nut and the male thread 84 of the joint body, and make a few peaks protruding from the end surface of the retainer 80 to the end surface of the retainer 80. And the gasket 89 are crimped, that is, crushed and connected, which is called, for example, a tightening type.

ある。In addition, there is another disclosed in Japanese Utility Model Laid-Open No. 3-73785. In this joint, as shown in FIG. 10, the joint body 90 and the tightening member 91 are preliminarily assembled, and a snap ring capable of expanding the diameter is provided.
93 is arranged between the tip surface of the tightening member 91 and the packing 92, the snap ring 93 is expanded while passing through and the flexible pipe 10 is inserted, and then the tightening member 91 is fully added to the joint body 90. Retaining ring 93 while tightening to prevent expansion of retaining ring 93
The packing 92 is pushed in to crush and connect several peaks of the flexible pipe in front of the retaining ring 93 to the inner wall 94 of the joint body, which is called, for example, a retightening type.

いる。Recently, there has been proposed a so-called one-touch type joint (for example, Japanese Patent Laid-Open No. 5-164280) in which the connection is completed by pushing the flexible pipe into the joint body, but in the case of this joint, the tightening work and the additional tightening are performed. Since it has no function, it cannot be completely sealed by crushing the tip of the flexible pipe. Especially for gas, it is not preferable if there is concern about the sealing performance.
Actually, as in the above-mentioned two examples, the tightening type and the retightening type which crush at least a few peaks of the flexible tube are put to practical use.

る上にフレキ管の先端数山(2〜5山)を押しつぶすか

ナットを何回転もしなければならないのでその分時間が
長くかかる。The former one of the above-mentioned conventional flexible pipe joints has a problem that it takes time and labor for connection work because the joint parts are once disassembled and then assembled. Originally, this is a tightening work that involves friction, and since several tips (2 to 5 threads) of the flexible pipe are crushed, a considerable force is required for this tightening work, and the cap nut must be rotated many times. So it takes a long time.

る。In the latter case, the connection is completed only by preliminarily preliminarily preliminarily assembling the flexible tube and then tightening it again, so that the working time is relatively short. However, since several peaks of the flexible tube are to be crushed to the inner wall here, the additional tightening amount of the tightening member is set to an amount corresponding to the pitch of approximately three peaks of the flexible tube. The problem here is that there is no guarantee that the three peaks will pass through the retaining ring when the flexible tube is pushed in, and there is no means for confirming this. That is, even if it does not pass through one or two mountains, the amount of tightening is the same. In such a case, even if additional tightening is performed, the tightening amount for two peaks or one peak is insufficient, and there is a problem that the peaks cannot be crushed completely and leakage occurs from here. In order to solve this problem, it is conceivable to give a margin to the additional tightening amount, for example. However, in this case, since the number of screwing rotations of the tightening member is further increased, there is a problem that a large amount of force and time are required for the connection work as in the previous example.

間が短縮される。First, in the case of the tightening type flexible pipe joint, since the tip of the flexible tube is crushed by only one ridge, the tightening force, especially the force of crushing the ridge after abutting against the back wall is reduced. Further, the rotation of the nut is reduced, and the time required for connection work is shortened.

ても上記と同様の作用をなす。Next, in the case of a retightening type flexible pipe joint, the joint body and the nut are pre-tightened in such a manner that the distance between the front end of the retainer and the back wall allows only one tip of the flexible pipe to pass. It is assembled with leaving. That is, 1
When the mountain passes through the front end of the retainer, the tip collides with the inner wall and cannot move any further. In this state, if the flexible pipe is once pulled out, the flexible pipe cannot be pulled out because the front end portion of the retainer is locked in the first valley portion. This makes it possible to confirm that the flexible tube has been properly inserted.
Conversely, if you try to pull out the flexible tube and it actually comes out, the tip still has not passed through the retainer by one ridge, and you can see here the need to push it in further. Further, as with the tightening type, the force required for tightening and the time required for connection are shortened. still,
The same operation as described above can be achieved in a case where the retainer in the expanded diameter state is reduced in diameter due to the insertion of the flexible pipe to crush one peak at the tip.

1 and an annular guide body 32 having an engagement protrusion that is fixed to the rear end of the engagement portion to hold the engagement portion 31 in an annular shape and engages with the engagement groove 24 of the nut 20. The retainer 30 including the locking portion 31 and the guide body 32
Are locked to the nut 20 so as to be rotatable and axially movable. In this case, since the guide body 32 is made of resin, the guide body 32 is inserted into the engagement groove 24 while being slightly contracted in the inner diameter direction so that the guide body 32 is fitted into the snap groove. The locking portion 31 of the retainer 30 and the guide body 32 may be integrally formed of resin as long as the strength is sufficient for crimping the distal end portion of the flexible pipe. 32 may be formed of a resin and fixed integrally with an adhesive, or both may be formed of an integral metal having elasticity. Further, the front end surface 33 of the locking portion 31 has a single projecting shape that locks to the first valley portion 7c of the flexible tube 7 in the figure, but it has a plurality of locking peaks other than one peak of the flexible tube 7 at the tip. It may be wave-shaped.

を保持している。Next, the procedure for connecting the flexible pipe joint of this embodiment will be described. FIG. 2 shows a state before the flexible pipe 7 is inserted. First, in the joint body 10 and the nut 20, the distance between the front end portion 33 of the retainer 30 fixed to the nut and the inner wall (including the gasket 40 in this case) is set. , With a retightening amount such that when one tip of the flexible pipe gets over and comes into contact with the back wall, it is locked in the next valley (first valley), that is,
When one mountain passes through the front end portion of the retainer, the tip end is pre-screwed to a position where it collides with the inner wall and cannot move further. On the other hand, at this time, the locking portion 31 of the retainer 30 is also in a state in which the diameter can be expanded in the annular recess 16 of the main body 10. In other words, the front end portion 33 of the locking portion 31 has the reduced diameter hole portion 1
The position is such that it does not fit in 7. A collar 34 is attached between the ends of the main body 10 and the nut 20 to maintain this screwed state.

確認することになる。Next, when the flexible pipe 7 to be connected is inserted from the rear end of the nut 20, the first first mountain portion 7b of the flexible pipe 7 pushes the front end 33 of the retainer 30 and spreads it, as shown in FIG. I slipped through, hit the back wall, and couldn't move any further. In this state, the front end portion 33 is fitted and locked in the first valley portion. Therefore, even if the flexible pipe 7 is pulled out here, the front end portion does not come out of the joint body by engaging with the valley portion. If further pulling out is attempted, the front end portion fits into the inner diameter surface on the front side, and pulling out can be prevented more strongly. On the contrary, if the flexible pipe comes out here, it means that no one ridge has passed through the front end portion 33 of the retainer, and it is confirmed that further pushing is necessary.

終了する。Next, the collar 34 is removed, and the nut 20 is rotated and tightened to the joint body 10 again. As shown in FIG. 4, the front end surface 25 of the nut 20 abuts against the rear end surface of the guide body 32 of the retainer 30 and is locked. The part 31 is pushed into the reduced diameter hole 17.
Therefore, the front end portion 33 of the locking portion 31 is completely fitted into the first valley portion and pressed toward the back wall side while reducing the diameter of the first peak portion of the flexible tube 7. At this time, the nut 20 is rotated, but the retainer 30 is rotatably engaged with the nut 20. Therefore, the retainer 30 is locked by the friction resistance reduced by the diameter reducing hole 17 and does not rotate. In this way, one peak at the tip is sandwiched between the retainer and the back wall via the gasket, and this sandwiching completely seals the flexible pipe and the joint body. Further, after the tightening is completed, the O-ring 50 and the T-type packing 60 perform external sealing, so that corrosive water does not enter the connection portion. As described above, the connection of the flexible pipe 7 is completed.
