Formed through hole 4a on the maintenance tube 4 of above-mentioned joint body 2, the maintenance ball 9 that is used for moving sleeve 6 is remained on the position of Fig. 2 can be entrenched among the described through hole 4a with moving radially with a gap.And, keeping tube 4 upper edges circumferentially to form circular-arc upper-side hole 4b and lower-side hole 4c, they have chimeric with gap upside card claw stop 16 and downside card claw stop 17 and it can radially moved in inside respectively.On the inner peripheral surface of this upside card claw stop 16 and downside card claw stop 17, form the female thread portion be used for engaging and keep formpiston pipe joint 50 with the outer screw section 52 of formpiston pipe joint.This female thread portion form can imagination by the continuous worm tooth of upside card claw stop 16 and downside card claw stop 17, among Fig. 2, the worm tooth that shows upside card claw stop 16 and downside card claw stop 17 state of half spiral shell square that just in time staggers.
The trigger component 13 that in keeping tube 4, is keeping ring-type slidably.This trigger component has the ball of maintenance dump tank 35, can be accepted to keep ball 9 and will keep ball to separate from moving sleeve by this groove, makes this moving sleeve forwards mobile.Radially inner side at trigger component 13 is being provided with the inboard cylindrical shell 11 that forms the tubular of stream when connecting formpiston pipe joint 50.Inboard cylindrical shell 11 is made of large-diameter portion 11a that clips stepped part 11c and minor diameter 11b, is setting the rear end bullet along the inner peripheral surface of large-diameter portion 11a and is sending out mechanism's (helical spring) 10.Inboard cylindrical shell 11 is pushed to the place ahead (right-hand) by the elastic force that described rear end bullet is sent out mechanism 10 always, under the state that does not insert formpiston pipe joint 50 (Fig. 2), is in the positions that the trigger component 13 that engage with inboard cylindrical shell 11 is shifted maintenance balls 9 onto the radial outside position.Front end at formpiston pipe joint 50 is formed with plane of inclination 53.And when former pipe joint 1 had been connected with formpiston pipe joint 50, the minor diameter 11b of inboard cylindrical shell 11 engaged with the perisporium of the stream 54 of formpiston pipe joint 50.
Axial direction two end part at trigger component 13 form rear end side sealing gasket engagement portion 13a and forward end sealing gasket engagement portion 13b.The rear end side sealing gasket 12 of the ring-type with undulatory pars contractilis 12a is installed between the large-diameter portion 11a of rear end side sealing gasket engagement portion 13a and inboard cylindrical shell 11.The forward end sealing gasket 14 of the ring-type that is formed with a plurality of crease-like 14a is installed between the minor diameter 11b of forward end sealing gasket engagement portion 13b and above-mentioned inboard cylindrical shell 11 on the other hand.Rear end side sealing gasket and forward end sealing gasket are all formed by rubber, resin etc., when connecting formpiston pipe joint 50, prevent that fluid from leaking into the outside from the stream 3a of former pipe joint 1 and the stream 54 of formpiston pipe joint 50.And, between an end face of forward end sealing gasket 14 and trigger component 13, leaf spring 20 is set.
Described leaf spring 20 does not deform under state shown in Figure 2, remains on like a cork between trigger component 13 and the forward end sealing gasket 14.
Under the state that does not insert formpiston pipe joint 50, because the maintenance ball 9 that the parts 13 that are triggered are shifted the radial outside position onto engage with engagement groove 6c, thereby the moving sleeve 6 that is provided in the outer circumferential side of maintenance tins 4 can not carry out sliding action.And, between moving sleeve 6 and lock operation are with sleeve 7, setting and be used for applying the helical spring 30 that makes its elastic force that leaves mutually, and lock operation can not carry out sliding action at axial direction with sleeve 7 and moving sleeve 6 butts and by the periphery stepped part butt of left part and joint body 2.
Enclose 15 keeping setting between tube 4 and the moving sleeve 6 by helical spring 31 (right-hand) card claw stop pushing of applying elastic force forwards.This card claw stop pushing circle 15 can keep tube 4 and moving sleeve 6 to slide relatively, and under the state of Fig. 2, the elastic force that is applied by helical spring 31 is pressed to the engaging stepped part 6d that forms on the inner peripheral surface of moving sleeve 6.Formed the hooking part 6b that only encloses the inclined plane shape of 5 butts with card in the right part of moving sleeve 6.
As shown in Figure 3, have the upside card claw stop 16 and the downside card claw stop 17 that are entrenched in gap among upper-side hole 4b and the lower-side hole 4c and can move to the position shown in the dotted line.And when moving to radially inner side, only female thread portion is projected into radially inner side from the inner peripheral surface that keeps tube 4.In the present embodiment, upside card claw stop 16 and downside card the claw stop 17 only shape of female thread portion are different, thereby also it can be set respectively on the contrary.
Shown in Fig. 4 a, Fig. 4 b, leaf spring 20 forms a plurality of arms 23 in rear end (left end) the edge portion of the hub cylindraceous portion 21 that forms axis hole 25, and portion forms circular hooking part 22 at front end (right-hand member) edge.Leaf spring 20 can be made by sheet metal etc. is carried out punch process etc.
According to Fig. 2 and Fig. 5, the action when inserting formpiston pipe joint 50 is described.
When pushing formpiston pipe joint 50, the pars contractilis 12a that the rear end bullet is sent out mechanism 10 and rear end side sealing gasket 12 shrinks, and forward end sealing gasket 14, leaf spring 20, trigger component 13, inboard cylindrical shell 11 rearward integratedly (left) slide.The elasticity coefficient of leaf spring 20 is configured to send out the big of mechanism 10 than rear end bullet, and when carrying out described slip, leaf spring 20 can not deform.And in carrying out described sliding process, upside card claw stop 16 and downside card claw stop 17 can move to radial outside, thereby can not hinder the insertion of formpiston pipe joint 50.
Fig. 5 represents the state that formpiston pipe joint 50 is being connected with former pipe joint 1.
By the action of pushing formpiston pipe joint 50, when trigger component 13 being slided into make the position of inner wall part 2a butt of its rear end side sealing pad engagement portion 13a and joint body 2, maintenance ball 9 is fitted in the dump tank 35 of this trigger component 13.Thus, moving sleeve 6 is opened, and forwards slides under the elastic force effect that card claw stop pushing circle 15 helical springs 31 that applying elastic force are applied.
End at the radial outside of upside card claw stop 16 and downside card claw stop 17 forms inclined plane part 16a and inclined plane part 17a.On the other hand, the sliding action that the pushing inclined-plane 15a of formation and described inclined plane part 16a and inclined plane part 17a butt on card claw stop pushing circle 15, above-mentioned upside card claw stop 16 and downside card claw stop 17 are accompanied by card claw stop pushing circle 15 is urged by above-mentioned pushing inclined-plane 15a radius vector is inwardly square.Under the female thread portion on the inner peripheral surface that is formed on upside card claw stop 16 and downside card claw stop 17 and state that the outer screw section 52 of formpiston pipe joint 50 engages fully, as shown in Figure 5, card claw stop pushing circle 15 is in the radial outside position of upside card claw stop 16 and downside card claw stop 17, has stoped these upside card claw stops 16 and downside card claw stop 17 moving to radial outside.
Under the state of Fig. 5, rear end side sealing gasket 12 is folded owing to its contraction flow region 12a, thereby increased the pushing force of joint body to internal face 2b, no matter pipeline is being applied under the situation of malleation, still under the situation that pipeline is applied negative pressure, can bring into play reliable sealing function.
In addition, under the state of Fig. 5, although owing to make that in the distortion on the axial direction gap 36 between the forward end sealing gasket engagement portion 13b of forward end sealing gasket 14 and trigger component 13 is narrow in some degree stenosis, but because almost not distortion of leaf spring 20, so the gap 37 that rib 14b forms does not change.And, between front-end face that keeps tube 4 and formpiston pipe joint 50, set pushing surplus 38.
Fig. 5 represents the formpiston pipe joint is pushed in the former pipe joint until the state that keeps ball 9 to be fitted to the position in the dump tank 35 (promptly, state with formpiston pipe joint pushing established amount), show the state that upside card claw stop 16 that trim ring 15 pushing and downside card claw stop 17 and the outer screw section 52 of these formpiston pipe joints 50 engage fully that is pushed.But, for example being offset from illustrated position in the position of the sense of rotation of formpiston pipe joint 50 under 180 ° the situation, female thread portion can not engage well with outer screw section.Use Fig. 6 a, Fig. 6 b that its snap-fit relationship is described.
In Fig. 5, when formpiston pipe joint 50 is pushed established amount, shown in Fig. 6 a like that, the state that the female thread portion that shows upside card claw stop 16 and outer screw section 52 engage fully.But even formpiston pipe joint 50 is being pushed under the situation of same established amount, like that, the summit of the worm tooth 16b of female thread portion also can not engage with the summit butt of the worm tooth 52a of outer screw section 52 sometimes shown in Fig. 6 b.This also takes place between downside card claw stop 17 and outer screw section 52 simultaneously.Shown under the non-fastening state, when formpiston pipe joint 50 slides to the direction of extracting, become the state that the female thread portion of upside card claw stop 16 engages with outer screw section 52.But under this state, the pushing force that is applied on rear end side sealing gasket 12 and the forward end sealing gasket 14 reduces slightly, might reduce sealability.
Even Fig. 7 shows formpiston pipe joint 50 is being inserted with respect to former pipe joint 1 under the state as shown in Figure 5 of established amount, when above-mentioned female thread portion and outer screw section become state shown in Fig. 6 a, the state that formpiston pipe joint 50 is further pushed.
That is, as mentioned above, under the state of the Fig. 5 that formpiston pipe joint 50 is inserted established amount with respect to former pipe joint 1, residual pushing surplus 38 (Fig. 5) can further push the formpiston pipe joint between front-end face that keeps tube 4 and formpiston pipe joint 50.At this moment, trigger component 13 is held ball 9 and is engaging, and can not carry out displacement at axial direction.Therefore, at first formpiston pipe joint 50 is forced into, makes gap 36 (Fig. 5) disappear while compress forward end sealing gasket 14.When further pushing formpiston pipe joint 50, resiliently deformables take place in leaf spring 20, and formpiston pipe joint 50 Backwards.Between such moving period of formpiston pipe joint, when outer screw section becomes the position that engages with female thread portion, upside card claw stop 16 and downside card claw stop 17 are moved to radially inner side in the effect of card claw stop pushing circle 15, outer screw section and female thread portion are chimeric, thus formpiston pipe joint 50 are connected with former pipe joint 1.
Pushing surplus 38 is configured to the amount of about 1 spiral shell square of the worm tooth of outer screw section 52 (or female thread portion), therefore, before pushing surplus 38 all is pushed into, must have the position of outer screw section and female thread portion engaging.The pushing force that is applied on rear end side sealing gasket 12 and the forward end sealing gasket 14 is decided by the insertion amount of formpiston pipe joint 50, therefore the pushing force that is applied on rear end side sealing gasket 12 and the forward end sealing gasket 14 can positively not seal less than the resulting pushing force during by afore mentioned rules amount insertion former pipe joint the formpiston pipe joint yet.
On the other hand, in the present embodiment, crease-like 14a of forward end sealing gasket 14 is formed and makes its distortion quantitative change big, therefore, even also can obtain sufficient sealing under outer screw section and the situation that female thread portion engages beginning from afore mentioned rules insertion amount to make at the enterprising line displacement of the direction that formpiston pipe joint 50 is extracted.
Fig. 8 is the profile of expression state that former pipe joint 1 is being connected with formpiston pipe joint 50.Formpiston pipe joint 50 is when connecting, and moving sleeve 6 is displaced to than position shown in Figure 2 more forward distolateral (right-hand), and therefore, lock operation can move to the right-hand of position shown in Figure 1 with sleeve 7.Therefore, with described lock operation with sleeve 7 after right-hand moving, rotate this lock operation when making card with sleeve 7 only ball 8 being positioned at position shown in Figure 8, stoped the slip of moving sleeve 6 to left, stoped of the disengaging of formpiston pipe joint from the former pipe joint.
Though moving sleeve 6 and card claw stop pushing circle 15 can be made the parts of one, but in the present embodiment, moving sleeve 6 and card claw stop pushing circle 15 (with reference to Fig. 7) are made into independent parts, therefore, can under the state of holding moving sleeve 6, carry out the connection of formpiston pipe joint 50, thus easy to use.
Shape, the material of above-mentioned rear end side sealing gasket and forward end sealing gasket, rear end side elastic mechanism, leaf spring, trigger component and inboard cylindrical shell etc. are not limited to above-mentioned mode of execution, can carry out many variations.For example, the radical of the arm of forward end elastic mechanism, shape can change arbitrarily according to desired elastic force.And the card claw stop that engages with the outer screw section of formpiston pipe joint, shape, the quantity of carrying out the hole of Spielpassung with this card claw stop also can be carried out various changes, for example also can use in week upwards one to be divided into four and the card claw stop of formation etc.
