Embodiment
With reference to above accompanying drawing, coupling gear according to the present invention is intended to be used for the element of an end of pipe 2 with the loop of conveyance fluid under pressure connect.Element (do not add and describe) can be a part of carrying or receive fluid herein, as the other end of similar objects such as pipe pump, container.
Referring to Fig. 1, coupling gear comprises a body 4, and body 4 comprises a part 6 that connecting element is used and connects the tubulose socket 8 that the end of pipe 2 is used.For example, attachment portion 6 can be equipped with a tubulose socket identical with tubulose socket 8 or be the part of connected element.
Tubulose socket 8 is fixed on the attachment portion 6, and the end that its free end 10 is used to admit pipe 2.In body 4, be provided with a ring-type convex shoulder 12, be used for against the end of living pipe 2.
Tubulose socket 8 comprises an inner shell 14, and the diameter of this housing is bigger than the external diameter of the end of the pipe 2 that extends from free end, and joins in ring-type convex shoulder 16 and attachment portion 6.Be disposed with housing 14 from convex shoulder 16, O shape circle 18, packing ring 20 grasps circle 22, and guide 24.
Grasp circle 22 and be a kind of known type.It comprises the collar of a peripheral annular and towards the plurality of teeth that is radial extension of collar inside and axioversion.The method of seal ring 18, packing ring 20 being installed and grasping circle is that those skilled in the art are known, and the method is corresponding with the conventional mounting of a coupling gear that is commonly referred to quick coupling.
The external diameter of the end of the internal diameter of guide 24 and pipe 2 about equally.Grasp circle 22 and support by guide 24 and be resisted against on the packing ring 20, and this guide outside have with the free end that is formed on body 4 on the screw thread 26 of corresponding tapping thread 28 cooperatings.Therefore, guide 24 has to lean against and grasps the opposing backside surface 30 that circle one on 22 are positive and be positioned at free end 10 1 sides of body 4.Therefore, guide also has the function that fixedly grasps circle 22 except that the function with end of guiding pipe 2 in tubulose socket 8.The confining force of the end of pipe 2 is provided by the tooth that grasps circle 4, promptly when the end of pipe is introduced into tubulose socket 8, these teeth produce bending by them towards the inner inclination of body 4, if and apply a pulling force with the direction of separating in the end of this pipe 2, these teeth are supported on the end of pipe, thereby prevent the end separating of pipe 2.
Yet it can separate circle 31 from the ends that body 4 takes out pipes 2 by use, and this separates circle and is described in the enforcement of method of the present invention hereinafter.
Fig. 3 to Fig. 5 has illustrated first kind of variation according to separation method of the present invention, has used a kind of coupling gear depicted in figure 1 and a kind of circle 31 of separating depicted in figure 2 in the method.
This kind separated the form that circle 31 is a kind of trip ring, can make with the composite of for example injection moulding or turning.It comprises an external diameter trip ring 32 about equally of an external diameter and packing ring 20.The semicircular ring 34 that this kind trip ring 32 has two sectional shapes on its inner face be isosceles triangle.When the summit relative with the base was connected with trip ring 32, the base of isosceles triangle was used for the outer surface near the end of pipe 2, and this trip ring 32 only extends axially on a side of the vertex of a triangle relative with the triangle base.Therefore, on relative opposite side, each semi-ring 34 has one and is used for and the plush copper (stud) 36 that grasps circle 22 tooth cooperating.This plush copper 36 is radially outstanding from trip ring 32.
So for example with the method described in hereinafter, the end of pipe 2 is separated.Fig. 1 shows the end at the pipe 2 of the inside of connecting piece link position.When supporting in the housing of guide 24 at it when grasping circle, the tooth that grasps circle 22 nip pipe this end outer surface and maintain this end.
In the time will separating pipe 2, at first to from tubulose socket 8, outward winding and take out guide 24.In order to make it be convenient to outward winding, the back side 30 of guide 24 is provided with some notches 38.Then, just can use a kind of proper tools (not shown), instrument be fitted into make guide 24 rotations in these notches.In case guide 24 is outwarded winding and taking-up from tubulose socket 8, will separate circle 36 by this way and place on the end of pipe 2, promptly plush copper 36 places the same side (Fig. 3) of body 4.Separate circle owing to use elastic material to manufacture, therefore separate circle 31 and just can be cooperated easily.Then, guide 24 is axially pushed to body 4, and promotes to separate circle 31 with it.Then the screw thread 26 of guide 24 just can match with corresponding tapping thread 28.Use the identical instrument of using when outwarding winding guide 24, guide just is rotated on body 4.Therefore, plush copper 36 makes that the tooth that grasps circle is crooked in such a way, i.e. these teeth outer surface of pipe 2 of no longer nipping, thus allow the end separating of pipe 2 but can not cause any infringement.
In case the end of pipe 2 is removed, all requirements are to take out to separate circle 31 and ressemble guide 24, it is screwed in the tapping thread 28, thereby acquisition can connect the coupling gear of the other end of a pipe, perhaps connect the end of a pipe that has used.
Fig. 6 and Fig. 7 show a kind of variation of the embodiment of above-mentioned coupling gear.In these diagrammatic sketch, components identical is represented with identical label.
Second kind of embodiment and first kind of embodiment's difference is, when separating circle 31 when being introduced into tubulose socket 8, separates circle 31 and is fixed on guide 24.Like this, during the end of dismounting pipe 2, separate circle 31 and remain on the guide 24, and in first kind of embodiment, exist hidden danger here,, separate circle and will stay in the housing 14 of tubulose socket 8 in case the end of pipe 2 is removed.
In this embodiment's variation, to separate circle 31 and have a ring-type fin 40 in a side relative with pin 36, this stiffening rib extends axially and has an outer surface of some conical tapping slightly.Guide 24 itself has an annular recess 42 that has accordingly a conical tapping surface equally, when guide 24 will be separated circle 31 when being pushed into shell 14 in, feasiblely allows to be fixed.
Compare with the above-mentioned method of separating, unique variation is, before carrying out separation, separates circle 31 and is pressed abd fixed on the guide 24.After separating, separate circle 31 and remain fixed on the guide 24, till circle is separated in operator's taking-up.
The present invention is not limited only to abovely state embodiment with what the mode of non-limitative example was chatted, and on the contrary, it can also make various conversion in the scope of claims.
