All connection/annexations, not singly refer to component and directly connect, and refer to be added deduct by adding according to specific implementation situation
Few couple auxiliary, to constitute more excellent draw bail.Each technical characteristic in the invention, in not conflicting conflict
Under the premise of can be with combination of interactions.
Embodiment 1：As illustrated in fig. 1 and 2, a kind of stereoplasm tube overcoat connecting parts, including tubulose connector a1, sealing ring a4,
Movable snap ring a2 and interior insertion pipe a3, the tubulose connector a1 front end have grafting port a11, the sealing ring a4 setting-ins
Annular groove is additionally provided with tubulose connector a1 inwall a12, the inwall a12 of the tubulose connector a1, the annular groove includes
Preceding snap ring retaining wall a13, rear snap ring rib a14 and the different vallecular cavity of two-stage internal diameter, respectively first order vallecular cavity and second level groove
Chamber, the first order vallecular cavity has the first bottom wall a15, and the second level vallecular cavity has the second bottom wall a16, the first order vallecular cavity
Than second level vallecular cavity closer to grafting port a11, the preceding snap ring retaining wall a13 is connected with the first bottom wall a15 front end, it is described after
Snap ring retaining wall a14 is connected with the second bottom wall a16 rear end, and the movable snap ring a2 is placed in annular groove, the interior insertion pipe a3
End be provided with the grafting station that is adapted with tubulose connector a1 internal diameter of external diameter, the front side of the grafting station is provided with groove
A31, the groove a31 formation snap ring locking station, the second bottom wall a16 and inwall a12 distance is H, first bottom
Wall a15 and inwall a12 distance is h, and the depth of the groove a31 is L, and the cross-sectional width of the movable snap ring a2 is d, full
Foot：
H ＞ h；
And, H >=L ＞ d-h.
What the connecting structure of the present embodiment was realized in：
Interior insertion pipe a3 inserts tubulose connector a1 from grafting port a11.The internal diameters of the movable snap ring a2 under normal conditions
Be slightly less than interior insertion pipe a3 external diameter, therefore adapter a3 can be interpolated and promote toward the movement of second level vallecular cavity, when by after snap ring keep off
Deform upon, expand after wall a14 stop, make interior insertion pipe a3 can continue to enter in tubulose connector a1, until active card
Ring a2 is fallen into groove a31 snap ring locking station.When movable snap ring a2 is engaged with groove a31, even if reversely grafting in withdrawing
Pipe a3, the movable snap ring a2 can be towards the movements of first order vallecular cavity, due to first order vallecular cavity in the case where snap ring locks the drive of station
Interior insufficient space is to allow movable snap ring a2 to deviate from out of groove a31, so the interior insertion pipe a3 and tubulose connector a1 is real
Existing self-locking.
Embodiment 2：As shown in Figures 3 and 4, it is with the distinctive points of embodiment 1：
The sealing ring b4 is flush-mounted on inner connection tube b3 outer wall, the tubulose connector b1 include casing head b11 and
Threaded fastener b12, described sleeve pipe head b11 and threaded fastener b12 threaded connections, the annular groove is by casing head b11 and spiral shell
Line locking member b12 splits are constituted.Described sleeve pipe head b11 has internal thread, and the threaded fastener b12 has external screw thread, works as set
After tube head b11 and threaded fastener b12 is tightened, threaded region vacant casing head b11 is the second described bottom wall b13.
The interior insertion pipe b3 also takes the processing modes different from embodiment 1, the end of the interior insertion pipe b3 provided with external diameter with
The grafting station that tubulose connector b1 internal diameter is adapted, the front side of the grafting station is provided with projection b31, the projection b31
Front side form snap ring locking station, snap ring locking station refers to the obtuse angle region that projection b31 partial right sides are formed, institute
State projection b31 and lock the difference in height of station with snap ring for M, the cross-sectional width of the movable snap ring is d, meets H-d >=M ＞ h-d
≥0.Similarly, the interior insertion pipe can also realize that the opening part external diameter of the reducer pipe is larger from locking using reducer pipe,
Then there is the conical surface of dimensional contraction transition, the conical surface is the snap ring locking station of reducer pipe.Described sleeve pipe head b11 and spiral shell
Line locking member b12 can be screwed before interior insertion pipe b3 insertions, also can again be screwed after interior insertion pipe b3 insertions, both can't produce
Raw difference.
Embodiment 3：As shown in Fig. 5~7, the distinctive points of itself and embodiment 2 are：
Described sleeve pipe head c11 has external screw thread, and the threaded fastener c12 has internal thread, the interior insertion pipe c3's
Outer surface is smooth cylinder, and the external diameter of the interior insertion pipe c3 is adapted with tubulose connector c1 internal diameter, the active card
Ring c2 section thickness is that D, cross-sectional width are d, and the width of the second level vallecular cavity is b, is met：
D ＞ b；
And, h ＜ d.
What the connecting structure of the present embodiment was realized in：
The interior insertion pipe c3 is passed through in threaded fastener c12 and movable snap ring c2, plug-in-sleeve head c11, is then screwed
The width of second level vallecular cavity is gradually reduced for b in threaded connection between casing head c11 and threaded fastener c12, screwing operations,
As D ＞ b, second level vallecular cavity can not accommodate elastic circlip c2, so as to force it enter first order vallecular cavity.Yet with h
＜ d so that elastic circlip c2 can be by the diametric compressings of inside insertion pipe c3, as casing head c11 in first order vallecular cavity
After being screwed completely with threaded fastener c12, the elastic circlip c2 is oppressed by casing head c11 and threaded fastener c12 simultaneously,
Finally realize internal insertion pipe c3 locking.
The vallecular cavity quantity of above-mentioned annular groove is not limited only to only two grades, but can possess more series, but totally still
The right relation condition for needing to meet the every algebraically of H, h, d.
The various embodiments described above may also include the portion of plugging into, and the portion of plugging into has at least one port of plugging into, the end of plugging into
Mouth is fixedly connected with the rear end of corresponding tubulose connector.The portion of plugging into is reducing or isometrical bend pipe tools, tee pipe fitting,
One kind in four-way pipe fitting.
The better embodiment to the present invention is illustrated above, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent modifications or replace on the premise of without prejudice to spirit of the invention
Change, these equivalent modifications or replacement are all contained in the application claim limited range.
