Embodiment
The technique effect of the design of the present invention, concrete structure and generation is carried out below with reference to embodiment and accompanying drawing clear
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright a part of embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
The other embodiment obtained on the premise of creative work, belongs to the scope of protection of the invention.In addition, be previously mentioned in text
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.
As illustrated in fig. 1 and 2, a kind of locking stereoplasm tube connecting parts, including connecting head 1 certainly with nipple, described to plug into
First 1 includes outer locking set 11, inner connection tube 12, sealing ring 13 and movable snap ring 14, and the front end of the connecting head 1 is inserted terminal
Mouthful, the outer locking set 11 has the first inwall 111, and first inwall 111 is adapted and solid with the outer wall of inner connection tube 12
Fixed connection, the inner connection tube 12 is provided with the groove being embedded in for sealing ring 13, it is characterised in that：It is described it is outer locking set 11 it is interior
Wall is additionally provided with annular groove, and the annular groove includes preceding snap ring retaining wall 112, rear snap ring retaining wall 115 and at least two-stage internal diameter is different
Vallecular cavity, respectively including first order vallecular cavity and second level vallecular cavity, the first order vallecular cavity have the first bottom wall 113, described second
Level vallecular cavity have the second bottom wall 114, the first order vallecular cavity than second level vallecular cavity closer to grafting port, the preceding snap ring retaining wall
112 are connected with the front end of the first bottom wall 113, and the rear snap ring retaining wall 115 is connected with the rear end of the second bottom wall 114, the activity
Snap ring 14 is placed in annular groove, and the movable snap ring 14 can radially be stretched, change of contracting, the inwall of the second bottom wall 114 and first
111 distance is H, and the distance of the inwall 111 of the first bottom wall 113 and first is h, is met：H ＞ h.
