A kind of pipe joint structure-improved includes: a connecting head, and the one end is provided with a screw section, and terminal the extension in addition in this screw section is provided with a belled part, and the diameter of this belled part is less than the diameter of this screw section, and this belled part is inserted in the body; One inner ring sleeve, it is outside to be sheathed on this body, and this inner ring sleeve is provided with a plurality of flutings; One hold-doun nut is sheathed on this inner ring sleeve, and this hold-doun nut one end is provided with an opening end and the other end is provided with necking end, and this opening end screw section of being provided with internal thread and this connecting head locks together again, then this inner ring sleeve of the corresponding extruding of this necking end packing.
This hold-doun nut is convergent by opening end towards necking end.
This connecting head the other end is provided with a coupling nut.
This body is an oil pipe.
This belled part is provided with outside thread.
This body is provided with internal thread.
This body is provided with outside thread, and this inner ring sleeve also to be provided with internal thread corresponding with the outside thread of this body.
The utility model hold-doun nut can use any instrument (for example: spanner) carry out sealed, and can push packing to inner ring sleeve by hold-doun nut, relatively push the position that the screw section of packing connecting head is connected with body by inner ring sleeve again, make connecting head and body be able to tight the connection.

Embodiment
For the effect that makes the convenient simple and direct understanding further feature content of the present utility model of auditor and advantage and reach can more manifest, hereby the utility model is cooperated accompanying drawing, be described in detail feature of the present utility model and advantage, following embodiment further describes viewpoint of the present utility model, but non-to limit anyways category of the present utility model.
Please consult first shown in Fig. 1,2, the utility model discloses a kind of pipe joint structure-improved, espespecially be connected with a default body 4, and body 4 is provided with internal thread 41 and outside thread 42, pipe joint of the present utility model includes a connecting head 1, an inner ring sleeve 2 and a hold-doun nut 3.
Connecting head 1 one end is provided with coupling nut 11 and the other end is provided with screw section 12, and screw section 12 ends of connecting head 1 have extended a belled part 13 in addition, and the diameter of belled part 13 is less than the diameter of this screw section 12, and belled part 13 can be inserted within the body 4.
