It is enclosed in both ends equipped with screw thread, the oil pipe end connects with the connecting tube end thread；
The both ends periphery of the connecting tube is equipped with through-hole, and the periphery of the oil pipe is equipped with the groove of annular
Further include clip, enclose in the clip equipped with limited block, the limited block can be by described in through-hole insertion
In the groove of oil pipe.
Preferably, the through-hole is in bar shaped, and the through-hole is symmetrically arranged with the two sides of the connecting tube；The limited block is in circle
Arcuation is bonded with the periphery of the oil pipe.
Preferably, the clip includes the first clip and the second clip of semi-circular shape；First clip and described
The medial surface of two clips is equipped with the limited block；The both ends of first clip and second clip are equipped with engaging lug,
The engaging lug is connected by bolt.
Preferably, the both ends periphery of the connecting tube also is provided with the groove of annular, and the through-hole is set to the connecting tube
In groove.
Preferably, it is integrated between the engaging lug, the limited block and first clip, second clip
Type.
The utility model has the beneficial effects that
The both ends periphery of the utility model connecting tube is equipped with through-hole, and the periphery of oil pipe is equipped with the groove of annular, the limit of clip
Position block is embedded in the groove of oil pipe by through-hole, the connection strong degree being greatly improved between oil pipe and connecting tube, and then is conducive to
Improve the airtightness of connection.
Detailed description of the invention
Attached drawing is used to provide a further understanding of the present invention, and constitutes part of specification, practical with this
Novel embodiment is used to explain the utility model together, does not constitute limitations of the present invention.In the accompanying drawings:
Fig. 1 is the utility model main view；
Fig. 2 is the utility model structure chart；
In the figure, it is marked as 1, connecting tube；2, oil pipe；3, through-hole；4, clip；41, the first clip；42, the second clip；5, it limits
Position block.
Specific embodiment
As depicted in figs. 1 and 2, a kind of tubing coupling, including oil pipe 2 and connecting tube 1, the both ends periphery of the oil pipe 2 are set
There is screw thread；It encloses in the both ends of the connecting tube 1 equipped with screw thread, 2 end of oil pipe connects with 1 end thread of connecting tube；
The both ends periphery of the connecting tube 1 is equipped with through-hole 3, and through-hole 3 is elongated, and the periphery of the oil pipe 2 is equipped with the groove of annular, oil
The groove of pipe and screw thread keep suitable distance, and about 5 centimetres, the screw thread enclosed in the both ends of connecting tube 1 is apart from about 5 lis of port
Rice avoids the normal sealing for influencing screw thread and connection；The through-hole 3 is symmetrically arranged with the two sides of the connecting tube 1；Two sides are equipped with logical
The strong degree of connection can be improved in hole 3；Further include clip 4, encloses in the clip 4 equipped with limited block 5, the limited block 5 can lead to
The through-hole 3 is crossed to be embedded in the groove of the oil pipe 2；Fastening effect is played by clip 4, passes through the recessed of limited block 5 and oil pipe 2
It is acted between slot, limit fastener effect can be played, and then improve the strong degree of connection；Annular groove is convenient for the insertion of limited block 5, institute
It states limited block 5 and is bonded in arc-shaped with the periphery of the oil pipe 2, the firm of connection so can be improved；The clip 4 includes semicircle
The first clip 41 and the second clip 42 of shape；The medial surface of first clip 41 and second clip 42 is equipped with described
Limited block 5；The both ends of first clip 41 and second clip 42 are equipped with engaging lug, and the engaging lug passes through bolt phase
It connects；Separate structure by the first clip 41 and the second clip 42 is easy to disassemble；
Wherein, the both ends periphery of the connecting tube 3 also is provided with the groove of annular, and the through-hole 3 is set to the connecting tube 3
In groove；By the way that the first clip 41 and the second clip 42 can be embedded in the groove of connecting tube 3, the strong degree of clip 4 can be improved；
It is integrally formed between the engaging lug, the limited block 5 and first clip 41, second clip 42, can so mention
The intensity and service life of high device.
The working method of the utility model:
As depicted in figs. 1 and 2, by oil pipe 2 and 1 end of connecting tube by threaded engagement, the groove of oil pipe 2 is torqued-up to pair
Neat through-hole 3；First clip 41 and the second clip 42 are trapped among in the periphery of oil pipe 2, and make the first clip 41 and the second clip 42
It is embedded in the groove of connecting tube 1, and limited block 5 is run through into through-hole 3, be embedded in the groove of oil pipe 2；Finally by 41 He of the first clip
The engaging lug at the both ends of the second clip 42 is connected by bolt.
The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, although referring to before
Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
