Described securing bolt is arranged on cover shell by screw thread is adjustable, and runs through cover shell, and the end of described securing bolt is resisted against on the tube wall of two pipe ends simultaneously, and described securing bolt is at least two.
Described cover shell is provided with for observing projection and the porthole of two pipeline connection states, and described projection runs through this porthole.
Further, the internal diameter of described cover shell equals the external diameter of two pipelines, and the inwall of described cover shell is provided with some anti-slip tanks for preventing pipeline from sliding.
Further, described projection is rectangular parallelepiped projection.
Further, described securing bolt end is integrally formed with the arc block that matches with two outer diameter tube, and described arc block is arc with the contact surface of interior axle, and the radius of this arc is not less than interior axle radius.
Further, described interior axle adopts hollow structure, and the external diameter of described interior axle equals the internal diameter of two pipelines.
Further, being equipped with sealing-ring between described interior axle and two pipelines, the outer wall of described interior axle is provided with the sealing groove for installing sealing circle.
Further, it is provided with chamfering between the two ends of described interior axle and the outer wall of interior axle.
Further, described chamfering is 45 ��
Compared to prior art, the utility model has following useful effect: the security adding pipeline use procedure; And can dismantle, it is to increase the convenience of maintenance process.

Embodiment
For achieving the above object of the present utility model, the utility model have employed following technical scheme:
For a junctor for pipeline docking, comprise be sleeved on outside two pipelines 1 cover shell 2, be arranged on cover shell 2 for two pipelines 1 are coaxially fixed in cover shell 2 securing bolt 3, interior axle 4 in the pipeline 1 that is arranged on two.
The end that described interior axle 4 is provided with projection 41, two pipelines 1 for preventing two pipelines 1 from relatively rotating is equipped with the opening 11 matched with this projection 41, and this projection 41 embeds in the opening 11 of two pipelines 1 simultaneously.
Described securing bolt 3 is arranged on cover shell 2 by screw thread is adjustable, and runs through cover shell 2, and the end of described securing bolt 3 is resisted against on the tube wall of two pipeline 1 ends simultaneously, and described securing bolt 3 is at least two. In the present embodiment, it is provided with two securing bolts.
Described cover shell 2 is provided with for observing projection 41 and the porthole 21 of two pipeline 1 connection states, and described projection 41 runs through this porthole 21.
In the present embodiment, described projection 41 is rectangular parallelepiped projection 41. Corresponding, the opening 11 of two pipeline 1 ends matches with this rectangular parallelepiped projection 41.
During installation, loosen securing bolt 3, the two ends of interior axle 4 are respectively charged in two pipelines 1, and make projection 41 embed the opening 11 of two pipelines 1, then tighten securing bolt 3. In junctor of the present utility model, owing to projection 41 runs through porthole 21, make interior axle 4 relatively overlap the rotating angle of shell 2 to be limited, projection 41 only can rotate in porthole 21 with interior axle 4, the opening 11 observing two pipelines 1 in installation process by porthole 21 coordinates situation with projection 41, is more convenient for installing; In addition, this projection 41 also can prevent two pipelines 1 from relatively rotating so that the connection of two pipelines 1 is more firm, and safety performance is better; Wherein, overlap shell 2 and also the end of two pipelines 1 is had provide protection.
A kind of junctor for pipeline docking of the present utility model, adds the security of pipeline use procedure; And can dismantle, it is to increase the convenience of maintenance process.
As the improvement of such scheme, the internal diameter of described cover shell 2 equals the external diameter of two pipelines 1, and the inwall of described cover shell 2 is provided with some anti-slip tanks 22 for preventing pipeline 1 from sliding. Pipeline 1 can be made fixing more reliable, now, not easily relatively rotate between cover shell 2 and two pipelines 1, so that not easily relatively rotate between securing bolt and two pipelines, reduce the abrasion of pipeline.
As the improvement of such scheme, described securing bolt 3 end is integrally formed with the arc block 31 that matches with two pipeline 1 external diameters, and described arc block 31 is arc 311 with the contact surface of interior axle 4, and the radius of this arc 311 is not less than interior axle 4 radius.This arc block 31 can increase the contact surface between securing bolt and two pipelines, reduces pressure, reduces the infringement to pipeline.
As the improvement of such scheme, described interior axle 4 adopts hollow structure, and the external diameter of described interior axle 4 equals the internal diameter of two pipelines 1. The interior axle of this hollow structure can realize fluid transport so that the scope of application of junctor of the present utility model is wider.
In the present embodiment, being equipped with sealing-ring 42 between described interior axle 4 and two pipelines 1, the outer wall of described interior axle 4 is provided with the sealing groove 43 for installing sealing circle 42, and the sealing property transported in flow liquid process can be made better.
In the present embodiment, between the two ends of described interior axle and the outer wall of interior axle, it is provided with chamfering 44. Concrete, this chamfering 44 is for reducing assembly difficulty when interior axle 4 assembles for 45 �� of these chamferings 44.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, and not departing from objective and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
