Described spring block piece includes the spring that one end is fixed on buckling groove cell wall, the perpendicular catch being fixed on the spring other end, and is vertically set on the strut rail sheet on perpendicular catch top；Being provided with shifting chute on the two side that described buckling groove is relative, the two ends of this strut rail sheet lay respectively in two shifting chutes.
The process that implements of the present utility model is:
Connecting tube body is rotated on one of them petroleum pipeline, until exposing petroleum pipeline road junction, then another petroleum pipeline road junction is directed at this petroleum pipeline road junction, then this connecting tube body is reversely rotated, until stopping the rotation when being respectively positioned in connecting tube body in two petroleum pipeline road junctions, finally rotate this latch closure, make annular fastener be tightly fixed on petroleum pipeline, be then fixed in buckling groove by the free end of connecting rod.
By above-mentioned setting, can effectively realize threadeding of petroleum pipeline and connecting tube body without rotating petroleum pipeline, the installation of connecting tube can be realized afterwards well.Which makes the installation connection easier, between connecting tube and petroleum pipeline of connecting tube more stable.
And the direction screwed due to two latch closures is relative, thereby through the setting of connecting rod, can effectively prevent loosening of latch closure, reach the effect being preferably stably connected with.The effect of spring block piece can increase the applicable distance between two latch closures, makes operation easier.
Further, described annular fastener is be arranged in parallel by two or more and is fixed on the anchorage bar of connecting tube body end after circular array, the outer combination screw thread composition formed after being arranged on all anchorage bars and combining；It is provided with inside described latch closure and outer combination screw thread.
In order to be able to reach the fastening effect of optimum, described anchorage bar is string configuration, and the cross section of this anchorage bar is cambered surface trapezium structure.The pad that the direction thickness along fixing end is gradually reduced it is provided with on described anchorage bar.
As optimally set-up mode, described spring block piece includes the spring that one end is fixed on buckling groove cell wall, and the catch composition being fixed on the spring other end.
The card being hinged on latch closure to effectively prevent the upper surface of described buckling groove to be provided with.
This utility model compared with prior art, has such advantages as and beneficial effect:
1, this utility model can effectively realize threadeding of petroleum pipeline and connecting tube body without rotating petroleum pipeline, can realize the installation of connecting tube afterwards well；
2, this utility model setting by connecting rod, can effectively prevent loosening of latch closure, reach the effect being preferably stably connected with.The effect of spring block piece can increase the applicable distance between two latch closures, and the installation connection easier, between connecting tube and petroleum pipeline making connecting tube is more stable；
3, this utility model simple in construction, cost performance height, effect is notable, is especially suitable for popularization and application.
