FAST CONNECTION FOR PIPES OF WELL TUBES Russian patent published in 2017 - IPC E21B17/03 E21B17/07 

FIELD: oil and gas industry.

SUBSTANCE: connector assembly comprises an upper adapter comprising a housing of the upper adapter, a lower adapter comprising a housing of the lower adapter. The body of the upper adapter includes a snap-in sleeve and a screw sleeve located at a distance from the snap-fit sleeve in the axial direction. The screw bush comprises a plurality of axially extending torsion elements and a corresponding torsion bar formed in each axially extending torsion member. The case of the lower adapter is adapted to receive the body of the upper adapter and provides several threads of coupling by means of a latch formed on the inner surface of the case of the lower adapter and the profile of the screw bush. In this case, the threads of the coupling by means of the latch are adapted to cooperate with the snap-fit sleeve and the profile of the helical sleeve containing one or more longitudinal grooves formed in the lower adapter body and configured to receive the torsion ridges into itself. When placing the upper adapter in the lower adapter, compression and tension loads can be applied between the upper and lower adapters. Moreover, when locating the torsion bars in the longitudinal grooves, the torque can be applied between the upper and lower adapters in at least one angular direction.

EFFECT: providing resistance to axial and torsional loads.
