Limiting slot is connected, is equipped with antitorque slotting ring on the outside of the limiting slot, the inner cavity of the female connector is successively arranged end face mating surface, radial direction
Mating surface, the female connector outside are additionally provided with grafting block, and the slot with the antitorque slotting ring cooperation is offered on the grafting block.
As a kind of improvement of the utility model, the antitorque slotting ring and the pin end are integrally formed, the grafting block
It is integrally formed with the female connector.
As a kind of improvement of the utility model, the identical screw thread of diameter is additionally provided on the antitorque slotting ring and grafting block
Hole.
As a kind of improvement of the utility model, the end cross-sectional of the antitorque slotting ring and slot is semicircle.
As a kind of improvement of the utility model, the jump-ring slot is provided with opening circlip, and the sealant ring recess is built-in
There is sealing rubber ring.
The utility model has the advantages that
1, a kind of riser joints for marine drilling described in the utility model, by pin end, female connector
The antitorque slotting ring and slot of cooperation grafting is respectively set, enhances the anti-twisting property of riser joints, extends at riser joints
Effectively use duration.
2, in order to improve the stability of entire joint structure, antitorque slotting ring is an integral molding structure with grafting block；
3, the two is fixed by screw again after antitorque slotting ring insertion slot, keeps the connection between male and female connector more steady
Gu the ability for resisting radial torque is stronger.
