摘要： A pressurizable assembly which comprises first and second assemblies. The first assembly has a plurality of cam grooves while the second assembly is size and shaped to intimately receive and mate with the first assembly. The second assembly has a connection member a plurality of radially mounted locking pin mechanisms for interacting with one of the plurality of spaced apart cam grooves. Axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the cam grooves to an intermediate locking position which locks the second assembly with the first assembly, while a subsequent axial movement of the second assembly, toward and away from the first assembly, causes the plurality of locking pin mechanisms to follow along the plurality of cam grooves and disengage the second assembly from the first assembly.
