摘要： An apparatus for releasably connecting a bonnet to a body of a blowout preventer includes a latch plate that is mounted to the body of the blowout preventer. The latch plate has a plate profile on an outer surface of the latch plate. A clamping assembly extends through the bonnet and includes a clamping screw releasably secured to, and extending through the bonnet. A latch key is located at an inner end of the clamping screw, the latch key having a key profile shaped to mate with the plate profile and to resist relative movement between the latch key and the latch plate. The clamping assembly is moveable between an engaged position where the key profile mates with the plate profile, and a released position where the key profile is spaced apart from the plate profile.
