Abstract

The invention discloses a connecting and releasing device utilizing a separation nut. The connecting and releasing device is used for connecting and releasing two detached bodies and comprises the separation nut, a gasket, a cylindrical spring, a lock nut, a collecting box and an anti-shear taper sleeve. The separation nut comprises a screw stem, and the collecting box is arranged above the separation nut. The anti-shear taper sleeve is fixedly mounted on an abutting frame of a support chamber between the two detached bodies. The screw stem penetrates the two detached bodies, the gasket and the cylindrical spring sequentially and is locked by the lock screw, so that the two detached bodies are connected. By means of separation of the separation nut, the separated screw stem and the lock nut are pushed into the collecting box by the cylindrical spring, so that the two detached bodies are released without any spatial redundancy. Reliability in separation of the two detached bodies is guaranteed by spherical-surface matching between the lock nut and the gasket.
