DEVICE FOR LOCKING ARTICLE PARTS DETACHABLE DURING OPERATION Russian patent published in 2007 - IPC F16B1/00 F16B2/06 B64G1/64 F42B15/36 

FIELD: mechanical engineering.

SUBSTANCE: device comprises cylindrical housing, member provided with locking units, and ring stop. The cylindrical housing is provided with the ring flange spring-loaded with respect to the ring stop of the member and can cooperate with the latter when the device is set in operation. The member receive axially aligned rod made of a threaded rod and cylindrical rod spring-loaded with respect to the ring stop. The rod is provided with a shaped projection from the side opposite to its threaded rod. The cylindrical rod is provided with a shaped socket for cooperation with the shaped projection of the rod and has shaped shank for wrench. The locking members can cooperate with the inner side of the cylindrical housing and with the rod. The device is provided with the pyrotechnic drive for setting the cylindrical housing in axial motion with respect to the member, casing, and means for fastening the device to the article part to be detached. The casing embraces the cylindrical housing and the member and is rigidly connected with its face flange. The outer side of the casing is provided with a boss having threaded socket for receiving the pyrotechnic pressure source. The inner side of the casing is provided with the collar and ring groove. The groove is connected with the threaded socket. The pyrotechnic drive is defined by ring flange of the cylindrical housing, ring collar, and the groove in the casing and pyrotechnic pressure source.

EFFECT: improved structure and expanded functional capabilities.
