DEVICE TO FIX ARTICLE PARTS DETACHED FROM CASING IN COURSE OF OPERATION Russian patent published in 2018 - IPC B64G1/64 F16B1/00 

FIELD: machine building.

SUBSTANCE: invention relates to the field of mechanical engineering and can be used in the design, for example, of spacecraft with detachable elements. In the device for fixing parts of the product detached during operation from the body, longitudinal stops are inserted that are rigidly connected to the case and evenly located on its inner surface, cylindrical flanges located on the ends of the coupling sleeve, longitudinal ribs rigidly connected to the coupling sleeve. Pyrotechnic drive chambers are formed by the specified longitudinal ribs of the turnbuckle and the longitudinal stops of the housing. Longitudinal ribs coupling made with the possibility of interaction with adjacent longitudinal stops of the cylindrical body when the device is triggered. On the inner surface of the coupling sleeve an annular stop is made with the possibility of interaction with the locking elements during operation of the device. Cylindrical body of the device is made with an annular sealed cavity located in the cylindrical wall of the specified body.

EFFECT: technical result of the invention is to improve the operational characteristics of the device.
