FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in all branches of industry where locking of objects is required by means of length of cable fixed by wedging. Proposed clamping device has length of cable one end of which is preliminarily rigidly fixed in housing, and second free end of cable length is pulled through housing to form loop and is fixed in housing by at least two groups of similar solids of revolution. Said solid of revolution are arranged in seats of spring-loaded holder for engagement with side surface of cable length and with inner conical surface of bushing located in inner of housing. Diameters of solids of revolution in each group are different. Device contains washer arranged inside housing from side of its inlet hole to rotate around cable length. Inner conical surface of bushing designed for engagement with solids of revolution is made stepped. From one end face side, said bushing is rigidly coupled with cover and/or housing, and from other side it is pressed to end face of projection on inner surface of housing to limit longitudinal displacement of washer. Bushing is spring-loaded in housing by conical spring, larger diameter end of spring being pointed to output hole of housing, and smaller diameter other end engages with holder. Inner through hole of holder designed for passing of cable length at locking has screw surface following profile of outer screw of cable length. ^ EFFECT: improved reliability of locking owing to provision of protection against unauthorized opening. ^ 3 cl, 3 dwg |
