CABLE LOCKING DEVICE Russian patent published in 2023 - IPC E05B39/02 F16G11/04 

FIELD: mechanical engineering.

SUBSTANCE: cable locking device includes a housing made with a cylindrical side surface and two flat end surfaces parallel to each other. The passive end of the cable section is placed in a blind channel made in the housing from the side of its cylindrical side surface and is fixed in it, and the free end, when locked, is passed through an inlet hole and an inlet through channel, a recess and an outlet through channel and an outlet hole of the housing. The inlet and the outlet channels are made on the side of the cylindrical side surface of the housing. The recess is made open on the side of one of its flat end surfaces. The free end of the cable section is fixed in the recess by means of two spring-loaded rollers. The input and the output through channels with a recess and the blind channel are located on opposite sides of the diametrical plane of the cylindrical side surface of the housing, parallel to the combined central longitudinal axis of its input and output through channels. The combined central longitudinal axis of the input and the output through channels and the central longitudinal axis of the blind channel are placed at an angle to each other, the apex of which faces the outlet hole. There are four protrusions on the cylindrical side surface of the body, symmetrical in pairs relative to the central axis of the cylindrical side surface of the body. Two protrusions of one pair are directly adjacent to the outlet of the blind channel of the housing and to the inlet of the inlet through channel of the housing and are united by a flat surface tangent to the cylindrical side surface of the housing and located at an angle of 65-75° to the combined central longitudinal axis of the input and the output through channels. Two protrusions of the other pair are located on the cylindrical side surface of the body symmetrically to the first pair of protrusions, and the flat surfaces connecting them, tangent to the cylindrical side surface of the body, are parallel to each other. The device is equipped with a mushroom-shaped pusher, which includes a cylindrical part and an associated cap made in the form of a straight parallelepiped, the length of two opposite larger faces of which corresponds to two diameters of the rollers. The pusher is made with a through hole, the diameter of which corresponds to the diameter of the cable section. The plane of the outer surface of the pusher cap is perpendicular to the combined central axes of the through holes of the pusher, the inlet and the outlet channels of the housing. Between the recess and the through output channel there is a groove of rectangular shape in cross section to accommodate a coiled compression spring, inside of which the cylindrical part of the pusher is located. The length of the groove is at least 2.5 times the diameter of the cylindrical part of the pusher. The outer flat surface of the cap contacts the rollers, pressing them in a position prepared for locking against the side wall of the recess facing the inlet through channel. In the locked position of the device, the reverse flat surface of the cap, on which the end of the spring rests, is placed opposite the side wall of the recess facing the groove and the outlet through channel of the housing.

EFFECT: creation of a reliable, easy-to-manufacture cable locking device, which at the same time has increased resistance to unauthorized criminal opening.
