FIELD: construction.SUBSTANCE: invention relates to a device comprising a body with a through channel for passage of a rope section and a locking facility spring-loaded by a locking spring, comprising an eccentric, installed on the axis rigidly connected to the body, providing for the possibility of simultaneous interaction of the rope section with the wall of the through channel and the end surface of the eccentric, equipped with teeth. The device is equipped with an additional locking facility identical to the main one, duplicating its operation and installed in one plane with it. The distance between axes of eccentrics of locking facilities is selected as multiple to the pitch of rope winding. Eccentrics are installed on axes with ledges. Locking springs are arranged as cylindrical and are installed along the circumference of the body cavity walls. At the same time the body is arranged in the form of a hollow shell with an insert rigidly connected to each other. Locking agents of the facility are mounted in the insert and equipped with an accessory for their retention in the initial position of the device prepared for locking, every of which is arranged in the form of a mount spring. With one end the mount spring interacts with a ledge arranged on the eccentric above teeth, and with the other end - with a stop arranged in the cavity of the body, at which one end of the closing spring rests at the opposite side, besides, the rigidly of the latter is less than the mount spring. In the closed condition of the device, in case of an attempt of unauthorised action at the eccentric and pulling of the rope section in the direction reverse to closing, the specified ledge serves as the facility to prevent access inside the body via an input hole for manipulations with locking facilities.EFFECT: invention provides for high reliability of locking and high criminal resistance.2 cl, 6 dwg |
