ABSTRACT:
The invention is used for locking and sealing railway wagons and containers, warehouses, shops, stalls etc. The invention makes it possible to increase the locking reliability by means of a small, easy-touse device. The inventive device comprises a part of wire rope whose one end passes through a body and is fixed with the aid of two spring-loaded rollers during a locking operation. The external side surface of each roller has a spiral or dentate shape and is formed by successively disposed collars and annular grooves. Each roller together with the spring thereof and a pusher is arranged inside the body on a separate mounting seat which is embodied in the form of a longitudinal slot whose width corresponds to the diameter of the roller. The slots are disposed at an angle with respect to each other and the longitudinal axis of the end-to-end channel of the body. The slots are provided with end cylindrical stop surfaces which are oriented towards the input hole of the body and offset with respect to each other. Several variants for the arrangement of the rollers inside the body and with respect to each other are also disclosed.
