Abstract:
1. A flexible locking sealing device comprising a wire rope cut which during a locking operation passes through a channel in a body and is fixed there by several spring-loaded rollers, disposed in mounting seats provided in the body and interacting by side surfaces of the rollers with a side surface of the wire rope cut when locking, the mounting seats are made in the form of two longitudinal slots, disposed on two diametrically opposite sides of a through channel of the body, the slots being able to communicate with a space of the channel and having stop end surfaces offset with respect to each other and to an input hole of the body, both slots are inclined with respect to the through channel of the body and the angles of their inclination are directed towards the input hole of the body, the spring-loaded rollers are disposed in the slots able to rotate and move along the slots when locking and able to come up against the stop end surfaces of the slots by the side surfaces of the rollers when a reverse withdrawal of the wire rope cut from the body takes place; wherein the slot, the stop end surface of which is disposed farther from the input hole of the body, has side surfaces that are made flat, rectilinear and parallel to each other, and wherein the other slot, the stop end surface of which is disposed closer to the input hole of the body, has side surfaces that are made flat and consisting from two parts, so that one part of said other slot, having the stop end surface, is disposed at a greater angle with respect to the through channel of the body than the second part of this slot; the external side surface of each roller has a spiral form or is formed by alternate annular sharpened collars and grooves, the cross section planes of which are parallel to each other and inclined with respect to the longitudinal axis of the roller; besides the device is provided with two pushers each disposed in the slot for the rollers and each pusher interacting on one side with the side surface of the corresponding roller, and on the other side—with the roller spring-loading spring; besides, the device is provided with a controller made in the form of a cylindrical body, one end of which is sharpened.
