COMBINED LOCKING AND SEALING DEVICE (OPTIONS) Russian patent published in 2022 - IPC E05B39/02 

FIELD: locking systems.

SUBSTANCE: invention relates to devices designed for sealing cargo, locking and sealing doors of railway freight cars and containers, tank hatches, steering wheels of hopper cars, etc. A combined locking and sealing device (hereinafter – CLSD) contains a piece of rope (9), one end (20) of which is passive and is fixed in case (1), and second free end (22), when locking, is stretched through a through channel in case (1) and fixed in it by means of a locking mechanism in the form of a threaded nut hole. Passive end (20) of rope (9) fixed in a hole made in case (1) and free end (22) of the piece of rope (9) are provided with tips (15). A piece of metal pipe is used as case (1). Case (1) additionally contains a longitudinal viewing hole for control of a condition of the passive part of rope (9) located on the opposite side of the case relatively to a hole designed for a threaded connection of a locking element. Two metal cylinders of an equal outer diameter are inserted into the case. The first cylinder is pressed into a reduced outer diameter of case (1) between two through channels and is stationary. A boundary of the stationary cylinder borders on the through channel, which is located closer to the viewing hole for control of the condition of the passive part of the rope, without crossing it. The opposite boundary of the stationary cylinder partially overlaps the second through channel. On case (1), a bed is formed by a press between two through channels. The second cylinder is installed with the possibility of movement. A nut is installed inside the case from the side of the hole for the threaded connection of the locking element. The nut does not limit the free movement of the second cylinder, allowing it, in its first extreme position, not to close the second through channel in the case for passage of free end (22) of rope (9) through it, and, in its second extreme position, to contact with its surface with the surface of the stationary cylinder pressed into the case and completely block the through channel for passage of free end (22) of the piece of rope. The nut is clamped inside the case by the press by deformation of case (1) from its outer side to its complete immobility without deformation of its thread. The end of the pipe from the side of the nut installation in it is deformed on the press according to a size of the nut installed in it. Metal pipes (8) are put on the piece of rope (9). One of these pipes is fixed to the passive part of the rope, limiting its fall from case (1) without loss of mobility in the case so that one of its edges coincides with passive end (20) of rope (9). This pipe is located on the opposite side relatively to the bed. The second pipe is located so that its edge coincides with free end (22) of rope (9), forming a tip. Remaining pipes (8) are compressed around rope (9) and are stationary relatively to the body of the rope. A diameter of the through channel in case (1) nearest to the viewing hole is larger than a diameter of rope (9) and smaller than an outer diameter of pipes (8) compressed around it, ensuring the inseparability of rope (9) and case (1). Passive end (20) of rope (9) is movable, but limited in its movement with two pipes (8). In an open state of CLSD, a through channel with a protruding edge of the stationary cylinder pressed into the case is made with the possibility of movement through it of free end (22) of rope (9) with a set of pipes (8) pressed around it and installed on it until an adjustable loop is formed. A size of the through channel, taking into account the protruding edge of the stationary cylinder, is larger than the outer diameter of pipes (8) pressed around the body of rope (9). The loop formed by free end (22) of the piece of the rope is made with the possibility of adjustment due to distances between pipes (8) of the rope and a number of such pipes mounted on rope (9). In a closed state, free end (22) of the rope inside the case of CLSD, with the formed inseparable loop, is closed by the freely moving movable cylinder inside case (1), which, by tightening bolt (13) through the nut in the direction of the stationary cylinder pressed inside the case, is installed at a distance equal to the diameter of the rope, forms a through hole with a size smaller than the diameter of pipes (8) pressed on the piece of rope (9). A bolt head is integrated into transparent plastic cover (10). Locking ribs are applied on the inner side of cover (10), which allow it to rotate relatively to the case of CLSD only in the direction of tightening bolt (13) along thread into case (1) through the body of the nut. Locking ribs interact with plates of blocker (12) made of plastic, mounted on case (1) of CLSD before installing cover (10) on it, so that it is impossible to turn it around the case of CLSD without damage. Plates of blocker (12) are made with the possibility of bending, when passing locking ribs of cover (10), without damage, ensuring free tightening of bolt (13) into the body of case (1) of CLSD, with the possibility of stopping in ribs of cover (10), when trying to unscrew cover (10) with bolt (13) from case (1) of CLSD. An external indicator of complete tightening of cover (10) is its docking without a gap with outer metal ring (7) of the case of CLSD, mounted on the pipe of case (1). An outer diameter of ring (7) is selected in such a way that to exclude access to plates of blocker (12), which is in the closed state. CLSD with a radio frequency identification tag integrated into the piece of the rope as the central core of end-glow fiber in a protective polymer shell and CLSD are also proposed.

EFFECT: fixation of a rope without the possibility of its removal without causing visible damage, acceleration of the process of checking the integrity of the steel rope of LSD, remote automatic reading of data from LSD tag.
