LOCKING AND SEALING DEVICE Russian patent published in 2021 - IPC E05B39/02 

FIELD: objects sealing.

SUBSTANCE: invention is intended for locking and sealing objects where it is advisable to use a flexible connection in the form of a piece of cable, for example, such as wagons and containers of railway transport, warehouses, warehouses, shops, stalls, hatches and cars, as well as transported goods in all types of transport. The locking and sealing device contains an inlet plug (11) fixed in the body by pressing, made in the form of a glass with a smooth outer cylindrical surface. A through hole is made in the bottom of the glass, the diameter of which corresponds to the diameter of the cable segment. The place in the body (2) for placing the inlet plug (11) is made in the form of an end groove with a smooth lateral cylindrical surface, the diameter of which is less than the diameter of the plug (11) and corresponds to the diameter of the lateral cylindrical surface of the body, and the depth is greater than the height of the plug (11). A cap (16) with a washer (15) made of a metal material and a gasket (17) made of rubber are placed inside the inlet plug (11). The height of the cap (14) and the thickness of the gasket (15) correspond to the depth of the inlet plug (11). Between the groove for the inlet plug (11) and the body cavity (2), designed to accommodate the spring-loaded detachable elements (5) and the frame (10), a through hole is made, the diameter of which corresponds to the diameter of the cable segment. The device is equipped with an additional washer (29) made of metal material, the diameter of which corresponds to the diameter of the outer cylindrical surface of the inlet plug (11). An additional washer (29) is placed in the cavity of the body (2) between the inlet plug (11) and the end surface of the frame (10) with split elements (5) and is made with a central hole, the diameter of which corresponds to the diameter of the cable segment. The end surface of the body (2) from the side of the inlet is made with an annular step to ensure, when pressing in the inlet plug (11), the rolling of its edges with the placement of the end surfaces of the body (2) and the inlet plug (11) flush, each of the protrusions of the split elements (5) made in the form of a geometric body, the lateral surface of which is formed by a part of the conical lateral surface of a straight circular cone, the top and central axis of which are located on the axis, passing along the bottom of the longitudinal semi-cylindrical recess parallel to its central axis, while the top is directed towards the inlet plug (11) when placing the split elements (5) in the body (2), and the base is made convex as a part of a spherical surface that smoothly mates with a conical side surface and a cylindrical side surface of a longitudinal recess, while on a part of the conical side surface of each protrusion, two open grooves with inclined flat surfaces are made opposite each other, each of which on one side mates with the spherical surface of the apex, and on the other side with a conical side surface, moreover, the inclined flat surfaces of the open grooves are located at an angle of 35-39 ° to each other symmetrically relative to the Y-Y plane passing through the central axis of the longitudinal recess and perpendicular to the outer inclined surfaces of the split elements.

EFFECT: increased reliability of the locking and sealing device by ensuring reliable force adhesion of the elements fixing the cable segment with the lateral surface of the cable segment, as well as increasing the convenience and simplification of the locking and sealing device manufacturing process.
