In addition, at least one recess is made in the housing to accommodate the sealing plug, the shape and dimensions of which correspond to the shape and dimensions of the sealing plug.

Closest to the proposed is the device described in patent RU No. 2104910 (class B65D 55/06).

The device comprises a cable segment and its fixing elements located in the housing, made with the possibility of hard circuit with its lateral surface of one or two ends of the cable segment. The other end can be rigidly connected to the tip made with a through hole with the possibility of passing through it the free end of the cable segment to form a loop of the required size, or the other end of the cable can be rigidly connected to the sealing element. The locking elements are made in the form of two separate elements with an internal gear surface corresponding to the internal surface of the housing, which can be either conical or flat inclined.

The serrated surface can be made in the form of a screw thread, the angle of inclination of which corresponds to the angle of inclination of the cable strands. The teeth of the gear surface can be made one-sided and two-sided beveled.

Known devices provide reliable fixation of a flexible element with a simple technology for their manufacture.

The technical result of the invention is the expansion of the arsenal of means for fixing a segment of a rope using segmented cams with a passage channel having notches or screw threads.

SUMMARY OF THE INVENTION

The specified technical result is achieved in that in a flexible locking and sealing device containing a piece of rope having free and passive ends, and a housing with inlet and outlet openings and with an internal conical surface interacting with the corresponding external surface of two spring-loaded conical segmented cams with a passage channel , the inner surface of which includes a screw thread, while the outlet is made in the lid covering the cavity, according to the invention, cams with one the inlets of the inlet are provided with a cylindrical inlet, the diameter of which is equal to at least the diameter of the segment of the rope, and screw cutting on each cam is made on an arc of a segment whose radius exceeds the radius of the inlet, and its center is located on an axis in a plane perpendicular to the plane of the cams offset relative to it, and the offset radius is chosen such that in the position of the device prepared for locking, the distance between the vertices of the ribs of the screw thread is less than half the diameter of the segment of the channel ta.

As well as the fact that there is a place on the case for the application of a control identification marking.

Below the invention is illustrated by way of example with the accompanying drawings.

Preferred Embodiment

A flexible locking and sealing device contains a segment of a rope 1 having free 2 and passive 3 ends, and a housing 4 with an inlet 5 and an outlet 6 holes and with an inner conical surface 7 interacting with the corresponding outer surface 8 of two spring-loaded conical segmented cams 9 with a passage channel 10, the inner surface of which includes a screw thread 11.

When this outlet 6 is made in the cover 12, covering the cavity of the housing 4.

According to the invention, the cams 9 on the inlet side 5 are provided with a cylindrical inlet part 13, the diameter of which is equal to at least the diameter of the rope segment 1, and the screw thread 11 on each cam 9 is made on the arc of the segment 14, whose radius “R” exceeds the radius “r” the input part, and its center “O ₁ ” is located on an axis in a plane perpendicular to the plane of the connector 15 of the cams 9 with an offset “E” relative to it.

Moreover, the size of the offset "E" is chosen so that in the position of the device prepared for locking, the distance "L" between the vertices of the 16 edges of the screw thread is less than half the diameter "d" of the rope segment.

On the housing 4 there is a place for applying a control identification marking.

Locking objects when using a locking and sealing device is performed manually as follows.

The free end 2 of the flexible element - the segment of the rope 1 - is sequentially passed through the combined holes of the locking nodes of the sealed objects, after which it is introduced into the inlet 5 of the housing 4.

Then the free end of the rope, abutting against the end of the inlet 13, simultaneously moves both cams 9 along the axis of the casing and spreads them along the inner conical surface 7. The movement of the cams ends when the distance between the vertices of the screw cutting ribs in the cams reaches the diameter of the rope segment 1.

After the formation of a loop of the minimum size, the spring 17 moves the cams 9 upwards, due to which the vertices of the screw cutting ribs in the cams, interacting with the lateral surface of the rope segment 1, are partially pressed into it, ensuring reliable adhesion to its surface.

Moreover, the indentation into the lateral surface of the rope segment first occurs on the sides of the arc of segment 14, on which each cam is screwed, and the resulting swelling on the rope segment 1 fills the entire passage channel 11, ensuring its reliable fixation.

Thus, the proposed design, in which the screw cutting is performed on an arc of a segment, the radius of which exceeds the radius of the input part, and the center is located on an axis in a plane perpendicular to the plane of the cam connector with an offset relative to it, and the offset size is selected such that in the position of the device, prepared for locking, the distance between the vertices of the screw cutting ribs is less than half the diameter of the rope segment, provides a more reliable fixation of the rope segment than the known structures, in which hydrochloric channel is coaxial with the cylindrical screw thread.
