The invention relates to mechanical engineering, in particular to devices for holding ropes, namely, to stoppers for clamping mooring lines.

The purpose of the invention is to improve the operating conditions by increasing the level of safety and increasing speed.

FIG. 1 shows the stopper, general view; in fig. 2 shows a section A-A in FIG. 1 (the clamping element is rotated); in fig. 3 - hook, general view; in fig. 4 - clamping element; in fig. 5 - insert, general view; in fig. 6 - the same, side view.

The portable stopper contains two parallel cheeks 1 and 2 connected by screws 3, on one of which there is a bracket 4 for fastening a chain or a rope holding the stopper. On the ends of the 5 cheeks parallel to their longitudinal axis, there are guides 6 in which and rotation is installed the washer 7 of the support element 8, protruding above the ends 5.

The inclined ends of the 9 cheeks are in contact with the washer of the joint 10 of the ball 11. The latter is further mounted on the supporting rod 12 of the hook 13, which by the supporting rod 12 is placed in the axial hole 14 of the supporting element 8 having a recess 15 on the working surface 15 for the cable 16. The hook rotates around its axis. At the end of the support rod set the handle 17-control. Attachments 18 for ropes of reduced diameters are attached to the hook.

The stopper works under conditions of high loads that cannot be

held by hand.

The cable 16 is fastened to the bracket 4, and on it the stopper is lowered over the extended end of the cheeks 1 and 2 down. Chelo

The eyelid in the boat catches the stopper by the handle 17, which can rotate with the hook 13 and the supporting element 8 to any convenient position, and moves the hook 13 towards the narrowing of the wedge guide cheeks 1 and 2, expanding the entrance above the supporting element 8. Holding The cable is inserted into the shed of the hook 13 and the handle 17 is released. Under the weight of the cable, the hook itself and other elements or from the force on the cable, the hook 13 moves along the cheeks to the place of their expansion and tightens the cable held between the insert 18 (or the hook shed) and supporting element 8.

The position of the handle and the hook is indifferent.

The stopper with the cable 16 clamped in the hook 16 is hanging, held by the bracket 4.

If the cable needs to be released, the hook is knocked out of the hook in the direction of narrowing of the cheeks 1 and 2 and the cable is withdrawn from the throat.
