JOINTING UNIT Russian patent published in 2013 - IPC F16B1/00 

FIELD: machine building.

SUBSTANCE: jointing unit comprises two sections made as capable of interaction with a support end element protruding beyond the edge of one of sections and fixators arranged evenly along the perimetre of the first section. Each fixator is made in the form of a sleeve fixed on the side surface of the first section with an axis parallel to its axis, aligned by the end to the edge of the section and equipped with an insert installed as capable of axial displacement inside the sleeve, in the side surface of which there is a round hole and a slot arranged one after the other from its end. The longitudinal axis of the slot is parallel to the axis of the sleeve and is arranged in the plane stretching via the axis of the sleeve and the axis of the section. The insert is equipped with a pin, installed in its first pin and stretching via the bottom of the sleeve asymmetrically to its axis, is arranged as capable of interaction with the first end to the bottom of the sleeve, contacts by the second end with the compression spring installed in the sleeve at the side of its end. It is made with two non-through holes perpendicular to its axis and equipped with compression spring, a sphere and a plunger for interaction with the round hole and the slot of the sleeve. It is made with a bore forming with its hole, equipped with a sphere, an edge for interaction at the side of the hole with the sphere in the point arranged at circumference with diameter less than the diameter of the sphere made with the diameter that is more than the width of the slot and the diameter of the round hole of the sleeve. The plunger is made stepped, besides, the diameter of the larger step is equal to the diameter of the insert hole, and the smaller one - to the width of the sleeve slot. The second section is equipped with longitudinal planks, every of which is equipped with a collar protruding beyond the end ledge, which has a hole for interaction with the step of the plunger of the smaller diameter after interaction with one of the sections with the support end element of the other one.

EFFECT: enhanced reliability and operational capabilities.
