RAPID-ACTION COUPLING Russian patent published in 2009 - IPC F16B21/02 F16B21/06 

FIELD: machine building.

SUBSTANCE: invention refers to machine building and can be implemented in structures requiring frequent and quick disconnection. Rapid-action coupling consists of a cylinder rod inserted in holes of coupled parts and a fixing spring; also the cylinder rod has an end with a head and a free end. The fixing spring is equipped with clamps and is made with two parallel branches having ends secured on a coupled part with clamps on opposite relative to the head of the rod side. The free end of the rod is made with two parallel relative to each other flats and correspondingly with two grooves. Flats and grooves are arranged mutually perpendicular relative to each other. Dimension of flats facilitates free travel of the free end of the rod between the branches of the fixing spring. Dimension of grooves ensures total embedding of branches of the fixing spring in them at the moment of completion of coupling parts and during operation.

EFFECT: increased efficiency of device operation due to simplicity and reliability of design; possibility to assemble and disassemble coupling with one hand; also possibility to assemble and disassemble coupling not accessing rod from side of fixing spring.
