EASILY DETACHABLE CONNECTION PIN Russian patent published in 2001 - IPC

FIELD: machine engineering, possibly apparatuses for fixing weights needing easy and repetitive connection-disconnection of parts. SUBSTANCE: easily detachable connection pin includes rod with handle in one end and fixing elastic unit in other inlet end. Fixing elastic unit is in the form of fixing bending spring mounted in slit passing along rod axis. Inlet ends of fixing bending spring protruding from slit are directed towards handle and they have two portions inclined one relative to another by 90 degrees and engaging respectively with body of one of joined parts and with supporting ring rigidly secured to inlet end of rod by means of dowel. The last is joined with curvilinear portion of fixing spring and it is arranged near end surface of inlet end of rod normally relative to its axis and relative to planes of axial slit in through opening passing through inlet end of rod and supporting ring. It provides improved carrying capability of connection pin. EFFECT: simplified technique for making and assembling easily detachable connection pin. 2 dwg
