PNEUMATIC OR HYDRAULIC DRIVE MECHANICAL STANDBY Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: spindle is mounted in the axial threaded hole of a body. A tightening cap with inner thread is mounted on the outer thread of the body. A rod is rigidly connected to the cap and two pins with spherical surfaces on the ends. A bore with a conical end surface is made in the body coaxially to the hole, a blind axial hole and two through radial holes intersecting it are made in the spindle. The rod is positioned in the axial hole, the pins - one at a time in radial holes for engagement by one end with the conical surface of the bore and by the other one - with the rod. EFFECT: improved structure. 2 dwg
