FIELD: electromechanical control devices, particularly to control rotary member (rotor) of the turnstile. ^ SUBSTANCE: rotor control mechanism has base with side wall, driving disc with rollers, pusher with pressing plate and spring, two electromagnets and two arresting toggles. Pusher has roller arranged on pressing plate. Roller pin is displaced relative disc pin to form lever, which provides moment of force enough to prevent disc stop in point of driving disc movement from one fixed position to another one. Working surface of pressing plate has inclinations to reduce swing speed of drive disc during movement thereof into fixed position. ^ EFFECT: elimination of driving disc stop (deadlock) in point of driving disc movement from one fixed position to another one, reduced swing speed during disc displacement into fixed position. ^ 4 dwg |
