Description
Technical field
The utility model relates to isolating switch field, particularly with the isolator operating mechanism of auxiliary locking device.
Background technology
The patent No. be 200820037237.7 utility model disclose a kind of operating mechanism of isolating switch, this operating mechanism is not arranged point, closing locking device, easily be subject to that exterior vibration or side knock make point, closing position changes, reliability and security performance lower.
Utility model content
The purpose of this utility model is to provide and a kind ofly operates isolator operating mechanism that is light, laborsaving, reliable operation, this operating mechanism energy Reliable guarantee isolating switch remains on point, closing position, and can not to occur point because being subject to exterior vibration or lateral impact forces, closing position changes.
The technical scheme realizing above-mentioned purpose is: with the isolator operating mechanism of auxiliary locking device, comprise isolating switch framework, isolating switch framework is provided with auxiliary locking device, described auxiliary locking device comprises operating mechanism fixed head, slide plate, connecting lever, connecting rod and operating axis, the both sides of described operating mechanism fixed head are respectively arranged with the slide bar be parallel to each other, sliding plate sleeve is contained on the slide bar of both sides, rod hinge connection is on slide plate, the slide plate of connecting rod side is provided with spacer pin, described operating axis is vertically fixed on one end of connecting lever, the other end of connecting lever and rod hinge connection, it is characterized in that: the isolating switch framework of connecting rod side is provided with steady pin, and steady pin and spacer pin are arranged on the homonymy of connecting rod, connecting rod and be connected with spring between the hinged one end of connecting lever and steady pin.
During work, operating mechanism fixed head is fixed on isolating switch framework, and operating axis can rotate around its axle center.
Turn clockwise operating axis under gate-dividing state, drive link forces slide plate to move downward along slide bar by the connecting lever be fixedly connected with operating axis, when connecting rod contacts with spacer pin, complete the closing operation of isolating switch, connecting rod remains on dead-centre position simultaneously under the effect of spring tension.
Counterclockwise rotary manipulation axle under "on" position, drive link forces slide plate upwards to do rectilinear motion along slide bar by the connecting lever be fixedly connected with operating axis, when connecting rod contacts with spacer pin, completes the sub-switching operation of isolating switch, equally, connecting rod remains on dead-centre position under the effect of spring tension.
The utility model makes this operating mechanism Reliable guarantee isolating switch remain on point by spring, closing position, ensure that the safety and reliability of isolating switch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model gate-dividing state.
Fig. 2 is the structural representation of the utility model "on" position.
