Set it is generally existing structure is complicated, the problem of installation and debugging inconvenience.
Existing Universal circuit breaker operating mechanism is all mounted between two blocks of side plates and is equipped with shuttle-type instruction point
Combined floodgate indicator, indicator are located at outside the front of operating mechanism to express other people.
Utility model content
Technical problem to be solved in the utility model, is just to provide that a kind of structure is simple, installation and debugging are convenient, Er Qiexing
The mechanical counting device of Universal circuit breaker operating mechanism can be reliably used for.
Above-mentioned technical problem is solved, the utility model adopts the technical scheme that
A kind of mechanical counting device for Universal circuit breaker operating mechanism, the circuit breaker operation mechanism installation
Between both side plate 7 and it is equipped with shuttle-type instruction divide-shut brake indicator 6, indicator 6 is located at outside the front of operating mechanism,
Be characterized in include:
One fixed plate 2 is fixed on the outside of one of described both side plate 7；
One rotary type mechanical counter 1 is fixed in the fixed plate 2；
One Rocker arm 4, one end is secured transversely in the shaft of rotary type mechanical counter 1, the other end connects a spring 3
One end；
One drive rod 5, one end are fixed on instruction divide-shut brake indicator 6, and the other end is then connected to the other end of spring 3；
The design and installation of above-mentioned each component, should make circuit breaker operation mechanism in "on" position, and Rocker arm 4 is in nature
Home position；When operating mechanism carries out a sub-switching operation, indicator comparative counting device 1 is moved downward, to stretch connection
Spring 3 above it counts rotary type mechanical counter 1 once；When operating mechanism carries out a closing operation, open circuit
Device is restored to "on" position.
Preferably, the fixed plate 2 bending plate as made of sheet metal punching bending, including orthogonal stationary plane
With 1 mounting surface of counter, stationary plane is fixed on the left side side plate of the operating mechanism by the fixed plate by fixing screws,
The counter is fixed on the counter mounting surface by screw.
The Rocker arm 4 be it is rod-shaped, one end is provided with transverse holes connecting spring, the other end and is milled with axial pass through inward from end
Logical groove penetrates through inside groove and is provided with lateral semicircle groove to clamp counter spindle nose, penetrates through the two halves outside groove
Part has clamping threaded hole and circular hole, is screwed with fishbolt.
The utility model has the advantages that the utility model structure is very simple, dexterously installs additional and drive on the indicator of operating mechanism itself
Lever limits fixed Board position as driving point, and using boss of the operating mechanism inner shaft on side plate, only with a screw
Fixed fixed plate, to facilitate installation and debugging.So that present apparatus structure is very simple, reliable performance is solved for the above design
Structure is complicated for similar counting device, the problem of installation and debugging inconvenience.
