It crosses pivot pin two to be articulated in fixed plate, the other end opens up strip-shaped hole two, and the pivot pin one is located in strip-shaped hole two；The junction panel
Middle part be fixed with tension spring, the other end of the tension spring passes through connecting lever linkage counter.
In above scheme, duct is opened up in the fixed plate between division indicator and counter, the connecting lever is worn
Cross the duct.
In above scheme, the counter is mechanical not reset count device, the connecting lever and the mechanical not reset count
Gear connection inside device.
Through the above technical solutions, ISM breaker division instruction provided by the utility model and counting device are using chain
Plate, tension spring, connecting lever frame mode, drive brake cable to realize separating brake and closing operation by breaker body, while pivot pin one drives
Junction panel and return spring movement, division indicator board show separating brake or combined floodgate, will drive connecting lever fortune by the tension spring on junction panel
It is dynamic, and then counter is driven to count, present apparatus division instruction is reliable, and breaker actuation counts accurate.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe.
The utility model provides a kind of ISM breaker division instruction and counting device, as shown in Figure 1, the apparatus structure
Simply, sensitive, division instruction is reliable, and it is accurate to count.
ISM breaker division instruction as shown in Figures 2 and 3 and counting device, including being fixed in circuit breaker frame
Fixed plate 1,1 front of fixed plate are equipped with division indicator 2 and counter 3, and strip-shaped hole 1, division instruction are opened up in fixed plate 1
The return spring 6 connecting with division indicator board 5, the connection of 6 other end of return spring are provided in device 2 at the position of strip-shaped hole 1
Brake cable 7 and pivot pin 1, pivot pin 1 can slide in strip-shaped hole 1.
1 back side of fixed plate is equipped with junction panel 9, and 9 one end of junction panel is articulated in fixed plate 1 by pivot pin 2 10, another
End opens up strip-shaped hole 2 11, and pivot pin 1 is located in strip-shaped hole 2 11；The middle part of junction panel 9 is fixed with tension spring 12, tension spring 12 it is another
One end passes through 13 linkage counter 3 of connecting lever.Duct 14 is opened up in fixed plate 1 between division indicator 2 and counter 3, is turned
Arm 13 passes through duct 14.
In the present embodiment, counter 3 is mechanical not reset count device, the tooth inside connecting lever 13 and mechanical not reset count device
