The advantageous effect of said structure is：There is the breaker of plastic casing simple in structure, stable and reliable for performance, divide-shut brake to indicate
The advantages of accurate, when breaker of plastic casing is in separating brake, moving contact acts upwards with contact rack, and contact rack promotes push rod, push rod pressure
Contracting spring and upwards action, the driving lever on push rod stir indicator swing, the red mark deviation indicator hole that closes a floodgate on indicator
One side, operating personnel can not see the red mark that closes a floodgate out of indicator hole, be indicated so as to fulfill the separating brake of the breaker；When disconnected
For road device when closing a floodgate, for moving contact with contact rack downward actuation, push rod loses the thrust of contact rack, push rod downward actuation, push rod band
Dynamic indicator is restored to original position, can see the red mark that closes a floodgate on arc indicating piece out of upper cover indicator hole so as to operating personnel
Will indicates so as to fulfill the combined floodgate of the breaker.
Particularly, an installing plate is respectively arranged on the both sides of the supporting rack, peace is both provided on each installing plate
Fill hole.Mounting hole is provided on supporting rack, entire switch-on/switch-off indicating mechanism can be one-time fixed by screw in middle cover
It is interior, convenient for the assembling of switch-on/switch-off indicating mechanism and middle cover, improve the efficiency of assembling of the breaker of plastic casing.
Particularly, the lower end of the push rod is extended in outside supporting rack, and pulley is movably set on the lower end of push rod,
The pulley is contradicted on the upper surface of contact rack.Pulley is provided on the lower end of push rod, pulley can ensure contact rack and push rod
Between transmission it is more reliable.
Description of the drawings
Fig. 1 is the utility model embodiment cut-away view.
Fig. 2 is the combined floodgate instruction state figure of the utility model embodiment switch-on/switch-off indicating mechanism.
Specific embodiment
As shown in Figure 1, 2, the utility model embodiment is a kind of breaker of plastic casing, including pedestal 10, middle cover 11, upper cover
