In the prior art, normally used all is large-scale breaker of plastic casing, snap close hook in its lock for circuit breaker buckle device is consistent with the direction of distribution box handle rotation, in use, transfers disconnection and the closure function that drives snap close hook realization circuit breaker by the dextrorotation of distribution box handle.Yet when the distribution box circuit breaker dwindled, because the distribution box handle dwindles, after auxiliary contact were installed, the clockwise direction of distribution box handle will be stopped by auxiliary contact, makes the distribution box handle to turn clockwise, and is difficult to realize the snap close function.
And existing distribution box circuit breaker is when being in closure state, and distribution box still allows to lock, and when deenergization rapidly takes place accident, has stayed potential safety hazard.
Therefore, need a kind of machine room distribution box miniature circuit breaker locker especially, to address the above problem.
The utility model content
The utility model purpose is to provide a kind of machine room distribution box miniature circuit breaker locker, after distribution box lock for circuit breaker buckle device dwindles in the solution prior art, the distribution box handle can't turn clockwise and realize the snap close function, and the distribution box circuit breaker is when being in closure state, distribution box still allows to lock, and is difficult to the problem of rapid deenergization in accident.
To achieve these goals, the technical solution of the utility model:
A kind of machine room distribution box miniature circuit breaker locker, it is characterized in that, it comprise a distribution box handle, that is rotated counterclockwise follow distribution box latch hook, that the distribution box handle rotates be arranged on the circuit breaker handle and of distribution box latch hook below can be along with the movable jam plate of distribution box latch hook move left and right, described distribution box latch hook is fixedly installed on distribution box handle rear, and distribution box latch hook and movable jam plate are rotatedly connected.
In an embodiment of the present utility model, described distribution box latch hook when distribution box handle and horizontal level are 0 ° and circuit breaker handle offset.
In an embodiment of the present utility model, described distribution box latch hook when the distribution box handle is rotated counterclockwise 45 ° and circuit breaker handle be complementary.
In an embodiment of the present utility model, described distribution box latch hook when the distribution box handle is rotated counterclockwise 90 ° with circuit breaker handle from.
In an embodiment of the present utility model, the below of described distribution box handle also is provided with an arc direction board that is complementary with the distribution box handle.
Machine room distribution box miniature circuit breaker locker of the present utility model, after distribution box lock for circuit breaker buckle device dwindles in the solution prior art, the distribution box handle can't turn clockwise and realize the snap close function, and the distribution box circuit breaker is when being in closure state, distribution box still allows to lock, accident is difficult to the problem of rapid deenergization when taking place, change to by the direction of rotation with the distribution box handle and to be rotated counterclockwise, realized the switching function of miniature circuit breaker locker effectively, and by movable jam plate is set, make circuit breaker when being in closure state, can't lock, deenergization rapidly when avoiding accident to take place has solved potential safety hazard, has improved fail safe and the practicality of miniature circuit breaker locker widely.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
