Abstract
The utility model relates to a locking device of the circuit breaker shunt release, comprising a push rod, an indication button, an indication button spring and a plug, which is characterized in that: the shunt release is arranged on the cover of the circuit breaker; the push rod is sleeved on the shaft; the indication button is arranged in the indication button hole of the cover; one end of the indication button spring support the bottom of the indication button and the other end is connected with the plug; a limiting device is arranged at middle part of the indication button; a snap hook is arranged at the end of the limiting device; a guide groove is opened at the side edge of the indication button hole; the snap hook juts out of the guide groove of the cover; a bayonet, which is linked with the movable iron core of the shunt release, is arranged in the middle of the push rod; a locking foot, which is assembled to the snap hook of the indication button, is arranged at the end of the push rod. The locking device of the circuit breaker and shunt release has the advantages of simple structure, compact size and small volume.
Description
Technical field
The utility model belongs to the auxiliary equipment of circuit breaker, relates in particular to a kind of locking device of shunt release.
Background technology
Along with net capacity of China and improving constantly of automaticity, the user is more and more higher to the requirement of air circuit, especially shows small product size and combination property aspect.Present air circuit has had functions such as intelligence dropout, earth leakage protective, how to judge after the circuit breaker product trips it is because which kind of reason tripping operation becomes the principal element of circuit breaker combination property aspect.
Existing air circuit has all adopted the dropout instruction button on various dropout modular structures, and require to have locking device, can clearly determine is former thereby tripping operation because of which kind of, and is not in the lock state before fault is not got rid of, and can not carry out breaking-closing operating to circuit breaker.But will increase these functions in the circuit breaker inside of compact conformation the volume that reduces circuit breaker has been had new technological difficulties again, the shortcoming that existing dropout locking device exists: complex structure, volume be big, it is big to take up room.
Summary of the invention
For big, the big deficiency that takes up room of complex structure, volume that overcomes existing shunt release locking device, the utility model provide a kind of simple in structure, volume is little, the locking device that takes up room the circuit breaker shunt release little.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of locking device of circuit breaker shunt release, shunt release is installed on the lid of circuit breaker, described locking device comprises push rod, instruction button, instruction button spring and stopper, described pushing rod sleeve is contained on the axle, described instruction button is installed in the instruction button hole of described lid, the bottom that described instruction button spring one end withstands instruction button, the other end links to each other with stopper, the middle part of described instruction button is provided with stopping means, end at described stopping means is provided with grab, at the side openings gathering sill in described instruction button hole, described grab stretches out the gathering sill of described lid; The middle part of described push rod is provided with the bayonet socket with the moving iron core interlock of shunt release, and the end of described push rod is provided with the card base that cooperates with the grab of instruction button.
The beneficial effects of the utility model mainly show: 1, because parts are less, simple in structure, reduced the damage of parts, it is little to take up room; 2, performance is more stable.

Fig. 1 is the structure chart of the locking device of circuit breaker shunt release.
Fig. 2 is the generalized section of the locking device of circuit breaker shunt release.
Fig. 3 is the schematic diagram of push rod.
Fig. 4 is the schematic diagram of indication button.
Fig. 5 is the schematic diagram of indication button hole and gathering sill.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1-Fig. 5, a kind of locking device of circuit breaker shunt release, shunt release 5 is installed on the lid 7 of circuit breaker, described locking device comprises push rod 4, instruction button 1, instruction button spring 2 and stopper 3, described push rod 4 is sleeved on the axle 12, described instruction button 1 is installed in the instruction button hole 8 of described lid, the bottom that described instruction button spring 2 one ends withstand instruction button 1, the other end of described instruction button spring 2 links to each other with stopper 3, the middle part of described instruction button 1 is provided with stopping means 10, be provided with grab 11 in the end of described stopping means 10, side openings gathering sill 9 in described instruction button hole 8, described grab 11 stretch out guiding 9 grooves of described lid; The middle part of described push rod 4 is provided with the bayonet socket with the moving iron core interlock of shunt release, and the end of described push rod 4 is provided with the card base 14 that cooperates with the grab 11 of instruction button.
The course of work of present embodiment: structure as shown in Figure 1, when instruction button 1 was pressed, shunt release 5 relied on internal structure to automatically reset, and this moment, push rod 4 was pushed out, after unclamping instruction button 1, the grab 11 of instruction button 1 afterbody is just in time spacing the card base on the push rod 4 14.
When shunt release 5 hinders dropout for some reason, push rod 4 is driven by the moving iron core of shunt release, card base 14 on the push rod 4 separates because of stressed its grab 11 with instruction button 1 afterbody that forces, instruction button 1 is subjected to the effect of instruction button spring 2 power to make instruction button 1 be returned to original position, and is presented on 7 of the breaker covers; After moving iron core resetted, the card base on the push rod resetted, because the instruction button action, the stopping means 10 of instruction button has stopped card base 14, and card base 14 holds out against the side at stopping means 10; After fault is discharged, press instruction button downwards, then the grab 11 of instruction button afterbody and card base 14 clamping again on the push rod return to initial condition.
