Abstract
Disclosed in the utility model is an operating device of opening and closing of a circuit breaker. The operating device comprises a manual operating mechanism, an electric operating mechanism and a manual/electric switching mechanism. The manual operating mechanism a gear rack, a connecting support arranged on the gear rack and an operating handle; on end of the gear rack is connected with a connecting rod extended out of a middle cover of the circuit breaker; the connecting support is arranged at one end, approaching the operating rod, of the gear rack and is plugged with an insertion slot arranged at the bottom end of the operating handle to enable the operating handle and the gear rack to be connected; and the gear rack and the connecting support are integrated into one. According to the utility model, the operating device has a reasonable structure; and the connecting support is firm, wherein the function of the connecting support is equal to that of a connector mentioned in the patent documentation CN201332078Y.
Description
Technical field
The utility model belongs to the breaker structure design field, is specifically related to a kind of circuit-breaker switching on-off operating means.
Background technology
Patent documentation CN201332078Y discloses a kind of residual current circuit breaker engage a gear formula breaking-closing operating device, partly record " the circuit breaker handle cover has metallic sheath and is connected with connector with handle pin; have elongated slot on end in the connector middle part; handle pin can only be done horizontal movement in elongated slot, the connector bottom is separately fixed at the slot two ends of slip tooth plate upper middle position with four screws " in its specification embodiment.Wherein, connector is to be fixedly connected with the slip tooth plate by screw, thereby uses through long-term frequent, and it is loosening even come off and then make circuit breaker lose the ability of manual breaking-closing operating that the loosening connector that causes can occur screw.
The utility model content
For above shortcomings among the patent documentation CN201332078Y, the purpose of this utility model provides that a kind of structure is comparatively simplified, the firm circuit-breaker switching on-off operating means of connection bracket (being equivalent to the connector among the patent documentation CN201332078Y).
The technical scheme that realizes the utility model purpose is:
A kind of circuit-breaker switching on-off operating means comprises manual-operating mechanism, motor-operating mechanism and manual/electric switching mechanism;
Described manual-operating mechanism comprises tooth bar, is arranged on connection bracket and operating grip on the tooth bar; One end of described tooth bar links to each other with the action bars that stretches out the circuit breaker middle cover, and described connection bracket is located at described tooth bar makes operating grip be connected with tooth bar near an end of action bars and by pegging graft with the slot of being located at described operating grip bottom;
Described tooth bar and described connection bracket are integrated part (integral piece, relative with the split part, the split part need to connect by securing member, integral piece is then opposite, need not securing member) when connecting.
In the above-mentioned circuit-breaker switching on-off operating means, described connection bracket is by tooth bar one or both sides plate body upwards is bent to form.
In the above-mentioned circuit-breaker switching on-off operating means, described connection bracket is welded on the described tooth bar.
In the above-mentioned circuit-breaker switching on-off operating means, be connected thereby described action bars places the through hole that is located on the described tooth bar to form with described tooth bar, be provided with stiffener in the periphery of described through hole.
The utlity model has positive effect:
(1) in the utility model by tooth bar and connection bracket are made as integral piece, rather than by screw or other securing members the two is fixedly connected with, not only simplify its structure, can effectively avoid connection bracket that phenomenon loosening even that come off occurs in long-term the use simultaneously.
(2) thus be connected by action bars being placed the through hole that is located on the described tooth bar form with described tooth bar in the utility model; and be provided with stiffener in the periphery of described through hole; adopt this structure namely to increase the contact area of tooth bar and action bars; so that action bars is difficult for because of stressed excessive the fracture, play the effect of protection action bars.

Embodiment
Below in conjunction with Figure of description the circuit-breaker switching on-off operating means in the utility model is elaborated:
A kind of circuit-breaker switching on-off operating means, as depicted in figs. 1 and 2, it comprises manual-operating mechanism, motor-operating mechanism and manual/electric switching mechanism; Described manual-operating mechanism comprises tooth bar 1, is arranged on connection bracket 2 and operating grip 3 on the tooth bar 1; One end of described tooth bar 1 links to each other with the action bars 4 that stretches out circuit breaker middle cover 5, and described connection bracket 2 is located at described tooth bar 1 makes operating grip 3 be connected with tooth bar 1 near an end of action bars 4 and by pegging graft with the slot 31 of being located at described operating grip 3 bottoms; Described tooth bar 1 is integrated part with described connection bracket 2, and is concrete, and the connection bracket 2 in the present embodiment is the bending and moldings that make progress of the plate body with tooth bar 1 both sides, also the side plate body of tooth bar 1 can be made progress bending as connection bracket 2 in practical operation.
Further distortion as said structure: can adopt and connection bracket 2 is welded on the tooth bar 1 part so that connection bracket 2 and tooth bar 1 are combined as a whole.
Three kinds of modes of operation of tooth bar 1 and connection bracket 2 being made integral piece in such scheme, have been provided, can save and adopt screw or other securing members with the two assembly process that is fixedly connected with by tooth bar 1 and connection bracket 2 being made integral piece, simplify its structure, effectively avoided connection bracket 2 that phenomenon loosening even that come off occurs in long-term the use simultaneously.
As shown in Figure 3, be connected thereby described action bars 4 places the through hole 11 that is located on the described tooth bar 1 to form with described tooth bar 1, be provided with stiffener 12 in the periphery of described through hole 11.Adopt this structure namely to increase the contact area of tooth bar 1 with action bars 4, so that action bars 4 is difficult for because of stressed excessive the fracture, play the effect of protection action bars 4.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And these belong to apparent variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.
