A rotating shaft of the armature is connected by an armature support and is an adjusting nail, the adjusting nail penetrates through the armature support and an axle hole on one side of the armature sequentially and then penetrates out of the armature and the other side of the armature support after being sleeved with an adjusting spring, and a locking spring preventing the adjusting nail slip off radially is sleeved at the tail end of the adjusting nail. The hydraulic electromagnetic circuit breaker is reasonable in structure, convenient in adjustment and capable of increasing overload protection reliability and precision greatly.
Description
[technical field]
The utility model relates to a kind of hydraulic electromagnetic breaker.
[background technology]
We know, circuit breaker has been widely used in the circuit control structure, and circuit breaker mainly contains two kinds of Thermomagnetic type and hydraulic-electromagnetics, and wherein hydraulic electromagnetic breaker can not be subjected to the variation of ambient temperature influence, advantage with reliability height and working stability is so its application is more and more popularized.The operation principle of hydraulic electromagnetic breaker is such: when overcurrent; electromagnetic coil assembly produces enough big magnetic force armature is inhaled in the past; armature swing back drives moving contact by leverage and leaves fixed contact; spring force and electromagnetic coil assembly that control armature rotates are extremely important to armature magnetic equilibrium of forces, are related to the sensitivity and the accuracy of circuit breaker overload protection.But; present stage; these sensitivity and accuracy are by the machining accuracy of parts such as armature and install and realize; this is not only very high to the requirement of processing and installation; improved production cost greatly, and the time all there is certain error in a plurality of part in assembling, this can reduce accuracy greatly; just be difficult to free adjustment in case install, so the reliability of the overload protection of current hydraulic electromagnetic breaker and accuracy are lower.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and the hydraulic electromagnetic breaker that a kind of rational in infrastructure, adjustment is convenient, can improve the accurate adjusting function of tool of overload protection reliability and accuracy is provided.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
The hydraulic electromagnetic breaker of the accurate adjusting function of a kind of tool, include pedestal and the executor, armature, moving contact, fixed contact, electromagnetic coil assembly, leverage, face terminals and the binding post that are arranged in the pedestal, the rotating shaft of described armature is connected by armature bracket, the rotating shaft of described armature is for regulating nail, this adjusting nail pass successively armature bracket and armature one side axis hole, put that the axis hole from armature and armature bracket opposite side passes behind the regulating spring, follow closely tail end in this adjustings and be with and prevent to regulate the locking spring that nail radially skids.
In the improvement project to the hydraulic electromagnetic breaker of the accurate adjusting function of above-mentioned tool, the two ends of described regulating spring act on respectively to be regulated on nail and the armature, and described locking spring is a torsion spring, and its two ends are inserted in the location hole of this armature bracket.
In improvement project to the hydraulic electromagnetic breaker of the accurate adjusting function of above-mentioned tool, have an elongated slot in the adjustable side of described adjusting nail, an end of described regulating spring slides in this elongated slot.
Compared with prior art; the beneficial effects of the utility model are: because the rotating shaft of armature is for regulating nail; this adjusting nail passes the axis hole of armature bracket and armature one side successively; put that the axis hole from armature and armature bracket opposite side passes behind the regulating spring; be with at this adjusting nail tail end and prevent to regulate the locking spring that nail radially skids; when normal operating conditions; be in reset mode at regulating spring effect lower armature; when overload; electromagnetic coil assembly overcomes behind the active force of regulating spring armature inhaled to be made it to rotate and reach moving around regulating nail in the past; fixed contact separates and cuts off the power supply; reach the purpose of overload protection; so just can regulate the torsion that nail comes adjustment armature to rotate around the axis by turning; thereby when assembling or safeguarding the accuracy of armature take-off; can turn at any time to regulate to follow closely and realize; need not to resemble present stage by the machining accuracy of part and as far as possible accurately installation realize; so it is of the present utility model rational in infrastructure; adjustment is convenient, can improve overload protection reliability and accuracy greatly.
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

Fig. 2 is the stereogram (back apparent direction) of the utility model embodiment;
Fig. 3 is the stereogram of the adjustment structure of the utility model embodiment;
Fig. 4 is the assembling schematic diagram of Fig. 3.
[embodiment]
The utility model is the hydraulic electromagnetic breaker of the accurate adjusting function of a kind of tool, as shown in Figure 1, 2, include pedestal 1 and the executor 2, armature 3, moving contact 4, fixed contact 5, electromagnetic coil assembly 6, leverage 7, face terminals 8 and the binding post 9 that are arranged in the pedestal 1, the rotating shaft 10 of described armature 3 is connected by armature bracket 11.At this; as shown in Figure 3-4; the rotating shaft 10 of described armature 3 is for regulating nail; this adjusting nail passes the axis hole of armature bracket 11 and armature 3 one sides successively; putting regulating spring 12 back axis holes from armature 3 and armature bracket 11 opposite sides passes; be with at this adjusting nail tail end and prevent to regulate the locking spring 13 that nail radially skids; when normal operating conditions; be in reset mode at regulating spring 12 effect lower armatures; when overload; electromagnetic coil assembly overcomes behind the active force of regulating spring armature inhaled to be made it to rotate and reach moving around regulating nail in the past; fixed contact separates and cuts off the power supply, and reaches the purpose of overload protection.So just can follow closely adjustment armature 10 torsion that rotate around the shaft by turning to regulate; thereby when assembling or safeguarding the accuracy of armature take-off; can turn at any time to regulate to follow closely and realize; need not to resemble present stage by the machining accuracy of part and as far as possible accurately installation realize; so rational in infrastructure, adjustment convenience of the present utility model can improve overload protection reliability and accuracy greatly.
In the present embodiment, as shown in Figure 3-4, the two ends of described regulating spring 12 act on respectively to be regulated on nail 10 and the armature 3, and described locking spring 13 is a torsion spring, and its two ends are inserted in the location hole 111 of this armature bracket 11.
As shown in Figure 4, have an elongated slot 101 in the adjustable side of described adjusting nail, an end 121 of described regulating spring 12 slides in this elongated slot 101, and screwdriver can be inserted in the elongated slot and regulates when adjustment like this.
