Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, can be easier to make advantage of the present utility model and feature be understood by those skilled in the art.
fig. 1 is to Figure 4 shows that a kind of circuit breaker of the present utility model.Shown in composition graphs 1 to Fig. 4, this circuit breaker comprises casing 1, motor 2, gear drive 3, clutch discs 4, unilateral bearing 5, driving shaft 6, sensitive switch 7, rotating part 8 and indicating dial 8.
motor 2, is arranged on below casing 1, for the actuating force providing clutch discs 4 to rotate.Also motor 2 can be replaced to provide actuating force for clutch discs 4 by manpower.Therefore, circuit breaker has manual operation and electric operating two kinds of modes of operation.
gear drive 3, is connected between motor 2 and clutch discs 4, for the actuating force of motor 2 is passed to clutch discs 4.
clutch discs 4, rotates for driving driving shaft 6.The edge of clutch discs 4 is formed with a circle tooth bar, one of them gear in rack and pinion transmission mechanism 3 is meshed.
unilateral bearing 5, for being delivered to driving shaft 6 by actuating force.One-way shaft has the inner ring 52 be fixedly connected with driving shaft 6, the outer ring 51 be fixedly connected with clutch discs 4, and inner ring 52 can outer ring 51 one-directional rotation relatively.Inner ring 52 is sheathed on described driving shaft 6, and outer ring 51 to be sheathed on inner ring 52 and to coordinate rotationally in inner ring 52, and the middle part of clutch discs 4 offers installing hole, and outer ring 51 is plugged in described installing hole.When clutch discs 4 is rotated in a first direction, driving shaft 6 is driven by clutch discs 4 and is rotated in a first direction; When clutch discs 4 is rotated along the second direction contrary with first direction, driving shaft 6 is static.In manual operation, when operating personnel's misoperation, namely, when clutch discs 4 is rotated in a second direction, by operating personnel, or in electric operating, when the faults such as motor 2, transmission mechanism 3 make clutch discs 4 be rotated in a second direction, skid between the outer ring 51 of unilateral bearing 5 and inner ring 52, driving shaft 6 is static, can not rotate, and effectively can avoid the parts damages caused because of driving shaft 6 backwards rotation.
driving shaft 6, for switching gate-dividing state and the "on" position of circuit breaker.Driving shaft 6 to be located in rotationally on casing 1 and to have and is positioned at top above casing 1, is positioned at bottom below casing 1.
switch, is fixedly installed on below casing 1.Sensitive switch 7 selected by switch in the present embodiment, and sensitive switch 7 has the contact be positioned on its shake-up spring.
rotating part 8, is set in driving shaft 6 lower end and drives rotation by driving shaft 6.Rotating part 8 to be positioned at below casing 1 and to maintain an equal level mutually with the contact of sensitive switch 7 and arranges.The edge of rotating part 8 forms the first induction part 81, second induction part 83, two transition parts 82, transition part 82 lays respectively between the first induction part 81 and the second induction part 83, and the first induction part 81, one of them transition part 82, second induction part 83, another transition part 82 first place connect successively, the first induction part 81, transition part 82, second induction part 83 all maintain an equal level mutually with contact.Wherein, the first induction part 81 any point is all greater than the distance of the second induction part 83 any point to driving shaft 6 axial line to the distance stating driving shaft 6 axial line.Particularly, the first induction part 81 and the second induction part 83 all curved, and the center of circle of two arcs is all on the axial line of driving shaft 6, and the radius of arc that the first induction part 81 is formed is greater than the radius of the arc that the second induction part 83 is formed.
in the process that rotating part 8 rotates with driving shaft 6, when the first induction part 81 turn to be positioned at the same side of driving shaft 6 with sensitive switch 7 time, the first induction part 81 pushes against with the shake-up spring of sensitive switch 7 and contacts, and contact is triggered, sensitive switch 7 is connected, and circuit breaker is in gate-dividing state; When the second induction part 83 turn to be positioned at the same side of driving shaft 6 with sensitive switch 7 time, the second induction part 83 cannot with the contact of sensitive switch 7, be namely separated, sensitive switch 7 disconnects, and circuit breaker is in "on" position; When arbitrary transition part 82 turn to be positioned at the same side of driving shaft 6 with sensitive switch 7 time, under-voltage release that sensitive switch 7 has controls sensitive switch 7 and is in trip status.
indicating dial 8, is set in driving shaft 6 upper end and drives rotation by driving shaft 6.Indicating dial 8 to be positioned at above casing 1 and with rotating part 8 synchronous axial system.Indicating dial 8 has the first indicating area 91 being used to indicate gate-dividing state, the 3rd indicating area 93 that 92, two, the second indicating area being used to indicate "on" position is used to indicate trip status.Wherein, the first indicating area 91 and the first induction part about 81 correspondence are arranged, and the second indicating area 92 and the second induction part about 83 correspondence are arranged, and two 93 respectively with two, the 3rd indicating area transition part about 82 correspondences are arranged.
breaker structure of the present utility model is simple, and parts are few, and it is clear and definite, clear to indicate, and cost is low, all can be able to indicate multiple operating states of circuit breaker.
above-described embodiment is only for illustrating technical conceive of the present utility model and feature; it is a kind of preferred embodiment; its object is to person skilled in the art can understand content of the present utility model and implement according to this, protection range of the present utility model can not be limited with this.All equivalent transformations of doing according to Spirit Essence of the present utility model or modification, all should be encompassed within protection range of the present utility model.
