Abstract
The utility model discloses a driving device of a three-working-position load switch. The three-working-position load switch comprises an assembly plate and a connecting rod. One side of the assembly plate is provided with an input shaft A. One end of the input shaft A is assembled with an input crank arm A and a linkage crank arm A. The input crank arm A is connected with a spring guide rod A which is provided with a spring A. One end of the spring guide rod A is connected with a spring supporting rod A. Another side of the mounting plate is provided with an input shaft B. One end of the input shaft B is assembled with an input crank arm B and a linkage crank arm B. The input crank arm B is connected with a spring guide rod B. One end of the connecting rod is connected with the linkage crank arm A, and the other end of the connecting rod is connected with the linkage crank arm B. According to the driving device of the three-working-position load switch, compared with a driving device of an original three-working-position load switch, a mechanical fatigue problem caused by multiple operations of one spring is avoided.
Description
Technical field
The utility model relates to a kind of appliance switch, especially a kind of drive unit of three-stations load switch.
Technical background
Three-stations load switch is that dynamical element drives mainly with cylindrical spring at present, switch combined floodgate sub-switching operation and ground connection operation are to share a spring, this spring will be born and close, the dual load of sub-switching operation and ground connection operation, so that switch is not when reaching guideline lives, fatigue phenomenon has appearred in spring, movement velocity obviously reduces, mechanical property is not up to standard, and the driving device structure of this type of switch is complicated, parts are more, be difficult for assembling, any one damage parts of transferring power needs the integral replacing drive unit.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of drive unit of three-stations load switch, guarantees to improve its useful life.
The technical solution adopted in the utility model: a kind of drive unit of three-stations load switch, comprise buck plate and connecting rod, a side is provided with power shaft A on buck plate, power shaft A one end is equipped with input connecting lever A and interlock connecting lever A, input connecting lever A connects spring guide A, at spring guide A spring A is set, is connected with fulcrum bar of the spring A at spring guide A one end; Opposite side is provided with power shaft B on buck plate, and the upper end of power shaft B is equipped with input connecting lever B and interlock connecting lever B, and input connecting lever B connects spring guide B, and B arranges spring B at spring guide, is connected with fulcrum bar of the spring B at spring guide B one end; Connecting rod one end connects interlock connecting lever A, and the connecting rod other end connects interlock connecting lever B.
The drive unit of the utility model and former three-stations load switch is compared, the part kind reduces, volume is smaller and more exquisite, in appearance, this structure is more succinct, compact, when adopting said apparatus to carry out the contact of earth of appliance switch or ground connection separating brake, only needs clockwise or rotate counterclockwise power shaft A, just can finish contact of earth or ground connection separating brake, work at this process medi-spring A; When carrying out the load combined floodgate of appliance switch or loading separating brake, only need clockwise or rotate counterclockwise power shaft B, just can finish contact of earth or ground connection separating brake, work at this process medi-spring B, ground connection operation and load closing operation have independent spring, the mechanical fatigue problem of avoiding a spring multi-pass operation to bring.
Description of drawings
Fig. 1 is the driving device structure schematic diagram of former three-stations load switch;
Fig. 2 is the utility model structural representation;
In the accompanying drawing: 1 input connecting lever A, 2 power shaft A, 3 spring A, 4 spring guide A, 5 fulcrum bar of the spring A
6 connecting rods, 7 interlock connecting lever A, 8 input connecting lever B, 9 power shaft B, 10 interlock connecting lever B, 11 spring guide B, 12 spring B, 13 fulcrum bar of the spring B, 14 buck plates.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the driving device structure of former three-stations load switch is complicated, Assembly part is many, ground connection operation and load closing operation share a spring, in this device, the useful life of spring is shorter than the useful life of other parts, causes this apparatus parts Life Design not mate, and whole assembly difficulty is also larger.
As shown in Figure 2, a side is provided with power shaft A2 on buck plate 14, power shaft A2 one end is equipped with input connecting lever A1 and interlock connecting lever A7, the other end also is equipped with switch knob on power shaft A2, input connecting lever A1 connects spring guide A4, at spring guide A4 spring A 3 is set, is connected with fulcrum bar of the spring A5 at spring guide A4 one end; When the switch knob that clockwise rotates on the power shaft A2, drive input connecting lever A1 rotation, promote spring guide A4 and rotate around fulcrum bar of the spring A5; Compress Spring A3 energy storage, A3 is compressed to the dead-centre position when spring, and moment releases energy automatically, thereby is grounded combined floodgate; Opposite side is provided with power shaft B9 on buck plate 14, the upper end of power shaft B9 is equipped with input connecting lever B8 and interlock connecting lever B10, the other end also is equipped with switch knob on power shaft B9, input connecting lever B8 connects spring guide B11, at spring guide B11 spring B 12 is set, is connected with fulcrum bar of the spring B13 at spring guide B11 one end; Connecting rod 6 one ends connect interlock connecting lever A7, connecting rod 6 other ends connect interlock connecting lever B10, and this device medi-spring is Compress Spring all, when the switch knob that clockwise rotates on the power shaft B9, drive input connecting lever B8 rotation, promote spring guide B11 and rotate around fulcrum bar of the spring B13; Compress Spring B12 energy storage, when spring B 3 is compressed to the dead-centre position, moment releases energy automatically, thereby realizes that on-load switch closes a floodgate.
