Abstract

The utility model relates to a three-pointer electronic pulse counter, belonging to the category of a calculation meter. The utility model comprises three components of a step motor, a driving wheel system and an indication mechanism. The utility model is characterized in that the indication mechanism adds up the times of electric pulses by the excitation of the outer electric pulses. The energy of each electric pulse is transferred to the indication machine by the step motor via the driving wheel system. The indication mechanism is divided into a ten bit pointer, a hundred-thousand bit pointer and a ten-thousand-hundred-thousand bit pointer. The carry relationship of the utility model is a hundred bit relationship so as to make the calculation range of the three-pointer counter enlarge to the range from 0 to 99999. Thus the three-pointer electronic pulse counter has simple structure and concise and precise indication, and under the general condition the sizes of the pointers and a dial plate can be altered in order to be suitable for the requests of sizes of different sites. Furthermore the inner part of the three-pointer electronic pulse counter is not necessary to have power supply.

Description

Three-pointer electronic pulse counter

The utility model belongs to metering field.

Counting is an important business accounting index, also is the foundation that guarantees the time-based maintenance of machine operate as normal.At present counter mostly is mechanical type digital counter and electronic digital display counter, but certain weak point is all arranged: the mechanical type digital counter normally imports counter by machine power into by flexible axle makes its work, and promptly heaviness is very easily damaged again.Though electronic digital display counter commonly used has overcome this shortcoming of mechanical type digital counter, but typically use light emitting diode or LCDs, the display part circuit is very complicated, needs the power supply power supply, reliability is relatively poor, and its data of back are lost immediately cutting off the electricity supply.

The purpose of this utility model is: design a kind of electric impulse counter that overcomes above-mentioned defective.

The three hand electric impulse counter comprises stepper motor, train, indicating mechanism's three parts, it is characterized in that gear and rotor third wheel on the stepping motor rotor link, ten gears on a rotor third wheel and the ten bit pointer axle link, individual ten gears link by hundred kilobit gears on 1,000 third wheels and the hundred kilobit needle pivots, and hundred kilobit gears link by 10,010 myriabit gears on ten million third wheel and the 10010 myriabit needle pivots.

Feature of the present utility model is that described electric impulse counter display mode their the carry relation that is that three pointers indicate (referring to Fig. 4 .) is hundred relation.Electric pulse is by gear train assembly the energy of electric pulse to be passed to indicating mechanism through stepping motor rotor.

(referring to Fig. 1 .2.3.)

Embodiment:

Fig. 1. be mechanism of the present utility model face diagrammatic sketch

Fig. 2. be the watch face diagrammatic sketch

Fig. 3. be the side diagrammatic sketch

Fig. 4. be the dial plate diagrammatic sketch

Fig. 3. in 01 be ten bit pointers, 0,200 kilobit pointers, 030,000 ten myriabit pointers

06,000 ten thousand third wheels of 04 dial plate, 050,000 ten myriabit gears

0,700 kilobit gears 08 are crossed 090 hundred third wheels of wheel support

11 ten gears, 12 stepper motor stators of 10 stepping motor rotors

13 rotor third wheels, 14 stepping motor rotor gears

By Fig. 3. shown in, when electric pulse drive stepping motor rotor, make it rotate 180 °, this moment, it was for nutating gear system and indicating mechanism, at Fig. 4. in will be expressed as ten bit pointer and clockwise rotate little lattice.Ten bit pointer will clockwise rotate a week after 100 pulses are imported into, hundred kilobit pointers will rotate little lattice, with should 10,000 pulses import back ten bit pointer into and will change for 100 weeks, hundred kilobit pointers rotate a week, 10,010 myriabit pointers will rotate little lattice, represent the output of a workpiece finished product like this as each electric pulse, pointer index will be the sum of workpiece product output on the dial plate so.

The utility model is simple and reliable for structure, uses intuitive and convenient, need not the independent current source power supply.The panel board that is specially adapted to the electronic surveying counting shows, can not make loss of data because of power circuit damages.
