Abstract

The utility model discloses a resistor type number wheel, which comprises a wheel body, digital signs on the column surface of the wheel body, and a driving column at the wheel body side. The utility model is characterized in that a plurality of equivalent resistances corresponding to the digital signs are arranged in the wheel body, the resistors are connected in series according to the changing order of the digital signs, and each resistor is provided with a measuring terminal. The numer wheel has the advantages of accurate and easy store data read, reliable operation and low cost, and the utility model has no power source, so the utility model is easy to do remote data transmission.

Description

A kind of resistance-type number wheel

The utility model relates to the count number wheel that measures usefulness.

The count number wheel is widely used in various several wheel type counters, on instrument such as water meter, ammeter, gas meter.Traditional number wheel only has the function of mechanical display digit symbol, can only be during data on people's acquisition instrument by soon, write by hand, although number wheel like this is easy to people and observes and read, often low, the accuracy of inefficiency, data user rate is subject to the human factor influence, and copy reading labour intensity is big.At present, people design another kind of counter, on traditional number wheel instrument, set up some sensors or parameter concentrator, by lead, power supply with these data storages or long-distance transmissions, the work efficiency of checking meter, reading is greatly improved, but in the actual application, because parts working environments such as sensor, data concentrator, LCD are had relatively high expectations, complex structure, cost height, the popularization resistance is big, more main is that these electron devices all be unable to do without power supply, cause that instrument is too complicated, failure rate is high, use inconvenient.

The purpose of this utility model is the weak point that overcomes above-mentioned prior art, provides a kind of own passive, reads and stores data easily, accurately, and cost is low, the resistance-type number wheel that reliability is high.

The purpose of this utility model is achieved by the following technical solution: a kind of resistance-type number wheel, include taking off post of digit on wheel body, the wheel body face of cylinder, wheel body side surface, it is characterized in that: a plurality of substitutional resistances corresponding with digit are housed in the wheel body, each resistance is connected in series in proper order by the variation of digit, and each resistance all has the measurement exit.Further, the resistance measurement exit adopts contact and slide rail to be slidingly matched, it is external that wheel is fixed in the contact, slide rail then is arranged on the wheel body face of cylinder, wherein a slide rail is that multistage is interrupted slide rail, every intersegmental disconnected slide rail only is connected conducting with a resistance, and another slide rail is continuous slide rail, is connected conducting with the starting point of resistance in series.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are further elaborated.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic side view of Fig. 1;

Fig. 3 is the expansion synoptic diagram of Fig. 1 periphery.

Referring to Fig. 1-Fig. 3, present embodiment includes the wheel body 1 of traditional number wheel, be distributed in ten digits of " 0-9 " on wheel body 1 face of cylinder, wheel body 1 side is used for taking off post 2 with other number wheel accumulative total carries are used, with other difference is the wheel body 1 interior corresponding groove 3 that has, be packaged with ten substitutional resistances corresponding 4 in the groove 3 with digit, each resistance 4 is connected in series, and it is corresponding with digit " 1 " by first resistance, second resistance of serial connection is corresponding with digit " 2 ", the 3rd resistance of serial connection is corresponding with digit " 3 " ... being connected in series the last resistance mode corresponding with digital " 0 " connects.The side of the digit on the wheel body face of cylinder is provided with two parallel sliding tracks, and one is to be separated into ten sections interruption slide rail 5, and another is continuous slide rail 6, and each compartmented that is interrupted slide rail 5 is corresponding to be connected conducting with a resistance 4.And the

outer contact

7,8 that is provided with of number wheel, cooperate with 5,6 sliding contacts of two slide rails respectively, when number wheel rotation work,

contact

7,8 is rubbing contact on slide rail 5,6 respectively, when contact 7 rests on when being interrupted on the slide rail 5, the numerical value of its locational digit is corresponding with resistance in series resistance in circuit value, contact 7 on different interruption slide rail 5 positions just to different resistance values should be arranged, by measuring the resistance value of two contacts, 7,8 ends, just can corresponding draw the numerical value of the expression of number wheel.Like this, people on the one hand can observe reading numerical values by the digit on the number wheel, also can measure corresponding resistance value at the measuring junction of number wheel by resistance apparatus on the other hand, with data storage in instrument.

In sum, the utlity model has obvious advantage:

1, resistance-type structure, number wheel itself is passive, and structure is greatly simplified;

2, can by electronic instrument with data resistance value electronization, realize teletransmission, Store;

3, stable performance, reliable operation;

4, Costco Wholesale is low, is easy to produce and promote.

Claims

1, a kind of resistance-type number wheel, include taking off post of digit on wheel body, the wheel body face of cylinder, wheel body side surface, it is characterized in that: a plurality of substitutional resistances corresponding with digit are housed in the wheel body, and each resistance is connected in series in proper order by the variation of digit, and each resistance all has the measurement exit.

2, number wheel according to claim 1, it is characterized in that the resistance measurement exit adopts contact and slide rail to be slidingly matched, it is external that wheel is fixed in the contact, slide rail then is arranged on the wheel body face of cylinder, wherein a slide rail is that multistage is interrupted slide rail, every intersegmental disconnected slide rail only is connected conducting with a resistance, and another slide rail is continuous slide rail, is connected conducting with the starting point of resistance in series.
