The utility model discloses a circular hole type encoded character wheel on a counter in a meter. By the circular hole type encoded character wheel, the accuracy is high, and the production process is simple and feasible. According to the circular hole type encoded character wheel, ten numbers, namely 0 to 9 are formed on each encoded character wheel, and a first arc light transmission hole groove, a second arc light transmission hole groove, a third arc light transmission hole groove and a circular light transmission hole groove are formed on the spoke of each encoded character wheel. By the circular hole type encoded character wheel, the accuracy of electronic reading is improved, an implementation method is simple and feasible, and requirements on the production process is reduced; and the circular hole type encoded character wheel is suitable for batch manufacturing and applicable to meters, particularly water meters, gas meters and electricity meters.
Description
Technical field
The utility model relates to a kind of gauging table, in particular, relates to the circular hole coding print wheel on a kind of counter in meter.
Background technology
In the prior art, the principle of photo-electronic directly reading gauging table is by reflection or the optical texture of transmission are set at character wheel, and when character wheel rotated, the light of transmission or reflection was to optoelectronic induction plate transmission of signal, and then form the number change that each character wheel rotates, be transferred in the electronic computing system; Coding print wheel utilizes two kinds of reflective and transmission-types.Wherein reflective character wheel processing request is high and reliability is not high; The useful individual pen of transmission-type and two circle flutings, still do not adopt round hole slot to exist by the coded system that the coding that increases critical localisation solves 09 carry problem at present.
Summary of the invention
Technical purpose of the present utility model is to overcome in the prior art, and the counter in meter coding print wheel of photoelectric direct-reading exists poor accuracy, technical matters that reliability is low; Circular hole coding print wheel on the simple and easy to do counter in meter of a kind of pin-point accuracy and manufacturing technique requirent is provided.
For realizing above technical purpose, the technical solution of the utility model is:
Circular hole coding print wheel on the counter in meter, described each coding print wheel are provided with 0～90 numeral; It is characterized in that: the spoke of coding print wheel is provided with the first circular arc printing opacity hole slot, the second circular arc printing opacity hole slot, three-arc printing opacity hole slot and circular printing opacity hole slot.
Further, the central angle of described the first circular arc printing opacity hole slot is 20 ° to 40 ° unspecified angle;
Further, the central angle of described the second circular arc printing opacity hole slot is 90 °;
Further, the central angle of described three-arc printing opacity hole slot is the same complementary angle of the first circular arc printing opacity hole slot central angle, namely from 50 ° to 70 °.
Further, described circular printing opacity hole slot is located between three-arc printing opacity hole slot and the coding print wheel center of circle, and described circular printing opacity hole slot is located at the numeral 3 of coding print wheel and the position between the numeral 4.
The edge of all printing opacity hole slots is provided with step on the spoke of coding print wheel, makes the light that passes the printing opacity hole slot keep straight line to arrive an other side.Because each numeral is corresponding with carry tooth and circular arc or round printing opacity hole slot, character wheel rotates a circle, and the optoelectronic induction device that is installed in the character wheel both sides can produce the digital signal supplied for electronic unit identification of 31 groups of different codings and read, and the realization electronical reading is accurate.Round printing opacity hole slot can be given birth to one or more intermediate codes by fecund, and character wheel is used as the location when press figure and assembling.
Useful technique effect of the present utility model is: adopt a kind of brand-new round hole slot mode to solve the coded system of 09 carry problem.And with individual pen mode of the prior art and two the two efficient coding that organically combines of circle mode.Coding number when increasing by 09 carry by circular printing opacity hole slot discharges the uncertain state of critical zone, thereby has greatly improved the electronical reading accuracy, and the implementation method simple possible, has reduced the requirement of production technology, is fit to batch making.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of single circular hole coding print wheel among embodiment of the utility model.
Embodiment
In conjunction with Fig. 1 and Fig. 2, describe embodiment of the present utility model in detail, but claim is not done any restriction.
In the structure of the circular hole coding print wheel on the utility model counter in meter, each coding print wheel is provided with 0～90 numeral; The spoke of coding print wheel is provided with the first circular arc printing opacity hole slot 1, the second circular arc printing opacity hole slot 2, three-arc printing opacity hole slot 3 and circular printing opacity hole slot 4.The central angle of the first circular arc printing opacity hole slot 1 is 20 ° to 40 ° unspecified angle, is 30 ° during enforcement; The central angle of the second circular arc printing opacity hole slot 2 is 90 °; The central angle of three-arc printing opacity hole slot 3 is the same complementary angle of the first circular arc printing opacity hole slot 1 central angle, namely from 50 ° to 70 °, during enforcement is 60 °.When implementing technical solutions of the utility model, circular printing opacity hole slot 4 is located between three-arc printing opacity hole slot 3 and the coding print wheel center of circle, and described circular printing opacity hole slot 4 is located at the numeral 3 of coding print wheel and the position between the numeral 4.The edge of the first circular arc printing opacity hole slot 1, the second circular arc printing opacity hole slot 2, three-arc printing opacity hole slot 3 and circular printing opacity hole slot 4 is provided with step, and the light 101 that light-emitting component 100 is sent can pass the printing opacity hole slot and keep straight line to arrive an other side.Because each numeral is corresponding with carry tooth and circular arc or round printing opacity hole slot, character wheel rotates a circle, and the optoelectronic induction device that is installed in the character wheel both sides can produce the digital signal supplied for electronic unit identification of 31 groups of different codings and read, and the realization electronical reading is accurate.Round printing opacity hole slot can be given birth to one or more intermediate codes by fecund, and character wheel is used as the location when press figure and assembling.
Coding number when increasing by 09 carry by circular printing opacity hole slot of the present utility model discharges the uncertain state of critical zone, thereby has greatly improved the electronical reading accuracy, is the not only practical but also novel technological improvement of one of this area.
