Abstract
This invention relates to a counter coded character wheel and a water meter, wherein the counter coded character wheel comprises a character wheel body and a shaft hole or shaft which is arranged in the center of the character wheel body, a circle of stepping projecting teeth are evenly distributed on the peripheral border of one side of the character wheel body, stepping projecting teeth are distributed on the peripheral border of the other side of the character wheel body, and ten digital labeling numbers from 0 to 9 are evenly distributed on the peripheral side of the character wheel body. The counter coded character wheel is characterized in that the character wheel body is totally made of a transparent material; and a light-proof material layer is coated on one side of the transparent character wheel body to form at least one sector transparent area or at least one ring sector transparent strip. In the invention, the coded character wheel of the water meter is improved to overcome the problem that the original character wheel is easy to gather bubbles and can generate gravity shift, therefore, the character wheel can not rotate randomly when in installation, moreover, the installation speed is fast, and the production efficiency is high, thus being very conducive to the polarization and implementation.
Description
One, technical field:
The present invention relates to a kind of improved counter character wheel and water meter, particularly relate to a kind of coding print wheel of counter and water meter.
Two, background technology:
Water meter normally is connected on coding print wheel and represents individual, ten in the rotating shaft successively at present ..., the cylindrical side of each character wheel is printed on 0～90 numeral number again respectively, is separately installed with rounding wheel between each character wheel, and cooperates gear train to realize counting.Yet water meter counter coding print wheel and water meter not only will satisfy people's vision reading needs, count needs automatically but also will be fit to electronics.Existing mode through the character wheel counting is various, relatively is typically through reflective and counts with the printing opacity mode.What wherein count through the printing opacity mode is between each coding print wheel, to be separately installed with sampling plate; Be respectively equipped with infrared emission tube group and receiving tube group on the both sides neighbouring sample plate of arbitrary character wheel; Through light hole or light tank are set, carry out decimal coded and counting according to the amount of light that transmits and receives on the coding print wheel side.The various coding print wheel kinds that design to this counting principle are more.Yet, existing printing opacity character wheel, its photic zone is generally through hole, and for example the patent No. is 200620033842.8 utility model patent " direct reading encoder counter ", on coding print wheel, is provided with the arc light tank exactly.Though this structure can realize printing opacity counting, this be provided with the character wheel of hole light groove and be not easy make, common problem is an easy deformation after the demoulding, defect rate is high, and in use because off-centring, causes being not easy to zeroing when installing and operating.The distortion situation in use also appears in addition easily.More distinct issues are, often assemble bubble easily in the light hole of this character wheel and reflect, and according to the ray cast principle, small bubble just might cause bigger projection error, so the phenomenon that electronical reading is forbidden appears in this character wheel easily.Based on the deficiency of this character wheel technology, No. 200820147211.8 utility model patents " coding print wheel of counter and water meter " have carried out the explanation of improvement property for the 6th page the 1st section at instructions, are about to the convex oolemma and are embedded in the character wheel hole.Though the mode through inlaying transparent material can remedy the air bubble problem that produces because of light hole, its making and processing are complicated more, exist the demoulding yielding equally, the problem that defect rate is high, and the coupling between transparent material and the light hole also has certain difficulty.In addition, though remedied the centre-of gravity shift problem to a certain extent through filling transparent material, because of material density is different, the centre-of gravity shift problem can not overcome fully after all, still has the trouble of installing.
Three, summary of the invention:
The present invention overcomes the deficiency that prior art exists, and provides a kind of and can not produce bubble, the coding print wheel of counter of making and installing easily and water meter.
