Problems solved by technology

Although the method of inlaying transparent materials can make up for the problem of air bubbles caused by the light-transmitting holes, its production and processing are more complicated, and there are also problems of easy deformation after demoulding, high defective rate, and the gap between the transparent material and the light-transmitting holes. It is also difficult to match
In addition, although the problem of center of gravity offset is compensated to a certain extent by filling transparent materials, after all, due to the different material densities, the problem of center of gravity offset cannot be completely overcome, and there are still troubles in installation

Embodiment 1

[0027] Embodiment one: see figure 1 , figure 2 , image 3 , Figure 4 , the number 1 in the figure is the character wheel body, 2a and 2b are the bosses on both sides of the character wheel respectively, the surface of the boss is a pure plane structure, 3 is the opaque coating, 4 is the light-transmitting area, and 5 is the surface of the character wheel On the cylindrical side, 6 is a digital code, 7 is a stepping protrusion, 8 is a carry protrusion, and 9 is a central shaft hole.

[0028] In the code wheel of the counter and the water meter in this embodiment, the body of the wheel is made of transparent material, such as transparent engineering plastics or plexiglass lamp material to make the body of the wheel fully transparent or translucent. The whole character wheel is a light-transmitting character wheel like this, that is, the light signal sent from one side of the character wheel should be received at the other side. Then a layer of different light coating is co...

Embodiment 2

[0031] Embodiment two: still refer to figure 1 , figure 2 , image 3 , Figure 4 , the content and labels are the same as those in Embodiment 1, the slight difference is that: the two sides of the character wheel body are pure plane structures. The purpose of this design is to prevent the possibility of air bubbles accumulating on the side.

Embodiment 3

[0032] Embodiment 3: The accompanying drawings are not drawn, and the content is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that a step ring slightly higher than the side is provided around the center axis hole of the character wheel at the same time. In order to prevent the direct contact between the side of the character wheel and both sides and wear the opaque coating.

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

1. Technical field: [0001] The invention relates to an improved counter character wheel and water meter, in particular to a counter code character wheel and water meter. 2. Background technology: [0002] At present, the water meter usually connects the coding character wheels in series on the rotating shaft to represent ones, tens, etc., and the cylindrical side of each character wheel is printed with ten numbers from 0 to 9, respectively, and a carry wheel is installed between each character wheel. , and cooperate with the transmission mechanism to realize counting. However, the water meter counter coding wheel and the water meter will not only meet the needs of people's visual reading, but also be suitable for the needs of electronic automatic counting. There are various ways of counting through character wheels, and the typical ones are counting through reflection and light transmission. Among them, the counting through the light transmission method is that sampling pl...
