Abstract
The utility model discloses an unsmooth type instrument measurement code code wheel, including code wheel hub (1) that the code wheel was personally experienced sth. Part of the body (2) and was linked to each other with the code wheel body, the code wheel body is gone up and is equipped with 3 printing opacity breachs altogether along circumference: first printing opacity breach (3), second printing opacity breach (4) and third printing opacity breach (5), relative with third printing opacity breach with first printing opacity breach, second printing opacity breach respectively on the code wheel body is first lug (7), second lug (8) and third lug (9), two wantonly printing opacity breachs for the central angle in the disc body centre of a circle inequality. This unsmooth type instrument measurement code code wheel simple structure, easy to carry out, the accurate reading of being convenient for.
Description
Technical field
The utility model relates to a kind of concave-convex type metering instrument coding code-disc.
Background technology
The photoelectricity identification character wheel adopted in photo-electronic directly reading coding measuring instrument at present utilizes reflective and transmission-type all to have, and wherein reflective processing request is high and reliability is not high; The volume of transmission-type is large, not easily processes, and during mounting cost, 0 and 9 carry identification difficulties, can only be accurate to 1(as side's water), identify and sometimes can produce the shortcoming misread.Therefore, a kind of novel concave-convex type metering instrument coding of design code-disc is necessary.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of concave-convex type metering instrument coding code-disc, and this concave-convex type metering instrument coding code-disc structure is simple, easy to implement, is convenient to pin-point reading.
The technical solution of utility model is as follows:
A kind of concave-convex type metering instrument coding code-disc, the code-disc hub (1) comprising code-disc body (2) and be connected with code-disc body; Code-disc body is circumferentially provided with 3 printing opacity breach altogether: the first printing opacity breach (3), the second printing opacity breach (4) and the 3rd printing opacity breach (5); Relative with the 3rd printing opacity breach with the first printing opacity breach, the second printing opacity breach respectively on code-disc body is the first lug (7), the second lug (8) and the 3rd lug (9); Any two printing opacity breach relative to the central angle in the disc center of circle not identical.
The first described printing opacity breach, the second printing opacity breach and the 3rd printing opacity breach relative to the central angle in the disc center of circle be respectively 90 °, 27 ° and 63 °.
First lug, the second lug and the 3rd lug relative to the central angle in the disc center of circle be respectively 90 °, 27 ° and 63 °.
Code-disc hub is provided with hub axis hole (6).Concave-convex type metering instrument coding code-disc can be fixed on gear set axle center by hub axis hole.
Printing opacity breach can replace by reflecting piece, namely need not arrange printing opacity breach.
Code-disc body, code-disc hub are black ABS material plastic parts.Printing opacity breach is circular arc, rectangle, square or trapezoidal.Code-disc body thickness is 1mm ± 0.5mm.
The utility model adopts brand-new code-disc decoding technique, and thoroughly solve 0 and 9 carry identification difficulties, during for water meter, degree of accuracy reaches 0.1 cube even 0.01 cube, for water meter measurement circle promotes again a height.The utility model can coding code-disc on measuring instrument inside counting device or character wheel.
Due to each numeral and carry gear and circular arc printing opacity hole slot or reflecting piece corresponding, code-disc rotates a circle, there is the difference on electric signal at printing opacity hole slot and alternatively non-transparent hole slot due to optoelectronic induction device, the optoelectronic induction device being arranged on code-disc both sides can produce 32 groups of different codings and differentiate, thus reaches the accurate of electronical reading.
The utility model concave-convex type photoelectric coding measuring instrument code-disc or character wheel outer ring and inner ring corresponding optoelectronic induction device respectively, can form 32 group codings, this digitally encoded signal can be directly inputted to integrated electronic modules reliable recognition reading.
Beneficial effect:
Concave-convex type metering instrument coding code-disc of the present utility model, coding number when 1 ~ 9 carry increasing to the stop of light signal by code-disc light hole with the code-disc body except code-disc light hole, the uncertain state of release critical zone, thus drastically increase the accuracy of photoelectric coding measuring instrument reading, and it is little to have volume, practical, the advantage of long service life, implementation method simple possible, reduce manufacturing technique requirent, the utility model can be widely used in the counter of photoelectricity recognition technology, is applicable to batch production.
