Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
embodiment 1:as shown in Figures 1 to 3, goal of the invention of the present utility model is to overcome the problem that being subject to of adopting photo-electronic directly reading mode the to cause installation process tongue tube that ambient light conditions impact or tongue tube induction reading mode cause easily breaks, a kind of angle rotated by measuring character wheel is adopted to obtain the direct access mode of character wheel reading: for prior art Problems existing, to provide a kind of.
To achieve these goals, the technical solution adopted in the utility model is: a kind of magnetic strength character wheel for character wheel counter, comprises,
Character wheel body 1, the circumferential edges of a side of described character wheel body 1 is evenly equipped with a circle stepping and dashes forward tooth; Described stepping tooth 4 of dashing forward makes described character wheel rotate for receiving the outside power that transmits; The circumferential edges place of opposite side is provided with carry and dashes forward tooth 5, the circumference side of character wheel body 1 is divided into 0 ~ 90 digit position, namely each digit position takies character wheel circumference 36 degree of radian sizes, each position can be selected display label or not show label, do not show label to refer to, only to determine in ten positions divided equally that one is after 0, determines each digit position according to character wheel choosing dress direction order, but not by numerical reference on character wheel.
Character wheel axis body 2, is arranged on described character wheel body 1 circle centre position and vertical with described character wheel body 1, and described character wheel axis body 2 length is greater than the thickness of described character wheel body 1 and stretches out to described character wheel body 1 both sides;
Circular magnetic steel 3, is embedded in described character wheel body 1 side and coaxial with described character wheel body 1.Described circular magnetic steel 3 and described character wheel body, for being fixedly connected with, therefore just can rotate with described character wheel.
Further, described circular magnetic steel 3 is bipolarity radial magnetizing ring alnico.
Described circular magnetic steel 3 diameter of section is 9.02mm to 9.06mm.
During use, on described character wheel is placed on as shown in Figure 4 bracing frame by character wheel axis body 2, (support frame as described above comprises base 63, bracing frame 1 and bracing frame 2 62; Support frame as described above 1 and bracing frame 2 62 are provided with the semi-circular recesses 611,621 agreed with described character wheel axis body 2 size, shape.Described character wheel is by rotating described character wheel axis body 2 in described semi-circular recesses 611,621), described character wheel by described stepping dash forward tooth accept rotating force rotate, be arranged in parallel in any side of described character wheel angle detection device, as angular transducer (has another name called magnetic coder, as chip MMA253F), when described character wheel rotates, described circular magnetic steel 3 is rotated with described character wheel, described angular transducer obtains the angle of described character wheel rotation according to the changes of magnetic field of described circular magnetic steel 3, thus obtains the current reading of described character wheel; Because the angle sensing sensitivity of angular transducer to circular magnetic steel 3 is high, the rotation once of described circular magnetic steel 3 can be recorded in theory, and in fact on character wheel ten numerals be corresponding 36 degree of radians, therefore the character wheel adopting the utility model to provide, can provide the measurement result that precision is higher.
In some specific embodiments, conveniently install, described angular transducer is arranged on collection plate, and described collection plate can be plugged on the circuit board at processor (being responsible for the angle conversion that each character wheel rotates being numeral and output display) place.
In actual use, usually be all adopt the mode of character wheel group (also can individual character wheel be used alone) to count character wheel, therefore usual magnetic shielding cover is set between character wheel and character wheel, to prevent the magnetic force between different character wheel from interfering with each other, now carry out coordinating with described carry gear carry out carry transmission by described carry tooth, stepping tooth of dashing forward of dashing forward between adjacent character wheel.
Identical with the character wheel in most prior art, the part of character wheel described in the present embodiment except described annular magnetic steel 3 makes by not possessing ferromagnetic material, e.g., can be but be not limited to plastics.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
