Abstract
The utility model discloses a calculating disc for calculating contraception and procreation rules of women. The utility model is characterized in that the utility model is composed of a large disc and a small disc arranged on the same center rotating shaft on which the large disc is arranged, and the large disc and the small disc rotate correspondingly by the center rotating shaft. The large disc and the small disc are both equally divided into 31 parts along circumference, the center of the circumference and equally divided points of the circumference are connected, the surface of discs is equally divided into 31 grids, and each grid represents one day. Meanwhile, the 31 grids of the small disc, namely that 31 days are divided into 7 areas which respectively represent a catamenia period, a front safe period, a relatively safe period, a crisis period and a safe period. The small disc is also provided with 7 concentric circles to represent 7 kinds of menstrual cycles.
Description
The utility model relates to a kind of calculating dial that is used to calculate the women's physiological Changing Pattern, is contraception and growth regularity calculating dial that a kind of women uses specifically.
Do not see that in the market being useful on the apparatus that calculates the women's physiological Changing Pattern sells.
It is a kind of simple in structure that the purpose of this utility model is to provide, and portably uses the calculating dial that is used to calculate contraception of woman and growth regularity easily.
To achieve these goals, the utility model adopts following technical scheme: a kind of calculating dial that is used to calculate contraception of woman and growth regularity, it is characterized in that: it is made up of a big disk and the roundel that is arranged on the same central rotating shaft of big disk, and big roundel relatively rotates with central shaft.Big roundel connects the center of circle and circumference Along ent all along circumference 31 five equilibriums, and branch 31 lattice such as disks, every lattice are represented one day.31 lattice on the roundel are 7 zones of 31 natural gift simultaneously, represent menstrual period, preceding safe period, comparatively safe phase, critical days, safe period respectively.Also establish 7 concentric circless on the roundel, represent 7 kinds of menstrual cycles.
The utility model good effect is, the women is calculated understand own physiological change rule, instructs, grasps contraception and growth regularity.The utility model is simple in structure, uses convenience of calculation.
Below in conjunction with drawings and Examples the utility model is elaborated.
Accompanying drawing is the utility model structural representation.
As shown in the figure, the utility model is made up of a big disk 01 and the roundel 02 that is arranged on the same central rotating shaft P of big disk, and big roundel relatively rotates around same central rotating shaft.Big roundel connects the center of circle and circumference Along ent all along circumference 31 five equilibriums, and branch 31 lattice such as disks, every lattice are represented one day, represent one month 31 days.31 lattice on the roundel are 7 zones of 31 natural gift simultaneously, use different color showings respectively.Wherein represented the menstrual period in 5 of a1 to a5 days, represent with redness, and red length is elongated by weak point safe period before the expressions in 0-5 days of a6 to a10, represent with light green color, and light green length was represented to represent with yellowish green the comparatively safe phase by short elongated in 2 days of a11 to a12,10 days of a13 to a22 expression critical days, yellow expression is arranged, represented safe period, and represented in 9 days of a23 to a31 with dark green.Establish 7 concentric circless 31,30,29,28,27,26,25 on the roundel, represent 7 kinds of menstrual cycles.When the utility model uses, the menstrual cycle that at first will determine oneself is that is a kind of in 7 kinds, such as being 30 day one-period, rotate roundel then menstrual cycle fate 30 is aimed at the current date in the period first time in person of big disk, so the date on 5 regional alignment big disks on the roundel, just can judge the best opportunity of selecting oneself to practise contraception and give birth to.
