Abstract
The invention provides a diameter measuring gauge. The diameter measuring gauge comprises a transparent gauge plate, wherein two orthogonal scale axes are arranged on the transparent gauge plate, each scale axis has an original point and two positive half axes symmetrically extending to the two sides from the original point, and the two scale axes are orthogonal on the original points. The diameter of a geometrical circle on paper can be accurately measured at a high speed by the diameter measuring gauge.
Description
Technical field
The present invention relates to stationery field, especially, relate to a kind of gage.
Background technology
At present, for circular diameter, common available folder chi is measured, but this kind of folder chi all has movable part, and typical case is as vernier caliper; Its structure bulky complex, although very convenient to the measurement of workpiece, for paper figure, it is very inconvenient to measure, and especially for student, wish is measured how much circular diameters on paper, and the practicality that adopts folder chi to measure is poor.And in addition, do not have a kind of can Quick Measurement paper the gages of how much circles, make outside construction with ruler and compasses, have no idea accurately to obtain how much diameter of a circles.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of diameter gage, this diameter gage speed faster, measures how much diameter of a circles of a paper exactly.
The technical solution adopted for the present invention to solve the technical problems is: this diameter gage comprises transparent ruler plate; On described transparent ruler plate, have two mutually orthogonal scale axles, each described scale axle has an initial point, and two positive axis of extending from this initial point to symmetria bilateralis; Article two, described scale axle is orthogonal to initial point.
As preferably, on a scale axle wherein, be shaped with a setting-out groove extending along scale axle.
As preferably, described transparent ruler plate is circular slab.
As preferably, a scale axle is wherein produced on a bar shaped slide plate on described transparent ruler plate; Described bar shaped slide plate can be free to slide along the bearing of trend of the scale axle on bar shaped slide plate on described transparent ruler plate surface.
Beneficial effect of the present invention is: this diameter gage is being measured how much bowlders of paper, only need choose a suitable scale on arbitrary scale axle, be fixed on any point P on round week how much, then rotate transparent ruler plate taking P as the center of circle, make on this scale axle, with a scale of P point place scale value symmetry, also fall within how much round weeks upper, be designated as Q point; Now this geometry diameter of a circle equals, the corresponding scale value sum of two intersection points in another scale axle and this round week of geometry.
Brief description of the drawings
Fig. 1 is embodiment mono-schematic diagram of this diameter gage.
Fig. 2 is the schematic diagram of embodiment mono-in the time of measure geometry circular diameter.
Fig. 3 is the first view of this diameter gage embodiment bis-.
Fig. 4 is the second view of this diameter gage embodiment bis-.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
Embodiment mono-:
Figure 1 shows that the embodiment mono-of this diameter gage, this diameter gage comprises circular transparent ruler plate 1; On described transparent ruler plate 1, have two mutually orthogonal scale axles 11,12, each described scale axle has an initial point, and two positive axis of extending from this initial point to symmetria bilateralis; Article two, described scale axle is orthogonal to initial point.
In Fig. 1, initial point be labeled as 0, two scale axle 11,12 initial point both sides scale value be farthest labeled as N(due to the present embodiment in, two scale axles are isometric), and omitted remaining scale mark.
On a scale axle 12 wherein, be shaped with a setting-out groove 13 extending along scale axle, so that in the time measuring diameter, available paintbrush directly draws diameter.
Above-mentioned diameter gage is being measured how much bowlders of paper, as shown in Figure 2, choose a suitable scale on scale axle 11, be fixed on any point P on circle C circumference how much, then rotate transparent ruler plate 1 taking P as the center of circle, make on this scale axle 11, with a scale of P point place scale value symmetry, also fall within how much and justify on C circumference, be designated as Q point; Now the diameter of this geometry circle C equals, the corresponding scale value sum of two intersection point J, K of scale axle 12 and this geometry circle C circumference.Its theoretical foundation is: the perpendicular bisector of any string of how much circles, must overlap with this geometry diameter of a circle; Therefore, formed a string of how much circle C by P, 2 of Q, perpendicular bisectors of this string due to scale axle 12, therefore, scale axle 12 is now just on the diameter of how much circle C, therefore, the corresponding scale value sum of two intersection point J, K of scale axle 12 and this geometry circle C circumference is the diameter of this geometry circle C.
Embodiment bis-:
Fig. 3, Figure 4 shows that the embodiment bis-of this diameter gage, it has omitted setting-out groove; In addition, be with the main difference part of embodiment mono-: scale axle 12 is produced on a bar shaped slide plate 10 on described transparent ruler plate 1; Described bar shaped slide plate 10 can be free to slide along the bearing of trend of the scale axle 12 on bar shaped slide plate on described transparent ruler plate 1 surface; When concrete making, only need on transparent ruler plate 1, make a chute 100, then described bar shaped slide plate 10 is embedded in this chute 100, in order to keep the surface finishing of whole transparent ruler plate 1, make the thickness of described bar shaped slide plate 10 equal the degree of depth of chute 100, can make upper surface and the flush of transparent ruler plate 1 outside bar shaped slide plate 10 of bar shaped slide plate 10.
The remarkable advantage of embodiment bis-is: in the time of measure geometry diameter of a circle, first bar shaped slide plate 10 is playbacked to the state shown in Fig. 3, that is, the initial point of two scale axles 11,12 is overlapped; Then obtain diameter of a circle how much according to the mode of embodiment mono-, then, promote described bar shaped slide plate 10, the initial point of the scale axle 12 on this bar shaped slide plate 10 is fallen within on the circumference of how much circles, scale axle 12 and the multipair scale values of answering of intersection point how much circles, except initial point, be this geometry diameter of a circle numerical value; Visible, embodiment bis-can omit the calculation procedure in embodiment mono-measuring process completely.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
