Abstract
The utility model discloses a kind of mapping arrangements, the ruler body of this mapping arrangements arranges circular hole slot, the picture circle that rotating shaft and more than one and the center of circle of the circular hole slot of ruler have a certain distance is fixed a point small sircle hole, utilize the angle index line of rotating shaft index line in rotating shaft and ruler circular port groove edge, more conveniently can carry out measurement and the drafting of angle line, utilize the picture circle fixed point small sircle hole on ruler simultaneously, ruler body and rotating shaft are rotated, simply can draw the circular arc of conventional diameter with circular, with the unitary system map device that simple ruler body and rotating shaft form, reach ruler, protractor, the required most function of the drawing such as compasses, solution need carry most inconvenient problem of planting traditional mapping arrangements and can implement to chart.
Description
Technical field
The utility model relates to a kind of mapping arrangements, particularly relates to a kind of mapping arrangements of ruler class.
Background technology
Known traditional mapping arrangements, ruler need be coordinated to draw straight line and measure distance, protractor measures and draws angle, compasses draw circular arc and circle etc., the conventional major cartographic function such as straight line, angle, circle of drawing just need can be reached with multiple mapping arrangements, because required mapping arrangements is various, not portable, take care of or produce because omitting a certain mapping arrangements the puzzlement of drawing inconvenience.
Utility model content
For solving the problems of the technologies described above, the utility model devises a kind of mapping arrangements of ruler class.
The utility model adopts following technical scheme:
A kind of mapping arrangements, comprise ruler body, ruler body has ruler graduation mark, ruler body is provided with the circular hole slot of ruler, at least one circular hole slot and a rotating shaft is provided with in the circular hole slot of ruler, rotating shaft can freely be rotated by opposing circular hole slot, and ruler body is at least provided with more than one the picture circle having a certain distance with the center of circle of the circular hole slot of ruler and fixes a point small sircle hole.
As preferably, described ruler body is positioned at the circular hole slot periphery of ruler and is provided with protractor graduation mark.
As preferably, the circle centre position of the circular hole slot of described ruler is provided with rotating shaft small sircle hole.
As preferably, described rotating shaft is provided with rotating shaft index line.
As preferably, described ruler body is provided with multiple figure hole, multiple figure hole is circular hole, elliptical aperture, equilateral triangle hole, square hole and diamond hole.
Compared with prior art, the ruler body of this mapping arrangements arranges circular hole slot, the picture circle that rotating shaft and more than one and the center of circle of the circular hole slot of ruler have a certain distance is fixed a point small sircle hole, utilize the angle index line of rotating shaft index line in rotating shaft and ruler circular port groove edge, more conveniently can carry out measurement and the drafting of angle line, utilize the picture circle fixed point small sircle hole on ruler simultaneously, ruler body and rotating shaft are rotated, simply can draw the circular arc of conventional diameter with circular, with the unitary system map device that simple ruler body and rotating shaft form, reach ruler, protractor, the required most function of the drawing such as compasses, solution need carry most inconvenient problem of planting traditional mapping arrangements and can implement to chart.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
In figure: 1, ruler body, 2, the circular hole slot of ruler, 3, draw circle fixed point small sircle hole, 4, protractor graduation mark, 5, ruler graduation mark, 6, rotating shaft, 7, rotating shaft index line, 8, rotating shaft small sircle hole, 9, figure hole.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically:
Embodiment: as shown in Figure 1, a kind of mapping arrangements, comprise ruler body 1, ruler body has ruler graduation mark 5, ruler body is provided with the circular hole slot 2 of ruler, at least one circular hole slot and a rotating shaft 6 is provided with in the circular hole slot of ruler, rotating shaft can freely be rotated by opposing circular hole slot, ruler body is at least provided with more than one the picture circle having a certain distance with the center of circle of the circular hole slot of ruler and fixes a point small sircle hole 3, ruler body is positioned at the circular hole slot periphery of ruler and is provided with protractor graduation mark 4, the circle centre position of the circular hole slot of ruler is provided with rotating shaft small sircle hole 8, rotating shaft is provided with rotating shaft index line 7, ruler body is provided with multiple figure hole 9, multiple figure hole is circular hole, elliptical aperture, equilateral triangle hole, square hole and diamond hole.
Use this mapping arrangements can realize drawing angle line, draw circle, draw the drawing functions such as circular arc.
Draw angle line: after rotating shaft index line and ruler protractor graduation mark being made zero, a straight line is first painted in ruler graduation mark side, then rotary ruler combination after fixed rotating shaft, after aligning to rotating shaft index line and the graduation mark for drawing angle, a straight line is separately painted below ruler protractor graduation mark, then can complete for drawing the angle line of angle, the angle line of various angle can be drawn according to this.
Draw circular: use hand fixed rotating shaft, after selecting the picture circle fixed point small sircle hole for drawing round diameter size, pen is placed in picture circle fixed point small sircle hole, the drafting of circle can be completed after rotary ruler combination circumference, with above step, drawing pin is placed in rotating shaft small sircle hole, after rotary ruler combination circumference, also can completes the drafting of circle.
Draw circular arc: after rotating shaft index line and ruler protractor graduation mark being made zero, use hand fixed rotating shaft, after selecting the picture circle fixed point small sircle hole for drawing arc diameter size, pen is placed in picture circle fixed point small sircle hole, after rotary ruler combination to rotating shaft index line and the graduation mark for drawing angle aligns, namely complete the circular arc for drawing angle.
Above-described embodiment is one of the present utility model preferably scheme, not does any pro forma restriction to the utility model, also has other variant and remodeling under the prerequisite not exceeding the technical scheme described in claim.
