Detailed description of the invention
Below in conjunction with accompanying drawing 1 ~ 6, a kind of embodiment of the present utility model is further described.
A kind of multifunction double-layer chi, comprises two rulers and a connector.Two described rulers, it is lower, and chi 1 is placed in lower floor, upper chi 2 is placed in upper strata.Two rulers are all material with transparent plastic, and length is all 204mm, and width is all 20mm.
Described lower chi 1, as shown in Figure 1, the both sides up and down of lower chi 1 are all provided with distance scale.The wherein scale of top, the center 20mm that leaves a blank does not establish scale, and its both sides all from inside to outside, from 0 to 90mm indicate scale respectively; Following scale, to both sides, all indicate scale from 0 to 100mm respectively from center.At the center of lower chi, indicate an angular surveying baseline 1a, identify angle for when drawing or measured angular.Circular hole 1b is provided with again, for being inserted in connector 3 at the center of lower chi.
Described upper chi 2, as shown in Figure 2, the top of upper chi 2 is all provided with distance scale, and the center 20mm that leaves a blank does not establish scale, and its both sides all from inside to outside, from 0 to 90mm indicate scale respectively; Parallel with the both sides up and down of ruler, be provided with two row's aperture 2a in the centre of ruler, row's aperture on the left side starts with the position of the central point 12mm from ruler, and to establish an aperture to extend to ruler left end at a distance of every 2mm; One row's aperture on the right starts with the position of the central point 11mm from ruler, and to establish an aperture to extend to ruler right-hand member at a distance of every 2mm.Be provided with angle measuring calibration 2c in the center of ruler, identify angle for when drawing or measured angular.Circular hole 2b is provided with again, for being inserted in connector 3 at the center of upper chi.
Be provided with connector 3 between lower chi 1 and upper chi 2 to connect, see shown in Fig. 5 or Fig. 6.Lower chi 1 is fixed together with connector 3, and upper chi 2 can Horizontal rotating movable on connector 3.Described connector 3, axonometer 4 is established in centre; One end of axonometer 4 is provided with syringe needle 4a, makes center of circle fixing point for drawing bowlder; The other end of axonometer 4 is provided with tack 4b; Axonometer 4 can up and down and rotary moveable in connector 3.
When drawing using present embodiment or measure, method can with reference to as follows:
As shown in Figure 3, when taking measurement of an angle or draw an angle, ruler just can being placed on paper and (namely playing chi 1 to be attached on paper), by screwing on chi 2, checking angle measuring calibration, after forming the angle needed, by staying, chi 1 and upper chi 2 are painted; Shape shown in Fig. 3, directly can draw the angle of 75 degree.If measuring angle, rotatable lower chi 1 or upper chi 2, the angle making it be formed aligns with the angle that need measure, and can learn that angle is how many.While picture angle, also can calculate according to the scale on ruler, draw the length of side of needs; Can to paint easily like this square or triangle.
As shown in Figure 4, need picture camber line or bowlder, whole ruler is placed conversely, (namely going up chi 2 to be attached on paper), pin the tack 4b of axonometer 4 with hand, make syringe needle 4a withstand on paper, according to radius of a circle, separately get one-pen, nib is inserted corresponding aperture 2a on ruler, by pen around axonometer 4 turns.Present embodiment radius of can painting is circle between 11mm ~ 100mm.
During when not using or only for setting-out section, rotatable upper chi 2, together with coincideing with lower chi 1.
The utility model is not limited to embodiment above, and to one skilled in the art, under the prerequisite not departing from the utility model general principle, some changes made, all should be considered as belonging to protection domain of the present utility model.
