The specific embodiment
Embodiment 1
Consult shown in Figure 1, a kind of line segment Equant ruler, comprise chi band 1, evenly divided line 2, its chi band 1 adopts elastomeric material to make, as silicon rubber, General Purpose Rubber, transparent materials such as rubber plastic film, chi band 1 is rectangular chi shape, length is divided different specification size, chi band 1 double-edged two long limit is provided with the evenly divided line 2 of different specification size, but the line segment of four kinds of different five equilibriums of five equilibrium during use, is held chi band 1 two ends, with 1 elongation of chi band, make it and want the line segment of five equilibrium isometric, and justify align, the evenly divided line 2 on it also extends thereupon, can draw the line segment n five equilibrium of wanting five equilibrium from the n evenly divided line 2 of chi band 1 mark, make the five equilibrium mark immediately.Present embodiment is single chi type, and structure and simple, with low cost can two people be used, and also can fix with drawing pin by an end, and a people independently uses.
For making things convenient for the individual independently to use and carrying, the utility model can also adopt following example structure.
Consult shown in Figure 2, present embodiment is a runner type structure, mainly constitute by chi band 1, evenly divided line 2, box body 3, rope 4, elastomer 5, runner 6, baffle plate 7, lid 8 etc., its chi band 1 structure is with embodiment 1, two bar rule bands, 1 tow sides are provided with the evenly divided line 2 of different specification size, and be arranged in the transparent box body 3, chi band 1 one ends and box body 3 connect firmly, the other end connects rope 4, rope 4 is on the runner 6 of box body 3 one ends, rope 4 also can be a tooth bar, and runner 6 also can be a gear; Be provided with in the box body 3 and be used for the spacing baffle plate 7 of chi band 1, be fixedly connected with elastomer 5 on the baffle plate 7 and contact with runner 6, elastomer 5 can be selected spring, rubber and plastic piece etc. for use, also can be provided with push-and-pull lid 8 on the box body 3.During use, forward or reverse runner 6, a wherein bar rule band 1 elongation, the longest can be to baffle plate 7, by runner 6 and elastomer 5 frictions or wheel and rack engagement, make 1 elongation of chi band and remain on a certain position, can wait fast according to the evenly divided line 2 on it and tell the line segment n five equilibrium of wanting five equilibrium.
Embodiment 3
Consult shown in Figure 3, present embodiment is the push-pull type structure, mainly constitute by chi band 1, evenly divided line 2, rope 4, guide rail 9, slide block 10 etc., its chi band 1 structure is with embodiment 1, chi band 1 two ends are connected on guide rail 9 and the slide block 10 by rope 4, chi band 1 can rope 4 be that axle rotates, and guide rail 9 and slide block 10 are as the structure of existing slide measure.During use, moving slider 10 makes 1 elongation of chi band, and is locked in a certain position by slide block 10 screws, can wait fast according to the evenly divided line on the chi band 12 and tell the line segment n five equilibrium of wanting five equilibrium.Time spent not, can pack into matched chi box or chi bag.
