Description
Technical field
The utility model relates to a kind of drawing tools, particularly a kind of special ruler for accountants.
Background technology
In accountancy, tabulation of drawing is the technical ability that must grasp, but existing drawing ruler function singleness, the demand of existing accountancy can not be met far away.
Utility model content
The purpose of this utility model is to provide a kind of special ruler for accountants, solves by the utility model the polygon problem that teacher not easily draws standard.
The purpose of this utility model is achieved through the following channels:
A kind of special ruler for accountants, comprise chi body, described chi body is provided with scale, it is characterized in that, described chi body quantity is at least three, described chi body two ends all arrange through hole, connected by the fastener inserted in through hole between described chi body, described fastener comprises catch, and described baffle plate comprises left catch and right catch, and described left catch one side is fixed ear with a left side and is connected, described left catch another side is connected with a nut, described right baffle plate one side is fixed ear with the right side and is connected, and described right catch another side is connected with a bolt, and described nuts and bolt cooperatively interacts; Described through hole both sides are respectively arranged with pad, described pad are provided with angle graticule; Described chi body is provided with straight graticule, and described straight graticule two ends are all connected with pad center; Be connected with the first magnet between described left catch and nut, be connected with the second magnet between described right catch and bolt, described first magnet is contrary with the second magnet opposite face magnetic; Described first magnet right-hand member is provided with a draw-in groove, and described second magnet left end is provided with a card column, and described draw-in groove and card column cooperatively interact; The end of chi body is connected with magnifying glass by hinge ring.
The utility model beneficial effect:
The utility model not only can work as ruler use can also draw polygonal limit row, teacher only need will think that the polygonal limit number of picture selects corresponding chi body number, then by fastener, junction is linked together, then corresponding angle is selected can to draw equilateral polygon by fastener is fastening again by straight graticule, the utility model structure is simple, can load and unload, easy to loading and unloading.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pad syndeton schematic diagram;
Fig. 3 is the utility model fastener syndeton schematic diagram;
In figure, 1, chi body, 2, scale, 3, straight graticule, 4, angle graticule, 5, pad, 6, left fixing ear, 7, left catch, the 8, first magnet, 9, nut, 10, draw-in groove, 11, bolt, 12, card column, the 13, second magnet, 14, right catch, 15, right fixing ear, 16, magnifying glass.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment:
As shown in Figure 1 to Figure 3, a kind of special ruler for accountants, comprise chi body 1, described chi body is provided with scale 2, described chi body quantity is at least three, described chi body two ends all arrange through hole, connected by the fastener inserted in through hole between described chi body, described fastener comprises catch, described baffle plate comprises left catch 7 and right catch 14, described left catch one side is fixed ear 6 with a left side and is connected, described left catch another side is connected with a nut 9, described right baffle plate one side is fixed ear 15 with the right side and is connected, described right catch another side is connected with a bolt 11, described nuts and bolt cooperatively interacts, described through hole both sides are respectively arranged with pad 5, described pad are provided with angle graticule 4.
Described chi body is provided with straight graticule 3, and described straight graticule two ends are all connected with pad center.Whether angle corresponding during the convenient rotation of straight graticule is more accurate, but also vertical when can weigh expansion ruler.
Be connected with the first magnet 8 between described left catch and nut, be connected with the second magnet 13 between described right catch and bolt, described first magnet is contrary with the second magnet opposite face magnetic.More easily will fastener be loaded onto by the attraction between the first magnet and the second magnet, convenient and practical.
Described first magnet right-hand member is provided with a draw-in groove 10, and described second magnet left end is provided with a card column 12, and described draw-in groove and card column cooperatively interact.By the situation that draw-in groove and card column prevent bolt rotation tension from not easily unloading.
The end of described chi body 1 is connected with magnifying glass 16 by hinge ring, can pass through magnifying glass 16 amplification data form font.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those of ordinary skill in the art are in the technical scope disclosed by the utility model; the change can expected without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
