Description
Technical field
The utility model relates to a kind of mathematic(al) construction ruler.
Background technology
Ruler, also known as ruler, a ruler, is used to setting-out section (especially straight), measures instrument or the instrument of length.In the mapping of ruler rule, ruler is regarded as the instrument of the straight line can drawing infinite length.Ruler there is usually scale to measure length.Some ruler more leaves special shape as letter or circular hole in centre, facilitate user to draw.Ruler, usually with plastic cement or iron, also has with cardboard, wood, bamboo.
But current ruler usually will combinationally use in mathematic(al) construction, student generally needs to carry 4 rulers, and uses complicated, badly influences mapping speed.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of easy to carry, the mathematic(al) construction ruler marking triangle and angle that can be good.
For solving the problem, the utility model adopts following technical scheme:
A kind of mathematic(al) construction ruler, comprise acrylic semi-circular plate, first acrylic bar and the second acrylic bar, described acrylic semi-circular plate, first acrylic bar and the second acrylic bar are transparent setting, described acrylic semi-circular plate is provided with angle index, described first acrylic bar is provided with length scale, described length scale includes graduated in English and metric system scale, described acrylic semi-circular plate and the first acrylic bar are that integral type is arranged, described acrylic semi-circular plate is that hollow is arranged, described first acrylic bar is provided with groove, described second acrylic bar is embedded in acrylic semi-circular plate and arranges, described acrylic semi-circular plate and the second acrylic bar are rotationally connected.
As preferably, described second acrylic bar is carved with fine rule, person easy to use can aims at angle index on acrylic semi-circular plate.
As preferably, described second acrylic bar is provided with through hole, through hole, on fine rule, can help user to position the point on the ray of angle, can improve the precision of angle, accelerates mapping speed.
As preferably, described second acrylic bar is provided with delthyrium, described delthyrium, user can be helped to mark 30 ° of angles, 45° angle, 60 ° of angles and 90 ° of angles fast and reduce the mapping time.
The beneficial effects of the utility model are: by being provided with angle index on acrylic semi-circular plate, are combined with rotating second acrylic bar, can go out angle by fast; First acrylic bar is provided with length scale, person easy to use can measures and mark straight line, and by being provided with groove on the first acrylic bar, can the second acrylic bar be received in the first acrylic bar, good integrity, easy to carry.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of mathematic(al) construction ruler of the utility model.
Detailed description of the invention
As shown in Figure 1, a kind of mathematic(al) construction ruler, comprise acrylic semi-circular plate 1, first acrylic bar 2 and the second acrylic bar 3, described acrylic semi-circular plate 1, first acrylic bar 2 and the second acrylic 3 are transparent setting, described acrylic semi-circular plate 1 is provided with angle index (not shown), described first acrylic bar 2 is provided with length scale (not shown), described length scale includes graduated in English (not shown) and metric system scale (not shown), described acrylic semi-circular plate 1 and the first acrylic bar 2 are integral type setting, described acrylic semi-circular plate 1 is hollow setting, described first acrylic bar 2 is provided with groove (not shown), described second acrylic bar 3 is embedded in acrylic semi-circular plate 1 and arranges, described acrylic semi-circular plate 1 and the second acrylic bar 3 are rotationally connected.
Described second acrylic bar 3 is carved with fine rule 4, person easy to use can aims at angle index on acrylic semi-circular plate 1.
Described second acrylic bar 3 is provided with through hole 5, and through hole, on fine rule, can help user to position the point on the ray of angle, can improve the precision of angle, accelerates mapping speed.
Described second acrylic bar 3 is provided with delthyrium 6, user can be helped to mark 30 ° of angles, 45° angle, 60 ° of angles and 90 ° of angles fast, reduce the mapping time.
The beneficial effects of the utility model are: by being provided with angle index on acrylic semi-circular plate, are combined with rotating second acrylic bar, can go out angle by fast; First acrylic bar is provided with length scale, person easy to use can measures and mark straight line, and by being provided with groove on the first acrylic bar, can the second acrylic bar be received in the first acrylic bar, good integrity, easy to carry.
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, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.
