Four location holes are used for insertion of needle-like locating devices and play a role in locating, and one of the needle-like locating devices is selected to be used for locating when location is carried out; the first longitudinal seamed edge and the first transverse seamed edge are provided with centimeter scales, and the second longitudinal seamed edge and the second transverse seamed edge are provided with angle scales; according to the angle scales, the second location hole serves as the center of a circle, the first transverse seamed edge serves as a zero starting point, and the first longitudinal seamed edge serves as a 90-degree terminal point. The charting tool is simple in structure and has the functions of a ruler, a set square, compasses and a protractor.
Description
Technical field
The utility model relates to Combined drawing board used in a kind of how much drafting instruments, the particularly drawing of a kind of plane.
Background technology
At present in the application of how much drafting instruments, in particularly Graphing of Engineering, school instruction practice, often need multiple drawing and survey tool, such as set square, protractor, ruler and compasses etc., still, existing these teaching aids are all separate, thereby, often to carry and use several drafting instrument when drawing, not only use inconvenience, and reduce the operating efficiency of drawing and measuring.Existing Combined drawing board is complex structure often, and operation and position relationship are loaded down with trivial details, is unfavorable for the drawing needs of primary demand; And parts are various, be unfavorable for producing and assembling.
Summary of the invention
The technical problems to be solved in the utility model is: under the prerequisite that meets basic drawing needs, provide a kind of simple in structure, easy to use, Combined drawing board used in the drawing of plane.
In order to solve the problems of the technologies described above, drafting instrument of the present utility model, comprise a rectangular slab 1, and this rectangular slab comprises four seamed edges, the horizontal seamed edge 14 of the vertical seamed edge 13, the second of the horizontal seamed edge 12, the second of first vertical seamed edge 11, the first; This rectangular slab also comprises the first locating hole 01, the second locating hole 02, the 3rd locating hole 03 and the 4th locating hole 04, and above-mentioned locating hole inserts for the needle-like positioner, plays positioning action, during location, selects one of them to insert the needle-like positioner and positions; First vertical seamed edge 11 and the first horizontal seamed edge 12 are provided with centimeter scale 21, second vertical seamed edge and the second horizontal seamed edge are provided with angle index, this angle index be take the second locating hole as the center of circle, and the first horizontal seamed edge of take is the zero degree starting point, and the first vertical seamed edge of take is 90 degree terminals.
Above-mentioned drafting instrument also comprises the first arcuation stopper slot 26 be arranged on rectangular slab 1, and this stopper slot be take the second locating hole as the center of circle, and its upper and lower two arc edges are provided with the first angle index 23.
Above-mentioned drafting instrument also comprises the second arcuation stopper slot 25 be arranged on rectangular slab 1, and this stopper slot be take the second locating hole as the center of circle, and its upper and lower two arc edges are provided with the second angle index 24.
Above-mentioned drafting instrument also comprises the rectangular-shaped stopper slot 22 be arranged on rectangular slab 1.
Above-mentioned drafting instrument also comprises the linearity stopper slot 27 be arranged on rectangular slab 1.
Above-mentioned drafting instrument material is transparent engineering plastics.
The obtained beneficial effect of the utility model is: (1) is simple in structure, only has a rectangular slab to form; (2) production technology is simple, and production cost is low, only adopts two procedures plastic; (3) have ruler concurrently, set square, compasses, the function of four kinds of instruments of protractor, it is convenient to draw, high efficiency; (4) without any other annex, easy to carry.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1: 1, the rectangular slab of drafting instrument, the 01, first locating hole, the 02, first locating hole, 03, the first locating hole, the 04, first locating hole, 11, first vertical seamed edge, 12, second vertical seamed edge, the 13, the 3rd vertical seamed edge, the 14, the 4th vertical seamed edge, 21, centimeter scale, 22, rectangular-shaped stopper slot, the 23, first angle index, 24, the second angle index, 25, the second arcuation stopper slot, the 26, first arcuation stopper slot, 27, the linearity stopper slot.
