Abstract

The utility model relates to a multifunctional drafting scale, which is characterized by comprising a No. 10 imitational Song typeface exercise grid (1), an orthographic axonometric projection plotter (6), an oblique secondary auxiliary projection plotter (7), a parallel plotter (10) and a dimension marking grid (5) that is arranged above the scale and the right area; the parallel plotter (10) is arranged at the right lower part of the scale; the No. 10 imitational Song typeface exercise grid (1), a No. 7 imitational Song typeface exercise grid (2), a college card coating device (4), the orthographic axonometric projection plotter (6) and the oblique secondary auxiliary projection plotter (7) are clamped between the upper part of the dimension marking grid (5) and the parallel plotter (10); and a protractor (8) is arranged between the right part of the dimension marking grid (5) and the parallel plotter (10). The multifunctional drafting scale can improve the drafting exactness and precision, can draw the parallel which can not be completed by the existing drafting scale, has simple and practical structure, low cost and wide application, and meets the emergent requirement of the market.

Description

Multifunctional drawing ruler

Technical field

The utility model relates to a kind of manual plotting unit of application drawing specialty.

Background technology

The present special student of hand-drawing people, in mapping is often not to be to think deeply how sketch goes out profile, but too much being wasted in described, brought the drawing time long thus, the amount of fulfiling assignment is few, the accuracy that draws parallel lines is not high, describes the not attractive in appearance and length consuming time of some symbols, has influenced learning efficiency to a certain extent.

Summary of the invention

The purpose of this utility model provides a kind of compasses and the set of protractor function is one, and can draw the multifunctional drawing ruler of parallel lines at phenomenons such as the deficiency of existing manual drafting accuracy, the degree of accuracy and efficient are low.

The purpose of this utility model can realize by following measure:

A kind of multifunctional drawing ruler, it is characterized in that it includes the imitation Song-Dynasty-Style typeface training lattice No. 10, No. 7 imitation Song-Dynasty-Style typeface training lattices, university's card-coating device, the size marking lattice, isometric projection's plotter, cabinet projection's plotter, the parallel lines plotter, the size marking case is in the top of chi and the edge regions of keeping right, the parallel lines plotter is positioned at the lower right of chi, No. 10 imitation Song-Dynasty-Style typeface training lattices, No. 7 imitation Song-Dynasty-Style typeface training lattices, university's card-coating device, isometric projection's plotter, cabinet projection's plotter is clipped between size marking lattice top and the parallel lines plotter, and protractor is between size marking lattice right part and parallel lines plotter.

Advantage of the present utility model has:

The utility model can improve the degree of accuracy and the accuracy of drawing, and can draw drafting scale in the past the drafting of the parallel lines that can not finish.It is simple and practical, and cost is low, and application is wide, satisfies the active demand in market.

Description of drawings

Fig. 1 structural representation of the present utility model.

The specific embodiment

The utility model is further described below in conjunction with accompanying drawing:

As shown in Figure 1, it comprises 1, No. 7 imitation Song-Dynasty-Style typeface training lattices 2 of No. 10 imitation Song-Dynasty-Style typeface training lattices, college entrance examination card-coating device 3, university's card-coating device 4, size marking lattice 5, isometric projection's plotter 6, cabinet projection's plotter 7 the utility model, and they are directly drawn at the hollow out place with pencil in use and get final product.Also have protractor 8, lengthening chi 9, parallel lines plotter 10 in addition on the chi.Protractor 8 is the conventional amounts hornwork, directly measures with conventional method to get final product.Lengthening chi 9 should be that benchmark plays the lengthening effect from the right-hand horizontal level that rotates to main scale 13 when using.The base to should be overlapped by parallel line with institute when the parallel lines plotter is drawn, promotion slide bar 12 along chute 11 at suitable place drafting parallel lines.

Whole technologies and material used in the utility model adopt existing commercially available technology and product, can save production cost greatly.

When being in the drawing state with multifunctional drawing ruler, the user drawing rule should be shakeout.The material overwhelming majority of chi adopts polypropylene PP material, and (this material is a kind of high density, unprotected side chain, the linear polymer of high crystallization.Still a kind of translucent, hemicrystalline thermoplastic.Have high strength, and good insulating, density is little.Her fatigue durability is that other materials can't be compared with lubricity.So just removed the easy mill of traditional chi, fragile, problem such as wear no resistance.The raw material that suitable drawing rule is made) the little local of part adopts rigid high-strength material (chute of ruler partly adopts this material).Draw finishing the back user can be rolled into tubular with chi with the flexibility of polypropylene PP material, and with two suitable cap covers, the inside is used for adorning some other drawing instruments, for example: pencil, rubber or the like.Not only save taking up room of drawing rule and also effectively other drawing instruments organically have been placed on together, effectively prevented to forget when drawing the phenomenon of drawing instrument.

Other undeclared part that the utility model relates to is same as the prior art.
