Abstract
The utility model discloses the fast drawing rule of a kind of three-view diagram, it solve existing drawing rule and have that Hand drawing efficiency is low, drawing step is loaded down with trivial details and the problem such as drawing quality is not high, it is characterized in that: it is 45 ° of T-shaped chutes that the right angle back side of square (1) offers with right-angle side chi, location draw runner (2) is T-type structure vertical bar, with 45 ° of T-shaped chute interference fits; The two ends of location draw runner (2) are provided with locating pin (3); Ruler (4) back side is provided with square chute, above the right-angle side chi that can be positioned over square (1), with the right-angle side chi matched in clearance of square (1).The Fast Drawing of " high concordant, wide equal and longly to align " projection law can be realized in three-view diagram.Have scientific structure, easy to carry, simple to operate, the fast advantage such as high-quality, market prospects are very wide.
Description
One, technical field
The utility model belongs to engineering drawing field of tool, relate in particular to a kind of can " lead, bow, left " fast drawing rule of three-view diagram common in drawn engineering drawing quick, fastly.
two, technical background
In Graphing of Engineering, descriptive geometry content is the basis of Graphing of Engineering, and in the process of study Graphing of Engineering, Hand drawing is to the basic projection law understanding Graphing of Engineering, expression and the method for drafting of grasping Graphing of Engineering have very large help, and the drawing instrument that current Hand drawing is conventional has T-square, ruler, set square, protractor, compasses, divider and drawing board etc., in the three-view diagram drawing process of Graphing of Engineering, its projection law is " high concordant, wide equal and longly to align " realization, carry out combination drafting often through above-mentioned common various drawing instruments and obtain, due to each drawing instrument function singleness, method for drafting so just can be caused inflexible, drawing efficiency is low, graphing precision is on the low side, the not high phenomenon of drawing quality, therefore improves Hand drawing efficiency, drawing quality, needs a kind of composite behaviour badly good, prompt drawing instrument just, makes Hand drawing become more flexible, interesting, the learning interest of student can be improved like this, the Hand drawing time can be saved again.
Three, utility model content
The purpose of this utility model be exactly in Graphing of Engineering for people provide a kind of rational in infrastructure, easy to carry, use simple, without the need to square by means of T-square, drawing board edge, protractor, divider etc. and in drawing process without the need to taking away the drawing rule of can be quick, fast common in the drawn engineering drawing in ground " lead, bow, a left side " three-view diagram.
The technical solution of the utility model is: it comprises square, the location drawing instrument such as draw runner and ruler, offer at the right angle back side of square with right-angle side chi is 45 ° of T-shaped chutes, location draw runner is T-type structure vertical bar, with 45 ° of T-shaped chute interference fits, and be provided with locating pin at the two ends of location draw runner.The ruler back side is provided with square chute, above the right angle edge strip that can be positioned over square, coordinates with the right-angle side interspace of square.
The beneficial effects of the utility model are, owing to adopting square, location draw runner and ruler three combination, not only synchronously can draw main, top view, also synchronously can draw out left view rapidly, both Hand drawing efficiency be can improve, accuracy rate and the drawing quality of Hand drawing also can be improved.Have scientific structure, easy to carry, use simply, the quick advantage such as high-quality, market prospects potentiality are very large.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Four, accompanying drawing explanation
Fig. 1 be the utility model draw bow, left view time assembled state structural representation;
Assembled state structural representation when Fig. 2 is the utility model drafting master, top view;
Assembled state structural representation when Fig. 3 is the utility model drafting master, left view;
Fig. 4 is the utility model set square and locates local assembling section when draw runner combines;
Fig. 5 is the utility model set square and ruler local assembling section when combining.
In figure: 1 is square, 2 is location draw runner, and 3 is locating pin, and 4 is ruler.
Five, detailed description of the invention
Of the present utility model three are made up of square 1, location draw runner 2 and ruler 4 etc. depending on drawing rule, adopt conventional PS plastic material, according to the different square 1 making dimension size respectively of the specification used, ruler 4 and location draw runner 2, locating pin 3 adopts standard component.Offering at the right angle back side of square 1 with right-angle side chi is 45 ° of T-shaped chutes, and location draw runner 2 is T-type structure vertical bar, with 45 ° of T-shaped chute interference fits; The two ends of location draw runner 2 are provided with locating pin 3; Ruler 4 back side is provided with square chute, above the right-angle side chi that can be positioned over square 1, with the right-angle side chi matched in clearance of square 1.
As shown in Figure 1, location draw runner 2 is interspersed in 45 ° of T-shaped chutes of square 1 right angle setting, by locating pin 3, location draw runner 2 and square 1 are fixed on conventional drawing board, namely square 1 is ensured when draw runner 2 slippage of location, edge steadily without swinging or inconsistent phenomenon, by the slippage of square 1 along location draw runner 2, the Fast Drawing of " wide equal " projection law in three-view diagram can be realized.As shown in Figure 2, the square chute arranged at ruler 4 back side embeds on the level right angle limit chi of square 1, the square chute offered when ruler 4 back side in left-right direction slippage time, the Fast Drawing of " long align " projection law can be realized in three-view diagram.As shown in Figure 3, the square chute offered when ruler 4 back side to be placed on square 1 vertical edges chi and along its above-below direction slippage time, the Fast Drawing of " high concordant " projection law in three-view diagram can be realized.
The utility model is skillfully constructed, structure simple, easy to operate, fast, efficient, and design is unique, safe and reliable, not only synchronously can draw main, top view, also synchronously can draw out left view rapidly, improves Hand drawing efficiency, accuracy rate and drawing quality.
