Abstract
The utility model belongs to the improvement of a drawing apparatus; a triquetrum proportional ruler, a graphometer and a pair of triangle rulers are common drawing instruments; the multifunctional triangle ruler simultaneously has various functions of various proportion scale marks on the proportional ruler, angle reticle on the graphometer and angular separation with the 90 DEG, 45 DEG, 30 DEG and 60 DEG on the pair of triangle rulers; one ruler has the functions of the triquetrum proportional ruler, the graphometer and the pair of triangle rulers and has other new function. The drawing is quick, convenient and accurate making use of the multifunctional triangle ruler. The utility model has the advantages of easy fabrication, low cost.
Description
The utility model belongs to the improvement to drawing appliance.
Triangular proportional scale, graphometer and a pair of set square are the drawing instruments of using always, and their function has nothing in common with each other, and be often indispensable during drawing.
The purpose of this utility model is design one a novel set square, can possess all functions of triangular proportional scale, graphometer and a pair of set square, thereby replace them in drawing.
The utility model mainly is that profile is designed to isosceles right triangle, is carved with various scale graduation lines commonly used on its each limit respectively, and inside is provided with the graphometer of recessed sky and forms the little set square that protrudes by 30 ° of hypotenuses, 60 ° of hypotenuses.The multiple function that therefore can possess triangular proportional scale, graphometer and a pair of set square commonly used.
Survey sub-elliptical for the ease of drawing just waiting, on 30 ° of hypotenuses of little set square, designed
: 1 graduation mark.
Accompanying drawing is the multifunctional triangle organigram.
Multifunctional triangle is that a profile drift angle (1) is that 90 ° and (2) are 45 ° set square, various scale graduation lines commonly used are carved with in each limit (3), (4), (5), and inside is provided with the graphometer (6) of recessed sky and is made of the little set square of protrusion 30 ° of hypotenuses (7), 60 ° of hypotenuses (8).On 30 ° of hypotenuses, be provided with the scale direction perpendicular to the long limit of set square (3)
: 1 ratio groove (9).
The utility model possesses the function of triangular proportional scale, graphometer and a pair of set square, and can be used for drawing and is just waiting the survey sub-elliptical. Mapping accurately, and is easy to use, improves mapping speed, and easy to manufacture, with low cost.
Claims (2)
1, a kind of drift angle is 90 ° an isoceles triangle plate, it is characterized in that: be carved with various scale graduation lines commonly used on three straight flanges (3) of set square, (4), (5); Set square inside is provided with the graphometer (6) of recessed sky, and is provided with 30 ° hypotenuse (7) in the graphometer centre and 60 ° hypotenuse (8) is formed the little set square that protrudes.
2,, it is characterized in that being carved with on 30 ° of hypotenuses (7) the scale direction perpendicular to the long limit of set square (3) according to the said multifunctional triangle of claim 1
: 1 ratio groove.
