Abstract
The utility model belongs to the technical field of drawing tools and perpendicularly relates to a multifunctional protractor. When existing drawing tools are used to draw semicircles, circles and angles and measure angles, compasses, rulers, set squares, protractors are needed, and the drawing tools are inconvenient to use, carry and store. The multifunctional protractor comprises a protractor (1) and a ruler (2) and is characterized in that one end of the ruler (2) capable of rotating around the center of a circle (3) is fixed to a center of a circle (3) of the protractor (1) through a connector (6), and the other end of the ruler (2) is aligned with the inner edge of the protractor (1) and is provided with a chalk holder (4). The multifunctional protractor is simply modified from an existing protractor and accordingly is capable of serving as a protractor and for measuring angles, drawing angles and drawing lines.
Description
Technical field
The utility model belongs to the drawing instrument technical field, is specifically related to a kind of multi-functional graphometer.
Background technology
In the present drawing instrument, when drawing semicircle, circle, angle and measuring angle, need compasses, ruler, set square and protractor etc., use, carry, deposit all inconvenient.
Summary of the invention
The purpose of the utility model provides a kind of multi-functional graphometer, can use a drawing instrument to realize a plurality of functions.
The technical scheme that the utility model adopted is
A kind of multi-functional graphometer comprises graphometer and ruler, it is characterized in that, an end of the said ruler that can rotate around the center of circle is fixed on the circle centre position of graphometer through connector; The other end of said ruler aligns with the inside edge of graphometer, and is provided with the chalk folder at this end.
The straight flange of above-mentioned graphometer is provided with graduation mark.
Be provided with groove on the above-mentioned ruler along the longitudinal direction, slidably chalk folder is set in the groove.
The graphometer of the utility model carries out simple modifications on the structure of existing graphometer, make it can make compasses and use, again energy measurement angle, picture angle and picture straight line.
Description of drawings
Fig. 1 is the structural scheme of mechanism of the utility model graphometer.
Among the figure, 1. graphometer, 2. ruler, the 3. center of circle, 4. chalk folder, 5. graduation mark, 6. connector.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The structure of the multi-functional graphometer of the utility model is as shown in Figure 1; On the architecture basics of existing graphometer 1, do simple modifications; 3 places, the center of circle at graphometer 1 are provided with a connector 6, and an end that makes this ruler 2 is fixed on 3 places, the center of circle of graphometer 1 through connector 6, and can be around the center of circle 3 rotate; The other end of this ruler 2 is alignd with the inside edge of graphometer 1, and be provided with chalk folder 4 at an end place of this ruler 2.The middle longitudinally groove that is provided with in ruler 2 upper edges, this chalk folder 4 can move along this groove.On the straight flange of graphometer 1, be carved with graduation mark 5.
During use, except the basic function that can use graphometer,, can be used for the picture straight line owing on the straight line of graphometer graduation mark 5 is arranged; Also can draw straight line along ruler 2; And, be a limit of angle with the straight flange of graphometer, be another limit of angle with ruler 2, according to the number of degrees on the graphometer, can draw corresponding angle; Can also move chalk folder 4 to the position that needs according to the size on the ruler 2, on the chalk folder, load onto chalk, can draw the semicircle and the circle of different radii.Realized the purpose of the multiple function of a kind of instrument.
