detailed description

The utility model will be described in detail below in conjunction with accompanying drawing:

As shown in Figure 1-2:

A radar chart drawing tool, comprising a disk 1, the disk 1 is provided with an angle, the center of the disk 1 is provided with a rotating shaft, the rotating shaft is provided with a ruler, and the ruler is rotatably connected to the rotating shaft. Described straightedge comprises connecting part 2 and rotating part 3, and described connecting part 2 is hinged at the rotating shaft place and the width of described rotating part 3 is less than the width of connecting part 2, and described connecting part 2 and rotating part 3 circle around the The center of the circle rotates; a strip through hole 4 is provided along the length direction of the rotating part 3, and a slide block 5 matched with it is provided in the strip through hole 4, and the slide block 5 can Slide freely in the through hole 4 of the bar, and a rotating plate 6 is also hinged on the slider 5, and the rotating plate 6 is used to draw a straight line flush with the center of the disc 1 and a straight line with an arbitrary slope. The slider 5 is free to rotate at the center; the rotating plate 6 is provided with a scale and a protractor 7 is provided in the middle of the rotating plate 6; Several circular through holes 8 are uniformly arranged in the length direction of the shaft.

In this way, when drawing a radar chart, through the rotation of the rotating plate 6 and the rotation of the straightedge, a straight line with any slope can be drawn, and a plurality of circles with a hierarchical relationship can be drawn through the circular through hole 8 on the rotating part 3 The ring is convenient for comparing and classifying the data; the rotating plate 6 is also provided with a protractor 7 for measuring the slope of each straight line in the radar diagram, which is convenient for analyzing the data; since the width of the rotating part 3 is smaller than the width of the connecting part 2 , so it is very convenient to use the rotating plate 6 to draw a straight line flush with the center of the disc 1, which reduces the drawing error and improves the accuracy of the data.

The connecting part 2 is rectangular and is rotatably connected to the rotating shaft at one corner thereof, and the connecting part 2 covers a quarter of the area of the disc 1 . In this way, it can effectively ensure that the width of the rotating part 3 is smaller than the radius of the disc 1 when drawing the radar chart, and a gap is formed between the width direction of the rotating part 3 and the center of the disc 1 to facilitate the drawing of the rotating plate 6 and the center of the disc 1. The area of straight lines with the centers of the circles.

The rotating plate 6 is an isosceles right-angled triangular plate. In this way, it is convenient to draw right angles or verify the vertical relationship between each in the radar chart.

Scales are provided on three sides of the rotating plate 6 . This facilitates the control and measurement of the length of the straight line.

When the hypotenuse of the rotating plate 6 is parallel to the rotating part 3 , the hypotenuse of the rotating plate 6 is flush with the center of the disc 1 . In this way, the accuracy of the drawn radar chart can be guaranteed, and the problem that the radiation drawn by the traditional drawing tool deviates from the center of the disk 1 by a certain distance and the drawing error is large is avoided.

The protractor 7 is a semicircular hollow in the middle of the rotating plate 6, and a scale is provided at the arc edge of the semicircular hollow.

The diameter of the circular through hole 8 is larger than that of the scribing tool, and is used for drawing arcs. Like this, when drawing the circular ring with hierarchical relationship, the end of drawing utensils such as pen, chalk etc. can be inserted in circular through hole 8 and draw circular arc or circular ring, and near circular through hole 8 can Set the radius mark, which is convenient for controlling or measuring the radius of the drawn arc.

The rotating part 3 is integrally made with the connecting part 2 .

The beneficial effects of the utility model: by setting a rotating rotating plate on a rotating ruler, the tool set draws straight lines, oblique lines and measuring slopes in one, which greatly facilitates the drawing of radar charts in the teaching process, Moreover, the structural design is reasonable, the drawn radiation line is flush with the center of the disc, and the drawing is accurate, which is convenient for accurate analysis and processing of radar chart data, reduces drawing errors, is convenient to use, and is easy to popularize.

The above embodiments are only used to illustrate the technical solution of the utility model without limitation.
