Abstract
The utility model relates to a drawing tool and specifically a ruler with a compass. The ruler with the compass is provided with a ruler with scales, wherein a locating needle is arranged at the zero scale of the ruler; a circle-drawing through hole is arranged below the rule scales; and the ruler at the locating needle is provided with a groove; the locating needle is arranged in the groove and is connected with a groove wall through a pin shaft; when a circle is unnecessary to drawn, the locating needle is folded to be hidden in a groove at the backside; the ruler with the compass when being used as a ruler can prevent scratching; when the ruler with the compass is used for drawing a circle, the locating needle is unfolded to determine the center of the circle and then a pen tip is inserted into the circle-drawing through hole at a corresponding scale to drive the ruler to rotate around the locating needle to obtain a circle with a corresponding radius. Therefore, the ruler with the compass, disclosed by the utility model, has the advantages of a simple structure, low cost, operation convenience and the like.
Description
Technical field
The utility model relates to a kind of drafting instrument, specifically a kind of ruler of band compasses easy to use.
Background technology
As everyone knows, compasses and ruler are two kinds of higher drafting instruments of current frequency of utilization, are applied to school and the unit that needs drawing more; Draw bowlder, two legs with compasses measure radius on ruler earlier, operate on paper with compasses then, and for first user, program is loaded down with trivial details, and the picture precision is not high.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, provide a kind of with compasses and ruler be integrated, it is easy to use, the ruler of band compasses easy and simple to handle.
The utility model can reach through following measure:
A kind of ruler with compasses is provided with the ruler of being with scale, it is characterized in that ruler zero graduation place establishes pilot pin, and ruler scale below is provided with the picture round tube hole.
The ruler at the described pilot pin of the utility model place is provided with groove, and pilot pin is located in the groove and through bearing pin and is connected with groove walls, does not need the picture bowlder, and pilot pin is folding, is hidden in the groove of the chi back side, makees ruler and uses, and can prevent to scrape and draw; Draw bowlder, pilot pin is launched to confirm the center of circle.
The utility model is drawn bowlder owing to adopt said structure, and needle point is fixed on the center of circle; Nib is inserted in the picture round tube hole of corresponding scale, drive ruler with nib and rotate, can obtain the circle of relevant radii around pilot pin; Have advantages such as simple in structure, with low cost, easy to operate.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be further described:
As shown in the figure, a kind of ruler with compasses is provided with the ruler 1 of being with scale; 0 scale place of ruler 1 establishes pilot pin 2, and ruler 1 is provided with groove, and pilot pin 2 is located in the groove and through bearing pin and is connected with groove walls; Do not need the picture bowlder, pilot pin 2 is folding, be hidden in ruler 1 back side groove; To use, can prevent to scrape and draw as ruler; When needs picture bowlder, pilot pin 2 is launched to confirm circle, ruler 1 scale below is provided with the picture round tube hole, and ruler 1 can adopt plastics-production; Also can adopt manufacture of materials such as timber, metal, draw bowlder, needle point is fixed on the center of circle; Nib is inserted in the picture round tube hole of corresponding scale, drive ruler with nib and rotate, can obtain the circle of relevant radii around pilot pin; Have advantages such as simple in structure, with low cost, easy to operate.
