Abstract
The utility model relates to a compasses ruler, which comprises a ruler and a pen point, wherein a vernier sliding vane is sleeved on the long side of the ruler, and the outer surface of the vernier sliding vane is perpendicularly clamped with the pen point for keeping the pen point vertical with the plane of the ruler, the top point of the long side of the ruler is arranged as an origin, and a needle type projection is arranged on the origin point. When in normal use, users can directly use the ruler to measure and draw straight lines, and use the needle type projection as the center of a circle when drawing a circle, then measure the radius, slide the sliding vane after determining the radius to make the distance between the pen point and the needle type projection to be equal to the length of the radius, finally fix the vernier sliding vane to press the needle type projection on the center of a circle, and then rotate the ruler and draw the pattern by the pen point. The compasses ruler has the advantages of elaborate appearance, reasonable technology, convenient use, flexible operation and the like.
Description
Technical field
The utility model relates to a kind of learning tool, especially a kind of compasses chi.
Background technology
In study and work, compasses and ruler are two kinds of indispensable measurement drawing instruments.But these two kinds of instruments are Different Individual at present, need carry respectively and use, and it is bigger to take up room, and inconvenience is carried and deposited, and makes troubles to people.In order to address the above problem, we provide a kind of new-type ruler that possesses the compasses function.
Summary of the invention
The purpose of this utility model provides a kind of compasses chi, is used to solve the problem of common ruler inconvenience accurate Drawing circular pattern.
For achieving the above object, the utility model compasses chi comprises ruler and nib, at the long limit socket vernier of ruler slide plate, connects nib in vernier slide plate outer surface cassette vertical fixing, keeps nib vertical with the ruler plane; Summit, the long limit of ruler is set to initial point, and is provided with the needle-like projection at the initial point place.
After adopting said structure, when normally using, the user can directly utilize ruler to measure, draw straight line; When drawing circular pattern, the user is the circular center of circle with the aciculiform projection, measure radius then, radius determines that the back slides to the corresponding graduation mark of ruler position to the vernier slide plate, makes the nib and the distance of aciculiform projection equal radius length, and is last, fixing vernier slide plate, the aciculiform projection is pressed in home position, and the rotation ruler utilizes nib to draw circular pattern.
Compared with the prior art, the beneficial effects of the utility model are: profile exquisiteness, reasonable, easy to use, the flexible operation of technology, collection ruler and two kinds of effects of compasses, the condition for study that facilitates.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the utility model compasses chi.
Number in the figure: 1 is that ruler, 2 is that nib, 3 is that vernier slide plate, 4 is that initial point, 5 is the needle-like projection.
The specific embodiment
As shown in Figure 1, the utility model compasses chi comprises ruler 1 and nib 2, at ruler 1 long limit socket vernier slide plate 3, connects nib 2 in vernier slide plate 3 outer surface cassette vertical fixing, keeps nib 2 vertical with ruler 1 plane; Summit, ruler 1 long limit is set to initial point 4, and is provided with needle-like projection 5 at initial point 4 places.
Claims (1)
