Abstract
A ruler belongs to stationery and mainly resolves the problems that when a ruler is used, drawing is influenced due to small scale marks which can not be recognized clearly. The ruler comprises a ruler body, and is characterized in that one side of the ruler is a projecting structure, the other side of the ruler is a flat-plate structure; the projecting structure is a semi-cylinder transparent solid body; the bottom surface of the ruler is a plane provided with marks; and the marks are positioned on one side of the projecting structure. When using the ruler, a user can observe the marks from the upper portion of the projecting structure, and the marks are amplified, thereby drawing can be more accurate and convenient for people.
Description
Technical field
The utility model relates to a kind of stationery, a kind of specifically ruler.
Background technology
Because graduation mark is less, recognize unclear when using ruler, influence is drawn.
The utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of can amplify the ruler that shows with scale.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ruler, comprise the ruler body, and it is characterized in that: described ruler body one side is a projective structure, and opposite side is a slab construction; Described projective structure is the transparent solid of semicircle column type, and its bottom surface is the plane, has scale, scale to be positioned at projective structure one side on the plane.
The beneficial effects of the utility model are: its projective structure can utilize optical principle to amplify the demonstration of scale.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 projective structure, 2 slab constructions, 3 scales.
The specific embodiment
As shown in Figure 1, a kind of ruler comprises the ruler body, and described ruler body one side is a projective structure 1, and opposite side is a slab construction 2; Described projective structure 1 is the transparent solid of semicircle column type, and its bottom surface is the plane, and scale 3 is arranged on the plane, and scale 3 is positioned at projective structure 1 one sides.
During use, when observing scale 3 from projective structure 1 top, scale 3 is exaggerated, and is that people are more convenient when mapping.
Claims (1)
1. a ruler comprises the ruler body, it is characterized in that: described ruler body one side is a projective structure, and opposite side is a slab construction; Described projective structure is the transparent solid of semicircle column type, and its bottom surface is the plane, has scale, scale to be positioned at projective structure one side on the plane.
