Abstract
The utility model relates to a kind of ruler, comprise ruler body, the bottom surface of described ruler body is provided with graduation mark along portion, the bottom surface upper level of described ruler body is provided with the first stripe shape fin, the bottom surface lower horizontal of described ruler body is provided with the second stripe shape fin, and described ruler body is transparent material.Ruler bottom surface is erected by stripe shape fin by the utility model, make ruler bottom surface and working face contactless, prevent graduation mark to be worn, extend the service life of ruler; Need not wait for that ink is air-dry, can ruler be moved, can not the straight line garland of just having finished.
Description
Technical field
The utility model relates to a kind of stationery, particularly a kind of ruler.
Background technology
Ruler is widely used in the subjects such as mathematics, measurement, engineering.Ruler is also referred to as a chi, and be a kind of very conventional measuring length apparatus, more general as stationery, almost every pupil all staff one, are generally used for measuring shorter distance or drawing straight line.Generally, print graduation mark on the upper edge of ruler bottom surface, because ruler bottom surface directly contacts with working face, if things go on like this, cause the wearing and tearing of graduation mark, cannot normally use, need the ruler more renewed, cause great waste.Therefore, need to propose a kind of new ruler.
Summary of the invention
The purpose of this utility model is to provide a kind of ruler, to solve the defect existed in prior art.
The purpose of this utility model is realized by following technical proposals: a kind of ruler, comprise ruler body, the bottom surface of described ruler body is provided with graduation mark along portion, the bottom surface upper level of described ruler body is provided with the first stripe shape fin, the bottom surface lower horizontal of described ruler body is provided with the second stripe shape fin, and described ruler body is transparent material.
The utility model compared with prior art tool has the following advantages:
1, ruler bottom surface is erected by stripe shape fin by the utility model, make ruler bottom surface and working face contactless, prevent graduation mark to be worn, extend the service life of ruler.
2, ruler bottom surface is erected by stripe shape fin by the utility model, makes the upper edge of ruler contactless with working face, after the setting-out of use free ink pen, need not wait for that ink is air-dry, can move ruler, can not the straight line garland of just having finished.
3, by pressing ruler on along portion or lower to portion, by stripe shape fin as fulcrum, make relative another side produce small lifting, finger of being more convenient for embeds to be got from working face by ruler bottom ruler, unnecessaryly again ruler is moved to edge along working face and gets final product complete operation.
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the schematic diagram along portion on pressing ruler.
Description of reference numerals:
1-ruler body; 2-graduation mark; 3-first stripe shape fin; 4-second stripe shape fin; 5-annular boss; 6-manhole; H1-distance 1; H2-distance 2.
Detailed description of the invention
See Fig. 1, Fig. 2, a kind of ruler, comprise ruler body 1, the bottom surface of described ruler body is provided with graduation mark 2 along portion, the bottom surface upper level of described ruler body is provided with the first stripe shape fin 3, the bottom surface lower horizontal of described ruler body is provided with the second stripe shape fin 4, and described ruler body is transparent material.
In the present embodiment, the length of described ruler body 1 is 208 millimeters, and width is 34 millimeters.Ruler body adopts transparent material injection mo(u)lding, as Merlon, polyvinyl chloride, polystyrene etc.In the present embodiment, the height of described first stripe shape fin 3 is 0.5 millimeter, and the height of described second stripe shape fin 4 is 0.5 millimeter.
See Fig. 1, Fig. 2, in the present embodiment, by the first stripe shape fin 3, second stripe shape convex shuttle 4, ruler bottom surface is erected, make ruler bottom surface and working face contactless, prevent graduation mark to be worn, extend the service life of ruler.After the setting-out of use free ink pen, need not wait for that ink is air-dry, moves ruler immediately, also can not the straight line garland of just having finished.Make because ruler mostly is transparent material, erected ruler bottom surface by the first stripe shape fin 3, second stripe shape convex shuttle 4, the cut that can reduce straightedge surface produces, and makes ruler lasting as new.
In the present embodiment, ruler body is that transparent material is made, making the first stripe shape fin on ruler bottom surface, the second stripe shape fin can be in sight through ruler body, when drawing parallel lines, the first stripe shape fin or the second stripe shape fin can be used as with reference to line.
In prior art, graduation mark is normally initial by zero graduation, to 15 or 20 centimetres of terminations.Because one end of zero graduation distance ruler is comparatively near, should not hold when drawing straight line, the easy sideslip of ruler.Further, the zero graduation in described graduation mark is arranged on 1/4th positions of described graduation mark.By zero graduation being placed in 1/4th positions of ruler, the holding of more convenient ruler is stablized, and also closer to the custom of the random setting-out of people, can realize to both direction setting-out.
Further, increase progressively successively on the left of described zero graduation and five scale values are set, increase progressively successively on the right side of described zero graduation and 15 scale values are set; As shown in Figure 1.
See Fig. 2, Fig. 3, further, the distance h1 between described first stripe shape fin and the upper edge of described ruler body is 8 millimeters, and the distance h2 between described second stripe shape fin and the lower edge of described ruler body is 8 millimeters.By pressing ruler on along portion or lower to portion, by stripe shape fin as fulcrum, make relative another side produce small lifting, finger of being more convenient for embeds to be got from working face by ruler bottom ruler, unnecessaryly again ruler is moved to edge along working face and gets final product complete operation.
See Fig. 1, further, the left part of described ruler body arranges annular boss 5, is provided with manhole 6 at the center of annular boss, and the diameter of manhole is 5 millimeters.One end of described annular boss is higher than 0.5 millimeter, the surface of described ruler body, and the other end of described annular boss is higher than 0.5 millimeter, the bottom surface of described ruler body.With in the manhole of penholder on ruler, be convenient for people to play in hand, enhance the favorable rating of people to ruler.
The content of the present embodiment is only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
