Abstract

The utility model relates to the technical field of cultural goods, in particular to a novel ruler, which comprises a ruler body; a plurality of convex points are arranged on the lower surface of the ruler, and concave points or a concave surface is arranged on the upper surface of the ruler. After the utility model adopts the structure, the convex points which are in a shape of an arc surface are arranged on the lower surface of the ruler, through the contact between the convex points and paper, the friction is reduced when being pushed, and simultaneously, the paper surface is prevented from being polluted by handwriting of the ruler edges. On the other hand, the convex points or the convex surface is arranged on the upper surface of the ruler, the novel ruler is favorable for finger positioning, finger slip when being pushed is avoided, and users can easily control the ruler.

Description

Novel ruler

Technical field:

The utility model relates to the cultural goods technical field, special a kind of novel ruler.

Background technology:

Existing ruler comprises ruler, set square, protractor etc., is the form of positive and negative two sides scale, reverse side during use (lower surface) contact paper, and positive (upper surface) then pinned with hand.Owing in use often need to slide, when existing ruler slides owing to be whole lower surface contact paper, add left-hand seat and applied certain pressure, being easy to drive paper slides simultaneously, make troubles to the user, and because the contact at edge, also can make pencil powder on the ruler or the person's handwriting paper of making dirty; On the other hand, pin in the upper surface moving process with hand, be easy to skid, check and correction again again is therefore very inconvenient then.

The utility model content:

The purpose of this utility model is the above-mentioned weak point of hateful existing product, and the novel ruler of a kind of simple in structure, result of use significantly better than existing ruler is provided.

The utility model realizes that the technical scheme of the employing of its purpose is: this novel ruler comprises the ruler body, and the lower surface of described ruler is provided with several salient points.

Described salient point becomes arc surfaced.

The upper surface of described ruler is provided with concave surface or concave point.

The utility model is provided with the arc surfaced salient point at the ruler lower surface after adopting said structure, contacts by salient point and paper etc., has both reduced the friction when promoting, and the while can prevent the papers of making dirty such as person's handwriting at ruler edge again; On the other hand, the ruler upper surface is provided with concave surface or concave point, helps the finger location, and finger slides when preventing to promote, and controls ruler better.

Description of drawings:

Fig. 1 is a generalized section of the present utility model;

Fig. 2 is the structural representation of the utility model embodiment 1;

Fig. 3 is the structural representation of the utility model embodiment 2.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further specified.

Shown in Fig. 1～3, the utility model comprises ruler body 1, being generally transparent material makes, wherein, ruler body 1 lower surface forms a plurality of salient points 11, and the distribution of salient point 11 can be even, or also can be non-uniform Distribution, salient point 11 is processed into arc surfaced, helps reducing friction, is convenient to ruler and slides.The upper surface of ruler body 1 then is provided with concave surface 12 or a plurality of concave point 13 or both are provided with simultaneously, makes the easier location of finger and has controlled ruler.

The above is preferred embodiment of the present utility model, is not to be used to limit protection domain of the present utility model, and the novel structure of Fan Yiben does that simple obvious variation or equivalence modify, all should be within protection domain of the present utility model.

Claims (2)

1, a kind of novel ruler comprises ruler body (1), it is characterized in that: the lower surface of described ruler is provided with several salient points (11), and upper surface is provided with several concave surfaces (12) or concave point (13).

2, novel ruler according to claim 1 is characterized in that: described salient point (11) is an arc surfaced.
