Abstract

The utility model discloses a multifunctional ruler, comprising a ruler body, a scale, a scale numeric value, a round area numeric value and a parallel groove. The ruler body is made of transparent materials such as organic glass or plastics, five parallel grooves are arranged on the ruler body in longitudinal direction, the left and right end of each groove is 1 to 2cm away from the rim of the left and right end of the ruler body respectively, which facilitates drawing a plurality of parallel lines such as the four-line lattice to write letters or the five-line lattice to write musical notes; the scale and the corresponding numeric value are arranged at one side in the transparent ruler body and the round area numeric value with corresponding scale as radius is marked on the corresponding scale numeric value at the same time to avoid the wearing caused by arranging the scale and numeric value on the surface of the ruler body. The utility model is convenient, novel, wear-resisting, time-saving and efficient, which is bound to become popular among garden, architectural and mechanical designers as well as teachers and students.

Description

Multi-functional ruler

(1) technical field:

The utility model relates to the stationery of a kind of measurement, drawing, especially a kind of multi-functional ruler.

(2) background technology:

At present, Ruler for student use all is made up of chi body and scale, and is well-known, and these rulers only can help the picture straight line and survey length, but can not help people to draw many parallel lines easily, especially students in middle and primary schools write the Chinese phonetic alphabet and English letter four line lattice, write five line lattice of note etc.; In addition, its scale of known ruler and numerical value all are indicated in the chi surface, are worn away easily and do not see Chu.Moreover, when people run into a circle or surface for circular machine components, engineering material, all need to measure with ruler earlier the radius (or diameter) of disc, then by area formula of circle " S _Circle=π r ²" calculate and just can draw area, obviously delayed the working time, cumbersome again.Therefore, a lot of people especially be engaged in the staff of landscape design, architectural design, construction, mechanical drawing and numerous students in middle and primary schools more need a kind of can make things convenient for many parallel lines of picture and indicate above the chi body have area of a circle numerical value, only need to measure radius of a circle or diameter and do not need in addition again by the mathematical computations very fast ruler of directly knowing this area of a circle that just can come into plain view.

(3) utility model content:

The purpose of this utility model is: be worn easily in order to overcome existing ruler scale and numerical value, can not draw many parallel lines easily, deficiencies such as directly predicting the area of a circle can not come into plain view, the utility model provides a kind of and makes with transparent material, on the chi body, be provided with five parallel longitudinal grooves, and the inner scale that indicates of chi body, numerical value and be the multi-functional ruler of the corresponding area of a circle value of radius with this numerical value, this multi-functional ruler not only possesses the function of common ruler, and utilize the longitudinal groove on the transparent ruler body can draw many parallel lines easily, or write four line lattice of the Chinese phonetic alphabet and English letter, write five line lattice of note etc., utilization utilizes the inner area numerical value with this number of division value circle that is radius with the corresponding one by one place of scale sign of transparent ruler body, only need to measure radius of a circle, do not need to pass through mathematical computations, the very fast area numerical value of directly knowing this circle just can come into plain view again.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of multi-functional ruler comprises chi body, scale, scale numerical value, area of a circle numerical value and parallel groove.Described chi body is that transparent material such as organic glass, plastic or other material are made, and vertically is provided with five parallel grooves on the chi body, and each two ends, the groove left and right sides all keeps the 1-2cm distance with chi body left and right sides edges at two ends.

Be provided with scale and corresponding scale numerical value at the inner side of transparent ruler body, and transparent ruler body inside with the area numerical value of the scale corresponding position circle that also to indicate with this number of division value be radius, being worn easily to prevent scale and numerical value to be located at the chi surface, it is unclear to thicken.The inner set scale of transparent ruler body can be millimeter, centimetre, decimeter or meter, be that each scale is corresponding one by one in area of a circle numerical value and the scale of radius with corresponding scale.

The beneficial effects of the utility model are: with the parallel groove of pen on the chi body on paper or the other materials surface streak, many parallel lines that can draw easily, the four line lattice of writing English letter, phonetic alphabet, the five line lattice of writing note also can draw; When people need know the area of a circle, only need measure the radius of this disc with ruler, need not to calculate the area numerical value that just can directly read this circle very soon by area formula of circle again.The utility model is easy to use, and is novel wear-resisting, can save time, and raises the efficiency, and will be subjected to vast gardens, building, Machine Design teacher and numerous friend's teachers and students favor.

Embodiment of the present utility model is provided by accompanying drawing 1-2.

Fig. 1 is the front schematic view of one of the utility model embodiment.

Fig. 2 is two the front schematic view of the utility model embodiment.

Wherein, the ordinal number that is marked in the accompanying

drawing

1,2 is respectively:

1, chi body 2, scale

3, scale numerical value 4, be the area of a circle numerical value of radius with corresponding scale

5, parallel groove

(5) specific embodiment:

1-2 two embodiment that the utility model is enumerated are further described in conjunction with the accompanying drawings: a kind of multi-functional ruler comprises chi body (1), scale (2), scale numerical value (3), is the area of a circle numerical value (4) and the parallel groove (5) of radius with corresponding scale numerical value (3).Wherein chi body (1) is made for transparent material such as organic glass, plastic or other material, vertically is provided with five parallel grooves (5) on chi body (1), each groove (5) two ends, the left and right sides all with chi body (1) left and right sides edges at two ends maintenance 1-2cm distance.Scale (2) and scale numerical value corresponding with it (3) are located at the inner side of transparent ruler body (1), be the area of a circle numerical value (4) of radius simultaneously indicating with corresponding scale with scale numerical value (3) corresponding position, described area of a circle numerical value (4) but round numbers also can keep one or two or multidigit decimal more.In two preferred embodiments of the present utility model, described area of a circle numerical value (4) keeps two-decimal.
