Abstract
The utility model belongs to stationeries, and especially relates to a multifunctional foldable ruler. The utility model includes two pieces of straightedges which have the same width and on which the scale is marked. The two straightedges are movably connected via a connecting device. The utility model is characterized in that a transparent disc which can be freely installed and disassembled is equipped on the connecting device and the 0 to 180 degrees graduation lines are symmetrically carved on the edge of the transparent disc. The utility model has all the functions of the straightedge, the set square and the protractor. Meanwhile, the utility model has the advantages that it is simple-structured and convenient for use and can be applied to the study of a plurality of pupils and middle school students.
Description
Technical field
The utility model belongs to the office stationary articles for use, relates in particular to a kind of Foldable multifunctional chi
Background technology
At present during the knowledge of students in middle and primary schools aspect how much pictures of study, generally all draw straight line with ruler, when general scale was longer, blade was also long, is not easy to carry, and when stationery rule is plastic products, is easy to fracture.At present the technical staff adopts folding two or many ruler is overcome this defective, disclosed on November 26th, 2003 as State Intellectual Property Office of the People's Republic of China, the patent No. is CN02287908.0, name is called the patented technology of folding chi, solve the problems referred to above, but had the problem of function singleness.
Summary of the invention
It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and especially is fit to the Foldable multifunctional chi that students in middle and primary schools learn to use.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be a kind of Foldable multifunctional chi, comprise two rulers that indicate scale that width is identical, two rulers flexibly connect by jockey.It is characterized in that jockey be provided with one can free installing/dismounting transparent disc, the edge symmetry of transparent disc is carved with 0～180 ° graduation mark.
The link of two rulers is semicircle; Respectively indicate a center line that is parallel to ruler on two rulers, and the extended line of two center lines intersects at the center of circle of transparent disc.
The utlity model has all functions of ruler, angle square, protractor, and had characteristics simple in structure, easy to use.
Description of drawings
Fig. 1 is that the A-A of Fig. 2 is to cutaway view.
Fig. 2 is a front view.
Fig. 3 is the utility model embodiment 1,2 structural representations.
Fig. 4 is the utility model embodiment 3 structural representations.
The specific embodiment
As shown in Figure 1, this Foldable multifunctional chi comprises that two identical 3,4, two rulers of the ruler that indicates scale 3,4 of width flexibly connect by jockey 1.It is characterized in that jockey be provided with one can free installing/dismounting transparent disc 2, the edge symmetry of transparent disc is carved with 0～180 ° graduation mark.Because the distribution of graduation mark and scale mark are prior art, be not described in detail at this.
The link of two rulers is semicircle; Respectively indicate a center line 5,6 that is parallel to ruler on two rulers 3,4, and the extended line of two center lines 5,6 intersects at the center of circle of well-illuminated disk 1.
As shown in Figure 1, 2, 3, when the requirement angle, adjust ruler 4, center line 6 is overlapped with a limit of measured angle, adjust ruler 3, center line 5 is overlapped with another limit of measured angle, adjust the scale on the transparent disc 1, make 0 degree and 180 degree graduation marks overlap with center line 6, the scale that overlaps with center line 5 is the angle of institute's angle measurement so.
As shown in Figure 1, 2, 3, when need are drawn the angle, draw straight line earlier, adjust ruler 4, center line 6 is overlapped with the institute drawing beeline, adjust the scale on the transparent disc 1, make 0 degree and 180 degree graduation marks overlap, choose graduation mark with center line 6, adjust ruler 3, graduation mark selected on center line 5 and the transparent disc 1 is overlapped,, can draw angle of departure on request with drawing straight line respectively along ruler 3,4.
Shown in Fig. 1,2,4, when the drafting straight line is long, transparent disc can be taken off, ruler 3 Rotate 180s ° can be drawn long straight line.
This use is novel to have had all functions of ruler, angle square, protractor, and has characteristics simple in structure, easy to use, is fit to numerous students in middle and primary schools and learns to use.
