Abstract
A folding airplane type graduated scale is in the shape of a polygon in the same plane when being completely unfolded, and in the shape of a paper airplane when being folded. The folding airplane type graduated scale not only has a novel shape, but also is easy to arouse study enthusiasms of school-age children; moreover, when being used for drawing graphics, the scale provides a greatly-increased number of alternative angles; and especially when being used for drawing angle equipartition lines, the scale is very convenient.
Description
Technical field:
The utility model relates to children's stationery field, relates in particular to a kind of folding aircraft-type rule interesting and practicality that has concurrently.
Background technology:
Rule is one of indispensable stationery of primary grades school-ager, and it is used to measure length, draws accurate figure aspect, and present existing rule form has vertical bar chi, set square, graphometer etc.With the set square is example, and set square of the prior art generally has the fixed angle solid shape, and it can only be used to draw smaller or equal to 3 different angles, and is functional more single.In addition, mostly the application crowd of rule is the primary grades school-ager, and this crowd's characteristics are that daily lessons pressure is big, and uninteresting study is difficult to the lasting interest of maintenance, and study is difficult to take into account with amusement.Therefore, except on course offered, teaching through lively activities, the stationery of also needing badly the school-ager improves.The utility model provides a kind of folding aircraft-type rule, and it is interesting and strengthened that it is functional that it has increased that rule uses.
The utility model content:
The technical problem that the utility model will solve is: rule of the prior art only possesses a kind of plane configuration, and it is functional single and do not possess interest.For solving the problems of the technologies described above, the utility model provides a kind of folding aircraft-type rule interesting and practicality that has concurrently, is shaped as the polygon that is in the same plane when it launches, and the shape when it is folding can be the paper helicopter shape.
The concrete technical scheme of the utility model is following:
A kind of folding aircraft-type rule; Being shaped as when it launches fully is in the polygon in the same plane; Shape when it is folding can be the paper helicopter shape; It is characterized in that: said polygon is had the angle that two adjacent side of scale are surrounded be divided into four angle-unit, with this said polygon is divided into four adjacent little triangles with common vertex, the isometric and rotatable connection of four adjacent little leg-of-mutton adjacent side; When being folded, said polygon can present multiple three-dimensional shape; Be in same plane when two adjacent side of band scale and with the adjacent separately base of this dual-side, and other side and base be when being in another plane vertical with this plane, this rule presents the shape of paper helicopter.
More preferably, the drift angle of this folding aircraft-type rule can be folded into four kinds of different angles, that is, and and an angle-unit, two angle-unit, three angle-unit and four angle-unit.
More preferably, this folding aircraft-type rule is the thin plate of being processed by the high pp material of environmental-protecting performance, but it can one-body molded also split makes bonding forming behind the little triangle.
More preferably, this folding aircraft-type rule is to make bonding forming behind the little triangle by split, said bonding be to flexibly connect, promptly in use said polygon is removable to be divided into a plurality of little triangles and to use.
More preferably, the angle that two adjacent side that this folding aircraft-type rule has scale are surrounded is 90 degree, and the angle-unit after dividing equally is 22.5 degree, and aeroplane nose forms miter angle when being folded into the paper helicopter shape.
More preferably, the angle that two adjacent side that this folding aircraft-type rule has scale are surrounded is 120 degree, and the angle-unit after dividing equally is 30 degree, and aeroplane nose forms 60 degree angles when being folded into the paper helicopter shape.
More preferably, can print the cartoon pattern on this folding aircraft-type rule.
The beneficial effect of the utility model is: the technical scheme of the utility model not only shape is novel, and when coming graphing with it, alternative angle number greatly increases, and is very convenient when especially drawing the equal separated time of angle with it.
Description of drawings:
Sketch map when Fig. 1 launches for the folding aircraft-type rule among the utility model first embodiment fully;
Sketch map when Fig. 2 is folded into the paper helicopter shape for folding aircraft-type rule shown in Figure 1;
Sketch map when Fig. 3 launches for the folding aircraft-type rule among the utility model second embodiment fully;
Sketch map when Fig. 4 is folded into the paper helicopter shape for folding aircraft-type rule shown in Figure 3.
Wherein Reference numeral is: the scale that is had on the 11-side, and the 12-fold line, the 13-angle-unit, 21-has the side of scale, 22-fold line, 23-angle-unit.
The specific embodiment:
Combine accompanying drawing that the utility model technical scheme is done further explanation at present.Be pointed out that the application's embodiment content is as to the restriction of the application's protection domain, any improvement of the utility model or protection domain that distortion all falls into the application of utilizing.
First embodiment:
The sketch map that Fig. 1 shows a kind of folding aircraft-type rule when launching fully.When launching fully, said folding aircraft-type rule is shaped as the polygon that is in the same plane; Having the angle that two adjacent side A and B of scale 11 are surrounded is 90 degree; This angle is divided into four angle-unit 13, wherein side A, the last scale that different metric can be arranged of B; With this said polygon is divided into four adjacent little triangles with common vertex, four adjacent little leg-of-mutton adjacent side 12 are isometric and be fold line.
Sketch map when Fig. 2 shows folding aircraft-type rule shown in Figure 1 and is folded into the paper helicopter shape.Folding along fold line 12, when being folded, said polygon can present multiple three-dimensional shape; Be in same plane as side A, B and with side A, base a, b that B is adjacent separately, and other side and base be when being in another plane vertical with this plane, this rule presents the shape of paper helicopter.
Second embodiment:
The sketch map that Fig. 3 shows another kind of folding aircraft-type rule when launching fully.When launching fully, said folding aircraft-type rule is shaped as the polygon that is in the same plane; Having the angle that two adjacent side A and B of scale 21 are surrounded is 90 degree; This angle is divided into four angle-unit 23, wherein side A, the last scale that different metric can be arranged of B; With this said polygon is divided into four adjacent little triangles with common vertex, four adjacent little leg-of-mutton adjacent side 22 are isometric and be fold line.
Sketch map when Fig. 4 shows folding aircraft-type rule shown in Figure 3 and is folded into the paper helicopter shape.Folding along fold line 22, when being folded, said polygon can present multiple three-dimensional shape; Be in same plane as side A, B and with side A, base a, b that B is adjacent separately, and other side and base be when being in another plane vertical with this plane, this rule presents the shape of paper helicopter.
