Abstract

The utility model relates to stationery and particularly relates to a transformative ruler. The transformative ruler consists of a first square ruler, a first trapezoid ruler, a second trapezoid ruler and a second square ruler, wherein the length of the hypotenuse of the first square ruler is equal to that of the left bevel edge of the first trapezoid ruler, and the 60-degree closed angle of the first square ruler is in rotating connection with the left peak of the first trapezoid ruler by virtue of a rotating member; the right base angle of the first trapezoid ruler is in rotating connection with the left base angle of the second trapezoid ruler by virtue of a rotating member, the length of the right edge of the first trapezoid ruler is equal to that of the left edge of the second trapezoid ruler, the right edge of the first trapezoid ruler and the left edge of the second trapezoid ruler are both right-angle edges, and the right apex angle of the second trapezoid ruler is in rotating connection with the 30-degree closed angle of the second square ruler by virtue of a rotating member; and the bottom edges of the first and second trapezoid rulers are equal, and the sum of the shortest edge of the first square ruler and the longest right-angle edge of the second square ruler is equal to the sum of the top edge of the first trapezoid ruler and the top edge of the second trapezoid ruler. The transformative ruler can be transformed into various measuring tools, is convenient to use and has certain beneficial effects.

Description

A kind of deformation ruler

Technical field

The utility model relates to a kind of stationery, especially a kind of deformation ruler.

Background technology

The usual amounts of student's use at present has set square, ruler, graphometer etc., but all is that single-piece is used, and all inconveniences are carried, deposit and used to function singleness.

The utility model content

The utility model is intended to address the above problem, and it is multiple measurer, deformation ruler easy to use that a kind of deformable is provided, and its technical scheme that adopts is following:

A kind of deformation ruler; Form by first square, the first trapezoidal chi, the second trapezoidal chi and second square; The left hypotenuse equal in length of the hypotenuse of said first square and the first trapezoidal chi, the 60 degree wedge angles of said first square and the left summit of the first trapezoidal chi are rotationally connected through tumbler;

The right base angle of the said first trapezoidal chi and the left base angle of the second trapezoidal chi are rotationally connected through tumbler; The right of the said first trapezoidal chi is long with the second trapezoidal chi left side appearance etc. and all be right-angle side, and 30 of the right drift angle of the said second trapezoidal chi and second square spent wedge angles and be rotationally connected through tumbler;

The said first trapezoidal chi equates that with the base of the second trapezoidal chi the minor face of said first square and the longest right-angle side sum of second square equate with the first trapezoidal chi top margin and the second trapezoidal chi top margin sum.

On the technique scheme basis, the first trapezoidal chi and the second trapezoidal chi are marked with angle measuring calibration.

The utlity model has following advantage: carry, deposit conveniently, function is many, and deformable is that multiple measurer is easy to use.

1. first square, the 2. first trapezoidal chi, the 3. second trapezoidal chi, 4. second square, 5. tumbler.

The specific embodiment

Below in conjunction with accompanying drawing and instance the utility model is described further:

Extremely shown in Figure 3 like Fig. 1; A kind of deformation ruler of present embodiment; Form by first square (1), first trapezoidal chi 2, the second trapezoidal chi 3 and second square 4; The left hypotenuse equal in length of the hypotenuse of said first square 1 and the first trapezoidal chi 2, the 60 degree wedge angles of said first square 1 and the left summit of the first trapezoidal chi 2 are rotationally connected through tumbler 5;

The left base angle of the right base angle of the said first trapezoidal chi 2 and the second trapezoidal chi 3 is rotationally connected through tumbler 5; The right of the said first trapezoidal chi 2 is long with second trapezoidal chi 3 left side appearance etc. and all be right-angle side, and 30 of the right drift angle of the said second trapezoidal chi 3 and second square 4 spent wedge angles and be rotationally connected through tumbler 5;

The said first trapezoidal chi 2 equates that with the base of the second trapezoidal chi 3 the minor face of said first square 1 and the longest right-angle side sum of second square 4 equate with first trapezoidal chi 2 top margins and the second trapezoidal chi 3 top margin sums.

Preferably, the first trapezoidal chi 2 and the second trapezoidal chi 3 are marked with angle measuring calibration.

During use, the ruler of doing as shown in Figure 1 uses, and with first square, 1 dextrorotation turnback, second square 4 is rotated counterclockwise 180 degree just can forms a square (referring to Fig. 2).Under the state of ruler, first square 1 and the first trapezoidal chi 2 are rotated counterclockwise 90 degree as a whole, with the second trapezoidal chi 3 and second square 4 as a whole dextrorotation turn 90 degrees and just can be spliced into protractor (referring to Fig. 3).

With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes done based on the utility model or modification all belong to the utility model and require the scope protected.
