Abstract
The utility model provides a scale, which comprises a sheet body. The sheet body is rectangular, an opening is disposed inside the sheet body, three edges of the opening are n-shaped and include two parallel edges and a vertical edge vertical to the two parallel edges, and the other edge of the opening is inwards sunken to be V-shaped. Besides having functions of the existing ruler, the scale further can be used for drawing rectangles, squares, triangles, parallelograms, trapezoids and the like by aid of the three straight edges and the V-shaped sunken edge of the opening. The scale is simple in structure and convenient for carrying.
Description
Technical field
The utility model relates to a kind of stationery, especially relates to a kind of ruler of using always in how much drawing.
Background technology
In how much drawing, often can use various figures.For the drawing personnel of specialty, because the help of draughting board and present graphics software is arranged, can be than being easier to the various figures that draw.And,, rely on common ruler because instrument is limit for the student, be difficult to accurately and draw fast rectangle, square, triangle, parallelogram, trapezoidal figures.
The utility model content
At defective that exists in the prior art and deficiency, the purpose of this utility model is to propose a kind of ruler, can be accurately and the rectangle of drawing fast, square, triangle, parallelogram, trapezoidal figures as drafting instrument, and simple in structure being easy to carry.
In order to achieve the above object, the utility model proposes a kind of ruler, comprise a sheet body, described sheet noumenon is a rectangle, is provided with an opening in the described sheet noumenon; Three limits of described opening form ㄇ shapes, comprise two parallel edges that are parallel to each other and one and described two vertical edges that parallel edges is vertical; Another side forms the V font to cave inward.
Preferred as technique scheme, the equal in length of two hypotenuses of described V font, and with the equal in length of described vertical edge.
Preferred as technique scheme, the length of described two parallel edges is greater than the length of described vertical edge.
Preferred as technique scheme, the sheet noumenon of described ruler is provided with the graduation mark of warp-wise and broadwise.
The utility model proposes a kind of ruler, comprise a sheet body, described sheet noumenon is a rectangle, is provided with an opening in the described sheet noumenon; Three limits of described opening form ㄇ shapes, comprise two parallel edges that are parallel to each other and one and described two vertical edges that parallel edges is vertical; Another side forms the V font to cave inward.The utility model except that function with existing ruler, three straight flanges that can also be by opening and a V font depression limit draw easily rectangle, square, triangle, parallelogram, trapezoidal figures.And the utility model is simple in structure, be easy to carry.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.For the person of ordinary skill in the field, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
The snow shoveling machine that the utility model proposes, its preferred embodiment comprise a sheet body 1 as shown in Figure 1, and described sheet noumenon is a rectangle 1, are provided with an opening 2 in the described sheet noumenon 1; Three limits of described opening form ㄇ shapes, comprise two parallel edges that are parallel to each other and one and described two vertical edges that parallel edges is vertical; Another side forms the V font 3 to cave inward.The equal in length of two hypotenuses of described V font 3, and with the equal in length of described vertical edge.The length of described two parallel edges is greater than the length of described vertical edge.The sheet noumenon of described ruler is provided with the graduation mark of warp-wise and broadwise.
Though; the utility model clearly demonstrates by above embodiment and accompanying drawing thereof; yet under the situation that does not deviate from the utility model spirit and essence thereof; the person of ordinary skill in the field works as can make various corresponding variations and correction according to the utility model, but these corresponding variations and correction all should belong to the protection domain of claim of the present utility model.
