Abstract

The utility model discloses a structure for a universal curve plotter for children. The universal curve plotter for children is composed of a drawing template and external connection circular rings of two rotatable square bores; the external connection circular rings are fixed on the square bore of the drawing template. The universal curve plotter for children is characterized in that except for the function of the drawing template, the universal curve plotter for children can also plot and measure any angle, and is especially suitable for the children painting and plotting.

Description

Universal drawing templet for children

The utility model belongs to drawing instrument, relates to the structure of the omnipotent plotter of a kind of children's drawing, drawing usefulness.

In drawing instrument, there is a class both can measure length, but the drawing instrument of drawing geometric figures---drawing template again, great majority all have very strong drawing function, are suitable for specific application.But, drawing and measure when arbitrarily angled, all seem not very convenient, and be not suitable for children's usefulness of indiscriminately ad. as one wishes drawing.

The purpose of this utility model is exactly that drawing and measuring of proposing is arbitrarily angled in order to overcome deficiency of the prior art, and has the structure of plotter of suitable child drawing, the drawing usefulness of drawing template function.

To achieve these goals, adopt following scheme: an affixed circle caulking groove 2 in the circumscribed circle position of the square hole of the drawing template 1 that has geometric figure hole and scale; Scale is arranged around this circle caulking groove.Inlay the external annulus 3 of the square hole of two parallel folded folders in the circle caulking groove; Each annulus has the straight Beam 4 in a mistake center of circle, and the circumference of annulus can rotate in the circle caulking groove.Two straight Beam can go to any angle, and can directly read the number of degrees by the scale around the circle caulking groove.

The utility model has the advantages that: have the function of drawing template, and can draw and measure arbitrarily angled; Easy to use, be particularly suitable for child drawing, draw and use.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a schematic diagram of the present utility model;

Fig. 2 is a cutaway view of the present utility model.

Embodiment: Fig. 1 is embodiment of the present utility model, its template 1 adopts the thin rectangular slab of rigid transparent material, be carved with scale on broadside and a narrow limit thereon, a straight line that is 60 ° of angles with left narrow limit is arranged to broadside down in left upper, place, the upper right corner have a straight line that is 45 with right narrow limit under broadside; Square hole is positioned at the center of drawing template; The circle caulking groove 2 cross section be "

" shape, outside the circle caulking groove, a circle concentric with it being arranged, the lower half of circle is carved with 0 °-180 ° scale.

In an embodiment, there is a parallelogram hole on its template left side, and there are a circular hole, an elliptical aperture, a semicircle orifice and a semiellipse hole in the right.

Claims
