Abstract

The utility model relates to a dotting type multifunctional quick drawing device, which is a quick drawing device which belongs to a drawing tool. The dotting type multifunctional quick drawing device is composed of two parts of a straight board and a small circular board. The small circular board and the straight board are both provided with regular small circular holes and the position of a circular ring on the straight board is provided with the scales of angles. The utility model integrates the functions of a straight ruler, a triple straight ruler, a protractor and a compass and can satisfy the various drawing needs of persons with the combination of the reason that 'the connecting line or the track of dots can form a pattern'. The utility model has the advantages of simple structure, quick operation, convenience and low cost.

Description

The multi-functional quick drawing instrument of spot hole type

The utility model relates to a kind of device of QuickDraw, belongs to drawing tool.

Present existing drawing tool is a lot, drawing a figure usually needs several drawing tools to be used, and the multi-functional system section plate that has can only be drawn the figure of fixed size, though the drawing tool that has can be done the figure that differs in size, even can accurately map, but speed is affected.And may not always need accurate mapping on the students ' actual situation, as long as qualitative mapping of energy and plotting speed are just passable soon.The utility model integrates ruler, set square, protractor, compasses, in conjunction with the reason of " track of the line of point or point is formed figure ", can satisfy people's this mapping needs.

The purpose of this utility model is to design a kind of QuickDraw device.

The utility model is achieved in that it has two parts to constitute, straight plate and little plectane, one end of straight plate is an annulus, the other end is a rectangle part, is carved with a plurality of little squares on the little plectane, and foursquare each angle is a small sircle hole, angle index is arranged on the annulus, interior circle is gone up fluted, and little plectane is set in the interior round recessed of annulus, and little plectane can rotate in annulus; Three peripheries in addition of straight plate have length scale and angle mark line respectively, and small sircle hole is arranged respectively on the mark line, and a plurality of little squares are carved with at the middle part of straight plate, and foursquare each angle is a small sircle hole.

The utility model compared with prior art has following characteristics, 1) the made figure of the utility model mostly be the point line or the track of point make, its drawing is fast self-evident, 2) it has only two parts to constitute, and every part is all easily made, and it is simple in structure, cost is low, easily promotes the use of.

Be elaborated below in conjunction with accompanying drawing:

Fig. 1 is a front view.

Fig. 2 is a partial sectional view.

As can be seen from the figure, the utility model has two parts to constitute, straight plate 1 and roundlet plate 9, roundlet plate 9 are set in the interior groove of annulus, and roundlet plate 9 can rotate in annulus, porous 6 is arranged on it, when wanting to draw bowlder, nib is put into the rotation of a certain hole get final product, be carved with angle index 2 on the annulus, as long as aim at the center of circle and the straight line of crossing the center of circle, can draw when needing the picture angle; Mobilizable block tongue 10 is arranged on the annulus, it has played the purpose that prevents that roundlet plate 9 from coming off, other three limits on the straight plate can be used as ruler, on length scale 7 and

angle mark line

3,4,5 commonly used are arranged, porose on the angle mark line, 60 ° of angle mark lines 3 are corresponding with 30 ° of angle mark lines 4,45 scale designation line is corresponding with 45 scale designation line 5, so formed isosceles right triangle, with 60 ° of angle right angled triangles, there are many apertures 6 at the middle part of straight plate, and the aperture place also has a coordinate 8 in length and breadth, its two vertical reference axis of can easily drawing.The utility model can be drawn straight line, circle, the coordinate system of different size easily, various figures such as various triangles, various general or special polygon.

Claims

1, the multi-functional quick drawing instrument of spot hole type, constitute by straight plate 1 and roundlet plate 9, its middle straight-plate one end is an annulus, the other end is a rectangle part, it is characterized in that: be carved with a plurality of little squares on the roundlet plate 9, on foursquare each angle aperture 6 is arranged, angle index 2 is arranged on the annulus, interior circle is gone up fluted, roundlet plate 9 is set in the interior groove of annulus, and three peripheries in addition of straight plate have length scale 7 and angle mark line commonly used 3,4,5 respectively, and small sircle hole is arranged on the mark line, a plurality of little squares are carved with at the middle part of straight plate, and foursquare each angle is a small sircle hole 6.

2, quick drawing instrument according to claim 1 is characterized in that: there are two vertical reference axis 8 at small sircle hole 6 places at straight plate 1.

3, speed according to claim 1 and 2 is only painted, and it is characterized in that: movable block tongue 10 can be arranged on large circle, and block tongue 10 can be fixed little plectane.
