Description

Multifunctional plotter

One, technical field

The utility model relates to a kind of drawing instrument, and especially a kind of multifunctional plotter easy to use belongs to the drawing instrument technical field.

Two, background technology

Drawing instrument commonly used mainly contains compasses, ruler, circle template, protractor etc., when drawing with compasses, owing to can not accurately determine to have stayed many apertures on paper by radius of a circle, influence attractive in appearance, last coloured silk is impact effect particularly, thereby adopt the circle templates more, but the size of the drawn circle of circle template fixes, and the angle of drawing arc also can only be 90 ° a integral multiple, when drawing requires not in circle template scope, will be restricted; Though it is arbitrarily angled that protractor can be determined, its function singleness.

Three, the content of utility model

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and a kind of easy to use, multifunctional plotter attractive in appearance of drawing is provided.

For achieving the above object, the utility model is achieved in that a kind of multifunctional plotter, its special character is, it is made up of the annulus of outside and inner disk, the inboard of annulus is provided with concave station, disk places on the concave station of annulus, and can freely rotate thereon, and the radius of disk and the inside radius of annulus match; Annulus is marked with 0-360 ° graduation mark; Disk is provided with the single teeth outline that indicates graduation mark, two teeth outline, straight line, circle mould and figure commonly used.

The utility model compared with the prior art, integrate compasses, circle template, protractor, it is wide to have the drawing scope, easy to use, safe, can not destroy paper, radius is easy to determine, angle can determine arbitrarily that drafting accuracy height, drawing are totally attractive in appearance, advantage such as effective is a kind of desirable drawing instrument.

Four, description of drawings

Fig. 1 is a structural representation of the present utility model.

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

Five, the specific embodiment

For better understanding the utility model, it is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1 and Figure 2, multifunctional plotter described in the utility model mainly is made up of the annulus 1 of outside and inner disk 2, be provided with concave station 3 in the inboard of annulus 1, disk 2 places on the concave station 3 of annulus 1, and can freely rotate thereon, the inside radius of the radius of disk 2 and annulus 1 matches; Annulus 1 is marked with 0-360 ° graduation mark 4; Disk 2 is provided with single teeth outline 5, two teeth outline 6, straight line 7, circle mould 8 and the figure 9 commonly used that indicates graduation mark; Straight line 7 and teeth outline are at an angle of 90.

Draw bowlder, according to the size of circle, contrast the radius mark on single teeth outline 5, penholder is gone into suitable position, a mobile rotary disk 2 rotates thereupon can draw desired circle; When the specific circular arc of need central angle, its angle can be determined on annulus 1; Straight line 7 can be used for two limits of picture institute angle, and because of show with monodentate shape and two teeth outline all at an angle of 90, can draw in the building commonly used easily

Shape need not be added ruler during picture again, and is too small when radius, when be difficult for rotating, then can contrast round mould on the disk 2 or the circular arc close figure that draws; Because the profile of tooth on the teeth outline is different, has increased greatly and can draw round quantity and scope simultaneously, quick and convenient, the precision height.

Claims (1)

1, a kind of multifunctional plotter, it is characterized in that: form by the annulus (1) of outside and inner disk (2), the inboard of annulus (1) is provided with concave station (3), disk (2) places on the concave station (3) of annulus (1), and can freely rotate thereon, the radius of disk (2) and annulus (1) inside radius match; Annulus (1) is marked with 0-360 ° graduation mark (4); Disk (2) is provided with the single teeth outline (5) that indicates graduation mark, two teeth outline (6), straight line (7), circle mould (8) and figure (9) commonly used.
