Abstract

The utility model discloses a multifunction combined gauge ruler, and belongs to a multifunctional drawing tool. The multifunction combined gauge ruler comprises a main ruler, two positioning needles and a wire winding coil. The multifunction combined gauge ruler can draw any ellipse, and the major axis, the focal length and the focal point can be read directly; the multifunction combined gauge ruler can also draw a circle whose radius can be directly read, and can draw any polygons of triangles, squares, rectangles, rhombuses, parallelograms, etc., and the edges and the angles of the polygons can be read on the ruler as the polygons are drawn. The operations are finished by two strokes. The multifunction combined gauge ruler has the advantages of ingenious structure, convenient manufacture, flexible operation, simple structure, convenient portability, easy getting materials and accurate reading. The multifunction combined gauge ruler solves the problem that one device can not serve as multiple purposes. The multifunction combined gauge ruler can replace instruments ellipsographs, compasses, straight rulers, graphometers for devices, set squares, etc.; the multifunction combined gauge ruler draws pictures quickly.

Description

Multifunction combined gauge rule

The utility model belongs to multi-functional drawing instrument.

The instrument that can draw at present ellipse is many, if any CN85202222 announced by movable pin fixation fork, drawing pin nib, adjustment nut, universal joint, differential train and handle constitute ellipsograph and CN85201540 announced by common compasses device, winding pulley.The needle point of bipod is with holes, line is passed and an end is fixed from the hole, characteristics with common compasses and common divider, but the both is made the cost height by metal material, the making of each parts is difficult, and focus is difficult for finding, and major axis, minor axis, focal length are difficult determines that a thing can not be used more, operation inconvenience can not generally be promoted etc. during use.

The utility model provides a kind of multi-functional combination scale at above-mentioned deficiency, and its structure is by two main scales, nut, and coiled wire-wound coil, two pilot pins have protractor on one main scale, and paintbrush is formed.

Be further described below in conjunction with the structure and the enforcement of accompanying drawing utility model:

Fig. 1 is a structure accompanying drawing of the present utility model, and Fig. 2 is the expanded view of Fig. 1, and Fig. 3 is a paintbrush.As shown in Figure 1: (1) (2) are main scales, and (3) are nuts, and (4) are grooves, and (5) are coiled wire-wound coils, and (6) are fine rules, and (7) (8) are pilot pins, and (9) are protractors, and (10) are the paintbrushes that has groove.Main scale (1) is marked with scale, pilot pin (8) is fixed on the zero graduation line of main scale (1), what its edge protruded is the design of protractor (9), main scale also indicates zero graduation and the opposite scale of main scale (1), pilot pin (7) is fixed on the main scale (2) can fold near one with pilot pin (8), the coiled wire-wound coil (5) of close pilot pin (7) is entangled by a nail and is fixed on the main scale (2), also dug a dead slot (4) on the main scale (2), can be free to slide with the screw of nut (3) and to be as the criterion, the screw and the adjusting nut (3) that are fixed on the center of circle of protractor (9) can be fixing main scale (1) (2), porose on the needle point of pilot pin (7) (8), line passes from the pin hole of pilot pin (7) (8), walk around pilot pin (8) pin hole limit, wear back the pin hole of pilot pin (7) again, the back knotting forms.

Above-mentioned main scale (1) (2) and the available plastics of coiled wire-wound coil (5) or other rigid transparent materials are made, nut (3) and pilot pin (7) (8) widget can be made of metal, draw oval, bowlder, can on the graduation mark of main scale (1), read 2c along the mobile main scale of groove (4) (1) (2), 2a and radius, what pilot pin was made is exactly oval focus, in addition, can draw arbitrary triangle, square, rhombus, polygons such as parallelogram, the reading of corner can be read at the scale of scale, has solved the cost height, and it is difficult to make, reading, difficult problem focuses.

The utility model is to implement like this: a, when drawing ellipse, along the mobile main scale of groove (4) (1) (2), make the distance of pilot pin (7) (8) equal 2c, 2c can read at the scale of main scale (1), again with paintbrush (10) the drawing-down line that has groove, make vertical near main scale (1) (2), line moved to make the length of line equal 2a, reading is read on main scale (1), then be inserted into the needle point of pilot pin (7) (8) on the paper that will map fixing, grab scale and coiled wire-wound coil (5) on the other hand, map on paper with paintbrush (10) on the other hand, at this moment nib will be all the time vertical and tension fine rule (6), that two pilot pins are fixing is exactly two oval focus 1b, draw bowlder, regulate main scale (1) (2), make pilot pin (7) (8) folded tight, with paintbrush (10) backguy, make to equal radius the same 1c of other operating procedures and a, the scale of putting upside down, rotation main scale (1) (2) can be drawn arbitrary triangle, square, rectangle, rhombus, polygons such as parallelogram, polygonal angle is read by protractor (9) when painting, and reads 1d on the graduation mark of edge lengths by main scale (1) (2), by (c) mapping principle, available it carry out the cosine law, the plural number amount of asking adds, subtract, take advantage of, long-pending method and physics vector add, and relevant vector such as subtraction calculates.

Main points of the present utility model are the definition according to ellipse, and further comprehensive ellipse garden rule, compasses, set square, protractor indicate scale dexterously. Therefore, Multifunction combined gauge rule can be used to replace the instruments such as ellipsograph, compasses, set square, ruler.
