Abstract
The utility model provides multi-purpose compasses for drawing by the definitions of a hyperbola, an ellipse and a parabola, composed of a multi-purpose compass seat (2), an adjustable vernier (1) sheathed on the multi-purpose compass seat (2), a rotary ruler hinged on one end of the adjustable vernier (1), a rotary ruler hinged on the multi-purpose compass seat (2) and a marking pen (11) sheathed with a pinion (8). The utility model has the advantages of simple structure, convenient operation, accurate drawing and low cost of manufacture.
Description
The utility model relates to a kind of instrument of the usefulness of drawing, and especially draws hyperbola, ellipse, parabolical multigauge.
At present, the instrument of the relevant picture hyperbola paraboloid of patent applied for has tens of kinds more than, the following weak point of ubiquity: 1, structure is complicated, the manufacturing cost height; 2, use inconvenience, because the curve precision that misoperation is drawn is not high.
The purpose of this utility model is for the above-mentioned weak point that overcomes prior art provides a kind of easy to use, simple in structure, the multigauge of low cost of manufacture.
Technical solution of the present utility model is: a kind of multigauge of the usefulness of drawing, its special character is: it is by the multigauge seat, be enclosed within the adjustable vernier on the multigauge seat, be hinged on the commentaries on classics chi of adjustable vernier one end, the metal marker that is hinged on the commentaries on classics chi on the multigauge seat and is with pinion is formed, on two commentaries on classics chis inside groove is arranged all, the one side of its inside groove is a tooth bar, two tooth bars all with the pinion that is enclosed within on the metal marker, on adjustable vernier and hinged thereon commentaries on classics chi, have to make the mutually perpendicular locating hole of this two chi.
Determine the curve size for convenience, all be carved with scale on adjustable vernier of the present utility model and two commentaries on classics chis.
Because prior art has been carried out above-mentioned improvement, the utility model is not only simple in structure, low cost of manufacture, and also easy to use, draw accurately.
Below in conjunction with accompanying drawing the utility model is further described.
Front view when accompanying drawing 1 is drawn hyperbola for the utility model.
Accompanying drawing 2 is a upward view of the present utility model.
As Fig. 1, multigauge shown in Figure 2, multigauge seat (2) is cast with aluminium alloy or duroplasts, play supporting adjustable vernier (1) and change chi (3), adjustable vernier (1) inserts in the chute of multigauge seat (2), can twitch along chute, changeing chi (3) is hinged on the commentaries on classics chi support of multigauge seat (2), change on the chi (3) inside groove (4) is arranged, one side of inside groove (4) is tooth bar (5), change the end that chi (6) is hinged on adjustable vernier (1), inside groove (7) is also arranged above it, there is tooth bar (9) on one side of inside groove (7), metal marker (11) is the same with the metal marker structure of common compasses, is with modulus and tooth bar (5) in the top, (9) pinion of modulus unanimity (8), tooth bar (5), (9) mesh with pinion (8) simultaneously; Adjustable vernier (1), change chi (3) and all be carved with size scale above (6), on adjustable vernier (1) and commentaries on classics chi (6), the locating hole (10) that makes this two chi vertical is arranged.
During drawing, fixedly multigauge seat (2) promotes metal marker (11), because the wheel and rack effect, change unit of chi (3) elongation, change chi (6) unit that just contracts, according to the definition of the ellipse ellipse that just draws half, should advise then and change 180 ° of half ellipses in addition that just can draw like this.These rule are only changeed chi with one can work as the compasses use.When drawing hyperbola, will change chi (3) transposing one side, at this moment promote metal marker (11), change unit of chi (3) elongation, and change chi (6) and also extend a unit, promptly draw hyperbola.When drawing parabola, it is vertical with adjustable vernier (1) to change chi (6), will change chi (3) and take out from the hinged place of multigauge seat (2), is fixed on the selected point, promotes adjustable vernier (1), drives metal marker (11), can picture parabola.
Claims (2)
1, a kind of multigauge of the usefulness of drawing, it is characterized in that: it is by multigauge seat (2), be enclosed within the adjustable vernier (1) on the multigauge seat (2), be hinged on adjustable vernier (1) one end commentaries on classics chi (6), be hinged on the commentaries on classics chi (3) on the multigauge seat (2), and the metal marker (11) that is with pinion (8) is formed, change chi (3) and (6) inside groove (4), (7) are all arranged, the one side of its inside groove is tooth bar (5), (9), all mesh with pinion (8) tooth bar (5), (9), has to make the orthogonal locating hole of this two chi (10) on adjustable vernier (1) and commentaries on classics chi (6).
2, multigauge according to claim 1 is characterized in that: on adjustable vernier (1), commentaries on classics chi (3), (6) scale is arranged all.
