Abstract
The utility model discloses a compass ruler which comprises a ruler body with scale marks, wherein a sliding slot is formed in the length direction of the ruler body; a sliding block capable of sliding along the sliding slot is arranged in the sliding slot; a center positioning pin, which extends out of the ruler body through the sliding slot and is perpendicular to the ruler body, is arranged on the sliding block; a user can use the ruler edge of the ruler body to draw a straight line, and only needs to move the sliding block in the sliding slot, move the center positioning pin to a corresponding position, press the center positioning pin, insert the pencil point of a drawing pencil into a circular through hole and rotate the ruler body to draw a circle. Therefore, the compass ruler integrates circle drawing and straight line drawing, and is simple in structure, small in size and convenient to carry.
Description
Technical field
The utility model relates to a kind of drawing instrument, relates in particular to a kind of compasses-ruler that has setting-out, draws circle.
Background technology
Ruler of the prior art only has the function of picture straight line, does not possess the function of picture circle.Compasses are comprised of rotating shaft four parts of the bull stick with needle point, bull stick with paintbrush, handle and handle below, and these compasses only have the function of picture circle, and complex structure.Want to realize picture straight line and draw circle, just must prepare ruler and these two kinds of drawing instruments of compasses, not only need to prepare corresponding larger writing case, to pack ruler and compasses into, and carry also inconvenient.
Utility model content
For above shortcomings part in prior art, the utility model provides a kind of compasses-ruler that collects picture circle, draws straight line.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
Compasses-ruler, comprise the ruler body that is provided with graduation mark, middle part at ruler body, and the length direction along ruler body is provided with chute, the slide block that setting can be slided along chute in described chute, arranges on described slide block from chute and stretches out ruler body and perpendicular to the center of circle alignment pin of ruler body; The two ends of described chute are provided with the manhole that can insert for the nib of the pen of drawing.
As a kind of preferred version of the present utility model, this compasses-ruler also comprises locking nut, on the cylindrical of described center of circle alignment pin, external screw thread is set, and one end of center of circle alignment pin is fixed on slide block, and the other end is taper; Described slide block is positioned in the one side of ruler body, and described locking nut rotation set is on the alignment pin of the center of circle and be positioned on the another side of ruler body.
As another kind of preferred version of the present utility model, the cross section of described chute is the large trapezoidal hole in outside, and described slide block is arranged in trapezoidal chute.
The beneficial effects of the utility model are: the utility model is at the middle part of ruler body, and are provided with chute along the length direction of ruler body, arrange from chute and stretch out ruler body and perpendicular to the center of circle alignment pin of ruler body on slide block; While drawing straight line, utilize the ruler limit of ruler body to draw straight line; Draw bowlder, only need be in chute moving slider, at center of circle alignment pin, move to behind corresponding position, according to center of circle alignment pin, then the nib of the pen of drawing is inserted to manhole, rotate ruler body and just can carry out picture circle, therefore, this compasses-ruler integrates picture circle, draws straight line, simple in structure, volume is little, easy to carry.
Accompanying drawing explanation
Fig. 1 is the structural representation of compasses-ruler.
In figure: 1-ruler body; 2-chute; 3-slide block; 4-center of circle alignment pin; 5-locking nut; 6-manhole; 7-alignment line.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, compasses-ruler, comprises the ruler body 1, slide block 3, center of circle alignment pin 4 and the locking nut 5 that are provided with graduation mark.At the middle part of ruler body 1, and be provided with chute 2 along the length direction of ruler body 1, the cross section of chute 2 is the large trapezoidal hole in outside.Slide block 3 is arranged in trapezoidal chute 2 and can slides along chute 2, on slide block 3, arrange from chute 2 and stretch out ruler body 1 and perpendicular to the center of circle alignment pin 4 of ruler body 1, on the cylindrical of center of circle alignment pin 4, external screw thread is set, one end of center of circle alignment pin 4 is fixed on slide block 3, the other end of center of circle alignment pin 4 is taper, tapering point is mainly used in the centering of picture bowlder, slide block 3 is positioned in the one side of ruler body 1, and locking nut 5 rotation sets are on center of circle alignment pin 4 and be positioned on the another side of ruler body 1.The two ends of chute 2 are provided with the manhole 6 that can insert for the nib of the pen of drawing.
In the upper surface of slide block 3 and the both sides that are positioned at center of circle alignment pin 4, be respectively equipped with the alignment line 7 parallel with graduation mark on ruler body 1, drawing bowlder, be conducive to center of circle alignment pin 4 location.
While using this compasses-ruler, while drawing straight line, utilize the ruler limit of ruler body 1 to draw straight line; Draw bowlder, first unscrew locking nut 5, at the interior moving slider 3 of chute 2, at center of circle alignment pin 4, move to corresponding position (alignment line 7 that is slide block 3 upper surfaces is corresponding with a certain graduation mark on ruler body 1), then screw locking nut 5, according to center of circle alignment pin 4, then the nib of the pen of drawing is inserted to manhole 6, rotate ruler body 1 and just can carry out picture circle, therefore, this compasses-ruler integrates picture circle, draws straight line, simple in structure, volume is little, easy to carry.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
