Abstract
The invention relates to a cylinder-type ruler. The cylinder-type ruler comprises a cylinder ruler body made from transparent materials; scale lines are arranged on the inner surface of the cylinder ruler body; and rolling edges of which the external diameters are larger than the external diameter of the cylinder ruler body by 1 mm-3 mm are arranged at the two ends of the cylinder ruler body respectively. The cylinder-type ruler is not in contact with a pencil point during drawing, it is avoided that ink or pencil powder remains on the cylinder-type ruler, the ink or the pencil powder can be further and effectively prevented from polluting paper, and parallel lines can be drawn without an external tool.
Description
Technical field
The present invention relates to drawing field, refer in particular to a kind of drum type brake ruler.
Background technology
Disclose a kind of proof dirty-proof ruler in prior art 201210227254.8, comprise ruler, be provided with groove at the upper side bottom of ruler, and an inclined-plane is set on the downside of ruler body; When drawing, ink can be isolated by groove, and after completing, the inclined-plane of flicking end then makes ruler front end lift, and can effectively prevent ink trace to make dirty paper; But the ink remained on ruler or pencil end still can affect next time and draw, and need by other set square when drawing parallel lines, otherwise cannot ensure that lines are parallel, for this reason, we have developed a kind of drum type brake ruler, not contacting, not only avoid ink or pencil end remains on chi when drawing with nib, effectively can also prevent ink or pencil end to make dirty paper, and just to paint parallel lines by external tool.
Summary of the invention
The present invention seeks to provide a kind of drum type brake ruler to overcome the deficiencies in the prior art, do not contact with nib when drawing, not only avoid ink or pencil end remains on chi, can also effectively prevent ink or pencil end to make dirty paper, and just to paint parallel lines by external tool.
For achieving the above object, the technical solution used in the present invention is: a kind of drum type brake ruler, comprises the cylinder chi be made up of transparent material; The inner surface of described cylinder chi is provided with graduation mark; The two ends of described cylinder chi are respectively arranged with the rolling of 1-3mm larger than cylinder chi external diameter.
Preferably, one of them rolling of described cylinder chi is provided with the scale of circle distribution, described cylinder chi is arranged the side plate that graduated one end is also provided with bottom surface and the tangent placement of rolling; The upper end of described side plate is provided with scale marker.
Preferably, described side plate is set on the round boss of rolling outer end setting; The axis of described round boss and the dead in line of rolling.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Drum type brake ruler of the present invention does not contact with paper with nib when drawing, and not only avoid ink or pencil end remains on chi, can also effectively prevent ink or pencil end to make dirty paper, the parallel lines of pitch requirements and rotating cylinder chi can also be painted.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Accompanying drawing 1 is the structure chart of drum type brake ruler of the present invention;
Accompanying drawing 2 is the partial exploded view of drum type brake ruler of the present invention;
Accompanying drawing 3 is the operating diagram of drum type brake ruler of the present invention;
Wherein: 1, cylinder chi; 11, graduation mark; 12, rolling; 13, scale; 2, side plate; 21, scale marker.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing 1-3 is drum type brake ruler of the present invention, comprises the cylinder chi 1 be made up of transparent material; The inner surface of described cylinder chi 1 is provided with graduation mark 11, makes graduation mark 11 can keep lines and numeral clearly all the time; The two ends of described cylinder chi 1 are respectively arranged with the rolling 12 of 1-3mm larger than cylinder chi 1 external diameter, and one of them rolling 12 are provided with the scale 13 of circle distribution; The one end described cylinder chi 1 being provided with scale 13 is also provided with the side plate 2 of bottom surface and the tangent placement of rolling 12; Described side plate 2 is set on the round boss of rolling 12 outer end setting; The axis of described round boss and the dead in line of rolling 12; The upper end of described side plate 2 is provided with scale marker 21, the parallel lines of pitch requirements of being convenient to paint.
When drawing straight line: cylinder chi 1 is placed on paper, and grasps side plate 2; Now, just on cylinder chi 1, straight line can be drawn according to graduation mark 11, diameter due to rolling 12 is greater than the external diameter of cylinder chi 1, when painting, cylinder chi 1 does not contact with paper with nib, not only avoid ink or pencil end remains on chi, effectively can also prevent ink or pencil end to make dirty paper, the parallel lines and rotating cylinder chi 1 can also be painted, and cylinder chi 1 can be made to rotate suitable position by the scale marker 21 that side plate 2 is arranged to draw the parallel lines having pitch requirements.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Drum type brake ruler of the present invention does not contact with paper with nib when drawing, and not only avoid ink or pencil end remains on chi, can also effectively prevent ink or pencil end to make dirty paper, the parallel lines of pitch requirements and rotating cylinder chi can also be painted.
Below be only embody rule example of the present invention, protection scope of the present invention is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within rights protection scope of the present invention.
