Abstract
The utility model relates to a drum formula ruler contains the drum chi of being made by transparent material, the internal surface of drum chi is provided with the scale mark, the both ends of drum chi are provided with the border than the big 1 -3mm of drum chi external diameter respectively, the utility model discloses when drawing with the nib contact, not only avoided ink or pencil end to remain on the chi, can also effectively prevent ink or the pencil end paper of making dirty, and not with the help of the outside instrument parallel lines of just painting.
Description
Technical field
The utility model relates to drawing field, refers in particular to a kind of drum type brake ruler.
Background technology
In prior art 201210227254.8, disclose a kind of proof dirty-proof ruler, comprised ruler, at the bottom of the upside of rulerPortion is provided with groove, and at ruler body downside, an inclined-plane is set; In the time drawing, groove can be isolated ink, and completesAfter, the inclined-plane of flicking end makes ruler front end lift, and can effectively prevent the ink trace paper of making dirty; But remain on rulerInk or pencil end still can affect draws next time, and draw when parallel lines need to be by other set square, otherwise cannot protectCard lines are parallel, and for this reason, we have researched and developed a kind of drum type brake ruler, in the time drawing, do not contact with nib, not only avoided inkOr pencil end remains on chi, can also effectively prevent ink or the pencil end paper of making dirty, and just can not paint by external toolParallel lines.
Utility model content
The utility model object is that a kind of drum type brake ruler is provided in order to overcome the deficiencies in the prior art, draw time notContact with nib, not only avoided ink or pencil end to remain on chi, can also effectively prevent ink or the pencil end paper of making dirty,And not by the external tool parallel lines of just painting.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drum type brake ruler, comprises by transparent materialThe cylinder chi that matter is made; The inner surface of described cylinder chi is provided with graduation mark; The two ends of described cylinder chi are respectively arranged with than circleThe rolling of the large 1-3mm of cylinder chi external diameter.
Preferably, on one of them rolling of described cylinder chi, be provided with the scale of circle distribution, on described cylinder chi, establishPut 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 with rollThe dead in line on limit.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Drum type brake ruler described in the utility model does not contact with paper with nib in the time drawing, and has not only avoided ink or leadEnd remains on chi, can also effectively prevent ink or the pencil end paper of making dirty, and the rotating cylinder chi spacing of can also having painted is wantedThe parallel lines of asking.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structure chart of drum type brake ruler described in the utility model;
Accompanying drawing 2 is the partial exploded view of drum type brake ruler described in the utility model;
Accompanying drawing 3 is the work schematic diagram of drum type brake ruler described in the utility model;
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 utility model is described in further detail.
Accompanying drawing 1-3 is drum type brake ruler described in the utility model, comprises the cylinder chi 1 of being made up of transparent material; DescribedThe inner surface of cylinder chi 1 is provided with graduation mark 11, makes graduation mark 11 can keep all the time lines and numeral clearly; Described cylinder chi1 two ends are respectively arranged with than the rolling 12 of the large 1-3mm of cylinder chi 1 external diameter, and on one of them rolling 12, are provided with circumference and divideThe scale 13 of cloth; The one end that is provided with scale 13 on described cylinder chi 1 is also provided with the side plate of bottom surface and rolling 12 tangent placements2; Described side plate 2 is set on the round boss of rolling 12 outer ends settings; The axis of the axis of described round boss and rolling 12Overlap; The upper end of described side plate 2 is provided with scale marker 21, is convenient to the parallel lines that drawing has spacing to require.
While drawing straight line: cylinder chi 1 is placed on paper, and grasps side plate 2; Now, just can be on cylinder chi 1 basisGraduation mark 11 has been drawn straight line, because the diameter of rolling 12 is greater than the external diameter of cylinder chi 1, in the time of drawing cylinder chi 1 not with nib andPaper contact, has not only avoided ink or pencil end to remain on chi, can also effectively prevent ink or the pencil end paper of making dirty, and turnMoving cylinder chi 1 parallel lines of can also painting, and it is suitable to make cylinder chi 1 rotate by the scale marker 21 arranging on side plate 2The parallel lines that have spacing to require are drawn in position.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Drum type brake ruler described in the utility model does not contact with paper with nib in the time drawing, and has not only avoided ink or leadEnd remains on chi, can also effectively prevent ink or the pencil end paper of making dirty, and the rotating cylinder chi spacing of can also having painted is wantedThe parallel lines of asking.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not formed to any limitSystem. All employing equivalents or equivalence replace and form technical scheme, all drop on the utility model rights protection scope itIn.
