Different distance parallel lines can be drawn by the ruler convenient for drawing parallel line, and the utility model has simple procedure, easy use and small error of the parallel lines drawn.
Description
Technical field
The utility model relates to a kind of ruler, the particularly a kind of ruler that can conveniently draw parallel lines.
Background technology
In measuring engineering and students' work, need to draw in a large number the parallel lines of different spacing at present.Drawing parallel lines in the prior art is to use common ruler, draws a straight line earlier, measures corresponding parallel lines spacing to determine 2 different points, with another straight line of two dot-dash of determining apart from this straight line with equidirectional again.Such ruler uses complex steps when drawing parallel lines, the parallel lines error that marks is bigger.
Summary of the invention
The technical problems to be solved in the utility model is aimed at the defective that common ruler is drawn parallel lines in the present technology, and the utility model provides a kind of ruler that can conveniently draw parallel lines, and it is simple to draw the parallel lines step with this ruler, and the parallel lines error of drawing is less.
The technical solution adopted in the utility model is:
Can conveniently draw the ruler of parallel lines, comprise main scale, it is characterized in that having a columned rotation rule, respectively there is the cylindric roller of a coaxial equal diameters at the two ends of rotation rule, the diameter of roller is not less than the diameter of rotation rule, the central axis and the main scale upper edge line parallel of rotation rule and roller, the axle of roller links to each other with main scale by jockey.
The ruler that can conveniently draw parallel lines of the present utility model, the roller at its rotation rule two ends can contact with the scope of operation simultaneously to produce and roll in the main scale translation, the length that its roller rolling turns over is identical with the length distance of main scale translation, therefore can in rotation rule range, draw the parallel lines of different spacing, the method of drawing like this is simple with respect to the prior art step, easy to use, the parallel lines error that marks is little, and this ruler that can conveniently draw parallel lines has kept the function of common ruler in the prior art.
Description of drawings
Fig. 1 is the schematic diagram that the utility model can conveniently be drawn the ruler of parallel lines.
Fig. 2 is the rotation rule helical form graduation mark schematic diagram of the utility model ruler that can conveniently draw parallel lines.
Fig. 3 is the closed graduation mark schematic diagram of the rotation rule of the utility model ruler that can conveniently draw parallel lines.
The specific embodiment
Describe embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram that the utility model can conveniently be drawn the ruler of parallel lines.Among Fig. 1, columned rotation
Respectively there is the cylindric roller 4 of a coaxial equal diameters at rule 3 two ends, the diameter of roller 4 is not less than the diameter of rotation rule 3, the central axis and the main scale upper edge line parallel of rotation rule 3 and roller 4, the axle of roller 4 links to each other with main scale 1 by jockey 5.When main scale 1 on the scope of operation during translation, roller 4 contacts with the scope of operation and produces rolling movement, and the distance of main scale 1 translation and roller 4 distance that turns over of rolling equates.
Described jockey 5 can be of being provided with of the outer surface of rotation rule 3 and the housing of main scale 1 one, and the axle of roller 4 links to each other with this housing, and housing exposes roller 4 and contact formed straight line with the scope of operation, contacts with the scope of operation with assurance roller 4; Described jockey 5 also can be two Extendible flakes that extend to rotation rule 3 directions from main scale 1, and the axle of roller 4 links to each other with this Extendible flake.
Among Fig. 1 label be 6 expressions be a kind of indicating device of scale value of indicating rotation rule 3.Described indicating device 6 can be parallel with main scale top along the line 2 on a housing index line, the mode indicating graduation value that coincides with the separator bar 71 of index line and graduation mark 7; Described indicating device 6 also can be pointer being provided with on the Extendible flake or an index line parallel with main scale top along the line 2, aims at the mode of separator bar 71 of graduation mark 7 or the mode indicating graduation value that the separator bar 71 of index line and graduation mark 7 coincides with pointer.
When utilizing the ruler that conveniently to draw parallel lines of the present utility model to draw parallel lines, main scale top along the line 2 along main scale 1 draws a straight line earlier, simultaneously indicating device 6 is aimed at the separator bar 71 of some scale values, afterwards with the main scale translation, after indicating device 6 indication rollers 4 turn over corresponding parallel lines spacing, stop the translation of main scale 1 and the rotation of roller 4, draw another straight line this moment along the line again along the main scale top, this straight line be the pair of parallel line that satisfies operating condition last time along main scale top straight line along the line 2 strokes.
Two rollers 4 of the utility model are tangent in same direction and main scale 1 plane, when main scale translation this moment and roller roll, can guarantee that the main scale plane and the scope of operation are docile and obedient; When two rollers 4 not with main scale 1 plane when tangent, can guarantee that also ruler draws the operate as normal of parallel lines.
Below describe the utility model and can conveniently draw two kinds of specific embodiment of rotation rule 3 graduation marks of the ruler of parallel lines.Fig. 2 is the schematic diagram of helical form graduation mark 7.Among Fig. 2, the helical form graduation mark is labeled in rotation rule outer surface, the pitch of helical form graduation mark equates, the scale value of helical form graduation mark mark should be converted into the scale value of corresponding rolling wheel, relation therebetween is: roller 4 rotates a circle and is equivalent to mobile π D length (D is the diameter of roller), and the separator bar 71 of helical form graduation mark 7 should be designated as and turn over π D length at this moment.
The second way of rotation rule 3 graduation marks that the utility model can conveniently be drawn the ruler of parallel lines is closed graduation marks 7, and Fig. 3 is its schematic diagram.Among Fig. 3, closed graduation mark is labeled in rotation rule outer surface, and closed graduation mark is the circle in the plane that is in rotation rule axis normal, and the scale value of closed graduation mark mark is converted into corresponding main scale displacement by the principle of epimere description.These closure graduation mark 7 labeling methods are simple, but when the parallel lines spacing surpasses above-mentioned π D length, the number that the scale value of mark should turn over reference to total cut-off rule 71 simultaneously.
