Abstract
The utility model relates to a surveying and mapping tool, in particular to a ruler which can be convenient for drawing straight lines, waveform lines and parallel lines and measuring angle. The combined ruler comprises a scale mark I, a rectangular hole, a scale mark II, a ruler seam, a protractor seam, a protractor, a magnifier, a line drawing hole, a blacking hole and a roller. The ruler is provided with two scales of different proportions; the rectangular hole is arranged between the scale mark I and the scale mark II; the waveform ruler seam is arranged at one side of the scale mark II; the magnifier is arranged on the protractor; the line drawing hole and the blacking hole are arranged at two sides of the protractor; and the roller is arranged at the arc side of the protractor. The combined ruler combines a common ruler with a common protractor after improvement, thus giving new functions to a geometrical tool with a single function.
Description
Technical field
The utility model relates to a kind of surveying and mapping tool, especially relates to a kind ofly can making things convenient for picture straight line, wave, parallel lines, the ruler of measuring angle.
Background technology
In daily study and work, the instrument that need use when drawing straight line, wave, parallel lines or measuring angle has: ruler, set square, protractor, compasses etc., these tool constructions are simple, function singleness, use the inconvenience of comparison.Because finish a geometric figure, often need to use multiple how much instruments.
Summary of the invention
In order to solve the above problems, the purpose of this utility model provides a kind of how much novel instruments, thereby solves present common how much inconvenient problems of instrument drawing.
To achieve the above object, the utility model has adopted following technical scheme: a kind of combination ruler, comprise graduation mark one, rectangular opening, graduation mark two, ruler seaming, protractor seaming, protractor, magnifying glass, setting-out hole, blacking hole, cylinder, described ruler is provided with the scale of twice different proportion; Have rectangular opening between graduation mark one and the graduation mark two; One side of graduation mark two is provided with the ruler seaming of undaform; Protractor is provided with magnifying glass; The protractor both sides are provided with setting-out hole and blacking hole; Protractor arc one side is provided with cylinder.
Above-mentioned ruler seaming and protractor seaming are complementary.
Above-mentioned cylinder is provided with scale.
The beneficial effects of the utility model: integrate by common ruler, protractor being improved the back, make how much single instruments of structure give new function: the protractor both sides after improvement are provided with the blacking hole, make the full-filling answering card convenient, easy like this; Protractor curved side after improvement is provided with cylinder, makes common ruler have the function of measuring curve distance like this.
When ruler separated with protractor, two kinds of how much instruments can be brought into play the effect of oneself separately: the distance of ruler energy different proportion, can draw straight line and wave; The protractor energy point of view is assisted the full-filling answering card, measures curve distance.
When ruler and protractor merged, easy to carry, except the function of drawing wave, other function was identical when separating.

Fig. 1 is that the utility model ruler separates schematic diagram with protractor.
Fig. 2 is that the utility model ruler and protractor merge schematic diagram.
Fig. 3 is the utility model ruler seaming and protractor seaming articulation port schematic diagram.
1-graduation mark one among the figure, 2-rectangular opening, 3-graduation mark two, 4-ruler seaming, 5-protractor seaming, 6-protractor, 7-magnifying glass, 8-setting-out hole, 9-blacking hole, 10-cylinder.
The specific embodiment
Below in conjunction with accompanying drawing 1-3 the specific embodiment of the present utility model is made a detailed explanation.
Embodiment: a kind of combination ruler, its structure comprise graduation mark 1, rectangular opening 2, graduation mark 23, ruler seaming 4, protractor seaming 5, protractor 6, magnifying glass 7, setting-out hole 8, blacking hole 9, cylinder 10.
The utility model divides the two large divisions: ruler after the improvement and protractor.Being provided with the twice graduation mark on the ruler after the improvement is respectively: graduation mark 1 and graduation mark 23, in the middle of the twice graduation mark, be provided with rectangular opening 2, the user is using the graduation mark 23 o'clock can setting-out in rectangular opening 2, graduation mark 231 sides are provided with undaform ruler seaming 4, can carry out interlock with protractor seaming 5 by ruler seaming 4, ruler and protractor after make improving unite two into one, and are with the straight line seaming 4 of wave also can be used for the picture wave.
On the protractor after the improvement 6, be provided with magnifying glass 7, can make presbyopia user obtain convenience like this.Be provided with blacking hole 9 and setting-out hole 8 in the both sides of protractor 6, make how much holes of full-filling answering card and picture become easy.Curved side at protractor 6 is provided with cylinder 10, makes ruler have the function of measuring curve distance.
