Description
Technical field
This utility model relates to map surveying technical field, a kind of novel fast precise Rectangular Drawing Rule.
Background technology
Machine plotting is an important step in map surveying work, it is simply that according to the topographic(al) point position coordinate (polar coordinate or rectangular coordinate) recorded, on drawing, the process of fixed point position, is commonly called as machine plotting.After by form point plotting fully to drawing, further according to the relation line topographic mapping between topographic(al) point.Machine plotting will pursue that speed is fast, precision is high.The topographic(al) point that a general mapping group measures for one day is the most hundreds of the most thousands of, will complete machine plotting in time, just have higher requirements machine plotting speed；It addition, certainty of measurement is the highest, if machine plotting precision is inadequate, then can directly affect topography precision, country's map surveying specification regulation, on the figure of topographic(al) point, machine plotting required precision reaches 0.1mm (unrelated with topography scale)；Improve machine plotting precision also relevant with machine plotting method, polar coordinate machine plotting compared with rectangular coordinate machine plotting, with polar coordinate machine plotting speed but precision is relatively low, with rectangular coordinate machine plotting precision is higher but speed is relatively low.Machine plotting in digitized mapping is to utilize mapping software to complete on computers, but in the map surveying practical teaching of various kinds of schools, in order to allow student's profound understanding mapping principle and grasp cartographic technique, still use analog photogrammetric plotting or Semi-digital mapping pattern, still to draw by machine plotting on drawing polyester film.
Utility model content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide one can solve fast precise Rectangular Drawing Rule, abandon two traditional chi coordinating operation machine plotting patterns and delimit the thinking of position according to scale, having solved the speed of machine plotting and the novel fast precise Rectangular Drawing Rule of precision two large problems simultaneously.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of novel fast precise Rectangular Drawing Rule, including foursquare chi plate, described chi front edge of board face is provided with the first rule, described chi plate right side is provided with the second rule, the described chi plate upper right corner is formed with the arc gap of 1/4 circular arc, described chi plate center is provided with circular hole, described chi plate upper surface, and described chi plate upper surface is provided with the grid alignd with the first rule and the second rule.
Preferably, the length and width of described chi plate are 11cm, and described chi plate thickness is 2mm, and four limits of described chi plate are provided with a millimeter groove.
Preferably, a length of 10cm of described first rule, described first rule marks to the left, and by the actual (tube) length angle value of 1: the 500 whole 10m of scale annotation；The a length of 10cm of described second rule, described second rule marks downwards, and by the actual (tube) length angle value of 1: the 500 whole 10m of scale annotation.
Preferably, the chi bottom surface arc diameter of described arc gap is 1mm, and the chi surface diameter of described arc gap is 2mm.
Preferably, a diameter of 10mm of described circular hole, described chi plate uses polythene material to make.
Owing to using technique scheme, this utility model utilizes machine plotting chi two chi limit to cross fix-point method, abandons the thinking of the scale delineation location according to a bar rule limit, makes machine plotting precision be easily reached 0.1mm requirement；Utilize the millimeter groove on machine plotting chi four limit, X, Y-coordinate value is positioned with reference to grid, replace two traditional chi coordinating operation machine plotting patterns, improve machine plotting speed, the additionally upper Direct Mark actual coordinate value of line, it is not required to again scaled distance during machine plotting and is effectively improved and pushes away chi locating speed, and then improve machine plotting speed, there is the strongest practicality simultaneously.
