Abstract
The utility model relates to a machine plotting mapping instrument. Two adjacent frames of a ruler frame of a quadrangle with right angles are respectively provided with a vernier sheet which can slide on the frame, and the vernier sheet is carved with the micro reading graduation corresponding to the graduation on the ruler frame. Each vernier sheet is provided with one end for fixing with the vernier sheet, and other end is arranged on a sliding ruler plate of the opposite frame. Each ruler plate is provided with a 'V'-shaped long slot which can penetrate through the plate surface. The centre line of a notch of the long slot is aligned with the positioned ruler plate, and is vertical with the frame of the corresponding ruler frame. The utility model has the advantages of simple operation, high precision of the measured plot point, and fast measuring speed.
Description
The utility model relates to a kind of machine plotting surveying instrument.Belong to the mapping utensil technology in the survey field.
At present, in Surveying and Mapping Industry, the existing part of the method for drafting of traditional grid square net is replaced by the computer surveying instrument.The grid square net that it is drawn not only can satisfy required precision, and has improved operating efficiency greatly.However, since present stage new technology finiteness and the complexity of surveying and mapping technology operation, can't make the machine aided drawing formation system of computer replace old-fashioned traditional operational method fully, such as plane table mapping among a small circle and the local mapping base point of repairing mapping, plotting and some coordinate plottings still need manually be used existing machine plotting tool operation, can't satisfy the problem of large scale topographical map to the machine plotting required precision but be to use existing machine plotting instrument to exist operation inconvenience when operation.
The purpose of this utility model provide a kind of simple and quick, and can determine accurately that machine plotting is to satisfy the machine plotting surveying instrument of large scale topographical map to the machine plotting required precision.
The purpose of this utility model is exactly to realize by following technical measures: a periphery indicates the right angle quadrangle chi frame of scale, on two adjacent edge frames of right angle quadrangle chi frame, being carved with and the corresponding little vernier scale sheet of reading scale of chi frame high scale of can sliding is set respectively on its frame; On each vernier scale sheet an end being set fixes with it, the chi plate that the other end can slide on its opposite side frame, on each chi plate, offer " V " shape elongate slot that chi plate plate face can be connected, and little on the notch center line of this elongate slot and the place vernier scale sheet reads to carve, and the number starting point aligns and perpendicular with the frame on the pairing chi frame.
During use, this machine plotting surveying instrument can be positioned on the chart board of need drawing, and be alignd with graticule mesh or cross hairs on the chart board in the chi angle in the chi frame, vernier scale sheet then slides, place required scale position, at this moment, the center line of the elongate slot notch in the two chi plates hangs down and to put the intersection and be the machine plotting of surveying.In the technical program, the width of elongated slots is more little, and the precision of the machine plotting of surveying is high more.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 along A-A to cutaway view.
Below in conjunction with accompanying drawing advance an explanation the utility model most preferred embodiment technical characterictic:
A kind ofly indicate the machine plotting surveying instrument that the right angle quadrangle chi frame (2) of number of division is formed by periphery.
On two adjacent edge frames of right angle quadrangle chi frame, being carved with and corresponding little vernier scale sheet (1), (5) of reading scale of chi frame high scale of can sliding on its frame is set respectively, chi plate (3), (4) that one end is fixed with it, the other end can slide on its opposite side frame are being set on each vernier scale sheet, on each chi plate, offer " V " shape elongate slot (7), (8) that chi plate plate face can be connected, and little on the notch center line of this elongate slot and the place vernier scale sheet read to carve the number starting point aligns and with the frame perpendicular on the corresponding chi frame.
In the present embodiment, for the ease of with this machine plotting surveying instrument with graticule mesh or the cross hairs in drawing align, square hornblock (6) can be set at the interior angle place of chi frame.Also manual screw (9) can be set on chi plate end.
The utlity model has simple to operate, measure machine plotting precision height, finding speed is fast Advantage.
Claims (2)
1, a kind ofly indicate the machine plotting surveying instrument that the right angle quadrangle chi frame of number of division is formed by periphery, on two adjacent edge frames of right angle quadrangle chi frame, being carved with and the corresponding little vernier scale sheet of reading scale of chi frame high scale of can sliding on its frame is set respectively, on each vernier scale sheet an end being set fixes with it, the chi plate that the other end can slide on its opposite side frame, on each chi plate, offer " V " shape elongate slot that chi plate plate face can be connected, and little on the notch center line of this elongate slot and the place vernier scale sheet read to carve the number starting point aligns and with the frame perpendicular on the corresponding chi frame.
2, machine plotting surveying instrument according to claim 1 is characterized in that and can on chi plate end manual screw be set.
