Description

Multi-functional mapping device

The utility model relates to a kind of plotting board with multiple measurement function and drawing function, especially can finish the mapping of various angles a step, the multi-functional mapping device that various leg-of-mutton mappings, length mapping, arc drafting and various parallelogram are drawn.

At present, known surveying and mapping tool commonly used has rule, set square, protractor and compasses etc., these surveying and mapping tools, function singleness separately.When drawing comparatively complicated figure, often need two or more instruments to cooperatively interact and just can finish, step is more numerous.For example, when drawing parallelogram, need the cooperation of two set squares just can finish, draw bowlder, need the cooperation of rule could determine radius of a circle, when especially the utilization hornwork is drawn angle, can not finish in a step, need three above steps just can finish at least with compasses.For example, with draw one 50 ° angle of protractor, the first step must be determined a summit and the line segment that draws, the center of circle and the bottom line of second step with protractor overlaps with drawn summit and line segment, finding 50 ° of graduation marks on the circular arc of protractor and doing mark with pen then, in the 3rd step, the mark that the summit that the first step is drawn was done with the 3rd step links up with line segment, like this, one 50 ° angle just paints.This technique of painting, not only step is many, but also is easy to cause bigger error.These number of tools are many in addition, for the user, carry and take care of all and be not easy.

Can not independently survey and draw circular arc, parallelogram and protractor and can accurately a pacing not paint various angles and various leg-of-mutton deficiency in order to overcome present survey tool, the utility model provides a kind of multi-functional mapping device, this mapping device not only has the function of length mapping, circular arc mapping and the mapping of various parallelogram, and has a mapping function and a step that step accurately finishes any angle between 0 °-360 ° and finish various leg-of-mutton mapping functions.That is, when carrying out angular surveying, tested angle value is directly indicated on angle scale by pointer; When carrying out the angle drafting, how many degree pointer points out on angle scale, just can directly this angle be painted.Multi-functional mapping device provides great convenience for numerous users, simultaneously, also very easily carries and takes care of.

The technical scheme that its technical problem that solves the utility model adopts is: on the whole by two scale pin that indicate millimeter scale, indicate 0 °---the location-plate of the semicircle angle scale of 180 ° of scales, pointer, handle, two symmetries, three parallel bars and several sections assembling dresses such as draw point, pencil-lead form.Two scale pin, but the double as rule use, possessed the mapping function of length.Two scale pin can also be installed an end of handle simultaneously jointly around the axle rotation at place, right angle, upper end on this.When two scale pin closed up fully, the angle between the bipod was 0 °, and when bipod was opened fully, the angle between the bipod was 180 °, and the angle between the bipod can be at 0 °---do between 180 ° to change arbitrarily, rotating shaft place is the summit of angle.Lower end at two scale pin is installed draw point and pencil-lead respectively, like this with the cooperation of handle, has just possessed the function of compasses.The outside two scale pin upper ends, respectively have the groove of appropriate depth, in these two grooves, the location-plate of a symmetry respectively is installed with axle, location-plate can rotate around axle separately in groove, the upper end of two location-plates is installed in the groove in the handle with axle taking the back, and also can be around to taking the axle rotation at place, when two scale pin are opened or closed up, the upper end of location-plate also can move up and down in the groove of handle when swaying.The middle and lower part of a scale outside of foot also has the groove of appropriate depth therein, in groove, get two places and two isometric parallel bars are installed with axle, two parallel bars can rotate around axle separately in groove, the other end at these two parallel bars connects with the two ends of axle with the 3rd parallel bar, these three parallel bars have just constituted parallelogram with the scale pin, when drawing back parallel bar to different position, just can obtain the different parallelogram of width, thereby can draw out various parallel four limit row.Angle scale is fixed on the surface of a scale pin, and its diameter limit overlaps with the interior straight line of scale pin, and the center of circle of angle scale is positioned at the rotating shaft part of two scale pin upper end.When two scale pin are opened or closed up, be with angle scale to rotate together.A root pointer is installed on surface at another scale pin, pointer is followed the rotation of scale pin equally and is rotated, and the effective length that pointer sways just equals the radius of angle scale, and promptly pointer reverse circular arc that sweeps on angle scale just overlaps with the circular arc of angle scale.When two scale pin close up fully, pointer should refer on 0 ° of scale of angle scale, when two scale pin are opened in line fully, pointer should refer on 180 ° of scales, promptly, open two scale pin, pointer is exactly the angle that equals between the bipod in the scale value of pointing out on the angle scale, during drawing, with pen under can be directly between the bipod this angle being drawn, not only fast but also accurate, and can utilize two scales on the scale pin to draw the length of these two adjacent sides in angle accurately, thus draw triangle fast.Thus, utilize the combination of pointer, angle scale and two scale pin, can draw out any angle between 0 °-360 ° accurately and quickly, when measuring various angles and triangle, also have same effect.The lower end of handle is coaxial with the rotating shaft of two scale pin, and the upper end is as drawing the adept of bowlder.Handle is under the effect of two location-plates, no matter what angle two scale pin open, can both guarantee that it is on the angular bisector.

The beneficial effects of the utility model are, can not only carry out the mapping of length, various circular arc and parallelogram mapping, have especially utilized the combination of pointer, angle scale and two scale pin, can survey and draw out various angles and various triangle accurately and quickly.Simple in structure, the bodily form is exquisite, be easy to carry and take care of.

Below in conjunction with accompanying drawing the utility model is further specified.
