Abstract
The utility model relates to a coordinate drawing instrument, which is suitable for college and middle school students, and engineering staff to plot in engineering design or site operation. The coordinate drawing instrument comprises a horizontal ruler and a longitudinal ruler, and is characterized in that the middle parts of both the horizontal and the longitudinal rulers are provided with elongated grooves and integrated together by screws, wherein, both the horizontal and the longitudinal rulers are provided with pen-inserting holes, and the horizontal additionally provided with a protractor. The coordinate drawing instrument can be used as multifunctional T-square or can be used singly. The coordinate drawing instrument can achieve a plurality of drawing means, can simplify the operation process for plotting staff, and has the advantages of beautiful design, simplicity and portability.
Description
The utility model coordinate plotter is drawing, the instrument of surveying and mapping that a kind of university students and middle school students's of being suitable for study and engineers and technicians use in engineering design or site operation mapping.
Gong Ying the common instrument of surveying and mapping that is generally simple function in the market, and often need multiple instrument of surveying and mapping or means in actual use, in carrying or operating, just seeming loaded down with trivial details like this, operating efficiency can not get guaranteeing.
The purpose of this utility model is to exist weak point that a kind of coordinate plotter is provided at present common instrument of surveying and mapping, has a chi, scale, uses this plotter can reach multiple drawing means, simplify the mapping worker operating process, it is generous to be designed beautifully, and simple and direct light, function is more.
The coordinate plotter takes following scheme to realize: coordinate plotter structure has a chi, scale, present chi and scale middle part all have elongate slot, the device screw joins together, screw joins together as multi-functional T-square use after being screwedly mounted on the middle elongate slot of two chis, also can separate independent use in addition.Can be provided with serial required circle, hexagon and nut section outer contours such as M3, M4, M5, M6 on the present chi, also have several end to end variant pencils of curves.These figures of emptying at the neutral gear place of scale can be made for figure person and select to use in drawing course.The seat chi is provided with protractor, can carry out angulation or draw the angle for the illustrator.The length of seat chi all has symmetrical indentation scale to dual-side, can measure length or get the fixed length line.Present chi is provided with pen plughole, is used for a chi and uses draw circles separately, makes compasses, cuts apart rule using.Scale length is the inclined-plane to both sides, all has symmetrical scale can measure or get the fixed length line, and scale is provided with pen plughole, also can make compasses, cut apart rule using.
Seat chi and scale join the T-square that Shi Kezuo normally draws and uses together, in addition also can be according to the reality needs of drawing, and the position that changes interface can be used as the position coordinates of rectangular coordinate system with the acquisition arbitrfary point.Also can angulation or draw the angle, draw oblique line, make parallel lines etc.
The design of coordinate plotter is unique, appearance looks elegant is generous, seat chi and scale can join use together, also can use separately, use can reach multiple drawing means with this plotter, has multiple drawing, mapping function, can simplify drawing greatly, the operating process of mapping worker, this instrument is easy to use to be widely used in that the university students and middle school students draws, engineers and technicians use in engineering design or site operation mapping.This instrument can adopt transparent lucite to make as raw material, and the product distinct polishing that seems is elegant in appearance, simple and direct light.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a coordinate plotter schematic diagram.
Fig. 2 is a coordinate plotter cutaway view.
Fig. 3 is a coordinate plotter seat chi structural representation.
Fig. 4 is coordinate plotter seat chi user mode schematic diagram when making compasses.
Fig. 5 is a coordinate plotter scale structure schematic diagram.
With reference to accompanying drawing 1,2, coordinate plotter structure has a chi 4, scale 3, present chi 4 middle parts have elongate slot 6, scale 3 middle parts have elongate slot 7, seat chi and scale join together behind elongate slot by screw 1 device, nut 2 adjustment screw degrees of tightness, seat chi 4 join together as multi-functional T-square with scale 3 assemblings and use.Seat chi and scale also can use separately in addition.When seat chi and scale joined together, the coordinate plotter can obtain different functions of use, satisfied different needs to be fit to different occasions, and the specification of scale has multiple be suitable for respectively student, engineers and technicians' use in addition.Following division coordinate plotter difference in functionality: 1, make the normal T-square of drawing and using; can be linked 0 scale of seat chi 4 middle parts and scale 3 this moment by slack adjuster; tighten screw after vertical; can make T-square uses; in addition also can be according to actual figure needs; the position that changes interface can be used as rectangular coordinate system to obtain the position coordinates of arbitrfary point, can also change two chi angulations and can seek certain point.2, angulation or picture angle, picture oblique line, this moment, holder chi rotary scale can obtain the angle or the oblique line of different angles, also can directly measure the number of degrees at certain angle.3, make parallel lines, this moment, the holder chi with same angular movement scale, can be painted the pencil of parallel lines of directed distance, also can measure one group of distance between pencil of parallel lines.4, the relative position that can also change a chi and scale in addition according to actual needs obtains special needs.
With reference to accompanying drawing 1,3,4, seat chi 4 is provided with serial required circle 10, hexagon 11 and nut section outer contours 13 such as M3, M4, M5, M6, also have several end to end variant pencils of curves 14 (can make curve ruler draws), the figure that the neutral gear place of these present chis empties can be made for figure person and select to use in drawing course.Seat chi 4 is provided with 90 ° of protractors 12, can carry out angulation or draw the angle for the illustrator.Seat chi 4 length direction dual-sides all have symmetrical indentation scale, can measure length or get the fixed length line.Seat chi one end is provided with pen plughole 5.Use present chi one end pen plughole 5 that the nib of drawing pencil 8 is inserted in the hole separately with reference to accompanying drawing 4 as seat chi, in screw, plug centering pin 9 after, can make compasses and use, also can in pen plughole, insert another root the centering pin of length use as divider.
With reference to accompanying drawing 1,5, scale 3 length direction both sides are that the inclined-plane all is carved with symmetrical scale 16, can measure or get the fixed length line, scale one end has pen plughole 15, to plug centering pin in the screw in device scale elongate slot 7 in the drawing pen nib insertion hole, the same circle of painting with the seat chi is made compasses usefulness, and the same the same divider of can doing with the seat chi uses in centering pin being inserted nib hole 15.
