Description
The utility model relates to multi-functional picture device.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article, writes or planning slowly and carefully assistant product group, circular curve plotter or analogous instrument technical group field.Classification number is B43L9/00.
At present, the technology about circular curve plotter or analogous instrument existing and that once had was all done very fruitful effort to the demand of multi-functional picture device, also once designed many outstanding technical schemes.As being declared by Yang Zhongkun of the Decree of Patent Office of China in 1996, Granted publication number is CN2237553Y, and China Patent No. (ZL) is: No. 95210734.1 utility model title is the utility model patent of " ellipsograph ", the technical scheme that is adopted.At circular curve plotter or analogous instrument technical elements is a routine of great value invention, and it has solved the oval-shaped problem of plotter effectively.But still have some deficits, it also is difficult to solve utilize an instrument to carry out the problem of multi-functional use.
The purpose of this utility model is to provide a kind of multi-functional picture device.Utilize an instrument to carry out the problem of multi-functional use with solution.
The purpose of this utility model is achieved in that the multi-functional picture device of this utility model.Mainly constitute by protractor, rotating disk, left side rule leg, backguy, rule point, lead for retractable pencil, right compass leg, rotating shaft, cableties.Its backguy is by selecting for use on the market.Its protractor is a semi-circular shape, uses plastic material, moulds processing and manufacturing through thermoforming.Its rotating disk is a circular shape, uses the steel material, through the punch process manufacturing.Its left side rule leg, right compass leg are the awl rod-shapes, use the steel material, through the punch process manufacturing.Its cableties are round-shaped, use the steel material, through the punch forming processing and manufacturing.Left side rule leg adopts the rotating shaft fixing means to be installed in the position of right compass leg, constitutes A shape shape compasses body structure, and function has been the effect of picture circle.Protractor adopts the rotating shaft fixing means to be installed in the position, upper strata of left side rule leg, constitutes semi-circular shape and measures structure, and function has been the effect of taking measurement of an angle.Rotating disk adopts welding method to be installed in the position, middle and upper part of right compass leg, constitutes the circular shape fixed structure, and function has been to draw the circle effect by deciding radius.Cableties adopt welding method to be installed in the lower position of left side rule leg and right compass leg, constitute round-shaped fixed structure, and function has been that the backguy effect is installed.The backguy employing is directly fastened method and is connected on the cableties.Function has been pulling rule rotary actions.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared three advantages and improvement with original circular curve plotter or analogous instrument technology;
The first, because the utility model has designed protractor in technical scheme, so can take measurement of an angle;
The second, because the utility model has designed rotating disk in technical scheme, so can draw circle according to certain radius;
The 3rd, because the utility model has designed backguy in technical scheme, so the Convenient compasses leg turns; Utilize an instrument to carry out the problem of multi-functional use thereby just can more effectively solve.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the overall appearance structural representation of the multi-functional picture device of the utility model;
The numbering of parts explanation in the schematic diagram: sharp 6 lead for retractable pencils, 7 right compass legs, 8 rotating shafts, 9 cableties of 1 protractor 2 rotating disks, 3 left side rule leg 4 backguys, 5 rule
In the optimum implementation of the multi-functional picture device of the utility model, its technical scheme is achieved in that and below in conjunction with accompanying drawing the utility model is described further:
Its static structure: as shown in the figure, the multi-functional picture device of the utility model.Mainly constitute by protractor 1, rotating disk 2, left side rule leg 3, backguy 4, rule point 5, lead for retractable pencil 6, right compass leg 7, rotating shaft 8, cableties 9.Left side rule leg 3 adopts the rotating shaft fixing means to be installed in the position of right compass leg 7, constitutes A shape shape compasses body structure, and function has been the effect of picture circle.Protractor 1 adopts the rotating shaft fixing means to be installed in the position, upper strata of left side rule leg 3, constitutes semi-circular shape and measures structure, and function has been the effect of taking measurement of an angle.Rotating disk 2 adopts welding method to be installed in the position, middle and upper part of right compass leg 7, constitutes the circular shape fixed structure, and function has been to draw the circle effect by deciding radius.Cableties 9 adopt welding method to be installed in the lower position of left side rule leg 3 and right compass leg 7, constitute round-shaped fixed structure, and function has been that the backguy effect is installed.Backguy 4 employings are directly fastened method and are connected on the cableties 9.Function has been pulling rule rotary actions.
Its dynamic structure: in force:
According to lever amplification principle, its rotating disk 2 acts on right compass leg 7 by welding method, thereby finishes by the task of rotating disk scale value as the picture circle of radius of circle.According to mechanics principle, its backguy 4 acts on right compass leg 7 by cableties 9, thereby finishes the task of laborsaving pulling rule leg.So just realized the purpose of this utility model.Utilize an instrument to carry out the problem of multi-functional use thereby just can solve.
Below by using method, the utility model is done more detailed description:
The multi-functional picture device of this utility model is work like this:
In use, when taking measurement of an angle, the top degree of measured angle is aimed in the center of circle of protractor 1, on one side concordant with 0 degree graduation mark, the graduation mark value of another side correspondence is the angle at this angle.
In use, when drawing circle by certain radius, pulling backguy is earlier rotated the rule leg, until rotating disk 2 corresponding to left side rule leg 3 on the scale value at calibration point place to be that desired radius value is scorching end, advise the circle that the leg opening angle draws with this and be desired circle.
Realize that preferred plan of the present utility model is is material with plastics, steel, utilize the basic equipment of stationery factory, take single-piece production, unite to assemble and produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
