Description

Multifunctional compass
The utility model relates to many kinetic energy compasses.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, the assistant product group of writing or draw, and big group of circular curve plotter or analogous instrument are drawn the little technical group field of beam compasses of great circle.Classification number is B43L9/04.
At present, existing and once had about big group of circular curve plotter or analogous instrument, draw the technology of the beam compasses group of great circle the demand of multifunctional compass all done very fruitful effort, also once designed many outstanding technical schemes.As being declared by Mai Shiyong of the Decree of Patent Office of China in 1996, Granted publication number is CN2242797Y, and China Patent No. (ZL) is: No. 95246265.6 utility model title is the utility model patent of " Pencil compasses on desk ", the technical scheme that is adopted.Big group of circular curve plotter or analogous instrument, the beam compasses group technical elements of drawing great circle is a routine of great value invention, and it has solved the problem of Pencil compasses on desk effectively.But still have some deficits, it also is difficult to solve compasses and draws the circle instability, draws fan-shaped inaccuracy, and the single problem of stationery purposes.
The purpose of this utility model is to provide a kind of multifunctional compass.Draw the circle instability to solve compasses, draw fan-shaped inaccuracy, and the single problem of stationery purposes.
The purpose of this utility model is achieved in that the multifunctional compass of this utility model.Mainly constitute by protractor, observation panel, a hole, rule, rotating shaft, handle, sucker.Its protractor is a disc-shape, uses transparent plastic material, through moulding processing and manufacturing.Its rule is rectangular strip, uses transparent plastic material, through moulding processing and manufacturing.Its rotating shaft is a cylindrical shape, uses plastic material, through moulding processing and manufacturing.Its handle is a cone shape, uses plastic material, through moulding processing and manufacturing.Its sucker is a truncated conical shape, uses plastic material, through moulding processing and manufacturing.Goniometer is connected the left position of rule by rotating shaft, constitutes the conjuncted structure of " q " word shape, and function has been the angulation effect.The lower end of rule and the protractor central authorities system of boring is passed for rotating shaft with the hole, footpath, constitutes the conjuncted structure of T-shaped shape, and function has been to connect rotary action.Sucker adopts method of attaching to be connected the upper end position of rotating shaft, constitutes the conjuncted structure of T-shaped shape, and function has been a stabilization.Handle adopts contact method to be installed in the lower end position of rotating shaft, constitutes the conjuncted structure of T-shaped shape, and function has been the effect of controlling.Observation panel adopts the method cut mill to be added in the left part position, scale opposite of rule, the limit straight line parallel of the line at the center of its bottom line and rotating shaft and rule, and function has been the effect that the observed quantity hornwork is measured.Hole adopts brill system method to bore built in the scale opposite of rule right part, and its center line and observation panel bottom line rotating shaft central point are point-blank.
The advantage of utility model: big group of the utility model and original circular curve plotter or analogous instrument, draw the beam compasses group technology of great circle and compared an advantage and improvement;
The first, because the utility model has designed protractor, rule zoarium in technical scheme, so can draw angle, circle and fan-shaped easily; Thereby just can more effectively solve compasses and draw the circle instability, draw fan-shaped inaccuracy, and the single problem of stationery purposes.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the plan structure schematic diagram of multifunctional compass of the present utility model;
Fig. 2 is the left TV structure schematic diagram of multifunctional compass of the present utility model;
The numbering of parts explanation in the schematic diagram: 3 holes of 1 protractor, 2 observation panels, 4 rules, 5 rotating shafts, 6 handles, 7 suckers
In the optimum implementation of multifunctional compass of the present 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, multifunctional compass of the present utility model.Mainly constitute by protractor 1, observation panel 2, a hole 3, rule 4, rotating shaft 5, handle 6, sucker 7.Goniometer 1 is connected the left position of rule 4 by rotating shaft 5, constitutes the conjuncted structure of " q " word shape, and function has been the angulation effect.The lower end of rule 4 and the protractor 1 central authorities system of boring are passed for rotating shaft 5 with the hole, footpath, constitute the conjuncted structure of T-shaped shape, and function has been to connect rotary action.Sucker 7 adopts method of attaching to be connected the upper end position of rotating shaft 5, constitutes the conjuncted structure of T-shaped shape, and function has been a stabilization.Handle 6 adopts contact method to be installed in the lower end position of rotating shaft 5, constitutes the conjuncted structure of T-shaped shape, and function has been the effect of controlling.Observation panel 2 adopts the method processing of cutting mill in the left part position, scale opposite of rule 4, the line at the center of its bottom line and rotating shaft 5 and the limit straight line parallel of rule 4, and function has been the effect that the observed quantity hornwork is measured.Hole 3 adopts the cap methods to bore built in the scale opposite of rule 4 right part, and its center line and observation panel 2 bottom line rotating shaft central points are point-blank.
Its dynamic structure: in force:
According to the surveying principle, its protractor 1 passes through the cooperation of rule 4, thereby finishes taking measurement of an angle of task.According to the surveying principle, its rule 4 acts on rotating shaft 5 by sucker 7, thereby finishes the task of picture circle.According to the surveying principle, its rule 4 throughput hornworks 1 act on rule 4, thereby finish the fan-shaped task of picture.So just realized the purpose of this utility model.Thereby just can solve compasses and draw the circle instability, draw fan-shaped inaccuracy, and the single problem of stationery purposes.
Below by using method, the utility model is done more detailed description:
The multifunctional compass of this utility model is work like this:
In use, in the time of needs picture angle, fixing sucking disk 7 is the center of circle, and chalk inserts a hole 3 just can draw circle on request.According to the surveying principle, its protractor 1 passes through the cooperation of rule 4, thereby finishes taking measurement of an angle of task.
In use, in the time of needs picture circle, fixing sucking disk 7 is plugged chalk and just can be drawn circle.According to the surveying principle, its quarter, virtue chi 4 acted on rotating shaft 5 by sucker 7, thereby finished the task of picture circle.According to the surveying principle, its rule 4 throughput hornworks 1 act on rule 4, thereby finish the fan-shaped task of picture.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of plastics factory, take assembling to produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
