Abstract

The utility model relates to a pair of multi-functional compasses, which consists of a graduated scale, a slideway, a base I, a rubber pad, a base II, a pen cap, a chalk hole I, a chalk hole II, internal threads. The utility model is characterized in that the rubber pad is arranged at the bottom of the base I.. The multi-functional compasses have very practical value.

Description

Multifunctional compass
The utility model relates to multifunctional compass.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 drawing article; The assistant product group of writing or draw, big group of circular curve plotter or analogous instrument, the little technical group field of compasses.Classification number is B43L9/02.
At present, existing and once had about big group of circular curve plotter or analogous instrument, the technology of compasses group was all done very fruitful effort to the demand of multifunctional compass, 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, compasses group technical elements is a routine of great value invention, and it has solved the problem of Pencil compasses on desk effectively.But still have some deficits, the compasses function singleness before it also is difficult to solve is not easy to carry inconvenient problem with use.
The purpose of this utility model is to provide a kind of multifunctional compass.To solve former compasses function singleness, be not easy to carry inconvenient problem with use.
The purpose of this utility model is achieved in that the multifunctional compass of this utility model.Mainly constitute by rule, slideway, base I, rubber cushion, base II, the pen cap, chalk hole I, chalk hole II, internal thread.Its rule, rubber cushion are by selecting for use on the market.Its slideway, base I, base II, the pen cap are T shape shapes, use plastic material, through the injection moulding processing and manufacturing.Its chalk hole I, chalk hole II are cylindrical shapes, through the boring processing and manufacturing.Its internal thread is a screw thread form, through the processing and manufacturing of hinge silk.Slideway adopts cutting method to be installed in the centre position of rule, constitutes the rectangular shape slideway structure, and function is to play the role of positioning.Base I adopts rubbing method to be installed in the inner side of slideway, constitutes T shape shape, and function is to play the role of positioning.Rubber cushion adopts rubbing method to be installed in the lower end position of base I, constitutes round-shaped adsorption structure, and function has been suction-operated.Base II adopts rubbing method to be installed in the inner side of slideway, constitutes T shape shape, and function is to play the role of positioning.The pen cap adopts screw method to be installed in the lower end position of base II, constitutes T shape shape, and function has been to put the pen effect.Chalk hole I adopts boring method to be installed in the lower end position of the pen cap, constitutes inner hole structure, and function is to play the role of positioning.Chalk hole II adopts boring method to be installed in the right end position of the pen cap, constitutes inner hole structure, and function is to play the role of positioning.Internal thread adopts hinge silk method to be installed in the upper end position of the pen cap, constitutes the screw thread form inner hole structure, and function has been the connection effect.So just realized the purpose of this utility model.
The advantage of utility model: big group of the utility model and original circular curve plotter or analogous instrument, compasses group technology has been compared two advantages and improvement;
The first, because the utility model has designed rubber cushion in technical scheme, thus easy to use, convenient disassembly;
The second, because the utility model has designed slideway in technical scheme, so can be convenient to the location; Thereby the compasses function singleness before just more effectively having solved is not easy to carry inconvenient problem with use.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the main TV structure schematic diagram of multifunctional compass of the present utility model;
Fig. 2 is the rubber cushion structural representation of multifunctional compass of the present utility model;
Fig. 3 is the pen cap structural representation of multifunctional compass of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 rule, 2 slideways, 3 base I, 4 rubber cushions, the 5 base II6 pens cap, 7 chalk hole I, 8 chalk hole II 9 internal threads
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 rule 1, slideway 2, base I 3, rubber cushion 4, base II 5, the pen cap 6, chalk hole I 7, chalk hole II 8, internal thread 9.Slideway 2 adopts cutting method to be installed in the centre position of rule 1, constitutes the rectangular shape slideway structure, and function is to play the role of positioning.Base I3 adopts rubbing method to be installed in the inner side of slideway 2, constitutes T shape shape, and function is to play the role of positioning.Rubber cushion 4 adopts rubbing method to be installed in the lower end position of base I 3, constitutes round-shaped adsorption structure, and function has been suction-operated.Base II 5 adopts rubbing method to be installed in the inner side of slideway 2, constitutes T shape shape, and function is to play the role of positioning.The pen cap 6 adopts screw method to be installed in the lower end position of base II 5, constitutes T shape shape, and function has been to put the pen effect.Chalk hole I7 adopts boring method to be installed in the lower end position of the pen cap 6, constitutes inner hole structure, and function is to play the role of positioning.Chalk hole II 8 adopts boring method to be installed in the right end position of the pen cap 6, constitutes inner hole structure, and function is to play the role of positioning.Internal thread 9 adopts hinge silk method to be installed in the upper end position of the pen cap 6, constitutes the screw thread form inner hole structure, and function has been the connection effect.
Its dynamic structure: in force:
Its chalk acts on the pen cap 6 by chalk sleeve I 7, thereby finishes the task of picture circle.So just realized the purpose of this utility model.Thereby the compasses function singleness before just having solved is not easy to carry inconvenient problem with use.
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, when drawing circle, rubber cushion 4 is inhaled on blackboard, its chalk acts on the pen cap 6 by chalk sleeve I 7, thereby finishes the task of picture circle.
In use, when being used as ruler, base I3, base II5 can be unloaded.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of stationery factory, take to produce by batch in a large number, the demand with supply stationery circle so just can realize practical value of the present utility model and economic worth better.
