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 or drawing article; The assistant product group of writing or draw, circular curve are drawn or big group of analogous instrument, the little technical group field of compasses.Classification number is B43L9/02.
At present, the technology about compasses existing and that once had was all done very fruitful effort to the demand of multifunctional compass, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Hou Lejun, Granted publication number is CN2209048Y, China Patent No. (ZL) is: No. 94218158.1 utility model title is the utility model patent of " quick multifunctional drawing compasses ", the technical scheme that is adopted.At the compasses technical elements is a routine of great value invention, and it has solved the problem of compasses quick multifunctional drawing effectively.But still have some deficits, it also is difficult to the problem of the multi-functional use of solution chi.
The purpose of this utility model is to provide multifunctional compass.Problem with the multi-functional use that solves chi.
The purpose of this utility model is achieved in that this utility model multifunctional compass.Mainly constitute by chalk, fixed cover, chalkboard eraser, connecting rod I, connecting rod II, left ruler, axle, disk, axle, connecting rod III, connecting rod IV, right ruler, protractor, axle, pole, sucker.Its chalk, axle are by selecting for use on the market.Its connecting rod I, connecting rod II, connecting rod III, connecting rod IV are elongate in shape, use plastic material, through the thermoforming processing and manufacturing.Its fixed cover is a drum, uses elastomeric material, through the thermoforming processing and manufacturing.Chalk adopts embedding grammar to be installed in the interior location of fixed cover, constitutes the cylindrical shape draw bail, and function has been the effect of writing.Fixed cover adopts adhesive method to be installed in an end position of left ruler, constitutes the elongate in shape draw bail, and function has been a fixation.Connecting rod II adopts hinge method to be installed in a side position of left ruler, constitutes the elongate in shape draw bail, and function is to play supporting role.Connecting rod I adopts hinge method to be installed in an end position of chalkboard eraser, constitutes the square shape draw bail, and function is to play supporting role.Connecting rod IV adopts hinge method to be installed in an end position of left ruler, constitutes the elongate in shape draw bail, and function is to play supporting role.Connecting rod III adopts hinge method to be installed in a side position of disk, constitutes round-shaped draw bail, and function is to play supporting role.Disk adopts adhesive method to be installed in an end position of right ruler, constitutes the elongate in shape draw bail, and function is to play rotating action.Protractor adopts hinge method to be installed in the surface location of right ruler, constitutes the elongate in shape draw bail, and function has been the effect of taking measurement of an angle.Sucker adopts adhesive method to be installed in an end position of pole, constitutes the cylindrical shape draw bail, and function has been suction-operated.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has been compared two advantages and improvement with original compasses technology;
The first, because the utility model designed the protractor function in technical scheme, so can angle;
The second, because the utility model has designed the chalkboard eraser structure in technical scheme, so can erase the board; Thereby just can more effectively solve the problem of the multi-functional use of chi.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of the utility model multifunctional compass;
The numbering of parts explanation in the schematic diagram: 14 15 pole 16 suckers of 1 chalk 2 fixed covers, 3 chalkboard eraser 78 disks of 4 connecting rod I5 connecting rods, 6 left rulers 9 10 connecting rod III, 11 connecting rod IV, 12 right rulers, 13 protractors
In the optimum implementation of the utility model multifunctional compass, 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 utility model multifunctional compass.Mainly constitute by chalk 1, fixed cover 2, chalkboard eraser 3, connecting rod I4, connecting rod II5, left ruler 6, axle 7, disk 8, axle 9, connecting rod III10, connecting rod IV11, right ruler 12, protractor 13, axle 14, pole 15, sucker 16.Chalk 1 adopts embedding grammar to be installed in the interior location of fixed cover 2, constitutes the cylindrical shape draw bail, and function has been the effect of writing.Fixed cover 2 adopts adhesive method to be installed in an end position of left ruler 6, constitutes the elongate in shape draw bail, and function has been a fixation.Connecting rod II5 adopts hinge method to be installed in a side position of left ruler 6, constitutes the elongate in shape draw bail, and function is to play supporting role.Connecting rod I4 adopts hinge method to be installed in an end position of chalkboard eraser 3, constitutes the square shape draw bail, and function is to play supporting role.Connecting rod IV11 adopts hinge method to be installed in an end position of left ruler 6, constitutes the elongate in shape draw bail, and function is to play supporting role.Connecting rod III10 adopts hinge method to be installed in a side position of disk 8, constitutes round-shaped draw bail, and function is to play supporting role.Disk 8 adopts adhesive method to be bonded in an end position of right ruler 12, constitutes the elongate in shape draw bail, and function is to play rotating action.Protractor 13 adopts hinge method to be installed in the surface location of right ruler 12, constitutes the elongate in shape draw bail, and function has been the effect of taking measurement of an angle.Sucker 16 adopts adhesive method to be installed in an end position of pole 15, constitutes the cylindrical shape draw bail, and function has been suction-operated.
Its dynamic structure: in force:
According to rotary principle, its left ruler 6 acts on connecting rod III10 by connecting rod IV11, thereby finishes the task that left ruler rotates.According to the translation principle, its chalkboard eraser 3 acts on connecting rod II5 by connecting rod I4, thereby finishes the task of chalkboard eraser translation.So just realized the purpose of this utility model.Thereby just can solve the problem of the multi-functional use of chi.
Below by using method, the utility model is done more detailed description:
This utility model multifunctional compass is work like this:
In use, when using this novel, left ruler 6 and right ruler 12 can lump together by rotation, use as a long ruler, and protractor 13 can rotate by axle 14, thus the work of measuring.
In use, when using this novel, chalkboard eraser 3 can pass through the motion of connecting rod 14 and connecting rod II5, and makes it be in the operating position, finishes erasing the board of task.By adjusting the position of connecting rod III10 and connecting rod IV11, can realize that ruler is used for compasses draws round function, sucker 16 acts on the fixed position, chalk 1E and in drawing circular arc work.
Realize that preferred plan of the present utility model is is material with plastics, utilize the basic equipment of plastic processing factory, take thermoforming to produce in batch, the demand with supply student circle so just can realize practical value of the present utility model and economic worth better.
