Abstract
The utility model relates to a pair of suction-disk teaching compasses, which belongs to the technical field of the subgroup of compasses of the group of circular curve drawing instruments or similar instruments of the subclass of writing or drawing supplies; writing or drawing auxiliary supplies of the class of writing or drawing appliances; office supplies under the subsection of printing in the section of performing operations and transporting according to the International Patent Classification (IPC). The classification number is B43L9/02. The utility model is composed of a chalk, a chalk clamp, a suction disk, a left foot, a right foot, a shaft, a bracket, a handle and a bearing. The utility model is characterized in that the bearing is arranged on the upper part position of the suction disk. The utility model is a pair of suction-disk teaching compasses with practical value.
Description
The utility model relates to the sucker educational 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, big group of circular curve plotting apparatus or 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 sucker educational compasses, also once designed many outstanding technical schemes.As being declared by Biao Shiyong of the Decree of Patent Office of China in 1996, Granted publication number is CN2242797Y, and China sharp number (ZL) is: No. 95246265.6 utility model title is the utility model patent of " Pencil compasses on desk ", 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 Pencil compasses on desk effectively.But still have some deficits, it also is difficult to solve common compasses and draws the problem that circle still has inconvenience.
The purpose of this utility model is to provide a kind of sucker educational compasses.Draw the problem that circle still has inconvenience to solve common compasses.
The purpose of this utility model is achieved in that this utility model sucker educational compasses.Mainly constitute by chalk, chalk folder, sucker, left foot, right crus of diaphragm, axle, support, handle, bearing.Its chalk, sucker, axle, bearing, by selecting for use on the market.Its chalk folder is a cylindrical shape, uses elastomeric material, through the thermoforming processing and manufacturing.Its left foot, right crus of diaphragm are elongate in shape, use aluminum alloy materials, through the mould molding processing and manufacturing.Bearing adopts the interference fit method to be installed in the upper position of sucker, constitutes the cylindrical shape draw bail, and function is to play rotating action.Bearing adopts the interference fit method to be installed in the lower end position of left foot, constitutes the cylindrical shape draw bail, and function is to play rotating action.Left foot adopts the axle coupling method to be installed in the upper end position of right crus of diaphragm, constitutes ^ shape shape draw bail, and function has been the support effect.The chalk folder adopts the thread connection method to be installed in the lower end position of right crus of diaphragm, constitutes the cylindrical shape draw bail, and function is filtration.Chalk adopts embedded method to be installed in the interior location of chalk folder, constitutes the cylindrical shape draw bail, and function has been to clamp the chalk effect.Axle is through the upper end of left foot and right crus of diaphragm, and is installed in the inside of support, forms the connection control structure of " greatly " word shape.Be used for controlling the angle of left foot and right crus of diaphragm, to reach the effect of the different circle of the radius that draws.Handle is installed in the top of support, forms one and controls structure.Effect is to be convenient to control compasses rotate.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with original compasses technology;
The first, because the utility model has designed bearing arrangement in technical scheme, so rotatable;
The second, because the utility model has designed the chalk clamping structure in technical scheme, so but the clamping chalk;
The 3rd, because the utility model has designed thread joined structure in technical scheme, so be convenient for changing part; Thereby just can more effectively solve common compasses and draw the problem that circle still has inconvenience.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure synoptic diagram of the utility model sucker educational compasses;
Fig. 2 is the partial structurtes synoptic diagram of the utility model sucker educational compasses;
The numbering of parts explanation in the synoptic diagram: 1 chalk, 2 chalks press from both sides 67 supports of 3 sucker 4 left foots, 5 rights crus of diaphragm, 8 handles, 9 bearings
In the optimum implementation of the utility model sucker educational compasses, 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 sucker educational compasses.Mainly constitute by chalk 1, chalk folder 2, sucker 3, left foot 4, right crus of diaphragm 5, axle 6, support 7, handle 8, bearing 9.Bearing 9 adopts the interference fit method to be installed in the upper position of sucker 3, constitutes the cylindrical shape draw bail, and function is to play rotating action.Bearing 9 adopts the interference fit method to be installed in the lower end position of left foot 4, constitutes the cylindrical shape draw bail, and function is to play rotating action.Left foot 4 adopts the axle coupling method to be installed in the upper end position of right crus of diaphragm 5, constitutes ^ shape shape draw bail, and function has been the support effect.Chalk folder 2 adopts the thread connection method to be installed in the lower end position of right crus of diaphragm 5, constitutes the cylindrical shape draw bail, and function is filtration.Chalk 1 adopts embedded method to be installed in the interior location of chalk folder 2, constitutes the cylindrical shape draw bail, and function has been to clamp the chalk effect.Axle 6 upper ends through left foot 4 and right crus of diaphragm 5, and be installed in the inside of support 7, form the connection control structure of " greatly " word shape.Be used for controlling the angle of left foot 4 and right crus of diaphragm 5, to reach the effect of the different circle of the radius that draws.Handle 8 is installed in the top of support 7, forms one and controls structure.Effect is to be convenient to control compasses rotate.
Its dynamic structure: in force:
According to the bearing rotary principle, its sucker 3 acts on left foot 4 by bearing 9, thereby finishes the task of rotation.According to clamping principle, its chalk 1 acts on right crus of diaphragm 5 by chalk folder 2, thereby finishes the task of chalk clamping.So just realized the purpose of this utility model.Thereby just can solve common compasses and draw the problem that circle still has inconvenience.
Below by using method, the utility model is done more detailed description:
This utility model sucker educational compasses is work like this:
In use, wait when carrying out the picture bowlder, at first chalk 1 clamping is pressed from both sides in 2 at chalk, earlier sucker 3 is fixed on circle centre position, turning handle 8 then, and chalk 1 is contacted with blackboard, will justify easily and draw.Because left foot 4 has bearing 9 structures, therefore can arbitrarily rotate.
In use, when using, if long-time the use causes chalk folder 2 to damage, because it is a thread connection with right crus of diaphragm 5, so can change rapidly, chalk 1 also can be changed at any time, uses just very convenient like this.
Realize that preferred plan of the present utility model is is material with the aluminium alloy, utilize the basic equipment of the full metalworking of aluminium factory, take mould 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.
