Description

The sucked type compasses

The utility model relates to the sucked type compasses.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and the big class of office appliance is write or drawing article, the assistant product group of writing or draw, the compasses technical group field in circular curve plotter or the analogous instrument group.Be numbered B43L9/02.

At present, the technology about the compasses in circular curve plotter or the analogous instrument group existing and that once had was all done very fruitful effort to the demand of sucked type compasses, also once designed many outstanding technical schemes.As being declared by Shen Hengmao of the Decree of Patent Office of China in 1996, Granted publication number is CN223436OY, and China Patent No. (ZL) is: No. 95208124.5 utility model title is the utility model patent of " a kind of hyperbolograph ", the technical scheme that is adopted.Compasses technical elements in circular curve plotter or analogous instrument group is a routine of great value invention, and it has solved the problem of hyperbolograph effectively.But still have some deficits, it also is difficult to solution can be with the round problem of drawing with coloured chalk on blackboard.

The purpose of this utility model is to provide a kind of sucked type compasses.Can be to solve with the round problem of drawing with coloured chalk on blackboard.

The purpose of this utility model is achieved in that this utility model sucked type compasses.Mainly by main leg, screw, tiltedly leg, sucker, chalk, go up the chalk folder, the chalk folder constitutes down.Its major part chalk, screw are by selecting for use on the market.It has main leg, tiltedly leg is a rectilinear form, makes material with timber, through the machining manufacturing.Its sucker is a coniform shape, makes material with rubber, through the hot forming processing and manufacturing.Its last chalk folder and following chalk folder are rectangular shapes, make material with duroplasts, through the hot forming processing and manufacturing.The sucker employing thread connection method of its coniform shape is installed in an end of the main leg of rectilinear form, forms the thread joined structure of " T " word shape.Its following nemaline main leg adopts the screw attachment method to be installed on the oblique leg of rectilinear form.Form the screw attachment structure of " people " word shape.The last chalk folder and the following chalk folder of its rectangular shape adopt adhesive method to be installed on the oblique leg of rectilinear form.Form the adhesive structure of " F " shape.The chalk of its cylindrical shape adopts clamping means to be installed on the last chalk folder and following chalk folder of rectangular shape.Form the clamping structure of a cylindrical shape.Its sucker acts on oblique leg by main leg.Thereby make sucker satisfy the requirement that to fix main leg.Its oblique leg acts on chalk by last chalk folder and following chalk folder.Can be thereby chalk is finished in the task of blackboard upper drawing circle.So just realized the purpose of this utility model.

The technology of the compasses in the utility model and original circular curve plotter or the analogous instrument group has been compared three advantages and improvement;

The first, because the utility model designed sucker in technical scheme, can be adsorbed on problem on the blackboard so solved main leg;

The second, because the utility model has designed chalk folder and following chalk folder in technical scheme, so solved the problem that can clamp chalk;

The 3rd, because the utility model has designed main leg and oblique leg in technical scheme, can draw round problem so solved.Can be thereby just can more effectively solve with the round problem of drawing with coloured chalk on blackboard.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is a sucked type compasses main structure body schematic diagram of the present utility model;

The numbering of parts explanation in the schematic diagram: 7 times chalk folders of chalk folder on 1 main leg 2 screws 3 oblique leg 4 suckers 5 chalks 6

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, the utility model sucker type compass. Mainly by main leg 1, screw 2, oblique Leg 3, sucker 4, chalk 5, upper chalk folder 6, lower chalk folder 7 consist of. It main Part chalk 5, screw 2 are by selecting on the market. It has main leg 1, tiltedly leg 3 is straight lines Shape is made material with timber, through the machining manufacturing. Its sucker 4 is coniform shapes, Make material with rubber, through the hot forming processing and manufacturing. Its upper chalk folder 6 and lower chalk folder 7 are Rectangular shape is made material with duroplasts, through the hot forming processing and manufacturing. Its coniform shape Sucker 4 adopts the thread connection method to be installed in an end of the main leg 1 of rectilinear form, forms one The thread joined structure of " T " word shape. Its lower nemaline main leg 1 adopts screw attachment Method is installed on the oblique leg 3 of rectilinear form. Form the screw attachment of " people " word shape Structure. Upper chalk folder 6 and the lower chalk folder 7 of its rectangular shape adopt adhesive method to be installed in On the oblique leg 3 of rectilinear form. Form the adhesive structure of " F " shape. Its cylinder The chalk 5 of shape adopts clamping means to be installed in upper chalk folder 6 and the lower chalk folder of rectangular shape On 7. Form the clamping structure of a cylindrical shape. Its sucker 4 is done by main leg 1 Be used for oblique leg 3. Thereby make sucker 4 satisfy the requirement that to fix main leg 1. It tiltedly Leg 3 acts on chalk 5 by upper chalk folder 6 and lower chalk folder 7. Thereby make chalk 5 Finishing can be in the task of blackboard upper drawing circle. So just realized the purpose of this utility model. Thereby just Can solve can be with the round problem of drawing with coloured chalk on blackboard.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in use, if at the blackboard upper drawing circle, can use the utility model, earlier sucker 4 inhaled on blackboard.Zhi Haozhu leg 1 rotates oblique leg 3 usefulness screws 2 angle of main leg 1 and oblique leg 3 is fixed.Thereby on blackboard with the chalk 5 beautiful circle that draws.

Embodiment 2, in force, if chalk is long 6 service times, also can loosens and go up chalk folder 6 and following chalk folder 7, changing with the chalk of crossing 5, refill new chalk 5.It is clipped on chalk folder 6 and the following chalk folder 7.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with timber, rubber, plastics, utilize the basic equipment of compasses processing factory, take cutting, hot forming to produce in batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
