Description

Electric blackboard eraser
The utility model relates to electric blackboard eraser.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 the cleaning device of blackboard or slabstone has the little technical group field of cleaning device of sucking chalk powder device.Classification number is B43L21/02.
At present, the technology about cleaning device that the sucking chalk powder device is arranged existing and that once had was all done very fruitful effort to the demand of electric blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China in 1996 by Gao Enji, Granted publication number is CN2235906Y, China Patent No. (ZL) is: No. 95230897.5 utility model title is the utility model patent of " electric dust absorption blackboard eraser ", the technical scheme that is adopted.At the cleaning device technical elements that the sucking chalk powder device is arranged is a routine of great value invention, and it has solved the problem of blackboard eraser electric dust absorption effectively.But still have some deficits, its also is difficult to solve, and former blackboard eraser is time-consuming, the problem of effort.
The purpose of this utility model is to provide a kind of electric blackboard eraser.Time-consuming with blackboard eraser before solving, as to require great effort problem.
The purpose of this utility model is achieved in that this utility model electric blackboard eraser.Mainly constitute by motor, right guide rail, right slide block, connecting rod, button, blackboard eraser, blackboard, left slider, left rail.Its motor, button are by selecting for use on the market.Its right guide rail, left rail are elongate in shape, use plastic material, through the thermoforming processing and manufacturing.Its right slide block, left slider are square shapes, use plastic material, through the thermoforming processing and manufacturing.Motor adopts the axle coupling method to be installed in the right positions of connecting rod, constitutes the cylindrical shape draw bail, and function is to play rotating action.Right slide block adopts clearance fit method to be installed in the outer fix of right guide rail, constitutes the elongate in shape draw bail, and function has been the slip effect.Connecting rod adopts clearance fit method to be installed in the interior location of right slide block, constitutes the elongate in shape draw bail, and function is to play rotating action.Blackboard eraser adopts adhesive method to be installed in the external position of connecting rod, constitutes the cylindrical shape draw bail, and function has been the effect of erasing the board.Left slider adopts clearance fit method to be installed in the external position of left rail, constitutes the elongate in shape draw bail, and function has been the slip effect.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 the original cleaning device technology that the sucking chalk powder device is arranged;
The first, because the utility model has designed left slider and right slide block in technical scheme, so blackboard eraser can horizontally slip;
The second, because the utility model has designed left rail and right guide rail in technical scheme, so blackboard eraser can horizontally slip; Former blackboard eraser is time-consuming, the problem of effort thereby just can more effectively solve.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of the utility model electric blackboard eraser;
The numbering of parts explanation in the schematic diagram: 1 motor, 2 right guide rail 3 right slide block 4 connecting rods 5 buttons 6 blackboard erasers 7 blackboards 8 left sliders 9 left rails
In the optimum implementation of the utility model electric blackboard eraser, 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 electric blackboard eraser.Mainly constitute by motor 1, right guide rail 2, right slide block 3, connecting rod 4, button 5, blackboard eraser 6, blackboard 7, left slider 8 left rails 9.Motor 1 adopts the axle coupling method to be installed in the right positions of connecting rod 4, constitutes the cylindrical shape draw bail, and function is to play rotating action.Right slide block 3 adopts clearance fit method to be installed in the outer fix of right guide rail 2, constitutes the elongate in shape draw bail, and function has been the slip effect.Connecting rod 4 adopts clearance fit method to be installed in the interior location of right slide block 3, constitutes the elongate in shape draw bail, and function is to play rotating action.Blackboard eraser 6 adopts adhesive method to be installed in the external position of connecting rod 4, constitutes the cylindrical shape draw bail, and function has been the effect of erasing the board.Left slider 8 adopts clearance fit method to be installed in the external position of left rail 9, constitutes the elongate in shape draw bail, and function has been the slip effect.
Its dynamic structure: in force:
According to the translation principle, its right slide block 3 acts on right guide rail 2 by slip, thereby finishes the task that right slide block slides.According to rotary principle, its connecting rod 4 acts on right slide block by motor 1, thereby finishes the task that connecting rod rotates.So just realized the purpose of this utility model.Former blackboard eraser is time-consuming, the problem of effort thereby just can solve.
Below by using method, the utility model is done more detailed description:
This utility model electric blackboard eraser is work like this:
In use, when using this novel, at first press button 5, starter motor 1 rotation, blackboard eraser 6 is because the drive of connecting rod 4 also begins rotation, then because the effect of left slider 8 and right slide block 3 makes blackboard eraser 6 downward translations, thereby finish 7 the task of erasing the board.
In use, when using this novel, the translation method is directly adopted in starter motor 1 rotation, also can finish 7 the task of erasing the board, even blackboard eraser 6 relies on the effect of left sliders 8 and right slide block 3, moves up and down, and finishes 7 the task of erasing the board.
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 educational circles so just can realize practical value of the present utility model and economic worth better.
