Description
The utility model relates to the static chalkboard 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, and big group of the cleaning device of blackboard or slabstone has the little technical group field of dust suction chalk dust device.Classification number is B43L21/02.
At present, the technology about dust suction chalk dust device is arranged existing and that once had was all done very fruitful effort to the demand of static chalkboard eraser, also once designed many outstanding technical schemes.As being declared by Zhang Renbao of the Decree of Patent Office of China in 1996, Granted publication number is CN2239356Y, and China Patent No. (ZL) is: No. 94247702 utility model title is the utility model patent of " blackboard brush gathers dust ", the technical scheme that is adopted.Having aspect the dust suction chalk dust device technique is a routine of great value invention, and it has solved the problem that blackboard brush gathers dust effectively.But still have some deficits, it also is difficult to solve when erasing the board the problem that dust disorderly flies.
The purpose of this utility model is to provide a kind of static chalkboard eraser.When erasing the board with solution, the problem that dust disorderly flies.
The purpose of this utility model is achieved in that this utility model static chalkboard eraser.Mainly constitute by box body, axle I, felt, axle II, felt, lead, handle, battery case, button.Its felt, lead, button are by selecting for use on the market.Its axle I, axle II are cylindrical shapes, use stainless steel material, through the Mould Machining manufacturing.Its box body is a square shape, uses plastic material, through the thermoforming processing and manufacturing.Axle I adopts hinge method to be installed in two side positions of box body, constitutes the square shape draw bail, and function is to play rotating action.Axle II adopts hinge method to be installed in two positions of box body, constitutes the square shape draw bail, and function is to play rotating action.Felt adopts adhesive method to be installed in the outer fix of an I, constitutes the cylindrical shape draw bail, and function has been to wipe to study usefulness.Lead adopts the line method of attachment to be installed in the end positions of an II, constitutes the cylindrical shape draw bail, and function has been an electric action.Battery case adopts adhesive method to be installed in the right end position of box body, constitutes the square shape draw bail, and function has been the power supply effect.Handle adopts adhesive method to be installed in the lower position of box body, constitutes the square shape draw bail, and function has been the handle 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 dust suction chalk dust device technique that has;
The first, because the utility model has designed axle in technical scheme, so felt is rotated;
The second because the utility model designed battery case in technical scheme, so battery put and provide power supply; Thereby just can more effectively solve when erasing the board the problem that dust disorderly flies.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure schematic diagram of the utility model static chalkboard eraser;
The numbering of parts explanation in the schematic diagram: 4 II of 2 I of 1 box body, 3 felts, 5 felts, 6 leads, 7 handles, 8 battery cases, 9 buttons
In the optimum implementation of the utility model static chalkboard 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 static chalkboard eraser.Mainly constitute by box body 1, axle I2, felt 3, axle II4, felt 5, lead 6, handle 7, battery case 8, button 9.Axle I 2 adopts hinge method to be installed in two side positions of box body 1, constitutes the square shape draw bail, and function is to play rotating action.Axle II 4 adopts hinge method to be installed in two positions of box body 1, constitutes the square shape draw bail, and function is to play rotating action.Felt 3 adopts adhesive method to be installed in the outer fix of an I 2, constitutes the cylindrical shape draw bail, and function has been to wipe to study usefulness.Lead 6 adopts the line method of attachment to be installed in the end positions of an II 4, constitutes the cylindrical shape draw bail, and function has been an electric action.Battery case 8 adopts adhesive method to be installed in the right end position of box body 1, constitutes the square shape draw bail, and function has been the power supply effect.Handle 7 adopts adhesive method to be installed in the lower position of box body 1, constitutes the square shape draw bail, and function has been the handle effect.
Its dynamic structure: in force:
According to rotary principle, its felt 3 acts on box body 1 by axle I 2, thereby finishes the task that felt rotates.According to rotary principle, its felt 5 acts on box body 1 by axle II 4, thereby finishes the task that felt rotates.So just realized the purpose of this utility model.Thereby just can solve when erasing the board the problem that dust disorderly flies.
Below by using method, the utility model is done more detailed description:
This utility model static chalkboard eraser is work like this:
In use, when using this novel, hold handle 7, the one side that felt 3 will be arranged is over against blackboard, and felt 3 contacts with blackboard, and when holding handle 7 and move box body 1, felt 3 can rotate, thereby wipes the letter written with chalk on the blackboard.
In use, when using this novel, when erasing the board, press button 9, connect power supply, make an II 4 two ends have voltage to produce, thereby produce static, dust there is suction-operated, therefore chalk dust can not disorderly be flown, but concentrate on the felt 5.
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 teaching circle so just can realize practical value of the present utility model and economic worth better.
