A class number is B43L21/02. The utility model consists of a blackboard, an outer dump rail, an eraser, a pulley, a shaft, a bearing, a slide groove and an inner dump rail. The utility model is characterized in that the outer dump rail is arranged on the upper side of the blackboard and is a multifunctional eraser which is provided with utilization value.
Description
The utility model relates to multifunctional 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 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 multifunctional blackboard eraser, also once designed many outstanding technical schemes.As being declared by Wang Hongjun of the Decree of Patent Office of China in 1996, Granted publication number is CN2239896Y, and China Patent No. (ZL) is: 95245467.X number utility model title is the utility model patent of " dust-sucking eraser ", 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 of blackboard eraser dust suction effectively.But still have some deficits, it also is difficult to the problem that solution erases the board fast.
The purpose of this utility model is to provide a kind of multifunctional blackboard eraser.To solve the problem that erases the board fast.
The purpose of this utility model is achieved in that this utility model multifunctional blackboard eraser.Mainly constitute by blackboard, external slide rail, blackboard eraser, pulley, axle, bearing, chute, interior slide rail.Its bearing, chute are by selecting for use on the market.Its pulley is a disc-shape, uses plastic material, through the thermoforming processing and manufacturing.Its axle is a cylindrical shape, uses plastic material, through the thermoforming processing and manufacturing.Its interior slide rail, external slide rail are elongate in shape, use elastomeric material, through the thermoforming processing and manufacturing.External slide rail adopts adhesive method to be installed in the upper side position of blackboard, constitutes the square shape draw bail, and function is to play the guiding role.Interior slide rail adopts adhesive method to be installed in the upper side position of blackboard, constitutes the square shape draw bail, and function is to play the guiding role.Pulley adopts embedding grammar to be installed in the centre position of interior slide rail and external slide rail, constitutes the elongate in shape draw bail, and function has been the slip effect.Bearing adopts the interference fits method to be installed in the interior location of pulley, constitutes round-shaped draw bail, and function has been a rolling action.Axle adopts the interference fits method to be installed in the interior location of bearing, constitutes the cylindrical shape draw bail, and function is the action usefulness that runs up.Blackboard eraser adopts the interference fit method to be installed in the outer fix of axle, constitutes the cylindrical shape draw bail, and function has been to wipe to study usefulness.So just realized the purpose of this utility model.
The advantage of utility model: the utility model has dust suction chalk dust device technique to compare two advantages and improvement with the original dust suction chalk dust device that has;
The first, because the utility model has designed pulley in technical scheme, so can laterally slide;
The second, because the utility model has designed slide rail in technical scheme, so can be along linear slide; Thereby just can more effectively solve the problem that erases the board fast.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is agent structure master's schematic diagram of the utility model multifunctional blackboard eraser;
Fig. 2 is the partial structurtes of the utility model multifunctional blackboard eraser schematic diagrames of bowing;
The numbering of parts explanation in the schematic diagram: slide rail in 56 bearings of 1 blackboard, 2 external slide rail 3 blackboard erasers, 4 pulleys, 7 chutes 8.
In the optimum implementation of the utility model multifunctional 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 multifunctional blackboard eraser.Mainly constitute by blackboard 1, external slide rail 2, blackboard eraser 3, pulley 4, axle 5, bearing 6, chute 7, interior slide rail 8.External slide rail 2 adopts adhesive method to be installed in the upper side position of blackboard 1, constitutes the square shape draw bail, and function is to play the guiding role.Interior slide rail 8 adopts adhesive method to be installed in the upper side position of blackboard 1, constitutes the square shape draw bail, and function is to play the guiding role.Pulley 4 adopts embedding grammar to be installed in the centre position of interior slide rail 2 and external slide rail 8, constitutes the elongate in shape draw bail, and function has been the slip effect.Bearing 6 adopts the interference fits method to be installed in the interior location of pulley 4, constitutes round-shaped draw bail, and function has been a rolling action.Axle 5 adopts the interference fits method to be installed in the interior location of bearing 6, constitutes the cylindrical shape draw bail, and function is the action usefulness that runs up.Blackboard eraser 3 adopts the interference fit method to be installed in the outer fix of axle 5, constitutes the cylindrical shape draw bail, and function has been to wipe to study usefulness.
Its dynamic structure: in force:
According to rotary principle, its axle 5 acts on pulley 4 by bearing 6, thereby finishes the task that pulley rotates.According to the translation principle, its pulley 4 acts on blackboard 1 by external slide rail 2, thereby finishes the task of pulley translation.So just realized the purpose of this utility model.Thereby just can solve the problem that erases the board fast.
Below by using method, the utility model is done more detailed description:
This utility model multifunctional blackboard eraser is work like this:
In use, when using this novel, during beginning, make blackboard eraser 3 be positioned at an end of blackboard 1,1 on blackboard eraser 3 and blackboard are contacted, at this moment begin to move, because the existence of pulley 4 and interior slide rail 8 and external slide rail 2 to opposite side, make the blackboard eraser 3 can the fast moving opposite side, thereby finish 1 the task of erasing the board.
In use, when use is originally novel, owing to only need that blackboard eraser 3 is made a round trip on blackboard 1, just blackboard 1 wiping can be tried totally, therefore wipe and try the efficient height, wiping is collected in chalk dust together after trying to finish, in order to avoid fly, causes environmental pollution everywhere.
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.
