The utility model is characterized in that the spherical hinge is installed on the back face of the blackboard eraser, the end head of the telescopic handle is connected to the spherical hinge, and the net type eraser hair slice can be connected to the blackboard eraser hairs. The utility model is a multifunctional blackboard eraser with the large practical value.

Description

Multifunctional blackboard eraser

The utility model relates to multifunctional blackboard eraser.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and 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, the cleaning device technical group field of blackboard or slabstone.Be numbered B43L 21/00.

At present, the technology about the cleaning device of blackboard or slabstone existing and that once had was all done very fruitful effort to the demand of the cleaning appliance of blackboard, also once designed many outstanding technical schemes.As being declared by Huang Zhiqiang of the Decree of Patent Office of China in 1996, Granted publication number is CN2218660Y, and China Patent No. (ZL) is; 94230907.3 number the utility model title be the utility model patent of " dustproof eraser and chalk holder ", the technical scheme that is adopted.Cleaning device technical elements at blackboard or slabstone is a routine of great value invention, and it solves effectively, the problem of combination of dust reduction capability of eraser and chalk holder.But still have some deficits the problem of the multifunction when remote use of its also very difficult solution blackboard eraser and dedusting are used.

The purpose of this utility model is to provide a kind of multifunctional blackboard eraser.The problem of the multifunction when using with the remote use that solves blackboard eraser and dedusting.

The purpose of this utility model is achieved in that this utility model multifunctional blackboard eraser.Mainly constitute by blackboard eraser, ball pivot, Telescopic handle, blackboard eraser hair, net formula snag sheet.Its major part blackboard eraser hair, net formula snag sheet, ball pivot are by selecting for use on the market.The hard plastics injection moulding processing and manufacturing of blackboard eraser, Telescopic handle.A ball pivot is installed at the back side of blackboard eraser, and the termination of Telescopic handle is installed and connected in ball pivot, and the front pasting boards snag of blackboard eraser becomes striated to distribute, and net formula snag sheet can be in succession on the blackboard eraser hair, and the blackboard eraser hair also is the snag of net formula, ball pivot space 180 degree, rotation arbitrarily.So just realized the purpose of this utility model.

The utility model has been compared two advantages and improvement with the original blackboard or the cleaning device technology of slabstone;

The first, because the utility model has designed net formula snag sheet in technical scheme, can be connected on the blackboard eraser hair, enlarged usable floor area;

The second, because the utility model has designed Telescopic handle in technical scheme, enlarged the opereating specification of using.Thereby just can more effectively solve the problem of the remote use of blackboard eraser and the dedusting multifunction when using.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the plan structure schematic diagram of the utility model multifunctional blackboard eraser;

Fig. 2 is the structural representation of looking up of the utility model multifunctional blackboard eraser;

Fig. 3 is the hard straight state work structuring schematic diagram of the utility model multifunctional blackboard eraser;

The numbering of parts explanation in the schematic diagram: (1) blackboard eraser (2) ball pivot (3) Telescopic handle (4) blackboard eraser hair (5) net formula snag sheet

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

As shown in the figure, the utility model multifunctional blackboard eraser. Mainly by blackboard eraser (1), ball pivot ( 2), Telescopic handle (3), blackboard eraser hair (4), net formula snag sheet (5) consist of. Its major part Blackboard eraser hair (4), net formula snag sheet (5), ball pivot (2) are by selecting on the market. Blackboard eraser (1 ), Telescopic handle (3) makes with the hard plastics injection molding. Install at the back side of blackboard eraser (1) A ball pivot (2), the termination of Telescopic handle (3) is installed and connected in ball pivot (2), blackboard eraser (1) Front pasting boards snag (4) become striated to distribute, net formula snag sheet (5) can be in succession in the blackboard eraser hair (4) on, blackboard eraser hair (4) also is the snag of net formula, and ball pivot (2) space 180 degree revolve arbitrarily Turn to. So just realized the purpose of this utility model. Thereby just can solve making at a distance of blackboard eraser The problem of the multifunction when using with dedusting.

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

Embodiment 1, in use, if the blackboard area is bigger, two net formula snag sheets (5) can be connected on the blackboard eraser hair (4), and Telescopic handle (3) is elongated, and enlarged the area that uses in then using greatly.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with the rigid plastics, utilize the basic equipment of injection moulding processing factory, take to assemble in batch to produce by batch, the demand with in the supply educational work so just can realize practical value of the present utility model and economic worth better.
