Description
The utility model relates to a kind of novel teacher's pointer blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance; Office appliance is write or the big class of drawing article, the assistant product group of writing or draw, the cleaning device technical group field of blackboard or slabstone.Classification number is B43L21/00.
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 novel teacher's pointer blackboard eraser, also once designed many outstanding technical schemes.As being declared by the model wisdom of the Decree of Patent Office of China in 1996, Granted publication number is CN2214304Y, and China Patent No. (ZL) is: No. 94241037.8 utility model title is the utility model patent of " blackboard eraser ", the technical scheme that is adopted.Cleaning device technical elements at blackboard or slabstone is a routine of great value invention, and it has solved the problem of blackboard eraser effectively.But still have some deficits, it also is difficult to solution can be used as blackboard eraser, can be used as the problem of teacher's pointer again.
The purpose of this utility model is to provide a kind of novel teacher's pointer blackboard eraser.Blackboard eraser can be used as to solve, the problem of teacher's pointer can be used as again.
The purpose of this utility model is achieved in that a kind of novel teacher's pointer blackboard eraser of this utility model.Mainly constitute by brush board, bristle, chute, teacher's pointer, end cap.Its brush board is the pane shape, uses wood material, through the machining manufacturing.Its bristle is the aciculiform shape, uses the bristle material, through the bonding processing and manufacturing.Its teacher's pointer is an elongate in shape, does not have wire material with radio, through the machining manufacturing.Its end cap is a cylindrical shape, uses wood material, through the machining manufacturing.Bristle adopts adhesive method to be connected the lower position of brush board, constitutes the Brush Shapes adhesive structure, and function has been the erasing blackboard effect.Teacher's pointer adopts fitting method to be installed in the interior location of chute, constitutes the elongate in shape fit structure, and function has been an indicative function.End cap adopts fitting method to be installed in the end position and the chute collar extension position of brush board, constitutes the cylindrical shape fit structure, and function has been to prevent that teacher's pointer from deviating to act on.So just realized the purpose of this utility model.
The utility model has been compared three advantages and improvement with the original blackboard or the cleaning device technology of slabstone;
The first, because the utility model has designed bristle, brush board in technical scheme, so can erase the board;
The second, because the utility model has designed teacher's pointer in technical scheme, so can be used as teacher's pointer;
The 3rd, because the utility model has designed end cap in technical scheme, pull out blackboard eraser so can prevent teacher's pointer; Blackboard eraser can be used as thereby just can more effectively solve, the problem of teacher's pointer can be used as again.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the agent structure synoptic diagram of a kind of novel teacher's pointer blackboard eraser of the utility model;
The numbering of parts explanation in the synoptic diagram: 1 brush board, 2 bristles, 3 chutes, 4 teacher's pointers, 5 end caps
In the optimum implementation of a kind of novel teacher's pointer blackboard eraser of the utility model, 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, a kind of novel teacher's pointer blackboard eraser of the utility model.Mainly constitute by brush board 1, bristle 2, chute 3, teacher's pointer 4, end cap 5.Bristle 2 adopts adhesive method to be connected the lower position of brush board 1, constitutes the Brush Shapes adhesive structure, and function has been the erasing blackboard effect.Teacher's pointer 4 adopts fitting method to be installed in the interior location of chute 3, constitutes the elongate in shape fit structure, and function has been an indicative function.End cap 5 adopts fitting methods to be installed in the end position and the chute 3 collar extension positions of brush board 1, constitutes the cylindrical shape fit structure, and function has been to prevent that teacher's pointer from deviating to act on.
Its dynamic structure: in force:
According to principle of confounding, its teacher's pointer 4 acts on chute by end cap 5, thus finishing indication, sliding of task.Its bristle 2 is used for brush board 1 by bonding, thereby finishes erasing the board of task.So just realized the purpose of this utility model.Blackboard eraser can be used as thereby just can solve, the problem of teacher's pointer can be used as again.
Below by using method, the utility model is done more detailed description:
A kind of novel teacher's pointer blackboard eraser of this utility model is work like this:
In use, when will erase the board, grasp the brush holder of blackboard eraser, utilize the rubbing action of bristle 2 on blackboard, both can reach the purpose that erases the board.
In use, when will use teacher's pointer,, make it outwards to move,, stop to draw, can work as teacher's pointer and use when moving to correct position along chute 3 with pulling teacher's pointer.
Realize that preferred plan of the present utility model is is material with wood, utilize the basic equipment of blackboard eraser factory, take single-piece to produce by batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
