The code mark of the utility model is B43L21/04, and the utility model is composed of a blackboard, a blackboard eraser, a magnet A, a magnet B, a piece of plastic cloth and nails. The utility model is characterized in that the cuboid magnet B is installed on the oblong block-shaped plastic cloth, and the utility model is a novel magnet blackboard eraser with practical value.
Description
The utility model relates to a kind of novel magnet blackboard eraser.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) classification, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The little technical group field of blackboard in the assistant product group of writing or draw, big group of reusable plate of writing or drawing or tablet.Be numbered B43L 21/04.
At present, the technology about the blackboard group in big group of the reusable plate of writing or drawing or the tablet existing and that once had was all done very fruitful effort to the demand of novel magnet blackboard eraser, also once designed many outstanding technical schemes.As being declared by Li Siyi of the Decree of Patent Office of China in 1996, Granted publication number is CN22411067Y, and China Patent No. (ZL) is: No. 95245058.5 utility model title is the utility model patent of " removing the dust blackboard eraser ", the technical scheme that is adopted.Blackboard group technical elements in big group of the reusable plate of writing or drawing or tablet is a routine of great value invention, and it has solved the problem that blackboard eraser removes dust effectively.But still have some deficits, it also is difficult to the excessive problem of dust when erasing the board that solves.
The purpose of this utility model is to provide a kind of novel magnet blackboard eraser.The excessive problem of dust when erasing the board with solution.
The purpose of this utility model is achieved in that a kind of novel magnet blackboard eraser of this utility model.Mainly constitute by blackboard, blackboard eraser, magnet A, magnet B, Polypropylence Sheet, nail.The Polypropylence Sheet of its pane shape adopts pin fixation to be installed on the blackboard of rectangular shape, forms the overall structure of a pane shape.The magnet B of its rectangular shape adopts laying method to be installed on the Polypropylence Sheet of pane shape.Form an OBL intermediate structure.The magnet A of its rectangular shape adopts fixing means to be installed on the blackboard eraser of rectangular shape.Form an OBL internal structure.Its blackboard eraser acts on magnet A by magnet B, thereby makes blackboard eraser satisfy the requirement that erases the board.Its Polypropylence Sheet acts on blackboard by nail, thereby makes Polypropylence Sheet finish the task of retaining ash.So just realized the purpose of this utility model.
The technology of the blackboard group in big group of the utility model and the original reusable plate of writing or drawing or the tablet has been compared three advantages and improvement;
The first, because the utility model has designed magnet in technical scheme, so solved the problem that can take blackboard eraser without hand;
The second, because the utility model has designed nail in technical scheme, can hang over top problem so solved Polypropylence Sheet;
The 3rd, because the utility model has designed Polypropylence Sheet in technical scheme, so solved the problem that can keep off dust.Thereby just can more effectively solve the excessive problem of dust when erasing the board.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the contour structures schematic diagram of a kind of novel magnet blackboard eraser of the utility model;
Fig. 2 is the broken section structural representation of a kind of novel magnet blackboard eraser of the utility model;
The numbering of parts explanation in the schematic diagram: 1 blackboard, 2 blackboard erasers, 3 magnet A, 4 magnet B, 5 Polypropylence Sheets, 6 nails
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of novel magnet blackboard eraser of the utility model.Mainly constitute by blackboard 1, blackboard eraser 2, magnet A 3, magnet B 4, Polypropylence Sheet 5, nail 6.Its major part nail 6, magnet A 3, magnet B 4 are by selecting for use on the market.Its blackboard 1 is a rectangular shape, makes material with hardwood, through the planing operation manufacturing.Its blackboard eraser 2 is rectangular shapes, makes material with hardwood, hair, through the bonding processing and manufacturing.Its Polypropylence Sheet 5 is oblong-shapeds, makes material with plastics, through the hot forming processing and manufacturing.The Polypropylence Sheet 5 of its pane shape adopts pin fixation to be installed on the blackboard 1 of rectangular shape, forms the overall structure of a pane shape.The magnet B 4 of its rectangular shape adopts laying method to be installed on the Polypropylence Sheet 5 of pane shape.Form an OBL intermediate structure.The magnet A 3 of its rectangular shape adopts fixing means to be installed on the blackboard eraser 2 of rectangular shape.Form an OBL internal structure.Its blackboard eraser 2 acts on magnet A 3 by magnet B 4, thereby makes blackboard eraser 2 satisfy the requirement that erases the board.Its Polypropylence Sheet 5 acts on blackboard 1 by nail 6, thereby makes Polypropylence Sheet 5 finish the task of retaining ash.So just realized the purpose of this utility model.Thereby just can solve the excessive problem of dust when erasing the board.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if erase the board 1, the Polypropylence Sheet 5 that is enclosed within two nails 6 of left end drawn back be set on two nails 6 of right-hand member, be put on the plastics with magnet B 4 then and hold the inside carry magnet A3 blackboard eraser 2, hold magnet B 4 and move around and to reach the purpose that erases the board, and can prevent dust.
Embodiment 2, in force, if blackboard 1 has been wiped, take away magnet B 4, then the cloth that is enclosed within on the right-hand member nail 6 unclamped, and blackboard 1 shown, conveniently to write.Thereby just can realize the purpose of this utility model.
Realize that preferred plan of the present utility model is is material with wood, plastics, hair, utilize the basic equipment of blackboard factory, take planing, hot forming, bonding to produce by batch, the demand with supply teaching circle so just can realize practical value of the present utility model and economic worth better.
