Abstract
The utility model relates to a novel blackboard, which comprises a metal bar, a wooden frame, a front glass plate, a handle, a back baffle, a magnetic particle cavity and a back glass plate. As the magnetic particle cavity is designed in the technical proposal of the utility model, the utility model can write and the metal bar is designed in the technical proposal, the direct erasing can be realized, and the utility model is characterized in that an interlayer of the magnetic particle is arranged at the back position of the front glass plate and the utility model is the novel blackboard with practical values.
Description
(1) technical field:
The utility model relates to a kind of new type blackboard.Belong to operation Department of Transportation by International Patent Classification (IPC) (IPC) division, printing branch is write or drawing appliance, and the big class of office appliance is write or the drawing appliance group, big group of nib, writing-point, the little technical group field at wide tip.
(2) background technology:
At present, existing and once had about big group of nib, writing-point, the technology of the group at wide tip was all done very fruitful effort to the demand of new type blackboard, also once designed many outstanding technical schemes.As being declared by Liu Hongzhong of the Decree of Patent Office of China in 1996, Granted publication number is CN216929Y, and China Patent No. (ZL) is: No. 95202331.8 utility model title is the utility model patent of " sliding door self-erasing type blackboard ", the technical scheme that is adopted.Big group of nib, writing-point, group's technical elements at wide tip is a routine of great value invention, and it has solved the problem of sliding door self-erasing type blackboard effectively.But still have some deficits, it also be difficult to solve blackboard that present teacher uses in the class, and teacher has write the later problem that must wipe word of word.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of new type blackboard.To solve blackboard that present teacher uses in the class, teacher has write the problem that must wipe word after the word.
The purpose of this utility model is achieved in that a kind of new type blackboard of this utility model.Mainly constitute by metal bar, wooden frame, front glass panel, handle, backboard, magnetic chamber, back glass plate.Its front glass panel, back glass plate are by selecting for use on the market.Its metal bar is the clavate shape, uses metal material, through the turning processing and manufacturing.Its wooden frame side of being strip is used wood material, through the planing operation manufacturing.Its handle is a circle petioliform shape, uses wood material, through the planing operation manufacturing.Its backboard is a flat shape, uses wood material, through the planing operation manufacturing.Its magnetic chamber is a cavity shape, uses magnetic powder material, through the planing operation manufacturing.Front glass panel adopts the draw-in groove method to be installed in the middle position of wooden frame, constitutes fixed structure, and function has been a fixation.Back glass plate adopts the draw-in groove method to be installed in the middle position of wooden frame, constitutes fixed structure, and function has been a fixation.Handle 4 adopts the nail method to be installed in the lower position of metal bar, constitutes fixed structure, and function has been the convenient effect of push-and-pull.Backboard adopts the draw-in groove method to be installed in the central rear position of wooden frame, constitutes fixed structure, and function has been the rear portion baffle effect.The magnetic chamber adopts sandwich method to be installed in the rear positions of front glass panel, constitutes fixed structure, and function has been the effect of writing.The magnetic chamber adopts sandwich method to be installed in the forward position of lower glass plate, constitutes fixed structure, and function has been the effect of writing.Metal bar adopts the chute method to be installed in the rear positions in magnetic chamber, constitutes movable structure, and function has been to wipe the word effect.So just realized the purpose of this utility model.
The advantage of utility model: big group of the utility model and original nib, writing-point, group's technology at wide tip has been compared two advantages and improvement;
The first, because the utility model has designed the magnetic chamber in technical scheme, so can write;
The second, because the utility model has designed metal bar in technical scheme, so can directly wipe; Thereby just can more effectively solve blackboard that present teacher uses in the class, teacher has write the problem that must wipe word after the word.
(4) description of drawings:
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is the structural representation of facing of a kind of new type blackboard of the present utility model;
Fig. 2 is the side-looking structural representation of a kind of new type blackboard of the present utility model;
Fig. 3 is the cross-sectional view in the square magnetic chamber of a kind of new type blackboard of the present utility model;
The numbering of parts explanation in the schematic diagram: 1 metal bar, 2 wooden frames, 3 front glass panel, 4 handles, 5 backboards, 6 magnetic chambeies, 7 back glass plates
(5) specific embodiment:
In the optimum implementation of a kind of new type blackboard of the present 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: see also Fig. 1: as shown in the figure, a kind of new type blackboard of the present utility model.Mainly constitute by metal bar 1, wooden frame 2, front glass panel 3, handle 4, backboard 5, magnetic chamber 6, back glass plate 7.Front glass panel 3 adopts the draw-in groove method to be installed in the middle position of wooden frame 2, constitutes fixed structure, and function has been a fixation.Back glass plate 7 adopts the draw-in groove method to be installed in the middle position of wooden frame 2, constitutes fixed structure, and function has been a fixation.Handle 4 adopts the nail method to be installed in the lower position of metal bar 1, constitutes fixed structure, and function has been the convenient effect of push-and-pull.Backboard 5 adopts the draw-in groove method to be installed in the central rear position of wooden frame 2, constitutes fixed structure, and function has been the rear portion baffle effect.Magnetic chamber 6 adopts sandwich method to be installed in the rear positions of front glass panel 3, constitutes fixed structure, and function has been the effect of writing.Magnetic chamber 6 adopts sandwich method to be installed in the forward position of lower glass plate 7, constitutes fixed structure, and function has been the effect of writing.Metal bar 1 adopts the chute method to be installed in the rear positions in magnetic chamber 6, constitutes movable structure, and function has been to wipe the word effect.
Its dynamic structure: in force:
According to magnetic principles, its front glass panel 3 acts on magnetic chamber 6 by back glass plate 7, thereby finishes the task of writing.
According to magnetic principles, its metal bar 1 acts on magnetic chamber 6, thereby finishes the task of wiping word.So just realized the purpose of this utility model.Thereby just can solve blackboard that present teacher uses in the class, teacher has write the problem that must wipe word after the word.
Below by using method, the utility model is done more detailed description:
A kind of new type blackboard of this utility model is work like this:
In use, when writing, according to magnetic principles, its front glass panel 3 acts on magnetic chamber 6 by back glass plate 7, thereby finishes the task of writing.
In use, when wiping word, according to magnetic principles, its metal bar 1 acts on magnetic chamber 6, thereby finishes the task of wiping word.
Realize that preferred plan of the present utility model is is material with wood, utilize the basic equipment of wooden tool factory, produce by batch in taking, the demand with supply stationery circle so just can realize practical value of the present utility model and economic worth better.
