Description
(1) technical field:
The utility model relates to a kind of novel chalk to be wiped, and divides by International Patent Classification (IPC) (IPC) to belong to operation Department of Transportation, printing branch, write or the plotter people, 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.
(2) background technology:
At present, the demand that the technology about the cleaning device of blackboard or slabstone existing and that once had is wiped novel chalk was all done very fruitful effort, also once designed many outstanding technical schemes.As being declared by Ou Xiang of the Decree of Patent Office of China in 1996, Granted publication number is CN2235904Y, and China Patent No. (ZL) is: No. 95208816.9 utility model title is the utility model patent of " blackboard eraser gathers dust ", 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 technical problem that blackboard eraser gathers dust effectively.But still have some deficits, it also is difficult to solve the laborsaving timesaving that erases the board and draws the art problem.
(3) summary of the invention:
The purpose of this utility model is to provide a kind of novel chalk to wipe.With the solution laborsaving timesaving technical problem that erases the board.
The technical scheme that the technical problems to be solved in the utility model adopted be achieved in that a kind of novel chalk of this utility model wipe mainly by: framework, chute A, blackboard, chute B, ball A, brush board, ball B, iron wire, bristle constitute.Its framework, chute A, chute B, brush board are oblong-shapeds, use wood material, through the planing operation manufacturing.Its blackboard is an oblong-shaped, uses the frosted glass material, through the thermoforming processing and manufacturing.Its bristle is the aciculiform shape, uses the bristle material, through the bonding processing and manufacturing.
In shape, textural, a kind of novel chalk of the present utility model is wiped the essential features that has with immediate prior art and is: the blackboard bonding is installed in the medium position of framework, constitutes the oblong-shaped fixed structure, and function has been the effect of writing.Brush board is connected the upper-lower position of ball A and ball B by iron wire, constitutes the oblong-shaped syndeton, and function has been the effect of controlling.The bristle bonding is installed in the right positions of brush board, constitutes aciculiform shape adhesive structure, and function has been a scrubbing action.Ball A cooperates the interior location that is installed in chute A, constitutes the ball shape fit structure, and function has been a rolling action.In shape, textural, the novel umbrella formula Air inflation rain cape of the present utility model technical characterictic different with immediate prior art is: ball B cooperates the interior location that is installed in chute B, constitutes the ball shape fit structure, and function has been laborsaving effect during Sliding blackboard is wiped.Chute A and chute B are installed in the position, top and bottom of framework respectively, constitute overall structure, and function has been the effect of advance ball.So just realized the erase the board purpose of laborsaving timesaving technical problem of solution that a kind of novel chalk of the present utility model is wiped.
The beneficial effect that a kind of novel chalk of utility model is wiped is that the utility model is that the solution laborsaving technical scheme that technical problem adopted of saving time that erases the board has been compared two place's advantage and improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had:
The first, owing to designed ball in the technical scheme that a kind of novel chalk of the present utility model is wiped, so labour-saving technical problem in the wiping of easier solution Sliding blackboard.
The second, owing to designed chute in the technical scheme that a kind of novel chalk of the present utility model is wiped, so the technical problem of easier solution advance ball.

The label declaration of parts in the schematic diagram:
1 framework, 2 chute A, 3 blackboards, 4 chute B, 5 ball A
6 brush boards, 7 ball B, 8 iron wires, 9 bristles
(5) specific embodiment:
Below in conjunction with accompanying drawing, the optimal way that a kind of novel chalk of the present utility model is wiped to realizing solving the technical scheme that the laborsaving timesaving technical problem that erases the board taked is described further:
Its static structure: please join accompanying drawing: as shown in the figure, a kind of novel chalk of the present utility model is wiped and mainly is made of framework 1, chute A2, blackboard 3, chute B4, ball A5, brush board 6, ball B7, iron wire 8, bristle 9.Its framework 1, chute A2 chute B4, brush board 6 are oblong-shapeds, use wood material, through the planing operation manufacturing.Its blackboard 3 is oblong-shapeds, uses the frosted glass material, through the thermoforming processing and manufacturing.Its bristle 9 is aciculiform shapes, uses the bristle material, through the bonding processing and manufacturing.
In shape, textural, a kind of novel chalk of the present utility model is wiped the essential features that has with immediate prior art and is: blackboard 3 bondings are installed in the medium position of framework 1, constitute the oblong-shaped fixed structure, and function has been the effect of writing.Brush board 6 is connected the upper-lower position of ball A5 and ball B7 by iron wire 8, constitutes the oblong-shaped syndeton, and function has been the effect of controlling.Bristle 9 bondings are installed in the right positions of brush board 6, constitute aciculiform shape adhesive structure, and function has been a scrubbing action.Ball A5 cooperates the interior location that is installed in chute A2, constitutes the ball shape fit structure, and function has been a rolling action.In shape, textural, a kind of novel chalk of the present utility model is wiped the technical characterictic different with immediate prior art and is: ball B7 cooperates the interior location that is installed in chute B4, constitutes the ball shape fit structure, and function has been a rolling action.Chute A2 and chute B4 are installed in the position, top and bottom of framework 1 respectively, constitute overall structure, and function has been the effect of advance ball.
Its dynamic structure: in the optimal way of implementing, in use, when need erase the board, with holding letter brush board 6, firmly make it to slide to the other end from an end, because ball A5 and ball B7 are rolling, the brush board 6 that is through on the iron wire 8 also can slide thereupon, and the bristle 9 that contacts with blackboard 3 can reach and wipe the word purpose like this.
Its dynamic structure: in the optimal way of implementing, in use, when word has been wiped, can the same using method the brush board 6 mobile blackboard leftmost side or the rightmost sides, write to prevent obstruction.So just realized solution tradition that a kind of novel chalk of the present utility model the is wiped laborsaving timesaving technical problem purpose that erases the board.
Realize that preferred plan of the present utility model is is material with frosted glass, wood, utilize the basic equipment of blackboard eraser factory, take assembling to produce by batch,, so just can realize practical value and economic worth that a kind of novel chalk of the present utility model is wiped better with the demand of supply educational circles.
