Abstract
The utility model relates to a dust proof blackboard eraser, and belongs to the technical field of the cleaning device of the blackboard or the stone plate, the writing supplies or the drawing supplies, the writing supplies or the drawing auxiliary supplies sub subclass, the writing appliance or the drawing appliance or the office appliance class, the printing subpart, and the operation and the transportation part according to the division of the international patent classification (IPC). The utility model aims at solving the problem that chalk dust is heavy when a blackboard is cleaned, and the utility model is characterized in that the utility model mainly comprises a main board, a handle, eraser hairs, dust proof plates, and screws. The eraser hairs and the screws are installed at the bottom part of the main board to form a rectangle integrated structure and perform the function of dust removal. The dust proof plates are adhered and installed on the both sides of the main board to form a rectangle integrated structure and perform the function of ash removal. The utility model has the optimal mode for realizing the proposal that the lumber, the colloidal matter and the hairs are performed as material, basic equipment in a wood work shaping plastic factory is used, the bulk production is adopted to satisfy the demands of the living, therefore the use value and the economic value of the dust proof blackboard eraser is realized.
Description
(1) technical field:
The utility model relates to dust-proof blackboard eraser, divides by International Patent Classification (IPC) (IPC) to belong to operation, Department of Transportation, printing branch, 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.
(2) background technology:
At present, the technology about the cleaning device group of blackboard or slabstone existing and that once had was all done very fruitful effort to the demand of dust-proof blackboard eraser, also once designed many outstanding technical schemes.As being declared by Gao Qisong of the Decree of Patent Office of China, Granted publication is CN2190035Y, and China Patent No. (ZL) is: No. 94210981.3 utility model patent title is the utility model patent of " blackboard eraser ", the technical scheme that is adopted.Technical elements in the cleaning device group of blackboard or slabstone is a routine of great value invention, and it has solved the technical problem of blackboard eraser effectively.But still have some deficits, it also is difficult to solve the big technical problem of chalk dust when erasing the board.
(3) summary of the invention:
The big technical problem of chalk dust when the purpose of this utility model is to provide a kind of dust-proof blackboard eraser to erase the board with solution.
The dust-proof blackboard eraser that the technical scheme that the technical problems to be solved in the utility model adopted is achieved in that this utility model mainly by: mainboard, shake hands, snag, dust excluding plate, screw constitute.Its major part screw is selected for use by market.Its mainboard is a cube shaped, uses wood materials, through art worker processing and manufacturing.Shaking hands of it is the lower frame shape, uses wood materials, through carpenter's processing and manufacturing.Its snag is a rectangular shape, with the hair material, adds manufacturing through shaping.Its dust excluding plate is the flexible glue shape, uses colloidal materials, through moulding processing and manufacturing.
In shape, textural, the total essential features of the utility model dust-proof blackboard eraser and immediate prior art is: the screw of shaking hands is installed in the last medium position of mainboard, constitutes lower frame shape shape integrative-structure, and function has been the effect of handle.In shape, textural, the utility model dust-proof blackboard eraser technical characterictic different with immediate prior art is: the snag screw is installed in the bottom position of mainboard, constitutes the rectangular shape integrative-structure, and function has been the ash disposal effect.Dust excluding plate is pasted two side positions that are installed in mainboard, constitutes the rectangular shape integrative-structure, and function has been the anti-gray effect.The big purpose of chalk dust when so just having realized the erasing the board of the utility model dust-proof blackboard eraser:
The beneficial effect of the dust-proof blackboard eraser of utility model is that the utility model is that the technical scheme that technical problem adopted of solution chalk dust general idea when erasing the board has been compared a place's advantage and an improvement with existing with the technology about the cleaning device group of blackboard or slabstone that once had:
The first, owing to designed anti-hawk in the technical scheme of the utility model dust-proof blackboard eraser, so can prevent that dust from scattering.
(4) description of drawings:
Accompanying drawing provides dust-proof blackboard eraser of the present utility model and structural representation:
Fig. 1: the main TV structure schematic diagram that is the utility model dust-proof blackboard eraser:
Fig. 2: the structural representation of looking up that is the utility model dust-proof blackboard eraser:
The label declaration of parts in the schematic diagram: 1 mainboard 2,3 snags, 4 dust excluding plates, 5 screws of shaking hands
(5) specific embodiment:
Below in conjunction with accompanying drawing, be that the optimal way that realization solves the technical scheme that the big technical problem of chalk dust is taked when erasing the board is described further to the utility model dust-proof blackboard eraser:
Its static structure: see also Fig. 1: as shown in the figure, the utility model dust-proof blackboard eraser mainly by mainboard 1, shake hands 2, snag 3, dust excluding plate 4, screw 5 constitute.Its mainboard 1 is a cube shaped, uses wood materials, through carpenter's processing and manufacturing.Shaking hands of it 2 is lower frame shapes, uses wood materials, through carpenter's processing and manufacturing.Its snag 3 is rectangular shape, with the hair material, through the shaping processing and manufacturing.Its dust excluding plate 4 is flexible glue shapes, uses colloidal materials, through moulding processing and manufacturing.
In shape, textural, the total essential features of the utility model dust-proof blackboard eraser and immediate prior art is: 2 screws of shaking hands are installed in the last medium position of mainboard 1, constitute lower frame shape shape integrative-structure, and function has been the effect of handle.In shape, textural, the utility model dust-proof blackboard eraser technical characterictic different with immediate prior art is: snag 3 screws are installed in the bottom position of mainboard 1, constitute the rectangular shape integrative-structure, and function has been the ash disposal effect.Dust excluding plate 4 is pasted two side positions that are installed in mainboard 1, constitutes the rectangular shape integrative-structure, and function has been the anti-gray effect.
Its dynamic structure: in the optimal way of implementing, in use,, all be that according to mechanics principle, its mainboard 1 acts on dust by dust excluding plate 4 when wiping ash, thereby finish the task of retaining ash when in the class.The big purpose of chalk dust when so just having realized the erasing the board of the utility model dust-proof blackboard eraser.
Realize that preferred plan of the present utility model is with wooden, colloid, Mao Zhiwei material, utilize carpenter, shaping, mould the basic equipment of factory, take to produce by batch in batches, with the demand of supply daily life, so just can realize the practical value and the economic worth of the utility model dust-proof blackboard eraser better.
