Description
The utility model relates to a kind of novel blackboard eraser.(IPC) belongs to operation Department of Transportation by International Patent Classification (IPC), and printing branch is write or drawing appliance, and 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.Be numbered B43L 21/00.
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 blackboard eraser, also once designed many outstanding technical schemes.As declaring of the Decree of Patent Office of China on the 3rd October in 1996 by Yang Bing, Granted publication number is CN2266521Y, China Patent No. (ZL) is: No. 96238614.6 utility model title is the utility model patent of " two wiping formula blackboard ", the technical scheme that is adopted.Cleaning device technical elements at blackboard or slabstone is a routine of great value invention, and the last bottom that it has solved blackboard effectively is provided with groove, in the last following embedded groove of blackboard eraser, and the problem that moves along groove.But still have some deficits, it also is difficult to solve do not make chalk dust fly away aerial problem when erasing the board.
The purpose of this utility model is to provide a kind of novel blackboard eraser.Do not make chalk dust fly away aerial problem when erasing the board with solution.
The purpose of this utility model is achieved in that a kind of novel blackboard eraser of this utility model.Mainly constitute by block body, holder, felt, connector, chalk dust bag.Its major part felt, holder are by selecting for use on the market.Its block body is a rectangular shape, makes material with rubber, through the thermoforming processing and manufacturing.Its connector is the coupler body shape, makes material with plastics, through the thermoforming processing and manufacturing.Its chalk dust bag is a rectangular shape, makes material with plastics, through the thermoforming processing and manufacturing.The felt of its rectangular shape adopts method of attaching to be installed on the holder of rectangular shape, form the sticking structure of a rectangular shape, the block body of its rectangular shape adopts adhesive method to be installed in around the holder of rectangular shape, form the adhesive structure of a rectangular shape, the connector of its hook-like shape adopts the screw method of attachment to be installed on the holder of rectangular shape, form a screw syndeton that has the rectangular shape of coupler body, the chalk dust bag of its rectangular shape adopts the screw attachment method to be installed on the connector of hook-like shape, form the screw attachment structure of a serpentine shape, its block body acts on felt by holder, thereby block body is satisfied prevent that chalk dust from flying away aerial requirement everywhere, its holder acts on the chalk dust bag by connector, thereby makes the packed task of going into chalk dust of chalk dust.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 block body in technical scheme, can prevent that chalk dust from flying away aerial problem so solved;
The second, because the utility model has designed connector in technical scheme, so solved the problem that connects the chalk dust bag;
The 3rd, because the utility model has designed the chalk dust bag in technical scheme, so solved the problem of the chalk dust of packing into; Do not make chalk dust fly away aerial problem when erasing the board thereby just can more effectively solve.
Accompanying drawing provides structural representation of the present utility model:
Fig. 1 is that the A of a kind of novel blackboard eraser of the utility model is to the sectional structure schematic diagram;
Fig. 2 is the main TV structure schematic diagram of a kind of novel blackboard eraser of the utility model;
The numbering of parts explanation in the schematic diagram: 1 block body, 2 holders, 3 felts, 4 connectors, 5 chalk dust bags
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, a kind of novel blackboard eraser of the utility model. Mainly by block body 1, holder 2, Felt 3, connector 4, chalk dust bag 5 consist of. Its major part felt 3, holder 2 by selecting on the market. Its block body 1 is rectangular shape, makes material with rubber, through overheated one-tenth The type processing and manufacturing. Its connector is the coupler body shape, makes material with plastics, through thermoforming processing system Make. Its chalk dust bag 5 is rectangular shapes, makes material with plastics, through thermoforming processing system Make. The felt 3 of its rectangular shape adopts method of attaching to be installed in the holder of rectangular shape On 2, form the sticking structure of a rectangular shape, the block body 1 of its rectangular shape adopts Adhesive method is installed in around the holder 2 of rectangular shape, forms the sticking of a rectangular shape Junction structure, the connector 4 of its hook-like shape adopts screw connection method to be installed in rectangular shape Holder 2 on, form the screw connecting structure with the rectangular shape of coupler body, it The chalk dust bag 5 of rectangular shape adopts the screw attachment method to be installed in the connector 4 of hook-like shape On, the screw attachment structure of a serpentine shape of formation, its block body 1 is by holder 2 Act on felt 3, prevent that chalk dust from flying away aerial requirement everywhere thereby block body 1 is satisfied, Its holder 2 acts on chalk dust bag 5 by connector 4, thereby makes chalk dust bag 5 dresses Enter the task of chalk dust. So just realized the purpose of this utility model. Black thereby just can solve Do not make chalk dust fly away aerial problem during plate.
Below by embodiment, the utility model is done more detailed description:
Embodiment 1, in force, if erase the board, hand is taken fixed body 2, make chalk dust bag 5 below, just can erase the board, because block body 1 has surrounded fixed body 2 and felt 3, so can disorderly not waft everywhere after chalk dust is wiped by felt 3, and be enclosed in the block body 1 chalk dust that while chalk dust bag 5 can be enclosed in the block body 1.
Realize that preferred plan of the present utility model is is material with rubber, plastics, utilize the basic equipment of blackboard eraser processing factory, take thermoforming to produce in batch, the demand with supply educational circles so just can realize practical value of the present utility model and economic worth better.
