Description

A kind of new no-dust blackboard eraser

The utility model relates to a kind of new no-dust 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, blackboard technical group field.Be numbered B43L1/04.

At present, the technology about blackboard existing and that once had was all done very fruitful effort to the demand of new no-dust blackboard eraser, also once designed many outstanding technical schemes.As the Decree of Patent Office of China in 1996 generation advances to declare by rising, Granted publication number is CN2223693Y, China Patent No. (ZL) is: No. 95233376.7 utility model title is the utility model patent of " a kind of controlled blackboard of displaying ", the technical scheme that is adopted.Be a routine of great value invention aspect blackboard, it has solved the problem of the controlled demonstration of blackboard effectively.But still have some deficits, it also is difficult to solve the problem that does not play chalk dust when erasing the board.

The purpose of this utility model is to provide a kind of new no-dust blackboard eraser.Do not play the problem of chalk dust when erasing the board with solution.

The purpose of this utility model is achieved in that a kind of new no-dust blackboard eraser of this utility model.Mainly constitute by dust catcher, box body, switch, pulley, big blackboard eraser, blackboard eraser, lower guideway, blackboard, upper rail, blackboard frame.Its major part blackboard eraser, switch, dust catcher, pulley are by selecting for use on the market.Its box body, big blackboard eraser are rectangular shapes, make material with plastics, through the hot forming processing and manufacturing.Its upper rail and lower guideway are rectangular shapes, make material with aluminium alloy, touch processing and manufacturing through overvoltage.The dust catcher of its rectangular shape adopts the screw attachment method to be installed in the box body of rectangular shape.Form the screw attachment structure of a rectangular shape.The big blackboard eraser of its rectangular shape adopts the screw attachment method to be installed on the box body of rectangular shape.Form the screw attachment structure of a rectangular shape.The big blackboard eraser of its rectangular shape adopts the pulley coupling method to be installed on the upper rail and lower guideway of rectangular shape.Form the pulley draw bail of " I " word shape.The upper rail of its rectangular shape and lower guideway adopt the screw attachment method to be installed on the blackboard frame of rectangular shape.Form the screw attachment structure of a rectangular shape.Its big blackboard eraser acts on dust catcher by box body.Thereby make dust catcher satisfy the requirement that can suck chalk dust.Its upper rail by pulley action in big blackboard eraser.Thereby big blackboard eraser being finished erase the board makes chalk dust fall into the task of box body.So just realized the purpose of this utility model.

The technology of the utility model and original blackboard has been compared three advantages and improvement;

The first, because the utility model has designed dust catcher in technical scheme, so solved the problem that can suck chalk dust;

The second, because the utility model has designed big blackboard eraser in technical scheme, make chalk dust fall into the interior problem of box body so solved to erase the board;

The 3rd, because the utility model has designed pulley in technical scheme, so solved the problem that big blackboard eraser is slided between upper rail and lower guideway.Thereby just can more effectively solve the problem that does not play chalk dust when erasing the board.

Accompanying drawing provides structural representation of the present utility model:

Fig. 1 is the structural representation of a kind of new no-dust blackboard eraser of the utility model;

The numbering of parts explanation in the schematic diagram: 1 dust catcher, 2 box bodys, 3 switches, 4 pulleys, 5 big blackboard eraser 6 blackboard erasers 7 lower guideways 8 blackboards 9 upper rails 10 blackboard frames

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in the figure, a kind of dust-free blackboard eraser of the utility model. Mainly by dust catcher 1, box Body 2, switch 3, pulley 4, big blackboard eraser 5, blackboard eraser 6, lower guideway 7, blackboard 8, upper rail 9, blackboard frame 10 consist of. Its major part blackboard eraser 6, switch 3, Dust catcher 1, pulley 4 are by selecting on the market. Its box body 2, big blackboard eraser 5 are cuboids Shape is made material with plastics, through the hot forming processing and manufacturing. Its upper rail 9 and lower guideway 7 Be rectangular shape, make material with aluminium alloy, touch processing and manufacturing through overvoltage. Its rectangular shape Dust catcher 1 adopts the screw attachment method to be installed in the box body 2 of rectangular shape. Form one long The screw attachment structure of side's shape. The big blackboard eraser 5 of its rectangular shape adopts screw attachment Method is installed on the box body 2 of rectangular shape. Form the screw attachment knot of a rectangular shape Structure. The big blackboard eraser 5 of its rectangular shape adopts the pulley coupling method to be installed in rectangular shape Upper rail 9 and lower guideway 7 on. Form the pulley draw bail of " I " word shape. It The upper rail 9 of rectangular shape and lower guideway 7 adopt the screw attachment methods to be installed in cuboid On the blackboard frame 10 of shape. Form the screw attachment structure of a rectangular shape. Its big blackboard eraser 5 act on dust catcher 1 by box body 2. Thereby dust catcher 1 is satisfied to suck chalk The requirement of ash. Its upper rail 9 acts on big blackboard eraser 5 by pulley 4. Thereby make big black Blackboard eraser 5 is finished to erase the board and is made chalk dust fall into the task of box body 2. So just realized this practicality Novel purpose. Thereby just can solve the problem that does not play chalk dust when erasing the board.

Below by embodiment, the utility model is done more detailed description:

Embodiment 1, in force, erase the board if want, can open switch 3, dust catcher 1 is started working, big blackboard eraser 5 is slided between upper rail 7 and upper rail 9, big blackboard eraser 5 is wiped clean blackboard 8 when sliding, dust catcher 1 sucks the chalk dust of wiping in the box body 2 along big blackboard eraser 5 simultaneously, prevents that chalk dust from flying away in air.

Embodiment 2, and in force, if when erasing the board, big blackboard eraser 5 some place are not wiped clean, and can use the blackboard eraser 6 that is placed on the lower guideway 7, and hand-held blackboard eraser 6 just can have been wiped clean the place of needs.Thereby just can realize the purpose of this utility model.

Realize that preferred plan of the present utility model is is material with plastics, aluminium alloy, utilize the basic equipment of blackboard factory, take hot forming, pressing mold to produce by batch, the demand with supply study article circle so just can realize practical value of the present utility model and economic worth better.
