Description
Technical field
It is especially a kind of easy to the blackboard eraser of the quick wipe to erase the board the present invention relates to a kind of realia.
Background technology
Existing middle and primary schools' teaching blackboard used, is nearly all in addition to match somebody with somebody a slight blackboard eraser, erase the board time-consuming expense
Power, it is difficult to wipe clean, and some students everywhere leave about blackboard eraser, make chalk dust be everywhere, and it is very unhygienic, therefore urgently
Need a kind of easy to the blackboard eraser of the quick wipe to erase the board.
The content of the invention
It is an object of the invention to provide a kind of blackboard eraser of quick wipe, blackboard can be quickly wiped clean.
The present invention is achieved through the following technical solutions：The blackboard eraser of quick wipe of the present invention, mainly by guide groove, strip plate
Wiping, directive wheel, baffle and blackboard are formed, it is characterized in that：On the both sides up and down of blackboard, respectively one guide groove of installation, guide groove embed
There is a root long bar blackboard eraser, a piece baffle is respectively installed in the right and left of blackboard, strip blackboard eraser is not slided into outside blackboard.Strip
Wiping board mainly includes a root long bar hardboard, is equipped with a handle among the outside of strip hardboard, inner side is equipped with soft cotton rub, and two is each
Connect a directive wheel.The main body of directive wheel is a circular guide cylinder, and a spring is equipped with guide cylinder, is oriented to nozzle side
One uplink wheel is installed, is pressed in above spring, the lower section of guide cylinder is equipped with a downlink wheel.Guide groove by overhead gage, upper cell wall,
Groove inner cavity, rear cell wall, lower baffle plate and lower cell wall are formed, intracavity section be "" shape.By the inner cavity of directive wheel insertion guide groove
In, uplink wheel is close to the upper cell wall of guide groove, and downlink wheel is close to lower cell wall, and the elastic force of spring is close to the soft cotton rub of strip blackboard eraser
Blackboard.Hold handle and move left and right strip blackboard eraser, it is possible to quickly wipe the writing on blackboard；Usually, strip plate
Wiping can lean against baffle side, do not interfere with and write.
The blackboard eraser of quick wipe of the present invention, it is simple in structure, easily make, it is of low cost, it is economical and practical, it is easy to spread general
And.
