Description
Technical field
The present invention relates to a kind of realia, especially a kind of emperorship that erases the board easy to erase the board.
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 emperorship that erases the board easy to erase the board.
The content of the invention
Erase the board emperorship it is an object of the invention to provide one kind, can quickly wipe clean blackboard.
The present invention is achieved through the following technical solutions：The present invention erases the board emperorship, mainly by guide groove, blackboard, motor board
Wipe, formed along bracing wire, side line groove, reel, commutator, motor, switch, inverse bracing wire, fixed pulley, wire and plug, its feature
It is：One guide groove is respectively installed on the both sides up and down of blackboard, guide groove is embedded with an electric eraser, in the right and left of blackboard
Respectively one side line groove of installation.Electronic wiping board mainly includes a root long bar hardboard, is equipped with soft cotton rub on the inside of strip hardboard, two respectively connects
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 peace
A uplink wheel is filled, is pressed in above spring, the lower section of guide cylinder is equipped with a downlink wheel.The cross section of guide groove be "" shape
, it is made of overhead gage, upper cell wall, groove inner cavity, rear cell wall, lower baffle plate and lower cell wall, 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 electric eraser
Blackboard.Guide groove and side line groove form a rectangle, and a fixed pulley is respectively provided with four chamfered grooves, be equipped with the side line groove on one side around
Line wheel, commutator, motor and switch, are connected with directive wheel along bracing wire and inverse bracing wire, determine cunning along bracing wire and inverse be drawstring through
Wheel is connected on reel, and motor is connected with wire and plug.During work, by lower switch, motor is powered, and drives reel suitable
Turn or reverse, when reel is clockwise, inverse bracing wire lengthens, along guy winding on reel, so as to pull electric eraser to move right
It is dynamic, when reel reverses, then conversely, electronic wiping board is moved to the left.When electronic wiping board moves on to side line trough rim, stop one by side line groove
Under, commutator is had an effect, automatic reverse, and electronic wiping board starts to move back, and can quickly wipe the writing on blackboard.Wipe black
After plate, then switch is clicked, power-off is stopped.Usually, electric eraser can rest in side line trough rim, do not interfere with and write.
The present invention erases the board emperorship, simple in structure, easily makes, of low cost, economical and practical, popularization easy to spread.
