Dynamic device is rotated forward, electromagnetic driver reversion when pressing reversion button, and electromagnetic driver shuts down during release button;Described rubber
Spring is manufactured using rubber, creates the rubber bodies of tubular type, and the function of spring is realized using the deformation return function of rubber;
Described pillar creates and carries weight, the upper end of rotating roller and belt type blackboard and have and there is the support of rotation hole at middle part
Cylinder;
Described heel brace creates the horizontal cylinder or disking body of the weight of H load-bearing pillar, rotating roller and belt type blackboard;
Described rotating roller creates middle cylinder thick, small in ends, and part small in ends creates smooth rotation
Axle;
Described belt type blackboard creates flexible table using one or more material manufactures in plastics, nylon, rubber
The plate of the smooth coil type in face, then the plate of flexible coil type is surrounded into the ring of a long-tube, afterwards again by interface
The end at two ends be polished into after beveled mouth the blackboard that conveyer belt type is fixed and become with viscose glue;Described belt type blackboard is in manufacture
When warp and parallel can also be added in the plate of coil type to increase belt type blackboard the long ability of tension;
Wipe the part contacted with belt type blackboard outside described fixation to manufacture, create and can wipe using soft fiber or sponge
Fall the chalk trace eraser on blackboard;The part that the fixed outer back side wiped and two ends are fixed on pillar adopts hard material system
Make;When rotating roller drives belt type blackboard to rotate, inner press roll withstands on the inside one side of belt type blackboard and makes belt type blackboard convex
Go out, it is fixed outer wipe can be on erasing blackboard writing;
Chalk dust is set not fly everywhere to flutter in order to chalk dust is collected, additionally it is possible near below fixed outer wiping
Simultaneously it is fixed with disposable box behind pillar to collect chalk dust;Described disposable box is the rectangular box for having a bottom uncovered,
The two ends of disposable box are separately fixed on two pillars;
When using, directly write on blackboard or drawn with chalk;The not high people of height directly write in the middle and lower part of blackboard or
Draw, when writing blackboard bottom, press contact activate switch main story button connect solenoid or connect solenoid and
The circuit of electromagnet produces electromagnetic field, and the electromagnetic field that solenoid is produced is produced with electromagnet generation electromagnetic field or permanent magnet
Magnetic field is mutually exclusive and rotate forward solenoid, then drive inner press roll rotate forward;Drive when inner press roll is rotated forward
Belt type blackboard is rotated forward in rotating roller, and the main story that contact activate switch is unclamped after a certain distance is moved on belt type blackboard
Power supply circuits are disconnected after button makes electromagnetic driver shut down, and belt type blackboard stops movement, and afterwards, continuation is write on blackboard
Or draw;Solve the difficult problem that the not high people of height can not partly write above blackboard;
Tall people directly writes or draws on the top of blackboard, writes needs and bends over or squat down when can write picture, presses
The main story button of contact activate switch connects solenoid or connects the circuit generation electromagnetic field of solenoid and electromagnet, electricity
It is mutually exclusive and make solenoid that electromagnetic field and the electromagnet that magnetic coil is produced produces magnetic field that electromagnetic field or permanent magnet produce
Rotate forward, drive inner press roll to rotate forward then;Belt type blackboard forward direction in rotating roller is driven to turn when inner press roll is rotated forward
Dynamic, disconnection power supply circuits after the main story button that contact activate switch is unclamped after a certain distance are moved on belt type blackboard makes electromagnetism
Driver shuts down, and belt type blackboard stops movement, and afterwards, continuation is write or drawn on blackboard;Solve tall people
Can not partly be write the difficult problem for needing to bend over or squat down below blackboard, improve the comfortable of the picture that writes on blackboard
Property;
When the front of blackboard needs the calligraphy and painting on erasing blackboard after writing completely, main story button or the reversion of contact activate switch are pressed
Button connects solenoid or connects the circuit of solenoid and electromagnet and produces electromagnetic field, the electromagnetic field that solenoid is produced with
It is mutually exclusive and solenoid is rotated forward or is reversely rotated that electromagnet produces magnetic field that electromagnetic field or permanent magnet produce, after
And drive inner press roll to rotate forward or backwards;Drive belt type blackboard positive in rotating roller when inner press roll rotates forward or backwards or
Rotate backward, writing when belt type blackboard rotates forward or backwards in rotating roller, in the one side at the back side for rotating to blackboard
During the position wiped through fixed outer, inner press roll withstands in the inside of belt type blackboard and stand fast inside the back side of blackboard and allow fixation
The scraping sub-sections of outer wiping wipe the writing on the blackboard back side off, and belt type blackboard can all be fixed outer wiping through the fixed outer part wiped
Except clean;After blackboard is wiped clean, disconnecting power supply circuits after the main story button or reversion button that unclamp contact activate switch makes electricity
Magnetic driven device shuts down, and completes the auto-erasing of the writing on blackboard;When outer erasing the board is fixed, by the way of striking off
Wipe the writing on blackboard off, when the writing on blackboard is struck off, the outer erasure of fixation does not have air flow to produce wind, chalk
Ash sinks and drops in disposable box naturally, makes to be flutterred without the winged of chalk dust in classroom.
2. Assembled rotary according to claim 1 wipes word blackboard, it is characterised in that:In order that fixed outer wiping is erasing the board
When, wipes totally, and the one side for erasing the board wiped outside described fixation can also create blade insert using elastomeric material.
