Preferably, sliding block is welded in the first board of education, and sliding block and sliding slot are corresponding, and the first board of education is in rise and fall
The stability of the first board of education is balanced in journey by the active force of sliding block and sliding slot.
Preferably, the bottom of sliding slot is slightly above blackboard bottom, and the length of sliding slot is slightly larger than twice of first board of education.
Preferably, support base includes hound, diagonal brace connecting plate and pull rod, and hound passes through screw with diagonal brace connecting plate
Connection.
Preferably, motor is placed on diagonal brace connecting plate, saves space, while one can be separately provided on inclined plate
The compartment for placing motor, can play the effect of sound insulation.
Preferably, motor is equipped with turntable, chain link turntable is rotated, in order to enable the first board of education occurs in lifting process
It tilts, power of motor should be not more than the maximum power that the first board of education can bear.
Preferably, second gear of the rotation axis on the top of the first board of education, rotating wheel and the tooth in the first board of education
It is mutually ratcheting at the top of item so that when start-up operation, the first board of education to be enabled to rise to maximum value.
The present invention operation principle be：Motor drives first gear, first gear to drive rotation axis, rotation by swivel-chain
Axis drives the lifting of the first board of education, the first board of education two by the ratcheting rotation of second gear and the first board of education upper rack
Side slide interacts with the sliding slot on supporting rod, stablizes the first board of education, when the first board of education rises to certain altitude, the
Two boards of education reveal, and the second board of education is fixed on by fixed block on supporting rod, can continue to teach using the second board of education
It learns.
The beneficial effect comprise that：Compared with traditional technology, board of education provided by the invention can be adjusted arbitrarily,
Facilitate classmate's viewing below, while fixed second board of education can not wiping in the first board of education when topic amount is excessive
Content facilitates classmate to understand.
