Plug moves up along the madial wall of pressure box, and piston can be pumped into air by escape pipe and enter in pressure box, work as writing
Needed after the content displaying of blackboard during declining to it, due to the mouth of pipe very little of escape pipe so that writing blackboard exists
Move down, writing blackboard drives push rod to move down and moved down with piston, is write under the active force of atmospheric pressure
Blackboard slowly declines, and writing blackboard is played a part of adequately protecting.
Because also including travel switch, travel switch is equipped with the top and bottom of fix bar, motor and electromagnet are equal
There is circuit to be connected between travel switch.When writing blackboard rises to top, writing blackboard touches travel switch so that
Cam is closed, while work of electromagnet is controlled to the position of writing blackboard, when writing blackboard drops to certain position, book
The bottom for writing blackboard touches travel switch, and now the circuit of electromagnet is closed, and retaining ratchet and feeding ratchet seesaw ratchet reset, while electricity
The circuit of machine is connected, and motor can drive writing blackboard to run again, so operate repeatedly, you can written contents is carried out continuous
Displaying and carry out other operations.
Because also including indicator lamp, frame roof is provided with indicator lamp, there is circuit connection between indicator lamp and travel switch.
When travel switch at the top of fix bar works, indicator lamp lights, you can and the content displaying on prompting people's writing blackboard finishes,
When the travel switch work of bottom of fixed, indicator lamp lights, and prompts people's writing blackboard to reset.
Because also including control valve, escape pipe is provided with control valve.Control valve can further control the exhaust of escape pipe
Amount, prevent the decrease speed of writing blackboard is excessive from causing greatly to impact in itself to protection spring and writing blackboard.
（3）Beneficial effect
The present invention carries out lifting, so as to in writing by the mutual cooperation of toggle mechanism and non-return mechanism to writing blackboard
Appearance is shown, reached can improve teacher teaching efficiency, accelerate student thinking, improve classroom Learning atmosphere effect
Fruit.
