A kind of adjustable moving formula multimedia show automatic machinery people
The present invention relates to multimedia teaching facility field, specifically a kind of adjustable moving formula multimedia show automation
Existing multimedia presentation device include by infrared touch technology, intelligent software, multimedia network communication technology,
The multinomial technological synthesis such as high definition flat panel display incorporates projector, electronic whiteboard, computer, TV, touch function in one
Etc. plurality of devices in the Multifunction interdynamic teaching equipment of one, traditional display terminal can be promoted to full-featured man-machine
Current teaching is had the following problems in use with multimedia presentation device:
(1) occupied space is larger, without using when need larger space to be stored, and it is mobile inconvenient, be moved through
It is easy to cause and collides in journey；
(2) other devices of blank and equipment make a relative move, not can guarantee the indoor all students of religion can see it is pure
Content on plate；
(3) projector cannot carry out folding and unfolding according to actual use situation, be easy to damage it in moving process.
In order to improve to existing all-in-one machine for multimedia teaching, there are some explorations and reality in the country in terms of relevant apparatus
It tramples, the Chinese invention patent that number of patent application is 201711025984.9 discloses a kind of multimedia teaching dais, more matchmakers
Body Lectern for teaching, can be in use process by rotating clockwise the second threaded rod, so that terminal pad drives idler wheel downward
Dais cabinet is propped up in movement, so that support leg disengaging is moved easily, can slide into first sliding groove rear defence when computer all-in-one machine
Only computer all-in-one machine lower half portion run-off the straight causes the destruction to computer all-in-one machine, improves the protection energy to computer all-in-one machine
Power, to solve the problems, such as that multimedia teaching is had a single function with dais, is complicated for operation while not having tamper-proof；Patent application
Number a kind of touch all-in-one machine for multimedia teaching is disclosed for 201310038027.5 Chinese invention patent, an electricity is used only
Line power supply in source can allow all-in-one machine for multimedia teaching to realize the various functions such as TV, computer, touch-control, have overall structure letter
Advantage single, low in cost and easy to operate has great economic value and social value, is suitable for promoting the use of.But
The above problem can not be still fully solved, it is therefore necessary to be directed to these problems, provide a kind of adjustable moving formula multimedia show from
Dong Hua robot.
