And switch S2；Resistance R3 is connected between the input terminal and power supply of triode Q3；It is connected between the control terminal and power supply of triode Q3
Switch S2 and resistance R4；Resistance R5 and capacitor C1 is connected between node and ground between switch S2 and resistance R4；Triode Q3
Output end and ground between connect inductance L1, connect two between the output end of triode Q3 and the second controlled end of relay REL1
Pole pipe D3.
Inductance L1 is set on locking pin 87, for providing to locking pin 87 far from the magnetic attraction on 82 direction of phantom ring；
When motor 84 starts turning, since relay REL1 is connected, inductance L1 obtains power supply by diode D3, and locking pin 87 is inhaled
It rises, so that the rotation to outer sleeve 51 be avoided to impact；Complete rotation reset after, due to relay REL1 power loss and make
Locking pin 87 discharges automatically, and wears in lockhole 824；When the locking for the pin 87 that needs to unlock, to adjust display 60
When angle, by touch switch S2, after capacitor C1 is passed through charge, triode Q3 constant conduction is enabled for a period of time, to enable inductance
L1 is persistently powered whithin a period of time and keeps picking up locking pin 87.
In a wherein embodiment, multimedia classroom equipment 100 further includes connecting host and the connection of display 60
The projector of host；Content synchronization to be shown will be needed to show on display 60 and projection screen.
It in the present embodiment, is set in upright bar by outer sleeve, rotate deck can relative to upright bar, adjust the angle of display
Degree；Since support plate and supporting table are correspondingly arranged, and the extending direction of upright bar is vertical with the table top of supporting table, so that teacher is standing
It can be directly facing display under state, reduce the movement bowed, while the student under facing the platform can be kept.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
