To achieve the above object, the utility model provides following technical scheme：A kind of liftable imparted knowledge to students using full of beard political affairs
Curtain, including mounting seat, electric pushrod, bearing, shell, curtain, block, rotating shaft, motor, No.1 switch and No. two switches, two
The bottom of the individual mounting seat is provided with an electric pushrod, connects at the top of the bottom of described two electric pushrods and shell
Connect, a bearing is installed inside the side of the shell, a motor is installed inside the opposite side of the shell, it is described outer
Shell is internally provided with a rotating shaft, and the side of the rotating shaft connects with the side of motor, the opposite side insertion of the rotating shaft
Bearing, the rotating shaft connect with the top of curtain, and the bottom of the curtain is provided with a block, the motor by wire and
No.1 switch connection, the electric pushrod pass through wire and No. two switch connections.
Preferably, the both sides of the top connection curtain of the block are each provided with one piece of filter pulp.
Preferably, the electric pushrod is apparatus capable of fluctuating, and Liftable scope is 0-60cm.
Preferably, the surface of the curtain scribbles one layer of protection materials.
Preferably, the mounting seat is horizontal and vertical is provided with four mounting holes.
Compared with prior art, the beneficial effects of the utility model are：This sets using the drop scene of full of beard political affairs teaching
There is a block, the both sides of the top connection curtain of block are each provided with one piece of filter pulp, and when curtain is retracted to top, filter pulp can be
The opening of outer casing bottom is sealed completely, prevents dust from entering internal, when needing to use the blackboard behind curtain, can directly make
Electric pushrod is controlled to drive shell to move up with No. two switches, the rate of climb is very fast, saves lecture time, and the surface of curtain applies
There are one layer of protection materials, increase service life, it is easy to use, design more hommization.
