In described casing, be provided with the drive unit that can drive desktop up and down, described drive unit comprises the motor cabinet being fixed on box bottom, on described motor cabinet, be fixedly connected with motor, one side of motor cabinet is fixedly connected with support, on support, be fixedly connected with decelerator, between the output shaft of described motor and the power shaft of decelerator, be connected by shaft coupling, on described decelerator, be fixedly connected with supporting seat, the output shaft of described decelerator is fixedly connected with adapter sleeve through supporting seat, in described adapter sleeve, be provided with leading screw, described leading screw is fixedly connected with adapter sleeve by bearing pin, described leading screw is connected with mother lead screw away from one end of adapter sleeve, on described mother lead screw, be fixedly connected with connecting plate, described connecting plate is fixedly connected with desktop by attaching nut.
Below further improvement of the utility model:
The outside of described adapter sleeve is provided with the boss of annular, between described boss and supporting seat, is provided with thrust bearing, and described thrust bearing is sleeved on the output shaft of decelerator.
Further improve:
One end near mother lead screw on described leading screw is provided with limited block.
The utility model adopts technique scheme, simple in structure, can adjust according to the teacher of different heights the height of desktop, in the time need to adjusting the height of desktop, starter motor, the running of driven by motor decelerator, the output shaft of decelerator drives leading screw to rotate, and leading screw drives mother lead screw to move up and down, and mother lead screw drives connecting plate motion, the upper and lower easy motion of connecting plate, drives the moved up and down adjusting of height of table top of desktop; Shelf is used for placing books, because shelf is to be obliquely installed therefore can ensure that teacher's sight line is vertical with books, easy-to-read; Drawer can be used for placing various teaching aids; After the setting of audio amplifier and microphone can facilitate, row's classmate clearly hears teacher's sound.
