The gear of conjunction；
The protective plate is connected on pedestal by screw thread；
When motor driven gear rotates, the gear in rotation can creep up and down along rack gear, so that pedestal is along on slide bar
Lower movement, so that protective plate be driven to move up and down.
The utility model is further arranged: the pedestal includes transverse slat and riser, and the transverse slat and riser are vertically arranged.
The utility model is further arranged: the motor is fixedly connected on transverse slat, and the protective plate is threadedly connected to perpendicular
On plate.
The utility model is further arranged: the protective plate is a kind of transparent tempered glass.
The utility model is the utility model has the advantages that the protection mechanism is set in laboratory table, can be according to protection height in experiment
Actual demand, protective plate is adjusted to by suitable position by elevating mechanism, under the premise of not influencing Germicidal efficacy, can guarantee
Protective plate after experiment, can be declined up to being hidden in laboratory table, can be well protected the mechanism by the safety for learning Germicidal efficacy person
In protective plate, and be convenient for laboratory table carrying；It is sheathed on slide bar by the double sliding sleeves being arranged on pedestal, so that elevating mechanism
It can smoothly be operated on fixed frame during oscilaltion；Wherein elevating mechanism is fixed on the transverse slat of pedestal using motor
On, motor-driven gear, wheel and rack engagement is moved up and down along rack gear, and structure is simple, stablizes, easy to operate.
