Description
Technical field
The utility model belongs to teaching equipment technical field more particularly to a kind of no dust blackboard.
Background technique
The design defect of traditional automatic blackboard is to design automatic board-wiping before writing panel but also be external
Boundary's environment open wide, then realized with power supply and its some mechanisms blackboard-cleaning is clean, it is caused the result is that not to dust
It is handled, and because the mobile teacher of wiping board or student cannot continue to write on blackboard in wiping process, so for
The considerations of to this two o'clock, the utility model optimized it, needed to design without dust blackboard.
In conclusion problem of the existing technology is: dust is flown upward everywhere during traditional automatic blackboard wiping, is not had
Have and dust is handled, and because the movement of wiping board, teacher or student cannot continue to write on blackboard in wiping process.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of no dust blackboard.The nothing of the utility model
For dust blackboard when plate face writes, teacher, which starts motor, can be realized blackboard automatic erasing out handwriting, during erasing out handwriting
Do not influence teacher attend class and accomplish non-dusting without dust blackboard.
The utility model is realized in this way a kind of no dust blackboard, installed in the writing plate face of the no dust blackboard
There is panel transmission mechanism；The rear end for writing plate face is equipped with rear cover and clashes mechanism, rear cover wipe wiping board in mechanism with
Rotated panel is close to, and drives wiping board or so to move back and forth erasing out handwriting by the second motor and threaded guide rod；
The panel transmission mechanism is provided with the first motor；First motor is located at the upper of panel transmission mechanism
Side, is connected with master rotor by first bearing；The master rotor is connected by toothed belt with from roller；
The rear cover clashes mechanism and is provided with the second motor；Second motor is located at the rear cover that rear cover clashes mechanism
Case upper right side；Second motor is connected by toothed belt with threaded guide rod；It is socketed on the threaded guide rod by screw thread
Wiping board；Light guide bar is also socketed on institute's wiping board；
It is described to be all contained in inside back cover case with light guide bar, threaded guide rod；Light guide bar passes through second bearing and toothed belt phase
Even.
Further, the writing plate face is embedded in front of back cover case；The rear end of the back cover case is by bolt or is welded with
Blackboard mounting rod；The lower part of the back cover case is equipped with ash accepting box；The outside of the ash accepting box is by bolt or is welded with ash
Box handle.
Further, toothed belt protective shell is snapped with outside the toothed belt；The toothed belt protective shell is bolted
On back cover case.
Further, first motor is installed on the supporting plate；The support plate is mounted on writing one side of the board；It is described
The support of bearing for fixing first bearing is installed in support plate.
The advantages of the utility model and good effect are as follows:
Traditional automatic blackboard erasing mechanism is arranged before the panel that writes, and such design waste that both interferes to write is attended class
Dust can not be carried out processing by the time influences teachers and students' health.So both having been had the advantage that without dust blackboard
It 1, is a kind of automatic blackboard without dust blackboard, i.e., when teacher thinks erasing blackboard writing, teacher's starting first is electronic
Machine, the second motor that panel back is arranged in after rotation start automatically, in the work of timing means and the positive deinstall of control
It can be wiped free of completely with lower writing, be raced against time in the process since the panel rotation time is short to attend class for student；
2, without the subsequent erasing mechanism of dust blackboard using Seal Design, for preventing dust from flying everywhere, a timing
Between after ash accepting box can be removed and outwell dust, to protect the health of teachers and students.
