Description
Technical field
The utility model relates to teaching field, is one of indispensable educational aid self-cleaning dust-free blackboard.
Background technology
In numerous instructional media, blackboard is the most used, the easiest, the most most economical one instructional media routinely of classroom teaching.Although highly modern audio-visual media, multimedia computer and network technology etc. pour in classroom, but from the present situation of China's teaching practice level, also can replace blackboard completely without any a kind of instructional media, particularly in some middle and primary schools, the teaching process of teacher almost places one's entire reliance upon blackboard.But existing blackboard in use, and dust flies upward, drastically influence the healthy of academics and students everywhere, and in the process erased the board, waste the class period.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of self-cleaning dust-free blackboard.Thus realize effectively dust-proof and time saved on classroom shared by blackboard wiping.
The technical scheme that the utility model adopts is: a kind of self-cleaning dust-free blackboard, and it is made up of flexible blackboard face, flexible blackboard face slack adjuster, blackboard eraser, soft hairbrush and bracing or strutting arrangement etc.Flexible blackboard face (4) is supported by the axis of rolling (3A), (3B), (3C) after two front axis of rolling (9A), (9B) and three; The axis of rolling (3A), (3B), (3C) side after three blackboard erasers (2A), (2B), (2C) are separately positioned on three; Flexible blackboard face slack adjuster (5A), (5B) is provided with after self-cleaning dust-free blackboard; The front axis of rolling (9A), (9B) blackboard eraser (2A), (2B), (2C) and the rear axis of rolling (3A), (3B), (3C) and flexible blackboard face slack adjuster (5A), (5B) are fixed by front shoe (7) rear fixed plate (6) and framework (1); Flexible blackboard face (4) are provided with soft hairbrush (8); Motor is contained in framework (1) top, power is passed to the rear axis of rolling (3A), (3B), (3C) by the worm gear (10A) on worm screw and the rear axis of rolling (3A), (3B), (3C), (10B), (10C) by motor, thus drives flexible blackboard face (4) to rotate; Backing plate (11) is welded on after the upper flexible blackboard face (4) of framework (1), with supporting flexible blackboard surface (4), is convenient to write.
Described self-cleaning dust-free blackboard, whole framework (1) is provided with dust dividing plate around, effectively prevents dust from flying around.
Described self-cleaning dust-free blackboard, flexible blackboard face (4) is provided with soft hairbrush (8), blackboard surface often rotates one week, completes the self-cleaning of the cleaning of a flexible blackboard face (4) and blackboard eraser (2A), (2B), (2C).
Described self-cleaning dust-free blackboard, blackboard eraser (2A), (2B), (2C) are set to three, three times are carried out to flexible blackboard face (4) and repeats wiping, make cleaning more clean, in addition, blackboard eraser (2A), (2B), (2C) are set to corrugated, the dust of wiping can be fallen, to improve wiping effect along gap.
Compared with prior art, the beneficial effects of the utility model are: not only structure is simple, easy to operate, can be disposable by the writing wiped clean on flexible blackboard face, and effectively prevent dust from flying around, avoid the injury of dust to human body, save teacher's blackboard wiping time used on classroom.
