Description
Technical field
The utility model belongs to instructional device technical field, more particularly to a kind of Composite blackboard.
Background technology
The blackboard used in teaching is all to utilize coarse surface so that chalk is ground into powder in writing process
Shape, adsorb and wiped the powder adsorbed on blackboard surface using blackboard eraser in the surface of blackboard formation word, erasing, but often
The problem of blackboard of rule is all flown upward in the presence of a chalk powder.Substantial amounts of dust can have a strong impact on the health of Faculty and Students.
Most of existing blackboard is fixed, after teacher writes plate face completely, is write again after need to being wiped, together
When in explanation, to utilize the content above write, but erased, as a result context can be caused divergence to be present；Due to
It is new knowledge that the content of explanation is most of, and student can not remember completely in a short time sometimes, certainly will cause teacher to involved
Content is write again, carries out coherent explanation；It has impact on teaching process and efficiency.
The content of the invention
To solve above-mentioned problem, the utility model provides a kind of simple in construction, easy to install, raising work
The Composite blackboard of efficiency.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of Composite blackboard, is provided with slide rail and glidepath；Multiple upper hopper chutes are provided with the upper slide rail；Glidepath is opened
There are multiple gliding grooves；Each upper hopper chute corresponds with gliding groove and is in same plane；Connected between upper hopper chute and gliding groove
There is blackboard panel；The blackboard panel corner has been bolted movable pulley；The movable pulley is contained in upper hopper chute and downslide
In groove；The blackboard panel quantity and the quantity of upper hopper chute or gliding groove match；The length of the upper slide rail and glidepath is
More times of blackboard panel length；The width of the upper hopper chute and gliding groove and the thickness of blackboard panel match；
Elastic rope is bolted on the glidepath；The stretch cord front end bolt has wiping board；On the wiping board
It is pasted with cleaning sponge brush.
Further, the glidepath side has been bolted header tank；The header tank bottom is welded with drain valve.
Further, 2~4 upper hopper chutes are provided with upper slide rail.
Further, the glidepath side has been bolted parcel tray；The wiping board is shelved in parcel tray.
The utility model has the advantages and positive effects of：Composite blackboard is simple in construction, easy to use, more by setting
Block blackboard, can solve the interior of writing and have continuity, be easy to teacher to carry out context linking explanation, avoid the fiber crops of Palingraphia
Tired, blackboard panel can be used existing conventional material, and cost is relatively low；Carried out by the movable pulley of blackboard panel in upper gliding groove
Light push-and-pull；
Appropriate water is dipped in using cleaning sponge brush to be wiped, and is avoided dust from splashing, is protected the body of teacher；After wiping
Blackboard panel rate of drying can meet writing needs.
By setting 2~4 blackboard panels, area needed for the content of whole classroom professor can be met.
