Description
Technical field
The invention belongs to board technical field, more particularly, to a kind of Novel free wiping teaching tablet.
Background technology
At present, in teaching adopt blackboard, chalk as educational aid, blackboard be coated by plank or cement plate surface pitch-dark
Or be made up of the focussing glass of lining black matrix；At present, blackboard can only by Calx for primary raw material chalk-writing, dust is very big, learns
After raw and teacher sucks, have a strong impact on healthy.As disclosed in the patent No. 201120429753.6, a kind of board, employs
Watercolor pencil is imparted knowledge to students, but also needs to be wiped, and watercolor pencil price is higher, is also unfavorable for environmental protection, improves and uses into
This.Therefore, it is necessary to design is a kind of automatically the word that writer is write on board can be carried out auto-erasing, it is effectively improved
Writer's surrounding, and substantially reduce use cost, the Novel free more preferably meeting the needs of writer wipes teaching tablet, becomes
The direction made great efforts for those skilled in the art.
Content of the invention
The present invention provides a kind of Novel free to wipe teaching tablet, and this Novel free is wiped teaching tablet and is easily installed and dismantles,
Easily clean, outward appearance beautiful, fastness is good, is effectively improved writer's surrounding, improves viewing board angular field of view and clear
Degree.
For reaching above-mentioned purpose, the technical solution used in the present invention is：A kind of Novel free wipes teaching tablet, including having
The substrate of black upper surface, the pad pasting that writes, upper side frame and lower frame, described upper side frame and lower frame are respectively arranged in the upper of substrate
On end face and lower surface, this upper side frame and the opposite side of lower frame are respectively arranged with upper hopper chute, gliding groove, this upper hopper chute, under
Top sheave, lower sheave it have been respectively embedded into, a litter one end is arranged on top sheave, and this litter other end is arranged on downslide in chute
On wheel, the described pad pasting that writes is made up of with the gluing oxidant layer of micropore being coated on polyester film surface mylar, micropore adhesive
Layer is located at the mylar surface opposite with substrate, and described mylar two ends are respectively arranged with first, second bending part, described
Litter is located at below mylar or first, second bending part, the upper surface of described mylar and micropore adhesive layer
It is evenly distributed with several upper projecting portion, the lower surface that described mylar oxidant layer gluing with micropore contacts is evenly distributed with some
Individual lower convex portion, the section of described litter is trapezoidal faces and the angle carving angle being located at litter two ends is 30 ° ~ 50 °.
In technique scheme, further improved technical scheme is as follows：
1st, in such scheme, the thickness of the gluing oxidant layer of described micropore is 20 μm ~ 60 μm, pore density is 1000 ~ 3000/
Cubic centimetre
2nd, in such scheme, the thickness of described mylar is 75 μm ~ 200 μm.
3rd, in such scheme, 180 ° of adhesion strengths to glass of described micropore adhesive are 0.5 ~ 1.5N/inch.
4th, in such scheme, described first, second bending part and substrate angle are 10 ° ~ 30 °.
In 5 such schemes, the following table surface roughness of described mylar is 1.0 μm～3.0 μm of surface.
Because technique scheme is used, the present invention compared with prior art has following advantages：
Novel free of the present invention wipes teaching tablet, and its structure is simple, and reasonable in design, low production cost is easily installed and tears open
Unload, easily clean, outward appearance is beautiful, and fastness is good, automatically the word that writer is write on clipboard can be carried out auto-erasing, have
Effect improves writer's surrounding, and both substantially reduces use cost, also reduces pollution；Secondly, its mylar two ends is divided
It is not provided with first, second bending part, described litter is located at below mylar or first, second bending part, during convenient use
Mylar is quickly peeled off by operator, improves efficiency of erasing；Again, the upper table of its mylar and micropore adhesive layer
Face is evenly distributed with several lobe, thus forming roughness in this upper surface is 1.0 μm～3.0 μm of surface, both and can
Enough improve the sense of touch that the pad pasting that writes is write, improve viewing board angular field of view and definition, simultaneously because the section of litter is
Trapezoidal faces, during convenient use, mylar is quickly peeled off by operator, improves efficiency of erasing.
