Description

A kind of board of education

Technical field

This utility model relates to electronic instruction apparatus field, is specifically related to a kind of board of education.

Background technology

At present, the board of education that tradition is used mostly, it is typically all and is made up of surface plate, write by chalk and carry out education activities, this kind of board of education is the most reflective, harm vision and cannot use the electronic equipment such as projection of multimedia technology, and the chalk dust that chalk-writing produces is more, healthy to user brings harm, but some teachers get used to again tradition chalk-writing.In order to realize again can be with Digital Teaching on the premise of not changing teacher's tradition writing style, make board of education can meet the requirement of chalk-writing, can meet again by electronic computer and projector with the use of imparting knowledge to students, the board of education of prior art is improved by inventor.

Utility model content

Drawbacks described above and problem for prior art, technical problem to be solved in the utility model is to provide a kind of board of education, this board of education realizes liquid and writes and chalk-writing dual combination, while solving the reflective problem of board of education, it is possible to achieve On The Projection in electronic instruction.

In order to achieve the above object, the following technical scheme of this utility model offer:

A kind of board of education, including the cream-coloured plate being arranged on sheet frame and green plate, panel that described cream colour plate includes being arranged in sheet frame, liner plate, backboard, panel, backboard are pasted with liner plate respectively, and panel surface is honeycomb texture, use the sub-electrostatic of alloy particle to paint sprayed coating, sprayed coating at least one of which, panel that described green plate includes being arranged in sheet frame, liner plate, backboard, described panel, backboard paste with liner plate respectively, and described liner plate arranges the trickleest independent hole-closing structure.

In technique scheme, described sprayed coating five layers.

In technique scheme, described panel back and backboard front are respectively provided with reinforcement groove.

In technique scheme, described green plate is spray paint on galvanized steel plain sheet, and finish paint is through hot setting.

This utility model uses cream colour plate and green plate composition, and cream colour plate panel surface uses cell layout, allows the softer dispersion of projection ray, ensured each corner no-reflection of class；And use plate face wavelength micro light quantum technology between 550-770 nanometer, it is possible to use liquid chalk dust-free writing；Green plate both can use liquid chalk to realize dust-free writing, tradition chalk-writing can be used again, during with Gypsum Fibrosum preparata or calcium carbonate chalk-writing, answer that feel is smooth, enrich, person's handwriting is uniform, writing is clear, non-slip, and come and go wiping secondary with dry type floss brush, leaving no residue writing, wiping is light, and chalk dust easily falls, Dust Capacity significantly reduces.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is structural representation of the present utility model.

Wherein: 1, cream colour plate；2, green plate；3, sheet frame.

Detailed description of the invention

Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.

According to Fig. 1, as a kind of board of education shown in embodiment, including the cream-coloured plate being arranged on sheet frame and green plate.

Cream colour plate color is ecru, sub-light, thickness >=0.43mm, and panel that cream colour plate includes being arranged in sheet frame, liner plate, backboard, panel surface is honeycomb texture, uses the sub-electrostatic of alloy particle to paint sprayed coating, and sprayed coating is five layers.Plate face wavelength is between 550-770 nanometer, and liner plate uses protection against the tide, sound-absorbing, the polystyrene foam plate of high intensity, liner plate thickness >=18mm；Backboard uses the antirust hot-dip galvanizing sheet steel of high-quality, thickness >=0.27mm；Panel, backboard are pasted with liner plate respectively, use environmental protection polyhydric alcohol glue, mechanized production, high temperature one-shot forming, be simultaneously respectively provided with reinforcement groove at panel back and backboard front during stickup, reinforced panel, backboard respectively with liner plate stickup degree.Cream colour plate is non-reflective in any angle, minimum to human eye vision pressure, effectively protection teachers and students' vision.100% dust-free writing, protection environment and teachers and students can be realized healthy, and can effectively extend the service life of electronic instruction equipment.Cream colour plate writing surface is smooth, coating uniform, wear-resisting, resistance to compression, and justifying, without splicing, can have both projection screen, electronic whiteboard, it is achieved multimedia teaching function.

Panel that green plate includes being arranged in sheet frame, liner plate, backboard, green plate panel, green backboard plate paste with green plate liner plate respectively, and described green plate liner plate arranges the trickleest independent hole-closing structure.Green plate is spray paint on galvanized steel plain sheet, and finish paint forms through hot setting, and green plate panel bare board thickness is at more than 0.25mm, plate face color is blackish green, and entire plate complexion is adjusted consistent, no-reflection, moistureproof, anti-skidding, indeformable, liner plate uses polystyrene foam sheet, and thickness is not less than 20mm, having trickle independent hole-closing structure, heat conductivity is low, does not absorbs water, ageing-resistant, corrosion-resistant, surface layer is smooth, without folding line, indeformable.
