Description

A kind of blackboard

Technical field

The present invention relates to office appliance field, relate in particular to a kind of blackboard.

Background technology

Blackboard is a kind of office accommodation, is seen everywhere in each school, and total class of blackboard is also more and more diversified, and such as, it is blackish green that Fu Xin leads to green plate plate face, with chalk-writing, does not stimulate the eyes of people, is conducive to vision protection, omnibearing visual angle; Whiteboard face is then white, and multiplex various water-based crayon is write.Blackboard panel is then black, and with chalk-writing, pen pen is clear. color coated steel sheet plate face adopts the high duty alloy steel plate being coated with wear-resistant coating, and plate face thickness mostly is 0.3mm-0.4mm, wear-resisting, do not come off, colour-fast, durable in use. write good hand touch, writing is clear, easily writes, and easily wipes examination. and dust is few; New material composite plate is left intact through disposal pressed moulding surface by import height blackboard molecular alloy particle and epoxy resin, plate face thickness is 3mm, fluent writing, writing is clear permanent non-slip, not reflective, noresidue after wiping, visual effect is splendid, reach more than 15 years service life after tested, this product is exclusively developed by blue Bei Site. surface plate plate face flat smooth, and cambered plate plate face is curved surface, prevents reflective, the student being sitting in each corner can be made also to see writing on the blackboard writing clearly, be applicable to larger classroom.Blackboard is equipped with various support by support portable plate, conveniently moving, and purposes is wide.Draw back plate lifter plate, along the multidirectional movement of certain tracks, can write conveniently, is beneficial to viewing. and magnet board serves as a contrast in blackboard inside with magnetic stripe bar magnet, or at surface attachment magnetic-particle.Can follow closely with magnetic during use, magnetic patch etc. fixes small-sized educational aid or the convenient displaying of picture. Multifunctional combined board, interactive electric whiteboard, band curtain projection plate, staff music blackboard, it is the combination of traditional blackboard and modern science and technology, traditional blackboard, is equipped with electronic whiteboard, projector, computer, and corresponding teaching software, hardware perfectly supplement the defect in conventional teaching, allowing modernized teaching reform really walk to enter the classroom, is the inexorable trend of current development of educational cause.Guangzhou shepherd boy's Glass blackboard uses ground glass to make, because it is frangible, Dust Capacity large, transport inconvenience starts market of fading out.Staff music blackboard: blackboard is applied at connection music, as the term suggests this kind of blackboard is just known as music blackboard, in this, blackboard succeeds in developing a kind of blackboard that can sing by Soviet Union scientific and technical personnel. on this block blackboard, be decorated with note.When Music Teacher with teacher's pointer by when contacting these music symbols, if blackboard will send the tone consistent with these notes. on blackboard, write a melody, when teacher's pointer is by when contacting the note of this melody, music blackboard will play out interesting to listen to song

Although total class of blackboard is various, but at present, blackboard is primarily of plate face and ledge for chalk on blackboard two parts composition, the wherein chalk dust that drops on collecting board face of ledge for chalk on blackboard, and when people clear up ledge for chalk on blackboard, rag or brush can only be used to clear up, be easy to cause dust pollution, have a strong impact on classroom health, make troubles to teachers and students.

Summary of the invention

The object of the invention is to overcome weak point that prior art exists and provide a kind of blackboard.

For achieving the above object, the technical scheme taked: a kind of blackboard, it comprises mobile device, blackboard eraser, ledge for chalk on blackboard and dust-collecting box, described blackboard eraser is installed on described mobile device, described mobile device is by crossbeam, first pulley and the second pulley are formed, the first described pulley and the second pulley are fixedly mounted on the two ends up and down of described crossbeam respectively, the rubber brush finish of described blackboard eraser is made up of wool brush finish, described ledge for chalk on blackboard is a kind of halfpipe of inclination, the comparatively low side of described ledge for chalk on blackboard is provided with dust-collecting box, the higher-end of described ledge for chalk on blackboard is provided with hair-dryer.

Beneficial effect of the present invention is: the invention provides a kind of blackboard, has structure simple, laborsaving practicality, the advantages such as easy to use, health is attractive in appearance.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of a kind of blackboard of the present invention.

Detailed description of the invention

For better the object, technical solutions and advantages of the present invention being described, below in conjunction with specific embodiment, the invention will be further described.

A kind of blackboard shown in Fig. 1, it comprises mobile device 1, blackboard eraser 2, ledge for chalk on blackboard 3 and dust-collecting box 4, described blackboard eraser 2 is installed on described mobile device 1, described mobile device 1 is by crossbeam, first pulley 5 and the second pulley 6 are formed, the first described pulley 5 and the second pulley 6 are fixedly mounted on the two ends up and down of described crossbeam respectively, the rubber brush finish of described blackboard eraser 2 is made up of wool brush finish, described ledge for chalk on blackboard 3 is halfpipe of a kind of inclination, the comparatively low side of described ledge for chalk on blackboard 3 is provided with dust-collecting box 4, the higher-end of described ledge for chalk on blackboard 6 is provided with hair-dryer 7.When needs erase the board, lightly promote crossbeam with have gentle hands, dust just can come off in ledge for chalk on blackboard 3, and a part of chalk dust slides into dust-collecting box 4 automatically, and a part can drop to dust-collecting box by the effect of hair-dryer 7, greatly facilitates the use of people.

Finally to should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention but not limiting the scope of the invention; although be explained in detail the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
