Abstract
The invention discloses a folding blackboard. The folding blackboard comprises three blackboard bodies and universal wheels. The three blackboard bodies comprise a large-scale rectangular blackboard body and two small-scale blackboard bodies. The two small-scale blackboard bodies are symmetrically distributed on the two sides of the large-scale rectangular blackboard body, the two small-scale blackboard bodies are connected with the large-scale rectangular blackboard body through positioning hinges, and the universal wheels are arranged at bottom corners of the two small-scale blackboard bodies. The folding blackboard has the advantages that the blackboard is split into three pieces of blackboard bodies and the three pieces of the blackboard bodies are combined in the mode of the positioning hinges, and in a folding state, the carrying is very convenient; meanwhile, the universal wheels are arranged on the bottom of the blackboard, the movement of the blackboard is convenient, the blackboard surface can be protected well, and the service life of the blackboard is prolonged.
Description
Technical field
The present invention relates to a kind of folding blackboard, belong to educational aid field.
Background technology
Blackboard, as the indispensable teaching aid of one, along with the development in epoch, the kind of blackboard also gets more and more, and the feature of blackboard mainly contains: the rich prosperous logical green plate plate face of green plate blackboard is blackish green, with chalk-writing, do not stimulate the eyes of people, be 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, the fixing small-sized educational aid such as magnetic patch 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, be equipped with electronic whiteboard, projector, computer, and corresponding teaching software, hardware perfectly supplements the defect in conventional teaching, modernized teaching reform is allowed really to walk to enter the classroom, for the inexorable trend of current development of educational cause. Glass blackboard, Guangzhou shepherd boy's Glass blackboard uses ground glass to make, because it is frangible, Dust Capacity is 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.
Nowadays, blackboard is be fixed on indoor use mostly, its volume is large, field of employment is fixed, but many times, also needs to impart knowledge to students in outdoor, and the blackboard for education of the outdoor application of present stage, a just very common panel, namely inconvenient in the process of carrying, also likely can cause damage on blackboard surface thus affect service life of blackboard.
Summary of the invention
The object of the invention is to overcome weak point that prior art exists and provide a kind of folding blackboard.
For achieving the above object, the technical scheme taked: a kind of folding blackboard, comprises three blackboards and universal wheel.Described three blackboards comprise a large-scale rectangular blackboard and two small-sized blackboards.Described two small-sized blackboards are symmetrically distributed in described large-scale rectangular blackboard both sides, and two small-sized blackboards are connected with described large-scale rectangular blackboard by Positioning hinge.Described two small-sized blackboard base angles are provided with universal wheel.
Helpfulness of the present invention is: the invention provides a kind of folding blackboard; blackboard is split into three pieces; and their modes with Positioning hinge are combined; under rugosity state, very convenient to carry, simultaneously; universal wheel is provided with bottom blackboard; the movement of Convenient blackboard, and well can protect blackboard surface, extend the service life of blackboard
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of folding 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 folding blackboard as shown in Figure 1, comprises three blackboards and universal wheel 4.Described three blackboards comprise large-scale rectangular blackboard 1 and two small-sized blackboards 2.Described two small-sized blackboards 2 are symmetrically distributed in described large-scale rectangular blackboard 1 both sides, and two small-sized blackboards 2 are connected with described large-scale rectangular blackboard 1 by Positioning hinge 3.Described two small-sized blackboard 2 base angles are provided with universal wheel 4.Blackboard is split into three pieces, and their modes with Positioning hinge 3 are combined, under rugosity state; very convenient to carry, meanwhile, bottom blackboard, be provided with universal wheel 4; the movement of Convenient blackboard, and well can protect blackboard surface, extend the service life of blackboard.
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.
