Description
Technical field
The utility model relates to field of Educational Technology, is specially a kind of board for teaching mathematics.
Background technology
At present, teacher is in mathematical education process, usually make graphically to resolve mathematics examination question, be difficult to again, indigestibility abstract to some in the process, the mathematics examination question of difficult memory carries out chart teaching, and time distant, student is below difficult to see, sometimes also do not hear clear, be difficult to help student to understand and memory mathematics examination question, teacher makes chart when imparting knowledge to students, not only require great effort, but also valuable instructional blocks of time can be wasted.For a long time, in teaching, chalk dust contaminated environment, numerous teachers and students endure dust injury to the fullest extent, and tuberculosis becomes the occupational illness of teacher, is also the number one killer of teachers ' health problem.Although people are devoted to develop so-called dust-free chalk always, owing to fundamentally not changing the writing on the blackboard mode of teachers ' teaching, so so-called dust-free chalk not only had dirt in the past, and write painstakingly hard, use extremely inconvenient.The drawing board for teaching utilizing liquid pens to carry out writing becomes the important apparatus in teaching gradually.And the chart board size of existing teaching is all fixing, if usable floor area is inadequate, cannot continuing to write or pinup picture, needing to wipe writing appearance in above, can not wipe if content is above very important, just allow teacher feel difficult, in addition, the article such as teaching aid are mostly be placed in lectern, because other the thing such as file more may be deposited in lectern, not easily find when fetching, so also delayed a lot of time, be unfavorable for teaching.
Utility model content
The purpose of this utility model is to provide a kind of board for teaching mathematics, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme a kind of board for teaching mathematics, comprise LED box and bracing frame, described LED box is arranged on bracing frame top and LED box is rectangular parallelepiped, support frame as described above through the middle part of LED box, and rotates centered by bracing frame, and described LED box front is provided with LED full-color screen display, described LED full-color screen display is connected with playback equipment, and described LED box bottom is also provided with receiver.
Preferably, support frame as described above comprises pulley, base, upper expansion link and lower expansion link, and described upper expansion link is flexibly connected with lower expansion link and lower expansion link is fixedly connected with base.
Preferably, described base is fixedly connected with four pulleys.
Preferably, the two sides of described LED box and the back side are provided with digital card, picture card and operation sheet by draw-in groove.
Preferably, described LED box is connected with desktop computer or laptop computer.
Compared with prior art, the beneficial effects of the utility model are: this board for teaching mathematics has reasonable in design, structure is simple, easy to use, function admirable, the features such as practicality, pass through bracing frame, and LED box is rotated around bracing frame, because LED box is rectangular parallelepiped, wherein a face in front is provided with LED full-color screen display, LED full-color screen display is connected with playback equipment, other three sides are separately installed with digital card, figure card, operation sheet, Continuous Play can be carried out by playback equipment, and carry out diagram by card, achieve conveniently, efficiently, time saving and energy saving effect, be convenient to carrying out smoothly of teaching, improve efficiency of teaching.
