Description
Technical field
The present invention relates to realia technical field, multimedia course is adjusted in more particularly to a kind of myopia prevention
Table.
Background technique
Desk when learning as a kind of student essential equipment play great effect, desk usually by desktop,
Drawer and table leg etc. are constituted, and usually double desk and structure is single, function is simple when old-fashioned desk design nowadays learns
Raw to be often made with individual single desk, when figure smaller use, is pleasant and does not allow to easily cause interference between student,
Quiet studying space can be provided, although Modern desk is more humane since the learning tasks of nowadays student are numerous
Weight, all kinds of data are various, therefore demand is often not achieved in single desk on usable floor area, causes students' union data such as books
It is placed on the ground；
Desk in existing use is generally divided into two kinds, and one is fixed heights, another is lift,
In, the desk of lift is because its height is adjustable, increasingly by the welcome of students.But lift class in the prior art
Table, its lifting are fixed mainly by screw, and height will be adjusted every time with spanner by adjusting, and tune that can only be one grade one grade
Section, that is to say, that the adjusting of Desk capable for rising and falling height is not only time-consuming and laborious in the prior art, and degree of regulation cannot be guaranteed.
With advances in technology with the continuous development of multimedia teaching, the desk teaching facilities one of indispensable as teaching,
Under present educational environment, also have higher requirement, as display is more more and more universal, traditional desk having a single function
The requirement of multimedia teaching is can not meet, and myopia problem is also increasingly severe, student is teaching indoor incorrect sitting posture
The main reason for often causing myopia, with the limitation in classroom space, top class in a kindergarten's education is indispensable in modern education
Mode of learning, still, with the increase of classroom number, classroom area is larger, between teacher and student interactivity it is poor, in after
The student for arranging seat may influence quality of instruction due to too far from teacher, difficult with teachers.
Therefore, how a kind of expansible desktop, myopia prevention, the manageable multimedia desk of desk height Adjustment precision are provided
The problem of being those skilled in the art's urgent need to resolve.
Summary of the invention
In view of this, the present invention provides a kind of myopia prevention be adjusted multi-media desk, can easily consolidate to desktop
It is expanded, to solve the disadvantage of desk usable floor area deficiency；And height of table top is easily adjusted, and Adjustment precision is easy control
System；Meanwhile having myopia prevention function to remind sitting posture of student for foundation at a distance from desk by acquisition student
Can, it is also equipped with multimedia display function, enhances the interaction between teachers and students, further promotes quality of instruction.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of adjustable multi-media desk of myopia prevention, comprising: desktop, book end, table leg and drawer；Wherein the book end is set
It sets on the desktop, the drawer and the table leg are connected to the desktop bottom；
The centre of the desktop offers display tank, and display tilt adjustment is arranged in the two sides of the display tank
Plate is arranged with several tilt adjustment holes on the display tilt adjustment plate；Described display tank a side is hinged with display
Device installation base plate；Flexible display screen is equipped on the display installation base plate；Display installation base plate two sides are hinged with
Bracket, the cantilever tip and display installation base plate two sides are hinged, and the tilt adjustment hole is inserted into the bracket bottom end
In；
When not using multimedia function, the display installation base plate is located at the display together with the flexible display screen
In tank, display can be kept to clean, continue to use when desk, the display is installed into base when using multimedia function
Plate goes out together with the flexible display screen from the display tank varus, and by the bottom end of the bracket and the different tilt adjustments
Hole cooperation carries out tilt adjustment.
Flexible display screen is made of soft material, the flexible display device of changeable type.It is as thin as paper, even if cutting
Power down source, content will not disappear, and be also designated as " Electronic Paper ".
