Description
Technical field
The utility model belongs to schooling apparatus technical field, relates in particular to a kind of myopia prevention desk for study.
Background technology
In students, myopia number is more and more, myopia taking for a long time with a hypotelorism causer as common.The adjusting power of teenager's eyes is very strong, still can see object in the time that the distance of books and eyes reaches 7-10 centimetre clearly, if but often with this apart from reading, write and will make the dysregulation anxiety of eyes, thereby can form refrangibility myopia, be i.e. so-called pseudo-myopia; If long-term accommodative excess, ciliary muscle can not be stretched flexibly, strengthen because accommodative excess causes converge like the spokes of a wheel at the hub effect, extraocular muscle is exerted pressure, increased intraocular pressure to eyeball, eye inner tissue's hyperemia, add that teenager's eyeball organizes tender and lovelyly, wall of eyeball pressurized extends gradually, and eyeball antero posterior axis is elongated, exceed normal value and just formed axial myopia eye, be i.e. so-called true myopia.
How the study table using in school is made up of table and table leg, because learning time is longer, add that control is poor, some student is in reading, the distance of eyes and book can be more and more nearer in spite of oneself while writing, even climb reading on desk, write, be easy to like this cause for a long time myopia.
Utility model content
Technical problem to be solved in the utility model is: the deficiency existing for prior art, provide a kind of simple in structure, and can prevent the myopia prevention desk for study that eyes and books distance are too near.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of myopia prevention desk for study, comprises table and for supporting 4 table legs of table, a side of described table is provided with joint pin, and the free end of described joint pin is provided with the gear plastron parallel with a side of described table; The opposite side that described table is relative with described gear plastron is provided with acclivitous support column, and the free end of described support column is positioned at the top of described gear plastron, and the free end of described support column is provided with fastener plate.
Improve as one, described support column is retractable supports post, and described retractable supports post comprises support bar and be located at the extension rod in described support bar, and described extension rod is provided with the adjusting button for fixing described extension rod.
As improving further, described support column and described table are hinged, described table is provided with the support column standing groove and the fastener plate standing groove that are respectively used to hold support column and fastener plate, on described support column standing groove and fastener plate standing groove, is respectively equipped with dismountable groove lid.
Preferably, the angle between described support column and described table is 35～45 °.
Preferably, the length of described joint pin is 1～2cm.
Owing to having adopted technique scheme, the beneficial effects of the utility model are:
A kind of myopia prevention desk for study that the utility model provides, comprise table, table leg, gear plastron and fastener plate etc., it is simple in structure, gear plastron can ensure student reading, while writing and table maintain a certain distance, avoid from table too close to and climb in spite of oneself on table; Fastener plate can be used for preventing that student's head from leaning forward and causing eyes and books apart from too near, between support column and table, be certain rectifiable used by students during reading of angle, correct body position while writing and between books, height after the scalable people of being convenient to different heights of support column sits down according to oneself regulates the distance between head and desk, thereby its head is contacted with fastener plate just; In not using support column and fastener plate, support column and fastener plate are closed in support column standing groove and fastener plate standing groove, take up room thereby reduce.This myopia prevention desk for study is simple in structure, easy to use, can avoid student's eyes and books distance too near, pre-Anti-myopic eye.
