Abstract
The utility model provides a desk for preventing nearsightedness. The desk is provided with a horizontal desk surface, a display, a paraboloid concave mirror, a semi-permeable mirror and a camera, wherein the display is horizontally arranged on the horizontal desk surface; the paraboloid concave mirror with the concave surface downward is arranged just above the display; the semi-permeable mirror is arranged between the display and the paraboloid concave mirror by forming an angle of 45 degrees with the horizontal desk surface; the horizontal desk surface is provided with a book placement region; the camera is arranged just above the book placement region in such a way that the shooting direction of the camera just faces to the book placement region, and the camera is connected with the display through a data line. Compared with the prior art, the desk provided by the utility model has the advantages of moving the image of a book or a computer display screen to a distant place through an optical means and enabling human eyes to be in a distant looking state during reading or writing and crystalline lenses to be relatively relaxed and exercised, thereby effectively preventing the generation and exacerbation of the nearsightedness.
Description
Technical field
The utility model relates to a kind of desk, refers to especially prevent the myopia desk.
Background technology
Existing pre-myopia prevention nothing more than being the sitting posture that adopts theory of mechanics or electronic sensor to correct a mistake, makes human eye and books remain certain distance with desk, plays certain related preventive effect.But, correcting faulty sitting posture in any case, the distance of human eye and books all near 33cm, namely belongs to the close-ups state all the time, closely stares for a long time also to cause using kopiopia, may bring out myopia or myopia degree and deepen.
Summary of the invention
The utility model proposes a kind of pre-myopia prevention desk, solved to solve for a long time in the prior art and closely stared, may bring out the shortcoming that myopia or myopia degree are deepened.
The technical solution of the utility model is achieved in that
Pre-myopia prevention desk, it is characterized in that, this desk is provided with horizontal table top, display, parabolic concave mirror, pellicle mirror, video camera, described display is horizontally set on the horizontal table top, described parabolic concave mirror concave surface is located at directly over the display downwards, described pellicle mirror and horizontal table top are 45° angle and are located between display and the parabolic concave mirror, described horizontal table top is provided with the books put area, the shooting direction of described video camera is over against described books put area, be located at described books put area directly over, described video camera is connected by data wire with display.
Described pellicle mirror and user's horizontal line of sight is 135 ° of angles.
Described parabolic concave mirror is provided with the motor drive mechanism that relative display vertical direction moves up and down.
Described display also is provided with the data-interface that is connected with computer.
Compared with prior art, the utility model has the advantage of, by optical instrument a distant place is arrived in the image drift of books or computer display screen, when reading or writing, make human eye be in the state of looking in the distance, crystalline lens relatively loosens and obtains taking exercise, can effectively pre-myopic-preventing generation and deterioration.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation that the pre-myopia prevention of the utility model is used desk.
Wherein, 1-horizontal table top, 2-books put area, 3-video camera, 4-eyes, the parabolic concave mirror of 5-, 6-motor drive mechanism, 7-pellicle mirror, 8-display, 9-imaging, the 10-virtual image
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, pre-myopia prevention desk, this desk is provided with horizontal table top 1, display 8, parabolic concave mirror 5, pellicle mirror 7, video camera 3, described display 8 is horizontally set on the horizontal table top 1, described parabolic concave mirror 5 concave surfaces are located at downwards directly over the display 8, described pellicle mirror 7 and horizontal table top 1 are 45° angle and are located between display 8 and the parabolic concave mirror 5, described horizontal table top 1 is provided with books put area 2, the shooting direction of described video camera 3 is over against described books put area 2, be located at described books put area 2 directly over, described video camera 3 and display 8 are connected by data wire.Described pellicle mirror 7 is 135 ° of angles with user's eyes 4 horizontals line of sight.Described parabolic concave mirror 5 is provided with the motor drive mechanism 6 that relative display 8 vertical direction move up and down.Described display 8 also is provided with the data-interface that is connected with computer.
Parabolic concave mirror 5 is connected on the motor drive mechanism 6 that can move up and down, change the position of parabolic concave mirror 5, the distance of picture 9 will directly be changed over, this point has vital meaning for pre-myopia prevention and visual training, can be equivalent to crystalline lens adjusted and training in reading process of user.
The motor drive mechanism 6 of parabolic concave mirror 5 can be hand-manipulated, also can work out special training program and control.
If do not need to read books or writing, also can save the video camera light path, 8 need of display this moment link to each other with PC by the computer data interface of reserving, and have used computer desk just become a myopia prevention.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
