Description
Technical field
The utility model relates to a kind of pre-myopia prevention device, especially can correcting sitting postures, eyes and read/write surface for read conveniently can be regulated to keep the distance be suitable for, and can work the desk frame with nearishtedness prevention put.
Background technology
In current known pre-myopia prevention device: it is double-U-shaped setting that buckle is arranged, complex structure, it is by the decorative pearl on top of an official cap setting that orbiting motion is located in decorative pearl on top of an official cap chute that location is arranged, complex structure.
Summary of the invention
In order to overcome in pre existing myopia prevention device, it is by the decorative pearl on top of an official cap deficiency that orbiting motion location is arranged in decorative pearl on top of an official cap chute that the double-U-shaped setting of buckle, location are arranged, the utility model provides a kind of desk frame with nearishtedness prevention, it not only simplify the labyrinth of double-U-shaped buckle, also simplify location setting is by the decorative pearl on top of an official cap labyrinth that orbiting motion location is arranged in decorative pearl on top of an official cap chute, energy correcting sitting postures, convenient eyes and the read/write surface for read of regulating keeps suitable distance, not needing to put this table frame with rising during this table frame, thus can also not affect other purposes of desktop.
The utility model solves its technical scheme: holding screw, U-shaped buckle, through connecting axle, the female bar of actuating rod, range adjuster, actuating rod sub bar, actuating rod crossbeam connects, U-shaped buckle arranges positioning convex point, U-shaped buckle and positioning convex point are the settings of one, the female bar of actuating rod arranges detent, the female bar of actuating rod and detent are the settings of one, detent is made to be inserted in the positioning convex point of desired location when rising and putting actuating rod, by the development length of range adjuster regulating action bar, leaning forward of health is blocked with actuating rod crossbeam, eyes and read/write surface for read is made to keep suitable distance to reach pre-myopic-preventing object.
The beneficial effects of the utility model are: when not needing by this table frame, when not removing this table frame, can rise and put this table frame, and do not affect other purposes of desktop, energy correcting sitting postures, the convenient distance regulating eyes and read/write surface for read to keep suitable, simplifies the labyrinth of double-U-shaped buckle, it is enough by the decorative pearl on top of an official cap labyrinth that orbiting motion location is arranged in decorative pearl on top of an official cap chute for simplifying location setting, and structure is simple.
