Description
Technical field
The utility model relates to a kind of study article, specifically a kind of myopia prevention writing backing plate.
Background technology
According to statistics, most of teen-age myopia are all relevant with incorrect writing posture, in recent years along with students in middle and primary schools' schoolwork burden increases the weight of gradually, the incidence of disease of myopia also is the trend that rises year by year, in order to help the teenager to keep correct writing posture, someone designs the product of some posture corrections, but this series products all is the health that supports the user with supporting structure mostly, or use traction belt traction after one's death the user, can feel not quite the thing after the long-term use of user, and be easy to generate dependence.
Summary of the invention
The purpose of this utility model provides a kind of myopia prevention writing backing plate, and it can be crossed apart from desktop at user's health and in time send caution when near, reminds the user to keep correct Writing distance, avoids forming myopia.
The utility model is achieved through the following technical solutions for achieving the above object: comprise backing plate, warning device is installed on the backing plate, the backing plate downside is provided with infrared sensing switch.The inner control circuit board of installing of warning device is installed control chip on the control circuit board, warning lamp is installed on the warning device surface, and the warning device side is provided with battery compartment.Warning device inside is equipped with motor, setting-up eccentricity oscillator on the output shaft of motor.Electronic clock is installed on the warning device surface.
Advantage of the present utility model is: reasonable in design, can cross apart from desktop at user's health and in time send caution when near, remind the user to keep correct Writing distance, avoid forming myopia, when the user does not in time change posture, send vibration prompt, help the user to eliminate fatigue.
