Base plate is provided with the gap of a transverse direction, and the lower end of paper can be passed from this gap.
Press strip is also provided with at least one in sidepiece lock-screw (5) or rear end lock-screw (6).
Described inductor is arranged on the upper end of pillar, and described inductor is contact inductor or noncontact inductor, and described noncontact inductor comprises infrared inductor, ultrasonic sensing device or capacitive proximity sensor; Contact inductor is touching switch (such as capacitive touch-sensitive switch or inductance type contact-making switch).
False-touch prevention Power Generation Road is provided with between inductor and reminiscences.
Described myopia prevention device, is characterized in that, also comprise a sender unit for being connected with external unit (such as desk lamp), the input end of sender unit is connected with sensor output signal.Once report to the police, then pass through this sender unit output alarm signal to desk lamp, notice desk lamp is turned off the light.
The width range of press strip is 2-5cm.
The altitude range 5-25cm of pillar, also can 10-20cm, preferred 13-15cm.
The area of base plate is greater than the area of A4 paper, preferred 330X400mm.
Pillar can be used for holding the lower jaw of user, or for installing inductor, or for preventing student from lying prone at desk.
The effect of false-touch prevention Power Generation Road, when inductor triggers, after time delay a period of time (such as 10-15 second), if this trigger pip also exists, then start warning, false-touch prevention Power Generation Road is existing ripe circuit.
Reminiscences can adopt the mode such as sound, flashing light, vibrations to send prompting.
Gap can be offered on the base plate of middle monoblock; Or arrange one piece of connection strap in the front end of base plate in addition, form described gap between connection strap and base plate, connection strap and base plate are by links such as screws or be welded and fixed, and pillar is arranged on connection strap.
Beneficial effect:
Myopia prevention device of the present utility model, because pillar is by press strip directly fixing middle base plate, therefore, regardless of the desk of what shape, as long as in base plate being spread on desktop, then pillar just can be fixed, and versatility is good.In addition, owing to adopting a pillar, size can be done wider, and therefore, physical strength is very high.And structure is very simple on the whole, install and regulate highly convenient, easy to implement.Myopia prevention device of the present utility model also has many human oriented designs, as being provided with plate edge, gap, cushion pad, sidepiece lock-screw, reminiscences, inductor and rear end lock-screw etc., therefore this myopia prevention device feature richness, is applicable to students in middle and primary schools and uses very much.
