Abstract
The utility model provides a correct posture keeper for teenagers, belonging to a protecting and treating device. When the teenagers are in unusual postures over 2 to 10 seconds, the correct posture keeper sends out a warning to remind the teenagers to change the unusual postures. After a correct posture is adopted, the correct posture keeper stops warning. Therefore, the teenagers' nearsightedness and hunchback are prevented. Moreover, the posture keeper has the functions of rectification and treatment. The utility model has the advantages of small size, low cost and convenient operation. The utility model is popular among the teenagers and the teenagers' parents.
Description
Teenager correct status keeper belongs to the protection therapy equipment.
Teenager is in growth promoter period, and unusual body appearance not only makes skeleton development unusual, forms bow-backedly, and damages teen-age vision, forms myopia etc.Still there is not at present a kind of apparatus that keeps the teenager correct status effectively.
This utility model is for teenager keeps correct status, a kind of novel electron apparatus that the tender positive myopia of prevention provides with hunchback.It can be in abnormal posture and surpass 2-10 during second at teenager, gives the alarm, and reminds it to change abnormal posture.After taking correct status, stop alarm.
This utility model is achieved in that it is made up of device box, sensing body.The 1.5V5 battery that one delayed alarm circuit, a speaker and a joint are used as dc source is housed in the device box (1).Accompanying drawing 3 is teenager correct status keeper circuit diagrams, and it comprises delay circuit and warning circuit two parts.Delay circuit is by audion (BG
3), electric capacity (C
4), sensing body switch (K
2), adjustable resistance (R
6) and resistance (R
7) and (R
8) form.Tuning (R
6) can change delay time.Warning circuit is made up of an astatic multivibrator and a resistance-capacitance coupling amplifier stage.Delayed alarm circuit can be in abnormal posture and surpass 2-10 and give the alarm during second at teenager, can not report to the police when the croucs that takes place in moment moves.This utility model is specially adapted to teenager and bends over the desk alone study or when work in family's long period.In public, influence other people for not making chimes of doom, the design chimes of doom makes the user that is in abnormal posture only oneself just can hear chimes of doom by weak crescendo, just can change abnormal posture, takes correct status.In addition, earphone jack (4) also is equipped with in device box (1) outside, and behind the insertion earplug, speaker opens circuit.The astatic multivibrator frequency of oscillation is 300-600HZ.Device box (1) one side is equipped with on and off switch (2), sensing body jack (3) and earphone jack (4), and there is porous (5) in device box (1) front, pronounces in order to speaker.The signal that the sensing body is sent here is imported by sensing body jack (3).
This utility model not only can prevent juvenile myopia and bow-backed generation, and also has tender positive therapeutical effect, for forming pseudomyopia and slight bow-backed teenager, can get well as long as adhere to using.This utility model has been subjected to the teenager and the head of a family's thereof welcome.
When using this utility model, the sensing body is hung on collar rear portion central authorities, make reed (8) towards napex, device box (1) can be packed in the coat pocket, sensing body plug (12) is injected the sensing body jack (3) of device box (1), start on and off switch (2) and promptly start working, after finishing using, powered-down.
Accompanying drawing 1 is a teenager correct status keeper device box outline drawing.
Accompanying drawing 2 is teenager correct status keeper sensing body structure figure.
Accompanying drawing 3 is teenager correct status keeper circuit diagrams.
In the accompanying drawing 1,2,3: 1 is the device box, and 2 is on and off switch, and 3 is sensing body jack, and 4 is earphone jack, and 5 is sound hole, and 6 is base plate, and 7 is stationary contact, and 8 is reed, and 9 is movable contact, and 10 are hook, and 11 is lead, and 12 is plug, BG
