Abstract
The utility model discloses a myopic prevention siren. The myopic prevention siren consists of a box body, a connection device which is used to fix the box body onto the rim of a table, an electronic sounding device which is arranged in the box body, and a movable sight distance gauge stick that triggers the electronic sounding device to sound the siren; wherein, the sight distance gauge stick includes a first end that triggers the electronic sounding device to sound the siren and a second end which is used to hold against the chin of a user, wherein, the first end of the sight distance gauge stick is arranged in the box body; and the second end of the sight distance gauge stick extends outside the box body; through the prompt of the siren, the students can be reminded of keeping appropriate sight distance and seating position, thereby preventing the occurrence of becoming short sighted and worsening eyesight.
Description
Technical field
Keep the articles for use of sighting distance when the utility model relates to a kind of writing, relate in particular to a kind of alarm that is used for pre-myopia prevention.
Background technology
At present, the myopia incidence of disease is higher, and the trend that rejuvenation is arranged, all like when mainly being student's reading and writing lying prone on desk, often face is placed on the desktop, eyes are too near from the books distance, abnormal sitting posture is true, time has been grown the eyes and the skeletal growth that influence the student and has grown, become the scholar of the curved back of the body camel of myopia and waist, at this problem, a lot of people have invented some therapeutic instrument for shortsightedness and prevention instrument, but result of treatment is little, teen-age near-sighted problem should be to put prevention first, and sighting distance excessively closely is the primary factor of myopia morbidity, so the sighting distance of control student when study allows the student keep a better learning custom just to become to solve the key of near-sighted problem.
The utility model content
Technical problem to be solved in the utility model provides a kind of student of allowing can keep sighting distance when study the alarm that is used for pre-myopia prevention.
For solving the problems of the technologies described above, the technical solution of the utility model is: the alarm that is used for pre-myopia prevention, comprise box body, be used for described box body is fixed in table along last coupling arrangement, be arranged at the electronic sound-producing device of described box body inside, trigger the movably sighting distance feeler that described electronic sound-producing device sends chimes of doom, described sighting distance feeler comprises and is used to trigger second end that electronic sound-producing device sends first end of chimes of doom and is used to lean user's lower jaw portion, first end of described sighting distance feeler is positioned at box body inside, and second end of described sighting distance feeler stretches out the box body outside.
As a kind of improvement, described electronic sound-producing device comprises loudspeaker, the surface-mounted integrated circuit that is connected with described loudspeaker, the switch that is connected with described surface-mounted integrated circuit.
As further improvement, described electronic sound-producing device also comprises the earphone that is connected with the output terminal of described surface-mounted integrated circuit.
Adopted technique scheme, the beneficial effects of the utility model are: the alarm that is used for pre-myopia prevention, comprise box body, be used for described box body is fixed in table along last coupling arrangement, be arranged at the electronic sound-producing device of described box body inside, trigger the movably sighting distance feeler that described electronic sound-producing device sends chimes of doom, described sighting distance feeler comprises and is used to trigger second end that electronic sound-producing device sends first end of chimes of doom and is used to lean user's lower jaw portion, first end of described sighting distance feeler is positioned at box body inside, and second end of described sighting distance feeler stretches out the box body outside; The student is when study, when the distance of user's eyes and books narrow down to certain apart from the time, second end of sighting distance feeler will be run into by user's lower jaw portion, the sighting distance feeler passes to the action of the first end trigger switch with this pressing force, loudspeaker will ring, and can play good suggesting effect, and the prompting learner will keep a correct learning posture, keep certain sighting distance, and then play the effect of pre-myopia prevention.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
Embodiment
The alarm that is used for pre-myopia prevention, as shown in drawings, comprise box body 1, be used for box body 1 is fixed in table along last coupling arrangement, be arranged at the electronic sound-producing device of box body 1 inside, trigger the movably sighting distance feeler 3 that electronic sound-producing device sends chimes of doom, sighting distance feeler 3 comprises and is used to trigger second end that electronic sound-producing device sends first end of chimes of doom and is used to lean user's lower jaw portion, first end of sighting distance feeler 3 is positioned at box body 1 inside, and second end of sighting distance feeler 3 stretches out box body 1 outside.
Electronic sound-producing device comprises loudspeaker 6, the surface-mounted integrated circuit 5 that is connected with loudspeaker 6, the switch 4 that is connected with surface-mounted integrated circuit 5; Electronic sound-producing device also comprises the earphone 7 that is connected with the output terminal of surface-mounted integrated circuit 5.
Coupling arrangement comprises that being fixed in box body 1 bottom is used for and an open stand 8 that the edge matches, and is used for open stand 8 is fixed in the bolt 9 on an edge.
Sighting distance feeler 3 is made of expansion link, and the outside that sighting distance feeler 3 is positioned at second end of box body 1 outside is equipped with guard bar pipe 2, play the guiding role.
Principle of work: at first, with the bolt on the open stand 89 alarm is fixed on an edge, user's sighting distance is during less than predetermined distance, second end of sighting distance feeler 3 will be run into by its lower jaw portion, thereby make the first end push switch 4 of sighting distance feeler 3, make loudspeaker 6 send chimes of doom, thereby produce suggesting effect.
The output terminal of surface-mounted integrated circuit 5 also is connected with earphone 7, can be placed on earphone 7 on the ear, thereby reach the study that neither can influence other people, can produce the purpose of alarm effect again.
Sighting distance feeler 3 is made of expansion link, is convenient to adjust the sighting distance of regulation.
