Abstract
The utility model relates to a device for preventing myopia by means of correcting writing gesture, which comprises a rope, a rubber band, a rope fastener and an alarm device. The alarm device consists of a power source, a switch, an alarm component and an elastic contact switch, the rope, the rubber band and the alarm device form a rope sling, one end of the rope sling is nested on the neck of a user, the other end of the rope sling is nested on the wrist of the user, the rope fastener capable of adjusting the length of the rope is disposed on the rope, and the power source, the switch, the alarm component and the elastic contact switch in the alarm device form a closed circuit. When tension of the rope sling is small, the elastic contact switch can be conducted so that the alarm component operates, and exertion of the tension of the rope sling can be terminated when the tension reaches a certain degree. The contact switch is easier to stretch than the rubber band so as to guarantee that the contact switch cannot be conducted when the rubber band stretches. The device for preventing myopia is simple and reliable in structure, is made of materials which are common in markets, and is low in cost, small in volume and convenient in storage and carrying.
Description
Technical field
The utility model relates to a kind of by correcting the device of the pre-myopia prevention of writing posture, and particularly a kind of pre-myopia prevention writing posture that has warning function is corrected rope.
Background technology
Myopia has become puzzlement students in middle and primary schools' a major issue at present.The reason that causes students in middle and primary schools' hypometropia is many-sided, is the major reason that produces this problem with the eye hypotelorism.The writing posture that can force to keep correct by device, the furniture of some special uses and best with eye distance from, thereby play the effect of pre-myopia prevention.These devices can be divided into two big classes; one class is the frame class mechanism that is fixed on the desk; as " strong positive pupil reading and writing posture, pre-myopia prevention, protection vertebra normal development framework " (patent No.: 94240970.1), " correct faulty sitting posture, pre-myopia prevention learning board " (patent No.: 02203489.7).One class is the electronic installation of reporting to the police by sound, light, electro-detection distance or fault, as " myopia prevention prompt " (application number: 200710115909.1), " hypometropia prevention alarm " (application number: 200810048663.5) etc.
More than device or structure complicated, be not easy to carry, or manufacturing cost is higher, reliability is not high.
The utility model content
The purpose of this utility model provides a kind of device that is simple and easy to usefulness, help the student to keep correct writing posture, different prompt functions such as sound, light or vibrations are provided according to the varying environment of school, family when fault, and the use by certain hour reaches the purpose of progressively correcting writing posture, pre-myopia prevention.
The utility model provides a kind of pre-myopia prevention writing posture that has warning function to correct rope, comprises that rope, bungee, rope buckle and warning device, and warning device comprises power supply, switch, warning piece, elastic force contact switch; Wherein rope, bungee, warning device are formed rope sling, and rope sling one end is enclosed within on the neck, and the other end is enclosed within on the wrist, and rope is provided with the rope of scalable rope lengths and buckles; Power supply in the warning device, switch, warning piece, elastic force contact switch constitute closed circuit; When hour elastic force contact switch meeting conducting of rope sling tension force, make warning piece work, when acquiring a certain degree, rope sling tension force will disconnect; Contact switch is than the easier stretching of bungee, to guarantee that contact switch is not switched in the bungee elongation.
Use principle of the present utility model is: rope sling one end is enclosed within on the neck, the other end is enclosed within on the wrist, buckle the length that to regulate rope sling by rope, make neck and wrist remain on a rational distance, thereby guarantee to keep a rational distance between eyes and the pen, when the user attempt to increase trick apart from the time, can be subjected to the restriction of rope sling length, when the user attempt to reduce trick apart from the time, at first be that bungee shrinks, when distance surpassed a limit, alarm will be reported to the police, and reminded user's trick hypotelorism.The effect of bungee is that rope sling can be stretched within the specific limits, and its effect has two: the one, and allow arm movable in a scope, the 2nd, avoid warning device too responsive, have slightly just to shrink and report to the police.Warning device by sound at the same time or separately, light and alerting by vibration user hypotelorism, warning device reduces to trigger by cord tension.Warning device can comprise power supply, switch, warning piece such as hummer, vibrating motor, light emitting diode etc., elastic force contact switch etc.Power supply is system's power supply; Switch is to cut off system power supply when not using in system, also can use switch to select type of alarm simultaneously; The elastic force contact switch will disconnect when rope sling tension force acquires a certain degree, can conducting when tension force hour, make warning piece work, and contact switch is than the easier stretching of bungee, to guarantee that contact switch is not switched in the bungee elongation.
Beneficial effect
1, simple and reliable for structure, material therefor all is common article on the market, and is cheap.
2, device volume little, in light weight, be convenient to take in, be easy to carry.
3, easy to use, only need regulate rope sling length, open switch, can directly wear use.
4, provide type of alarms such as sound, light, vibrations according to tame school varying environment.
