Description

Technical Field

[0001] The present invention belongs to the technical field of vision training, and particularly relates to a training device and method for preventing myopia. Background Art

[0002] There are many causes of myopia, including: eye - using habits and looking at electronic products, etc. These causes of myopia are all due to the eyes not moving for a long time and not getting enough oxygen for aerobic exercise. It is possible to supplement sufficient oxygen by exercising the eye muscles and making the eyes move more, so as to achieve the purpose of improving and preventing myopia.

[0003] The training device for preventing myopia exercises the eye muscles by training the ability of the eyeball to rotate inside and outside, and makes the visual axes of both eyes move continuously to train three muscles that dominate vision: the ciliary muscle, the lens, and the medial rectus muscle.

[0004] The existing devices have problems in use; when traditional devices train users, the users need to fix their eyes on a moving object and directly rotate the eyeballs to conduct vision training. However, the amplitude and frequency of eyeball rotation are fixed and limited, resulting in the user's eyeballs may not be fully exercised, and the training efficiency is not high. Moreover, there is no reasonable training method. Therefore, we propose a training device and method for preventing myopia. Summary of the Invention

[0005] The purpose of the present invention is to provide a training device for preventing myopia. Through a training mechanism and a wearing mechanism, it solves the problem that when traditional devices train users, the users need to fix their eyes on a moving object and directly rotate the eyeballs to conduct vision training, but the amplitude and frequency of eyeball rotation are fixed and limited, resulting in the user's eyeballs may not be fully exercised and the training efficiency is not high. At the same time, a training method designed for this training device is proposed.

[0006] To solve the above - mentioned technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention is a training device for preventing myopia, including a training box. The outer wall of the training box is fixedly connected with a lens frame, and the inner wall of the lens frame is fixedly connected with a plurality of lenses. The inner wall of the training box is provided with a training mechanism.

[0008] The training mechanism includes a motor, the outer wall of the motor is fixedly connected to the inner wall of the training box, the bottom output shaft of the motor is fixedly connected to a transmission rod through a coupling, an inclined cam is fixedly connected to the outer wall of the transmission rod, several sliding sleeves are fixedly connected to the inner wall of the training box, a sliding rod is slidably connected to the inner wall of the sliding sleeve, several roller frames are fixedly connected to the outer wall of the sliding rod, rollers are rotatably connected to the outer walls of several roller frames, the outer wall of the roller is slidably connected to the outer wall of the inclined cam, and a fixing frame is fixedly connected to the outer wall of the sliding rod.

[0009] Further, an infrared emitter is fixedly connected to the inner wall of the fixing frame, and a display board is fixedly connected to the inner wall of the training box at one end away from the lens frame.

[0010] Further, a wearing mechanism is arranged on the top outer wall of the training box, and the wearing mechanism includes several worm seats, and worms are rotatably connected to the inner walls of several worm seats.

[0011] Further, a knob is fixedly connected to the outer wall of the worm, and a slide rail frame is fixedly connected to the top outer wall of the lens frame.

[0012] Further, several slide rail grooves are formed in the inner wall of the slide rail frame, and clip frames are slidably connected to the inner walls of several slide rail grooves.

[0013] Further, a connecting shaft plate is rotatably connected to the outer wall of the slide rail frame, and a connecting rod is fixedly connected to the outer wall of the connecting shaft plate.

[0014] Further, a worm gear is fixedly connected to the outer wall of the connecting rod at one end away from the connecting shaft plate, and the outer wall of the worm gear is meshed with the outer wall of the worm.

[0015] Further, several connecting shafts are rotatably connected to the outer wall of the connecting shaft plate, and the inner walls of several connecting shafts at one end away from the connecting shaft plate are rotatably connected to the outer wall of the clip frame.

[0016] Further, a training method for preventing myopia is that the eyes of the trainer follow the infrared points emitted by the infrared emitter and display on the display board to rotate up and down and left and right, rather than chasing the infrared points by rotating the head, so as to achieve the purpose of training the eyes. Train for 1-2 minutes in this way. After the training is completed, use a hot compress towel or rub the palms of both hands to make them hot, and stick the palms on the eyeballs for 5-7 seconds. Continuously train 5-7 times as a group, and keep it every day to achieve the purpose of preventing and restoring myopia.

[0017] The present invention has the following beneficial effects:

[0018] 1. In the present invention, an inclined cam is provided. The transmission rod drives the inclined cam to rotate. When the inclined cam rotates, it drives a plurality of rollers to reciprocate back and forth. Each of the plurality of rollers drives the roller frame to displace, the plurality of roller frames drive the sliding rod to displace, the sliding rod drives the fixed frame to displace, and the fixed frame slowly drives the infrared emitter to displace left and right back and forth. Then, the infrared emitter is started, so that the light spot displayed on the display board irradiated by the infrared emitter can be continuously displaced back and forth, prompting the user's eyes to rotate repeatedly at a high intensity when gazing at the light spot for vision training, ensuring that the user's eyes are fully exercised and improving the training efficiency.

[0019] 2. In the present invention, a clamping frame is provided. If it is necessary to reduce the distance between a plurality of clamping frames, the knob can be rotated clockwise. The knob drives the worm to rotate, the worm drives the worm wheel to rotate, the worm wheel drives the connecting rod to rotate, the connecting rod drives the coupling plate to rotate, the coupling plate drives one end of a plurality of coupling rods to rotate around it, and each of the plurality of coupling rods drives the clamping frames to approach each other to reduce the size of the wearable device, achieving the effect that the distance between a plurality of clamping frames can be freely adjusted to adapt to the head sizes of different users for stable wearing, preventing the device from being easily detached from the user's head due to external forces caused by differences in wearing sizes.

[0020] 3. The training method disclosed in the present invention, by using the training device in combination with the training method, can achieve the effects of preventing and improving myopia.

[0021] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A specific application of this embodiment is as follows:

[0037] When the staff needs to use the device, the motor 201 can be started. The motor 201 drives the transmission rod 202 to rotate. The transmission rod 202 drives the inclined cam 203 to rotate. When the inclined cam 203 rotates, it will drive a plurality of rollers 207 to reciprocate back and forth. The plurality of rollers 207 all drive the roller frame 206 to displace. The plurality of roller frames 206 drive the sliding rod 205 to displace. The sliding rod 205 drives the fixed frame 208 to displace. The fixed frame 208 slowly drives the infrared emitter 209 to displace left and right back and forth. Then, the infrared emitter 209 is started. The infrared emitter 209 will emit light onto the surface of the display board 210, making red light spots appear on its surface. The light spots will slowly perform left and right reciprocating displacement along with the infrared emitter 209. The user can perform vision training by gazing at the light spots and rotating the eyeballs as the light spots move. When wearing the device, the user's head needs to be placed between the plurality of clip frames 306 to fix the device, and both eyes should be directly facing the plurality of lenses 102 respectively. Observe the movement of the light spots through the lenses 102. If it is necessary to reduce the distance between the plurality of clip frames 306, the knob 303 can be rotated clockwise. The knob 303 drives the worm 302 to rotate. The worm 302 drives the worm gear 309 to rotate. The worm gear 309 drives the connecting rod 308 to rotate. The connecting rod 308 drives the connecting shaft plate 307 to rotate. The connecting shaft plate 307 drives one ends of the plurality of connecting shaft rods 310 to rotate around it. The plurality of connecting shaft rods 310 all drive the clip frames 306 to approach each other to reduce the size of the wearable device.

[0038] The present invention also discloses a training method for preventing myopia. When wearing the device, the user's head needs to be placed between several clamping frames 306 to fix the device. The trainer's eyes follow the infrared points emitted by the infrared emission head on the display board and rotate up and down and left and right, rather than chasing the infrared points by rotating the head, so as to achieve the purpose of training the eyes. Train for 1-2 minutes in this way. After the training is completed, use a hot compress towel or rub the palms of both hands to make them warm, then stick the palms on the eyeballs for 5-7 seconds. Continuously train 5-7 times as a group, and keep it up every day to achieve the purpose of preventing and restoring myopia.

[0039] Taking the students I trained as an example, around October 2024, a vision screening was carried out in XXX No. 3 Primary School where I work. I met a third-grade student who used to like watching mobile phone videos and suffered from myopia caused by frequent use of electronic products. Her eyes were nearsighted by about 300 degrees. After using the training device of the present invention combined with its training method for 7 months, her vision returned to normal.

[0040] Taking classmate Zhang in primary school as an example, his vision was detected to be about 220 degrees. Through the example of the previous classmate, he found me and trained through the device and method invented by me. After one month, his naked eye vision improved by 2 lines.

[0041] Through actual verification, the device and invention of the present invention have obvious effects on preventing and improving myopia.
