Embodiment 1

[0034] see Figure 1-5 , an automatic training device for preventing myopia for teenagers, comprising a casing 20 and a through hole 22 provided on the casing 20, the casing 20 is provided with a head-mounted design, and the casing 20 can be fixed on the head of the teenager through an elastic band, A battery 19 is installed inside the casing 20, and the battery 19 provides electric energy to the device. The inner cavity of the casing 20 is provided with a lens frame 3 and the lens frame 3 is embedded with a lens group for adjusting eyesight, and the lens group includes a positive mirror-9 , negative mirror one 10, positive mirror two 11 and negative mirror two 12, positive mirror one 9 and negative mirror one 10 train the user's right eye, positive mirror two 11 and negative mirror two 12 train the user's left eye Training, the motor 1 is fixed on the inner wall of the casing 20 and the output shaft of the motor 1 is fixed with a gear 2, and the gear 2 and the lens frame 3 ar...

Embodiment 2

[0036] Repeat Example 1, see Figure 4 , the lens frame 3 runs through a metal guide rail 1 4 and a metal guide rail 2 13, and the metal guide rail 1 4 and the metal guide rail 2 13 are all fixed on the inner wall of the casing 20, and the metal guide rail 1 4 and the metal guide rail 2 13 carry out the lens frame 3 The position is limited so that the lens holder 3 can only move in the horizontal direction, which improves the stability of the device.

Embodiment 3

[0038] Repeat Example 1, see figure 1 and Figure 5 , the output end of the main switch button 16 is electrically connected with the input ends of the display screen 8, button one 6, button two 18, limit switch one 7 and limit switch two 14 respectively, button one 6, button two 18, limit switch The output ends of the switch one 7 and the limit switch two 14 are electrically connected with the input end of the motor 1 .

[0039] Working principle: The device is divided into two modes: automatic training and manual training;

[0040] Automatic training:

[0041] Press the main switch button 16, the power indicator green light is always on (indicating that the power is on), press the button 2 18, the motor 1 starts to rotate, and because the gear 2 is meshed with the lens frame 3, the lens frame 3 moves to the direction of the limit switch 2 14 , it will stop when it touches the limit switch 2 14, and after the set time, the motor 1 will reverse, and it will stop when it touc...

Abstract

The invention discloses an automatic training instrument for preventing short-sighted of teenagers. The automatic training instrument comprises a machine housing and a through hole formed in the machine housing, wherein a lens frame is arranged in an inner cavity of the machine housing; a lens set for adjusting vision is embedded on the lens frame; a motor is fixed to the inner wall of the machinehousing; a gear is fixed to an output shaft of the motor; and a control circuit board and a main circuit board are fixed to the inner walls of two sides of the machine housing through brackets. According to the automatic training instrument disclosed by the invention, the machine housing adopts head wearing design, and can be fixed to the head of a teenager through an elastic band; a button II, aspacing switch I, a spacing switch II and a main circuit board are arranged, so that continuous positive and negative rotation can be performed by the motor; a gear is in meshing connection with thelens frame, so that the lens frame drives the lens set( two sets of concave and convex lenses and convex and convex lenses, of different degrees) to make reciprocating movement in the horizontal direction to enable two eyes to view front objects through the concave and convex lenses and the convex and convex lenses according to different frequency conversion, so that the human eyes can view the front object according to different frequency conversion focal distance, the shifting training of automatically viewing objects in far and near of the teenager is realized, and the more comfort, safer,and more convenient experience feeling can be provided for the teenagers.

Description

technical field [0001] The invention relates to the technical field of automatic training instruments, in particular to an automatic training instrument for preventing myopia in adolescents. Background technique [0002] In the state of adjustment and relaxation, parallel light rays are focused in front of the retina after passing through the eyeball refractive system, which is called myopia. Myopia is also called short-sightedness, because this kind of eye can only see near but not far. After being refracted by the refractive system of the eye, the parallel light from infinity gathers into a focal point in front of the retina, and then forms an unclear image on the retina. The distance vision is obviously reduced, but the near vision is still normal. [0003] The automatic training device for the prevention of myopia in young people is an automatic vision training and recovery equipment for young people based on Bates' theory. At present, there are manual training equipment...
