Description

Technical Field

[0001] This utility model relates to the field of vision rehabilitation training technology, and in particular to a training device for improving vision. Background Technology

[0002] Vision training devices are medical devices that train the eye muscles by exercising the ability of the eyeballs to rotate inward and outward. This involves constantly moving the visual axes of both eyes to train the three muscles that control vision—the ciliary muscle, extraocular muscles, and iris muscles. Through coordinated training, these muscles are relieved of paralysis and stiffness, making them stronger and more flexible. This improves the eye muscles' ability to adjust, ultimately achieving clear imaging of objects on the retina and restoring vision.

[0003] Vision rehabilitation training is mostly aimed at people with myopia. During training, trainees can observe moving objects and make their eyes follow the objects, while switching from near to far views to relieve eye fatigue and improve myopia symptoms. During training, it is necessary to adjust the observation position according to the trainee's eye condition to assist in rehabilitation training. Therefore, a vision-improving training device is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that the observation position needs to be adjusted according to the trainee's eye condition, and to propose a vision-improving training device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vision-improving training device includes a base, a guide plate and an internal tooth fixing plate fixedly connected to the upper surface of the base, a first frame and a second frame mounted above the guide plate, the surfaces of the first frame and the second frame being slidably connected, and an observation lens being fixedly connected to the inner walls of both the first frame and the second frame, and a training adjustment mechanism being mounted on the surface of the internal tooth fixing plate.

[0007] Preferably, the training adjustment mechanism includes a motor fixedly connected to the surface of the internal tooth fixing plate, the output end of the motor passing through the inner wall of the internal tooth fixing plate and fixedly connected to a first gear, a turntable rotatably connected to the inner wall of the internal tooth fixing plate, and a second gear rotatably connected to the surface of the turntable, the first gear meshing with the second gear, and the second gear meshing with the internal tooth fixing plate.

[0008] Furthermore, a training disc is rotatably connected to the surface of the second gear, and a friction ring plate is fixedly connected to the side of the internal tooth fixing disc near the guide plate. The surface of the training disc is in frictional contact with the surface of the friction ring plate, and multiple light-emitting lamps of different colors are installed on the inner wall of the training disc.

[0009] Preferably, a light-blocking ring plate is fixedly connected to the side of the internal tooth fixing plate near the guide plate, and a sliding plate is slidably connected to the inner wall of the guide plate, with the surface of the second frame slidably connected to the inner wall of the sliding plate.

[0010] Furthermore, the guide plate has clearance holes on its surface, a pair of gaskets are fixedly connected to the surface of the sliding plate, a threaded rod is fixedly connected to the surface of the sliding plate, and a threaded sleeve is threadedly connected to the surface of the threaded rod. The side of the threaded sleeve close to the sliding plate squeezes and rubs against the surface of the gasket.

[0011] Preferably, the upper surfaces of the second frame and the first frame are provided with multiple slots, one of which is connected to the inner wall of the sliding plate with the same positioning pin. The positioning pin is adapted to the slot, and a spring is sleeved on the surface of the positioning pin. One end of the spring is fixedly connected to the surface of the positioning pin, and the other end of the spring is fixedly connected to the surface of the sliding plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] The trainee can adjust the distance between a pair of observation mirrors to adapt to the training plate. By sliding the position of the sliding plate, the distance between the observation mirrors and the training plate can be adjusted, thus adjusting the near-field distance observed by the trainee. The second gear rotates around the center of the inner tooth fixed plate. When the training plate moves, it rotates around the center of the second gear, allowing the eyeballs to move flexibly while following the movement. After observing a light of a specified color through the observation mirrors for a certain period of time, the trainee looks into the distance to observe the scenery. Through the combination of near and far distances, the trainee's eyes undergo rehabilitation training. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A vision-improving training device includes a base 1. A guide plate 2 and an internal tooth fixing plate 6 are fixedly connected to the upper surface of the base 1. A first frame 4 and a second frame 3 are installed above the guide plate 2. The surfaces of the first frame 4 and the second frame 3 are slidably connected. Observation mirrors 5 are fixedly connected to the inner walls of the first frame 4 and the second frame 3. A training adjustment mechanism is installed on the surface of the internal tooth fixing plate 6.

[0021] By setting an internal tooth fixing plate 6, a motor 7 is fixedly installed. By setting an observation mirror 5, the trainee's eyes are protected. By setting a training adjustment mechanism, the distance between the observation mirror 5 and the training plate 13 can be adjusted. At the same time, the distance between a pair of observation mirrors 5 can be adjusted to better assist the trainee in viewing the light lamp 11 and carrying out rehabilitation training.

[0022] In this utility model, reference Figure 2 The training adjustment mechanism includes a motor 7 fixedly connected to the surface of the internal tooth fixing plate 6. The output end of the motor 7 passes through the inner wall of the internal tooth fixing plate 6 and is fixedly connected to a first gear 10. The inner wall of the internal tooth fixing plate 6 is rotatably connected to a turntable 8. The surface of the turntable 8 is rotatably connected to a second gear 9. The first gear 10 meshes with the second gear 9, and the second gear 9 meshes with the internal tooth fixing plate 6.

[0023] By setting motor 7, the first gear 10 is driven to rotate. By setting second gear 9, the rotation of the first gear 10 drives the second gear 9 to rotate. The second gear 9 cooperates with the inner wall of the internal tooth fixing plate 6, driving the turntable 8 to rotate together with the second gear 9.

[0024] In this utility model, reference Figure 2The training disc 13 is rotatably connected to the surface of the second gear 9. The friction ring plate 12 is fixedly connected to the side of the internal tooth fixing disc 6 near the guide plate 2. The surface of the training disc 13 is in frictional contact with the surface of the friction ring plate 12. Multiple lights 11 of different colors are installed on the inner wall of the training disc 13.

[0025] By setting up a training disc 13 and installing multiple LEDs 11 of different colors, and by setting up a friction ring plate 12 to make frictional contact with the surface of the training disc 13, the training disc 13 is driven to rotate.

[0026] In this utility model, reference Figure 2 and Figure 3 A light-blocking ring plate 14 is fixedly connected to the side of the internal tooth fixing plate 6 near the guide plate 2. A sliding plate 21 is slidably connected to the inner wall of the guide plate 2. The surface of the second frame 3 is slidably connected to the inner wall of the sliding plate 21.

[0027] By setting up a light-blocking plate 14, strong external light is prevented from affecting the trainee's observation. By setting up a sliding plate 21, the position of the first mirror frame 4 and the second mirror frame 3 can be adjusted and supported.

[0028] In this utility model, reference Figure 4 The guide plate 2 has a clearance hole 22 on its surface. A pair of gaskets 17 are fixedly connected to the surface of the sliding plate 21. A threaded rod 19 is fixedly connected to the surface of the sliding plate 21. A threaded sleeve 18 is threadedly connected to the surface of the threaded rod 19. The side of the threaded sleeve 18 close to the sliding plate 21 squeezes and rubs the surface of the gasket 17.

[0029] By setting the clearance hole 22, the movement of the threaded rod 19 is spatially cleared. By setting the threaded sleeve 18, which is threadedly connected to the surface of the threaded rod 19, the surface of the gasket 17 can be pressed and positioned.

[0030] In this utility model, reference Figure 3 The upper surfaces of the second frame 3 and the first frame 4 are provided with multiple slots 16. One of the slots 16 is connected to the inner wall of the sliding plate 21 with the same positioning pin 15. The positioning pin 15 is adapted to the slot 16. A spring 20 is sleeved on the surface of the positioning pin 15. One end of the spring 20 is fixedly connected to the surface of the positioning pin 15, and the other end of the spring 20 is fixedly connected to the surface of the sliding plate 21.

[0031] By setting a positioning pin 15, which is inserted into the slot 16, the position of the second frame 3 and the first frame 4 after sliding adjustment is kept stable. By setting a spring 20, the insertion of the positioning pin 15 is kept stable.

[0032] Working principle: Before use, adjust the distance between the pair of observation mirrors 5 according to the trainee's needs. Then, pull up the positioning pin 15, lengthening the spring 20 and releasing it from the slot 16. After adjusting the sliding position of the second mirror frame 3 and the first mirror frame 4, reinsert the positioning pin 15 into the corresponding slot 16 to maintain its position. Simultaneously, rotate the threaded sleeve 18. After the threaded sleeve 18 presses against the surface of the pad 17, slide to adjust the position of the sliding plate 21. Then, reverse the threaded sleeve 18 so that one end of the threaded sleeve 18 rubs against the surface of the pad 17, maintaining the position of the sliding plate 21. Once the positioning of 1 is stable, motor 7 is started. The output of motor 7 drives the first gear 10 to rotate, and the first gear 10 drives the second gear 9 to rotate. Under the action of the internal tooth fixing plate 6, the second gear 9 drives the turntable 8 and the second gear 9 to move as a whole. When the second gear 9 moves, the training plate 13 comes into contact with the surface of the friction ring plate 12, causing the training plate 13 to rotate. At this time, the trainee's eyes observe the light 11 of the specified color through the observation mirror 5 for a certain period of time, and then look into the distance to observe the scenery. Through the combination of near and far distances, the trainee's eyes undergo rehabilitation training.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
