Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and more specifically, it relates to a device for fine-tuning the distance of the eyepiece lens of a visual rehabilitation training instrument. Background Technology

[0002] A visual rehabilitation training device is a machine that trains the eye muscles and exercises the visual axes of both eyes to restore vision. This device can alleviate eye muscle paralysis and stiffness, restoring the eye muscles to a strong and flexible state, thereby improving their ability. During use, it trains the eye muscles by training their inward and outward rotation, and the continuous movement of both eyes trains the ciliary muscle, extraocular muscles, and iris muscle, which are responsible for vision. Through coordinated training, it addresses and alleviates symptoms of eye muscle stiffness and paralysis, thereby improving eye muscle coordination and ultimately achieving clear imaging of objects on the retina. The basic structure of the visual rehabilitation training device includes a visual stimulation device, a control system, and an interactive interface. The training content mainly includes visual perception training, visual tracking training, visual positioning training, visual attention training, and visual response training. These training methods are crucial to the effectiveness of visual rehabilitation.

[0003] The distance between the two sets of eyepieces in existing training devices is usually fixed, making it difficult to adjust the distance according to the interocular distance of the user. This results in poor training effectiveness and low comfort, limiting its practical use. Therefore, this paper researches and improves upon the existing structure and its shortcomings, providing a fine-tuning device for the eyepiece distance of a visual rehabilitation training device, aiming to achieve greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a device for fine-tuning the distance of the eyepiece lens of a visual rehabilitation training instrument, which is achieved by the following specific technical means:

[0005] A fine-tuning device for the distance of an eyepiece lens in a visual rehabilitation training instrument includes a support. Two sets of eyepiece frames for fixing the eyepiece are mounted on the support. Two sets of upright plates are fixedly mounted on both the left and right ends of one side of the support. A rear guide rod and a front guide rod are fixedly mounted between the two sets of upright plates. Two sets of upper moving blocks are symmetrically slidably connected to the outer sides of the rear guide rod and the front guide rod. One side of each set of upper moving blocks is fixedly connected to one side of the two sets of eyepiece frames.

[0006] Furthermore, two sets of support seats are symmetrically connected to the outer middle of the rear guide rod and the front guide rod. One side of each set of support seats is fixedly connected to one side of the support. Both sets of support seats and the adjacent upright plate are rotatably connected to a lead screw through a bearing.

[0007] Furthermore, each of the lead screws is fitted with a ball screw nut on its outer side, and the outer sides of the two sets of ball screw nuts are respectively fixedly connected to the inner sides of the two sets of upper moving blocks.

[0008] Furthermore, an upper support is fixedly installed on one side of both sets of support seats, and a main shaft that can be connected to a motor is rotatably connected to the middle of the upper support seat via a bearing.

[0009] Furthermore, the bottom end of the main shaft passes through the upper support and is fixedly installed with a main gear. One end of each of the two sets of lead screws is located between the two sets of support seats and is fixedly installed with a driven gear. Both sets of driven gears are meshed with the main gear.

[0010] Furthermore, a lower moving block is fixedly installed on the other side of each of the two sets of eyepiece frames, and a guide bearing is fixedly installed on the inner side of each of the two sets of lower moving blocks. A lower guide rod is connected to the inner side of each of the two sets of guide bearings.

[0011] Furthermore, locking blocks are fixedly installed on the outer sides of both ends of the lower guide rod, and one side of each set of locking blocks is fixedly connected to one side of the support.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention utilizes a lead screw, a front guide rod, and a rear guide rod to enable flexible movement of the upper moving block. The coordination between the upper and lower moving blocks allows for stable movement of the eyepiece frame. This enables flexible adjustment of the distance between the two eyepiece frames based on the user's interocular distance, allowing the eyepieces on both frames to better fit the user's left and right eyes, thereby improving the training effect and user comfort.

[0014] This invention, through the cooperation of the upper support and the main shaft, enables the flexible movement of the main gear. Through the cooperation of the main gear and the driven gear, it enables the flexible rotation of two sets of lead screws by rotating the main shaft, and simultaneously drives the flexible movement of two sets of eyepiece frames, increasing the convenience of adjusting the distance between the eyepiece frames.
