[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a foldable ophthalmic vision training flip mirror, including a connecting rod 1. A sliding block 2 is slidably connected to the outside of the connecting rod 1. The connecting rod 1 provides a sliding track for the sliding block 2, ensuring that the sliding block 2 can be stably adjusted on its outside. Two L-shaped blocks 3 are slidably connected inside the sliding block 2. The sliding block 2 can change its position on the connecting rod 1, thereby adjusting the overall spacing of the flip mirror. A rotating column 4 is fixedly connected inside each of the L-shaped blocks 3, realizing the rotational connection between the L-shaped blocks 3 and the sliding block 2, so that the L-shaped blocks 3 can rotate around the rotating column 4 inside the sliding block 2. The rotating column 4 is slidably connected to the inside of the sliding block 2. The rotating column 4 ensures the stability and flexibility of the rotation of the L-shaped blocks 3, so that the L-shaped blocks 3 will not shake or jam during rotation, ensuring the smooth operation of the adjustment components. A pressure plate 5 is slidably connected to each adjacent side of the L-shaped blocks 3. The pressure plate 5 slides inside the sliding block 2 under the drive of the L-shaped blocks 3, and applies pressure to components such as the spring 8 through interaction with other components.
[0034] The two pressure plates 5 are externally slidably connected to the inside of the sliding block 2. The outside of the two stops 9 is in contact with the inside of the connecting rod 1. The stops 9 prevent the sliding block 2 from sliding excessively and disengaging from the connecting rod 1 during adjustment. Support columns 7 are fixedly connected to adjacent sides of the pressure plates 5. The support columns 7 provide support and guidance for the pressure plates 5, ensuring that the pressure plates 5 can move in a straight line during sliding, improving the adjustment accuracy and stability of the adjustment assembly. Two slots 10 are opened inside the sliding block 2. The slots 10 ensure that components such as the spring 8 can extend, retract, and slide within a specified range, making the adjustment process of the adjustment assembly more standardized and stable. The outside of the two support columns 7 is sleeved inside the spring 8. Under the action of the pressure plates 5, the spring 8 is compressed or stretched, storing and releasing energy to provide restoring force and buffering force for the adjustment assembly. Each support column 7 has a baffle 6 fixedly connected to its exterior. The baffle 6 is fixed to the support column 7 to limit the position of the spring 8 and prevent the spring 8 from shifting or disengaging during the extension and retraction process. Each of the two support columns 7 has another baffle 6 slidably connected to its exterior. Each baffle 6 has a spring 8 fixedly connected to its adjacent side. Each support column 7 has a stop block 9 fixedly connected to its adjacent side. Each connecting rod 1 has a fixing block 13 fixedly connected to its exterior. The fixing block 13 stably installs the support frame 11 on the connecting rod 1, ensuring a stable positional relationship between the lens 12 and the adjustment component. Each sliding block 2 has two support frames 11 fixedly connected to its distant side. The support frames 11, through connection with the fixing block 13 and other components, stably install the lens 12 on the flip mirror. The fixing block 13 has a component fixedly connected to its exterior for quick replacement.
[0035] Reference Figure 4 , Figure 5 The replacement component includes multiple support frames 11, with two other support frames 11 fixedly connected to the outside of a fixing block 13 on their adjacent sides. The support frame 11 is the core component for the vision training function of the flip mirror. By switching between lenses 12 of different powers, the eyes are trained to adjust. Each support frame 11 is internally threaded with a lead screw 15, and the top of each lead screw 15 is fixedly connected with a rotating handle 14. The rotating handle 14 provides a convenient operating component for the user, allowing the user to easily control the rotation of the lead screw 15. Multiple rotating plates 16 are externally slidably connected to the inside of the support frame 11. The rotating plates 16 clamp and release the lens 12, ensuring that the lens 12 will not loosen during use and can be easily disassembled during replacement. The inside of the support frame 11 is in contact with the outside of the lens 12. The bottom of each lead screw 15 is fixedly connected with a rotating plate 16. By rotating the lead screw 15, the lead screw 15 can move up and down inside the support frame 11.
[0036] Each rotating plate 16 has a connecting rod 17 fixedly connected to its right side. The connecting rod 17 slides inside the support frame 11, providing guidance and support for the sliding of the rotating plate 16, ensuring that the rotating plate 16 can move in a straight line during sliding. Multiple connecting rods 17 are externally slidably connected to the inside of the support frame 11. Each support frame 11 has a slot 20 inside, ensuring that these components slide within a specified range, making the fixing and replacement of the lens 12 more standardized and stable. A fixing handle 21 is fixedly connected to the right side of the connecting rod 1, providing a handhold for the user to easily grip and operate the rotating mirror. Each rotating plate 16 has a connecting rod 17 fixedly connected to its left side. Connecting rod 2 18 ensures the coordinated work between various components during the movement of rotating plate 16, making the fixing and replacement of lens 12 smoother. Each connecting rod 2 18 has a fixed rod 19 fixedly connected inside. The fixed rod 19 provides rotational support for connecting rod 1 17 and connecting rod 2 18, allowing rotating plate 16 to rotate and slide flexibly during movement. Each connecting rod 1 17 has another fixed rod 19 fixedly connected inside. The external parts of multiple fixed rods 19 are rotatably connected to the inside of support frame 11. The fixed rods 19 allow rotating plate 16 to rotate and slide flexibly during movement, ensuring the normal operation of replacement components. The adjacent sides of rotating handle 14 are in contact with the outside of support frame 11.
[0037] Working principle: Connecting rod 1 provides a sliding track for sliding block 2. The overall spacing is adjusted by sliding block 2 on connecting rod 1. L-shaped block 3 rotates inside sliding block 2 through rotating column 4, driving pressure plate 5 to slide. Pressure plate 5 compresses spring 8 and deforms it, generating restoring force and buffering force. Support column 7 ensures that pressure plate 5 slides linearly. Baffle 6 restricts the position of spring 8. Baffle 9 prevents sliding block 2 from sliding out excessively, thus meeting different vision training needs. The flip mirror can be adjusted to a suitable angle according to the patient's sitting or lying posture or different training environment to ensure that the patient can perform vision training in a comfortable state, improving training compliance. By adjusting the angle, the patient's eyes can maintain the best visual angle with lens 12, allowing training light to enter the eyes at a suitable angle, simulating different visual scenarios, and more specifically exercising eye muscles to improve the vision training effect.
[0038] The support frame 11 fixes the lens 12, and the fixing block 13 connects it to the connecting rod 1. The user rotates the handle 14, which drives the lead screw 15 to rotate inside the support frame 11. The rotating plate 16 at the bottom of the lead screw 15 moves accordingly. The first connecting rod 17 and the second connecting rod 18 are restricted in their movement trajectory under the support of the fixing rod 19. With the help of the rotating plate 16 sliding along the support frame 11, the lens 12 can be clamped or released. The second slot 20 limits the sliding of each component to ensure standardized and stable operation. Ultimately, the lens 12 can be replaced quickly and stably to meet different vision training needs. At the same time, there is no need to replace the entire flip lens due to problems with the lens 12, thereby extending the overall service life of the device and reducing the cost of use. For patients who need to use multiple lenses 12 for alternating training, the quick replacement function allows them to easily switch lenses 12 in different scenarios and training needs.
