[0024] In the specific implementation process, such as Figures 1-5As shown, an ophthalmic fundus camera includes a base plate 1, which supports the entire device and serves as a fixed foundation for other components. A groove is formed at one end of the base plate 1, and a threaded rod 2 is installed within the groove. A telescopic frame 3 is threadedly connected to the threaded rod 2. The telescopic frame 3 adapts to the groove. Rotation of the threaded rod 2 within the groove drives the telescopic frame 3 to move along the groove direction, thereby adjusting the position of the imaging device. A displacement frame 4 is fixedly connected to the top surface of the telescopic frame 3. A displacement rod 5 is installed within the displacement frame 4. Grooves are formed on both sides of the bottom end of the displacement rod 5, and a first elastic element 6 is installed within the grooves. Multiple grooves adapted to the first elastic element 6 are formed on the inner sidewall of the displacement frame 4. The imaging device is mounted on the top of the displacement rod 5. The movement of the displacement rod 5 within the displacement frame 4... The first elastic element 6 is used to achieve fine adjustment and stability of the imaging device in the horizontal direction. A rotating ring 8 is fixedly connected to the end of the base plate 1 without a sliding groove. A rotating plate 9 is rotatably connected to the inner side of the rotating ring 8. Multiple grooves are formed on the outer side of the rotating plate 9, and a second elastic element 7 is installed in the grooves of the rotating plate 9. Multiple grooves adapted to the second elastic element 7 are formed on the inner wall of the rotating ring 8. Rotation of the rotating plate 9 allows for a wide range of rotational adjustments of the imaging device in the horizontal direction. A threaded post 10 is fixedly connected to the top surface of the rotating plate 9. A threaded sleeve 11 is threadedly connected to the external thread of the threaded post 10. A support frame 12 is fixedly fitted onto the external threaded sleeve 11. By rotating the threaded sleeve 11, the height of the support frame 12 is adjusted, thereby adjusting the angle and height of the patient's head. The top surface of the support frame 12 is fixed... An arc-shaped ring 13 is connected, and a support block 14 is fixedly connected to the center of the inner wall of the arc-shaped ring 13. The arc-shaped ring 13 provides support and positioning for the shooting equipment. One end of the threaded rod 2 is movably connected to the base plate 1, and the other end of the threaded rod 2 passes through the side wall of the base plate 1 and is fixedly connected to the output end of the motor 15. The housing of the motor 15 is fixedly connected to the side wall of the base plate 1. The telescopic frame 3 includes an upper frame 301 and a lower frame 302. A cylinder is fixedly connected to the inner top wall of the upper frame 301, and the bottom surface of the cylinder is fixedly connected to the inner bottom wall of the lower frame 302. The cylinder is not shown in the figure. The outer side wall of the upper frame 301 adapts to the inner side wall of the lower frame 302, connecting the displacement frame 4 and the base plate 1. The vertical height of the displacement frame 4 is controlled by the extension and retraction of the cylinder, realizing the vertical adjustment of the shooting equipment. The first elastic element 6 and the second elastic element 7 are connected. The components are identical, both consisting of a telescopic column 6702 and a spring 6701. One end of the telescopic column 6702 is fixedly connected to one end of the spring 6701. The end of the telescopic column 6702 away from the spring 6701 is a hemispherical structure. The end of the spring 6701 in the first elastic element 6 away from the telescopic column 6702 is fixedly connected to the bottom wall of the groove in the displacement rod 5. The end of the spring 6701 in the second elastic element 7 away from the telescopic column 6702 is fixedly connected to the bottom wall of the groove in the rotating plate 9. The hemispherical structure of the telescopic column 6702 in the first elastic element 6 is located in the groove in the inner wall of the displacement frame 4, and the hemispherical structure of the telescopic column 6702 in the second elastic element 7 is located in the groove in the inner wall of the rotating ring 8. A soft pad 16 is provided on the top surface of the support block 14.Since the imaging equipment comes into direct contact with the patient, a rigid support surface may cause discomfort. The introduction of the soft pad 16 ensures that the contact surface between the imaging equipment and the patient is soft and comfortable, reducing patient discomfort during the examination. The soft pad 16 can be made of memory foam or latex.
[0025] The working principle of this utility model is as follows: The motor 15 is started, which drives the threaded rod 2, causing the telescopic frame 3 to move in the slide groove. The telescopic frame 3 drives the displacement frame 4 and displacement rod 5 above the telescopic frame 3, thereby adjusting the distance between the imaging device and the patient. The electric cylinder is started, which adjusts the height of the telescopic frame 3, thereby adjusting the height of the imaging device. The displacement rod 5 moves within the displacement frame 4, allowing for precise adjustment of the imaging device. The threaded sleeve 11 rotates on the threaded column 10, which allows for adjustment of the height of the arc ring 13, support block 14, and soft pad 16 to accommodate the patient's head and improve comfort. The rotating plate 9 is rotated to ensure that the patient's fundus can be clearly captured by the imaging device.
[0026] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
