Description

Technical Field

[0001] This utility model relates to the field of refractive detection technology, and in particular to a device for detecting the refractive state of the eye. Background Technology

[0002] Eye refraction is an optical distortion phenomenon, including normal vision, myopia, and hyperopia. Eye refraction refers to the refraction of light emitted or reflected from an object through the eye, causing the light to focus on the retina and form a normal image, allowing vision. However, some testing devices cannot adjust the position of the support plate, forcing patients to tilt their heads forward to place their chin on the plate, resulting in a hunched posture and reduced comfort. To address this, patent publication CN220192990U discloses a "device for detecting eye refraction." This design uses a first electric push rod to move a movable plate, support block, and lifting mechanism, allowing adjustment of the lifting mechanism's position. This avoids the hunched posture caused by the patient tilting their head forward, resulting in higher comfort and better performance. Furthermore, the height of the lifting mechanism can be adjusted to suit patients of different heights and body types, making it highly practical.

[0003] However, in this solution, the supporting mechanism is located below the testing platform and flush with one side of the support plate. During the test, the fixing box is likely to press against the patient's chest, resulting in low patient comfort. Therefore, an eye refractive state testing device is proposed. Utility Model Content

An arc plate 10 is fixedly connected to one side of each snap-fit ​​block 9. A silicone pad 11 is fixedly connected to one side of each arc plate 10. The piston end of the two first electric push rods 8 drives the support plate 7 above to move, clamping and fixing the patient's head between the two silicone pads 11. The silicone pads 11 are relatively soft, which improves the comfort of the patient's head when fixing it. Each support plate 7 is provided with a quick-release component 12. To achieve the lifting purpose, the lifting structure 5 includes a bidirectional threaded rod 502 rotatably connected in the first moving groove. A servo motor 501 is fixedly connected to one side of the moving column 2. The output shaft of the servo motor 501 is fixedly connected to one end of the bidirectional threaded rod 502. Two sliding blocks 503 are slidably connected in both the first and second moving grooves. The opposite threads of the bidirectional threaded rod 502 are respectively threaded to the corresponding sliding blocks 503. A rotating frame 504 is fixedly connected to one side of each sliding block 503. A cross support rod 505 is rotatably connected in all four rotating frames 504.

The locking post 123 is slidably connected through one side of the tray 7. The locking post 123 is adapted to the corresponding locking hole. Pulling the sliding rod 122 causes the locking post 123 to move and compress the spring 124, causing the locking post 123 to disengage from the locking hole. Then, the arc plate 10 can be removed, making it convenient for staff to replace the severely worn silicone pad 11.

[0018] Working principle: The servo motor 501 drives the bidirectional threaded rod 502 to rotate, which in turn drives the corresponding sliding block 503 to move. The sliding block 503 then drives the corresponding rotating frame 504 to move. The rotating frame 504 pushes the upper support column 4 to move via the cross support rod 505, thereby moving the two support plates 7 on one side. This is suitable for patients of different heights and does not press against the patient's chest during testing, thus improving the patient's comfort. Pulling the sliding rod 122 causes the locking column 123 to move and compresses the spring 124, disengaging the locking column 123 from the locking hole. Then, the arc plate 10 can be removed, making it convenient for staff to replace the severely worn silicone pad 11.
