[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] An adjustable bracket ophthalmic optometry device includes a device body 9 and a mounting plate 1. A horizontal plate 3 is fixedly connected to the top of the mounting plate 1 via a bracket 2. A connecting sleeve 10 and a longitudinal position adjustment component for fixing the connecting sleeve 10 are integrated on the outer wall of the horizontal end of the bracket 2. The connecting sleeve 10 is fixedly connected to the outer wall of the device body 9. A transmission rod 4 is rotatably connected to the inner wall of the horizontal plate 3. A mandibular bracket 8 and a lifting component for vertical movement of the mandibular bracket 8 are integrated on the outer side of the transmission rod 4. A silicone sponge 13 is integrated on the top of the mandibular bracket 8.

[0025] The patient sits facing the main body 9 of the device, and then adjusts the external seat to position their eyes at a suitable height. Next, the main body 9 is moved vertically so that the connecting sleeve 10 slides along the horizontal end of the bracket 2 until the distance between the main body 9 and the patient's eyes reaches a suitable range. The vertical position of the main body 9 is then fixed by the positioning rod 11. Finally, the transmission rod 4 is rotated, and the engagement of the transmission rod 4 with the screw sleeve 5 provides a pushing force to the screw sleeve 5. The screw sleeve 5 drives the chin support 8 and the sliding sleeve 7 to slide along the vertical end of the bracket 2 until the silicone sponge 13 abuts against the patient's chin, thereby lifting the patient's head. In addition to the adjustable chin support 8, the overall optometry device also expands the vertical adjustment function of the main body 9, thereby increasing the applicability of the adjustable support ophthalmic optometry device.

[0026] Specifically, such as Figure 2 and Figure 4 As shown, a base 15 is fixedly connected to the bottom of the silicone sponge 13. The base 15 is detachably connected to the top of the mandibular bracket 8. A limiting frame 14 is fixedly connected to the top of the mandibular bracket 8, and the limiting frame 14 is fixedly connected to the base 15 through a locking rod 6. The silicone sponge 13 ensures the comfort of the patient's mandible. The base 15 is integrated at the bottom of the silicone sponge 13. The base 15 is placed in the limiting seat 12, and the base 15 is fixed to the limiting frame 14 through the locking rod 6. This ensures the stability of the position of the silicone sponge 13 and facilitates subsequent disassembly and cleaning, thereby improving the convenience of using the adjustable ophthalmic optometry equipment.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the inner wall of the connecting sleeve 10 is slidably connected to the outer wall of the horizontal end of the bracket 2. A positioning rod 11 is screwed onto the top of the connecting sleeve 10, and the open end of the positioning rod 11 abuts against the outer wall of the bracket 2. The longitudinal movement of the device body 9 causes the connecting sleeve 10 to slide along the horizontal end of the bracket 2 until the distance between the device body 9 and the patient's eye reaches a suitable range. The longitudinal position of the device body 9 is then fixed by the positioning rod 11. The open end of the bracket 2 is screwed onto the limiting seat 12, and the limiting seat 12 has a T-shaped cross-section to avoid... The connecting sleeve 10 is completely detached from the bracket 2 without affecting the subsequent independent disassembly and assembly of the main body 9 of the device. The lifting component includes a sliding sleeve 7 and a screw sleeve 5 fixedly connected to the outer wall of the mandibular support 8. The inner wall of the screw sleeve 5 is screwed to the outer wall of the transmission rod 4. The inner wall of the sliding sleeve 7 is slidably connected to the outer wall of the vertical end of the bracket 2. Rotating the transmission rod 4 provides a pushing force to the screw sleeve 5 through the screwing of the transmission rod 4 and the screw sleeve 5. The screw sleeve 5 will drive the mandibular support 8 and the sliding sleeve 7 to slide along the vertical end of the bracket 2 until the silicone sponge 13 abuts against the patient's mandible.

[0028] Working principle: The patient sits facing the main body 9 of the device, and then adjusts the external seat to position their eyes at a suitable height. Next, the main body 9 is moved vertically so that the connecting sleeve 10 slides along the horizontal end of the bracket 2 until the distance between the main body 9 and the patient's eyes reaches a suitable range. The vertical position of the main body 9 is then fixed by the positioning rod 11. Finally, the transmission rod 4 is rotated, and the engagement of the transmission rod 4 with the screw sleeve 5 provides a pushing force to the screw sleeve 5. The screw sleeve 5 then drives the chin support 8 and the sliding sleeve 7 to slide along the vertical end of the bracket 2 until the silicone sponge 13 abuts against the patient's chin, thus achieving the desired eye position. The device supports the patient's head, and in addition to the adjustable chin support 8, the main body 9 of the device is also longitudinally adjustable, thus improving the applicability of the adjustable chin support ophthalmic optometry device. The silicone sponge 13 ensures the patient's chin comfort. A base 15 is integrated at the bottom of the silicone sponge 13. The base 15 is placed in the limiting seat 12, and the base 15 is fixed to the limiting frame 14 by the locking rod 6. This ensures the stability of the silicone sponge 13 and facilitates subsequent disassembly and cleaning, thereby improving the ease of use of the adjustable chin support ophthalmic optometry device.
