Description

Technical Field

[0001] This utility model relates to the field of optometry technology, and in particular to a comprehensive optometry instrument for ophthalmology. Background Technology

[0002] Some ophthalmic refractometers have jaw and facial support components that frequently come into contact with the patient's face, making them prone to accumulating dirt and bacteria, and difficult to clean. Furthermore, these support components may wear out or deform after prolonged use, requiring replacement. However, existing support mechanisms are often not conveniently designed, and the cleaning and replacement process is cumbersome, affecting the efficiency and hygiene of the refractometer.

[0003] In the prior art, Chinese patent document CN216317537U discloses a comprehensive optometry instrument for ophthalmology. This instrument features a support frame with a stabilizing block fixedly connected internally. A lead screw is rotatably connected internally to the stabilizing block, and a moving block is threaded onto the surface of the lead screw. A handle is fixedly connected to one end of the lead screw, and a moving plate is fixedly connected to the top of the moving block. A fitting component is located on one side of the moving plate, and a face rest is fixedly connected to one end of the fitting component. A lifting component is located on the top of the support frame. This comprehensive optometry instrument for ophthalmology provides an adjustable function. The jaw rest can be adjusted up and down via an electric telescopic rod. Adjusting the width of the face rests on both sides allows the patient's head to be placed between the jaw rest and the face rest, reducing fatigue from prolonged testing and providing a more comfortable testing environment. However, consistent with conventional technologies, the forehead support height is fixed, making operation cumbersome and difficult to quickly and accurately adapt to patients of different ages and heights, thus affecting the efficiency and accuracy of the refraction test. The jaw support, as the part that comes into direct contact with the patient's face, is prone to accumulating dirt and bacteria. Furthermore, the design of the jaw support is often inconvenient for disassembly and cleaning, increasing the risk of cross-infection, affecting the hygiene of medical equipment, and resulting in poor practicality. Therefore, this utility model discloses an ophthalmic comprehensive optometry instrument to solve the problems of inconvenient adjustment of the forehead support and inconvenient cleaning of the jaw support in comprehensive optometry instruments.

[0019] This utility model provides, for example Figures 1 to 5The ophthalmic comprehensive optometry instrument shown includes: a mounting platform 1, an optometry machine 2 mounted on the upper part of the mounting platform 1, and two concave slide rails 3 mounted on one side of the upper part of the mounting platform 1 opposite to the optometry machine 2. A forehead support 4 is mounted on the top of the two concave slide rails 3, and a first elastic pad 5 is attached to the side of the forehead support 4 that is in contact with the forehead. An adjustment component is provided on the concave slide rails 3 for adjusting the height of the forehead support 4. Multiple sets of support rods 1 are mounted on the mounting platform 1 on the side of the concave slide rails 3 away from the optometry machine 2. 3. Each of the multiple support rods 13 has a support sleeve 12 installed at its top, and the other end of each support sleeve 12 is connected to a jaw support 14. An L-shaped arc plate 16 is installed on the upper part of the jaw support 14, and a portable component is installed on the jaw support 14 for easy disassembly of the L-shaped arc plate 16. This invention uses a concave slide rail 3 and an adjustment component design. Through the cooperation of the vertical screw 7, screw sleeve 8, convex slider 9, and vertical guide rod 10, the height of the forehead support 4 can be quickly adjusted. The adjustment process is simple and intuitive. The operator only needs to rotate the vertical screw 7 to easily adjust the height of the forehead support 4, adapting to patients of different ages and heights, and improving the efficiency and accuracy of refraction. The jaw support 14 is connected to the support sleeve 12 through the portable component, and the L-shaped arc plate 16 is detachably connected to the jaw support 14 through the cooperation of the horizontal guide rod 17 and the guide channel 15. The disassembly process is simple and convenient. Operators only need to loosen the locking frame 21 to remove the L-shaped arc plate 16 from the jaw support 14 for cleaning and disinfection, which effectively prevents cross-infection and improves the hygiene of medical equipment.

[0020] Furthermore, in this example, such as Figure 3 As shown, the other end of the support rod 13 is slidably inserted into the middle of the bottom end of the support sleeve 12, and a first support spring 19 is installed inside the support sleeve 12. One end of the first support spring 19 is installed on the top inner wall of the support sleeve 12, and the other end of the first support spring 19 is installed on the top side wall of the support rod 13. When the head is placed on the L-shaped arc plate 16, the person's jaw will exert downward pressure, thereby compressing the first vertical spring 19, thereby driving the support sleeve 12 to slide downward on the support rod 13. Because the compression of the first vertical spring 19 stores elastic potential energy, it achieves the purpose of supporting the person's jaw.

[0021] Furthermore, in this example, such as Figure 1 and Figure 5As shown, the adjustment assembly includes two concave slide rails 3. Each concave slide rail 3 has a concave groove on its opposite sidewall. A convex slider 9 is slidably mounted on each concave groove. Vertical guide rods 10 are mounted on the upper and lower ends of the convex sliders 9, and vertical springs 11 are sleeved on the vertical guide rods 10. A mounting block 6 is mounted on the top of the concave slide rails 3. A groove is formed on one side of the convex slider 9 on the mounting block 6, and a threaded sleeve 8 is installed in the groove. A vertical screw 7 is mounted on the top of the mounting block 6. A through hole with the same diameter as the vertical guide rod 10 is formed on the convex slider 9 corresponding to the position of the vertical guide rod 10. One end of the vertical spring 11 is abutted against the lower wall of the convex slider 9. The other end abuts against the upper surface of the mounting platform 1. A through hole with the same diameter as the vertical screw 7 is provided on the mounting block 6 at the position corresponding to the vertical screw 7. The through hole is located at the upper and lower ends of the groove on the side wall of the mounting block 6. A circular hole for meshing with the vertical screw 7 is provided in the middle of the threaded sleeve 8. The vertical screw 7 passes through both the upper and lower ends of the mounting block 6 and the threaded sleeve 8. The lower end of the vertical screw 7 abuts against the upper surface of the convex slider 9. The convex slider 9 is located in the concave groove of the concave slide rail 3 and is connected to the mounting platform 1 via a vertical guide rod 10. A vertical spring 11 is sleeved on the vertical guide rod 10 and is in a compressed state, providing a certain preload force to the convex slider 9. The mounting block 6 is fixed to the top of the concave slide rail 3, the threaded sleeve 8 is installed in the groove of the mounting block 6, and the vertical screw 7 passes through the mounting block 6 and the threaded sleeve 8, with its lower end abutting against the upper surface of the convex slider 9. The operator rotates the screw sleeve 8. Because the screw sleeve 8 engages with the vertical screw 7, the vertical screw 7 moves up and down along its axis. When the vertical screw 7 moves downward, it presses against the convex slider 9, overcoming the preload of the vertical spring 11, causing the convex slider 9 to slide downward within the concave groove, thereby lowering the forehead support 4. When the vertical screw 7 moves upward, it releases the pressure on the convex slider 9, and the preload of the vertical spring 11 causes the convex slider 9 to slide upward within the concave groove, thereby raising the forehead support 4. After adjustment, the operator stops rotating the screw sleeve 8. Due to the engagement between the screw sleeve 8 and the vertical screw 7, the vertical screw 7 remains in its current position, thus locking the height of the forehead support 4 to accommodate patients of different ages and heights, improving the efficiency and accuracy of refraction testing.

[0022] Furthermore, in this example, such as Figure 2 and Figure 4As shown, the portable component includes an L-shaped arc plate 16. Multiple sets of horizontal guide rods 17 are mounted on the inner side of the short arm of the L-shaped arc plate 16. The L-shaped arc plate 16 matches the upper surface dimension of the jaw support 14. Guide channels 15 are provided on the jaw support 14 corresponding to the positions of each set of horizontal guide rods 17. A second elastic pad 18 is adhered to the outer wall of the long arm of the L-shaped arc plate 16. A mounting groove 20 is provided at the end of the horizontal guide rod 17 located in the middle of the L-shaped arc plate 16. The two end sidewalls of the mounting groove 20 are vertically divided... A rotating rod 23 is installed on each of the two rotating rods 23, and a locking frame 21 is rotatably mounted on each of the two rotating rods 23. A second support spring 22 is mounted on the opposite sidewalls of the two locking frames 21. One end of each locking frame 21 has a circular hole with the same diameter as the rotating rod 23 at the corresponding position. Multiple anti-slip grooves are formed on the outer surface of the second elastic pad 18. An L-shaped arc plate 16 is inserted into the guide channel 15 of the jaw support 14 via a horizontal guide rod 17, thus connecting with the jaw support 14. The locking frame 21 is installed in the mounting groove 20 at the end of the horizontal guide rod 17 in the middle of the L-shaped arc plate 16 via the rotating rod 23. The second support spring 22 is installed between the two locking frames 21 and is in a compressed state, providing preload force to the locking frames 21. The operator presses the locking frame 21 inward, overcoming the preload force of the second support spring 22, causing the locking frame 21 to move out of the locked position of the guide channel 15. When the locking bracket 21 no longer obstructs the horizontal guide rod 17, the operator can remove the L-shaped arc plate 16 from the jaw support 14 along the guide channel 15. To install the L-shaped arc plate 16, the operator aligns the horizontal guide rod 17 of the L-shaped arc plate 16 with the guide channel 15 of the jaw support 14, inserts it, and pushes it into place. Once the end of the locking bracket 21 leaves the guide tube 15, the preload of the second support spring 22 returns the locking bracket 21 to the locked position, firmly locking the horizontal guide rod 17 within the guide channel 15, thus completing the installation of the L-shaped arc plate 16. After removing the L-shaped arc plate 16, it is cleaned and disinfected, effectively preventing cross-infection and improving the hygiene of the medical equipment.
