[0013] Beneficial effects
[0014] This invention provides a slit lamp for clinical ophthalmic examination. Compared with the prior art, it has the following advantages:
[0015] 1. This slit lamp for clinical ophthalmic testing uses a rotating control block to drive a control screw. The rotation of the control screw causes a sliding plate to slide on the surface of a limiting rod. The sliding of the sliding plate causes one end of a rotating rod to rotate inside the sliding plate, while the other end of the rotating rod rotates on the top of the mounting plate. This allows the mounting plates on both sides to slide synchronously to opposite sides on the surface of the limiting slide rail, into the mounting grooves opened inside the mounting plate slide assembly block. This enables the disassembly of the support frame, facilitating maintenance and cleaning of the entire support frame. The installation mechanism allows for quick installation and disassembly of the entire support frame. After work, components such as the chin rest, fixing plate, or cushion can be cleaned and disinfected, thus improving the cleanliness and safety of the equipment.
[0016] 2. This slit lamp for clinical ocular examination utilizes a mechanism where rotating the fixing screw on the outer side of the right-side fixing plate causes the right-side fixing plate and soft pad to slide synchronously to the left. This sliding of the right-side fixing plate, in turn, causes the right-side linkage block, linkage plate, and linkage gear plate to slide synchronously to the left. The sliding of the right-side linkage gear plate then drives a rotating gear, which in turn causes the left-side linkage gear plate, linkage plate, linkage block, fixing plate, and soft pad to slide synchronously to the right. This simultaneous clamping and fixation of the patient by the fixing plates and soft pads on both sides facilitates subsequent clinical ocular examination by the slit lamp body. The fixing components, along with the fixing plates and soft pads on both sides, clamp and fix the patient's head, maintaining stability during the examination and improving the quality of clinical ocular examination. Furthermore, the linkage components allow for synchronous adjustment of the positions of the fixing plates on both sides. Attached Figure Description

[0032] In this embodiment, the top of the mounting base 3 is provided with a symmetrical mounting groove 7, and the bottom end of the support frame 5 is fixedly connected with a symmetrical mounting block 8. The mounting block 8 is adapted to the mounting groove 7, and the inner side of the mounting block 8 is provided with an installation groove 9. The inner surface of the installation groove 9 is engaged with one end of the mounting plate 414.
[0033] With the installation mechanism 4, the support frame 5 can be quickly installed and disassembled as a whole, which facilitates the cleaning and disinfection of structural components such as the chin support 10, the fixing plate 64 or the soft pad 65 after the work is completed, thereby improving the cleanliness and safety of the equipment.
[0034] In this embodiment, the fixing component 6 includes a bearing plate 61 installed inside the support frame 5. A rotating gear 62 is rotatably connected inside the bearing plate 61.

[0035] The fixing plate 64 has two symmetrical pieces installed, and the fixing screw 66 is rotatably installed on the outside of the right fixing plate 64. Both sets of fixing plates 64 have support rods for sliding limit installed on their outer sides.
[0036] In this embodiment, the linkage assembly 63 includes a linkage toothed plate 631 that is slidably installed on the inner wall of the support plate 61. One side of the linkage toothed plate 631 meshes with the surface of the rotating gear 62. One end of the linkage toothed plate 631 is fixedly connected to a linkage plate 632. The top of the linkage plate 632 is fixedly connected to the bottom of the fixed plate 64 through a linkage block.
[0037] The inner wall of the bearing plate 61 is equipped with symmetrical positioning strips. The linkage tooth plate 631 slides on the surface of the positioning strips, and the positioning strips can limit the sliding of the linkage tooth plate 631.
[0038] In this embodiment, a chin support 10 is installed at the center of the top of the support plate 61, and linkage grooves 11 are provided on both sides of the top of the support plate 61. The inner surface of the linkage groove 11 is slidably connected to the surface of the linkage block.
[0039] By incorporating a fixing component 6, the patient's head can be clamped and fixed using the fixing plates 64 and soft pads 65 on both sides, maintaining the stability of the patient's head during the examination, thereby improving the quality of clinical ophthalmic examination. Furthermore, by incorporating a linkage component 63, the positions of the fixing plates 64 on both sides can be adjusted synchronously.
[0040] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0041] During operation, the patient first rests their chin on the top of the chin rest 10. Then, by rotating the fixing screw 66 on the outer side of the right fixing plate 64, the right fixing plate 64 and the soft pad 65 slide synchronously to the left. The sliding of the right fixing plate 64 causes the right linkage block, linkage plate 632, and linkage toothed plate 631 to slide synchronously to the left. The sliding of the right linkage toothed plate 631 causes the rotating gear 62 to rotate. The rotation of the rotating gear 62 causes the left linkage toothed plate 631, linkage plate 632, linkage block, fixing plate 64, and soft pad 65 to slide synchronously to the right. In this way, the patient is simultaneously clamped and fixed by the fixing plates 64 and soft pad 65 on both sides, which facilitates subsequent... The slit lamp body 2 performs clinical examinations on the patient's eyes. After the work is completed, the control screw 421 can be rotated by rotating the control block 422. The rotation of the control screw 421 will cause the sliding plate 412 to slide on the surface of the limiting rod 411. The sliding of the sliding plate 412 will cause one end of the rotating rod 413 to rotate inside the sliding plate 412, and the other end of the rotating rod 413 to rotate on the top of the mounting plate 414. This allows the mounting plates 414 on both sides to slide synchronously to the opposite side on the surface of the limiting slide rail 415, so that the mounting plate 414 slides into the mounting groove 9 opened inside the mounting block 8, thereby enabling the disassembly of the support frame 5, which facilitates the maintenance and cleaning of the support frame 5 as a whole.
