[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 to Figure 3 This embodiment provides a medical magnifying glass optical tester, including a detection mechanism 100 and a positioning mechanism 200, wherein the detection mechanism 100 is used to detect the optical performance of the medical magnifying glass, and the positioning mechanism 200 is used to accurately position lenses of different shapes and specifications to ensure that the lenses are in a stable test position during the detection process.

[0033] Specifically, the detection mechanism 100 includes a detection table 101, which is used to support the entire detection device and provide a stable test platform. A tray 102 is fixedly installed at the center of the top of the detection table 101. The tray 102 is used to place and fix the medical magnifying glass to ensure the stability and accurate positioning of the lens during the detection process. A support plate 103 is fixedly installed on the rear side wall of the detection table 101. The support plate 103 plays the role of supporting the detector body to ensure the stable installation of the detection equipment. The detector body 104 is fixedly installed on the front side of the top of the support plate 103. The detector body 104 is responsible for performing optical performance tests, and its detection probe is set directly above the tray 102, which can accurately align with the medical magnifying glass lens placed on the tray for detection, ensuring the accuracy and reliability of the test data.

[0034] More specifically, the positioning mechanism 200 includes a clamping plate 201 arranged on the left and right sides of the tray 102. The clamping plate 201 is used to clamp and fix lenses of different specifications to ensure that they remain stable during the detection process. The back surfaces of the two clamping plates 201 are movably connected with a connecting plate 202. The connecting plate 202 not only supports the clamping plate, but also can flexibly adjust its position to adapt to lenses of different sizes. A positioning component 203 is installed inside the connecting plate 202. The positioning component 203 can not only firmly fix the clamping plate 201 on the connecting plate 202, but also facilitates the rapid disassembly and replacement of the clamping plate as needed. The clamping plate 201 in the figure is an arc-shaped design, but it can be replaced with a square clamping plate according to the shape of the lens to adapt to lenses of different models. The bottom end of the connecting plate 202 is fixedly connected to the moving block 205 through a connecting rod 204. The moving block 205 controls the translation of the clamping plate to make the positioning more accurate. The two moving blocks 205 are connected by a driving assembly 206 , which drives the moving blocks 205 to move horizontally relative to or opposite to each other, thereby driving the connecting plate 202 and the clamping plate 201 to move synchronously, thereby achieving accurate clamping and fixing of the lens to be tested on the tray 102 .

[0035] More specifically, a rotating cavity 101a is provided at the center of the interior of the testing platform 101, and the rotating cavity 101a provides a space for the installation and operation of the driving component. Moving cavities 101b are symmetrically provided on the left and right sides of the rotating cavity 101a. The moving cavity 101b provides a channel for horizontal movement of the moving block to ensure that the splint and the connecting plate can move smoothly during positioning. Moving grooves 101c are provided at the tops of the two moving cavities 101b, and the moving grooves 101c are used to guide the movement of the connecting rod to ensure that the connecting rod and the moving block slide more smoothly.

[0036] Furthermore, the driving assembly 206 includes a worm wheel 206a rotatably connected to the center of the rotating chamber 101a, and the worm wheel 206a drives the operation of the entire driving system through a transmission device. The bottom end of the worm wheel 206a is meshedly connected with a worm 206b, and the rotation of the worm 206b drives the worm wheel to rotate, completing mechanical transmission. The front end of the worm 206b passes through the rotating chamber 101a and extends to the outside of the testing platform 101, and is fixedly connected with a knob 206c. The knob 206c is used to manually control the rotation of the worm, thereby adjusting the operation of the driving system. A rotating shaft 206d is fixedly installed at the center of the worm wheel 206a, and the rotating shaft 206d provides a stable rotation support for the worm wheel and transmits the transmission power to both sides. Threaded rods 206e are symmetrically installed on the left and right ends of the rotating shaft 206d, and the threaded rods 206e are connected to the moving block. By adjusting the rotation direction of the thread, the splint and the connecting plate can be synchronously moved or relatively moved, thereby achieving precise positioning and fixation of the lens.

[0037] It should be noted that the two moving blocks 205 are connected to the outer surfaces of the two threaded rods 206e respectively through threads, and this threaded connection structure enables the moving blocks to move smoothly along the length direction of the threaded rods. More importantly, the threads on the outer surfaces of the two threaded rods 206e are in opposite directions. The purpose of this design is that when the threaded rods 206e rotate forward, the two moving blocks 205 will move horizontally in opposite directions, and then drive the two connecting plates 202 and the clamping plate 201 to move outward in opposite directions through the two connecting rods 204. This design can quickly adjust the distance between the clamping plates to adapt to larger-sized lenses. Similarly, when the staff rotates the knob 206c in the opposite direction, the threaded rod 206e rotates in the opposite direction, and the two moving blocks 205 will move horizontally relative to each other, driving the two clamping plates 201 to move closer to each other, and finally firmly clamping the lens on the tray 102 to ensure that it remains stable and does not shake during the optical detection process.

[0038] According to the above content, the working principle of the lens detection of the present invention is as follows:

[0039] First, the lens of the medical magnifying glass is placed on the tray 102 on the top of the testing table 101, and the tray 102 provides a stable supporting platform. The two clamping plates 201 in the positioning mechanism 200 are used to clamp and fix the lens to ensure that the lens remains stable and does not move during the testing process. Through the driving assembly 206, the staff can manually rotate the external knob 206c to drive the worm 206b and the worm wheel 206a to perform mechanical transmission, thereby driving the threaded rods 206e on both sides to rotate. Since the threaded rods 206e have opposite thread rotation directions, when the threaded rods rotate forward, the two moving blocks 205 move back to each other, and the clamping plate 201 expands outward accordingly to adapt to the larger size of the lens; when the threaded rods rotate in the opposite direction, the moving blocks 205 move relatively, driving the clamping plates 201 to move closer to each other, and finally firmly clamping the lens to ensure that it is fixed during the optical test process. After the lens is firmly fixed, the detector body 104 in the detection mechanism 100 aligns the lens with its detection probe to detect the optical performance. The detection process ensures that the optical properties of the lens can be accurately measured, and the reliability of the detection data is guaranteed. Through such a design, the present invention can adapt to lenses of different shapes and sizes, is easy to operate and has accurate positioning, and ensures that the optical detection process of the medical magnifier is efficient and stable.

[0040] Example 2

[0041] Reference Figure 2 to Figure 6 , which is the second embodiment of the present invention, is based on the previous embodiment, and is different from the previous embodiment in that:

[0042] In this embodiment, the structure of the positioning mechanism 200 is improved, especially by adding an adjustment mechanism (i.e., positioning assembly 203) at the connection between the connecting plate 202 and the clamping plate 201, so that the clamping plate 201 can be replaced more conveniently and quickly to adapt to different types of lenses, further improving the flexibility and applicability of the device.

[0043] Specifically, the opposite surfaces of the two connecting plates 202 are fixedly installed with fixing plates 207, which are used to support and connect the clamping plates 201 to ensure that the clamping plates can be firmly installed and positioned. The opposite surfaces of the two fixing plates 207 are provided with slots 207a, which are used to accommodate plug-in plates 208, thereby realizing the limit fixation and position adjustment of the clamping plates 201. The opposite back surfaces of the two clamping plates 201 are fixedly installed with plug-in plates 208 that are compatible with the slots 207a. The plug-in plates 208 are plugged into the slots 207a, so that the clamping plates 201 are firmly connected to the fixing plates 207. At the same time, the structural design of the plug-in plates 208 also ensures the rapid disassembly and replacement of the clamping plates. The interiors of the two plug-in plates 208 are provided with positioning slots 208a, which are used to cooperate with the positioning plates 203a to ensure that the plug-in plates 208 are limited and fixed in the slots 207a, thereby ensuring the stability of the clamping plates 201.

[0044] Furthermore, the positioning assembly 203 includes a positioning plate 203a slidably connected to the top of the fixed plate 207. The positioning plate 203a can flexibly adjust its position through a sliding connection to ensure that it can be inserted into the positioning groove 208a of the plug plate 208 to achieve precise limit fixation of the splint. The top of the positioning plate 203a is internally slidably connected with a movable rod 203b. The movable rod 203b can slide inside the positioning plate 203a to transmit the movement from the transmission plate 203c, so that the positioning plate 203a can move up and down. The design of the movable rod ensures that the positioning plate can move smoothly during positioning and release.

[0045] Furthermore, a telescopic groove 202a is provided inside the connecting plate 202, and the telescopic groove 202a provides space for the telescopic spring 203d and the pressure plate 203f in the positioning assembly. The function of the telescopic spring 203d is to provide a reset elastic force so that the positioning assembly can automatically return to its initial position after use. A movable groove 202b is provided on the outer side of the top end of the connecting plate 202, and the movable groove 202b provides installation and movable space for the positioning rod 203e in the positioning assembly. The positioning rod 203e serves as the rotation axis of the transmission plate 203c, ensuring that the positioning assembly can work smoothly when the pressure plate is operated.

[0046] Furthermore, the positioning assembly 203 also includes a telescopic spring 203d fixedly connected to the telescopic slot 202a. The telescopic spring 203d is used to restore the positioning plate 203a to the initial position after the pressure block 203g is released to ensure that the clamping plate can be firmly fixed. The top of the telescopic spring 203d is fixedly connected to a pressure plate 203f. The pressure plate 203f drives the operation of the transmission assembly by pressing. The top of the pressure plate 203f passes through the telescopic slot 202a and extends to the outside of the connecting plate 202. The outside is connected to a pressure block 203g. The pressure block 203g is a component operated by the staff. After being pressed, it can drive the entire transmission mechanism to work and realize the release of the limit of the clamping plate.

[0047] It is worth noting that the other end of the transmission plate 203c is sleeved on the outer surface of the positioning rod 203e, and the positioning rod 203e serves as the rotation center of the transmission plate to ensure that the transmission plate can rotate smoothly around the positioning rod. The outer surface of one end of the transmission plate 203c that is rotatably connected to the positioning rod 203e is provided with an annular tooth 203h, and the annular tooth 203h is used to mesh with the rack 203i on the pressing plate 203f. The pressing plate 203f is fixedly installed with a rack 203i on one side close to the transmission plate 203c, and the rack 203i is meshed with the annular tooth 203h, which can drive the rotation of the transmission plate 203c through the movement of the pressing plate, so that the positioning plate 203a moves up and down, thereby fixing or loosening the plug plate.

[0048] In summary, the clamping plate 201 is inserted into the slot 207a of the fixed plate 207 through the plug plate 208, and the fixed plate 207 is slidably connected with the positioning plate 203a inside, and the plug plate 208 is provided with a positioning groove 208a inside. The plug plate 208 can be fixed in the slot 207a through the positioning plate 203a, so that the clamping plate 201 can be fixed in position with the fixed plate 207; Figure 4As shown, when the staff presses the pressing block 203g downward, the pressing block 203g can drive the pressing plate 203f to move downward, and the bottom end of the pressing plate 203f can squeeze the telescopic spring 203d. At the same time, the rack 203i on the other side of the pressing plate 203f can drive the annular gear 203h to rotate counterclockwise, and the annular gear 203h can drive the transmission plate 203c to rotate counterclockwise with the positioning rod 203e as the axis, and the other end of the transmission plate 203c can drive the positioning plate 203a to move vertically upward (it should be noted that the other end of the transmission plate 203c is rotatably connected by the movable rod 203b, and the movable rod 203b is slidably connected to the positioning plate 203a Therefore, when the other end of the transmission plate 203c rotates, the movable rod 203b can be pulled to the left for a distance to ensure that the positioning plate 203a can move vertically upward), thereby releasing the limit fixation of the plug plate 208, and the staff can remove the clamping plate 201 from the fixed plate 207, so that different types of clamping plates 201 can be replaced. After the replacement is completed, the staff releases the pressure block 203g, and under the action of the rebound force of the telescopic spring 203d, the positioning assembly 203 can be rebounded to the initial position as a whole, and the positioning plate 203a can be reinserted into the positioning slot 208a of the new plug plate 208, thereby completing the replacement and installation of the clamping plate 201.
