[0026] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0027] Reference Figures 1 to 3 The objective lens lifting device disclosed in this embodiment includes: a Z-axis translation mounting seat 10, a transmission assembly 20 and a reversing gear box 30;

[0028] The Z-axis translation mounting seat 10 includes a translation ring 11 for assembling an objective lens and a differential head 12 for driving the translation ring 11, wherein the axial direction of the differential head 12 is a vertical direction;

[0029] The output end of the transmission assembly 20 is connected to the differential head 12, and the input end of the transmission assembly 20 is connected to the output shaft 31 of the reversing gear box 30. The output shaft 31 of the reversing gear box 30 is transmission-connected to the input shaft 32, and the input shaft 32 of the reversing gear box 30 is horizontally arranged.

[0030] The transmission assembly 20 is responsible for transmitting the input of the reversing gear box 30 to the micrometer head 12. The operator can realize the lifting and focusing adjustment of the objective lens by rotating the input shaft 32 of the reversing gear box 30. By introducing the transmission assembly 20 and the reversing gear box 30, the operating position is transferred from the central area close to the objective lens to the edge area away from the objective lens. Therefore, there is a more spacious operating space, avoiding the inconvenience of operation caused by the narrow space in the central area, and improving the convenience of operation. In addition, the input shaft 32 of the reversing gear box 30 is horizontally arranged, which conforms to the ergonomic design, reduces the burden on the operator, and improves the comfort of operation.

[0031] Furthermore, the input shaft 32 of the reversing gear box 30 is connected to a manual adjustment knob 40 or a stepper motor. The manual adjustment knob 40 allows the user to make small and flexible adjustments during debugging and testing, while the stepper motor can achieve high-precision automatic adjustment through program control. This makes the device applicable not only to conventional laboratory microscopic imaging tasks, but also to automated analysis tasks that require high precision and high repeatability.

[0032] Reference Figure 1 to Figure 2 The transmission assembly 20 includes a synchronous belt 21 and a synchronous wheel 22. One end of the synchronous belt 21 is sleeved on the differential head 12 and is in transmission connection with the differential head 12. The other end of the synchronous belt 21 is sleeved on the synchronous wheel 22 and is in transmission connection with the synchronous wheel 22. The synchronous wheel 22 is fixed on the output shaft 31 of the reversing gear box 30. The transmission design using the synchronous belt 21 and the synchronous wheel 22 has efficient and smooth power transmission characteristics, can maintain a constant transmission ratio, reduces slippage and errors in the transmission process, and improves the transmission accuracy of the overall system. This is particularly important for the precise lifting and lowering adjustment of the objective lens in microscopic imaging, which can ensure the imaging quality.

[0033] Reference Figure 1 to Figure 2 The transmission assembly 20 also includes a tensioning wheel 23, which is located on the inner side of the synchronous belt 21 and is connected to the synchronous belt 21 in a transmission manner. The tensioning wheel 23, the differential head 12, and the synchronous wheel 22 are arranged in a triangle. The tensioning wheel 23 is used to maintain the appropriate tension of the synchronous belt 21 to prevent the synchronous belt 21 from loosening or slipping during the transmission process, thereby ensuring the stability and accuracy of the transmission; the tensioning wheel 23, the differential head 12, and the synchronous wheel 22 are arranged in a triangle, which can provide a more uniform tension distribution and improve the stability of the system.

[0034] Furthermore, the diameter of the synchronous wheel 22 is smaller than that of the differential head 12, and the change of the transmission ratio allows each rotation input to produce a smaller output angle change, thereby greatly improving the fineness of the adjustment, which is particularly suitable for environments where micron-level adjustment is required during microscopic imaging.

[0035] The reversing gear box 30 includes a vertically arranged output shaft 31 and a horizontally arranged input shaft 32, and the output shaft 31 is connected to the input shaft 32 through gear transmission. The horizontal arrangement of the input shaft 32 conforms to the ergonomic design, and the operator can adjust in a more comfortable posture, reduce fatigue, and improve operating efficiency; the gear transmission connection ensures efficient transmission and precise control of power, reduces energy loss and transmission error, and improves the accuracy and stability of the objective lens lifting.

[0036] Furthermore, the transmission ratio of the input shaft 32 to the output shaft 31 is greater than 1. A transmission ratio greater than 1 indicates that the output shaft 31 rotates at a lower speed relative to the input shaft 32, achieving a deceleration effect. In the objective lens lifting device, this deceleration design can make the lifting movement slower and more stable, which is conducive to accurate lens adjustment and focusing operations.

[0037] Reference Figure 3 The cell microscopic imaging analyzer disclosed in this embodiment includes the above-mentioned objective lens lifting device. The input shaft 32 of the reversing gear box 30 is arranged on the side of the cell microscopic imaging analyzer, which makes the operation more convenient, avoids the difficulty of operation in the narrow space of the central area, and improves the comfort and efficiency of operation. A manual adjustment knob 40 is connected to the input shaft 32 of the reversing gear box 30. By rotating the manual adjustment knob 40 on the side of the cell microscopic imaging analyzer, the lifting and focusing operation of the objective lens located in the central area of ​​the analyzer can be realized.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
