[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] This invention provides a multifunctional enzyme-linked immunosorbent assay (ELISA) reader, such as... Figures 1 to 6 As shown, the device includes a multifunctional ELISA reader body 1, which consists of a light source system, a detection system, and a control system. A protective door 2 is movably connected to one end of the multifunctional ELISA reader body 1. A movable plate 3 is movably connected to the inside of the protective door 2 at one end of the multifunctional ELISA reader body 1. A fixing groove 4 is opened inside the movable plate 3, and a microplate is placed inside the fixing groove 4. Multiple trays 5 are fixedly connected to the movable plate 3 at the position of the fixing groove 4. A spring telescopic rod 6 is fixedly connected to the movable plate 3 above the trays 5. A squeezing block 7 is fixedly connected to the movable end of the spring telescopic rod 6. A protective pad 8 is adhered to the movable plate 3 at the position corresponding to the squeezing block 7.

[0025] like Figure 1 and Figure 5 As shown, a fixed frame 9 is movably connected to the other end of the multi-functional microplate reader body 1. Locking blocks 10 are fixedly connected to both ends of the fixed frame 9, and the locking blocks 10 are movably connected to the interior of the multi-functional microplate reader body 1. A limiting block 11 is fixedly connected to one end of the locking block 10, and the limiting block 11 is movably connected to the interior of the multi-functional microplate reader body 1. A positioning groove 12 is provided inside the fixed frame 9, and a positioning block 13 is locked at the position of the positioning groove 12 inside the fixed frame 9. A louver 14 is fixedly connected to one end of the positioning block 13. The locking combination of the positioning block 13 and the positioning groove 12 enables quick disassembly and installation of the louver 14, facilitating cleaning of the louver 14 and improving the maintenance efficiency of the louver 14.

[0026] like Figure 1 and Figure 3 As shown, the protective pad 8 is rectangular in shape and made of rubber. The protective pad 8 can enhance the stability of the microplate and protect the microplate after being squeezed, thus improving the durability of the microplate.

[0027] like Figure 1 and Figure 3 As shown, the multiple trays 5 have the same thickness and the top surfaces of the multiple trays 5 are located on the same horizontal line, ensuring that the micro-tablet remains stable in the horizontal direction when placed on the surface of the tray 5, and ensuring that the micro-tablet can be used normally.

[0028] like Figure 1 and Figure 5 As shown, the width of the limiting block 11 is greater than the width of the card block 10. The limiting block 11 limits the fixing frame 9, preventing the fixing frame 9 from sliding out of the multi-functional microplate reader body 1, thus improving the reliability of the fixing frame 9.

[0029] like Figure 1 and Figure 6As shown, the positioning block 13 is rectangular in shape, and the size of the positioning block 13 is the same as that of the positioning groove 12, which can achieve precise alignment, ensure a stable connection between the fixed frame 9 and the louver 14, and improve the stability of the louver 14.

[0030] Working principle: In actual use, the sample to be tested is first added to different holes of the microplate. After installation, the microplate is aligned with the fixing groove 4, and then the microplate is moved downward. When the microplate reaches the same horizontal height as the extrusion block 7, the microplate is moved towards the extrusion block 7. The microplate applies a force to the extrusion block 7, which in turn applies a force to the spring telescopic rod 6. The spring telescopic rod 6 retracts, causing the extrusion block 7 to move synchronously, thus moving the microplate. When the bottom surface of the microplate contacts the support plate 5 and the side surface contacts the protective pad 8, the microplate is positioned. Then, due to the elastic force of the spring telescopic rod 6, the extrusion block 7 presses the microplate, which can effectively improve the stability of the microplate and ensure that the microplate remains stationary during the test, providing a reliable fixation and pressing effect for subsequent test operations.

[0031] Then, when the dust and impurities accumulated inside the louver 14 after long-term use need to be cleaned, the locking block 10 is moved outward by the fixing frame 9, so that the locking block 10 is no longer locked inside the multifunctional microplate reader body 1. Then, the positioning block 13 is no longer locked with the positioning groove 12 by the louver 14. When the positioning block 13 is no longer locked with the positioning groove 12, the louver 14 can be removed, which can realize the quick disassembly and installation of the louver 14, facilitate the cleaning of the louver 14, and improve the maintenance efficiency of the louver 14.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
