Therefore, it will not be described here. The following will describe the main protection of the waste liquid suction mechanism 3.

[0038] As shown in the figure, Figure 1 In some embodiments, the bottom plate of the warehouse body 21 is fixed on the mounting bottom plate 11, and the waste liquid suction mechanism 3 is fixed on the plate surface of the mounting bottom plate 11 extending outward relative to the peripheral side wall of the warehouse body 21. In other alternative embodiments, the bottom plate of the warehouse body 21 can be an integral structure with the mounting bottom plate 11; or the mounting bottom plate 11 is fixed on the outer periphery of the bottom plate of the warehouse body 21.

[0039] As shown in the figure, Figure 2 and Figure 3As shown, the waste suction mechanism 3 comprises a mounting bracket 31, a driving member 32, a lifting assembly 33 and a waste suction assembly 34. The mounting bracket 31 is fixedly connected with the mounting bottom plate 11. The driving member 32 is installed on one side of the mounting bracket 31 and at least partially located in the installation space below the bin body 21. The lifting assembly 33 is located outside the sidewall of the bin body 21 and driven by the driving member 32 to make lifting movement. The waste suction assembly 34 is connected with the lifting assembly 33 and located directly above the light measuring disc and is provided with a waste suction needle 341 for suctioning the waste liquid in the light measuring disc.

[0040] The analysis device can not only realize the normal waste suction function through the lifting movement of the waste suction assembly 34, but also reduce the occupation of the waste suction mechanism 3 to the space on the side and top of the light measuring disc mechanism 2, which is convenient for the layout of other mechanisms on the rack and also facilitates the waste suction assembly 34 to avoid other components above the light measuring disc mechanism 2. In addition, the waste suction mechanism 3 and the light measuring disc mechanism 2 are integrated together, which can realize the modular design of both and reduce the difficulty of subsequent debugging of the positions of each mechanism. Moreover, the protruding part on the top of the rack and the light measuring disc mechanism 2 is small, which facilitates the maintenance of the top of the rack and the light measuring disc mechanism 2.

[0041] As shown in Figure 1 The light measuring disc mechanism 2 further comprises a light measuring disc driving assembly 22 for driving the light measuring disc to rotate around its own axis in the bin body 21. The light measuring disc driving assembly 22 is installed below the mounting bottom plate 11. The light measuring disc driving assembly 22 is specifically a driving motor which drives the central shaft of the light measuring disc to rotate through a gear transmission belt mechanism. The light measuring disc driving assembly 22 is installed below the mounting bottom plate 11, which can further make full use of the installation space between the mounting bottom plate 11 and the rack compared with the traditional light measuring disc driving assembly 22 installed below the rack, which is conducive to realizing the compact design of the whole analysis device.

[0042] As shown in Figure 2 and Figure 3 In some embodiments, the mounting bottom plate 11 is provided with a mounting surface for connecting with the mounting bracket 31, and the mounting bracket 31 is located below the mounting surface. Specifically, the mounting bracket 31 is fixedly connected with the mounting bottom plate 11 through a plurality of vertically arranged bolts. In this way, the suspension installation of the whole waste suction mechanism 3 can be realized. In other alternative embodiments, the mounting bottom plate 11 can be further provided with a vertically downwardly bent vertical bending plate, and the mounting bracket 31 is fixedly connected with the vertical bending plate of the mounting bottom plate 11 through a plurality of horizontally arranged bolts.

[0043] AsFigure 2 and Figure 3 As shown, in some embodiments, the mounting bracket 31 includes a top mounting plate 311 and a main mounting plate 312; the top mounting plate 311 is horizontally arranged, and the main mounting plate 312 is vertically arranged. The top surface of the top mounting plate 311 is the mounting surface connecting the mounting bracket 31 and the mounting base plate 11, and the top mounting plate 311 and the mounting base plate 11 are surface-to-surface connected. The main mounting plate 312 is integrally connected below the top mounting plate 311 and arranged perpendicular to the top mounting plate 311. Specifically, the mounting bracket 31 can be formed by bending a sheet metal part. The main mounting plate 312 has a first mounting side and a second mounting side arranged opposite to each other. The first mounting side and the second mounting side are the largest surfaces of the main mounting plate 312, and the area of ​​the first mounting side and the second mounting side is larger than the area of ​​the mounting surface on the top mounting plate 311.

[0044] like Figure 2 and Figure 3As shown, the first installation side of the main installation plate 312 faces the installation space below the bin body 21. The driving member 32 is specifically a motor, which is installed horizontally on the first installation side of the main installation plate 312. The waste liquid suction mechanism 3 further comprises a transmission assembly 35 which is in transmission connection between the driving member 32 and the lifting assembly 33, and which is located on the side of the installation support 31 away from the motor. In some embodiments, the transmission assembly 35 comprises a swing arm 351 fixedly connected with the output shaft of the motor, a linear guide rail 353 fixed on one side of the installation support 31, and a sliding seat 354 slidingly connected with the linear guide rail 353 along the guide direction of the linear guide rail 353. The lifting assembly 33 is fixedly connected with the sliding seat 354, and the sliding seat 354 is provided with a guide groove 3541 located on one side of the swing arm 351, and the end of the swing arm 351 away from the output shaft is provided with a force transmission member 352 extending into the guide groove 3541; when the swing arm 351 swings under the driving action of the motor, the force transmission member 352 moves in the guide groove 3541 to drive the sliding seat 354 and the lifting assembly 33 to move up and down along the guide direction of the linear guide rail 353. In this way, the motor drives the sliding seat 354 and the lifting assembly 33 to move up and down along the guide direction of the linear guide rail 353 by driving the swing arm 351 to swing, which can realize the horizontal installation of the motor on the installation support 31, and compared with the vertical installation of the motor in the conventional waste liquid suction mechanism, the overall height of the waste liquid suction mechanism can be reduced, and the requirement of the installation height of the waste liquid suction mechanism can be reduced; compared with the way of using a worm gear transmission mechanism to realize the lifting of the horizontal motor, the worm gear transmission mechanism with high manufacturing cost is not needed, which is conducive to cost saving, and the guide groove 3541 can limit the lifting movement stroke of the sliding seat 354 and the lifting assembly 33 through the force transmission member 352, and an additional lifting stroke limiting mechanism is not needed, and the structure is simpler. In other alternative embodiments, the transmission assembly 35 can also adopt a worm gear transmission mechanism, as long as the transmission assembly 35 can convert the rotary motion of the horizontal motor shaft into vertical lifting motion.

[0045] As shown in Figure 2 and Figure 3 , the force transmission member 352 is a roller rotatably arranged around its own axis, and the guide groove 3541 is a strip-shaped groove, and the roller and the strip-shaped groove are in rolling cooperation. The force transmission member 352 adopts the form of rolling cooperation between the roller and the strip-shaped groove on the sliding seat 354, which can reduce the friction resistance between the roller and the sliding seat 354, and make the operation of the lifting assembly 33 more smooth.

[0046] As shown in Figure 2 and Figure 3As shown, the lifting assembly 33 comprises a support rod base 331 fixedly connected with the sliding base 354, and a support rod 332 fixed to the support rod base 331 and internally hollow. The waste liquid suction assembly 34 further comprises a cantilever 342 detachably connected to the support rod 332 and extending towards the top of the photodisk, and a liquid guide pipe 343 passing through the inside of the support rod 332; the waste liquid needle 341 is installed below the cantilever 342 and communicates with the liquid guide pipe 343. The lifting assembly 33 further comprises a top cover 333 covering the cantilever 342. The structure of the liquid guide pipe 343 passing through the inside of the support rod 332 is compact in overall structure. Further, the mounting angle of the cantilever 342 on the support rod 332 is adjustable, and cantilevers 342 of different lengths can be detachably connected to the support rod 332, so that waste liquid suction of reaction cups at different positions can be realized, and the versatility of the waste liquid suction mechanism 3 is improved. The part of the top outlet of the waste liquid needle 341 connected with the liquid guide pipe 343 is bent at 90° to reduce the height dimension of the waste liquid needle 341. The lifting assembly 33 further comprises a top cover 333 covering the cantilever 342, which is used to protect the exposed parts of the waste liquid needle 341 and the liquid guide pipe 343 above the cantilever 342.

[0047] In summary, the analysis equipment provided by the present application reduces the occupation of the waste liquid suction mechanism 3 to the space on the side and top of the photodisk mechanism 2 by fixing the mounting bracket 31 of the waste liquid suction mechanism 3 to the mounting bottom plate 11, which facilitates the layout of other mechanisms on the rack and also facilitates the waste liquid suction assembly 34 to avoid other components above the photodisk mechanism 2. In addition, the waste liquid suction mechanism 3 and the photodisk mechanism 2 are integrated together, which can realize the modular design of both, and reduce the debugging difficulty of the positions of subsequent mechanisms.

[0048] Obviously, the above embodiments are only examples for clear illustration, and are not limitations to the embodiments. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
