[0027] The following further explains and illustrates the present invention in conjunction with specific embodiments.

[0028] As Figures 1-3 shown, a multi-needle sampling arm structure provided in this embodiment includes: a sampling arm main body 10, a reagent needle group, and a driving mechanism group. The reagent needle group includes a plurality of adjacent mounting seats 20; the reagent needles 21 are vertically arranged on the mounting seats 20; the mounting seats 20 are movably arranged up and down on the main body 10; the driving mechanism group includes a plurality of adjacent driving mechanisms 30; a plurality of the driving mechanisms 30 are respectively connected to a plurality of mounting seats 20 through a plurality of intermediate connecting rods 35 for driving the mounting seats 20 and the reagent needles 21 to move up and down respectively; the shapes of the plurality of intermediate connecting rods 35 are different. In this application, the intermediate connecting rod 35 is a strip structure.

[0029] In this application, the mounting seats 20 and the driving mechanisms 30 are arranged in groups or zones, and the sampling needle modules are no longer unified. The positional relationships between the driving mechanisms 30 and the mounting seats 20 in a plurality of sampling needle modules are also different, and thus the shapes of the intermediate connecting rods 35 are also different to adapt to different positions and connection relationships. Therefore, the structure of this application is more compact and occupies less space.

[0030] Among them, at least one of the intermediate connecting rods 35 is an L-shaped rod, a Z-shaped rod, or an N-shaped rod, so as to adapt to a specific positional relationship between a group of mounting seats 20 and driving mechanisms 30.

[0031] Further, the driving mechanism 30 is a belt drive mechanism, including: a driving motor 31, a driving wheel 32, a driven wheel 33, and a transmission belt 34. The transmission belt 34 is sleeved on the driving wheel 32 and the driven wheel 33, and the driving motor 31 drives the transmission belt 34 to rotate reciprocally through the driving wheel 32. One end of the intermediate connecting rod 35 is fixedly connected to the transmission belt 34, and the other end of the intermediate connecting rod 35 is connected to the mounting seat 20.

[0032] Similarly, the driving mechanism 30 can also be a chain drive mechanism, including a driving motor 31, a driving sprocket, a driven sprocket, and a chain. One end of the intermediate connecting rod 35 is fixedly connected to the chain, and the other end of the intermediate connecting rod 35 is connected to the mounting seat 20.

See Figure 4 As shown, correspondingly, the support frame 11 is T-shaped, and the three passive wheels 33 are rotatably provided on the three ends of the support frame 11.

[0035] When the drive mechanism group includes 4 drive mechanisms 30, preferably, the 4 drive mechanisms 30 are arranged in a cross shape. See Figure 5 As shown, the support frame 11 is cross-shaped, and the four passive wheels 33 or passive sprockets are rotatably provided on the four ends of the support frame 11.

[0036] Alternatively, the drive mechanism 30 can also be a telescopic mechanism, such as a cylinder, an oil cylinder or an electric telescopic rod, etc. The telescopic mechanism includes: a main body and a telescopic part.

[0040] The second aspect of this application discloses a fully automatic chemiluminescence immunoassay analyzer with the above multi-needle sampling arm structure.

[0041] The multi-needle sampling arm structure provided by the present invention arranges the mounting base 20 and the driving mechanism 30 in groups or partitions. The sampling needle modules are no longer unified, and the positional relationships between the driving mechanisms 30 and the mounting bases 20 in several sampling needle modules are also different, and the shapes of the intermediate connecting rods 35 are different to adapt to different positions and connection relationships. Thus, the structure of the present application is more compact and occupies less space.
