[0029] Each of the circulation installation jigs 3 of the present invention moves on the runway-shaped track 2, and the space occupied by the runway-shaped track 2 is smaller than that of the circular turntable, so that the circulation device of the immunoassay analyzer of the present invention has the advantage of occupying less space. In addition, the present invention also has a circulation positioning mechanism that cooperates with the movable positioning of each of the circulation installation jigs 3, so that the circulation installation jig 3 can be positioned at the required workstation through the circulation positioning mechanism, avoiding the flow installation jig 3 being unable to accurately move to the required workstation due to the speed difference between the flow installation jig 3 on the straight section 21 and the arc section 22 of the runway-shaped track 2.

[0030] Cooperate Figure 1 and Figure 2 As shown, in the embodiment of the present utility model, the flexible transmission device 4 adopts a synchronous belt transmission device. It should be noted that the flexible transmission device 4 can also adopt a chain transmission device, and both the chain transmission device and the synchronous belt transmission device can drive the flow installation fixture 3 to move along the runway track 2.

[0031] In an embodiment of the utility model, the circulation installation jig 3 is provided with an inner guide wheel 31 and an outer guide wheel 32 respectively slidingly connected with the inner and outer sides of the runway-type track 2, so that the circulation installation jig 3 moves more smoothly. Wherein, the circulation installation jig 3 may include a jig body 301 and a jig slide 302 slidingly connected with the jig body 301, a telescopic spring 303 is provided between the jig slide 302 and the jig body 301, the jig body 301 and the jig slide 302 are respectively connected with the inner guide wheel 31 and the outer guide wheel 32, and the elastic force of the telescopic spring 303 can drive the inner guide wheel 31 and the outer guide wheel 32 to always hold the inner and outer sides of the runway-type track 2 respectively, so that the movement of the circulation installation jig 3 is always kept stable. The inner guide wheel 31 and the outer guide wheel 32 may both have annular guide grooves that match the side walls of the runway-type track 2, thereby preventing the inner guide wheel 31 and the outer guide wheel 32 from escaping from the runway-type track 2, thereby allowing the flow installation fixture 3 to be more stably matched with the runway-type track 2.

[0032] In an embodiment of the utility model, the circulation installation fixture 3 is provided with a reaction cup installation hole 33, and the reaction cup installation hole 33 can be set on the fixture body 301 of the circulation installation fixture 3.

[0033] In the embodiment of the utility model, the circulation installation jig 3 is provided with a jig positioning part 34, which can be arranged on the jig body 301 of the circulation installation jig 3, and the jig positioning part 34 has a positioning slot 341; and the circulation positioning mechanism includes at least two circulation positioning devices 5, the circulation positioning device 5 includes a positioning shaft 51, a positioning drive motor 52 driving the positioning shaft 51 to rotate, and at least one positioning rod 53 arranged on the positioning shaft 51 and intersecting with the positioning shaft 51, and the positioning rod 53 is movably inserted into the positioning slot 341 of the jig positioning part 34 of the circulation installation jig 3.

Correspondingly, the positioning shaft 51 and the positioning rod 53 of the circulation positioning device 5 are arranged perpendicular to each other, so that the rotation of the positioning shaft 51 can control the positioning rod 53 to enter and exit the positioning slot 341. The jig positioning portion 34 of the circulation installation jig 3 also has two inclined guide surfaces 342 respectively connected to the two sides of the positioning slot 341.
