Reactant rotary mixing device used for chemical luminescence immunoassay analyzer

The utility model relates to a reactant rotary mixing device used for a chemical luminescence immunoassay analyzer. The reactant rotary mixing device comprises a cup frame mechanism, a chain, rack and a gear, wherein the rack and the gear are corresponding to each other, the cup frame mechanism comprises a reaction cup and a cup frame; the gear is arranged on the bottom of the cup frame and is connected with the chain; the chain drives the gear and the cup frame mechanism to move; when the gear is engaged with the rack, the rack slides and drives the gear to rotate. The reactant rotary mixing device used for the chemical luminescence immunoassay analyzer, which adopts the structure, is simple in structure, and can be operated by staff conveniently; the chain can drive the cup frame mechanism to advance by a single step, and when the cup frame mechanism moves to the rack for driving the gear to rotate, the cup frame mechanism starts rotating; in a whole incubation reaction process, reactants are in a uniform m
