A laboratory mixing device

Abstract

The utility model relates to medical instrument technical field, specifically disclose a mixing and shaking device for clinical laboratory, including the placing box, still include: detection mechanism, detection mechanism sets up inside the placing box, and detection mechanism detects the total weight and total quantity of test tube, rotating mechanism, rotating mechanism sets up one side at detection mechanism, and rotating mechanism drives test tube to rotate, the utility model discloses through adjusting mechanism, and the control center passes through electric push rod and adjusts the position of sliding block on the variable resistor, and the power frequency of fixed motor is changed in combination frequency converter, and the rotational speed is accurately adjusted, simultaneously, and the magnetic repulsion of first permanent magnet and second permanent magnet changes with load (the permanent magnet spacing reduces when weight increases, and the repulsion increases), realize the self -adaptation compensation of torque, this "rotational speed electric regulation + torque magnetic repulsion compensation" dual mechanism can avoid the motor overload when heavy load, and can prevent the sample splash when light load.
