The first part is the testing items, which include sensory testing of food, quality testing of milk and dairy products, and quality testing of beverage products. When testing some fluid foods, it is necessary to use equipment to centrifuge the food. In the existing technology, the sample fixation effect is not good, and it is inconvenient to place and pick up the sample. The separation efficiency is low, and the existing centrifuge components are large and inconvenient to move, resulting in poor flexibility. Summary of the Invention

[0003] The purpose of this invention is to provide a food testing centrifuge assembly to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a food testing centrifuge assembly, comprising a movable base, four support columns fixedly connected to the top of the movable base, a table fixedly connected to the top of the support columns, a motor fixedly connected to the bottom of the table, a turntable fixedly connected to the output end of the motor through the table, a placement box fixedly connected to the top of the turntable, a fixed seat fixedly connected inside the placement box, an installation groove provided on the front side of the fixed seat, a threaded rod rotatably connected through the installation groove, four partitions rotatably connected through the threaded rod, and the partitions fixedly connected to the inner wall of the installation groove, clamps provided on both sides of the four partitions, the clamps penetrating and threadedly connected to the threaded rod, telescopic grooves provided on adjacent sides of two clamps, multiple springs fixedly connected in the telescopic grooves, telescopic blocks fixedly connected to the outward ends of the springs, and sleeves fixedly connected to the outer sides of the telescopic blocks, placement grooves provided on both sides of the bottom of the movable base, lifting assemblies provided in both placement grooves, and two universal wheels connected to the bottom of the lifting assemblies.

[0005] By adopting the above technical solution, when the threaded rod rotates, the clamps on both sides of the partition will move relative to each other, thereby driving the two clamps to move relative to each other, clamping and fixing the sample tube on both sides. The elastic force of the spring can prevent the clamps from excessively squeezing the sample tube and causing damage.

[0006] As a further description of the above technical solution: the lifting assembly includes cylinders, the tops of the two cylinders are fixedly connected to the placement groove, the output ends of the two cylinders are fixedly connected to the lifting seat, the bottom of the lifting seat is provided with a limit groove, a plurality of dampers are fixedly connected in the limit groove, the bottom of the dampers is fixedly connected to a shock absorber seat, and both sides of the bottom of the shock absorber seat are fixedly connected to casters.

[0007] By adopting the above technical solution, the lifting component can drive the casters to lift and lower, so that the mobile seat can directly contact the ground, allowing the centrifugal component to be stably placed on the ground and ensuring the stability of the mobile seat after it has moved.

[0008] As a further description of the above technical solution: the top of the placement box is rotatably connected to a top cover.

[0009] By adopting the above technical solution, a switch lock is installed on the top cover, which makes it easy to open and close the top cover.

[0010] As a further description of the above technical solution: the telescopic block is disposed in the telescopic groove, and the outside of the telescopic block is slidably connected to the inner wall of the telescopic groove.

[0011] By adopting the above technical solution, the telescopic block can extend and retract within the telescopic groove.

[0012] As a further description of the above technical solution: the left side of the threaded rod is fixedly connected to a knob through the placement box, and the knob is located on the outside of the placement box. The knob has evenly distributed through holes through its outer side, and a limit screw is installed in the through hole.

[0013] By adopting the above technical solution, the threaded rod can be rotated by turning the knob.

[0014] As a further description of the above technical solution: guide columns are fixedly connected to both sides of the placement slot, and the guide columns are slidably connected to both sides of the lifting seat.

[0015] By adopting the above technical solution, grooves are opened on both sides of the lifting seat, and the lifting seat can slide along the outside of the guide column through the grooves on both sides.

[0016] As a further description of the above technical solution: a sample tube is disposed between the two jackets.

[0017] The above technical solution is used to place the sample to be tested.

[0018] As a further description of the above technical solution: the shock absorber seat is disposed in the limiting groove, and the outside of the shock absorber seat is slidably connected to the inner wall of the limiting groove.

[0019] By adopting the above technical solution, the shock absorber seat can move within the limiting groove.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This food testing centrifuge assembly, by placing a sample tube containing the sample between two clamps in the placement box, and then rotating the knob to drive the threaded rod to rotate, and since the threads on the threaded rods on both sides of the partition are opposite, when the threaded rod rotates, the clamps on both sides of the partition will move relative to each other, thereby driving the two clamps to move relative to each other, clamping and fixing the sample tube on both sides. The elastic force of the spring can prevent the clamps from excessively squeezing the sample tube and causing damage. After the sample tube is fixed, the limiting screw is inserted through the corresponding through hole on the knob into the positioning groove on the left side of the placement box to limit the knob and prevent the threaded rod from rotating during centrifugation, ensuring that the clamp position is fixed, thereby ensuring the stability of the sample tube. When the knob is rotated in the opposite direction, the threaded rod can drive the two clamps and the clamps to move in opposite directions, making it easy to remove the sample tube, thereby realizing the rapid fixing of multiple sample tubes and enabling the simultaneous centrifugation of multiple different samples, improving work efficiency.

[0021] When the centrifugal assembly needs to be moved, the cylinder in the lifting assembly is activated. The cylinder output pushes the lifting seat downwards, which in turn moves the bottom shock absorber and casters downwards until the casters contact the ground and lift the moving seat, allowing the entire centrifugal assembly to move. Once the desired position is reached, the cylinder is activated again, causing the cylinder output to retract. The lifting seat then moves the shock absorber and casters upwards, retracting the casters. At this point, the moving seat is in direct contact with the ground, ensuring the centrifugal assembly is stably placed on the ground and guaranteeing stability after movement.
