[0002] The tripod centrifuge is a common laboratory equipment, which is widely used in the fields of chemistry, physics, biology and the like, and is used for separating substances or solutions with different densities. The main feature of the tripod centrifuge is the form of its support structure. The base of the tripod centrifuge is usually composed of three support legs, and thus is called “tripod”.

[0003] In the prior art, the tripod centrifuge needs to be placed on a horizontal flat ground to ensure that the three support legs are located on the same horizontal plane and the entire centrifuge body is in a vertical state. Once one of the support legs is not on the same horizontal plane, the entire centrifuge body will be in an inclined state, and the centrifuged material is easy to splash out. SUMMARY

[0005] In a first aspect, a tripod centrifuge is provided, which includes:

[0006] A loading frame, in which a limiting space for placing a centrifuge body is present;

[0007] A plurality of support structures, which are arranged around the loading frame, and include:

[0008] A base;

[0009] A hinge, which is hinged to the loading frame;

[0010] A lifting cylinder, which is connected to the hinge, and is liftable on the base.

[0011] In some embodiments, the support structure further includes a screw rod and a driving structure.

[0012] The driving structure is arranged on the base, the screw rod is rotationally connected to the base, the driving structure is used to drive the screw rod to rotate, and the screw rod is threadedly connected to the lifting cylinder.

[0013] In some embodiments, the driving structure includes a motor, an output gear and a driving gear.

[0014] The motor is arranged on the base, the output gear is connected with the motor output end, the driving gear is connected with the screw rod, and the output gear is used to drive the driving gear.

[0015] In some embodiments, the driving structure further comprises a first gear and a second gear.

[0016] The first gear and the second gear are both rotationally connected to the base, the first gear is connected with the second gear, the second gear is engaged with the driving gear, and the first gear is engaged with the output gear.

[0017] In some embodiments, the hinge comprises a telescopic end and a fixed end.

[0018] The telescopic end is hingedly connected to the loading frame, the fixed end is connected to the lifting cylinder, and the telescopic end is slidingly connected in the fixed end.

[0019] In some embodiments, the hinge further comprises a hydraulic rod.

[0020] The two ends of the hydraulic rod are connected with the telescopic end and the fixed end respectively.

[0021] The embodiments of the present application provide a three-legged centrifuge. By adjusting the height of the lifting cylinder on the base, the height of one side of the loading frame is controlled, so that the centrifuge body remains horizontal when the centrifuge is placed on a horizontal ground with a height difference. Therefore, the height of one side of the centrifuge body is adjusted by the lifting cylinder, and the centrifuge is placed on two horizontal surfaces with a height difference.
