Table type milk fat centrifugal machine

Abstract

The utility model relates to the technical field of test equipment, and particularly discloses a table type milk fat centrifugal machine which comprises a frame body, a centrifugal base arranged on the inner side of the frame body, placing holes evenly distributed in the circumference of the centrifugal base, a rotating shaft fixed to the lower end of the centrifugal base, a motor installed at the lower end of the rotating shaft and a cover plate arranged at the upper end of the frame body. And a fixing mechanism for pressing and limiting the placed test tube is arranged on the centrifugal seat. Through the arrangement of a fixing mechanism, a rotating disc and a centrifugal seat rotate relatively, a limiting pin gradually enters the bottom of a crescent groove in the rotating disc under pushing of a first spring, meanwhile, the upper end face of a test tube in a placement hole pushes the inclined face of a pressing plate on the lower side of the rotating disc, and the pressing plate upwards extrudes a second spring; and when the centrifugal seat rotates along with the rotating shaft, the limiting pin stirs the rotating disc to rotate along with the centrifugal seat, so that the test tube is always in a pressed state in the rotating process, and the stability of the centrifugal process is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of test equipment, in particular to a desktop cream centrifuge. Background Art

[0002] Centrifuges are instruments that use centrifugal force to separate liquids from solid particles or liquids from liquids. They are widely used in chemistry, chemical engineering, medicine, food, and pharmaceuticals. Current centrifuges primarily place test tubes in a well and then spin them at high speed through a motor. These centrifuges lack effective clamping and limiting of the test tubes during operation, making them prone to tube shaking and compromising centrifugal stability. Utility Model Content

[0003] The purpose of the present utility model is to provide a desktop cream centrifuge in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] The centrifuge is equipped with a plurality of control plates, a bottom plate and a bottom plate, and a plurality of control plates are installed on the top plate of the centrifuge, the rotation of the plurality of control plates is carried out, and the plurality of control plates are installed on the bottom plate of the centrifuge.

[0006] It is further configured that the limit pin is slidably connected to the centrifugal seat, the limit pin is provided at least at four locations, and the limit pin is slidably connected to the crescent groove.

[0007] Further configuration: a handle is provided at the center of the rotating disk, and a handle is fixed on the centrifugal seat.

[0008] Further configuration: a label frame is provided on the inner wall of the centrifugal seat at a position corresponding to the placement hole.

[0009] It is further arranged that the area of the holding plate is larger than the area of the placement hole, and the holding plate is slidably connected to the sinking platform of the rotating disk.

[0010] It is further configured that the rotating disk and the centrifugal seat are in a conical shape, and the rotating disk fits in the conical surface of the centrifugal seat.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] By setting the fixing mechanism, the rotating disk and the centrifugal seat are rotated relative to each other, so that the limit pin gradually enters the bottom of the crescent groove on the rotating disk under the push of the first spring, and at the same time, the upper end surface of the test tube placed in the hole pushes the inclined surface of the holding plate on the lower side of the rotating disk, and the holding plate presses the second spring upward until the holding plate completely holds the test tube in a limited position, so that when the centrifugal seat rotates with the rotating shaft, the limit pin drives the rotating disk to rotate as a whole with the centrifugal seat, so that the test tube is always in a pressed state during the rotation process, thereby ensuring the stability of the centrifugal process.
