The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] See also Figures 1 to 6 The present invention provides a refrigerated centrifuge, comprising a round block 1, a box cover 2, a box body 3 and an auxiliary mechanism. The round block 1 is provided with a sealing cover 4 through a thread. The upper end surface of the round block 1 has a plurality of test tube holes 5. The round block 1 has a connecting cavity 6. A vertical pipe 7 is provided below the round block 1. The outer side of the vertical pipe 7 has a plurality of air inlet holes 8. A motor 9 is provided below the box body 3. An extension rod 10 is provided on the inner side of the box body 3. A collar 11 is provided at one end of the extension rod 10. The inner side of the collar 11 has an air collecting cavity 12. An air inlet pipe 13 is provided at one end of the collar 11, and one end of the air inlet pipe 13 is connected to a refrigerator 14. The vertical pipe 7 is rotatably connected to the collar 11 and is located in the collar 11, and the round block 1 is located in the box body 3. The vertical pipe 7 is arranged at the output end of the motor 9, the box cover 2 is threadedly connected to the box body 3 and covered on the top of the box body 3. By opening the box cover 2, the test tube that needs to be refrigerated and centrifuged is placed in the test tube hole 5, and then the sealing cover 4 is threadedly covered on the round block 1 to prevent the test tube from popping out, and the box cover 2 is covered with the box body 3, and then the motor 9 is started to drive the vertical pipe 7 to rotate, and the vertical pipe 7 drives the round block 1 to rotate as a whole. The round block 1 centrifuges its test tube, and at the same time, the cold air is introduced into the air inlet pipe 13 through the refrigerator 14, and the cold air is discharged into the connecting cavity 6 through the air collecting cavity 12, the air inlet hole 8 and the vertical pipe 7, thereby freezing the test tube in the test tube hole 5.

[0022] According to this specific embodiment, the auxiliary mechanism includes a bottom guide groove 15, a bottom support 16, a side guide groove 17, a side support 18 and a support plate 19, wherein a plurality of first balls 20 are provided in the bottom guide groove 15, a plurality of second balls 21 are provided in the side guide groove 17, the bottom guide groove 15 is provided on the support plate 19, the bottom support 16 is provided below the round block 1, the bottom support 16 is slidably connected to the bottom guide groove 15 and covers the bottom guide groove 15, the side guide groove 17 is provided on the inner side of the box body 3, the side support 18 is provided on the outer side of the round block 1, and the side support 18 is provided on the outer side of the round block 1. The side guide groove 17 is slidably connected and covers the side guide groove 17. The support plate 19 is arranged on the inner side of the box body 3 and is also sleeved on the vertical tube 7. By arranging force-bearing components on the bottom and outer side of the round block 1, the stability of the round block 1 during rotation can be improved under the action of the first ball 20 and the second ball 21. The first ball 20 and the second ball 21 can convert sliding friction into rolling friction, thereby significantly reducing friction. In this way, the technical problem that the large centrifugal force generated when the round block rotates cannot be guaranteed by the annular slider alone to ensure the stable rotation of the round block, thereby reducing the centrifugal effect on the test tube, is solved.

[0023] The bottom support 16 also abuts against the first balls 20 , and the side support 18 also abuts against the second balls 21 .

[0024] Secondly, the plurality of test tube holes 5, the vertical tube 7 and the connecting cavity 6 are in a communicating state, and this design facilitates the entry of cold air.

[0025] Again, the plurality of air inlet holes 8, the air collecting cavity 12 and the air inlet pipe 13 are in a connected state, and this design facilitates the entry of cold air.

[0026] In addition, the refrigerated centrifuge also includes a support tube 22, a plurality of support legs 23 and a fixed ring 24. The support tube 22 is fixedly connected to the box body 3 and is located at the inner bottom of the box body 3. It is also sleeved on the outside of the vertical pipe 7. The plurality of support legs 23 are respectively fixedly connected to the fixed ring 24 and are located on the outside of the fixed ring 24 and are tilted. The fixed ring 24 is fixedly connected to the box body 3 and is located below the box body 3. The support tube 22 can facilitate the improvement of the stability of the vertical pipe 7 during rotation. The support legs 23 and the fixed ring 24 can facilitate the support of the box body 3. At the same time, the tilted setting of the support legs 23 can facilitate the improvement of the overall stability of the device.

[0027] When the utility model is used to support the round block 1, first, the bottom support 16 slides on the bottom guide groove 15, and at the same time, the first ball 20 ensures the stability and smoothness of the bottom support 16 when sliding. Secondly, the side support 18 slides on the side guide groove 17, and the second ball 21 ensures the stability and smoothness of the side support 18 when sliding. Therefore, with the cooperation of the above two groups of supporting components, the round block 1 can be ensured to rotate more stably. In this way, the technical problem that the large centrifugal force generated when the round block rotates cannot be guaranteed by the annular slider alone, thereby reducing the centrifugal effect on the test tube is solved.

[0028] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
