[0023] Embodiment 1

[0024] The utility model provides a movable bracket 3 at the bottom of the centrifuge tube rack, so that the staff can drag the centrifuge tube rack. The perforated discs 2 can move on the support column 1, and the distance between the perforated discs 2 can be adjusted to adapt to test tubes of different sizes.

[0025] like Figure 1-2 As shown, a rollable centrifuge tube rack includes a support column 1 and at least two perforated discs 2, and the perforated discs 2 are movably mounted on the support column 1. A movable bracket 3 is arranged at the bottom of the support column 1. The movable bracket 3 includes at least three support rods 31 and a rolling assembly 32 rotatably connected under each support rod 31.

[0026] The specific rotational connection method between the rolling component 32 and the lower end of the support rod 31 can be: a connecting block is set on the top of the rolling component 32, and the specific structure is cylindrical. The lower end of the support rod 31 is provided with an installation groove for accommodating the connecting block, and the specific structure is cylindrical. The connecting block can rotate horizontally in the installation groove.

[0027] Further, the rolling assembly 32 includes a connecting portion 321 and a roller 322 movably mounted on the connecting portion 321. The connecting portion 321 is provided with an abutment assembly 323 that hinders the rotation of the roller 322. Further, the abutment assembly 323 includes an abutment rod 3231 and an elastic member 3232. The abutment rod 3231 is movably connected to the connecting portion 321 up and down through the elastic member 3232. Further, arc grooves 3221 that are engaged with the abutment rod 3231 are equidistantly arranged on the outer side of the roller 322. One end of the abutment rod 3231 that is engaged with the arc groove 3221 is a spherical surface. The arc groove 3221 and the spherical surface at one end of the abutment rod 3231 can slide relative to each other, and can effectively hinder the rotation of the roller 322 without being locked with each other. It is prevented that the centrifuge tube rack moves easily when subjected to a slight external force.

[0028] Furthermore, a connecting groove for accommodating the abutting assembly 323 is formed at the bottom of the connecting portion 321 .

[0029] like Figure 3 As shown, further, at least one vertical sliding groove 11 is provided on the outer side of the support column 1, and the punching disc 2 is movably mounted on the support column 1 through the vertical sliding groove 11. A plurality of annular sliding grooves 12 are arranged equidistantly from top to bottom on the outer side of the vertical sliding groove 11, and the punching disc 2 is clamped on the support column 1 through the annular sliding grooves 12.

[0030] like Figure 4 As shown, further, a center hole 21 is provided at the center of the perforated disc 2, and the perforated disc 2 is sleeved on the support column 1 through the center hole 21. At least one clamping block 22 is provided on the inner wall of the center hole 21 to be clamped with the annular groove 12. Further, a plurality of mounting holes with different radii are provided on the perforated disc 2 for placing test tubes of different sizes.

[0031] Working principle:

[0032] The operator drags the centrifuge tube rack, and the mobile bracket 3 at the bottom drives the whole to move. In this process, the roller 322 rotates, and the abutment rod 3231 located above the roller 322 continuously moves up and down, and continuously engages and separates with the arc groove 3221. When the operator stops dragging the centrifuge tube rack, the abutment rod 3231 engages with the arc groove 3221 to prevent the roller 322 from rotating. This prevents the centrifuge tube rack from constantly shifting due to inertia.

[0033] Adjust the distance between each punching disc 2: rotate the punching disc 2 to move the block 22 from the annular slide groove 12 to the vertical slide groove 11, release the fixation, and thus the punching disc 2 can move on the support column 1. Move the punching disc 2 up and down, adjust it to a suitable height, and then rotate the punching disc 2 again to move the block 22 from the vertical slide groove 11 to the annular slide groove 12, and fix the punching disc 2 at a suitable height. Other punching discs 2 can be adjusted in this way.
