Description

Technical Field

[0001] The utility model relates to a centrifugal tube plate rack in a laboratory, in particular to a centrifugal tube plate rack capable of fixing centrifugal tubes. Background Art

[0002] The centrifuge tube plate rack is a commonly used experimental equipment in the fields of medicine, biology and scientific research. This centrifuge tube plate rack is provided with a large number of tube holes. The centrifuge tube plate rack is used to place centrifuge tubes for experimental operations. The centrifuge tubes are placed in the tube holes, and then the subsequent experimental operations such as adding samples are carried out with the centrifuge tube plate rack.

[0003] The current problem is that the centrifuge tubes are placed in the tube holes, but the tube holes cannot fix the centrifuge tubes and cannot fix the centrifuge tubes on the centrifuge tube rack. There is a greater risk of falling, and it is easy to accidentally touch and knock over during the experiment, which will lead to sample misalignment, tipping, spilling and contamination. In addition, when liquid mixing steps are required, since the centrifuge tubes are not fixed, it is impossible to turn all the centrifuge tubes on the centrifuge tube rack upside down and mix them at the same time, so each centrifuge tube sample has to be operated separately, which will result in a lot of time and effort. Summary of the invention

[0004] The utility model aims to provide a centrifuge tube plate rack capable of fixing centrifuge tubes. A ratchet piece is arranged in a tube placement hole of the centrifuge tube plate rack. The ratchet piece can clamp and fix the centrifuge tube and prevent the centrifuge tube from tipping over due to being touched by external force.

[0005] In order to achieve the above technical purpose, the utility model adopts the following technical solutions:

[0006] A centrifuge tube plate rack capable of fixing centrifuge tubes, the centrifuge tube plate rack is provided with a plurality of tube placement holes; a plurality of ratchet plates are arranged inside the tube placement holes, all of the ratchet plates are evenly and discretely arranged on the inner wall of the tube placement holes, the tooth tips of the ratchet plates face the inner side of the tube placement holes, and the tooth tips of all the ratchet plates are gathered together.

[0007] Furthermore, the ratchet piece is made of silicone material or microporous plastic material.

[0008] Furthermore, the number of ratchet pieces arranged in the catheter placement hole is 7.

[0009] Furthermore, the ratchet piece in the tube placement hole is arranged at a middle position in the height direction of the tube placement hole.

[0010] Furthermore, the number of tube placement holes arranged on the centrifugal tube plate rack is 12×8.

[0011] Furthermore, the specification of the tube holes in the centrifuge tube plate rack is 1.5ml or 2ml.

[0012] Compared with the prior art, the centrifuge tube plate rack of the utility model has the following beneficial effects: a centrifuge tube filled with a sample liquid is placed in the tube placement hole of the centrifuge tube plate rack of the utility model, and the ratchet piece in the tube placement hole can clamp and fix the centrifuge tube. In this way, during the experimental operation using the centrifuge tube plate rack of the utility model, the centrifuge tube will not be dislocated, overturned, splashed or contaminated due to a slight external force, thereby ensuring the safety and stability of the experimental operation process. Moreover, when it is necessary to perform an inversion and mixing operation on all the centrifuge tubes on the centrifuge tube plate rack, the entire centrifuge tube plate rack can be operated to perform the inversion and mixing operation, without having to perform an individual operation on each centrifuge tube sample, thereby greatly improving work efficiency and saving time and labor costs.

[0015] The utility model is further described below with specific embodiments:

[0016] See also Figure 1 The present embodiment provides a centrifuge tube plate rack 1. Those skilled in the art will appreciate that a plurality of tube placement holes 2 are provided on the centrifuge tube plate rack 1, and the tube placement holes 2 are used to place centrifuge tubes. The centrifuge tube plate rack 1 is used to temporarily store centrifuge tube samples and facilitate subsequent unified sample processing, such as opening the cover to add samples, inverting and mixing, and the like. The centrifuge tube plate rack 1 in the present embodiment has a specific number of 12×8 tube placement holes 2 provided thereon.

[0017] The centrifuge tube plate rack of this embodiment has a main innovation in the internal structure design of the tube placement hole 2 .

[0018] Specifically, see Figure 2 ,

[0019] A certain number of ratchet pieces 3 are arranged inside the catheter hole 2, the root of the ratchet piece 3 is fixedly connected to the inner wall of the catheter hole 2, and the tip of the ratchet piece 3 faces the inside of the catheter hole 2. All the ratchet pieces 3 are evenly and discretely arranged on the inner wall of the catheter hole 2 along the circumferential direction, and all the ratchet pieces 3 are located at the same height position in the catheter hole 2, and the tip of the teeth of all the ratchet pieces 3 can be gathered together in the middle of the catheter hole 2.

[0020] It should be noted that the ratchet pieces 3 are made of soft elastic material. In this embodiment, the ratchet pieces 3 are made of silicone material, but in other embodiments, microporous plastic material can also be used.

[0021] The number of ratchet pieces 3 provided in the catheter placement hole 2 can be determined according to actual conditions, and the present invention has no particular limitation on this. In this embodiment, the number of ratchet pieces 3 provided in the catheter placement hole 2 is 7.

[0022] When using the centrifuge tube plate rack of this embodiment, the centrifuge tube is inserted into the tube hole 2, and the ratchet pieces 3 in the tube hole 2 are pressed against the centrifuge tube under the action of their own elastic force, and all the ratchet pieces 3 are pressed against the centrifuge tube at the same time, thereby forming a clamping posture for the centrifuge tube. Under the clamping action of all the ratchet pieces 3, the centrifuge tube is fixed in the tube hole 2, so that the situation of "the centrifuge tube being touched and tipped over" will not easily occur.

[0023] In this embodiment, 7 ratchet pieces 3 are arranged in the middle of the height direction of the tube placement hole 2. Specifically, the position of the ratchet piece 3 in the tube placement hole 2 should not be too low or too high. If the position is too low, the ratchet piece 3 cannot fix the centrifuge tube. If the position is too high, the ratchet piece 3 will fix the centrifuge tube too firmly, which is not conducive to pulling the centrifuge tube out of the tube placement hole 2. Therefore, the position of the ratchet piece 3 is set in the middle of the height direction of the tube placement hole 2, and the clamping force of the ratchet piece 3 on the centrifuge tube is relatively moderate, and the situation of "the ratchet piece 3 cannot fix the centrifuge tube" and "the ratchet piece 3 fixes the centrifuge tube too firmly" will not occur.

[0024] The specification of the tube hole 2 in the centrifuge tube plate rack 1 can be set to 1.5ml or 2ml as needed.

[0025] In the process of conducting experimental operations using the centrifuge tube plate rack of this embodiment, since the centrifuge tubes on the centrifuge tube plate rack 1 are clamped and fixed by the ratchet pieces 3 in the tube holes 2, that is, the centrifuge tubes are fixed on the centrifuge tube plate rack 1, the centrifuge tubes will not be dislocated, overturned, splashed or contaminated due to slight external force, thereby ensuring the safety and stability of the experimental operation process.

[0026] In addition, when all the centrifuge tubes on the centrifuge tube plate rack 1 need to be inverted and mixed, the entire centrifuge tube plate rack 1 can be operated to perform the inversion and mixing operation without having to perform the operation on each centrifuge tube sample separately, thereby greatly improving work efficiency and saving time and labor costs.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
