Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube rack technology, and more specifically, to a centrifuge tube rack for preprocessing biological detection samples. Background Technology

[0002] In biological experiments, a crucial step is the centrifugation of sample solutions. Currently, the commonly used centrifugation method in laboratories is to place the centrifuge tubes containing the sample solution directly onto a centrifuge rack and then place them together on a shaker for vortexing.

[0003] Among them, the patent with announcement number CN219898237U discloses a fixed centrifuge tube rack, including a centrifuge tube rack fixing plate and a tube rack assembly connected to the centrifuge tube rack fixing plate for placing centrifuge tubes; the tube rack assembly includes a centrifuge tube rack upper plate, a centrifuge tube rack middle plate and a centrifuge tube rack bottom plate, the centrifuge tube rack upper plate and the centrifuge tube rack middle plate are respectively provided with centrifuge tube rack upper hole and centrifuge tube rack middle hole, and the centrifuge tube rack middle plate is movably connected to the centrifuge tube rack fixing plate to realize the movement of the centrifuge tube rack middle plate on the plane; When in use, this structure fixes the centrifuge tubes by misaligning the upper and middle holes of the centrifuge tube rack. A washer is placed around each tube hole to effectively prevent the centrifuge tubes from rotating. However, a single washer cannot accommodate test tubes of different sizes, and the addition of an extra spring makes the structure itself relatively complex and its practicality low. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a centrifuge tube rack for preprocessing biological detection samples, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a centrifuge tube rack for preprocessing biological detection samples, including a support plate, wherein a cavity is formed on the support plate, and a plurality of constraint tubes for placing test tubes are distributed on the cavity; Each of the multiple constraint tubes has an elastic ring at one end, and each elastic ring has several abutment balls distributed on its inner wall for positioning the test tube. A constraint sleeve is fixedly provided at the top of the constraint tube, and the constraint sleeve wraps around the outside of the elastic ring. Optionally, in a possible implementation, a plurality of limiting oblique holes are formed on the inner wall of the cavity, and the plurality of limiting oblique holes are distributed circumferentially along the axis of the cavity on the inner wall of the cavity. The plurality of constraint tubes are respectively located in the corresponding limiting oblique holes. The limiting oblique holes are inserted into the constraint tubes. A counterweight is provided at the bottom of the inner wall of the cavity. The counterweight is mounted on the support plate by bolts. A column is provided at the bottom of the support plate. The column passes through the support plate and is threadedly connected to the counterweight. The technical effects and advantages of this utility model are as follows: By using the corresponding combination of various structures, compared with the existing technology, the overall design is simple and the structure is reasonable. The constraint tube forms a wrap-around protection and positioning function for the test tube. When the test tube is placed inside the constraint tube, each contact ball contacts the outside of the test tube. After the elastic ring is deformed by force, it resets and clamps the outside of the test tube, ensuring the stability of the test tube placed inside the constraint tube and also accommodating test tubes of different sizes. Furthermore, the setting of the limiting oblique hole facilitates the positioning of the constraint tube on the support plate, further ensuring the stability of the test tube placement.

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] As attached Figures 1-4The centrifuge tube rack for biological sample pretreatment shown in the figure, through the corresponding cooperation of various structures, forms a wrap-around protection and positioning function for the test tubes through the constraint tube 3. At the same time, when the test tube is placed inside the constraint tube 3, each abutment ball 6 abuts against the outside of the test tube. After the elastic ring 5 is deformed by force, it resets and clamps the outside of the test tube, ensuring the stability of the test tube placed inside the constraint tube 3. It can also adapt to test tubes of different sizes. The specific structural settings are as follows. Each of the multiple constraint tubes 3 has an elastic ring 5 at one end, and each elastic ring 5 has several abutment balls 6 distributed on its inner wall for positioning the test tube. A constraint sleeve 4 is fixedly installed at the top of the constraint tube 3, and the constraint sleeve 4 wraps around the outside of the elastic ring 5.

[0014] Specifically, as shown in the attached document Figure 1 , 2 As shown in Figures 3 and 4, when supporting the test tubes, each test tube can be placed inside the corresponding constraint tube 3. The constraint tube 3 forms a wrap-around protection and positioning function for the test tubes. At the same time, when the test tubes are placed inside the constraint tube 3, each abutting ball 6 abuts against the outside of the test tube. After the elastic ring 5 is deformed by force, it resets and clamps the outside of the test tube, ensuring the stability of the test tubes placed inside the constraint tube 3 and also accommodating test tubes of different sizes. A number of limiting inclined holes 7 are provided on the inner wall of the cavity 2. The multiple limiting inclined holes 7 are distributed around the circumference of the axis of the cavity 2 on the inner wall of the cavity 2. Multiple constraint tubes 3 are located in the corresponding limiting inclined holes 7. The limiting inclined holes 7 are inserted into the constraint tubes 3. A counterweight 8 is provided at the bottom of the inner wall of the cavity 2. The counterweight 8 is installed on the support plate 1 by bolts. A column 9 is provided at the bottom of the support plate 1. The column 9 passes through the support plate 1 and is threadedly connected to the counterweight 8. Specifically, as shown in the attached document Figure 1 , 2 As shown in Figure 3, the setting of the limiting oblique hole 7 facilitates the installation and positioning of the constraint tube 3 on the support plate 1, and also facilitates the removal of the constraint tube 3 from the support plate 1. At the same time, the counterweight block 8 and the column 9 facilitate the counterweighting and positioning of the support plate 1, ensuring the stability of the support plate 1. Furthermore, it can be seen that the limiting oblique hole 7 is set at an angle downwards, and the limiting oblique hole 7 positions the constraint tube 3. The angled setting increases the contact area between the constraint tube 3 and the inner wall of the limiting oblique hole 7, thereby increasing the friction between the limiting oblique hole 7 and the constraint tube 3, and ensuring the installation stability of the constraint tube 3.

[0015] The specific working principle is as follows: each test tube can be placed inside the corresponding constraint tube 3. The constraint tube 3 forms a wrap-around protection and positioning function for the test tube. At the same time, when the test tube is placed inside the constraint tube 3, each abutting ball 6 abuts against the outside of the test tube. After the elastic ring 5 is deformed by force, it resets and clamps the outside of the test tube, ensuring the stability of the test tube placed inside the constraint tube 3. It can also adapt to test tubes of different sizes. The setting of the limiting oblique hole 7 makes it convenient to install the constraint tube 3 on the support plate 1 for positioning the constraint tube 3, and also makes it convenient to pull the constraint tube 3 out of the support plate 1, making it easy to put and take off the constraint tube 3.

[0016] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
