[0019] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0020] It should be noted that when a component is referred to as "fixed to" another component, it can be directly on the other component or there may also be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] As shown in the attached Figure 1 The combined centrifuge tube rack of the present utility model is shown, which includes a plurality of racks 1 for supporting centrifuge tubes of different specifications. As shown in the attached Figure 2 As shown, the rack 1 includes a top surface 2, a bottom surface, and four side surfaces connecting the top surface 2 and the bottom surface. The top surface 2 of the rack 1 has tube holes 21 for placing centrifuge tubes. The side surfaces of the rack 1 include two groups of opposite first side surfaces 3 and second side surfaces 4. At least one horizontal groove 31 is machined on one of the two first side surfaces 3, and a rib 32 corresponding to the groove 31 is formed on the other. The corresponding distances between the groove 31 and the bottom surface on different racks 1 are the same, so that the bottom surfaces are on the same horizontal plane when two or more racks 1 are spliced. The width of the bottom of the groove 31 is greater than the width of the groove opening, and the rib 32 can be inserted into the grooves 31 on different racks along the length direction to prevent it from coming out. A long hole 41 is provided at a position near the bottom surface on the second side surface 4, and a detachable insertion rod 5 is placed in the long hole 41. A through hole 33 corresponding to the shape of the insertion rod 5 is formed at a position near the bottom surface on the first side surface 3. The insertion rod 5 is used to insert into the through hole 33 to connect at least two racks 1 in series, and after the groove 31 and the rib 32 have restricted the movement of the rack 1 in one direction, the degree of freedom in the vertical direction of this direction is restricted again to prevent the relative positions of the racks 1 from changing randomly. The combined connection method of the groove 31, the rib 32, the insertion rod 5, and the through hole 33 makes the connection between the racks 1 more stable and prevents relative shaking. When multiple racks 1 do not need to be connected, the insertion rod 5 can be placed back into the long hole 41 to prevent the insertion rod 5 from being scattered and lost.

[0022] The long hole 41 and the through hole 33 can be at different heights or at the same height. To avoid interfering with the bottom of the tube hole 21, the bottom needs to be located above the long hole 41 and the through hole 33. In this embodiment, the distances between the long hole 41 and the through hole 33 and the bottom surface are the same, which makes the volume occupied by the rack 1 in the height aspect smaller under the condition that the depth of the tube hole 21 remains unchanged, saving space.

[0023] The cross-section of the insertion rod 5 can be circular, rectangular or other suitable shapes. In this embodiment, the cross-section of the insertion rod 5 is square, which can prevent relative rotation between different frame bodies 1 after being inserted into the through hole 33, further enhancing the connection stability.

[0024] As shown in the Figure 3 accompanying drawings, the groove 31 includes a groove body 311 communicating with the first side surface 3. At a position of the groove body 311 far from the first side surface 3, depressions 312 extending to both sides are formed. On the rib 32, ribs 321 corresponding to the depressions 312 are formed, which not only strengthens the guiding effect when the rib 32 enters the groove 31, making the movement more stable and smooth, but also prevents the rib 32 from easily disengaging from the groove 31, making the connection more stable.

[0025] The frame body 1 has various volumes and shapes and is suitable for various centrifugal tubes of different specifications. As shown in the Figure 4 accompanying drawings, in this embodiment, the frame body 1 includes a first frame body 11, a second frame body 12 and a third frame body 13. The capacities of the centrifugal tubes placed on the first frame body 11, the second frame body 12 and the third frame body 13 decrease in sequence. Two grooves 31 are provided on the first frame body 11 and the second frame body 12, and one groove 31 is provided on the third frame body 13. After the three frame bodies 1 are connected through the grooves 31 and the ribs 32 on the first side surface 3, the insertion rod 5 is inserted into the through hole 33 from the through hole 41 in series, and different frame bodies 1 are freely combined together. The length of the first side surface 3 is greater than the length of the second side surface 4, making the shape of the combined multiple frame bodies 1 more reasonable. In other embodiments, there can be more types of combined connections of the frame body 1 to meet the placement requirements of more centrifugal tubes of different specifications.

[0026] The combined centrifugal tube rack of the present utility model has a simple structure and is convenient to use. When it is necessary to hold and use centrifugal tubes of multiple different specifications, only need to insert the rib 32 into the groove 31 along the first side surface 3 of the required frame body 1, and then pull out the insertion rod 5 in the long hole 41 and insert it into the through hole 33, then multiple frame bodies 1 can be tightly combined together, reducing the space occupation and making it convenient to take and use the centrifugal tubes.

[0027] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification of the present utility model, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present utility model.
