Description
Technical Field
[0001] The utility model relates to the technical field of centrifuge tube racks, in particular to an integrated multi-purpose centrifuge tube rack. Background Art
[0002] Currently, the commonly used centrifuge tubes in laboratories mainly have specifications of 250 mL, 50 mL, 15 mL, 10 mL, 5 mL, 2 mL, and 1.5 mL. In order to ensure that the samples for centrifugation experiments can gather together (the conventional requirement of centrifugation experiments), the bottom of the centrifuge tube is usually conical or circular in structure, with the conical bottom being more common, which is not convenient to directly place on a support plane. Therefore, in laboratories, centrifuge tubes are generally placed on centrifuge tube racks. And during biological or medical experiments, centrifuge tubes of different specifications are often exchanged and used. Therefore, centrifuge tube racks of different specifications need to be matched to meet the experimental requirements and ensure the safe and orderly placement of samples.
[0003] Currently, most centrifuge tube racks have a single aperture size and only fix one centrifuge tube specification. During experiments such as cell culture, centrifuge tubes of various different specifications and lengths are often used. Therefore, multiple centrifuge tube racks need to be prepared. However, the space on the experimental bench is limited. When placing multiple centrifuge tube racks, it will occupy a large amount of space, resulting in limited space and a messy tabletop, which is not convenient for experimental operations and affects work efficiency. Moreover, on the top plate of the current centrifuge tube racks, there are generally jacks for placing centrifuge tubes, and on the bottom plate of the tube rack, there are hole grooves for supporting the bottom of the centrifuge tube. However, it has certain limitations during use. It is only applicable to centrifuge tubes with a single size specification and cannot adjust its fixing position according to centrifuge tubes of different specifications and lengths, failing to effectively ensure the stability of the centrifuge tube placed on the centrifuge tube rack. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide an integrated multi-purpose centrifuge tube rack, which can place centrifuge tubes of various specifications by flipping, saves the space of the experimental bench, and can adjust and fix the bottom according to centrifuge tubes of different specifications and lengths, solving the problem of poor stability of the centrifuge tube placed on the centrifuge tube rack.
[0005] To achieve the above object, the utility model provides the following technical solution: an integrated multi-purpose centrifuge tube rack, which is characterized in that it includes a first placement plate, a limiting plate and a second placement plate arranged in sequence from top to bottom. The four corners of the first placement plate and the second placement plate are respectively connected by support rods. The limiting plate is slidably arranged on the support rods. Sliding limit members are provided at the left and right ends of the limiting plate to limit the sliding height of the limiting plate. A plurality of first placement holes are provided on the first placement plate, a plurality of second placement holes are provided on the second placement plate, and a plurality of first limiting holes corresponding to the first placement holes and a plurality of second limiting holes corresponding to the second placement holes are respectively provided on the limiting plate, so as to satisfy that when the conical centrifuge tube is placed into the first placement hole or the second placement hole, the first limiting hole or the second limiting hole plays a role in supporting the conical bottom of the conical centrifuge tube.
[0006] Further, the sliding limit member includes a threaded adjusting rod, and double nuts that are threadedly engaged with the threaded adjusting rod are provided on the threaded adjusting rod. One of the double nuts is located above the limiting plate, and the other is located below the limiting plate. The upper and lower limiting heights of the limiting plate are adjusted by adjusting the double nuts, and the limiting plate is locked.
[0007] Further, the plurality of first placement holes can be set to have the same or different hole diameters according to needs, and the plurality of second placement holes can be set to have the same or different hole diameters according to needs; correspondingly, the first limiting holes are matched with the first placement holes to set the hole diameter size, and the second limiting holes are matched with the second placement holes to set the hole diameter size.
[0008] Further, the hole diameter of the first placement hole is larger than the hole diameter of the first limiting hole; the hole diameter of the second placement hole is larger than the hole diameter of the second limiting hole.
[0009] Further, support seats are provided at the top end of the first placement plate and the bottom end of the second placement plate, so as to ensure that there are support seats for support when the first placement plate or the second placement plate is placed in a flipped manner.
[0010] Further, there are 4 first placement holes with a hole diameter of 64 mm, which are adapted to place 250 ml centrifuge tubes; there are 16 second placement holes with a hole diameter of 30 mm, which are adapted to place 50 ml centrifuge tubes; there are 4 first limiting holes with a hole diameter of 20 mm; and there are 16 second limiting holes with a hole diameter of 15 mm.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0016] As Figure 1 shown, an integrated multi-purpose centrifuge tube rack includes a first placement plate 1, a limiting plate 2, and a second placement plate 3 arranged in sequence from top to bottom. Support bases 7 are provided at the top end of the first placement plate 1 and the bottom end of the second placement plate 3, so as to ensure that there is a support base 7 for support when the first placement plate 1 or the second placement plate 3 is placed in a flipped manner; the four corners of the first placement plate 1 and the second placement plate 3 are respectively connected by support rods 4, the limiting plate 2 is slidably arranged on the support rods 4, and sliding limiting members are provided at the left and right ends of the limiting plate 2 to limit the sliding height of the limiting plate 2. The sliding limiting members include a thread adjusting rod 5, and double nuts 6 that are in threaded cooperation with the thread adjusting rod are provided on the thread adjusting rod 5. One of the double nuts 6 is located above the limiting plate 2, and the other is located below the limiting plate 2. By adjusting the double nuts 6, the upper and lower limiting heights of the limiting plate 2 are adjusted and the limiting plate 2 is locked; 4 first placement holes 11 with a hole diameter of 64 mm are provided on the first placement plate 1, which are adapted to place 250 ml centrifuge tubes; 16 second placement holes are provided on the second placement plate 3 with a hole diameter of 30 mm, which are adapted to place 50 ml centrifuge tubes; 4 first limiting holes 21 corresponding to the first placement holes 11 with a hole diameter of 20 mm and 16 second limiting holes 22 corresponding to the second placement holes 22 with a hole diameter of 15 mm are respectively provided on the limiting plate 2, so as to meet the requirement that when a conical centrifuge tube is placed into the first placement hole 11 or the second placement hole 31, the first limiting hole 21 or the second limiting hole 22 plays a role in supporting the conical bottom of the conical centrifuge tube.
[0017] Furthermore, the first placement hole 11 can be set to several placement holes with different aperture diameters as required, and the second placement hole can be set to several aperture diameters with different sizes as required; correspondingly, the first limiting hole 21 is set to match the aperture size of the first placement hole 11, and the second limiting hole 22 is set to match the aperture size of the second placement hole 31.
[0018] The working principle and usage process of the present utility model: During use, adjust the double nuts 6 according to the length of the 250 ml conical centrifuge tube, thereby limiting and locking the limiting plate 2 (at this time, the height of the limiting plate 2 satisfies that the first limiting hole 21 supports the conical bottom of the 250 ml conical centrifuge tube placed therein). Subsequently, place the 250 ml conical centrifuge tube on the first placement hole 11. At this time, the 250 ml conical centrifuge tube is stably placed on the limiting plate 2; when it is necessary to exchange and use conical centrifuge tubes of different specifications, flip the present utility model so that the originally lower-layer second placement plate becomes the upper layer, which can be used to place a 50 ml conical centrifuge tube. Adjust the double nuts 6 according to the height of the 50 ml conical centrifuge tube, thereby limiting and locking the limiting plate 2, so that the second limiting hole 22 on the limiting plate 2 supports the conical bottom of the 50 ml conical centrifuge tube, stabilizing the 50 ml conical centrifuge tube. Thus, by flipping, centrifuge tubes of various required specifications can be placed, achieving the purpose of reasonably utilizing space and multi-functional use of one device.
