Description

Technical Field

[0001] The utility model relates to the technical field of plate racks, and particularly relates to a plate rack structure adapted to large-diameter cryogenic tubes. Background Art

[0002] Cryogenic tubes are common experimental consumables in laboratories and are used to store biological samples. A cryogenic tube includes a tube body and a lid threadedly connected to the mouth of the tube body. The cryogenic tube needs to be used in conjunction with a cryogenic box, which includes a plate rack and a box lid covering the plate rack.

[0003] See Figure 1 , the current plate rack includes a plate rack body 1, and a plurality of square jacks 2 distributed in a matrix are provided on the plate rack body 1. When inserting a cryogenic tube into the square jack 2, the outer wall of the cryogenic tube fits against the four hole walls of the square jack 2.

[0004] As can be seen from the above introduction, the diameter of the cryogenic tube is the side length of the square jack. However, for large-diameter cryogenic tubes with an aperture larger than the side length of the square jack, the above square jack cannot accommodate them.

[0005] The length and width specifications of the plate rack are usually fixed because a capping device can only be adapted to a plate rack of one specification, and the capping device is used to screw open the lid in the cryogenic tube.

[0006] Therefore, while not changing the length and width specifications of the plate rack, enabling the plate rack to be adapted to large-diameter cryogenic tubes is a technical problem that needs to be solved currently. Summary of the Utility Model

[0007] Aiming at the above-mentioned deficiencies existing in the prior art, the utility model provides a plate rack structure adapted to large-diameter cryogenic tubes, which can enable the plate rack to be adapted to large-diameter cryogenic tubes without changing the length and width specifications of the plate rack.

[0008] To achieve the above object, the technical solution adopted by the utility model is:

[0009] A plate rack structure adapted to large-diameter cryogenic tubes includes a plate rack body. A plurality of square jacks distributed in a matrix are provided on the plate rack body. Among them, the plate rack body is a rectangular frame structure, and a bottom plate is provided at the bottom of the plate rack body. A plurality of support columns are provided on the top surface of the bottom plate. Plug plates are detachably connected to the side walls of the support columns and the side walls of the plate rack body. Four plug plates, two plug plates and two adjacent side walls of the plate rack body, and three plug plates and one side wall of the plate rack body all enclose to form the square jacks. Arc-shaped grooves are provided on the four hole walls of the square jacks, and the arc-shaped grooves are used to fit against the outer wall of the cryogenic tube.

[0010] Further, slots are provided on the side walls of the plate rack body and the side walls of the support columns, and the plug plates are in plug-in fit with the slots.

[0011] Furthermore, the support columns are cylindrical.

[0012] Furthermore, a rotation prevention portion is provided at the bottom of the arc-shaped groove, and the rotation prevention portion is used to abut against the limiting portion at the bottom of the cryogenic tube.

[0013] Furthermore, a plurality of windows distributed in a matrix are provided on the bottom plate, and each square jack is communicated with a window, and the window is used to expose the identification code at the bottom of the cryogenic tube.

[0014] Furthermore, the window is a square hole.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, since arc-shaped grooves are provided on the four hole walls of the square jack, when inserting the cryogenic tube into the square jack, the arc-shaped grooves can fit the outer wall of the cryogenic tube. Therefore, compared with the background art, the present utility model can insert and place cryogenic tubes with a larger diameter. Moreover, the present utility model does not need to change the length and width specifications of the plate rack body. Thus, the present utility model can make the plate rack body adapt to large-diameter cryogenic tubes without changing the length and width specifications of the plate rack body.

[0017] 2. Since the insertion plate is inserted and matched with the slot, when the insertion plate is damaged, the damaged insertion plate can be pulled out from the slot, and then a new insertion plate can be replaced. The maintenance is convenient, which can not only improve the maintenance efficiency, but also realize partial replacement without overall replacement, saving costs.

[0018] 3. Since the support columns are cylindrical, there are no edges and corners on the side surfaces of the support columns, which can prevent the edges and corners from scratching the cryogenic tube inserted into the square jack and improve the use safety of the cryogenic tube.

[0019] 4. By providing a rotation prevention portion at the bottom of the arc-shaped groove, the rotation prevention portion can be used to abut against the limiting portion at the bottom of the cryogenic tube. After the rotation prevention portion abuts against the limiting portion, when screwing the cover of the cryogenic tube, the tube body of the cryogenic tube can be kept from rotating, ensuring the reliability of screwing and opening the cover of the cryogenic tube.

[0020] 5. By providing a window on the bottom plate, the identification code at the bottom of the cryogenic tube can be exposed through the window, which is convenient for the scanning device to identify and improves the use flexibility of the present utility model. Description of the Drawings

[0040] Embodiment:

[0041] Refer to Figure 2 、 Figure 4 、 Figure 6, Figure 7 , a plate rack structure adapted to a large-diameter cryotube, comprising a plate rack body 1, and the plate rack body 1 is a rectangular frame structure.

[0042] See Figure 4 , Figure 5 and Figure 7 , a bottom plate 3 is provided at the bottom of the plate rack body 1, and the bottom plate 3 and the plate rack body 1 are of an integral structure. A plurality of windows 4 distributed in a matrix are provided on the bottom plate 3, and the windows 4 are square holes.

[0043] See Figure 3 , a plurality of support columns 5 are fixedly installed on the top surface of the bottom plate 3, and the support columns 5 are cylinders.

[0044] See Figure 3 , slots 6 are provided on the side walls of the plate rack body 1 and the side walls of the support columns 5, and inserting plates 7 are inserted into the slots 6.

[0045] See Figure 2 and Figure 3 , at the corners of the plate rack body 1, two inserting plates 7 and two adjacent side walls of the plate rack body 1 surround to form a square jack 2. At the side of the plate rack body 1, three inserting plates 7 and one side wall of the plate rack body 1 surround to form a square jack 2. In the middle of the plate rack body 1, four inserting plates 7 surround to form a square jack 2. All the square jacks 2 are distributed in a matrix.

[0046] See Figure 5 , each square jack 2 is communicated with a window 4, and the window 4 is used to expose the identification code at the bottom of the cryotube, which is convenient for the existing code scanning device to scan and identify, and improves the use flexibility.

[0047] See Figure 3 , arc-shaped grooves 8 are provided on the four pore walls of the square jack 2, and the arc-shaped grooves 8 are used to fit the outer wall of the cryotube.

[0048] See Figure 5 and Figure 6 , a rotation stopping portion 9 is fixedly installed at the bottom of the arc-shaped groove 8, and the rotation stopping portion 9 is used to abut against the limiting portion at the bottom of the cryotube. After the rotation stopping portion 9 abuts against the limiting portion, when the cover of the cryotube is screwed, the tube body of the cryotube can be kept from rotating, ensuring the reliability of screwing and opening the cover of the cryotube.

[0049] In this embodiment, because arc-shaped grooves 8 are provided on the four pore walls of the square jack 2, when inserting the cryotube into the square jack 2, the arc-shaped grooves 8 can fit the outer wall of the cryotube. Therefore, compared with the background art, this embodiment can insert and place cryotubes with a larger diameter. And, this embodiment does not need to change the length and width specifications of the plate rack body 1. Thus, this embodiment can make the plate rack body 1 adapt to large-diameter cryotubes without changing the length and width specifications of the plate rack body 1.

[0050] See Figure 8 , the diameter of the cryopreservation tube adapted to the square socket 2 provided with the arc-shaped groove 8 is D1, and the diameter of the cryopreservation tube adapted to the square socket 2 without the arc-shaped groove 8 is D2, and D1 is greater than D2.

[0051] Since the insertion plate 7 is inserted and matched with the slot 6, when the insertion plate 7 is damaged, the damaged insertion plate 7 can be pulled out from the slot 6, and then a new insertion plate 7 can be replaced. The maintenance is convenient, which can not only improve the maintenance efficiency, but also achieve partial replacement without overall replacement, saving costs.

[0052] Since the support column 5 is a cylinder, there are no edges and corners on the side of the support column 5, which can prevent the edges and corners from scratching the cryopreservation tube inserted into the square socket 2 and improve the use safety of the cryopreservation tube.

[0053] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
