Description

Technical Field

[0001] The utility model relates to the technical field of biological sample storage equipment, and particularly relates to a plate rack with adjustable plate hole sizes. Background Art

[0002] When collecting biological samples in batches, it is necessary to load the biological samples into individual cryotubes and then insert the cryotubes into the individual plate holes of the plate rack. Since the sizes of the plate holes on the plate rack are fixed, it is necessary to select a plate rack with corresponding plate hole specifications to match the specifications of the cryotubes. In actual use, due to the large number of plate racks, it is inconvenient to allocate.

[0003] In this regard, in the patent with the publication number CN219668803U, "Cryogenic Storage Box with Multiple Specifications Adaptability" is disclosed. The patent includes a cryogenic storage box body and a dust-proof cover body. Inside the cryogenic storage box body, there is a combined grid rack, which is formed by horizontally and vertically intersecting and plugging a number of grid unit plates. The grid unit plates are provided with a number of multi-specification slots along the length direction. By plugging, the positions of the horizontal grid unit plates and the vertical grid unit plates can be adjusted, and thus the size of the grid can be adjusted.

[0004] Although the above patent can adjust the size of the grid (i.e., the plate hole), due to the large number of grid unit plates, the adjustment efficiency is reduced.

[0005] Therefore, how to improve the efficiency of adjusting the size of the plate hole is a technical problem that needs to be solved currently. Content of the Utility Model

[0006] Aiming at the above-mentioned deficiencies of the existing technology, the utility model provides a plate rack with adjustable plate hole sizes, which can improve the efficiency of adjusting the size of the plate hole.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A plate rack with adjustable plate hole sizes includes a cryogenic storage box body and a dust-proof cover body. A first plate body is provided on the top of the cryogenic storage box body, and a second plate body is provided on the bottom of the cryogenic storage box body. The first plate body is provided with first plate holes distributed in a matrix, and the second plate body is provided with second plate holes distributed in a matrix. A second plate hole is correspondingly arranged at the middle position of every four matrix-distributed first plate holes. The aperture of the first plate hole is larger than that of the second plate hole. The dust-proof cover body is buckled on the top or the bottom of the cryogenic storage box body.

[0009] Furthermore, a first cylinder body is provided on the bottom surface of the first plate body, and the first cylinder body is communicated with the first plate hole; a second cylinder body is provided on the top surface of the second plate body, and the second cylinder body is communicated with the second plate hole.

[0010] Furthermore, a first anti-rotation component is provided on the top surface of the second plate body, and the first anti-rotation component includes a plurality of first protrusions distributed along the circumference of the first plate hole; a second anti-rotation component is provided on the bottom surface of the first plate body, and the second anti-rotation component includes a plurality of second protrusions distributed along the circumference of the second plate hole.

[0011] Furthermore, the first plate body and the second plate body are both transparent plates.

[0012] Furthermore, a first step is provided on the upper portion of the inner wall of the freezing box body, a second step is provided on the lower portion of the inner wall of the freezing box body, slots are provided on the upper portion and the lower portion of the inner wall of the freezing box body, a wedge block is slidably connected in the slot, the wedge block is connected to the slot wall through an elastic member, the elastic member is used to push the wedge block horizontally outward, a pushing portion is provided on the wedge block, the first plate body is provided between the first step and the wedge block on the upper portion of the inner wall of the freezing box body, and the second plate body is provided between the second step and the wedge block on the lower portion of the inner wall of the freezing box body.

[0013] Furthermore, a first latch hole is provided on the top of the freezing box body, a second latch hole is provided on the bottom of the freezing box body, a mounting groove is provided on the side of the dustproof cover body, a prying portion is provided in the mounting groove, a clamping block is provided on the inner side of the prying portion, and the clamping block cooperates with the first latch hole or the second latch hole.

[0014] The utility model has the beneficial effects:

[0015] 1. Compared with the background technology, the present invention only needs to flip the cryopreservation box body when adjusting the plate hole size. When the first plate body is facing upward, the first plate hole with a larger hole diameter on the first plate body can be used to accommodate the cryopreservation tube; when the second plate body is facing upward, the second plate hole with a smaller hole diameter on the second plate body can be used to accommodate the cryopreservation tube. The operation is simple and quick, which can improve the efficiency of adjusting the plate hole size.

[0016] 2. The first protrusion in the first anti-rotation component and the second protrusion in the second anti-rotation component can both be used to abut against the anti-rotation portion at the bottom of the cryogenic tube. Therefore, when the tube cover at the top of the cryogenic tube is screwed open, the first protrusion and the second protrusion can prevent the tube body of the cryogenic tube from rotating together, which is beneficial to ensuring the reliability of opening the cryogenic tube.

[0017] 3. Because both the first plate and the second plate are transparent plates, the first plate and the second plate will not block the identification code at the bottom of the cryopreservation tube, making it convenient for the identification instrument to scan and identify the code.

[0018] 4. By setting the first step, the second step, the slot, the wedge block, and the elastic member, the first plate body and the second plate body can be disassembled and assembled in the freezing box body, which facilitates the replacement of the first plate body and the second plate body and the plate body with other sizes of plate holes, thereby improving the flexibility of use.

[0019] 5. The disassembly and assembly of the first plate body and the second plate body is simple and quick, which is conducive to improving the disassembly and assembly efficiency. When replacing a plate body with plate holes of other sizes, the replacement and adjustment efficiency can be improved.

[0020] 6. By providing the first clamping hole, the second clamping hole, the prying part and the clamping block, the dust cover can be conveniently fastened to the top or bottom of the freezing box body, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] In order to better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings. It is worth noting that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0044] Embodiment 1:

[0045] See also Figure 1 , Figure 2 , Figure 7 , Figure 11 A plate rack with adjustable plate hole size comprises a freezing box body 1 and a dust cover body 2. A first plate body 3 is installed on the top of the freezing box body 1, and a second plate body 4 is installed on the bottom of the freezing box body 1. The first plate body 3 is provided with first plate holes 31 distributed in a matrix, and the second plate body 4 is provided with second plate holes 41 distributed in a matrix, and a second plate hole 41 is correspondingly arranged in the middle position of every four first plate holes 31 distributed in the matrix. The aperture of the first plate hole 31 is larger than the aperture of the second plate hole 41. The dust cover body 2 is buckled on the top of the freezing box body 1 or the bottom of the freezing box body 1.

[0046] The working principle of Embodiment 1 is as follows:

[0047] The first plate body 3 and the second plate body 4 on the cryopreservation box body 1 can provide two sizes of plate holes for users to choose from. When a larger plate hole is needed, the cryopreservation tube 5 can be directly inserted into the first plate hole 31 of the first plate body 3; when a smaller plate hole is needed, the cryopreservation box body 1 is flipped so that the second plate body 4 faces upward, and the cryopreservation tube 5 is inserted into the second plate hole 41 of the second plate body 4. When using the first plate hole 31 of the first plate body 3, the dust-proof cover body 2 is buckled on the top of the cryopreservation box body 1; when using the second plate hole 41 of the second plate body 4, the dust-proof cover body 2 is buckled on the bottom of the cryopreservation box body 1.

[0048] Compared with the background technology, in Embodiment 1, when adjusting the size of the plate hole, only the cryopreservation box body 1 needs to be flipped. When the first plate body 3 faces upward, the first plate hole 31 with a larger aperture on the first plate body 3 can be used to accommodate the cryopreservation tube 5; when the second plate body 4 faces upward, the second plate hole 41 with a smaller aperture on the second plate body 4 can be used to accommodate the cryopreservation tube 5. The operation is simple and rapid, and the efficiency of adjusting the size of the plate hole can be improved.

[0049] Embodiment 2:

[0050] On the basis of Embodiment 1, Embodiment 2 is further improved:

[0051] See Figure 12 and Figure 13 , a first cylinder body 32 is provided on the bottom surface of the first plate body 3. The first cylinder body 32 and the first plate body 3 are of an integral structure, and the first cylinder body 32 communicates with the first plate hole 31. See Figure 14 and Figure 15 , a second cylinder body 42 is provided on the top surface of the second plate body 4. The second cylinder body 42 and the second plate body 4 are of an integral structure, and the second cylinder body 42 communicates with the second plate hole 41. The settings of the first cylinder body 32 and the second cylinder body 42 can improve the stability of inserting the cryopreservation tube 5 into the first plate hole 31 and the second plate hole 41.

[0052] See Figure 14 , a first anti-rotation component is provided on the top surface of the second plate body 4. The first anti-rotation component includes a plurality of first convex parts 43 distributed along the circumferential direction of the first plate hole 31. The first convex parts 43 and the second plate body 4 are of an integral structure, and the first anti-rotation component is used in cooperation with the first plate hole 31. See Figure 12 , a second anti-rotation component is provided on the bottom surface of the first plate body 3. The second anti-rotation component includes a plurality of second convex parts 33 distributed along the circumferential direction of the second plate hole 41. The second convex parts 33 and the first plate body 3 are of an integral structure, and the second anti-rotation component is used in cooperation with the second plate hole 41.

[0053] Both the first plate body 3 and the second plate body 4 are made of transparent plates.

[0054] SeeFigure 16 At the bottom of the cryotube 5, a plurality of anti-rotation parts 51 distributed in a circle are installed, and an identification code 52 is installed on the cryotube 5.

[0055] The working principle of Embodiment 2 is as follows:

[0056] When the cryotube 5 is inserted into the first plate hole 31 until the bottom of the cryotube 5 lands on the second plate body 4, the anti-rotation part 51 at the bottom of the cryotube 5 can abut against the first convex part 43 in the first anti-rotation assembly. When screwing to open the tube cap at the top of the cryotube 5, the first convex part 43 can prevent the body of the cryotube 5 from rotating together, ensuring the reliability of opening the cryotube 5.

[0057] When the cryotube 5 is inserted into the second plate hole 41 until the bottom of the cryotube 5 lands on the first plate body 3, the anti-rotation part 51 at the bottom of the cryotube 5 can abut against the second convex part 33 in the second anti-rotation assembly. When screwing to open the tube cap at the top of the cryotube 5, the second convex part 33 can prevent the body of the cryotube 5 from rotating together, ensuring the reliability of opening the cryotube 5.

[0058] Since both the first plate body 3 and the second plate body 4 are made of transparent plates, the first plate body 3 and the second plate body 4 do not block the identification code 52 at the bottom of the cryotube 5, facilitating the identification instrument to scan and identify.

[0059] Embodiment 3:

[0060] On the basis of Embodiment 1 or Embodiment 2, this Embodiment 3 is further improved:

[0061] See Figure 9 On the upper part of the inner wall of the cryobox body 1, a first step 11 is provided, and on the lower part of the inner wall of the cryobox body 1, a second step 12 is provided.

[0062] See Figure 6 、 Figure 8 、 Figure 10 On both the upper part and the lower part of the inner wall of the cryobox body 1, a slot 13 is provided. A wedge-shaped block 14 is slidably connected in the slot 13. The wedge-shaped block 14 is connected to the slot wall of the slot 13 through an elastic member. The elastic member can adopt a spring 15, and the elastic member is used to horizontally push out the wedge-shaped block 14. A pushing part 16 is provided on the wedge-shaped block 14, and the pushing part 16 and the wedge-shaped block 14 are of an integral structure.

[0063] See Figure 10 The first plate body 3 is arranged between the first step 11 and the wedge-shaped block 14 on the upper part of the inner wall of the cryobox body 1. See Figure 9 The second plate body 4 is arranged between the second step 12 and the wedge-shaped block 14 on the lower part of the inner wall of the cryobox body 1.

[0064] The working principle of Embodiment 3 is as follows:

[0065] When the first plate 3 needs to be removed: (1) the user overcomes the elastic force of the elastic member and pushes the push portion 16 on the wedge block 14 to both sides, so that the wedge block 14 leaves the top surface of the first plate 3. (2) the user keeps pushing the wedge block 14 and flips the freezing box 1, so that the first plate 3 falls down, and the first plate 3 can be removed; or other personnel hook the first plate hole 31 and take out the first plate 3, so that the first plate 3 can be removed. The principle of removing the second plate 4 is the same as above.

[0066] When the first plate body 3 needs to be installed, the user hooks the first plate hole 31 and directly puts the first plate body 3 downward into the freezing box body 1. During the lowering process, the first plate body 3 pushes the inclined surface of the wedge block 14, so that the wedge block 14 overcomes the elastic force of the elastic member and retreats into the slot 13. When the first plate body 3 falls on the first step 11, the top surface of the first plate body 3 is lower than the bottom surface of the wedge block 14. The wedge block 14 can extend out of the slot 13 under the elastic force of the elastic member, so that the first plate body 3 is sandwiched between the first step 11 and the wedge block 14, and the installation of the first plate body 3 is completed. The installation principle of the second plate body 4 is the same as above.

[0067] It can be seen from the above working principle that the present embodiment 3 can realize the disassembly and assembly of the first plate body 3 and the second plate body 4 in the freezing box body 1, and facilitates the replacement of the first plate body 3 and the second plate body 4 as well as the plate bodies with other sizes of plate holes, thereby improving the flexibility of use.

[0068] Furthermore, the disassembly and assembly of the first plate body 3 and the second plate body 4 is simple and quick, which is conducive to improving the disassembly and assembly efficiency. When replacing a plate body with plate holes of other sizes, the replacement and adjustment efficiency can be improved.

[0069] Embodiment 4:

[0070] This embodiment 4 is further improved on the basis of embodiment 1, embodiment 2 or embodiment 3:

[0071] See also Figure 5 , Figure 9 A first latch hole 17 is provided at the top of the freezing box body 1, and a second latch hole 18 is provided at the bottom of the freezing box body 1.

[0072] See also Figure 3 and Figure 4 The side of the dust cover 2 is provided with a mounting groove 21. A bendable portion 22 is provided in the mounting groove 21. The top of the bendable portion 22 is an integral structure with the freezing box body 1. There is a gap between the two sides of the bendable portion 22 and the groove wall of the mounting groove 21. The bottom surface of the bendable portion 22 is higher than the bottom surface of the side of the dust cover 2, so that the user can use his fingers or nails to grab the bottom of the bendable portion 22 and bend it outward. A clamping block 23 is provided on the inner side of the bendable portion 22. The clamping block 23 is an integral structure with the bendable portion 22. The clamping block 23 is used to cooperate with the first clamping hole 17 or the second clamping hole 18.

[0073] The working principle of this embodiment 4 is as follows:

[0074] When the dust cover 2 is buckled onto the top of the freezing box 1: the user first bends the bend portion 22 outward, then buckles the dust cover 2 onto the top of the freezing box 1, and then releases the bend portion 22, the bend portion 22 is reset, and the block 23 located inside the bend portion 22 is inserted into the first clamping hole 17 at the top of the freezing box 1, so that the dust cover 2 is buckled. The operation of buckling the dust cover 2 onto the bottom of the freezing box 1 is the same as above, and the block 23 inside the bend portion 22 is inserted into the second clamping hole 18.

[0075] When opening the dust cover 2 at the top of the freezing box 1, the user moves the prying part 22 outwards, so that the block 23 inside the prying part 22 is withdrawn from the first clamping hole 17, and then the dust cover 2 is taken away. The operation of opening the dust cover 2 at the bottom of the freezing box 1 is the same as above, and the block 23 is withdrawn from the second clamping hole 18, and then the dust cover 2 at the bottom of the freezing box 1 can be taken away.

[0076] It can be seen from the above working principle that the present embodiment 4 can conveniently buckle the dust cover body 2 to the top or bottom of the freezing box body 1 by providing the first clamping hole 17, the second clamping hole 18, the prying portion 22, and the clamping block 23, and the operation is simple.

[0077] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
