Description

Technical Field

[0001] This utility model relates to the field of biological sample storage equipment technology, and in particular to a cryopreservation basket. Background Technology

[0002] Cryopreservation baskets are crucial storage tools in the cryogenic storage of biological samples. Existing cryopreservation baskets typically employ a U-shaped design with an opening on one side for accessing the cryopreservation box. This structure is prone to inward or outward deformation after welding and during use when subjected to alternating low and normal temperatures, affecting the access and storage safety of the cryopreservation box. This problem is particularly prominent in large-capacity cryopreservation baskets.

[0003] Currently, cryopreservation baskets from different suppliers and batches on the market often have inconsistent spacing between their cryopreservation compartments, making them incompatible and requiring individual calibration for each basket, which increases usage costs and time. Furthermore, baskets without welded positioning are prone to stress due to contraction and expansion during temperature fluctuations, potentially leading to weld failure, tray collapse, and other safety hazards.

[0004] Furthermore, the traditional processing of cryopreservation baskets is typically complex, requiring specialized tooling and fixtures to ensure precision. This method not only increases production costs but also leads to inconsistent product quality in small-batch production due to varying processes among different suppliers. Additionally, any design changes necessitate corresponding modifications to the tooling and fixtures, resulting in resource waste and difficulty in ensuring consistency across different batches.

[0005] Therefore, there is an urgent need to develop a cryopreservation basket to solve the above problems. Utility Model Content

[0014] Furthermore, the end of the third plate away from the second inclined plate is bent toward the inside of the U-shaped frame to form a second positioning edge. The second positioning edge is used to strengthen the structural strength of the edge of the U-shaped frame and to position the cryopreservation box in the cryopreservation basket.

[0015] Furthermore, the strip-shaped support plate includes an integrally formed horizontal support portion and a vertical connecting portion, the vertical connecting portion being used to connect the U-shaped frame;

[0016] The first positioning edge is provided on both adjacent sides of the horizontal support portion, and the first positioning edge extends from the edge of the horizontal support portion and protrudes from the vertical connection portion.

[0017] Furthermore, it also includes a connecting plate; the connecting plate is mounted on the U-shaped frame; the U-shaped frame is provided with a plurality of spaced second positioning grooves, the second positioning grooves being distributed along the horizontal direction; the connecting plate is provided with a third positioning edge on the three sides that are fixed to the U-shaped frame, which respectively engage with the second positioning grooves.

[0019] Furthermore, it also includes three positioning posts; the side wall of the top seat is provided with positioning holes that are inserted and matched with the positioning posts; one end of the positioning post is located inside the positioning hole, and the other end extends outside the positioning hole.

[0020] Furthermore, the side wall of the base is provided with a bottom slope that is inclined toward the center of the lower surface of the base.

[0046] The following is a more detailed description of a cryopreservation basket according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0047] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0048] like Figures 1-5 As shown in the figure, this utility model embodiment proposes a convenient and practical cryopreservation basket, including a U-shaped frame 1, a multi-layer support frame, a top seat 3, and a base 4.

[0049] Specifically, the U-shaped frame 1 includes a back plate 12 and two oppositely arranged side plates 13, with the back plate 12 connected between the two side plates 13; the top seat 3 and the base 4 are respectively disposed at the upper and lower ends of the U-shaped frame 1 and are fixedly connected to the U-shaped frame 1; multiple layers of support frames are installed on the U-shaped frame 1 at intervals from top to bottom, and each layer of support frame includes two strip support plates 2, which are symmetrically arranged on the inner side wall of the U-shaped frame 1; the U-shaped frame 1 has multiple first positioning grooves 11 arranged in an array, and the side walls of the strip support plates 2 are provided with first positioning edges 21 that are inserted into and cooperate with the first positioning grooves 11.

[0050] Each layer of the support frame is used to support the cryopreservation box 8. The cryopreservation box 8 enters and exits through the access opening of the U-shaped frame 1 (i.e., the side opposite to the back panel 12).

[0051] This structure in this embodiment makes the connection between the strip support plate 2 and the U-shaped frame 1 more stable, thus improving the overall structural stability.

[0052] In this embodiment, any two adjacent support frames have the same predetermined spacing, which is the layer height and is set according to the height of the cryopreservation box 8. By distributing multiple layers of support frames at intervals, multiple placement spaces for the cryopreservation boxes 8 are formed, allowing the cryopreservation boxes 8 to be placed in layers, effectively improving space utilization.

[0053] In one embodiment, the U-shaped frame 1 is formed by integrally bending the back plate 12 and the two side plates 13, and the side plates 13 and / or the back plate 12 have a bending structure for strengthening the structural strength.

[0054] In one embodiment, the side plate 13 includes a first plate 131, a first inclined plate 132, a second plate 133, a second inclined plate 134, and a third plate 135 connected in sequence.

[0055] Specifically, the first inclined plate 132 is inclined inward toward the U-shaped frame 1 at the end away from the first plate 131, with an inclination angle of, for example, 30-60 degrees; the second plate 133 is arranged parallel to the first plate 131 and the third plate 135, and the first plate 131 and the third plate 135 are located in the same plane; the second inclined plate 134 is inclined outward toward the U-shaped frame 1 at the end away from the second plate 133, with an inclination angle of, for example, 30-60 degrees; the first positioning groove 11 is provided in the second plate 133. This bending structure design improves the strength of the side plate 13.

[0056] In this embodiment, the end of the third plate 135 away from the second inclined plate 134 is bent inward toward the U-shaped frame 1 to form a second positioning edge 136. The second positioning edge 136 is parallel to the third plate 135 and is used to strengthen the structural strength of the edge of the U-shaped frame 1 and to position the cryopreservation box 8 in the cryopreservation basket. This design enhances the structural strength of the third plate 135 while providing a positioning function.

[0057] In one specific embodiment, the strip-shaped support plate 2 includes an integrally formed horizontal support portion and a vertical connecting portion, the vertical connecting portion being used to connect the U-shaped frame 1; wherein, the first positioning edge 21 of the strip-shaped support plate 2 is inserted into the first positioning groove 11 of the U-shaped frame 1, and then fixed by spot welding after insertion. Figure 2 The horizontal support portion shown is provided with first positioning edges 21 on both adjacent sides. The first positioning edges 21 extend from the edge of the horizontal support portion and protrude from the vertical connecting portion. Each strip support plate 2 has two first positioning edges 21. Correspondingly, the back plate 12 and the two side plates 13 of the U-shaped frame 1 are provided with first positioning grooves 11 for inserting the first positioning edges 21.

[0058] Preferred, combined Figure 6 and Figure 7 As shown, this embodiment also includes a connecting plate 5. The connecting plate 5 is a rectangular plate with a hole in the center to reduce weight. The outer contour (three sides) of the connecting plate 5 abuts against the inner wall of the U-shaped frame 1, thereby strengthening the structural strength of the U-shaped frame 1 and preventing deformation.

[0059] Specifically, the connecting plate 5 is installed on the U-shaped frame 1; the U-shaped frame 1 is provided with a plurality of spaced second positioning grooves 14, that is, the back plate 12 and the two side plates 13 of the U-shaped frame 1 are all provided with second positioning grooves 14.

[0060] More specifically, the second positioning grooves 14 are distributed horizontally, and the spacing can be set according to actual needs; the connecting plate 5 has three sides (i.e., two third positioning edges 51 on each side) that are fixed to the U-shaped frame 1, respectively, which are provided with third positioning edges 51 that are inserted into the second positioning grooves 14. The third positioning edges 51 are inserted into the second positioning grooves 14 and then fixed by spot welding.

[0061] In this embodiment, the connecting plate 5 is made of the same metal sheet as the U-shaped frame 1, possessing good strength and toughness. The connecting plate 5 not only improves the overall stability of the U-shaped frame 1 but also enhances its torsional resistance. The horizontal direction is perpendicular to both the horizontal and vertical directions of the U-shaped frame 1.

[0062] In one embodiment, combined with Figure 6 and Figure 8 As shown, this embodiment also includes two symmetrically arranged hooks 6. Specifically, the top seat 3 is provided with a third positioning groove 31; the bottom end of the hook 6 is disposed in the third positioning groove 31 and fixedly connected to the top seat 3, and the top end of the hook 6 has a specified distance from the top seat 3, which can be set according to actual needs.

[0063] The hook 6 has a lifting hole 61 at its top end; the lifting hole 61 is perpendicular to the surface of the top seat 3. In this embodiment, the hook 6 is made of high-strength alloy material to ensure sufficient load-bearing capacity. The design of the hook 6 not only facilitates the handling of the basket but also allows for use with automated equipment.

[0064] For the best options, please continue to refer to them. Figure 1 and Figure 6 As shown, this embodiment also includes three positioning posts 7. Specifically, the side wall of the top seat 3 is provided with positioning holes 32 that engage with the positioning posts 7; one end of the positioning post 7 is located inside the positioning hole 32, and the other end extends outside the positioning hole 32. The positioning posts 7 are made of wear-resistant material and have been treated with rust prevention. When multiple baskets need to be stacked, the base 4 of the upper basket can engage with the positioning post 7 of the lower basket to improve stacking stability. The design of the positioning posts 7 not only enhances the positioning effect but also improves storage efficiency.

[0065] In this embodiment, reference continues to be made to Figures 8-10 As shown, a guide surface 611 is provided on the edge of the lifting hole 61. The guide surface 611 adopts a rounded transition design to avoid stress concentration. As those skilled in the art will know, the predetermined angle can be set according to actual needs. The design of the guide surface 611 improves the convenience of lifting operations and extends service life.

[0066] In one embodiment, such as Figures 11-12 As shown, the side wall of the base 4 has a bottom slope 41 that is inclined towards the center of the lower surface of the base 4. The bottom slope 41 is smooth to facilitate the sliding of the basket. The design of the bottom slope 41 not only improves the stability of the base 4, but also facilitates the positioning and placement of the basket.

[0067] In this embodiment, the side wall of the base 4 is also provided with a limiting edge 42 that cooperates with the bottom of the U-shaped frame 1. The limiting edge 42 is located above the bottom inclined surface 41. The limiting edge 42 and the bottom of the U-shaped frame 1 are engaged by a snap-fit ​​method, which is convenient for installation. The design of the limiting edge 42 improves the connection stability between the base 4 and the U-shaped frame 1 and prevents the base 4 from falling off.

[0068] In a specific example, the depth of the first positioning groove 11 is 3-5 mm and the width is 2-4 mm; the angle between the guide surface 611 of the lifting hole 61 and the vertical direction is 30-60 degrees; the angle between the bottom inclined surface 41 and the horizontal plane is 15-45 degrees; in the vertical direction, the predetermined distance between two adjacent support frames is 50-70 mm, which is applicable to most sizes of cryopreservation boxes 8. The U-shaped frame 1, strip support plate 2, top seat 3, and base 4 are all made of stainless steel and have good corrosion resistance after surface treatment. Those skilled in the art will understand that the above parameters can be adjusted according to actual needs, and other embodiments besides this one are also possible.

[0069] In this embodiment, such as Figure 13 As shown, when the cryopreservation box 8 needs to be stored, it is placed on the strip support plate 2, and stable support is achieved through the cooperation of the first positioning edge 21 and the first positioning groove 11. When it needs to be moved, it can be lifted through the lifting hole 61 on the hook 6. The bottom slope 41 and the limiting edge 42 make the basket placement more stable. The positioning post 7 facilitates the stacking and positioning of multiple baskets. When multiple baskets need to be stacked, the base 4 of the upper basket can be precisely aligned with the positioning post 7 of the lower basket to achieve reliable positioning.

[0070] In summary, the cryopreservation basket proposed in this utility model has the following advantages:

[0071] By setting a first positioning groove on the side wall of the U-shaped frame and cooperating with the first positioning edge of the strip support plate, a stable support structure is formed, which effectively solves the problem that the cryopreservation basket is prone to deformation during the alternation of low temperature and normal temperature in the prior art. At the same time, the spacing of the positioning groove ensures the consistency of the layer spacing, improving the versatility and interchangeability of the product.

[0072] In addition, the overall frame strength is further improved by adopting a special side plate structure design and connecting plate reinforcement structure, while simplifying the processing technology and reducing production costs. The design of the top seat and base not only facilitates the installation and retrieval of the basket, but also improves the ease of use through the design of the positioning column and bottom slope, and achieves stable lifting function through the design of the hook.

[0073] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
