[0037] Example embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings. While example embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0038] It is to be understood that the terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprises", "comprising", "includes", "including" and "has" are inclusive and therefore specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring their performance in the particular order in which they are described, unless specifically identified as an order dependent step. It is also to be understood that additional or alternative steps can be employed.

[0039] Although the terms first, second, third, and the like can be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms can be only used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second", and the like are used herein to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of example embodiments.

[0040] For the purposes of the description, a relative spatial term, such as "inner", "outer", "inwardly", "outwardly", "lower", "bottom", "top", "upper", and the like, can be used herein for describing an element's or feature's relationship to another element or feature as illustrated in the figures. Such relative spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" or "over" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0041] It is found through research that the existing storage devices for accommodating cryopreservation boxes are mostly multi-layer devices, each layer can accommodate one cryopreservation box, in some storage devices, all layers share one locking element to lock the cryopreservation boxes to prevent them from falling off, and in each time when the cryopreservation box is stored in the storage device or taken out from the storage device, the entire storage device needs to be taken out from the liquid nitrogen tank, the locking element is opened, and then the cryopreservation box of the target layer can be taken out, the entire process has problems of long operation time, inconvenience in taking the cryopreservation box, easy to take the wrong cryopreservation box, etc., thereby causing the cryopreservation rack to be exposed to the outside for a long time, the temperature is increased, and the quality of the cells is affected. In some other storage devices, each layer is provided with an independent locking element, and in each time when the cryopreservation box is stored in the storage device or taken out from the storage device, the locking and unlocking operations need to be performed, which consumes a long time, thereby causing the cryopreservation rack to be exposed to the outside for a long time, the temperature is increased, and the quality of the cells is affected. Therefore, the existing storage device has a problem of long time consumption in the process of storing and taking out the cryopreservation box, which seriously affects the quality of the cryopreservation of the cells or cell products. Based on the research on the above problems, the inventors propose a storage device and a freezing equipment to shorten the time length consumed in the process of storing and taking out the cryopreservation box, and improve the quality of the cryopreservation of the cells or cell products by the storage device.

[0042] As Figure 1As shown, according to the embodiments of the present application, a storage device 1 is provided, which comprises a frame and a plurality of storage assemblies 11, the plurality of storage assemblies 11 are arranged in a spaced manner along a first direction x, the storage assembly 11 comprises a partition plate 111 and a limiting stopper 112 arranged along at least part of the circumferential edge of the partition plate 111, the plane where the limiting stopper 112 is located intersects the plane where the partition plate 111 is located, the accommodating cavity 10 is formed between the adjacent two storage assemblies 11, and the distance between the adjacent two partition plates 111 is greater than the size of the limiting stopper 112 along the first direction x. The frame comprises a plurality of supports 21, which are arranged in a spaced manner along the circumferential edge of the partition plate 111 and are connected with the partition plate 111, and one circumferential side partition of the storage assembly 11 is defined between the adjacent two supports 21, and the limiting stopper 112 of at least one circumferential side partition is provided with a first notch 1120.

[0043] In the storage device 1 provided by the present application, the frame is used to support the storage assembly 11, so as to realize the spaced arrangement of the plurality of storage assemblies 11 along the first direction x. The accommodating cavity 10 for accommodating the articles is formed between the adjacent storage assemblies 11. Specifically, the storage assembly 11 comprises the partition plate 111 and the limiting stopper 112, and the adjacent partition plates 111 and the limiting stopper 112 located on the lower partition plate 111 jointly enclose the accommodating cavity 10. The partition plate 111 is used to carry the articles, and the limiting stopper 112 is connected with at least part of the circumferential edge of the partition plate 111. The plane where the limiting stopper 112 is located intersects the plane where the partition plate 111 is located. The limiting stopper 112 is used to limit the articles, so as to reduce the probability that the articles fall out of the accommodating cavity 10. The distance between the adjacent two partition plates 111 is greater than the size of the limiting stopper 112 along the first direction x, so that there is a gap between one of the adjacent two partition plates 111 and the limiting stopper 112 located on the other partition plate 111, and the gap serves as the access opening 12 for putting the articles into the accommodating cavity 10 or taking the articles out of the accommodating cavity 10, so as to facilitate the user to access the articles. The frame comprises a plurality of supports 21, which are arranged in a spaced manner along the circumferential edge of the partition plate 111 and are connected with the partition plate 111. The support 21 supports the partition plate 111, so as to realize the spaced arrangement of the adjacent partition plates 111. One circumferential side partition of the storage assembly 11 is defined between the adjacent two supports 21, and the limiting stopper 112 of at least one circumferential side partition is provided with a first notch 1120. The user can conveniently take the articles from the first notch 1120, so as to prevent the too small access opening 12 from affecting the taking speed of the articles. The structure of the storage device 1 is simple and convenient to access. No overall or independent locking element is arranged, and the limiting function of the articles can be realized only by the limiting stopper 112, so that the access time can be saved.

[0044] The storage device 1 can be applied in a low temperature environment, for example, can be placed in a liquid nitrogen environment, and is used for storing a cell freezing box. That is, the article in the containing cavity 10 can be a cell freezing box. Since the storage device 1 can save the time for accessing, the time for exposing the article in the air can be reduced, and the storage quality of the article can be improved.

[0045] In the above embodiment, since the storage device 1 does not have a whole locking element, and each containing cavity 10 does not have an independent locking element, the operation of unlocking and locking is saved. Since the locking element is not arranged, the whole storage device 1 does not need to be taken out from the liquid nitrogen tank, and only the target layer needs to be lifted to the position of the liquid nitrogen tank opening, so that the time for exposing the storage device 1 in the external environment is greatly shortened.

[0046] Specifically, the access opening 12 and the circumferential side zone corresponding to the first notch 1120 are arranged along the first direction x. The positions of the first notches 1120 of different storage assemblies 11 can be different, that is, the first notches 1120 of different storage assemblies 11 can be located in circumferential side zones in different directions.

[0047] Preferably, the positions of the first notches 1120 of different storage assemblies 11 are the same, so that the access to the article can be realized from the same side of different storage assemblies 11, and the operation time can be further saved.

[0048] In the above embodiment, the first notch 1120 exposes part of the surface of the article in the containing cavity 10 towards the first notch 1120, so that the article can be easily grabbed by fingers or tools, and the article can be easily taken out.

[0049] Specifically, the plurality of storage assemblies 11 are arranged at intervals along the first direction x, and the angles of the different storage assemblies 11 are the same. That is, between any two adjacent partitions 111, only the limiting stop piece 112 on one of the partitions 111 extends between the two partitions. The storage device 1 comprises a first side and a second side arranged along the first direction x, and the limiting stop piece 112 on each partition 111 extends towards the direction of the first side, so that between the two adjacent partitions 111, the limiting stop piece 112 on the one closer to the second side extends towards the two partitions 111, and the article is placed on the surface of the partition 111 closer to the second side away from the second side. Between the two adjacent partitions 111, the limiting stop pieces 112 on the one closer to the first side and the one closer to the second side form an access opening 12 for realizing the access to the article.

[0050] Specifically, when the storage device 1 is applied, the first direction x is a direction perpendicular to the ground, the first side is a top side away from the ground, and the second side is a bottom side close to the ground.

[0051] In the above embodiment, the storage device 1 further comprises a top plate 4, one of the plurality of storage assemblies 11 away from the second side is a preset storage assembly 11, and the top plate 4 is located on the side of the preset storage assembly 11 away from the second side and is spaced apart, so that the accommodation cavity 10 is formed between the top plate 4 and the preset storage assembly 11.

[0052] In the above embodiment, the support 21 can extend along the first direction x, and each support 21 is fixed with the plurality of storage assemblies 11 respectively.

[0053] In the above embodiment, the circumferential side partition is the part of the limiting stop 112 located between two adjacent supports 21.

[0054] In the above embodiment, the side of the top plate 4 away from the storage assembly 11 is provided with a numbering component and / or a label component 32 and / or a handle 31, and the numbering component and the label component 32 are fixed with the top plate 4 respectively, which can be fixed by adhesion.

[0055] Specifically, the numbering component is used for numbering the storage device 1, and the label component 32 is used for making remarks on the storage device 1. The number on the numbering component can match the liquid nitrogen tank slot position to prevent misplacement; the label component 32 facilitates the user to mark and manage different storage devices 1. The handle 31 is used to realize the taking of the storage device 1, so as to facilitate the user to take and place the storage device 1 in the liquid nitrogen tank.

[0056] Specifically, the numbering component and the label component 32 can respectively include a card slot, so as to facilitate the insertion and fixation of a numbering card and a label card.

[0057] Specifically, each storage assembly 11 is provided with an independent numbering area 33, which facilitates quick positioning of the target storage assembly 11 during storage and retrieval operations, and helps to improve the accuracy of taking. The independent numbering area 33 can be located on the baffle assembly, and the forming method can be engraving to form independent numbers on the independent numbering area 33, or using stickers, markers, etc. to set independent numbers on the independent numbering area 33.

[0058] In a feasible embodiment, as shown in Figure 1 In the storage assembly 11, the first notch 1120 extends from the side of the limiting stop 112 close to the partition 111 to the side of the limiting stop 112 away from the partition 111.

[0059] In the above embodiment, in one storage assembly 11, the first notch 1120 is provided through from the side close to the limiting stop 112 to the side away from the limiting stop 112, so as to facilitate the bottom of the article to provide a force away from the partition 111 to lift and take out the article. During the taking-out process, the article can be moved along the first notch 1120 away from the partition 111 to be taken out from the access opening 12.

[0060] In an implementation, as shown in Figure 1 The storage assembly 11 comprises a first circumferential partition, and the limiting stopper 112 in the first circumferential partition comprises a first baffle 1121 and a second baffle 1122, the first baffle 1121 and the second baffle 1122 are arranged along the extension direction of the edge of the partition plate 111, and the first gap 1120 is located between the first baffle 1121 and the second baffle 1122.

[0061] In the above implementation, the two support members 21 define a first circumferential partition, and the limiting stopper 112 in the first circumferential partition comprises a first baffle 1121 and a second baffle 1122, and the first gap 1120 is formed between the first baffle 1121 and the second baffle 1122. Specifically, the first gap 1120 is formed near the middle position of the first circumferential partition, thereby facilitating the storage operation of the articles.

[0062] In another implementation, the limiting stopper 112 in the first circumferential partition can only comprise a first baffle 1121, and the first gap 1120 is formed between the first baffle 1121 and the adjacent support member 21.

[0063] In an implementation, as shown in Figure 1 The plurality of support members 21 comprises a first support member 211 and a second support member 212, and the first support member 211 and the second support member 212 define a first circumferential partition, the first baffle 1121 is connected to the first support member 211, and the second baffle 1122 is connected to the second support member 212.

[0064] In the above implementation, the first support member 211 and the second support member 212 are arranged adjacent to each other along the circumferential direction of the partition plate 111.

[0065] In the above implementation, the first baffle 1121 is connected to the first support member 211, and the second baffle 1122 is connected to the second support member 212, thereby improving the total coverage range of the first baffle 1121 and the second baffle 1122 along the circumferential direction of the partition plate 111, and better blocking the articles located in the accommodation cavity 10.

[0066] In an implementation, as shown in Figure 1 The plane where the limiting stopper 112 is located and the plane where the partition plate 111 is located are at a right angle. Thereby, the compactness of the storage device 1 and the larger space of the accommodation cavity 10 can be considered.

[0067] In the above implementation, the included angle between the plane where the limiting stopper 112 is located and the plane where the partition plate 111 is located can also be an obtuse angle or an acute angle, which can also play a limiting role.

[0068] In an embodiment, as shown in FIG. 1, the partition 111 is provided with a second notch 1110 corresponding to the first notch 1120, and the first notch 1120 and the second notch 1110 are in communication. Figure 2

[0069] In the above embodiment, the second notch 1110 is formed by recessing the edge of the partition 111 inward, and specifically, the second notch 1110 is formed by recessing the edge of the partition 111 opposite to the first notch 1120 inward.

[0070] In the above embodiment, the second notch 1110 is formed by recessing the edge of the partition 111 inward, and specifically, the second notch 1110 is formed by recessing the edge of the partition 111 opposite to the first notch 1120 inward.

[0071] In an embodiment, as shown in FIG. 1, the partition 111 is provided with a second notch 1110 corresponding to the first notch 1120, and the first notch 1120 and the second notch 1110 are in communication. Figure 2

[0072] In the above embodiment, the second notch 1110 is formed by recessing the edge of the partition 111 inward, and specifically, the second notch 1110 is formed by recessing the edge of the partition 111 opposite to the first notch 1120 inward.

[0073] In an embodiment, as shown in FIG. 1, the partition 111 is provided with a second notch 1110 corresponding to the first notch 1120, and the first notch 1120 and the second notch 1110 are in communication. Figure 2

[0074] In the above embodiment, the second notch 1110 is formed by recessing the edge of the partition 111 inward, and specifically, the second notch 1110 is formed by recessing the edge of the partition 111 opposite to the first notch 1120 inward.

[0075] Specifically, the length of the major axis of the ellipse is 3-6 cm, so as to stretch in 2-4 fingers, so as to improve the contact area between the fingers and the article or the tool and the article, thereby improving the stability of taking the article. The length of the minor axis is 2-5 cm, so as to further improve the contact area between the article and the fingers / tool.

[0076] In an embodiment, as shown in FIG. 1, the partition 111 is provided with a second notch 1110 corresponding to the first notch 1120, and the first notch 1120 and the second notch 1110 are in communication.​​​Figure 2 As shown, the support 21 comprises a strip-shaped support plate, the partition plate 111 is in a rectangular shape, the rectangular shape comprises two opposite first sides C1 and two opposite second sides C2, the strip-shaped support plate is connected to the first side C1 and close to the four right-angle positions of the rectangular shape, and the first notch 1120 is located at the peripheral side partition where the second side C2 is located.

[0077] In the above embodiment, the peripheral side partition where the first notch 1120 is located can be used to take the articles located in the accommodation cavity 10, therefore, the support plate is not fixed with the second side C2 to avoid blocking the access opening 12 and affecting the taking of the articles or affecting the utilization rate of the space in the accommodation cavity 10. The support plate is fixed with the first side C1, which can block the articles on both sides of the first side C1 to further limit the articles in the accommodation cavity 10.

[0078] In a feasible embodiment, the limiting stopper 112 has an integrated structure with the partition plate 111.

[0079] In the above embodiment, the limiting stopper 112 and the partition plate 111 can be integrally formed by using the same material, thereby improving the overall strength and saving the process of fixing the two, that is, simplifying the structure and preparation process.

[0080] Specifically, the materials of the limiting stopper 112, the partition plate 111, the support 21 and the support plate can all be stainless steel or other metal materials resistant to liquid nitrogen low temperature.

[0081] In a feasible embodiment, as shown in Figure 3 and Figure 4 each peripheral side partition is provided with a limiting stopper 112.

[0082] In the above embodiment, by providing the limiting stopper 112 in each peripheral side partition, the articles in the accommodation cavity 10 can be blocked in each peripheral side partition to prevent the articles from escaping from the accommodation cavity 10 through any peripheral side partition.

[0083] Alternatively, as shown in Figure 2 and Figure 5 the frame further comprises a connecting plate 22 extending along the first direction x, the limiting stopper 112 is arranged on the first side C1, one of the limiting stoppers 112 is arranged on one of the second sides C2, and the other second side C2 is connected with the connecting plate 22.

[0084] In the above embodiment, the frame further comprises a connecting plate 22, the connecting plate 22 extends along the first direction x and extends from the first side to the second side of the storage device 1, and the connecting plate 22 is connected with each partition plate 111. The connecting plate 22 is connected with the second side C2 to limit the articles in the accommodation cavity 10.

[0085] In one feasible implementation, such as Figure 5 As shown, the dimension of the connecting plate 22 along the length direction of the second side C2 is less than or equal to the length of the second side C2.

[0086] Specifically, the dimension of the connecting plate 22 along the length direction of the second side C2 is less than or equal to the length of the second side C2, thereby saving material costs and facilitating processing and manufacturing; and it allows tools / fingers to come into contact with the items in the receiving cavity 10 from both sides of the connecting plate 22, thereby pushing the items so that they can be picked up from the first notch 1120.

[0087] In one feasible implementation, such as Figure 2 As shown, the receiving cavity 10 is used to receive the box body, the thickness of the box body is a first thickness, the spacing between the partitions 111 is a first spacing, and the dimension of the limiting stop 112 along the first direction x is a first dimension. The relationship between the first dimension, the first thickness, and the first spacing is as follows:

[0088] W = H + L + a, where the first dimension is L, the first thickness is H, the first spacing is W, and 0.5cm ≤ a ≤ 1cm.

[0089] In the above embodiments, the box can be a cryopreservation box.

[0090] In the above embodiment, a sufficient first gap is reserved between adjacent partitions 111 to facilitate the retrieval of the box.

[0091] Specifically, when the box is placed into the receiving cavity 10, it is necessary to ensure that the distance between the box and the upper partition 111 when the box is raised to the limiting stop 112 is 0.5cm to 1cm, so that the box can be picked up with fingers or tools, thereby further saving the time spent storing and retrieving items.

[0092] Specifically, the first dimension can be 1cm to 3cm. The first spacing can be 6.8cm to 8.8cm. The first thickness can be 5.2cm.

[0093] In one feasible implementation, such as Figure 6 As shown, the storage device 1 also includes an anti-slip layer 23, which is disposed on at least a portion of the partition 111 facing the receiving cavity 10.

[0094] In the above embodiment, by providing an anti-slip layer 23 on the surface of the partition 111 facing the receiving cavity 10, the stability of the item after it is stored in the receiving cavity 10 can be improved, the probability of the item sliding in the receiving cavity 10 can be reduced, thereby protecting the item and reducing the probability of the item moving due to the movement of the storage device 1.

[0095] Specifically, the anti-slip layer 23 can be provided only on the side surface of the partition 111 that is in contact with the item, thereby saving costs and increasing the space within the receiving cavity 10.

[0096] In one feasible implementation, the anti-slip layer 23 is made of at least one of silicone or felt.

[0097] In one feasible implementation, such as Figure 7 As shown, the limiting stop 112 includes an elastic reset member 1123, which can be extended and retracted along a second direction, and the second direction intersects with the plane where the partition 111 is located.

[0098] In the above embodiment, the limiting stop 112 adopts an elastic reset member 1123, which can be compressed when picking up or storing an item to increase the size of the access opening 12, thereby allowing the item to be placed into or removed from the receiving cavity 10. After storage or retrieval is completed, the elastic reset member 1123 resets to block and limit the item. Since the elastic reset member 1123 can only extend and retract along the second direction, which intersects the plane where the partition 111 is located, it can provide resistance to the item parallel to the direction where the partition 111 is located after it resets, thereby limiting the item.

[0099] In the above embodiments, since the access port 12 can be enlarged by compressing the elastic reset member 1123, the space occupied by the elastic reset member 1123 on the access port 12 can be ignored, thereby reducing the distance between adjacent partitions 111 along the first direction x, so as to improve the compactness of the storage device 1.

[0100] The top of the cryogenic racks has pre-set numbers and labels. The numbers match the liquid nitrogen tank slots to prevent misplacement. The labels allow users to easily mark and manage different cryogenic racks. Each storage compartment has a unique number, facilitating quick location of the target compartment during access operations and preventing mistakes.

[0101] This application also provides a refrigeration device (not shown in the figure), including a freezing container and any of the storage devices in the above embodiments, wherein the freezing container is provided with a freezing chamber and the storage device is disposed in the freezing chamber.

[0102] Specifically, the freezing container can be a liquid nitrogen tank with a freezing chamber, and the storage device can be placed inside the freezing chamber to freeze and preserve the items contained in the storage device.

[0103] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
