Biological samples are generally stored in low-temperature refrigerators or low-temperature storage devices such as liquid nitrogen tanks, and the freezing rack is one of the important structures in the low-temperature storage device, mainly used for placing sample test tubes or sample test tube turnover boxes, etc.

[0003] The comparative document with the patent publication number of CN221091686U discloses a detachable freezing rack for sample storage, which realizes the flexible use of short-section freezing racks through the detachable connection between short-section freezing racks, thereby improving work efficiency and increasing the storage capacity of samples. However, due to the relatively complex detachable connection relationship between its two freezing racks, the combination and disassembly between the two freezing racks are responsible for the connection locking component, and the connection locking component has a complex structure, resulting in a high cost. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a detachable freezing rack for sample storage, in which the connection relationship between two mutually adapted freezing racks for combination and disassembly is relatively simple and easy to operate, thus reducing the cost.

[0012] Further, two first handles are provided at the top of the frame, and the two first handles are respectively oppositely arranged on the first horizontal side and the second horizontal side; the split cryogenic storage rack for sample storage further includes a first rectangular sleeve frame, and the first rectangular sleeve frame is used for sleeving the two first handles of two adjacent said frames.

[0013] Further, the bending strength of the first rectangular sleeve frame is greater than the bending strength of the first handle.

[0014] Further, the first handle has a first holding through hole.

[0015] Further, a plurality of the first rectangular bosses are provided on opposite sides of the first horizontal side of the frame; a plurality of the second rectangular bosses are provided on opposite sides of the second horizontal side of the frame.

The first rectangular boss of one of them cooperates with the second rectangular embedding groove of the other, and the first rectangular embedding groove of one of them cooperates with the second rectangular boss of the other, so that the two frames are mutually limited in the vertical direction, and the cooperation and disengagement methods are relatively simple, easy to operate, and time-consuming. In addition, after two adjacent frames are cooperated, if one of them is lifted, the other is also lifted accordingly. This not only enables multiple frames to be transferred together at the same time, but also one of them can be taken away separately after the cooperation relationship is released, making the use more flexible. In addition, since all the bearing cavities of one of the two adjacent frames are blocked by the second horizontal side of the other frame, the baffle is used to block the bearing cavities on the frame that have not been blocked, so that only one baffle is needed, and multiple frames can use other frames to block their bearing cavities, saving the number of baffles, and making multiple frames fit tightly together, increasing the space utilization rate and expanding the storage space. It can be understood that due to the simple cooperation relationship between the two frames, the cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] See Figures 1 - 3 , a detachable freezing rack for sample storage according to a preferred embodiment of the present utility model, comprising a plurality of racks 1 and baffles 2.

[0031] The rack 1 is provided with a plurality of loading cavities 11 arranged at intervals in the vertical direction. The loading cavities 11 are used for accommodating sample reagent kits. During storage, after placing a plurality of sample reagent kits into one of the loading cavities 11 respectively, the rack 1 can be placed into a low-temperature storage device such as a low-temperature refrigerator or a liquid nitrogen tank for storage.

[0032] The first horizontal side 12 of the rack 1 is provided with a plurality of first rectangular bosses 13, and the plurality of first rectangular bosses 13 are arranged at intervals in the vertical direction (i.e., the height direction) so as to form a first rectangular embedding groove 14 between two first rectangular bosses 13.

[0033] The second horizontal side 15 of the rack 1 is arranged opposite to the first horizontal side 12. The second horizontal side 15 of the rack 1 is provided with a plurality of second rectangular bosses 16, and the plurality of second rectangular bosses 16 are arranged at intervals in the vertical direction so as to form a second rectangular embedding groove 17 between two second rectangular bosses 16.

[0034] The entrance and exit 111 of the loading cavity 11 is located on the first horizontal side 12 of the rack 1. The entrance and exit 111 is used for allowing the sample reagent kit to enter the loading cavity 11 and for allowing the sample reagent kit to be taken out from the loading cavity 11.

[0035] A row of frames 1 are connected in sequence along the horizontal direction. Among two adjacent frames 1, the first rectangular boss 13 of one is adapted to the second rectangular embedding groove 17 of the other; the first rectangular embedding groove 14 of one is adapted to the second rectangular boss 16 of the other, so that the two adjacent frames 1 can be spliced ​​together along the horizontal direction, and all the bearing cavities 11 of one of the two adjacent frames 1 are blocked by the second horizontal side 15 of the other frame 1, and the baffle 2 is used to block the bearing cavities 11 on the frame 1 that have not been blocked.

[0036] In this way, when any two adjacent frames 1 are taken, the first rectangular boss 13 of one of them is matched with the second rectangular embedding groove 17 of the other, and the first rectangular embedding groove 14 of one of them is matched with the second rectangular boss 16 of the other, so that the two frames 1 are mutually limited in the vertical direction, and the matching and releasing methods are relatively simple, easy to operate, and time-consuming. In addition, after the two adjacent frames 1 are matched, if one of them is lifted, the other is also lifted together, not only can multiple frames 1 be transferred together at the same time, but also one of them can be taken away separately after the matching relationship is released, which is more flexible to use. In addition, since all the bearing cavities 11 of one of the two adjacent frames 1 are blocked by the second horizontal side 15 of the other frame 1, the baffle 2 is used to block the bearing cavities 11 on the frame 1 that have not been blocked, so that only one baffle 2 is needed, and multiple frames 1 can use other frames 1 to block their bearing cavities 11, saving the number of baffles 2, and making multiple frames 1 closely fit together, increasing space utilization and expanding storage space. It can be understood that since the matching relationship between the two frames 1 is simple, the manufacturing cost is reduced.

[0037] In this embodiment, preferably, two first handles 18 are provided at the top of the frame body 1, and the two first handles 18 are respectively disposed opposite to each other on the first horizontal side 12 and the second horizontal side 15; a detachable cryogenic storage rack for sample storage further includes a first rectangular sleeve 3, and the first rectangular sleeve 3 is used to sleeve the two first handles 18 of two adjacent frame bodies 1. With this setting, after the first rectangular sleeve 3 sleeves the two first handles 18, two adjacent frame bodies 1 support each other and it is difficult to tip over. Moreover, when one of the frame bodies 1 is lifted, due to the cooperation of the first rectangular boss 13 of one of the two adjacent frame bodies 1 with the second rectangular embedding groove 17 of the other, and the cooperation of the first rectangular embedding groove 14 of one of them with the second rectangular boss 16 of the other, the two frame bodies 1 are limited in the vertical direction to each other. And because the first rectangular sleeve 3 forces the two frame bodies 1 to be limited in the horizontal direction to each other, that is, the two frame bodies 1 are completely limited to each other. Under the locking of the self-weight of the first rectangular sleeve 3 downward, it is ensured that the two frame bodies 1 cannot be separated, and the stability of lifting multiple frame bodies 1 at the same time is guaranteed. And when it is necessary to release the locking relationship between the two frame bodies 1, only the weight of the first rectangular sleeve 3 needs to be overcome and it is taken out upward, then the two frame bodies 1 can be separated from each other in the horizontal direction, so that the first rectangular boss 13 of one of the two frame bodies 1 is separated from the second rectangular embedding groove 17 of the other, and the first rectangular embedding groove 14 of one of them is separated from the second rectangular boss 16 of the other. The contact method is simple, fast and easy.

[0038] In this embodiment, preferably, the bending strength of the first rectangular sleeve 3 is greater than that of the first handle 18. With this setting, the first rectangular sleeve 3 is not a vulnerable part, thus avoiding the phenomenon that the frame body 1 falls off when lifting and transferring multiple frame bodies 1 at the same time. It can be understood that the first handle 18 is a part of the frame body 1 and is not easily directly broken, but more often shows a bending phenomenon. By ensuring the safety of the first rectangular sleeve 3, the phenomenon that the frame body 1 directly falls during the transfer process can be avoided.

[0039] In this embodiment, preferably, the first handle 18 has a first holding through hole 181. Among them, the first holding through hole 181 can be used for the operator to directly hold to transfer a single frame body 1. The first holding through hole 181 can also be used for an operating rod to be inserted to transfer multiple frame bodies 1 in batches.

[0040] In this embodiment, in order to improve the cooperation stability between the two frame bodies 1, preferably, a plurality of first rectangular bosses 13 are provided on opposite sides of the first horizontal side 12 of the frame body 1; a plurality of second rectangular bosses 16 are provided on opposite sides of the second horizontal side 15 of the frame body 1.

[0041] In this embodiment, in order to improve the connection stability between the baffle 2 and the frame body 1, preferably, a plurality of third rectangular bosses 21 are provided on both horizontal opposite sides of the baffle 2, and the third rectangular bosses 21 are adapted to cooperate with the first rectangular embedding grooves 14. By embedding the plurality of third rectangular bosses 21 into the plurality of first rectangular embedding grooves 14 one by one, the blocking stability of the baffle 2 for the plurality of bearing cavities 11 of the frame body 1 is improved.

[0042] In this embodiment, similarly to the first handle 18, preferably, a second handle 22 is provided on the top of the baffle 2; a detachable cryogenic storage rack for sample storage further includes a second rectangular sleeve, and the second rectangular sleeve is used to sleeved the second handle 22 and the first handle 18 of the adjacent frame body 1 together. The second handle 22 facilitates the operator to take the baffle 2, and, the second handle 22 can be inserted by an operating rod.

[0043] In this embodiment, preferably, three shielding convex edges 19 are provided on the horizontal side of the bearing cavity 11, and the upper part of the shielding convex edge 19 is a hollow structure 191. The shielding convex edge 19 is used to prevent the sample kit from detaching from the bearing cavity 11 in the horizontal direction. With this setting, not only the sample kit is limited by the shielding convex edge 19, but also the upper part of the shielding convex edge 19 is hollowed out, so that the operator can observe the internal conditions of each bearing cavity 11 in all directions, so as to judge whether there is a sample kit in the bearing cavity 11 and observe the state of the sample kit.

[0044] In this embodiment, in order to make the structure of the frame body 1 more compact, preferably, the frame body 1 is in a cuboid structure. In this way, when a plurality of frame bodies 1 are pieced together, the space utilization rate is further improved.

[0045] In this embodiment, in order to improve the storage stability of the frame body 1, preferably, the bottom of the frame body 1 is a flat structure.

[0046] The above embodiments are only the preferred embodiments of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
