Description

Technical Field

[0001] The utility model relates to the technical field of freezing storage, in particular to a simple freezing and heat preservation device for a freezing storage box. Background Art

[0002] During the ultra-low temperature transfer of samples, the samples need to be placed in a cryopreservation box and then transported through a dry ice cold chain. After being transferred to the destination, the recipient scans the code to confirm the sample. To ensure the safety of the samples, the backup samples need to be stored in different refrigerators as much as possible. During the experiment, the samples are sorted from the refrigerator and collected in batches.

[0003] However, during the ultra-low temperature transfer of samples, the cold chain transportation link may cause the cryobox to be bumped to the surface of the dry ice due to bumps, which will affect the freezing effect of the samples stored in the cryobox, and the lid of the cryobox may even fall off. Therefore, rubber bands or tapes must be used during transportation to reinforce the cryobox to prevent the lid from opening.

[0004] In addition, the operation of scanning the code to confirm the sample or sorting the sample needs to be carried out in an ultra-low temperature environment. The traditional method is to put the cryobox in a foam box or other container filled with dry ice, wrap the cryobox with dry ice as much as possible, and then use a barcode scanner to scan the code one by one to confirm the sample or sort the sample. In this process, when the container and the cryobox are inconsistent, the utilization rate of the effective insulation area is low (for example, the container area is 80, but the cryobox can only use 50), which takes up more site space. In addition, in this scanning confirmation or sorting method, the cryobox needs to be fully wrapped with dry ice by manual burial, which not only wastes manpower, but also consumes a large amount of dry ice, and the freezing and insulation effect is limited. Summary of the invention

[0005] In view of the problems that during the ultra-low temperature transfer of samples loaded in the cryogenic boxes of the prior art, the freezing effect is easily affected by bumps, and the scanning code confirmation or sorting process wastes manpower and is inconvenient to operate, the purpose of the utility model is to provide a simple freezing and heat preservation device for cryogenic boxes, so as to at least partially solve the above problems.

[0006] To achieve the above purpose, the technical solution of the utility model is:

[0007] A simple freezing and heat preservation device for a freezing box, comprising a base, a box frame and a cover; a concave cavity is provided on the top surface of the base; the box frame is located in the concave cavity, the box frame comprises a box frame body, a freezing box placement position for placing a freezing box is provided on the top surface of the box frame body, the bottom surface of the box frame body is fixedly connected to the base through a plurality of pillars, and a hollow hole opposite to the freezing box placement position is also provided on the box frame body; the cover is detachably fixedly connected to the top surface of the base to close the concave cavity.

[0008] In a preferred embodiment, the pillar is detachably fixedly connected to the base by screws, wherein the bottom of the cavity is provided with a through hole adapted to the screw, and the bottom surface of the pillar is provided with a threaded hole adapted to the screw.

[0009] In a preferred embodiment, the freezing box placement position is configured as a sunken groove opened on the top surface of the box rack body, and the sunken groove is adapted to the freezing box to be frozen.

[0010] In a preferred embodiment, a circle of enclosure arranged around the sunken groove is fixedly provided on the top surface of the box frame body.

[0011] In a preferred embodiment, the distance from the top surface of the box rack body to the top surface of the base is greater than or equal to the thickness of the cryopreservation box to be frozen.

[0012] In a preferred embodiment, it also includes a hollow frame compressed between the cover and the base, the hollow frame includes an annular rim, the top surface of the base and the bottom surface of the cover are both provided with an embedding groove adapted to the annular rim, and the embedding groove opened on the top surface of the base is arranged around the concave cavity.

[0013] In a preferred embodiment, the hollow frame further comprises a sub-grid fixedly arranged on the inner side of the annular surrounding edge.

[0014] In a preferred embodiment, the sub-grids are in a cross shape.

[0015] In a preferred embodiment, the base, the cover and the hollow frame are all made of low-temperature resistant materials.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. Due to the arrangement of the base with the concave cavity, the box rack installed in the concave cavity and used to place the cryobox, and the cover detachably fixed relative to the base, during the sample transfer process, since the concave cavity is filled with dry ice and the concave cavity is covered by the cover, the dry ice in the concave cavity can be compressed, thereby tightly surrounding the cryobox. Therefore, even if some bumps occur during the sample transfer process, the cryobox will not move to the surface of the dry ice, thereby ensuring that the sample freezing effect is not affected by the bumps;

[0018] 2. Since the cryopreservation box is stored in the simple freezing and heat preservation device and is covered with dry ice, when scanning the code to confirm the sample or sorting the sample, it is sufficient to scan the code directly on the simple freezing and heat preservation device, without the need to prepare additional foam boxes and containers, or to cover the cryopreservation box with dry ice in containers such as foam boxes. In addition, the size of the simple freezing and heat preservation device and the stored cryopreservation box is easily adapted, so that the simple freezing and heat preservation device can obtain good effective insulation area utilization, reduce production consumables, and save dry ice.

[0030] Embodiment 1

[0031] like Figure 1-3 As shown, an embodiment of the utility model provides a simple freezing and heat preservation device for a cryopreservation box, comprising a base 1, a box frame 2 and a cover 3, for freezing and heat preservation of a cryopreservation box 4.

[0032] A concave cavity is formed on the top surface of the base 1 , for example, the base 1 is configured as a shell-like structure with an open top surface.

[0033] The box frame 2 is located in the concave cavity of the base 1. The box frame 2 includes a box frame body 21. The box frame body 21 is in a flat plate-like structure as a whole. Its shape matches the shape of the freezing box 4, but its size is larger than the size of the freezing box 4, and the size of the box frame body 21 is smaller than the size of the concave cavity. The top surface of the box frame body 21 is provided with a freezing box placement position for placing the freezing box 4. For example, the freezing box placement position is configured as a sunken groove opened on the top surface of the box frame body 21. The shape and size of the sunken groove are both adapted to the freezing box 4 to be frozen.

[0034] The box frame 2 also includes a plurality of pillars 22 fixedly arranged at the bottom surface of the box frame body 21, for example, four pillars 22 are respectively arranged at the four corners of the bottom surface of the box frame body 21, and the pillars 22 and the box frame body 21 are preferably integrally formed. The box frame 2 is fixedly connected to the base 1 through the pillars 22, for example, the pillars 22 are detachably fixedly connected to the base 1 through screws 23, wherein four through holes matching the screws 23 are provided at the bottom of the cavity, and threaded holes matching the screws 23 are provided on the bottom surface of the pillars 22. In this arrangement, not only can the box frame 2 be detachably fixed in the cavity of the base 1, but also a certain distance is provided between the box frame body 21 and the bottom of the cavity.

[0035] In addition, a circle of enclosures 24 arranged around the sunken groove is fixedly provided on the top surface of the box rack body 21. For example, the enclosures 24 are integrally formed on the box rack body 21. Through the setting of the enclosures 24, the frozen storage box 4 placed in the sunken groove will not fall off the box rack body 21 easily.

[0036] It is easy to understand that the concave cavity of the base 1 is used not only for placing the box rack 2, but also for accommodating a certain amount of dry ice, and the dry ice is used to freeze and keep warm the freezing box 4 placed on the box rack 2. Due to the arrangement of the support 22 at the bottom surface of the box rack 2, the dry ice can enter the position between the box rack 2 and the concave cavity, and then freeze the box rack 2 from the bottom side.

[0037] In order to further improve the freezing effect, a hollow hole opposite to and connected to the sinking groove is provided on the box frame body 21, so that the coldness of the dry ice can directly act on the bottom surface of the freezing box 4 through the hollow hole. Among them, only one hollow hole can be provided, and the hollow hole is configured to be located at the center of the sinking groove, and the size of the hollow hole is configured to be smaller than the sinking groove, so as to prevent the freezing box 4 from falling from the hollow hole. Of course, in other preferred embodiments, multiple hollow holes can be provided and configured to be smaller in size, and multiple hollow holes can be evenly distributed in the sinking groove.

[0038] The cover 3 is detachably fixedly connected to the top surface of the base 1, and when the cover 3 is fixedly connected to the base 1, the cover 3 also closes the cavity at the same time, thereby closing the box rack 2 and the cryopreservation box 4 placed thereon in the cavity. In this embodiment, two opposite sides of the cover 3 are movably connected with connecting plates 5, for example, pivotally connected by hinges, the pivot axis is parallel to the plane where the cover 3 is located, and the other end of the connecting plate 5 is connected to the base 1 by elastic buckles or screws. Of course, in other preferred embodiments, the cover 3 can also be configured to be directly fixedly connected to the base 1 by lock buckles or screws.

[0039] Since the cover 3 is directly covered on the base 1 from one side of the top surface, the top surface of the freezing box 4 placed on the box rack 2 must not protrude from the top surface of the base 1, that is, the distance from the top surface of the box rack body 21 (actually the bottom of the sunken groove) to the top surface of the base 1 is greater than the thickness of the freezing box 4 to be frozen. This, on the one hand, prevents the freezing box 4 from affecting the installation of the cover 3, and on the other hand, allows a distance between the freezing box 4 and the cover 3 that can accommodate dry ice, so that one side of the top surface of the freezing box 4 can also be covered with dry ice, thereby achieving all-round freezing.

[0040] It is also easy to understand that the base 1 and the cover 3 and other structures directly exposed to the outside are made of low-temperature resistant materials, thereby minimizing the rate at which the coldness of the dry ice is lost to the outside, thereby improving the freezing effect.

[0041] The use process of the simple freezing and heat preservation device for a freezing box provided by the embodiment of the utility model is as follows:

[0042] When in use, the sample is loaded into the freezing box 4, the freezing box 4 is placed on the box rack 2, and then the cavity of the base 1 is filled with dry ice, so that the bottom and top surfaces of the freezing box 4 are surrounded by dry ice, and then the cover 3 is covered and fixed on the top surface of the base 1, and the bottom and top surfaces of the freezing box 4 are surrounded by dry ice. During the sample transfer process, since the cavity is filled with dry ice and the cavity is covered by the cover 3, the dry ice in the cavity can be compressed, thereby tightly surrounding the freezing box 4. Therefore, even if some bumps occur during the sample transfer process, the freezing box 4 will not move to the surface of the dry ice, thereby ensuring that the sample freezing effect is not affected by the bumps.

[0043] Embodiment 2

[0044] Based on the first embodiment, Figure 4-6 As shown, the simple freezing and heat preservation device for the freezing box provided in this embodiment further includes a hollow frame 6 compressed between the cover 3 and the base 1, and the hollow frame 6 is also made of low-temperature resistant material.

[0045] The hollow frame 6 includes an annular rim 61 made of low-temperature resistant material, which is formed by a long strip of plate surrounding a circle. Its shape is consistent with the shape of the cavity and its size is larger than that of the cavity. The annular rim 61 is arranged around the cavity.

[0046] The top surface of the base 1 and the bottom surface of the cover 3 are both provided with an embedding groove matched with the annular rim 61 , so that the annular rim 61 can be firmly pressed between the cover 3 and the base 1 .

[0047] Among them, the space enclosed by the annular edge 61, the cover 3 and the base 1 is also used to fill dry ice, so that more dry ice is arranged on one side of the top surface of the freezing box 4 placed on the box rack 2, thereby better avoiding that the dry ice on one side of the top surface of the freezing box 4 cannot completely cover the freezing box 4 due to bumps.

[0048] It is easy to understand that in order to further prevent the dry ice on the top surface of the freezing box 4 from being concentrated and accumulated due to bumps, the hollow frame 6 also includes a sub-grid 62 fixedly arranged on the inner side of the annular edge 61. For example, the material of the sub-grid 62 is the same as that of the annular edge 61 and the two are integrally formed. In this embodiment, the sub-grid 62 is configured in a cross shape. Of course, in other preferred embodiments, the sub-grid 62 can also be other shapes.

[0049] It is easy to understand that due to the provision of the hollow frame 6, there is enough space on the top surface of the freezing box 4 to load dry ice, and when the hollow frame 6 is pressed between the cover 3 and the base 1, the hollow frame 6 can also clamp the freezing box 4 to prevent the cover of the freezing box 4 from falling off. Therefore, in a preferred embodiment, the distance from the top surface of the box frame body 21 (actually the bottom of the sunken groove) to the top surface of the base 1 can be configured to be equal to the thickness of the freezing box 4 to be frozen, which can reduce the thickness requirement of the base 1.

[0050] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
