Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature storage, and in particular to an automatic low-temperature storage device. Background Art

[0002] At present, with the widespread application of biomedicine and university scientific research technology, the demand for ultra-low temperature freezer storage boxes for storing reagents and samples is increasing. The safety requirements for experiments are becoming more and more stringent, and safety issues have become a matter of great concern. Laboratories often use low-temperature storage equipment to store items at low temperatures. The main items used to store include: storing cell line materials, blood, tissues, organs, seeds, and other reagents that need to be stored at low temperatures.

[0003] The cryogenic storage equipment currently on the market usually places the cryobox containing biological samples in a cryorack, and then places the cryorack in a low-temperature space. When you need to take or place a sample, you only need to take or place the cryorack. In the prior art, electromagnetic lock adsorption is generally used to take or place the cryorack. However, the current performance technology of the electromagnet adsorption method can only be performed at -20°C. For the safety of the samples, the samples need to be kept in a low temperature environment of -80°C or above. In addition, when the cryorack is transferred from -80°C to a normal temperature environment, the lining is prone to frost and ice, which affects the return of the cryorack. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 , Figure 2 and Figure 5 The utility model provides an automated low-temperature storage device, comprising:

[0026] The freezing frame 1 has a receiving cavity 12 evenly arranged in the middle of the upper portion and mounting cavities 11 arranged at both ends;

[0027] A door panel 4 is arranged above the freezing frame 1;

[0028] The freezing rack 2 is arranged in the accommodating chamber 12, and the top end is connected to the door panel 4;

[0029] The lifting module 3 is disposed in the installation cavity 11 , and the output end thereof is connected to the door panel 4 , and is used for taking and placing the freezing rack 2 .

[0030] In the utility model, by adopting magnetic connection under conventional environment, the technical barrier that magnetic connection cannot be used in low temperature environment of -80°C is broken, and the stability of the freezing rack during the taking and placing process is ensured, which not only ensures the safety of the samples but also increases the service life of the freezing rack.

[0031] Specifically, the freezing frame 1 is a cut-out outlet of the freezing rack module, which reduces the problem of the entire freezing rack 2 being pulled out quickly and exposed to cold.

[0032] Preferably, in order to ensure the long-term use of the freezing frame 1, the material of the bottom that contacts the low-temperature environment must be a material that is resistant to low temperatures and has good cold conductivity, rather than a general plastic material.

[0033] In one embodiment, see Figure 3 The freezing rack 2 includes a frame 26, in which equidistantly distributed freezing layers 24 are arranged. The freezing layers 24 and the frame 26 are in a pull-out sliding fit. A foam layer 22 is provided at the top of the frame 26, and a sealing plate 25 is provided at the top of the foam layer 22. A magnetic suction module 21 connected to the door panel 4 is provided on the sealing plate 25.

[0034] This embodiment is configured in such a way that, in order to use the magnetic attraction technology and break the technical barrier that the magnetic attraction cannot be used in a low temperature environment of -80°C, the magnetic attraction module 11 is placed in a room temperature environment, and the freezing rack 1 is added with an insulation module, namely, a foaming layer 12, to ensure the safety of the sample.

[0035] In one embodiment, see Figure 4 The lifting module 3 includes a screw rod 31, which is arranged through the bracket 35 and driven by a motor 32. In this embodiment, the motor 32 is powered to push the screw rod 31 to a required height, thereby driving the freezing rack 2 to be moved out of the freezing frame 1.

[0036] In one embodiment, guide rods 33 connected to the door plate 4 are provided on both sides of the screw rod 31, the guide rods 33 are arranged through the bracket 35, and the connection is connected by a bearing 34. In this embodiment, the stability of the freezing rack 2 can be ensured by using four guide rods 33 on both sides.

[0037] In one embodiment, a protective cover 5 is further included, which is arranged on the top of the freezing frame 1 and connected to the door panel 4. In this embodiment, the power connection module connected to the magnetic suction module 21 is protected by the protective cover 5 to make the wires wear-resistant for a long time. Specifically, the protective cover 5 can be a tank chain.

[0038] In one embodiment, a forward convex handle 23 is provided at the end of the freezing layer 24. This embodiment is arranged so that the freezing layer 24 can be pulled out after the freezing shelf 2 is lifted out, wherein the forward convex handle 23 and the freezing layer 24 are welded, which is more solid and reliable.

[0039] See also Figure 3 , a configuration of the magnetic suction module 21 is given, at least two magnetic suction modules 21 are provided, and they are symmetrically distributed at the top of the sealing plate 25. It should be noted that one magnetic suction module 21 can also be provided. In this embodiment, the stability of the lifting freezing rack 2 during movement can be improved through the symmetrical magnetic suction module 21.

[0040] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes that satisfy both A and B. In addition, "multiple" refers to more than two. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist.
