Description

Technical Field

[0001] This utility model relates to the field of biological sample storage equipment technology, specifically a cryopreservation rack with anti-freezing guide rails and identification structure. Background Technology

[0002] Cryogenic racks, as support structures for sample box storage, are often used in liquid nitrogen tanks or ultra-low temperature freezers to ensure that the items are evenly distributed in a low-temperature environment, maintain uniform and stable temperature in all parts, and preserve the activity and quality of the items.

[0003] Currently, most cryopreservation racks used in laboratories are flat-panel structures. When the cryopreservation racks are placed directly in liquid nitrogen tanks or ultra-low temperature freezers, the bottom of the base plate used to limit the cryopreservation boxes inside the cryopreservation rack and the contact surface are prone to freezing and sticking together, making it difficult to pull out and reducing the efficiency of sampling. In addition, when multiple cryopreservation boxes are stacked in the existing cryopreservation racks, there is a lack of orderly markings, resulting in low sample positioning efficiency.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a cryopreservation rack with an anti-freeze guide rail and an identification structure, so as to solve the problems mentioned in the background art, such as the contact surface of the bottom cryopreservation rack, which is used to limit the cryopreservation box, is prone to freezing and sticking, making it difficult to pull out, and the lack of orderly marking of the cryopreservation box in the cryopreservation rack, resulting in low sample positioning efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A cryogenic rack with anti-freeze guide rails and an identification structure includes a cryogenic rack body and further includes:

[0008] The storage component includes a base plate that is slidably disposed within the body of the cryopreservation rack for supporting and limiting the cryopreservation box, and a bracket disposed at the lower end of the base plate for reducing the contact area between the base plate and the body of the cryopreservation rack.

[0009] The identification structure includes serial number markings on both sides of the base plate for identifying individual cryopreservation boxes, and label slots on the base plate at the opening of the cryopreservation box for classifying and marking each layer of the base plate.

[0010] Furthermore, a front baffle is fixedly connected to the open end of the base plate located on the cryopreservation rack body, and a handle is hinged to the front of the front baffle for pulling the base plate along the body of the cryopreservation rack.

[0011] A rear baffle is fixedly connected to one end of the front baffle of the base plate;

[0012] The label slot is fixedly connected to one end of the front baffle located on the handle.

[0013] Furthermore, the upper end of the base plate is fixedly connected with partitions at equal intervals for limiting the position of adjacent cryopreservation boxes;

[0014] The bottom plate has baffles on both sides for limiting the position of the cryopreservation box in conjunction with the partition. The baffles and the partition are arranged in an "I" shape.

[0015] Furthermore, the base plate has equally spaced arc-shaped notches on both sides for removing the cryopreservation boxes on the base plate;

[0016] The arc-shaped notch corresponds one-to-one with the serial number identifier.

[0017] Furthermore, two sets of the brackets are arranged in parallel and fixedly connected to the lower end of the base plate;

[0018] The support is V-shaped to reduce the contact area between it and the cryopreservation rack body.

[0019] Furthermore, the cryopreservation rack body has guide plates spaced at equal intervals from top to bottom inside;

[0020] The guide plate is in contact with the lower end line of the bracket.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model reduces the freezing area of ​​the base plate by using a transition between the bottom of the base plate and the support and the cryopreservation rack body. When it is necessary to remove the cryopreservation box from the cryopreservation rack body, first determine the layer number of the cryopreservation box by checking the number in the label slot, and then pull the base plate of that layer out of the cryopreservation rack. Then, check the serial number to locate the specific position of the cryopreservation box to be removed. This achieves a small freezing area of ​​the base plate, convenient pulling, and high sample positioning efficiency. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A cryogenic rack with anti-freeze guide rails and an identification structure includes a cryogenic rack body 12, and further includes:

[0031] The storage component includes a base plate 3 that is slidably disposed within the cryopreservation rack body 12 for supporting and limiting the cryopreservation box 10, and a bracket 4 disposed at the lower end of the base plate 3 for reducing the contact area between the base plate 3 and the cryopreservation rack body 12.

[0032] The identification structure includes serial number markers 7 located on both sides of the base plate 3 for identifying individual cryopreservation boxes 10, and label slots 6 located at the opening of the cryopreservation box 10 on the base plate 3 for classifying and marking each layer of the base plate 3.

[0033] It should be noted that by transitioning the bottom of the base plate 3 to the support 4 and the cryopreservation rack body 12, the freezing area of ​​the base plate 3 is reduced. When the cryopreservation box 10 needs to be removed from the cryopreservation rack body 12, the number of layers of the cryopreservation box 10 is first determined by checking the number in the label slot 6. Then, after the base plate 3 of that layer is pulled out from the cryopreservation rack 10, the specific position of the cryopreservation box 10 to be removed is locked by checking the serial number 7. This achieves the effect of small freezing area of ​​the base plate 3, convenient pulling, and high sample positioning efficiency.

[0034] As an improvement, the base plate 3 is fixedly connected to the open end of the cryopreservation rack body 12 with a front baffle 1, and the front part of the front baffle 1 is hinged with a handle 5 for pulling the base plate 3 along the inside of the cryopreservation rack body 12.

[0035] A rear baffle 2 is fixedly connected to one end of the front baffle 1 of the base plate 3;

[0036] The label slot 6 is fixedly connected to one end of the front baffle 1 located on the handle 5.

[0037] Furthermore, the upper end of the base plate 3 is fixedly connected with partitions 9 at equal intervals for limiting the position of adjacent cryopreservation boxes 10;

[0038] The base plate 3 has baffles on both sides for limiting the position of the cryopreservation box 10 in conjunction with the partition 9. The baffles and the partition 9 are arranged in an "I" shape.

[0039] Furthermore, the base plate 3 has equally spaced arc-shaped notches 8 on both sides for removing the cryopreservation box 10 on the base plate 3;

[0040] The arc-shaped notch 8 corresponds one-to-one with the serial number identifier 7.

[0041] Among them, two sets of brackets 4 are arranged in parallel and are fixedly connected to the lower end of the base plate 3;

[0042] The support 4 is V-shaped to reduce the contact area between it and the cryopreservation rack body 12.

[0043] In addition, guide plates 11 are provided at equal intervals from top to bottom inside the cryopreservation rack body 12;

[0044] The guide plate 11 is in contact with the lower end line of the bracket 4;

[0045] It should be added that a gap is formed between the guide plate 11 and the base plate 3 under the support of the bracket 4, and the base plate 3 has a hole in the middle that corresponds one-to-one with the cryopreservation box 10 for the circulation of cold air on the outside of the cryopreservation box.

[0046] It should be noted that in the specific implementation of this utility model, by fixing a “V” shaped bracket 4 to the lower end of the base plate 3, the base plate 3 and the guide plate 11 are in line contact under the transition effect of the bracket 4, which greatly reduces the contact area between the base plate 3 and the guide plate 11, and avoids large-area freezing of the bottom surface of the base plate 3 and the guide plate 11, making it difficult to pull the base plate 3 out.

[0047] When determining the sample to be retrieved, first check the number of layers corresponding to the sample in the label slot 6. Then, pull the handle 5 corresponding to that layer. The handle 5, through the front baffle 1, drives the base plate 3 to slide along the guide plate 11 under the transition of the bracket 4, so that the base plate 3 brings the cryopreservation box 10 out of the cryopreservation rack body 12. Then, by checking the serial number 7, locate the specific position of the sample to be retrieved on the base plate 3, and retrieve the corresponding cryopreservation box 10 at the corresponding serial number 7. This achieves the effect of quickly finding and retrieving the sample, with high sample positioning efficiency.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
