[0020] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of this application. Obviously, the described embodiment is only one embodiment of this application, not all embodiments. Based on the described embodiments of this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Unless otherwise defined, technical or scientific terms used in this application should have the same meaning as commonly understood by persons having ordinary skills in the field to which this application belongs.

[0022] This embodiment provides a biological sample freezing rack 10. Figure 1 is a perspective view of a biological sample freezing rack 10 according to some embodiments of the present application; Figure 2 is a cross-sectional view of a biological sample freezing rack 10 according to other embodiments of the present application; Figure 3 2 is a perspective view of the first spring piece 200 of the biological sample freezing rack 10 according to other embodiments of the present application.

[0023] The biological sample freezing rack 10 includes a rack body 100, which defines at least one accommodating cavity 110 for accommodating a freezing box 111. A first elastic piece 200 is riveted to the inner wall of at least one of the accommodating cavities 110, and the first elastic piece 200 is used to elastically fix the freezing box 111.

[0024] The biological sample freezing rack 10 can be designed as a multi-layer structure, and each layer can be distributed with grids for placing freezing boxes 111. The biological sample freezing rack 10 is convenient for managing and accessing samples, and can also maximize the use of storage space. The biological sample freezing rack 10 can be made of low-temperature resistant materials such as stainless steel, and can withstand extremely low temperatures without deformation or damage. The biological sample freezing rack 10 has a strong and stable structure, which can ensure the stability of the sample during storage. The multi-layer design makes the access and management of samples more convenient.

[0025] Cryoboxes 111 are containers specifically designed for storing and freezing biological specimens. They are widely used in laboratories, hospitals, and research institutions, playing a particularly important role in the long-term preservation of biological specimens, cells, and blood products. Cryoboxes 111 are typically made of cryogenically and corrosion-resistant materials to ensure structural integrity and stability even at extremely low temperatures. Common materials include polycarbonate (PC), polypropylene (PP), and waterproof fiberboard. These materials not only possess excellent mechanical properties but also maintain chemical stability in ultra-low temperature environments, thereby protecting stored items from damage.

[0026] Among them, the first spring piece 200 can be riveted to various positions of the inner wall of the accommodating chamber 110, so that the freezing box 111 can be limited at various positions. Riveting is a technology that uses rivets to connect two or more metal parts together. The basic principle is to use rivets to easily install two or more metal parts together, and form a diffuse "mushroom head" at the end of the riveting rod to form a strong connection. Since riveting itself is well known to those skilled in the art, it will not be described here. Specifically, the first spring piece 200 and the frame body 100 are both provided with rivet holes, and the biological sample freezing rack 10 also includes rivets arranged in the rivet holes.

[0027] The first spring piece 200 of the biological sample freezing rack 10 provided in this embodiment can secure the freezing box 111, preventing it from falling. Furthermore, the first spring piece 200 is riveted, resulting in less deformation than welding (welding causes significant deformation, while riveting causes less deformation) and greater stability than threaded connections (threaded connections are prone to unreliability at low temperatures, and bolts may loosen at low temperatures or during transportation, while riveting eliminates this risk).

[0028] In some embodiments, the first elastic piece 200 is riveted to one lateral side of the inner wall of the accommodating cavity 110 , thereby achieving fixation of the freezing box 111 in the lateral direction.

[0029] In some embodiments, a second spring clip 300 is riveted to the other lateral side of the inner wall of at least one of the accommodating chambers 110. This further secures the cryostat 111 in the lateral direction. Furthermore, this improves the smoothness of installing the cryostat 111 in the accommodating chamber 110, making it suitable for automated operation.

[0030] In some embodiments, the first elastic piece 200 is provided with a plurality of rivet holes arranged at intervals, and the first elastic piece 200 is riveted to the inner wall of the accommodating cavity 110 through the plurality of rivet holes, thereby improving the stability of the connection.

[0031] Specifically, the plurality of rivet holes are provided at the front end of the first spring piece 200. This facilitates installation of the first spring piece 200 and facilitates securing the cryobox 111. In some embodiments, the plurality of rivet holes can be arranged in a front-to-back direction, thereby ensuring connection stability.

[0032] In some embodiments, the first elastic clip 200 includes a first section 210, a second section 220, and a third section 230. The front end of the first section 210 is riveted to the inner wall of the accommodating chamber 110, the rear end of the first section 210 is fixedly connected to the front end of the second section 220, and the rear end of the second section 220 is connected to the front end of the third section 230. The third section 230 extends in the front-to-back direction and is used to elastically fix the cryopreservation box 111. This first elastic clip 200 has a simple and stable structure and effectively fixes the cryopreservation box 111.

[0033] In some embodiments, the second section 220 extends from front to back toward the freezing box 111 , thereby facilitating the fixing of the freezing box 111 .

[0034] In some embodiments, the front-to-back dimension of the first spring clip 200 is less than or equal to half the front-to-back dimension of the accommodating cavity 110. This not only ensures the securement of the cryopreservation box 111, but also reduces the cost of the first spring clip 200 and the overall weight of the biological sample freezing rack 10.

[0035] In some embodiments, the at least one accommodating cavity 110 includes a plurality of accommodating cavities 110 arranged at intervals, thereby increasing the storage capacity of the cryopreservation box 111 .

[0036] It can be understood that the shape, structure, installation position, size, etc. of the second elastic piece 300 can be consistent with those of the first elastic piece 200.

[0037] Regarding the embodiments of the present application, it should also be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other to obtain new embodiments.

[0038] The above are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. The protection scope of the present application shall be based on the protection scope of the claims.
