Description

Technical Field

[0001] The utility model is applicable to the field of medical experimental tube racks and provides a combined freezing tube rack. Background Art

[0002] Cryotubes are tubular containers used for storing and transporting biological samples, chemical reagents, or other substances requiring refrigeration at low temperatures. By maintaining a constant low temperature, they prevent sample deterioration or loss of function due to temperature fluctuations during storage or transport. Cryotubes are commonly used in fields such as medicine, biological research, and chemical experiments to ensure the long-term stability and reliability of samples.

[0003] Cryotubes are typically stored in specialized refrigerated storage boxes or freezers, which provide a stable, low-temperature environment. During storage, they are arranged on racks or trays for easy management and access. To ensure the safety of the cryotubes, storage facilities are often designed with protective measures to minimize the impact of the external environment on their temperature.

[0004] Current cryovials are prone to collapse during freezing, storage, and transportation. Due to their weight and shape, cryovials are susceptible to tilting or collapsing during storage and transportation due to unstable supporting structures or external impacts. This collapse can not only damage or leak samples within the tubes, but also compromise storage efficiency and transportation safety. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] It should be noted that, in the description of the present invention, unless otherwise specified, "plurality" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0021] At the same time, in the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See also Figure 1-3 The purpose of the present utility model is to provide a combined freezing pipe rack, comprising a bottom plate 2 and a freezing pipe 1 detachably connected to the bottom plate 2; the freezing pipe 1 comprises a pipe body and a bottom ring 12 fixedly connected to the bottom of the freezing pipe 1.

[0024] The bottom plate 2 is fixedly connected to a limit plate 4 via support columns 3. Several fixing columns 21 are fixedly connected to the top of the bottom plate 2. These fixing columns 21 are evenly arranged on the top of the bottom plate 2. The limit plate 4 is provided with limiting holes 401 that correspond one-to-one with the fixing columns 21. Specifically, the support columns 3 secure the limit plate 4 at a certain distance above the bottom plate 2. The bottom ring 12 of the cryotube 1 can pass through the limit plate 4 and be connected to the fixing columns 21, thereby enabling the cryotube 1 to be installed on the device.

[0025] The top of the limiting plate 4 is fixedly connected to a limiting ring 41 at the corresponding position of the limiting hole 401. When the freezing pipe 1 is installed on the limiting plate 4, the freezing pipe 1 is passed through the limiting hole 401. The limiting ring 41 can increase the contact area with the freezing pipe 1, making the fixation more secure.

[0026] The bottom of the base plate 2 is provided with a bottom ring 22, which is coaxial with the retaining ring 41 in the height direction. A bottom ring 22 is provided at each of the four corners of the bottom of the base plate 2. Specifically, the inner diameter of the bottom ring 22 is equal to the outer diameter of the retaining ring 41. In other words, when the devices are stacked, the retaining ring 41 can be inserted into the inner portion of the bottom ring 22, making the stacked devices more stable and preventing collapse.

[0027] Preferably, the sum of the wall thickness of the freezing tube 1 and the cross-sectional radius of the fixing column 21 is equal to the inner radius of the limiting hole 401. This arrangement allows the freezing tube 1 to pass smoothly through the limiting hole 401, which secures the freezing tube 1. At the same time, the fixing column 21 can be inserted into the freezing tube 1 to further secure it.

[0028] Preferably, a tube cover 11 is threadedly connected to the top of the freezing tube 1 , and the outer diameter of the tube cover 11 is equal to the inner diameter of the bottom ring 22 .

[0029] Preferably, a necked portion 211 is provided at the top of the fixing column 21 . The necked portion 211 can provide a certain air pressure margin when the freezing pipe 1 is installed above the fixing column 21 , so that the installation of the freezing pipe 1 is smoother.

[0030] Preferably, the bottom ring 12 is provided with a through hole 121, which is used to maintain the atmospheric pressure balance inside and outside the bottom ring 12. When the fixing column 21 is inserted into the bottom ring 12, the gas in the bottom ring 12 can be discharged to the outside, making the installation smoother.

[0031] In summary, in actual use, multiple freezing tube racks can be stacked and combined with each other. When stacked and combined, the limiting ring 41 on the limiting plate 4 is nested inside the bottom ring 22. When it is needed, the experimenter can remove a single device and use it in conjunction with the freezing tube 1. When the device is used in conjunction with the freezing tube 1, the freezing tube 1 containing the experimental biological material can be inserted into the limiting hole 41 of the device. Continuing to insert downward can connect the bottom ring 12 at the bottom of the freezing tube 1 to the fixed column 21, thereby achieving a more secure fixing effect and preventing the freezing tube 1 from falling off and being damaged when the device tips over. At the same time, when a large amount of experimental materials need to be transported, multiple devices containing freezing tubes 1 can be stacked. At this time, the tube cover 11 on the freezing tube 1 can be connected to the bottom ring 22, so that it is firmly fixed during stacking and transportation and is not easy to collapse.

[0032] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
