[0002] Ultra-low temperature biological storage equipment needs to store biological specimens including human organs and tissues, whole blood, plasma, serum, biological fluids or processed biological samples under ultra-low temperature conditions, and has stringent requirements on the conditions of the low-temperature insulated storage tank. Therefore, it is required that a low-temperature insulated storage tank of an ultra-low temperature biological storage equipment store as many biological specimens as possible in order to save storage costs. At the same time, it is required that the storage unit and the low-temperature insulated storage tank have good sealing performance to increase the reliability of the low-temperature insulated storage tank in storing biological samples. However, the currently used low-temperature insulated storage tanks basically adopt a rotating cage structure. For example, the patent application number is 202410246517.2, and the patent name is a patent application for a biological sample storage container for an ultra-low temperature biological storage device. The internal rotating cage structure and the biological sample storage container adopt a rotating access method to place or access biological samples. During the operation of the rotating cage structure of the biological sample storage container, if there is vibration, the rotating cage structure and the biological sample storage container are easily misaligned, resulting in poor sealing.

[0014] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of the present invention, but the description is for the purpose of illustrating the general principles of the present invention, and is not intended to limit the scope of the present invention. The scope of protection of the present invention shall be determined as defined by the attached claims.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings, but the accompanying drawings are not intended to limit the present invention.

[0016] Example

[0017] like Figure 1-2As shown, a low-temperature insulated storage tank for ultra-low-temperature biological storage equipment includes a low-temperature insulated storage tank body 2, which is provided with a plurality of storage units 2a, a storage tank body 2b and a cover body 2c; the cover body 2c is arranged at the upper end of the storage tank body 2b and forms a storage space 2b1, the storage space 2b1 is used to be filled with refrigerated liquid nitrogen to keep the storage space 2b1 at a low temperature of -196°C, and the cover body 2c is provided with a plurality of storage placement ports 2c1. The cross-section of the storage placement ports 2c1 is an inverted trapezoidal shape with a larger upper portion and a smaller lower portion. The storage units 2a are arranged in the storage placement ports 2c1, and the storage units 2a and the storage placement ports 2c1 are tightly matched.

[0018] like Figure 2 and Figure 3 As shown, since the cross-section of the storage placement port 2c1 is an inverted trapezoidal shape, the upper end matching portion 2a5 of the storage unit 2a and the storage placement port 2c1 adopt a conical surface matching method. Under the action of gravity, the storage unit 2a matches the storage placement port 2c1 more tightly, and more effectively ensures the sealing of the storage unit 2a and the storage placement port 2c1. The structure is simple and the practicality is good.

[0019] Preferably, the entrance of the storage opening 2c1 is square-shaped. The storage opening 2c1 is square-shaped, and the upper portion of the storage unit 2a that matches it is also square-shaped, which is convenient for determining the direction when taking out or placing, and is easy to locate, thereby improving the convenience of storage and access.

[0020] More preferably, the included angle 2c2 between the inclined side of the storage opening 2c1 and the axis is between 1° and 2°.

[0021] More preferably, Figure 3 As shown, the storage unit 2a is provided with a gripping opening 2a1, a positioning fixing hole 2a2 is provided at the center of the gripping opening 2a1, and several layers of sub-storage units 2a3 are provided at the lower end of the storage unit 2a, and the sub-storage units 2a3 are used to store biological storage boxes 2a4.

[0022] like Figure 4 The figure shows the relationship between the storage unit and the grasping mechanism. During the grasping operation of storage unit 2a, the driving electromagnet 1b of the grasping mechanism, mounted on the mounting bracket 1a, drives the central positioning shaft 1d to move and extend into the positioning and fixing hole 2a2, thereby positioning and fixing storage unit 2a. Simultaneously, the driving electromagnet 1b drives several grasping claws 1c to expand outward and grasp the grasping opening 2a1, thereby completing the grasping of storage unit 2a. During this process, the central positioning shaft 1d positions and fixes storage unit 2a, while the grasping claws 1c grasp the storage unit 2a. This prevents the storage unit 2a from shaking during the grasping process, ensuring stable grasping and transfer of storage unit 2a.

[0023] More preferably, the storage tank body 2b is a double-layer insulation structure, and a vacuum insulation cavity is formed between the double-layer insulation structures. The use of the double-layer insulation structure is conducive to maintaining the storage space 2b1 of the low-temperature insulated storage tank at a low temperature of -196°C for a long time.

[0024] The present invention relates to a low-temperature thermal insulation storage tank for ultra-low-temperature biological storage equipment, comprising a low-temperature thermal insulation storage tank body, wherein the low-temperature thermal insulation storage tank body is provided with a plurality of storage units, a storage tank body, and a cover body; the cover body is provided at the upper end of the storage tank body and forms a storage space, the cover body is provided with a plurality of storage placement openings, the storage units are provided in the storage placement openings, and the cross-section of the storage placement openings is an inverted trapezoidal shape with a larger upper portion and a smaller lower portion, and the storage units are tightly fitted with the storage placement openings. Since the cross-section of the storage placement openings is an inverted trapezoidal shape, the storage units and the storage placement openings adopt a conical surface fitting method, and the storage units are more tightly fitted with the storage placement openings under the action of gravity, more effectively ensuring the sealing of the storage units and the storage placement openings, and the structure is simple and the practicality is good.

However, as previously mentioned, it should be understood that the present invention is not limited to the form disclosed herein and should not be construed as excluding other embodiments. Rather, the present invention can be used in various other combinations, modifications, and environments and can be modified within the scope of the present invention as taught herein or through the techniques or knowledge of the relevant art.
