[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments. Example 1:

[0027] like Figures 1 to 4As shown, a laboratory reagent storage device according to one embodiment of this utility model includes a cabinet 1. A protective shell 11 is fixed to the cabinet 1 by welding or snap-fit ​​connection. A temperature control mechanism 12 is installed inside the protective shell 11. A gas supply pipe 121 for supplying temperature-regulating gas into the cabinet 1 is connected to the temperature control mechanism 12 by clamps or flanges. A control panel 13 electrically connected to the temperature control mechanism 12 is installed at the cabinet door of the cabinet 1. The control panel 13 can send temperature adjustment commands to the temperature control mechanism 12, thereby achieving precise temperature control of the storage space inside the cabinet 1. The above-mentioned temperature control principle is similar to the temperature control logic of existing storage equipment such as refrigerators and freezers, and is a well-known technology in the field, so it will not be described in detail here.

[0028] like Figures 4 to 6 As shown, multiple pairs of fixing tubes 3 are installed on the rear panel of the cabinet 1, and a placement plate 2 is slidably connected to the fixing tubes 3. When cleaning and disinfecting the inside of the cabinet, the placement plate 2 can be directly removed from the cabinet 1, effectively preventing mold or bacteria growth at the connection between the placement plate 2 and the cabinet 1 due to cleaning dead corners, thus improving the convenience of cleaning and the hygiene and safety of the device.

[0029] Specifically, each pair of fixed tubes 3 is coplanar and horizontally arranged, parallel to the ground. The placement plate 2 has a second through hole 202 that matches the fixed tube 3. The placement plate 2 is fitted and slidably connected to the pair of fixed tubes 3 through the second through hole 202. When cleaning the cabinet 1, the placement plate 2 can be quickly removed from the cabinet 1 by sliding it outwards after opening the cabinet door. This facilitates thorough cleaning of the placement plate 2 itself and provides unobstructed space for cleaning and disinfection operations inside the cabinet 1, improving the thoroughness of the cleaning.

[0030] To ensure the stable fixation of the placement plate 2 and guarantee the safety of reagent storage, the laboratory reagent storage device is also equipped with a locking assembly. The locking assembly includes a stud 32 and a nut 4. The stud 32 is welded to the end of the fixing tube 3 away from the rear panel of the cabinet 1, and the nut 4 is threadedly connected to the stud 32. By tightening the nut 4, the placement plate 2 on the fixing tube 3 is axially locked, effectively preventing accidental sliding of the placement plate 2 along the fixing tube 3 during use. For cleaning, simply unscrew the nut 4 from the stud 32 to release the lock and remove the placement plate 2; the operation is convenient and efficient.

[0031] Furthermore, the diameter of the stud 32 is set to be smaller than the diameter of the fixing tube 3, forming a stepped transition structure. This can prevent the stud 32 from interfering with the sliding of the placement plate 2, ensuring that the placement plate 2 slides smoothly on the fixing tube 3 and improving the user experience.

[0032] Furthermore, one end of the fixing pipe 3 penetrates the rear panel of the cabinet 1 and is connected to the air supply pipe 121. Multiple fourth through holes 301 are provided on the pipe wall of the fixing pipe 3. The placement plate 2 is provided with an air equalization chamber 21, and multiple first through holes 201 connected to the air equalization chamber 21 are provided on the plate surface of the placement plate 2.

[0033] Specifically, the temperature-regulating gas output by the temperature control mechanism 12 is sequentially transported to the fixed pipe 3 via the gas delivery pipe 121, and then enters the gas equalization chamber 21 of the placement plate 2 through the fourth through hole 301 on the fixed pipe 3. After the temperature-regulating gas is evenly distributed in the gas equalization chamber 21, it flows out synchronously from multiple first through holes 201 to form a multi-directional uniform air supply structure, which balances the temperature differences in various areas inside the cabinet 1, effectively avoids local temperature fluctuations, significantly improves the uniformity and accuracy of temperature control inside the cabinet 1, and provides a stable temperature field environment for reagent storage.

[0034] like Figure 5 and Figure 6 As shown, the gas equalization chamber 21 has an integrally formed guide portion adapted to the fixed tube 3. This guide portion consists of a pair of guide plates 22, which are symmetrically arranged on both sides of the second through hole 202. The guide plates 22 can provide precise guidance for the fixed tube 3, ensuring that the fixed tube 3 smoothly passes through the placement plate 2. At the same time, they can significantly enhance the overall structural strength of the placement plate 2, preventing it from deforming when sliding or carrying reagents. The guide plates 22 have multiple third through holes 221. The temperature-regulating gas flowing out of the fourth through hole 301 of the fixed tube 3 can flow into the gas equalization chamber 21 through the third through holes 221, ensuring a smooth gas transmission path.

[0035] Preferably, the diameter of the third through hole 221 is larger than the diameter of the fourth through hole 301, thereby reducing the resistance to gas flow.

[0036] Compared with existing technologies, this method not only allows the placement plate 2 to be directly removed from the cabinet 1, effectively preventing mold or bacteria growth at the connection between the placement plate 2 and the cabinet 1 due to cleaning dead spots, thus improving the ease of cleaning and hygiene safety of the device, but also balances the temperature differences between different areas inside the cabinet 1, effectively avoiding local temperature fluctuations and significantly improving the uniformity and accuracy of temperature control inside the cabinet 1, providing a stable temperature environment for reagent storage. Example 2:

[0037] like Figure 4 , Figure 6 and Figure 7As shown, the outer circumferential surface of the fixed tube 3 away from the stud 32 is machined with an external thread 31. A threaded hole 101 adapted to the external thread 31 is opened at the corresponding position on the rear panel of the cabinet 1. The fixed tube 3 is detachably connected to the rear panel of the cabinet 1 through the threaded engagement of the external thread 31 and the threaded hole 101. When it is necessary to clean and disinfect the inside of the cabinet 1, the fixed tube 3 can be unscrewed from the threaded hole 101 and removed to thoroughly eliminate the cleaning dead corners occupied by the fixed tube 3, further improving the thoroughness and ease of operation of cleaning and disinfection inside the cabinet 1.

[0038] Furthermore, a connecting assembly is provided between the fixed pipe 3 and the gas transmission pipe 121. This connecting assembly includes a pagoda connector 51 and a connecting pipe 52. One end of the connecting pipe 52 is welded and fixed to the pagoda connector 51, and the other end is welded and connected to the gas transmission pipe 121 to form an integrated gas transmission channel. After the fixed pipe 3 is screwed into the threaded hole 101 on the rear panel of the cabinet 1 and tightened, its end near the rear panel of the cabinet 1 will be precisely inserted into the interface of the pagoda connector 51, realizing the rapid connection between the fixed pipe 3 and the gas transmission pipe 121.

[0039] To enhance the installation stability of the pagoda connector 51, the connection assembly also includes a fixing bracket 5. The fixing bracket 5 is welded and fixed to the rear end face of the cabinet 1, and the pagoda connector 51 is connected and fixed to the fixing bracket 5 by welding, forming a double fixing structure, which significantly improves the load-bearing strength and installation reliability of the pagoda connector 51. At the same time, a rubber sealing ring (not shown in the figure) is embedded in the inner wall of the interface of the pagoda connector 51. When the fixing tube 3 is inserted into the pagoda connector 51, the rubber sealing ring will tightly fit the inner wall of the fixing tube 3, effectively enhancing the sealing performance of the connection, preventing the leakage of temperature-regulating gas, and ensuring gas transmission efficiency.

[0040] In addition, an elastic pad 33 is glued to one end face of the fixing tube 3 near the rear panel of the cabinet 1, and a groove 23 adapted to the elastic pad 33 is opened on the placement plate 2 at the position corresponding to the elastic pad 33. During assembly, the fixing tube 3 is rotated to screw it into the threaded hole 101. When the elastic pad 33 is tightly attached to the rear panel of the cabinet 1, the elasticity of the elastic pad 33 can be used to finely adjust the fixing tube 3 so that the fourth through hole 301 is kept horizontal so as to align with the third through hole 221 on the guide plate 22. This ensures that the temperature-regulating gas can flow smoothly from the fourth through hole 301 into the third through hole 221, avoiding the impact of misalignment on gas flow efficiency.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
