[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the technical problems of existing food sampling and storage devices that cannot limit the position of test tubes on the rack and cannot easily lift the entire rack, leading to inconvenience in cleaning the storage containers and easy contamination of the test samples, this utility model provides a food sampling and storage device that improves the stability of test tube placement, facilitates the retrieval of the entire rack, and allows staff to clean the inside of the container promptly after retrieval, preventing bacterial growth.

[0030] It should be noted that the food sampling and storage device described in this utility model is used in, but not limited to, the field of food processing technology. For ease of explanation, this utility model only uses the application of the food sampling and storage device in the field of food processing technology as an example for explanation. The principle of the food sampling and storage device applied to other types of equipment is essentially the same as that applied to the field of food processing technology, and will not be described in detail here.

[0031] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a food sampling and storage device according to an embodiment of the present invention. A food sampling and storage device includes:

[0032] Box 1, which has a cavity inside;

[0033] The inner shell 2 is fixed in the cavity and maintains a gap with the inner wall of the box 1. Both sides of the inner wall of the inner shell 2 are provided with bearing plates 21.

[0034] The test tube plate 3 has a groove 31 on its top, and a plurality of test tube holes 311 are equally spaced in the groove 31. The test tube plate 3 has two extension shells 4 integrally formed on both sides that cooperate with the support plate 21, and the test tube plate 3 is embedded in the support plate 21 through the extension shells 4.

[0035] The limiting end 5 includes a fixed post 51, a fixed plate 52, a movable plate 53, and an elastic element 54. The fixed post 51 is disposed on the upper end face of the test tube plate 3, and the fixed plate 52 is fixed on the fixed post 51. The movable plate 53 is slidably connected to the fixed post 51 and close to the fixed plate 52. The elastic element 54 is wrapped around the fixed post 51 and is used to push the movable plate 53 to move towards the fixed plate 52. A locking area is formed between the movable plate 53 and the fixed plate 52 for clamping the tube body in the test tube hole 311.

[0036] In this embodiment, by setting a limiting end 5 on the test tube plate 3, the tube body inside the test tube hole 311 can be effectively clamped, ensuring the stability and safety of the test tube during transportation and preventing damage or leakage caused by collision between test tubes. In addition, the test tube plate 3 is embedded into the carrier plate 21 through the integrally formed extension shell 4 on both sides, making the entire test tube plate 3 easy to disassemble. This not only facilitates the subsequent centralized handling of test tubes, but also makes it easier to thoroughly clean the inside of the storage container, reducing the risk of cross-contamination.

[0037] In one embodiment, please refer to Figure 1 and Figure 5 To improve the sealing performance of the cover plate 11 to the box body 1, the cover plate 11 is hinged to the box body 1 by a hinge, and a lifting handle 12 is connected to the cover plate 11. The cover plate 11 and the box body 1 are connected by a locking buckle.

[0038] In this embodiment, by using a hinged cover plate 11 and a locking buckle between the cover plate 11 and the housing 1, it is ensured that the cover plate 11 fits tightly against the opening of the housing 1, effectively preventing external air, moisture, or contaminants from entering the housing 1, thereby protecting the food samples stored inside from contamination and spoilage. The lifting handle 12 allows the operator to easily open or close the cover plate 11 without the need for additional tools, improving the convenience and efficiency of operation. Especially when samples need to be frequently accessed, the operation process is simplified. The locking buckle provides a stable closing mechanism, ensuring that the cover plate 11 will not be accidentally opened during transportation, guaranteeing the safety and integrity of the samples. At the same time, the locking buckle is easy to operate and facilitates quick opening and closing, making it suitable for different application scenarios such as laboratory or on-site testing. The working principle of the locking buckle is based on a mechanical locking mechanism, which can achieve quick and easy operation through simple operation. The locking mechanism relies on the opening and closing of the cover plate 11. When the cover plate 11 is closed, the moving parts of the locking buckle, such as hooks or clips, will manually align and engage with the corresponding parts on the housing 1, such as slots or recesses. At this time, the locking buckle uses the force provided by the spring or other elastic elements to press the moving parts onto the housing 1, forming a secure closed state. Once the locking buckle is in the closed position, its internal locking mechanism, such as pawls or pins, will prevent the moving parts from easily disengaging from the fixed points on the housing 1, ensuring that it will not be accidentally opened even during vibration or movement. When it is necessary to open the cover plate 11, an external force needs to be applied to overcome the locking mechanism inside the locking buckle. This is usually done by pressing, pulling, or rotating a specific operating element to release the locking mechanism, allowing the moving parts to disengage from the fixed points on the housing 1, thereby allowing the cover plate 11 to be lifted. In this application, a latch-type locking buckle, such as the NSL series from Nanxing brand, is used.

[0039] In one embodiment, please refer to Figure 1 - Figure 5 To improve the installation and removal efficiency of the test tube plate 3, the support plate 21 has a concave end, and an iron sheet 211 is installed inside the concave end. A magnet 41 is installed on the side of the extension shell 4 facing the iron sheet 211. A sponge pad 22 is installed at the bottom of the inner shell 2. Several placement grooves 221 that cooperate with the test tube holes 311 are opened on the sponge pad 22. Positioning cylinders 23 are installed at the four corners of the inner wall of the inner shell 2. An insertion groove is opened in any one of the positioning cylinders 23. A positioning post 32 that cooperates with the positioning cylinder 23 is installed on the test tube plate 3.

[0040] In this embodiment, by setting an iron sheet 211 in the concave end of the support plate 21 and setting a magnetic block 41 on the side of the extension shell 4 facing the iron sheet 211, the test tube plate 3 can be stably adsorbed onto the support plate 21. This not only improves the stability of the test tube plate 3 during transportation but also ensures that the test tube plate 3 is accurately positioned in the predetermined position, preventing positional displacement due to vibration or movement. A sponge pad 22 is provided at the bottom of the inner shell 2, and several placement grooves 221 that cooperate with the test tube holes 311 are opened on it. This can effectively buffer external impact forces and prevent the test tubes from colliding or breaking during transportation. In addition, the placement grooves 221 can ensure that each test tube has an independent space, further reducing the risk of friction and damage between them. Since the test tube plate 3 is embedded into the support plate 21 through the extension shell 4, The inner shell 2 is magnetically secured, allowing for easy disassembly for cleaning or replacement. This facilitates regular maintenance of the storage device, ensuring hygiene and preventing sample contamination. The positioning cylinders 23 at the four corners of the inner wall of the inner shell 2, along with their internal insertion slots, cooperate with the positioning posts 32 on the test tube plate 3, forming a precise alignment structure. This not only facilitates quick and accurate installation of the test tube plate 3 but also prevents equipment damage or sample loss due to misoperation or improper installation. Furthermore, it allows users to easily check and adjust the position of the test tube plate 3, ensuring all test tubes are in the correct position. This application effectively improves the overall reliability and practicality of the food sampling and storage device, especially in food safety testing scenarios requiring frequent handling and processing of large quantities of samples, effectively guaranteeing sample safety and integrity.

[0041] In one embodiment, please refer to Figure 6 To improve the seismic resistance of the inner shell 2, several spring dampers 24 are equidistantly arranged between the inner wall of the box 1 and the outer wall of the inner shell 2, and a flexible sponge layer is filled in the gap between the box 1 and the inner shell 2.

[0042] In this embodiment, the spring damper 24 can absorb and disperse the impact force applied from the outside, effectively buffering the impact transmitted to the sample in the inner shell 2. It is suitable for scenarios where fragile or sensitive samples need to be protected during transportation, ensuring the stability of the sample throughout the transportation process. In addition to the main buffering function provided by the spring damper 24, the flexible sponge layer further enhances the overall buffering effect. The flexible sponge layer can not only absorb minor vibrations, but also fill the gap between the box 1 and the inner shell 2, preventing collisions and friction caused by shaking, thereby providing more comprehensive protection. Through the multi-layered buffering structure, the external impact force on the sample is greatly reduced, reducing the risk of breakage, leakage or other forms of damage to the sample during handling, transportation or storage, ensuring the integrity of the sample and the accuracy of the test results.

[0043] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 4 To improve the clamping effect on the test tubes, the fixing post 51 includes a first post 511 and a second post 512, which are symmetrically arranged on the upper end of the test tube plate 3. The fixing plate 52 includes a first plate 521 and a second plate 522, which are fixed to the first post 511 and the second post 512 respectively. A semi-circular first groove 523 is provided on the opposite side of the first plate 521 and the second plate 522. Limiting pieces 52 for limiting the first plate 521 and the second plate 522 are provided on the first post 511 and the second post 512. 4. The movable plate 53 includes a first sliding plate 531 and a second sliding plate 532. The first sliding plate 531 and the second sliding plate 532 are disposed between the first plate body 521 and the second plate body 522. The upper and lower ends of the first sliding plate 531 and the second sliding plate 532 are slidably connected to the first column body 511 and the second column body 512, respectively. A second groove body 533 is opened on the side of the first sliding plate 531 and the second sliding plate 532 facing the first groove body 523. An elastic element 54 is disposed between the first sliding plate 531 and the second sliding plate 532 and on the first column body 511 and the second column body 512. The elastic element 54 is a spring strip.

[0044] In this embodiment, by symmetrically arranging the first column 511 and the second column 512 on the upper end of the test tube plate 3, the balance and stability of the entire limiting end 5 structure are ensured, which helps to evenly distribute the clamping force and avoid the test tube tilting or sliding due to uneven force. A semi-circular first groove 523 is provided on the opposite side of the first plate 521 and the second plate 522, which can better fit the shape of the test tube and provide a tighter and more uniform clamping force, preventing the test tube from shaking or falling off during transportation. The limiting piece 524 located on the first column 511 and the second column 512 is used to limit the first plate 521 and the second plate 522 to ensure that they do not move, thereby maintaining the precise size of the clamping area and ensuring that the test tube is always in the best clamping state. The upper and lower ends of the first sliding plate 531 and the second sliding plate 532 are slidably connected to the first column 511 and the second column 512, respectively, so that the movable plate 53 can be fixed on the fixed column 51. The upper sliding plate 531 and the lower sliding plate 532 are freely sliding, allowing users to quickly adjust the clamping position. The first sliding plate 531 and the second sliding plate 532 have a second groove 533 on the side facing the first groove 523, which further improves the fitting accuracy between the movable plate 53 and the fixed plate 52, ensuring seamless connection every time they close, and enhancing the overall clamping effect. A spring strip is provided between the first sliding plate 531 and the second sliding plate 532 and on the first column 511 and the second column 512. The elasticity of the spring strip pushes the movable plate 53 towards the fixed plate 52, forming a stable locking area. The spring strip can provide a continuous and adjustable clamping force, ensuring that the test tube remains stable throughout the entire service life. The spring strip is made of a material with good elasticity and fatigue resistance, such as stainless steel. Before assembly, the spring is pre-compressed to allow it to undergo a certain number of loading-unloading cycles, which helps to eliminate internal residual stress and improve the stability of subsequent use.

[0045] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below:

[0046] When it is necessary to clamp test tubes: The operator ensures all components are intact and prepares the test tubes to be stored. They confirm that the test tube holes 311 in the groove 31 at the top of the test tube plate 3 are clean and free of foreign objects. The operator pulls the first sliding plate 531 or the second sliding plate 532 with their fingers, pushing it away from the fixed plate 52, so that the first sliding plate 531 and the second sliding plate 532 move closer together and the second groove 533 moves away from the first groove 523. The test tubes to be stored are then placed one by one into the test tube holes 311 on the test tube plate 3. Handle the test tubes gently, ensuring they are inserted vertically into the test tube hole 311. Avoid tilting or colliding with other test tubes. Once placed, slowly stop applying force to the first sliding plate 531 and the second sliding plate 532. The spring bar will push the first sliding plate 531 and the second sliding plate 532 towards the first plate body 521 and the second plate body 522, eventually engaging with the first groove body 523 to form a stable locking area. This ensures the test tubes are firmly clamped. Check that each test tube is evenly clamped to ensure there is no loosening or tilting.

[0047] When it is necessary to loosen the test tube: Grasp the first sliding plate 531 or the second sliding plate 532 with your fingers and push it away from the fixed plate 52, so that the first sliding plate 531 and the second sliding plate 532 are close to each other and the second groove 533 is away from the first groove 523. Pay attention to the force control to ensure that the upper and lower ends of the first sliding plate 531 and the second sliding plate 532 slide smoothly along the first column 511 and the second column 512 respectively. After the first sliding plate 531 and the second sliding plate 532 are pulled to the appropriate position, gently lift the test tube to ensure that it is pulled out vertically from the test tube hole 311. Handle it gently to avoid collision with other test tubes or the edge of the test tube plate 3 to prevent damage to the test tube or sample. Carefully place the removed test tube in the prepared storage area to ensure that it is not affected by the external environment. It should be noted that when pulling open the movable plate 53, you should pay attention to the force control to avoid excessive force causing the spring strip to be compressed to the limit and pushing the first sliding plate 531 and the second sliding plate 532 to reset, which may cause the test tube to break or be damaged.

[0048] The installation steps for the test tube rack are as follows: Locate the support plates 21 on both sides of the inner shell 2, and confirm the position of the recessed end on the support plate 21. Note that an iron piece 211 should be installed inside the recessed end. Close to the magnet 41, align the extension shells 4 on both sides of the test tube plate 3 with the recessed end on the support plate 21, so that the side of the extension shell 4 facing the iron piece 211, i.e. the side with the magnet 41, is close to the iron piece 211. Gently push the test tube plate 3 so that its extension shell 4 is in close contact with the support plate 21. Use the magnetic force between the magnet 41 and the iron piece 211 to achieve a stable adsorption. Confirm the position of the positioning cylinders 23 at the four corners of the inner wall of the inner shell 2 and the position of the insertion slot inside them. Accurately insert the positioning post 32 at the bottom of the test tube plate 3 into the corresponding positioning cylinder 23, ensuring that the positioning post 32 is fully inserted into the insertion slot to complete the precise alignment. At the same time, the condition of the spring strip should be checked regularly to ensure that it still has sufficient elasticity and fatigue resistance. If necessary, pre-compression treatment or replacement should be performed to ensure long-term stability.

[0049] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
