Description

Technical Field

[0001] This invention belongs to the technical field of sample storage equipment, and more specifically, it relates to a food inspection sample storage device with classification function. Background Technology

[0002] This food testing sample storage device with categorization capabilities is an advanced storage unit specifically designed for the food testing field. Its scientifically designed, structured structure not only allows for the precise categorization and storage of various food testing samples, effectively preventing cross-contamination and confusion, but also enables efficient sample management, significantly improving testing efficiency. Furthermore, the device fully considers the stringent requirements of food testing for sample preservation environments, possessing precise temperature and humidity control capabilities, as well as excellent sealing, moisture-proof, and insect-proof properties, comprehensively ensuring sample quality and providing solid support for the accuracy and reliability of food testing.

[0003] In current food inspection work, large-capacity cabinets are often chosen as sample storage devices to meet the need for storing large quantities of samples. To increase capacity, these cabinets are typically designed with considerable depth. However, when a large number of samples are stored inside the cabinet, the drawbacks of this increased depth become apparent, as samples at the back are difficult to access. Furthermore, when storing liquid samples, prolonged standing may lead to precipitation and crystallization, which can affect subsequent testing. Summary of the Invention

[0004] In view of the problems in related technologies, the present invention proposes a food inspection sample storage device with classification function to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a food inspection sample storage device with classification function, the main structure of which is a storage cabinet. Inside the storage cabinet, four drive wheels are rotatably mounted via bearings, arranged in pairs. Both pairs of drive wheels are connected by drive belts, with the two drive wheels in the same pair fixedly connected by a connecting shaft to ensure synchronous rotation. A storage box is rotatably mounted between the two drive belts via a rotating shaft. Several sample boxes are evenly slidably connected inside the storage box, and each sample box contains sample tubes. A first hook is fixedly mounted at the bottom of each sample box, engaging with a locking mechanism located inside the storage box to ensure stable fixation of the sample box. A connecting member is fixedly mounted at the top of the storage cabinet, and a rod is rotatably mounted on the connecting member via a rotating shaft. The rod abuts against the storage box to provide support and guidance. A damper is installed between the storage box and the two drive belts to reduce vibration and impact, and a damper is also installed between the connecting member and the rod to further improve stability. One of the drive wheels is fixedly mounted with the output end of a drive motor to drive the entire transmission system.

[0006] Furthermore, a placement slot is fixedly installed inside the sample box. One end of a return spring is fixedly installed on the inner wall of the placement slot, and an arc-shaped clamping plate is fixedly installed on the other end of the return spring. The arc-shaped clamping plate is made of rubber and has good elasticity and anti-slip properties. Two return springs and two arc-shaped clamping plates are provided, and the two arc-shaped clamping plates are arranged opposite each other to secure the sample tube tightly and prevent it from shaking or being damaged during transportation or storage.

[0007] Furthermore, the locking mechanism includes a fixing plate fixedly installed on the inner wall of the storage box. The fixing plate has a first sliding groove, which provides sliding space. A sliding block is slidably connected to the first sliding groove, and the sliding block can slide freely within the first sliding groove. The sliding block has an irregular sliding groove, which guides the movement trajectory of other components.

[0008] Furthermore, the irregular groove is provided with a recess, and one end of a rotating rod is slidably connected to the irregular groove. The rotating rod can slide within and is guided by the irregular groove. The other end of the rotating rod is rotatably mounted on a fixed plate via a rotating shaft to achieve rotation of the rotating rod. A guide rod is fixedly installed on the sliding block. The guide rod passes through the fixed plate and fits against the storage box to provide additional support and guidance, ensuring stable sliding of the sliding block.

[0009] Furthermore, one end of a compression spring is fixedly installed inside the first sliding groove, and the other end of the compression spring is fixedly installed on the sliding block to provide elastic force so that the sliding block can be reset when no external force is applied. The end of the rotating rod near the irregular sliding groove engages with the groove to form a locking state. When the rotating rod slides to the groove, a stable locking state can be formed, thereby fixing the position of the sliding block.

[0010] Furthermore, a second sliding groove is provided at the bottom of the sliding block, and a connecting rod is fixedly installed at the bottom of the fixing plate. Two connecting rods are provided, and one end of a second hook is rotatably mounted on each connecting rod via a rotating shaft. The second hook can rotate on the connecting rod. The other end of the second hook engages with the first hook to secure the sample box. A limiting rod is fixedly installed on the second hook. The limiting rod is slidably connected inside the second sliding groove and abuts against the two connecting rods to limit the rotation range of the second hook, ensuring accurate engagement with the first hook.

[0011] Furthermore, the storage box is fixedly equipped with a nameplate, which is used to indicate the category or number of the sample box for easy management and retrieval. The storage box has good sealing properties to prevent external air or moisture from entering and affecting the quality of the samples. The drive motor is fixedly mounted on the storage cabinet to ensure stable operation.

[0012] Furthermore, a storage box is fixedly installed inside the storage cabinet for holding desiccant to absorb moisture and maintain a dry environment. The storage cabinet has a hinged door for easy opening and closing. The storage cabinet is fixedly mounted on a movable platform, and casters are fixedly installed at the bottom of the platform. These casters are self-locking, allowing for easy movement of the storage cabinet and its positioning when needed.

[0013] Compared with the prior art, the present invention has the following advantages: 1. During operation, the drive motor rotates the transmission wheel and belt, causing the storage box to rotate slightly due to the resistance of the rods. This rotation agitates the liquid samples in the test tubes within the storage box, effectively preventing crystallization that can occur if the samples remain static for extended periods. Sample crystallization can alter the physical and chemical properties of the sample, affecting the accuracy and reliability of subsequent food testing results. This equipment design fundamentally solves this problem, providing more accurate and stable sample conditions for food testing.

[0014] 2. The sample box achieves precise and stable engagement through a first hook and a locking mechanism. The various components of the locking mechanism work together, such as the sliding block moving under the action of a compression spring, the engagement of the rotating rod with the irregular sliding groove, and the accurate alignment of the second hook with the first hook. This ensures the sample box is reliably fixed within the storage box, effectively preventing it from shaking or accidentally slipping out. Simultaneously, the return spring and arc-shaped clamping plate inside the sample box automatically adjust the clamping force according to the size of the sample tubes, tightly securing them and preventing damage during transportation or storage due to equipment shaking or other factors, providing multiple layers of protection for the samples.

[0015] 3. The drive motor drives the transmission belt, allowing the storage boxes to move and rotate flexibly within the storage cabinet. Storage boxes originally located on the upper or inner sides can be easily rotated to an easily accessible position, eliminating the need for operators to reach them forcefully. This significantly saves time and effort in retrieving and storing samples, improving work efficiency. Furthermore, nameplates welded to the storage boxes indicate the type or number of the sample box, facilitating quick sample retrieval and management. Self-locking casters installed at the bottom of the storage cabinet facilitate the movement and securing of the equipment, further enhancing its ease of use and flexibility.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0022] Please see Figures 1-9As shown, this invention is a food testing sample storage device with classification function, including a storage cabinet 1. Inside the storage cabinet 1, four transmission wheels 2 are rotatably mounted via bearings, arranged in pairs. Both groups of transmission wheels 2 are connected by transmission belts 3. Two transmission wheels 2 in the same group are fixedly connected by a connecting shaft 4 to ensure synchronous rotation. A storage box 5 is rotatably mounted between the two transmission belts 3 via a rotating shaft. Several sample boxes 6 are evenly slidably connected inside the storage box 5, and the interior of each sample box 6 is used to hold sample tubes. A first hook 7 is fixedly mounted at the bottom of each sample box 6, which engages with a locking mechanism located inside the storage box 5 to ensure stable fixation of the sample box 6. A connecting member 8 is fixedly mounted at the top of the storage cabinet 1. A rod 9 is rotatably mounted on the connecting member 8 via a rotating shaft. The rod 9 abuts against the storage box 5 to provide support and guidance. A damper is installed between the storage box 5 and the two transmission belts 3 to reduce vibration and impact. A damper is also installed between the connector 8 and the rod 9 to further improve stability. One of the transmission wheels 2 is fixedly mounted with the output end of the drive motor 10 to drive the entire transmission system.

[0023] The working principle of the food inspection sample storage device with classification function proposed in this invention is as follows: During operation, the drive motor 10 is started, and the output end of the drive motor 10 drives one of the transmission wheels 2 fixedly connected to it to rotate. Since the two transmission wheels 2 in the same group are fixedly connected by the connecting shaft 4, the two transmission wheels 2 in this group will rotate synchronously. And since both groups of transmission wheels 2 are connected by transmission belts 3, the two groups of transmission wheels 2 will jointly drive the two transmission belts 3 to rotate.

[0024] During operation, the two drive belts 3 move the storage box 5 within the storage cabinet 1 via a rotating shaft. As the storage box 5 moves, the connecting member 8, fixedly installed at the top of the storage cabinet 1, has a rotating rod 9 that contacts the storage box 5. When the storage box 5 passes the rod 9, it rotates slightly due to this contact. This rotation causes the liquid sample in the test tubes inside the storage box 5 to slosh, effectively preventing crystallization from occurring due to prolonged static storage.

[0025] Meanwhile, dampers are installed between the two drive belts 3 and the storage box 5. During the rotation of the storage box 5 due to the contact of the rod 9 and during the overall movement, the dampers reduce vibration and impact, ensuring the smooth operation of the storage box 5. A damper is also installed between the connecting piece 8 and the rod 9, further improving the stability of the entire equipment during operation.

[0026] When the storage box 5 moves under the drive of the transmission belt 3, through the overall design structure, the storage box 5 originally located on the upper layer can rotate to the lower layer position, and the storage box 5 originally on the inner side can rotate to the outer side position. In this way, when it is necessary to retrieve a sample, the operator does not need to exert effort to reach the upper or inner storage box 5. They only need to wait for the target storage box 5 to rotate to a convenient position, and then easily open the storage box 5, take out the internally sliding sample box 6, and then take out the sample tubes for subsequent food testing. When it is necessary to put in a sample tube, the same reverse operation is followed. The sample box 6 is placed into the storage box 5, and the first hook 7 fixedly installed at the bottom of the sample box 6 will engage with the locking mechanism set inside the storage box 5, so as to achieve stable fixation of the sample box 6 inside the storage box 5.

[0027] In one embodiment, for the sample box 6 described above, a placement groove 11 is fixedly installed inside the sample box 6. One end of a return spring 12 is fixedly installed on the inner wall of the placement groove 11 by welding, and the other end of the return spring 12 is fixedly installed with an arc-shaped clamping plate 13 by welding. The arc-shaped clamping plate 13 is made of rubber and has good elasticity and anti-slip properties. Two return springs 12 and two arc-shaped clamping plates 13 are provided, and the two arc-shaped clamping plates 13 are arranged opposite each other to tightly fix the sample tubes and prevent them from shaking or being damaged during transportation or storage.

[0028] The working principle of the food testing sample storage device with classification function proposed in this invention is as follows: When sample tubes need to be placed into the sample box 6, the sample tubes are placed in the placement groove 11 fixedly installed inside the sample box 6. At this time, a return spring 12 is fixedly installed on the inner wall of the placement groove 11 by welding. One end of the return spring 12 is fixed to the inner wall of the placement groove 11, and the other end is connected to an arc-shaped clamping plate 13, which will be squeezed by the sample tube. Since the arc-shaped clamping plate 13 is made of rubber and has good elasticity, under the pressure of the sample tube, the two oppositely arranged arc-shaped clamping plates 13 will move to both sides respectively, while simultaneously stretching the return spring 12.

[0029] As the sample tube is placed deeper into the placement slot 11, the elastic force of the return spring 12 gradually increases. When the sample tube is in place, the return spring 12, under its own elastic force, will pull the two arc-shaped clamping plates 13 closer to the center, tightly adhering to the outer wall of the sample tube. Utilizing the anti-slip properties of the rubber material, the sample tube is tightly fixed, preventing it from shaking or being damaged during transportation or storage due to factors such as equipment vibration.

[0030] When it is necessary to remove the sample tube, simply pull the sample tube outward with a little force. The sample tube will overcome the clamping force of the arc-shaped clamping plate 13 and the elastic force of the return spring 12, causing the two arc-shaped clamping plates 13 to move to both sides again. The return spring 12 is further stretched until the sample tube is removed from the placement slot 11. After the sample tube is removed, the return spring 12 returns to its original state, driving the arc-shaped clamping plates 13 back to their initial position, waiting for the next sample tube to be placed.

[0031] In one embodiment, the aforementioned locking mechanism includes a fixing plate 14 bolted to the inner wall of the storage box 5. The fixing plate 14 has a first sliding groove 15, which provides sliding space. A sliding block 16 is slidably connected to the first sliding groove 15, and the sliding block 16 can slide freely within the first sliding groove 15. The sliding block 16 has an irregular groove 17, which guides the movement trajectory of other components.

[0032] In one embodiment, the irregular groove 17 is provided with a groove 31, and one end of a rotating rod 18 is slidably connected to the irregular groove 17. The rotating rod 18 can slide within and be guided by the irregular groove 17. The other end of the rotating rod 18 is rotatably mounted on the fixed plate 14 via a rotating shaft to achieve rotation of the rotating rod 18. A guide rod 19 is fixedly mounted on the sliding block 16 by welding. The guide rod 19 passes through the fixed plate 14 and fits against the storage box 5 to provide additional support and guidance, ensuring stable sliding of the sliding block 16.

[0033] In one embodiment, for the first sliding groove 15, one end of a compression spring 20 is fixedly installed inside the first sliding groove 15 by welding, and the other end of the compression spring 20 is fixedly installed on the sliding block 16 by welding to provide elastic force so that the sliding block 16 can be reset when no external force is applied. The end of the rotating rod 18 near the irregular sliding groove 17 is engaged with the groove 31 to form a locking state. When the rotating rod 18 slides to the groove 31, a stable locking state can be formed, thereby fixing the position of the sliding block 16.

[0034] In one embodiment, the sliding block 16 has a second sliding groove 21 at its bottom. A connecting rod 22 is welded to the bottom of the fixing plate 14. Two connecting rods 22 are provided, and one end of a second hook 23 is rotatably mounted on each rod via a rotating shaft. The second hook 23 can rotate on the connecting rod 22. The other end of the second hook 23 engages with the first hook 7 to fix the sample box 6. A limiting rod 24 is welded to the second hook 23. The limiting rod 24 is slidably connected inside the second sliding groove 21 and abuts against the two connecting rods 22 to limit the rotation range of the second hook 23, ensuring accurate engagement with the first hook 7.

[0035] In one embodiment, the storage box 5 is fixedly mounted with a nameplate 25 by welding. The nameplate 25 is used to indicate the category or number of the sample box 6, facilitating management and retrieval. The storage box 5 has good sealing properties to prevent external air or moisture from entering and affecting the quality of the samples. The drive motor 10 is fixedly mounted on the storage cabinet 1 by bolts to ensure stable operation.

[0036] In one embodiment, for the storage cabinet 1 described above, a storage box 26 is bolted to the inside of the storage cabinet 1. The storage box 26 is used to place a desiccant to absorb moisture inside the cabinet and maintain a dry environment. The storage cabinet 1 is hinged to have a cabinet door 27 for easy opening and closing. The storage cabinet 1 is bolted to a movable plate 28, and casters 29 are bolted to the bottom of the movable plate 28. The casters 29 are self-locking, allowing the storage cabinet 1 to be moved easily and its position fixed when needed.

[0037] The working principle of the food inspection sample storage device with classification function proposed in this invention is as follows: when it is necessary to fix the sample box 6 inside the storage box 5, the sample box 6 is first pushed towards the inside of the storage box 5. During the pushing process, the sample box 6 moves together with the first hook 7 fixedly installed at its bottom. During the movement, the first hook 7 contacts the guide rod 19. Since the guide rod 19 is welded and fixed to the sliding block 16, the first hook 7 applies a pushing force to the guide rod 19, thereby pushing the sliding block 16 to slide within the first sliding groove 15 opened on the fixed plate 14.

[0038] As the sliding block 16 slides, the compression spring 20 welded and fixed in the first sliding groove 15 is compressed, generating elastic force. At the same time, the guide rod 19 welded and fixed on the sliding block 16 slides along the fixed plate 14 and the storage box 5, providing additional support and guidance for the sliding block 16, ensuring that the sliding block 16 can move stably.

[0039] During the sliding process of the sliding block 16, one end of the rotating rod 18 slides within the irregular groove 17 opened in the sliding block 16, while the other end rotates around the rotation axis fixed on the fixed plate 14. When the rotating rod 18 slides to the groove 31 of the irregular groove 17, it engages with the groove 31, thereby fixing the sliding block 16 in the current position.

[0040] Meanwhile, the second sliding groove 21 at the bottom of the sliding block 16 drives the limiting rod 24 to move. The limiting rod 24 is welded and fixed to the second hook 23, one end of which is rotatably mounted on two connecting rods 22 welded and fixed to the bottom of the fixed plate 14 via a rotating shaft. The limiting rod 24 slides within the second sliding groove 21 and abuts against the two connecting rods 22, limiting the rotation range of the second hook 23, so that the other end of the second hook 23 accurately engages with the first hook 7, thus securing the sample box 6 firmly inside the storage box 5.

[0041] When sample box 6 needs to be retrieved, simply press it down by hand. Under the pressure, sample box 6 moves downwards, and the first hook 7 applies a downward force to the second hook 23, causing the second hook 23 to rotate around the rotating shaft connected to the connecting rod 22. The rotation of the second hook 23 causes the limiting rod 24 to slide within the second sliding groove 21, simultaneously pushing the sliding block 16 to slide within the first sliding groove 15, further compressing the compression spring 20. As the second hook 23 rotates, it gradually separates from the first hook 7. When it rotates to a certain angle, the second hook 23 completely disengages from the first hook 7, releasing the fixation on sample box 6. At this point, sample box 6 can be easily removed from storage box 5.

[0042] A nameplate 25 welded to the storage box 5 indicates the category or number of the sample box 6, facilitating management and retrieval. The storage box 5 has good sealing properties, effectively preventing external air or moisture from entering and affecting sample quality.

[0043] The drive motor 10 is bolted to the storage cabinet 1, driving the transmission wheel 2 to rotate, which in turn drives the transmission belt 3, thus moving the storage box 5. Inside the storage cabinet 1, a storage box 26, bolted to the cabinet, contains a desiccant to absorb moisture and maintain a dry environment. The cabinet door 27, hinged to the cabinet 1, allows for easy opening and closing. The storage cabinet 1 is bolted to a movable plate 28, whose bottom is bolted to casters 29 with self-locking mechanism, allowing for easy movement of the storage cabinet 1 and its positioning when needed.
