[0002] With the deepening of environmental science research and the increasing awareness of ecological environment protection, environmental soil detection work is becoming more and more important. In the process of environmental soil detection, the collection, storage and transportation of samples are key links, and their quality directly affects the accuracy and reliability of the detection results.

[0003] At present, the commonly used soil sample storage device has many problems. The existing storage device is mostly simple in structure, usually only uses ordinary sealed containers, and lacks effective classification of samples. When multiple soil samples of different locations, different depths or different detection items need to be collected at the same time, sample confusion is easy to occur, which not only increases the work difficulty of the detection personnel, but also may lead to deviation of the detection results.

[0004] In addition, the existing storage device has deficiencies in protecting samples. Soil samples may be subjected to external forces such as vibration and collision during transportation, and ordinary storage containers cannot provide sufficient buffer protection for samples, which may easily damage the structure of samples and affect subsequent detection analysis. For example, in some complex environmental detection projects, the bumping of the transportation tool may cause the collision of sample containers, resulting in the change of the original state of the soil samples, so that the detection data cannot truly reflect the actual situation of the soil.

[0005] The existing sample storage device for environmental soil detection has obvious deficiencies in sample classification management and protection, and it is difficult to meet the growing demand of environmental soil detection work, so it is urgent to develop a new type of sample storage device to solve these problems.

[0014] 1. This utility model employs a combination of cylindrical sections around the top of the base plate and movable rods, along with a linkage structure consisting of a sliding groove, slider, connecting rod, and compression spring, and a buffer pad on the top of the support plate. When the storage box is subjected to vibration or impact, the sliding of the movable rods, the swinging of the connecting rods, and the elastic deformation of the compression springs disperse and buffer external forces, effectively reducing the impact force transmitted to the samples inside the storage box. Simultaneously, the placement opening of the positioning block inside the storage box allows for precise positioning of the sample rack, preventing samples from shifting randomly within the storage box, thus providing excellent protection for the soil samples.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, a sample storage device for environmental soil testing includes a base plate 1. Cylinders 2 are fixedly connected to the top of the base plate 1 around its four sides. Movable rods 3 are slidably connected inside the cylinders 2. A support plate 4 is fixedly connected to the top of the movable rods 3. Slide grooves are provided on the front and rear sides of the top of the base plate 1, and sliders 5 are slidably connected to both sides inside the slide grooves. A connecting rod 6 is hinged to the surface of the slider 5. The end of the connecting rod 6 away from the slider 5 is hinged to the support plate 4, and a compression spring 7 is fixedly connected between the two sliders 5. A buffer pad 8 is fixedly connected to the top of the support plate 4, and a storage box 9 is fixedly connected to the top of the buffer pad 8. A positioning block 10 is fixedly connected inside the storage box 9. A placement opening 13 is provided on the top of the positioning block 10. The number of placement openings 13 is several, and they are evenly distributed on the top of the positioning block 10. A placement rack 12 is provided inside the placement opening 13, and the placement rack 12 fits snugly against the storage box 9.

[0023] refer to Figure 1 The top back of the storage box 9 is hinged with a cover plate 14. Both sides of the front of the cover plate 14 are fixedly connected with limit blocks 15. The limit blocks 15 fit with the storage box 9. The surface of the limit blocks 15 is provided with an insertion port. Both sides of the front of the storage box 9 are provided with sliding grooves, and a locking frame 16 is slidably connected inside the sliding grooves. The locking frame 16 is inserted into the insertion port. Both sides of the front of the storage box 9 are fixedly connected with fixing blocks 17. A spring 18 is fixedly connected to the surface of the fixing blocks 17. The end of the spring 18 away from the fixing blocks 17 is fixedly connected to the locking frame 16.

[0024] As a technical optimization of this utility model, a reliable sealing and locking structure is formed by the cover plate 14 hinged to the top and back of the storage box 9, the limiting blocks 15 on both sides of the front, the insertion port, the sliding grooves on both sides of the front of the storage box 9, the locking frame 16, the fixing block 17, and the spring 18. During transportation, the locking frame 16 is inserted into the insertion port, which can firmly fix the cover plate 14 to the storage box 9, preventing the cover plate 14 from being accidentally opened and causing the sample to spill or be contaminated by the outside. At the same time, the elasticity of the spring 18 allows the locking frame 16 to be stably kept in the locked state, and when it is necessary to open the cover plate 14, simply pull the locking frame 16 gently to overcome the elasticity of the spring 18. The operation is convenient and quick, effectively improving the convenience and safety of the device.

[0025] refer toFigure 3 A protective pad 11 is fixedly connected to the inner wall of the placement opening 13, and the protective pad 11 fits into the placement rack 12.

[0026] As a technical optimization of this utility model, the protective pad 11 fixed to the inner wall of the placement opening 13 is attached to the placement rack 12. When placing and taking out the sample placement rack 12, the protective pad 11 can prevent the placement rack 12 and the sample storage container on the surface of the placement rack 12 from directly rubbing and colliding with the inner wall of the placement opening 13, preventing damage to the sample placement rack 12 and the sample storage container on the surface of the placement rack 12, thereby protecting the soil sample in the sample storage container on the surface of the placement rack 12 from the impact caused by external force collision, and further enhancing the protective performance of the soil sample.

[0027] refer to Figure 1 Handles 19 are fixedly connected to both sides of the top of the cover plate 14, and handles 20 are hinged to both sides of the storage box 9.

[0028] As a technical optimization of this utility model, the handle 19 on the top of the cover plate 14 makes it easy for operators to open and close the cover plate 14, saving operating effort; the handles 20 hinged on both sides of the storage box 9 make the entire storage device easy to carry. Whether at the sample collection site or during transportation, operators can lift the storage box 9 through the handles 20, which greatly improves the convenience of using the device and facilitates the transfer and management of samples.

[0029] refer to Figure 1 Both sides of the top of the base plate 1 are fixedly connected to buffers 21, and the end of the buffer 21 away from the base plate 1 is fixedly connected to the support plate 4.

[0030] As a technical optimization of this utility model, the buffer performance of the device is further enhanced by the buffers 21 on both sides of the top of the base plate 1. When encountering large vibrations or bumps, the buffers 21 can absorb and dissipate more vibration energy, working in conjunction with components such as the cylinder 2, the movable rod 3, and the compression spring 7 to provide more comprehensive and effective buffer protection for the storage box 9, reducing the impact of vibration on the sample and ensuring the stability of the soil sample during transportation. The buffers 21 play a role in damping and shock absorption. The aforementioned buffers 21 are common existing technologies and will not be described in detail in this application.

[0031] refer to Figure 4 A handle 22 is fixedly connected to the top of the shelf 12, and the top of the handle 22 is attached to the bottom of the cover plate 14.

[0032] As a technical optimization of this utility model, the handle 22 on the top of the placement rack 12 facilitates the operator's handling of the rack 12. When it is necessary to remove or place soil samples, the operator can easily lift or lower the placement rack 12 using the handle 22, avoiding direct contact with the samples inside the rack 12 and preventing contamination or damage to the samples. At the same time, the design of the top of the handle 22 fitting snugly against the bottom of the cover plate 14 makes the placement rack 12 more stable inside the storage box 9, preventing the rack 12 from shaking up and down inside the storage box 9 and ensuring the safety of sample storage.

[0033] The working principle and usage process of this utility model are as follows: Sample placement: First, place the storage box 9 on a stable tabletop, open the cover 14, pull the locking bracket 16 to disengage it from the insertion port of the limiting block 15, and flip the cover 14 backward. Then, according to the soil sample's testing items, collection location, or depth, place the sample in the sample storage container, with each sample placed on a different placement rack 12 surface. Next, grasp the handle 22 at the top of the placement rack 12 and insert it sequentially into the placement opening 13 of the positioning block 10. Because the protective pad 11 on the inner wall of the placement opening 13 fits snugly against the placement rack 12, it ensures the placement rack 12 is securely placed without damaging the sample. The sample storage container fits snugly against the protective pad 11. After all samples are placed, the cover 14 is flipped forward so that the insertion port of the limiting block 15 aligns with the sliding groove on the front of the storage box 9. The locking frame 16 is released, and under the action of the spring 18, the locking frame 16 is inserted into the insertion port, firmly locking the cover 14 and completing the sample storage. Identification stickers can be pasted on the top of the positioning block 10 and around each placement port 13. The operator can write content on the surface of the identification sticker to mark the sample information in each placement port 13, thereby facilitating the identification and differentiation of different samples.

[0034] Device Handling: When the storage device needs to be moved, the operator can hold the hinged handles 20 on both sides of the storage box 9 and lift the storage box 9 for transfer. During the handling process, the cylinder 2, movable rod 3, compression spring 7, and buffer 21 on the top of the base plate 1 will work together to effectively buffer the vibration and collision generated during the handling process and protect the soil sample inside the storage box 9 from damage.

[0035] Sample Retrieval: Upon arrival at the testing location, follow the procedure for opening cover 14 by pulling the locking bracket 16 to open cover 14. Depending on the testing requirements, grasp the handle 22 at the top of the placement rack 12 and remove the corresponding rack from the placement opening 13 for soil sample analysis. After testing, if sample storage is required, repeat the sample placement procedure to re-store the sample in the storage box 9.

[0036] When the device is subjected to vibration, the cylinders 2 around the top of the base plate 1 and the movable rod 3 form a sliding structure, allowing the movable rod 3 to slide up and down along the cylinders 2. Simultaneously, the sliding groove, slider 5, connecting rod 6, and compression spring 7 on the top of the base plate 1 form a linkage mechanism. The slider 5 slides within the sliding groove, causing the connecting rod 6 to swing, and the compression spring 7 undergoes elastic deformation. These three components work together to disperse and buffer the external force generated by the vibration. The buffers 21 on both sides of the top of the base plate 1 also function synchronously, further absorbing and dissipating the vibration energy. These buffer structures weaken the vibration energy layer by layer, reducing the impact force transmitted to the support plate 4, while the buffer pad 8 on the top of the support plate 4 can mitigate the impact of the remaining vibration on the storage box 9. The protective pad 11 on the inner wall of the placement opening 13 inside the storage box 9 fits into the placement rack 12. During vibration, the protective pad 11 can prevent the placement rack 12 from colliding with the inner wall of the placement opening 13. At the same time, the top handle 22 of the placement rack 12 fits into the bottom of the cover plate 14 to prevent the placement rack 12 from shaking up and down. This provides all-round cushioning for the placement rack 12 and the sample storage container on the surface of the placement rack 12, ensuring the integrity of the soil sample to the greatest extent.
