Description

Technical Field

[0001] This invention relates to the field of soil and water sample storage, and in particular to a sample storage device for environmental soil and water sample testing. Background Technology

[0002] Currently, existing environmental testing sample storage devices have a relatively simple structural design and poor adaptability, making it difficult to meet the integrated storage needs of various types of soil and water samples. Most existing storage devices are fixed slots with fixed aperture limiting structures, and the slot spacing and capacity are not adjustable. They can only accommodate sample containers of a single size and type, and are incompatible with soil sampling tanks and water sampling bottles that vary greatly in size and shape. In actual operation, multiple storage devices are needed to store different samples separately, resulting in large equipment footprints, high transportation and maintenance costs, and significantly reducing the efficiency of environmental sampling and testing.

[0003] Meanwhile, the existing sample storage devices suffer from insufficient stability in their limiting and fixing structures. Most rely solely on simple placement and snap-fit ​​fastening to secure the containers, making them prone to shaking, shifting, and tipping during field transport and equipment handling. This not only easily leads to water sample leakage and soil sample spillage, resulting in sample contamination, loss, and scrapping, thus hindering the normal progress of testing, but also poses safety hazards due to container collisions and breakage. For small containers such as centrifuge tubes and miniature sampling bottles, there is a risk of them falling off and being lost; for large-capacity water sample bottles and heavy soil sampling containers, there are issues with insecure clamping and uneven stress, making it difficult to guarantee the safety and reliability of sample storage.

[0004] Furthermore, traditional storage devices suffer from poor structural flexibility and limited functionality, failing to adjust storage space and limiting structures in real time according to sample quantity and container specifications, thus restricting their applicability to various scenarios. Therefore, this paper proposes a sample storage device for environmental soil and water sample testing. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention proposes a sample storage device for environmental soil and water sample testing. This device solves the problems of fixed specifications, poor adaptability, inability to adapt to various types of soil and water sample containers, unstable fixation, inconvenience in handling, and easy sample contamination associated with existing storage devices.

[0014] Preferably, the adjusting assembly includes a gear ring, a gear, a screw, a sleeve seat, a slide bar bracket, a sleeve frame, a guide rod, and a slide block. The gear ring is fitted onto the inner wall of the sleeve ring.

The sleeve seats are connected in pairs to both radial sides of the upper end face of the rotating ring. The slide bar bracket is slidably fitted onto each set of sleeve seats. The sleeve frame is connected to the two sides of the two slide bar brackets on the adjacent sides of the two sleeve seats.

[0018] The beneficial effects of this invention are:

[0019] 1. The technical solution of this invention involves rotating a bidirectional lead screw to move the sliding plates on the front and rear sides away from each other, thereby pulling the rotating plate to move the frame down at the bottom of the hollow interlayer, which in turn moves the bottom cover down and opens the bottom hole at the bottom of the storage slot. At the same time, through transmission, the bidirectional lead screw rotates, causing the connecting blocks on both sides of the slider to move away from each other and cancel their locking positions with the locking blocks on the cover, making it easier to open and remove the cover. Furthermore, by squeezing the deformation buckles on both sides of each inner cover to squeeze them together, the inner covers above each storage slot in the corresponding row can be removed, allowing the sample containers for soil or water samples below the inner cover in the storage slot to be placed or removed. Especially when removing sample containers, this setting does not require opening all storage slots, but only opening the storage slots in the corresponding row that only store the same type of sample, such as soil or water samples, avoiding interference with the air intake of other storage slots, improving storage effect and ease of use and retrieval.

[0020] 2. The technical solution of the present invention rotates the rotating ring, causing the rotating ring to rotate relative to the collar. The gear inside the rotating ring, which meshes with the inner toothed ring of the collar, will rotate through meshing, thereby driving the screw to rotate. The rotation of the screw can drive the slide block to slide up and down, thereby driving the rotating plate two to rotate, and pushing the sleeve frame and the slide rod frame one to slide radially along the rotating ring on the sleeve plate seat. This drives the slide rod frame two and the clamping plate, which are slidably mounted on the sleeve frame, to slide radially along the rotating ring, thereby adjusting the distance between the two clamping plates. When a sample container is contained, the sample container can compress the spring one by contacting the clamping plate, and then be pressed by the reaction force of the spring one, and be stably stored in the storage groove without shaking or displacement. When the sample container is of different sizes, the distance between the two sleeve frames can be adjusted to indirectly adjust the distance between the two clamping plates, so that when the sample container and the clamping plate contact and lock in place, the spring one can be compressed with sufficient stroke to obtain stability, thus achieving the versatility of stably storing different sample containers.

[0021] 3. The technical solution of this invention, during the opening of the box lid, causes the frame to move downwards, allowing the bottom cover and its internal sliding square slider and cross-shaped insert to slide downwards. This causes the cross-shaped insert to be pulled out of the cross slot with the ring frame, thereby eliminating the locking of the ring frame and the rotating ring. This allows the spacing between the two side frames to be adjusted by rotating the rotating ring when taking out or placing the sample container, especially during storage, ensuring that the locking plate can securely lock the sample container. When the two side sliding plates are moved closer together to close the box lid onto the storage box and lock it in place, the frame and bottom cover can be pushed upwards, causing the bottom cover to seal the bottom hole, preventing the sample in the sample container from leaking into the hollow interlayer. At the same time, it can also drive the cross-shaped insert to move upwards and be inserted into the cross slot, thereby limiting the rotation ring during storage and effectively improving storage stability.

[0032] The following will be combined with the appendix Figure 1 To be continued Figure 8 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: As Figures 1-8 As shown, the present invention discloses a sample storage device for environmental soil and water sample testing, including a storage box 1 and a box cover 2. The storage box 1 is provided with a hollow interlayer 3. The storage box 1 has multiple rows of receiving circular grooves 4. The bottom of the receiving circular grooves 4 is provided with bottom holes 8 that penetrate the bottom of the hollow interlayer 3. A frame 9 is slidably provided at the bottom of the hollow interlayer 3. Bottom covers 10 are connected to the frame 9 and respectively fitted and sealed with each bottom hole 8. Slide plates 12 are slidably provided on the front and rear sides of the hollow interlayer 3. The front and rear ends of each slide plate 12 are rotatably connected to the front and rear sides of the frame 9 with a rotating plate 13. A bidirectional screw 14 is also rotatably installed at the bottom of the hollow interlayer 3 that penetrates the front and rear sides of the storage box 1. The slide plates 12 on the front and rear sides are respectively threaded with the bidirectional screw 14 on the front and rear sides. A locking block 23 is slidably provided on the front and rear sides of the storage box 1.

[0034] The front and rear sides of the lid 2 are connected to a second locking block 24 that engages with the first locking block 23. A linkage component is installed in the hollow interlayer 3. The linkage component is used to drive the first locking blocks 23 on both sides to move closer or further apart when the bidirectional lead screw 14 rotates, so as to engage or separate from the second locking block 24. Each storage circular groove 4 is fitted with a collar 25. A rotating ring 27 is rotatably fitted inside the collar 25. The rotating ring 27 has a locking plate 37 that is radially slidably arranged on both sides to lock the sample container. An adjustment component is provided on the rotating ring 27 to adjust the force of the locking plates 37 on both sides to lock the sample container. The bottom cover 10 is also provided with a locking component to limit the rotation ring 27.

[0035] Each row of storage slots 4 is arranged at equal intervals. The bottom of the storage box 1 is threaded with a cover 46 that is connected to the hollow interlayer 3. The bottom hole 8 is a stepped hole, and the bottom cover 10 is also a stepped cover.

[0036] The corresponding step setting can ensure the sealing effect of the bottom cover 10 and the bottom hole 8, and prevent the sample in the sample container in the collection groove 4 from leaking into the hollow interlayer 3.

[0037] The storage box 1 has slots 5 connected to the front and rear inner walls of each row of storage slots 4. Each row of storage slots 4 has an inner cover 6 located below the box cover 2 inside the storage box 1. Each inner cover 6 seals the upper end of the corresponding row of storage slots 4. The front and rear sides of the inner cover 6 are connected to deformable buckles 7 that cooperate with the slots 5.

[0038] This design allows for easy removal of the inner covers 6 above the corresponding storage slots 4 after opening and removing the cover 2. The inner covers 6 can be squeezed together by pressing the deformation latches 7 on both sides of each inner cover 6 to deform and release their locking mechanism from the slots 5. This facilitates the removal of the inner covers 6 from the storage slots 4 below the inner covers 6, allowing for the placement and removal of soil or water sample containers within the storage slots 4. Especially when removing sample containers, this design eliminates the need to open all storage slots 4; only the corresponding slots 4 containing only the same type of sample, such as soil or water samples, are opened. This prevents interference with air intake in other storage slots 4, improving storage efficiency and ease of use.

[0039] The bottom left and right sides of the hollow interlayer 3 are connected with parallel guide rods 11. The two ends of the slide plate 12 are slidably sleeved on the outside of the guide rods 11. The two-way screw 14 has opposite threads at the front and rear ends inside the hollow interlayer 3. The slide plates 12 on the front and rear sides are symmetrically threaded on the front and rear ends of the two-way screw 14. The front and rear ends of the two-way screw 14 are also sealed and rotated through the front and rear sides of the storage box 1.

[0040] Ensure that when rotating the bidirectional lead screw 14, the two sliding plates 12 on both sides can stably move closer to or further away from each other.

[0041] Example 2: Figures 1-8As shown, the present invention discloses a sample storage device for environmental soil and water sample testing. Compared with Embodiment 1, this embodiment discloses the structure of the linkage component.

[0042] The linkage assembly includes a lower pulley 15, an upper pulley 16, a belt 17, a double-acting screw 20, a bevel gear 21, and a slider 22. The lower pulley 15 is arranged in two positions, front and back, and is symmetrically fitted at the front and back ends of the double-acting screw 14. The upper pulley 16 is rotatably fitted on the front and back inner walls of the hollow interlayer 3. The upper pulleys 16 on the front and back sides rotate through the front and back sides of the storage box 1 at their far ends, extending to the front and back outer sides of the storage box 1. A bevel gear 18 is fitted at the extended end. The belt 17 is fitted on the outside of the lower pulley 15 and the upper pulley 16 on the same front and back sides. The double-acting screw 20 is arranged in two parallel positions, front and back, and is rotatably installed on the front and back outer sides of the storage box 1. The bevel gear 21 is fitted on the outside of the double-acting screw 20 and meshes with the bevel gear 18. The slider 22 is threaded at both ends of each double-acting screw 20. A locking block 23 is connected to the upper end of the slider 22. A locking block 24 is located between the two locking blocks 23 and engages with the two locking blocks 23 to lock in place.

[0043] By rotating the bidirectional lead screw 14, the front and rear sliding plates 12 are moved away from each other, which pulls the rotating plate 13 to move the frame 9 to slide down at the bottom of the hollow interlayer 3, thereby moving the bottom cover 10 down and opening the bottom hole 8 at the bottom of the storage groove 4. At the same time, through the transmission of the lower pulley 15, belt 17 and upper pulley 16, the bevel gear 18 and bevel gear 21 are driven to mesh, thereby causing the bidirectional lead screw 20 to rotate, and simultaneously driving the left and right sliders 22 to slide away from each other. This causes the connecting blocks 23 on the sliders 22 to move away from each other and cancel their locking positions with the locking blocks 24 on the cover 2, so as to facilitate opening and removing the cover 2.

[0044] The upper pulley 16 is sealed and rotated through the front and rear sides of the storage box 1. The front and rear sides of the storage box 1 are symmetrically connected with a frame 19. The two ends of the bidirectional screw 20 are rotated and fitted on the inner walls of the two sides of the frame 19. The threads on the outer sides of the two ends inside the frame 19 are opposite. The sliders 22 on both sides are symmetrically threaded and fitted on the outer sides of the two-way screw 20 and slidably fitted inside the frame 19.

[0045] The bidirectional lead screw 20 ensures that the sliders 22 threaded on the outer ends of its two ends move closer or further apart synchronously. At the same time, the front and rear ends of the bidirectional lead screw 14 are sealed and rotated through the front and rear sides of the storage box 1, and the upper pulley 16 is sealed and rotated through the front and rear sides of the storage box 1 to ensure the airtightness of the hollow interlayer 3, so that the hollow interlayer 3 has a stable heat preservation effect.

[0046] Example 3: Figures 1-8As shown, the present invention discloses a sample storage device for environmental soil and water sample testing. Compared with Embodiment 2, this embodiment discloses the structure of the adjustment component.

[0047] The adjusting assembly includes a gear ring 26, a gear 28, a screw 29, a sleeve base 30, a slide bar bracket 31, a sleeve frame 32, a guide rod 33, and a slide block 34. The gear ring 26 is fitted onto the inner wall of the sleeve ring 25. The gear 28 is arranged on both sides radially along the rotating ring 27 and is rotatably fitted inside the rotating ring 27, with the gear 28 meshing with the gear ring 26. The screw 29 is connected to the upper end of the gear 28, and the screw 29 rotates through the upper end face of the rotating ring 27. Two sleeve bases 30 are connected to the rotating ring 27. On the upper radial sides, slide rod bracket 31 is slidably sleeved on each set of sleeve base 30. Sleeve frame 32 is connected to the two sides of slide rod bracket 31 on the side of sleeve base 30 that are close to each other. Guide rod 23 is connected to the upper radial sides of the ring 27. Slide seat 34 is threadedly sleeved on the upper end of each screw 29 on the ring 27, and slide seat 34 is also slidably sleeved on the outside of guide rod 23. Rotary plate 25 is rotatably connected between each slide seat 34 and sleeve frame 32.

[0048] The two side plates 37 are connected to the sliding rod bracket 36 on the opposite side, and the opposite ends of the two side sliding rod brackets 36 slide through the sleeve frame 32 on their respective sides. A spring 38 is connected between the plate 37 and the sleeve frame 32 and is sleeved on the outside of the sliding rod bracket 36.

[0049] By rotating the rotating ring 27, the rotating ring 27 rotates relative to the collar 25. This causes the gear 28, which rotates within the rotating ring 27 and meshes with the internal gear ring 26 of the collar 25, to rotate. This rotation, in turn, drives the screw 29 to rotate. The rotation of the screw 29 causes the slide block 34, which is threaded onto it and slidably fitted with the guide rod 33, to slide up and down. This, in turn, causes the rotating plate 35 to rotate, pushing the sleeve frame 32 and the slide rod bracket 31 to slide radially along the rotating ring 27 on the sleeve base 30. This, in turn, causes the slide rod bracket 36 and the clamping plate 37, which are slidably fitted on the sleeve frame 32, to slide along the diameter 27 of the rotating ring. The spacing between the two side clamping plates 37 is adjusted so that when a sample container is accommodated, the sample container can compress the spring 38 by contacting the clamping plate 37, and then be pressed tightly by the reaction force of the spring 38, so that it is stably stored in the storage groove 4 without shaking or displacement. When the sample container is of different sizes, the spacing between the two side sleeves 32 is adjusted, which indirectly adjusts the spacing between the two side clamping plates 37, so that when the sample container contacts and locks with the clamping plate 37, the spring 38 can be compressed with sufficient stroke to achieve stability, thus realizing the versatility of stable storage for different sample containers.

[0050] Example 4: Figures 1-8As shown, the present invention discloses a sample storage device for environmental soil and water sample testing. Compared with Embodiment 3, this embodiment discloses the structure of the positioning component.

[0051] The positioning assembly includes a ring frame 40, a cross slot 41, a square slide groove 42, a square slider 43, and a cross insert 45. The ring frame 40 is connected to the lower end of the rotating ring 27. The cross slot 41 is opened in the center of the ring frame 40. The square slide groove 42 is opened on each bottom cover 10, and the upper end of the square slide groove 42 passes through the upper surface of the bottom cover 10. The square slider 43 is slidably disposed in the square slide groove 42. The cross insert 45 is connected to the upper end of the square slider 43, passes through the bottom cover 10 and extends above it, and is inserted into the cross slot 41 on the ring frame 40 inside the receiving circular groove 4.

[0052] Multiple connecting rods 39 are arrayed on the lower end face of the rotating ring 27. The lower end of each connecting rod 39 is connected to the ring frame 40. A spring 44 is connected between the lower end face of the square slider 43 and the lower inner wall of the square groove 42.

[0053] During the opening of the lid 2, the downward movement of the frame 9 causes the bottom cover 10 and its internal sliding square slider 43 and cross-shaped insert 45 to slide downwards. This allows the cross-shaped insert 45 to disengage from the cross-shaped slot 41 of the ring frame 40, thereby eliminating the locking between the ring frame 40 and the rotating ring 27. This allows for easy handling of sample containers, especially during storage, by rotating the rotating ring 27 to adjust the distance between the two side frames 32, ensuring that the locking plate 37 can securely hold the sample container. When the two sliding plates 12 are brought closer together, closing the lid 2 onto the storage box 1 and locking it in place, the frame 9 and bottom cover 10 are pushed upwards, causing the bottom cover 10 to seal the bottom hole 8, preventing the sample in the sample container from entering. When the sample spills into the hollow interlayer 3, it can also cause the cross-shaped insert 45 to move upward. When the cross-shaped insert 45 can be directly inserted into the cross-shaped slot 41, it can directly limit the rotation of the rotating ring 27. When it cannot be directly inserted, during subsequent storage, when the storage box 1 shakes due to transportation, the rotating ring 27 may rotate, thereby driving the ring frame 40, the cross-shaped slot 41, and the cross-shaped insert 45 to align. Under the elastic force of the second spring 44, the cross-shaped insert 45 is lifted upward and inserted into the cross-shaped slot 41. The rotating ring 27 rotates slightly without causing large slippage of the sleeve frame 32, which can still ensure that the clamping plate 37 is clamped to the sample container, effectively improving the stability of storage.

[0054] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the protection scope of the claims of the present invention. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the present invention.
