Description

Technical Field

[0001] This utility model belongs to the technical field of water resource sample storage, specifically relating to a portable sample storage device for water resource management. Background Technology

[0002] In water resource management, the preservation and transportation of water samples after collection are key to ensuring the accuracy of test data. To standardize water sample management and improve portability, existing technologies often use portable sample storage devices (such as portable cases) to centrally store collected water sample bottles or test tubes.

[0003] Traditional portable cases are typically designed with a single-slot layout (multiple parallel fixed slots inside the case). All slots are on the same horizontal plane, and water sample bottles / tubes are inserted vertically into them. Protection is achieved through the overall seal when the case is closed. When the case is full of water samples (especially when there are many), all the tubes are arranged closely together at the same height. Staff must bend over to observe the labels one by one and accurately locate the target tube. If the spacing between the tubes is small, the dense arrangement on the same plane can cause the labels of adjacent tubes to easily obscure each other, making it difficult for staff to quickly read the water sample information (such as sampling location and time), increasing the risk of mistaking or missing samples. Furthermore, when retrieving samples, staff must use their fingers to push aside surrounding tubes one by one to retrieve the target sample, which is cumbersome and time-consuming. This is especially true in field or emergency sampling scenarios (such as when rapid screening of multiple water samples is required in the event of a sudden water pollution incident), which seriously affects work efficiency. If the spacing between the tubes is large, it wastes space inside the case, and a large case is required when carrying a large number of tubes, making it inconvenient to carry. Utility Model Content

[0004] The purpose of this invention is to provide a portable sample storage device for water resource management, aiming to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A portable water resource management sample storage device includes a layered component, a storage box, a top cover rotatably connected to the storage box via a pivot, a handle on the top of the top cover, a placement slot inside the storage box for inserting test tubes, and a snap fastener on the front of the storage box and the top cover for easy closure. The storage box also includes a layered assembly adapted to fit the test tubes. A positioning component includes a mounting plate that slides left and right inside the storage box, with a rubber strip fixedly connected to the side of the mounting plate closest to the test tubes.

[0006] In a preferred embodiment of this utility model, the layered assembly includes two rollers fixedly connected to the outside of the rotating shaft, with pull ropes fixedly connected to the outside of each of the two rollers. A lifting plate is slidably connected to the inside of the storage box, with a top column fixedly connected to the top of the lifting plate. Four steering rollers are rotatably connected to the inside of the storage box. Anti-detachment plates are slidably connected to the inside of the left and right sides of the storage box, with positioning blocks fixedly connected to the inner sides of each of the two anti-detachment plates.

[0007] As a preferred embodiment of this utility model, positioning grooves are provided at both ends of the rotating shaft of the top cover and at the corresponding positions of the two positioning blocks, and the positioning blocks are inserted into the positioning grooves. The positioning blocks are rectangular.

[0008] In a preferred embodiment of this utility model, the end of the pull rope away from the wire roller is turned by two turning rollers and then fixedly connected to the top of the lifting plate, and the diameters of the placement groove, test tube and top column gradually decrease.

[0009] In a preferred embodiment of this invention, the top column is positioned directly below the test tube, and the center-to-center distance between the two top columns is twice the center-to-center distance between the two corresponding test tubes.

[0010] In a preferred embodiment of this utility model, a connecting rod is fixedly connected to the top of the lifting plate, a movable column is fixedly connected to the top of the connecting rod, and a movable inclined groove is provided inside the mounting plate.

[0011] In a preferred embodiment of this invention, the movable column is movably connected inside the movable inclined groove, and the rubber strip abuts against the outside of the test tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The staggered lifting design of the top column allows some test tubes to be raised while others remain low, creating a staggered arrangement that facilitates quick identification and retrieval of target test tubes, effectively improving sampling efficiency and reducing the risk of mis-receiving or missing test tubes.

[0013] 2. The rotating shaft linkage roller and pull rope drive the lifting plate and top column to rise and fall vertically. While opening the top cover, the test tubes are automatically lifted in layers. The operation is smooth and convenient, and there is no need to manually move the test tubes. This significantly simplifies the sampling process and improves the user experience.

[0014] 3. The positioning component drives the rubber strip away from or against the test tube through the movable inclined groove and connecting rod. This not only stabilizes and protects the test tube during movement and prevents collision damage, but also releases the test tube for easy retrieval during sampling, thus balancing the stable storage and flexible use of the test tube.

Detailed Implementation

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1 Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a portable sample storage device for water resource management, including a layered component, including a storage box 10. The top of the storage box 10 is provided with a top cover 11 that is rotatably connected to the storage box 10 via a rotating shaft. The top of the top cover 11 is provided with a handle 12. The inside of the storage box 10 is provided with a placement slot 13, and a test tube 14 is inserted into the placement slot 13. The front of the storage box 10 and the top cover 11 are provided with a buckle 15 to facilitate the closure of the two. The inside of the storage box 10 is provided with a layered component 16 that is adapted to the test tube 14.

[0019] The test tube 14 has a label on the front, which makes it easy to distinguish multiple test tubes 14 as needed, and also makes it accurate and quick to pick up the test tube 14. The diameter of the placement groove 13 is slightly larger than that of the test tube 14, making it easier to insert and pick up the test tube 14.

[0020] Furthermore, the layered assembly 16 includes two thread rollers 161 fixedly connected to the outside of the rotating shaft. Each of the two thread rollers 161 is fixedly connected to a pull rope 162. The storage box 10 is slidably connected to the inside of the storage box 10. A top column 164 is fixedly connected to the top of the lifting plate 163. Four steering rollers 165 are rotatably connected to the inside of the storage box 10. Anti-detachment plates 166 are slidably connected to the inside of the left and right sides of the storage box 10. Positioning blocks 167 are fixedly connected to the inside of the two anti-detachment plates 166. Positioning grooves are opened at both ends of the rotating shaft of the top cover 11 and at the corresponding positions of the two positioning blocks 167. The positioning blocks 167 are inserted into the positioning grooves and are rectangular.

[0021] The rectangular design of the positioning block 167 allows the top cover 11 to be re-inserted into the rotating shaft of the top cover 11 after rotating 180 degrees, and the top cover 11 can no longer be rotated, making it easy to retrieve the test tube 14 inside the storage box 10. The anti-detachment plate 166 and the top cover 11 are both provided with buckle grooves to facilitate the movement of the top cover 11 and the anti-detachment plate 166. At the same time, the pull rope 162 drives the lifting plate 163 to move vertically under the action of the two turning rollers 165.

[0022] Preferably, the end of the pull rope 162 away from the wire roller 161 is turned by two turning rollers 165 and then fixedly connected to the top of the lifting plate 163. The diameters of the placement groove 13, test tube 14 and top column 164 gradually decrease. The top column 164 is located directly below the test tube 14, and the center distance between the two top columns 164 is twice the center distance between the corresponding two test tubes 14.

[0023] It should be noted that the number of top pillars 164 is half the number of test tubes 14 and they are spaced apart, so that the height of test tubes 14 without top pillars 164 at the bottom remains unchanged, while the height of test tubes 14 with top pillars 164 at the bottom is raised, so as to achieve staggered lifting of the top pillars 164, thereby making the multiple test tubes 14 appear staggered.

[0024] In use, test tubes 14 are initially inserted into the placement slots 13 for storage. The top of the test tube 14 abuts against the top cover 11, and the bottom of the test tube 14 abuts against the bottom of the placement slot 13. Simultaneously, the bottoms of the spaced-apart test tubes 14 also abut against the top post 164. Multiple test tubes 14 can be carried by lifting the handle 12, making it convenient to carry. To retrieve a test tube 14, pull the two anti-detachment plates 166 to the sides, causing the anti-detachment plates 166 to disengage from the pivot inside the top cover 11. Then, open the two latches 15 to retrieve the test tube. The top cover 11 opens (releasing the pressure on the top of the test tube 14). At this time, the top cover 11 rotates around the pivot, which drives the roller 161 to rotate, causing the pull rope 162 to wrap around the outside of the roller 161. The pull rope 162 pulls the lifting plate 163 upward, and the lifting plate 163 drives the top column 164 to rise, lifting the test tube 14. Since the number of top columns 164 is half the number of test tubes 14 and they are spaced apart, the height of the test tube 14 without top columns 164 at the bottom remains unchanged. The test tubes 14 with the top column 164 are raised, so that multiple test tubes 14 are arranged in a staggered, non-uniform, and layered manner, which facilitates quick access to the test tubes 14. This avoids the problem of all test tubes 14 being arranged closely at the same height on the same plane. In this case, the staff would have to bend over and look down to observe the labels one by one and accurately locate the target test tube 14. The labels of adjacent test tubes 14 would easily obscure each other, making it difficult for the staff to quickly read the water sample information and increasing the risk of mistaking or missing test tubes. In addition, when taking them out, the staff would have to use their fingers to push aside the surrounding test tubes 14 one by one to take out the target test tube 14. This operation was cumbersome and time-consuming, which seriously affected the work efficiency. The method of taking out test tubes 14 is more convenient. After the top cover 11 is rotated 180 degrees, the two anti-detachment plates 166 are pushed inward, so that the two positioning blocks 167 are inserted into the two ends of the rotating shaft. This prevents the lifting plate 163 from causing the top cover 11 to rotate under the weight of the sample in the test tube 14, which would affect the continuous access to the test tubes 14. This further improves the portability.

[0025] Example 2 Reference Figures 7-8 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a positioning component, including a mounting plate 20 that is slidably connected to the inside of the storage box 10. A rubber strip 21 is fixedly connected to the side of the mounting plate 20 near the test tube 14. A connecting rod 22 is fixedly connected to the top of the lifting plate 163. A movable column 23 is fixedly connected to the top of the connecting rod 22. A movable inclined groove 24 is formed inside the mounting plate 20. The movable column 23 is movably connected inside the movable inclined groove 24. The rubber strip 21 abuts against the outside of the test tube 14. In use, the lifting plate 163 rises, causing the connecting rod 22 to rise, so that the movable column 23 moves inside the movable inclined groove 24. Since the movable inclined groove 24 is inclined, when the movable column 23 moves inside the movable inclined groove 24, it causes the mounting plate 20 to move away from the test tube 14, so that the rubber strip 21 no longer abuts against the test tube 14. The diameter of the placement groove 13 is slightly larger than the diameter of the test tube 14, making it easier to pick up the test tube 14. Similarly, when the top cover 11 is closed, the lifting plate 163 descends, causing the rubber strip 21 to abut against the outside of the test tube 14. Each test tube 14 has two symmetrical rubber strips 21 abutting against the outside, so that the test tube 14 is firmly inserted into the inside of the placement groove 13. When the storage box 10 is lifted to move the test tube 14, the test tube 14 will not shake or hit inside the placement groove 13, thus protecting the test tube 14 and achieving stable storage of the test tube 14, extending its service life.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
