Description

Technical Field

[0001] This utility model belongs to the field of soil sampling technology, specifically an environmental monitoring soil sampling device. Background Technology

[0002] Environmental soil monitoring is a crucial step in assessing soil health and pollution status. Its core components are sampling and storage, which directly determine the accuracy and representativeness of the monitoring results. Sampling must adhere to strict standards, selecting appropriate sampling points at different depths based on the monitoring objective and soil type. Sample storage after collection is essential for subsequent laboratory analysis and potential verification. Samples must be preserved in a low-temperature, light-protected, and dry environment to maximize the preservation of their original physicochemical properties and pollutant content, preventing degradation, volatilization, or moisture absorption during storage and ensuring the reliability of analytical results. However, existing sample storage tubes are not stable and are prone to tipping over, causing sample spillage. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: an environmental monitoring soil sampling device, comprising a sleeve, a sampling tube movably inserted into the top of the sleeve, a sealing cap movably inserted into the top of the sampling tube, inverted T-shaped sliding mounting grooves on both sides of the sleeve, large sliders installed inside the two inverted T-shaped sliding mounting grooves, two connecting shafts rotatably installed on one side of the two large sliders, n-shaped rods fixedly installed between the two connecting shafts at the same position on the two large sliders, and abutment blocks for pressing the sealing caps fixedly installed on the upper inner side of the two n-shaped rods.

[0004] Preferably, both sides of the two inverted T-shaped sliding mounting grooves are provided with right-angled triangular limiting slots, and the middle of the upper part of the two large sliders is provided with a horizontally penetrating cross groove. Two small sliders are slidably installed in the middle of the cross grooves. A spring layer is installed between the two small sliders, and an insert is fixedly connected to the opposite end of the two small sliders. The lower part of the opposite end of the two inserts is provided with an inclined surface that matches the right-angled triangular limiting slot, and the insert is movably inserted into the inside of the right-angled triangular limiting slot. The upper part of the two inverted T-shaped sliding mounting grooves is provided with a sliding groove that communicates with the middle of the cross groove. A toggle block that penetrates the inside of the sliding groove is fixedly installed on one side of the small slider, and the toggle block extends to the outside of one side of the inverted T-shaped sliding mounting groove.

[0005] Preferably, the surfaces of the two connecting shafts on the two large sliders are fixedly mounted with meshing gears, and isosceles trapezoidal blocks for limiting and blocking are fixedly mounted on both sides of the sleeve.

[0006] Preferably, a fixing block is fixedly installed on one of the large sliders, a threaded pin is threadedly connected to the middle of the fixing block, one end of the threaded pin is rotatably connected to a toothed block that matches the gear through a bearing, and the other end of the threaded pin is fixedly connected to a rotating block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This sample storage device has a support and adjustment structure, which can reliably support the sample storage tube, prevent the sample storage tube from tipping over during use and improve stability. At the same time, the support and adjustment structure also has an auxiliary pressing and sealing function, which effectively ensures the effectiveness of sample storage in the sample storage tube.

[0008] When using the sample storage tube, first move the two actuating blocks on the two large sliders to make the two actuating blocks move relative to each other, which in turn moves the two small sliders relative to each other and compresses the spring layer. The relatively moving small sliders will move the insert block, causing the insert block to move out of the inside of the right-angled triangular limiting slot. Then, the large slider can be moved upward inside the inverted T-shaped sliding mounting slot, thereby separating the two abutting blocks from the top of the sealing cap.

[0009] By rotating one of the n-shaped rods, the rotation of the one n-shaped rod drives the other n-shaped rod to rotate synchronously through the connecting shaft and meshing gears. Eventually, the two n-shaped rods rotate in opposite directions and come into contact with the isosceles trapezoidal block. Then, rotating the rotating block drives the threaded pin to rotate and move. The rotation and movement of the threaded pin pushes the locking block to move, so that the locking block limits and fixes one of the gears, thereby effectively keeping the two unfolded n-shaped rods stable. Then, the two unfolded n-shaped rods can stably support and place the tube sleeve and the sample storage tube. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Depend on Figures 1 to 5 The present invention includes a sleeve 1, which is a hollow tubular structure with an open top. A sample storage tube 2 is movably inserted into the top of the sleeve 1, and a sealing cap 3 is movably inserted into the top of the sample storage tube 2. A rubber ring is provided at the bottom of the sealing cap 3 to seal the top of the sample storage tube 2. Inverted T-shaped sliding mounting grooves 4 are provided on both sides of the sleeve 1. Large sliders 5 are installed inside the two inverted T-shaped sliding mounting grooves 4. Two connecting shafts 6 are rotatably installed on one side of the two large sliders 5. An n-shaped rod 7 is fixedly installed between the two connecting shafts 6 at the same position on the two large sliders 5. A contact block 8 is fixedly installed on the upper part of the inner side of the two n-shaped rods 7 to press the sealing cap 3.

[0020] Both sides of the two inverted T-shaped sliding mounting grooves 4 are provided with right-angled triangular limiting slots 9. The right-angled triangular limiting slots 9 on both sides of the inverted T-shaped sliding mounting grooves 4 are symmetrically arranged. The middle of the upper part of the two large sliders 5 is provided with a horizontally penetrating cross groove 10. Two small sliders 11 are slidably installed in the middle of the cross groove 10. A spring layer 12 is installed between the two small sliders 11. The opposite ends of the two small sliders 11 are fixedly connected with inserts 13. The lower part of the opposite ends of the two inserts 13 is provided with a slope that matches the right-angled triangular limiting slot 9. The inserts 13 are movably inserted into the inside of the right-angled triangular limiting slot 9. The upper part of the two inverted T-shaped sliding mounting grooves 4 is provided with a sliding groove 14 that communicates with the middle of the cross groove 10. A toggle block 15 that penetrates the inside of the sliding groove 14 is fixedly installed on one side of the small sliders 11. The toggle block 15 extends to the outside of one side of the inverted T-shaped sliding mounting groove 4, so as to effectively move and adjust the large sliders 5.

[0021] Specifically, see the attached diagram. Figure 1 , Figure 3 and Figure 4 As shown, the insert 13 is inserted into the right-angled triangular limiting slot 9, and at the same time, the two abutting blocks 8 press and fix the top of the sealing cover 3, so that the sealing cover 3 can tightly seal the top of the sample storage tube 2, thereby ensuring the airtightness of the sample storage.

[0022] When using the sample storage tube 2 to store samples, first move the two actuating blocks 15 on the two large sliders 5 so that the two actuating blocks 15 move relative to each other, thereby driving the two small sliders 11 to move relative to each other and compressing the spring layer 12. The relatively moving small sliders 11 will drive the insert block 13 to move, so that the insert block 13 moves out of the inside of the right-angled triangular limiting groove 9. Then, the large sliders 5 can be moved upward inside the inverted T-shaped sliding mounting groove 4, thereby separating the two abutting blocks 8 from the top of the sealing cover 3.

[0023] Two connecting shafts 6 on the two large sliders 5 are fixedly mounted with meshing gears 16. Isosceles trapezoidal blocks 17 for limiting and blocking are fixedly mounted on both sides of the sleeve 1. A fixing block 18 is fixedly mounted on one of the large sliders 5. A threaded pin 19 is threadedly connected to the middle of the fixing block 18. One end of the threaded pin 19 is rotatably connected to a toothed block 20 that matches the gear 16 through a bearing. The toothed block 20 slides in contact with the large slider 5. A rotating block 21 is fixedly connected to the other end of the threaded pin 19, so that the two n-shaped rods 7 can be rotated and unfolded to provide stable support.

[0024] Specifically, when the tube sleeve 1 and sample storage tube 2 need to be stably placed, and the two contact blocks 8 separate from the sealing cap 3, rotating one of the n-shaped rods 7 will cause the other n-shaped rod 7 to rotate synchronously via the connecting shaft 6 and the meshing gear 16. Ultimately, the two n-shaped rods 7 rotate in opposite directions and contact the isosceles trapezoidal block 17. Then, rotating the rotating block 21 will cause the threaded pin 19 to rotate and move. The rotation of the threaded pin 19 will push the locking block 20 to move, so that the locking block 20 limits and fixes one of the gears 16, thereby effectively maintaining the stability of the two unfolded n-shaped rods 7. The two unfolded n-shaped rods 7 can then stably support and place the tube sleeve 1 and sample storage tube 2, as shown in the attached diagram. Figure 2 and Figure 5 As shown.

[0025] This sample storage device features a support and adjustment structure that reliably supports the sample tube, preventing it from tipping over during use and improving stability. This structure also provides auxiliary compression and sealing, effectively ensuring the validity of the stored samples. Furthermore, the device has a simple design, is easy to use and operate, and offers stable and reliable support and compression. Its performance meets the requirements for soil sample storage in environmental monitoring.
