Description

Soil sample spillage prevention storage box Technical Field

[0001] This utility model belongs to the field of preservation box technology, specifically, it relates to a soil sample preservation box to prevent spillage. Background Technology

[0002] Environmental monitoring of soil and water pollution involving oil and water involves sampling and analyzing soil and water bodies contaminated by petroleum pollutants (such as crude oil and diesel) to assess the degree of pollution and ecological risks. Because petroleum pollutants are easily volatilized, degraded, or adsorbed, samples must be stored properly in a soil sample preservation box during testing.

[0003] In existing technologies, test tubes containing soil samples are prone to shaking and tilting inside the storage box. This is mainly because the storage box is subjected to vibration during transportation, which causes the test tubes to shake. As a result, some samples may scatter into the storage box, potentially causing cross-contamination between samples and affecting the accuracy of subsequent test results. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a soil sample anti-scattering preservation box that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A soil sample spillage prevention storage box includes a box body with a lid rotatably mounted on the top, and further includes: a top plate, fixedly connected to the box body, wherein the top plate has through holes arranged at equal intervals, and the inner bottom of the box body has a device hole aligned vertically with the through holes, wherein a buffer component is provided in the device hole; and a pressure plate, installed on the inner top of the lid, wherein the lid has a pressing part that drives the pressure plate to press downward.

[0007] Preferably, the buffer component includes a support block that is longitudinally slidably installed in the device hole, the top of the support block is provided with a groove, and an elastic element is installed between the groove and the inner bottom of the device hole.

[0008] Preferably, the top pressing part includes a slot provided on the top of the box cover, a rotating shaft is rotatably installed in the slot, a fan-shaped pressing block is fixedly connected to the outer wall of the rotating shaft, the lower end of the box cover is provided with a mounting groove, the pressing plate is longitudinally slidably installed in the mounting groove, and a spring is installed between the pressing plate and the inner top of the mounting groove.

[0009] Furthermore, a handle is fixedly installed on the rotating shaft. When the handle is swung to one side to retract or when the shaft is upright, the fan-shaped pressure block will press against the pressure plate. When the handle is swung to the other side to retract, the fan-shaped pressure block will not contact the top of the pressure plate.

[0010] Furthermore, the inner wall of the through hole is provided with an annular groove, and an annular airbag is fixedly sleeved in the annular groove. The elastic element is an elastic airbag, and the elastic element and the annular airbag are fixedly connected and communicate with each other through a connecting pipe.

[0011] Furthermore, a T-shaped block is fixedly connected to the outer wall of the housing, and a hook is fixedly connected to one end of the rotating shaft. When the handle is swung to one side to retract, the hook will hang on the T-shaped block, and when the handle is swung to the other side to retract, the hook will move away from the T-shaped block.

[0012] Furthermore, both the upper port of the through hole and the upper port of the groove are chamfered.

[0013] Preferably, a rubber pad is fixedly provided on the lower end face of the pressure plate.

[0014] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0015] 1. This utility model uses a handle to drive the rotating shaft to rotate, which causes the pressure plate to press down on the upper end of the test tube. This prevents the soil sample inside the test tube from scattering everywhere, thus preventing cross-contamination between soil samples and improving the accuracy of subsequent soil testing.

[0016] 2. Under the pressure of the top, the test tube will also drive the support block to slide towards the bottom of the device hole and compress the elastic element. The elastic element will keep the test tube elastically pressed against the lower end surface of the pressure plate, so that the test tube will not scatter the soil sample inside due to vibration.

[0017] 3. This utility model uses a connecting tube to transport the medium inside the elastic element to the annular airbag, which then expands and clamps the test tube inside the through hole, making the test tube more securely inserted into the through hole.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] Example: Referring to Figures 1-5, a soil sample spillage prevention storage box includes a box body 1 with a lid 2 rotatably mounted on the top. The lid 2 is mounted on the upper port of the box body 1 via a rotating hinge. It also includes a top plate 3, fixedly connected inside the box body 1. The top plate 3 has equally spaced through holes 4 for inserting sample tubes. The inner bottom of the box body 1 has a device hole 6 aligned vertically with the through holes 4. The device hole 6 contains a buffer component to lift the sample tubes upwards. The buffer component includes a support block 7 slidably mounted longitudinally within the device hole 6. The top of the support block 7 has a groove 8. An elastic element 9 is installed between the groove 8 and the inner bottom of the device hole 6. A pressure plate 14 for pressing down the sample tubes is installed on the inner top of the lid 2. The lid 2 has a pressing part for driving the pressure plate 14 downwards. Both the upper port of the through hole 4 and the upper port of the groove 8 have chamfers. A rubber gasket to improve sealing is fixedly mounted on the lower end face of the pressure plate 14.

[0028] Specifically, during use, the test tube containing the soil sample is inserted into the through hole 4, and the bottom of the test tube is inserted into the groove 8. Then, the box cover 2 is rotated so that the box cover 2 is on top of the box body 1. Then, the pressure plate 14 is pressed down on the upper end of the test tube by the top pressure part. Thus, the soil sample in the test tube is not allowed to scatter everywhere, preventing cross-contamination between soil samples and improving the accuracy of subsequent soil testing. Under the top pressure, the test tube will also drive the support block 7 to slide towards the bottom of the device hole 6 and compress the elastic element 9. The elastic element 9 will keep the test tube elastically pressed against the lower end surface of the pressure plate 14, so that the test tube is not allowed to scatter the soil sample inside due to vibration.

[0029] The aforementioned top pressure part includes a slot 13 provided on the top of the box cover 2. A rotating shaft 16 is rotatably installed in the slot 13. A fan-shaped pressure block 18 is fixedly connected to the outer wall of the rotating shaft 16. The lower end of the box cover 2 is provided with an installation groove 15. A pressure plate 14 is longitudinally slidably installed in the installation groove 15. A spring 5 is installed between the pressure plate 14 and the inner top of the installation groove 15.

[0030] Specifically, after closing the lid 2, the rotating shaft 16 is rotated, which in turn drives the fan-shaped pressure block 18 to rotate until the fan-shaped pressure block 18 presses against the pressure plate 14. The pressure plate 14 then presses downward against the upper end of the test tube, thus preventing the soil sample inside the test tube from scattering everywhere. When the pressure plate 14 needs to be reset, the rotating shaft 16 is rotated again until the fan-shaped pressure block 18 stops pressing against the pressure plate 14. The spring 5 then drives the pressure plate 14 to move upward and reset.

[0031] In practice, in order to prevent the shaft 16 from rotating on its own, damping components need to be installed at both ends of the shaft 16 so that there is frictional resistance between the shaft 16 and the inner wall of the slot 13, so that the shaft 16 will not rotate due to the reaction force.

[0032] A handle 17 is fixedly installed on the aforementioned rotating shaft 16. When the handle 17 is swung to one side to be stored or when it is standing up, the fan-shaped pressure block 18 will press against the pressure plate 14. When the handle 17 is swung to the other side to be stored, the fan-shaped pressure block 18 will not contact the top of the pressure plate 14.

[0033] When it is necessary to rotate the shaft 16, simply rotate the shaft 16 using the handle 17, making it more convenient to use.

[0034] The inner wall of the aforementioned through hole 4 is provided with an annular groove 10, and an annular airbag 11 is fixedly sleeved in the annular groove 10. The elastic element 9 is an elastic airbag, and the elastic element 9 and the annular airbag 11 are fixedly connected and communicated through a connecting pipe 12.

[0035] When the elastic element 9 is pressed, the internal medium is transported to the annular airbag 11 through the connecting pipe 12. The annular airbag 11 will then expand and clamp the test tube in the through hole 4, making the test tube more securely inserted into the through hole 4.

[0036] A T-shaped block 20 is fixedly connected to the outer wall of the aforementioned box 1, and a hook 19 is fixedly connected to one end of the rotating shaft 16. When the handle 17 is swung to one side to retract, the hook 19 will hang on the T-shaped block 20. When the handle 17 is swung to the other side to retract, the hook 19 will move away from the T-shaped block 20.

[0037] When the rotating shaft 16 rotates, it also drives the hook 19 to rotate. When the pressure plate 14 is in the downward state, the hook 19 will hook onto the T-shaped block 20, thereby achieving the automatic locking of the lid 2. When the fan-shaped pressure block 18 does not press against the pressure plate 14, the pressure plate 14 will move upward and reset under the action of the spring 5, and the hook 19 will not hook onto the T-shaped block 20, thus simultaneously completing the unlocking of the lid 2. Since the handle 17 is installed on the rotating shaft 16, when the handle 17 is in the vertical state or retracted to one side, the lid 2 will be automatically locked, and the pressure plate 14 will also be automatically pressed down. When the handle 17 is in the retracted state on the other side, the pressure plate 14 will not press down, and the lid 2 will be unlocked. It is more convenient and less strenuous to use. In other words, the linkage design of the handle 17 and the fan-shaped pressure block 18 makes the use of the entire device more convenient and flexible, and the structure is ingenious.

[0038] In this soil sample spillage prevention storage box, when in use, insert the test tube containing the soil sample into the through hole 4, and insert the bottom of the test tube into the groove 8. Then rotate the box cover 2 so that the box cover 2 is on top of the box body 1. Then rotate the handle 17 so that the handle 17 drives the rotating shaft 16 to rotate. The rotating shaft 16 drives the fan-shaped pressure block 18 to rotate until the fan-shaped pressure block 18 presses against the pressure plate 14. The pressure plate 14 then presses down on the upper end of the test tube. Thus, the soil sample in the test tube should not scatter everywhere, preventing cross-contamination between soil samples and improving the accuracy of subsequent soil testing. Under the pressure, the test tube will also drive the support block 7 to slide towards the bottom of the device hole 6 and compress the elastic element 9. The elastic element 9 will keep the test tube elastically pressed against the lower end surface of the pressure plate 14, so that the test tube should not scatter the soil sample inside due to vibration.
