After fixing, the sealing threaded block 6 is unscrewed, and the test tube storing the soil sample is placed in the placement groove 3, and then the sealing threaded block 6 is screwed in to fix the placement groove 3. By unscrewing the sealing threaded block 6, a single placement groove 3 is opened, and then the test tube is placed in the placement groove 3. The structural design of the placement groove 3 is sealed by the sealing threaded block 6, which realizes the function of effectively avoiding excessive heat exchange when the test tube is placed. It effectively solves the problem that each time a soil sample is placed in the storage box, the storage box cover must be opened and the soil sample is stored, and opening the box cover easily causes a large temperature change in the storage box, which affects the storage of the soil sample.

[0028] Reference Figure 4As shown, a pushing block 7 is slidably connected to the bottom of the placement groove 3; a spring is fixedly connected between the bottom of the pushing block 7 and the bottom side wall of the placement groove 3; during operation, after the test tube is placed in the placement groove 3, the sealing thread block 6 is screwed into the placement groove 3, and the sealing thread block 6 pushes the test tube, so that the test tube pushes the pushing block 7, and then the spring pushes the pushing block 7, which can make the pressure between the test tube and the sealing thread block 6 and the pushing block 7 greater, and the friction between the test tube and the sealing thread block 6 and the pushing block 7 greater, so that the test tube can be less shaken when placed in the placement groove 3, and the placement of the test tube is more stable.

[0029] Reference Figures 4 to 5 As shown, the push block 7 is internally rotatably connected with a driven seat 8; the driven seat 8 is arranged at a position corresponding to the top of the push block 7; during operation, when the sealing thread block 6 is screwed into the interior of the placement groove 3, when the top of the test tube contacts the sealing thread block 6, the rotation of the sealing thread block 6 will drive the test tube to rotate together, and when the test tube contacts the pushing block 7 at the bottom, the driven seat 8 is connected to the internal rotation of the pushing block 7, so that the driven seat 8 can rotate with the test tube during the rotation of the test tube, thereby effectively avoiding excessive friction between the test tube and the pushing block 7, resulting in excessive wear between the test tube and the pushing block 7.

[0030] Reference Figures 5 and 6 As shown, a positioning block 9 is fixed to the bottom of the driven seat 8; the positioning block 9 is rotatably connected to the internal position of the pushing block 7; during operation, when the driven seat 8 rotates inside the pushing block 7, by arranging the driven seat 8 at the bottom of the driven seat 8 and limiting the rotation of the positioning block 9 by the pushing block 7, the driven seat 8 is less likely to tilt during the rotation process, making the rotation of the driven seat 8 more stable.

[0031] Reference Figures 5 and 6 As shown, a plurality of anti-wear balls 10 are arranged between the pushing block 7 and the positioning block 9; the side walls of the anti-wear balls 10 are in contact with the side walls of the pushing block 7 and the positioning block 9; during operation, when the positioning block 9 rotates inside the pushing block 7, by arranging the anti-wear balls 10 between the pushing block 7 and the positioning block 9, the sliding friction between the pushing block 7 and the positioning block 9 can be converted into rolling friction, so that the friction force between the pushing block 7 and the positioning block 9 is smaller, thereby reducing the wear between the pushing block 7 and the positioning block 9.

[0032] Reference Figure 7As shown, the interior of the fixing bolt 5 is slidably connected with a sliding plate 11; a spring is fixedly connected between the top of the sliding plate 11 and the inner side wall of the fixing bolt 5; a connecting rod 12 is fixedly connected to the bottom of the sliding plate 11; a contact block 13 is fixedly connected to the bottom end of the connecting rod 12; during operation, when the storage rack 2 is fixed by the fixing bolt 5, the sliding plate 11 is pushed by the spring, and then the sliding plate 11 pushes the connecting rod 12 and the contact block 13, which can make the pressure between the fixing bolt 5 and the storage rack 2 and the threaded holes of the support plate 4 greater, so that the friction between the fixing bolt 5 and the storage rack 2 and the support plate 4 can be greater, so that the fixing effect of the fixing bolt 5 on the storage rack 2 is better.

[0033] Reference Figure 4 As shown, a plurality of guide pulleys 14 are fixedly connected to the interior of the placement slot 3; the guide pulleys 14 are regularly arranged in a circular array inside the placement slot 3; during operation, when the test tube is placed inside the placement slot 3, by arranging the guide pulleys 14 on the side wall of the placement slot 3, the friction between the test tube and the placement slot 3 can be reduced, so that during the process of placing the test tube inside the placement slot 3, there is less wear between the test tube and the side wall of the placement slot 3.

[0034] Reference Figure 8 As shown, a first vacuum groove 15 is opened inside the storage rack 2; a second vacuum groove 16 is opened inside the sealing thread block 6; during operation, by opening the first vacuum groove 15 inside the storage rack 2 and the second vacuum groove 16 inside the sealing thread block 6, less heat exchange between the storage box 1 and the outside world can be achieved, so that the thermal insulation effect of the storage box 1 is better. At the same time, by opening the first vacuum groove 15 inside the storage rack 2 and the second vacuum groove 16 inside the sealing thread block 6, the weight of the storage rack 2 and the sealing thread block 6 can be made lighter, so that the storage box 1 is more convenient to carry.

[0035] During operation, when it is necessary to store the soil sample, ice cubes, dry ice and other coolants can be placed in the internal position of the storage box 1, and the storage rack 2 cover can be set on the top of the support plate 4. Then, the storage rack 2 can be fixed to the inside of the storage box 1 by the fixing bolts 5. After the fixing is completed, the sealing threaded block 6 is unscrewed, and the test tube storing the soil sample is placed in the placement groove 3, and then the sealing threaded block 6 is screwed in to fix the placement groove 3. By unscrewing the sealing threaded block 6, a single placement groove 3 is opened, and then the test tube is placed in the placement groove 3. The structural design of the placement groove 3 is sealed by the sealing threaded block 6, which realizes the function of effectively avoiding excessive heat exchange when the test tube is placed. It effectively solves the problem that each time a soil sample is placed in the storage box, the storage box cover must be opened and the soil sample is stored. Opening the box cover easily causes a large temperature change in the storage box, which affects the storage of the soil sample.

[0036] After the test tube is placed in the placement groove 3, when the sealing thread block 6 is screwed into the placement groove 3, the sealing thread block 6 will push the test tube, so that the test tube pushes the pushing block 7, and then the spring pushes the pushing block 7, which can make the pressure between the test tube and the sealing thread block 6 and the pushing block 7 greater, and the friction between the test tube and the sealing thread block 6 and the pushing block 7 greater, so that the test tube will shake less when placed in the placement groove 3, making the placement of the test tube more stable.

[0037] When the sealing thread block 6 is screwed into the placement groove 3, the top of the test tube contacts the sealing thread block 6, and the rotation of the sealing thread block 6 will drive the test tube to rotate together. When the test tube contacts the pushing block 7 at the bottom, the driven seat 8 is connected by rotating inside the pushing block 7, so that the driven seat 8 can rotate with the test tube during the rotation of the test tube, thereby effectively avoiding excessive friction between the test tube and the pushing block 7, which may cause excessive wear between the test tube and the pushing block 7.

[0038] When the driven seat 8 rotates inside the pushing block 7, by arranging the driven seat 8 at the bottom of the driven seat 8 and limiting the rotation of the positioning block 9 by the pushing block 7, the driven seat 8 is less likely to tilt during the rotation, making the rotation of the driven seat 8 more stable.

[0039] When the positioning block 9 rotates inside the pushing block 7, by arranging the anti-wear balls 10 between the pushing block 7 and the positioning block 9, the sliding friction between the pushing block 7 and the positioning block 9 can be changed into rolling friction, so that the friction force between the pushing block 7 and the positioning block 9 is smaller, thereby reducing the wear between the pushing block 7 and the positioning block 9.

[0040] When the storage rack 2 is fixed by the fixing bolt 5, the sliding plate 11 is pushed by the spring, and then the sliding plate 11 pushes the connecting rod 12 and the contact block 13, which can make the pressure between the fixing bolt 5 and the threaded holes of the storage rack 2 and the support plate 4 greater, thereby making the friction between the fixing bolt 5 and the storage rack 2 and the support plate 4 greater, so that the fixing effect of the fixing bolt 5 on the storage rack 2 is better.

[0041] When the test tube is placed inside the placement groove 3, by setting a guide pulley 14 on the side wall of the placement groove 3, the friction between the test tube and the placement groove 3 can be reduced, so that the test tube and the side wall of the placement groove 3 will be less worn during the process of placing the test tube inside the placement groove 3.

[0042] By opening a first vacuum groove 15 inside the storage rack 2 and a second vacuum groove 16 inside the sealing thread block 6, heat exchange between the storage box 1 and the outside world can be reduced, so that the thermal insulation effect of the storage box 1 is better. At the same time, by opening a first vacuum groove 15 inside the storage rack 2 and a second vacuum groove 16 inside the sealing thread block 6, the weight of the storage rack 2 and the sealing thread block 6 can be made lighter, so that the storage box 1 is more convenient to carry.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
