Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3As shown in the figure, this embodiment specifically discloses a soil fresh sample preservation device for soil microbial determination, including a preservation box 1. Protective components 2 are provided on both sides of the preservation box 1. Each protective component 2 includes an L-shaped plate 21, rubber blocks 22, and damping shafts 23. L-shaped plates 21 are provided on both sides of the preservation box 1. The inner walls of the L-shaped plates 21 are fixedly connected to the preservation box 1 by several evenly distributed rubber blocks 22. Several evenly distributed damping shafts 23 are provided between two rubber blocks 22. One end of each damping shaft 23 is fixedly connected to an L-shaped plate 21, and the other end is fixedly connected to the preservation box 1. The set of springs 23 and 24 has one end fixedly connected to the L-shaped plate 21 and the other end fixedly connected to the storage box 1. When the device is transported or is subjected to a collision, the rubber block 22, spring 24 and damping shaft 23 can buffer and reduce the shock of the storage box 1, so as to stabilize the fresh soil sample tube during transportation and avoid severe vibration or bumps during the transportation of fresh soil samples, which could cause damage to the fresh soil sample tube in the storage device. This further improves the stability of the fresh soil sample storage device. The L-shaped plate 21 can also protect the storage box 1.

[0021] The top surface of the storage box 1 is provided with a box cover 3. The box cover 3 is connected to the storage box 1 by a connector 4. The connector 4 includes a U-shaped base 41, a crossbar 42, and a fixing plate 43. The fixing plate 43 is fixedly installed on both sides of the box cover 3. The U-shaped base 41 is fixedly installed on both sides of the top of the storage box 1. The crossbar 42 is rotatably installed inside the U-shaped base 41. An L-shaped frame 44 is fixedly installed at one end of the crossbar 42. The L-shaped frame 44 mates with the top surface of the fixing plate 43. A screw hole 45 is opened at the upper end of the L-shaped frame 44. A limiting hole 46 is opened on the top surface of the fixing plate 43. A bolt 47 is threaded into the screw hole 45. The lower end of the bolt 47 is inserted into the corresponding limiting hole. Inside hole 46, fasten the lid 3 to the storage box 1. Rotate the crossbar 42, which drives the L-shaped frame 44 to rotate upward, so that the L-shaped frame 44 mates with the top surface of the fixing plate 43. Rotate the bolt 47 so that the lower end of the bolt 47 is inserted into the corresponding limiting hole 46, which can limit the fixing plate 43, thereby limiting the lid 3 and fixing the lid 3 to the storage box 1. When it is necessary to open the lid 3, rotate the bolt 47 so that the end of the bolt 47 moves out of the limiting hole 46. Rotate the L-shaped frame 44 downward, and the L-shaped frame 44 and the fixing plate 43 no longer mate, so that the lid 3 can be opened.

[0022] A fixing block 5 is installed inside the storage box 1. Several evenly distributed fixing components 6 are installed above the fixing block 5. The fixing components 6 include a sleeve 61, a clamping block 62, and a push rod 63. The sleeve 61 is fixedly installed on the top surface of the fixing block 5 and corresponds to the placement groove 8. Through holes 64 are opened on both sides of the sleeve 61. The push rod 63 is movably installed in the through holes 64. The clamping block 62 is fixedly installed at one end of the push rod 63. The side of the two clamping blocks 62 that are close to each other is an inclined surface. The fresh soil sample tube cooperates with the clamping block 62. The other end of the push rod 63 is rotatably connected to the inclined rod 6. 5. The lower end of the inclined rod 65 is rotatably connected to the support 66, and the support 66 is fixedly connected to the sleeve 61. The upper end of the inclined rod 65 is fixedly connected to the sleeve 61 through the tension spring 67. The soil fresh sample tube is inserted into the sleeve 61, and the lower end of the soil fresh sample tube passes through the corresponding two clamping blocks 62. The lower end of the soil fresh sample tube is inserted into the placement groove 8. Under the tension spring 67, the two clamping blocks 62 further tighten the soil fresh sample tube to prevent the soil fresh sample tube from being placed unstable and to accommodate soil fresh sample tubes of different sizes.

[0023] The bottom surface of the box cover 3 is provided with several evenly distributed pressing mechanisms 7. The pressing mechanism 7 includes an inner cover 71, a push block 72, and a thrust spring 73. The bottom surface inside the box cover 3 is provided with several evenly distributed limiting grooves 74. The push block 72 is slidably arranged in the limiting groove 74. The upper end of the push block 72 is fixedly connected to the inner wall of the limiting groove 74 by the thrust spring 73. The lower end of the push block 72 is fixedly installed with the inner cover 71. Fixing spring pieces 75 are provided on both sides inside the inner cover 71. The upper end of the fresh soil sample tube is inserted into the inner cover 71 and cooperates with the fixing spring pieces 75. When the box cover 3 is closed, the push block 72 is pushed by the thrust spring 73 to move the inner cover 71 downward, so that the upper end of the fresh soil sample tube is inserted into the inner cover 71 and cooperates with the fixing spring pieces 75. This can seal the fresh soil sample tube and prevent the soil inside the fresh soil sample tube from splashing out during movement, thus avoiding contamination of other soil.

[0024] The top surface of the fixing block 5 has several evenly distributed placement slots 8. The placement slots 8 and the fixing components 6 are all corresponding to the pressing mechanism 7. The bottom surface inside the storage box 1 is provided with a cooler body 9. The bottom surface of the storage box 1 is provided with several evenly distributed heat dissipation mesh holes 10. The bottom surface of the fixing block 5 has several evenly distributed ventilation holes 11.

[0025] Working principle:

[0026] Insert the fresh soil sample tube into the sleeve 61. The lower end of the fresh soil sample tube passes through the two corresponding clamping blocks 62 and is inserted into the placement groove 8. Under the tension and rebound action of the tension spring 67, the two clamping blocks 62 further tighten the fresh soil sample tube, preventing it from being unstable and accommodating soil sample tubes of different sizes. Fasten the box cover 3 to the storage box 1. Rotate the crossbar 42, which drives the L-shaped frame 44 to rotate upward, so that the L-shaped frame 44 mates with the top surface of the fixing plate 43. Rotate the bolt 47 so that the lower end of the bolt 47 is inserted into the corresponding limiting hole 46, which can limit the fixing plate 43 and thus limit the box cover 3, fixing the box cover 3 to the storage box 1. When it is necessary to open the box cover 3, rotate the bolt 47 so that the end of the bolt 47 moves out of the limiting hole 46 and rotate the L-shaped frame downward. 44. When the L-shaped frame 44 and the fixing plate 43 are no longer engaged, the box cover 3 can be opened and closed. Under the action of the thrust spring 73, the push block 72 is pushed to move the inner cover 71 downward, so that the upper end of the soil fresh sample tube is inserted into the inner cover 71 and engages with the fixing spring piece 75. This can seal the soil fresh sample tube and prevent the soil inside the soil fresh sample tube from splashing out during movement, thus preventing contamination of other soil. When the device is transported or when the device is impacted, the rubber block 22, spring 24 and damping shaft 23 can buffer and reduce shock for the storage box 1, so as to stabilize the soil fresh sample tube during transportation and prevent severe vibration or bumps during the transportation of soil fresh samples, which could cause damage to the soil fresh sample tube in the storage device. This further improves the stability of the soil fresh sample storage device. The L-shaped plate 21 can protect the storage box 1.
