[0027] like Figures 1-4As shown in the figure, an embodiment of this utility model proposes a sample storage device for pesticide residue detection, including two support plates 1. A placement tray 2 is fixedly connected to the top of the support plate 1. Multiple placement slots 3 are arrayed on the top of the placement tray 2. A sample tube 7 is movably fitted inside the placement slot 3. A tube cover 8 is fitted on the top of the sample tube 7. An insertion slot 4 is opened at the center of the top of the placement tray 2. A ring-shaped limiting slot 5 is opened at the bottom of the insertion slot 4. A sealing ring 6 is fixedly connected to the top of the placement tray 2. A cover plate 9 is provided above the sealing ring 6. A locking component is rotatably provided on the cover plate 9. The locking component is used to lock the cover plate 9 and the placement tray 2 together.

[0028] like Figure 3 As shown, the locking assembly includes a rotating rod 11 that moves through the cover plate 9. The bottom end of the rotating rod 11 is fixedly connected to a limiting rod 12. Two limiting rings 13 located on the upper and lower sides of the cover plate 9 are fixedly sleeved on the outside of the rotating rod 11. A top plate 14 is fixedly connected to the top end of the rotating rod 11. The limiting rings 13 lock the rotating rod 11 on the cover plate 9, so that the rotating rod 11 can only rotate horizontally.

[0029] like Figure 3 As shown, the cover plate 9 has a rotating hole, and the rotating rod 11 moves through the rotating hole and rotates within the rotating hole.

[0030] like Figure 3 As shown, the top of the cover plate 9 is provided with two alignment protrusions 10, and the outside of the placement plate 2 is provided with a handle 15, which drives the rotating rod 11 to rotate.

[0031] like Figure 3 The placement groove 3 is provided with a buffer sponge inside, and the top of the sealing ring 6 is provided with a sealing gasket, and the sealing gasket is in close contact with the cover plate 9, which is conducive to the sealing contact between the cover plate 9 and the placement tray 2.

[0032] like Figure 4 As shown, the bottom of the support plate 1 is provided with an anti-slip pad, which helps the entire device to be more stable when placed.

[0033] Working principle: The sample cylinder 7 containing the sample is tightly covered with the cylinder cap 8, and then the sample cylinder 7 is placed in the placement slot 3. The cover plate 9 is then placed on the placement tray 2. At this time, the rotation point of the alignment protrusion 10 and the handle 15 are on the same vertical plane. Thus, the rotating rod 11 and the limiting rod 12 are inserted into the insertion slot 4. Then, the handle 14 is rotated, and the handle 14 drives the rotating rod 11 and the limiting rod 12 to rotate. Thus, the limiting rod 12 rotates 90 degrees in the limiting slot 5, thereby making the limiting rod 12 and the insertion slot 4 misaligned for limiting. The operator can then carry the entire device through the handle 15. Multiple devices can also be stacked. When stacked, the rotating rod 11 is between the two support plates 1.
