The bottom placement frame 9 that exceeds the sample retention date is removed and cleaned, and then filled in from the top. It is always taken out from the fixed position at the bottom to avoid affecting the sample extraction efficiency and improve the practicality of the equipment. A slidable and adjustable adjustment component 14 is arranged inside the placement component 11, which is adapted and adjusted according to the size of the placed sample to improve the space utilization rate.

[0031] Embodiment 2:

[0032] As Figure 1 shown, a sample retention device for pesticide residue detection disclosed in Embodiment 2 of the present utility model has basically the same structure as that in Embodiment 1, and the difference lies in that the opening and closing component 4 includes a door panel 401, and the door panel 401 is arranged on the left and right sides at the front end of the sample retention box body 1, and a handle 402 is arranged at the front end of the door panel 401;

[0033] The door panel 401 is connected to the side of the sample retention box body 1 through a hinge for easy rotation and opening and closing. A sealing strip is arranged inside the door panel 401 to improve the sealing performance of the equipment, and the setting of the handle 402 is convenient for opening and closing adjustment.

[0034] Embodiment 3:

[0035] As Figure 2 and Figure 3 shown, a sample retention device for pesticide residue detection disclosed in Embodiment 3 of the present utility model has basically the same structure as that in Embodiment 2, and the difference lies in that a bottom placement frame 9 is arranged at the top end of the moving-out track plate 6, a middle placement frame 10 is arranged at the top end of the bottom placement frame 9, a placement component 11 is arranged at the top end of the middle placement frame 10, and limiting components 12 are arranged on both the left and right sides of the placement component 11. The placement component 11 includes a top placement frame 1101, and the top placement frame 1101 is arranged at the top end of the middle placement frame 10. A pulling block 1102 is arranged at the front end of the top placement frame 1101, and limiting top blocks 1103 are arranged at the four corners of the upper and lower ends of the top placement frame 1101. The limiting component 12 includes a clamping block 1201, and the clamping block 1201 is installed on both the left and right sides of the top placement frame 1101. A limiting pulley 1202 is arranged on the outside of the clamping block 1201. Telescopic blocking components 15 are arranged at the bottom of the left and right ends inside the sample retention box body 1, and the telescopic blocking components 15 include telescopic rods 1501. The telescopic rods 1501 are arranged at the bottom of the left and right ends inside the sample retention box body 1, and a blocking plate 1502 is installed inside the telescopic rods 1501;

[0036] The internal structures of the bottom placement frame 9, the middle placement frame 10, and the placement component 11 are the same, and there are multiple middle placement frames 10 arranged in the middle. The number of middle placement frames 10 is selected according to the retention period of the samples. When the samples reach the extraction time, the adapted limit top block 1103 can be stuck inside the removal track plate 6. Then, at this time, the limit pulleys 1202 on both sides are separated from the bottom end of the limit clamping plate 5, and the telescopic rod 1501 retracts inward, enabling the blocking plate 1502 to support at the bottom of the middle placement frame 10 in the penultimate layer, facilitating the removal of the bottom placement frame 9 at the bottom. After the removal, the blocking plate 1502 is released, allowing the middle placement frame 10 and the placement component 11 to descend synchronously. After the removed bottom placement frame 9 is cleaned, the limit pulleys 1202 on both sides can be inserted into the top insertion track plate 7, and then, after being limited by the limit baffle 8, it is moved into the top end of the limit clamping plate 5. Through such adjustment, the removal operation can be cycled. When the sampling time arrives, the bottommost placement frame is always taken, avoiding taking the wrong one or wasting time in searching, and improving the practicality of the equipment.

[0037] Embodiment 4:

[0038] As Figure 4 shown, a retention device for pesticide residue detection disclosed in Embodiment 3 of the present utility model has a structure basically the same as that in Embodiment 3, except that fixed strips 13 are provided on the front and rear inner walls of the top placement frame 1101, and an adjustment component 14 is provided on the outer side of the fixed strips 13. The adjustment component 14 includes an adjustment slide plate 1401, and the adjustment slide plate 1401 is arranged on the outer side of the fixed strip 13, and a note slot 1402 is provided at the top end of the adjustment slide plate 1401;

[0039] The fixed strips 13 are located at the front and rear ends inside the top placement frame 1101. Then, the adjustment slide plate 1401 can slide outside the fixed strip 13. Through the movement adjustment of multiple adjustment slide plates 1401, the internal space of the top placement frame 1101 can be adaptively adjusted to facilitate the fixation of sample placement vessels of different sizes. Moreover, a note slot 1402 is provided at the top end of the adjustment slide plate 1401 to place the detailed information of the samples, reducing the damage to the label information caused by the humid internal environment of the retention box body 1.

[0040] The specific solution of this scheme is as follows: The sample box for pesticide residue detection (1) is used to store and retain samples. The door panel 401 is connected to the side of the sample box 1 through a hinge, which is convenient for rotation and opening / closing, and is also convenient for sealing the internal environment. The internal structures of the bottom placement frame 9, the middle placement frame 10, and the placement component 11 stacked inside the sample box 1 are the same, and there are multiple middle placement frames 10 arranged in the middle. The number of middle placement frames 10 is selected according to the retention period. When the sample reaches the removal time, the adapted limit top block 1103 can be stuck inside the removal track plate 6. Then, at this time, the limit pulleys 1202 on both sides are disengaged from the bottom of the limit clamping plate 5, and the telescopic rod 1501 retracts inward, so that the blocking plate 1502 supports at the bottom of the middle placement frame 10 in the penultimate layer, facilitating the removal of the bottom placement frame 9 at the bottom. After the removal, the blocking plate 1502 is released, so that the middle placement frame 10 and the placement component 11 descend synchronously. After the removed bottom placement frame 9 is cleaned, the limit pulleys 1202 on both sides can be inserted into the top insertion track plate 7, and then after being limited by the limit baffle 8, they are moved to the top of the limit clamping plate 5. Through such adjustment, the removal operation can be cycled. When the sampling time arrives, always take the bottommost placement frame to avoid taking the wrong one or wasting time in searching. The fixing strip 13 is located at the front and rear ends inside the top placement frame 1101. Then, the adjustment slide plate 1401 can slide outside the fixing strip 13. Through the movement and adjustment of multiple adjustment slide plates 1401, the internal space of the top placement frame 1101 can be adaptively adjusted to facilitate the fixation of sample placement vessels of different sizes. And a note slot 1402 is provided at the top of the adjustment slide plate 1401 to place the detailed information of the sample, reducing the damage to the label information caused by the humidity of the internal environment of the sample box 1.
