Description

Technical Field

[0001] The utility model relates to the technical field of pesticide residue detection, in particular to a pesticide residue detection card structure. Background Art

[0002] Pesticide residues refer to the trace amounts of pesticide precursors, toxic metabolites, degradation products and impurities that remain in organisms, harvests, soil, water and the atmosphere after a period of time after pesticide use. Some of the pesticides applied to crops adhere to the crops, while others are scattered in the soil, atmosphere and water. Some of the pesticides remaining in the environment will be absorbed by plants. Pesticide residues directly reach humans and animals through plant fruits, water and the atmosphere, or are ultimately passed on to humans and animals through the environment and the food chain. The problem of pesticide residues is becoming increasingly serious with the mass production and widespread use of pesticides.

[0003] There are many methods for detecting pesticide residues. Among them, the enzyme inhibition rate method in the biochemical determination method using the pesticide residue detection card has become one of the mainstream technologies for on-site rapid qualitative screening of organophosphorus and carbamate pesticide residues in fruits and vegetables due to its characteristics of rapidity, sensitivity, ease of operation and low cost. It has been increasingly widely used.

[0004] In the prior art, during the use of conventional pesticide residue detection cards, the sample addition holes and the through holes are directly exposed, resulting in direct contact between the internal test paper and the outside. Before carrying or using, there is a problem of contaminating the test paper. In addition, during use, the sample solution and the test paper are unevenly distributed and cannot be fully contacted, resulting in low detection efficiency and reduced accuracy of the detection effect.

[0021] Specifically, the round box 1 includes a bottom box 101 and a sealing cover 102 , and the sealing cover 102 is threadedly mounted on the upper surface of the bottom box 101 .

[0022] In this embodiment, the bottom box 101 and the sealing cover 102 are connected to each other by nuts, which is convenient for disassembly of the round box 1, that is, convenient for disassembly and assembly of the detection mechanism 8.

[0023] Specifically, a rubber damping sleeve 10 is fixedly mounted on the upper side wall of the round box 1 corresponding to the cylinder 5 .

[0024] In this embodiment, the rubber damping sleeve 10 prevents the cylinder 5 from rotating randomly.

[0025] Specifically, the snap mechanism 6 includes a mounting hole 601, a clamping block 602 and a clamping groove 603. A mounting hole 601 is opened on the top plate 7 at a position corresponding to the cylinder 5. Clamping blocks 602 are evenly arranged along the circumferential direction on the inner wall of the mounting hole 601. A clamping groove 603 is opened on the outer surface of the cylinder 5 corresponding to the clamping block 602, and the clamping block 602 is clamped in the clamping groove 603.

[0026] In this embodiment, the clamping block 602 on the inner wall of the mounting hole 601 is buckled in the clamping groove 603, so that the top plate 7 is connected to the cylinder 5, and the cylinder 5 drives the top plate 7 to rotate.

[0027] Specifically, the detection mechanism 8 includes a water absorbing layer 801 , a display layer 802 and an isolation plate 803 . The water absorbing layer 801 and the display layer 802 are fixedly installed in sequence from top to bottom, and the water absorbing layer 801 and the display layer 802 are located on the left and right sides of the cylinder 5 and the isolation plate 803 is embedded therein.

[0032] In summary, the pesticide residue detection card structure can isolate the detection mechanism 8 from the outside before detection, effectively preventing the detection mechanism 8 from being contaminated or damaged, making it safer to use. At the same time, it adds a reciprocating rotation function to enable the sample solution to quickly and fully contact with the detection mechanism 8, thereby improving the reaction speed and making the detection results faster and more accurate.
