DETAILED DESCRIPTION

[0020] The utility model is now described in further detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0021] Please refer to Figure 1-6 A rapid detection kit for pesticide residues comprises a kit 1 and a flip cover 2 at a port, the kit 1 is provided with an inner box body 3, the inner box body 3 is provided with a plurality of vertically arranged reagent tubes 7, the ends of the reagent tubes 7 are provided with sealed end caps 72, and telescopic mechanisms are provided on both sides of the inner box body 3, and the inner box body 3 can slide back and forth in the kit 1 through the telescopic mechanism; when in use, the pesticide residue liquid to be detected is stored in the reagent tube 7, and then the port is covered by the end cover 72 to prevent the entry of debris and avoid spillage; after storage, the flip cover 2 is covered, and at this time, the inner box body 3 can slide unidirectionally through the telescopic mechanism, eliminating external forces on both sides, and preventing the internal pesticide residue liquid from shaking significantly and causing spillage.

[0022] In this embodiment, two parallel partitions 31 are provided in the inner box body 3, and the reagent tube 7 is vertically provided through the two partitions 31. An electric heating wire 71 is provided between the two partitions 31, and the electric heating wire 71 is in contact with the outer wall of the reagent tube 7. The reagent box 1 is provided with a power supply assembly 4, and the power supply assembly includes a battery assembly and a switch assembly. The power supply assembly 4 is connected to the electric heating wire 71 through a wire, and the electric heating wire 71 is set in a spring-shaped spiral. After the power supply assembly 4 is running, the electric heating wire 71 generates heat, and the heating temperature is 18-26°C, so that the pesticide residue liquid in the reagent tube 7 maintains a certain temperature, thereby avoiding large errors due to temperature during measurement.

[0023] Specifically, the top wall of the end cap 72 is provided with an integral rubber layer 721, and a plurality of slits 722 are provided in the rubber layer 721. The plurality of slits 722 are arranged in an array along the axis of the end cap 72. A sealing diaphragm 723 is provided in the end cap 72, and the end cap 72 is plug-in connected to the reagent tube 7.

[0024] Since the top wall of the end cover 72 is a rubber layer 721, and the rubber layer 721 is divided by a plurality of slits 722, when a foreign object is inserted into the slit 722, the rubber layer 721 can be deformed. At this time, the rubber dropper can be smoothly inserted and pulled out at the center of the circle of the end cover 72. When in use, the rubber dropper is inserted into the end cover and extended into the reagent tube 7, and then the internal pesticide residue liquid is sucked out for detection, so as to avoid the internal liquid from being exposed and volatilized, and at the same time, foreign matter is prevented from entering the liquid to affect the detection accuracy. After the rubber dropper is pulled out, the rubber on both sides of the slit returns to its original position to block foreign objects.

[0025] In addition, when the rubber-tipped dropper extends into the reagent tube 7, it will puncture the sealing diaphragm 723. The establishment of the sealing diaphragm 723 can isolate the internal liquid from the outside to prevent shaking and spilling. The sealing diaphragm 723 has the same principle as the oral liquid port in the prior art, and will not be elaborated here.

[0026] Furthermore, the telescopic mechanism includes a first U-shaped rod 5 and a second U-shaped rod 6, the first U-shaped rod 5 and the second U-shaped rod 6 are opposite and plug-in connected, that is, the two extended ends of the first U-shaped rod 5 are inserted into the two extended ends of the second U-shaped rod 6, wherein the ends of the second U-shaped rod 6 are provided with springs, and the elastic plug-in and pull-out of the first U-shaped rod 5 and the second U-shaped rod 6 can be understood as two damping rods; the first U-shaped rod 5 is fixed to the outer wall of the inner box body 3, and the second U-shaped rod 6 is fixed to the inner wall of the reagent box 1, and in addition, the bottom of the inner box body 3 and the reagent box 1 are connected to the bottom of the inner box body 3. The inner bottom surface of the reagent box 1 is provided with upper and lower corresponding slideways 32, and a rolling ball 33 is provided between the two slideways 32, and the circumference of the rolling ball 33 always contacts the two upper and lower slideways 32; when the reagent box is subjected to external force in the front and rear directions during use, the first U-shaped rod 5 and the second U-shaped rod 6 are further extended and plugged in, and the rolling ball 33 at the bottom will roll along the slideway for a distance. When the external force is eliminated, the spring in the second U-shaped rod 6 pushes the first U-shaped rod 5 back to its original position, thereby facilitating the elimination of external force in the front and rear directions and avoiding damage to the internal reagent tubes.

[0027] 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 therefrom are still within the scope of protection of the invention of the utility model.
