Description

Technical Field

[0001] The utility model relates to the technical field of omethoate detection, in particular to a rapid detection kit for omethoate. Background Art

[0002] Omethoate is an organophosphorus insecticide, also known as omethoate phosphorus or omethoate phosphate. It is a broad-spectrum insecticide commonly used in agriculture to control various pests such as aphids, beetles, mites, etc., as well as certain disease vectors such as mosquitoes and flies.

[0003] However, in life when it is necessary to detect omethoate residues, first, the epidermis of the vegetable or fruit sample to be tested is peeled and added to a reagent tube. Then, a fixed volume of diluent is added to the reagent tube to ensure thorough mixing. Next, the sample is thoroughly mixed by manually inverting and shaking to ensure that the residues in the sample are evenly distributed. After mixing, the obtained sample solution will be used for subsequent detection steps. Before dropping the sample solution into the detection hole of the test card, it is necessary to check the mixing effect to ensure accurate detection results. However, it should be noted that the effect of manual mixing is not so uniform, so additional operations may be required to ensure thorough mixing. In addition, during the manual mixing process, the staff needs to repeatedly invert and shake to ensure that the chemicals in the sample are fully dissolved and dispersed. Long-term manual mixing will increase the burden on the staff.

[0004] Therefore, we provide a rapid detection kit for omethoate. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rapid detection kit for omethoate to solve the problems raised in the above background art.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. For this omethoate rapid detection kit, through the setting of the clamping member, manually rotating the threaded rod can drive the relative movement between the sub-clamping ring and the main clamping ring, thereby opening the opening of the clamping member. Then, place the reagent tube inside the main clamping ring and the sub-clamping ring, and rotate the threaded rod in the reverse direction until the reagent tube is firmly clamped. Taking the reagent tube through the clamping member effectively reduces the burden on the staff holding the reagent tube.

[0015] 2.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 As shown, the present utility model provides an implementation manner: an omethoate rapid detection kit, including a fixed plate 1, a detection card placement box 2, a support column 4 and a clamping member 5. A detection card placement box 2 is fixedly installed on one side of the upper end of the fixed plate 1, a C-shaped frame 3 is fixedly installed on the other side of the upper end of the fixed plate 1, a support column 4 is rotatably installed inside the C-shaped frame 3, and a clamping member 5 for clamping a reagent tube is rotatably installed on one side of the upper end of the support column 4.

[0023] Further, a slot 21 for placing a test card is formed on one side of the test card placement box 2. A plurality of limiting blocks 211 are fixedly installed at the bottom of the slot 21. Through the limiting blocks 211, the test card card slot can be installed inside the slot 21. A through hole 22 is formed through one side of the upper surface of the test card placement box 2, and the position of the through hole 22 coincides with the test hole of the test card. A display slot 23 is formed through the other side of the upper surface of the test card placement box 2, and a transparent acrylic plate is installed at the upper end of the display slot 23.

[0024] Further, damping rotating shafts 41 are welded to both sides of the lower end of the support column 4, and the damping rotating shafts 41 are rotatably installed inside the C-shaped frame 3. During use, the support column 4 can be opened through the damping rotating shafts 41. When not in use, the support column 4 can be folded through the damping rotating shafts 41.

[0025] Further, an installation cavity 42 is formed at the upper end of the support column 4. A first rotation hole 421 is formed through the side surface of the installation cavity 42. A end cover 43 is installed in a card slot on the other side of the installation cavity 42. A second rotation hole 431 is formed through one side of the end cover 43. A limiting column one 432 is welded to the other side of the end cover 43. A connecting column 44 is rotatably installed inside the second rotation hole 431. A rotating disk 45 is welded to one end of the connecting column 44, and the rotating disk 45 is installed inside the installation cavity 42. A guiding disk 451 is welded to the side of the rotating disk 45 away from the connecting column 44. A limiting column two 452 is welded to the surface of the guiding disk 451. The two ends of a tension spring 46 are fixed by the limiting column one 432 and the limiting column two 452.

[0026] Further, the limiting column one 432 and the limiting column two 452 are connected by the tension spring 46, and the tension spring 46 is installed outside the rotating disk 45. Through the elastic deformation of the tension spring 46, when an external force is applied to stretch the tension spring 46 and then the external force disappears, it will quickly recover, thereby driving the clamping member 5 to rotate, and the sample liquid in the reagent tube can be fully mixed.

[0027] Further, a knob 47 is welded to the side of the guiding disk 451 away from the rotating disk 45 through a connecting shaft, and the connecting shaft is rotatably installed inside the first rotation hole 421. The rotating disk 45 is indirectly driven to rotate through the knob 47, thereby triggering the deformation of the tension spring 46.

[0028] Further, the clamping member 5 includes a main clamping ring 51, a secondary clamping ring 52, and a threaded rod 53. A main clamping ring 51 is welded to the side of the connecting column 44 away from the rotating disk 45. Guide rails 511 are welded to both sides of one end of the main clamping ring 51. A secondary clamping ring 52 is slidably installed on one side of the main clamping ring 51. A slider 521 is welded to one end of the secondary clamping ring 52. A threaded hole 522 is formed through the surface of the slider 521. Guide blocks 523 are welded to both sides of the slider 521, and the guide blocks 523 are slidably installed inside the guide rails 511. A threaded rod 53 is threadedly installed inside the threaded hole 522, and one end of the threaded rod 53 is rotatably installed at one end of the main clamping ring 51 and is located inside the two guide rails 511. When clamping the reagent rod, manually rotating the threaded rod 53 will drive the slider 521 to slide inside the guide rail 511, thereby driving the secondary clamping ring 52 to undergo a relative displacement change with respect to the main clamping ring 51.

[0029] Working principle: First, move the omethoate rapid detection kit to the working position. In the first step, when detecting omethoate residues, first fold and open the support column 4, then clamp the reagent tube inside the main clamping ring 51 and the secondary clamping ring 52, and manually rotate the threaded rod 53. The threaded rod 53 drives the slider 521 to slide inside the guide rail 511 until the reagent tube is clamped. In the second step, cut the sample skin into sample pieces of appropriate size, place them in the reagent tube, and then pour in the diluent for dilution. In the third step, manually rotate the knob 47. The knob 47 indirectly drives the rotating disk 45 to rotate through the connecting shaft. At this time, the rotating disk 45 drives the reagent tube inside the clamping member 5 to rotate synchronously through the connecting column 44. At the same time, the tension spring 46 outside the rotating disk 45 is stretched. In the fourth step, when the tension spring 46 is stretched to the limit value, release the knob 47. At this time, the tension spring 46 resumes its deformation and drives the rotating disk 45 to rotate in the reverse direction. At this time, the clamping member 5 drives the reagent tube to rotate in the reverse direction. Continue this operation until the sample liquid is fully mixed. In the fifth step, insert the test card into the slot 21 inside the test card placement box 2, and use a pipette to suck the sample liquid in the reagent tube to the through-hole 22 position of the test card. The through-hole 22 position coincides with the test hole of the test card. After reacting for a specified time, the display result of the test card will be displayed from the display slot 23, thereby determining whether there is omethoate residue. In this way, the use process of the omethoate rapid detection kit is completed.
