Description
Technical Field
[0001] The utility model relates to the technical field of pesticide residue detection cards, in particular to a pollution-proof dichlorvos residue detection card. Background Art
[0002] Dichlorvos is a broad-spectrum insecticide and acaricide. It decomposes quickly after application, has a short lasting effect, and leaves no residue. It can be applied shortly before harvest to control piercing-sucking and chewing pests. Therefore, it is suitable for fruit trees such as apples, pears, and grapes, as well as vegetables, mushrooms, tea trees, mulberry trees, and tobacco.
[0003] There are many methods for detecting dichlorvos residues in fruits and vegetables in the prior art. Among them, a test card is widely used. The test card is first folded in half along the center line (to facilitate subsequent folding), then unfolded and laid on an operating table, and then a test reagent is dropped on the vegetable leaves. The vegetable leaves with the test reagent are then rubbed with another vegetable leaf for about 10 seconds, and then the rubbed liquid is poured onto the white tablet on the test card. After standing for 10 minutes, the folded test card is folded in half again, so that the other tablet is superimposed on the white tablet, so that the tablets react, thereby obtaining a result of whether the dichlorvos residue in the vegetables exceeds the standard;
[0004] In some non-laboratory testing environments, when the user drops the test reagent on the tablet and then folds it, they usually pick up the test card as a whole. Since the test card is thin and small in size, the test reagent can easily flow everywhere during this process. The folded test card will further increase the fluidity of the test reagent after being subjected to pressure, which not only prevents the test reagent from being concentrated in the tablet area, but also causes part of the test reagent to flow onto the user's hands or other objects, resulting in waste of test reagent, contamination of the user's hands and other objects, and prevents the test reagent from fully contacting the tablet. Utility Model Content
[0005] The purpose of the utility model is to provide a pollution-proof dichlorvos residue detection card to solve the problems raised in the above background technology.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.
[0026] See also Figure 1-5 The utility model provides an anti-pollution dichlorvos residue detection card, comprising a protective shell 1 and a detection card 2, the detection card 2 is placed inside the protective shell 1, the detection card 2 comprises two mutually hinged sample cards 3 and a rapid test card 4, the surface of the sample card 3 is fixedly provided with a first protective ring 5, the surface of the rapid test card 4 is fixedly provided with a second protective ring 6, the inner diameter and outer diameter of the first protective ring 5 and the second protective ring 6 are the same, a movable ring 7 is movably provided above the rapid test card 4, a detection tablet 8 is bonded to the top of the movable ring 7, a base plate 9 is fixedly provided on the inner wall of the rapid test card 4, a spring 10 is fixedly provided between the base plate 9 and the movable ring 7, a connecting shaft 11 is provided on the movable ring 7 through a smearing mechanism, the connecting shaft 11 passes through and is rotatably connected to the base plate 9, and a pulling part 12 is fixed to the bottom of the connecting shaft 11.
[0027] See also Figure 2 and 4 When in use, the test reagent is dropped directly onto the surface of the sample card 3. Under the restriction of the first protective ring 5, the test reagent will not flow everywhere. Then, the rapid test card 4 is flipped over while pulling the pulling part 12. The pulling part 12 can drive the smoothing mechanism to retract through the connecting shaft 11, so that the movable ring 7 drives the detection tablet 8 to move toward the direction close to the rapid test card 4, and compresses the spring 10 to store energy. After the rapid test card 4 is flipped 180°, the first protective ring 5 and the second protective ring 6 conflict with each other. At this time, the pulling part 12 is released, and the spring 10 can release energy, thereby driving the movable ring 7 and the detection tablet 8 to press against the surface of the sample card 3 through the smoothing mechanism. The first protective ring 5 and the second protective ring 6 can cooperate to restrict the flow of the test reagent, so that the test reagent can fully contact the detection tablet 8, and the user's hands and other objects will not be contaminated by the flow of the test reagent.
[0028] It should be noted that the outer diameter of the movable ring 7 is the same as the inner diameter of the second protective ring 6, and the diameter of the detection tablet 8 is larger than the inner diameter of the movable ring 7 and smaller than the outer diameter of the movable ring 7. This structure is to enable the detection tablet 8 to be fully immersed in the test reagent.
[0029] The smoothing mechanism includes a slide 13, a smoothing plate 14 and a spherical protrusion 15. The spherical protrusion 15 is fixedly arranged at both ends of the smoothing plate 14, and the connecting shaft 11 is fixed to the center of the smoothing plate 14. The slide 13 is arranged on the inner wall of the movable ring 7, and the smoothing plate 14 is rotatably arranged on the inner wall of the movable ring 7. The spherical protrusion 15 is slidably arranged in the slide 13. A connecting arm 16 is fixedly arranged on the surface of the connecting shaft 11, and a disc 17 is fixedly installed on the bottom of one end of the connecting arm 16. The side wall of the disc 17 is in contact with the inner wall of the quick test card 4. The side surfaces of both ends of the smoothing plate 14 are arranged to have the same arc structure as the inner wall of the movable ring 7. The side wall of the smoothing plate 14 is in contact with the inner wall of the movable ring 7. A sinking groove 18 is arranged in the center of the disc 17, and the cross-section of the sinking groove 18 is arranged to have a trapezoidal structure.
[0030] See also Figure 2 、 3 , 4 and 5. After the rapid test card 4 is flipped 180°, in order to allow the test tablet 8 to further fully contact the test reagent, the user needs to keep the folded state of the rapid test card 4 and the sample card 3 unchanged. After releasing the pulling part 12, the user clamps the open ends of the rapid test card 4 and the sample card 3 with the index finger and middle finger, and then places the thumb on the sinking groove 18 to push the disc 17 to revolve inside the rapid test card 4. At this time, the disc 17 can drive the connecting shaft 11 to rotate through the connecting arm 16. When the connecting shaft 11 rotates, it can drive the smearing plate 14 to rotate on the inner wall of the movable ring 7. Since the test tablet 8 is made of flexible material, the smearing plate 14 can continuously scrape the back of the test tablet 8 during rotation, so that it is in full contact with the test reagent.
[0031] It should be noted that when the smoothing plate 14 rotates, it can drive the spherical protrusion 15 to rotate synchronously inside the slide groove 13. The setting of the slide groove 13 and the spherical protrusion 15 can prevent the smoothing plate 14 from falling off from the inside of the movable ring 7, and can limit the movement process of the smoothing plate 14.
[0032] The inner wall of the protective shell 1 is integrally formed with a track 19 , the side walls of the rapid test card 4 and the sample card 3 are both provided with grooves 20 , and a tin sealing sheet 21 is bonded to one end of the protective shell 1 .
[0033] See also Figure 1 and 2 By setting the groove 20 and the track 19, the detection card 2 can be kept parallel as a whole and fixed inside the protective shell 1 for easy transportation and transfer, and the setting of the tin sealing sheet 21 can seal the protective shell 1, thereby increasing the sealing performance of the protective shell 1 and preventing the rapid test card 4 and the sample card 3 from being contaminated by external impurities.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
