Description
Technical Field
[0001] The utility model relates to the technical field of latex detection, in particular to a melon fruit spot virus latex microsphere detection card. Background Art
[0002] Melons and fruits may encounter various diseases during their growth process, which may cause a 30% to 40% reduction in fruit yield. Common viral diseases include fruit spot, leaf spot, mosaic, mottle, vein banding, etc. In order to facilitate production personnel to detect diseases in time, production personnel usually purchase test cards and select samples for testing by themselves, or directly send them to professional testing institutions for testing using equipment. The existing virus test cards are mainly divided into two types, one is colloidal gold detection, and the other is latex microsphere detection. The structural difference between the two is that latex particles are used instead of colloidal gold particles. Although the cost of latex test cards is relatively high, in most cases, the detection sensitivity of latex test cards is better than that of colloidal gold test cards.
[0003] The invention discloses an anti-pollution colloidal gold detection card with application number 202321981087.6, comprising a base, a placement seat on the base, a colloidal gold test paper on the inner side of the placement seat, a cover plate above the colloidal gold test paper, a liquid inlet hole on the cover plate, an observation hole on the side of the liquid inlet hole, a liquid isolation ring below the liquid inlet hole, the liquid isolation ring is fixedly connected to the cover plate, a groove is provided above the observation hole, a plastic sheet is provided on the inner side of the groove, the plastic sheet and the groove are connected by glue, a first sealing shell is provided on the outer side of the cover plate, and a second sealing shell is provided on the side of the first sealing shell; the utility model has the advantages of good sealing effect and not being easily polluted by the outside when used in nature.
[0004] When using this technical solution, it is necessary to first remove the sealing plate on the side and then rotate to open the semi-enclosed shell. The test card usually has an outer packaging, which requires the disassembly and opening of multiple structures before use. The operation is relatively cumbersome. At the same time, after the semi-enclosed shell is opened and the sample is dripped in, the through hole and sample pad for dripping the sample are exposed. If the test card is accidentally dropped or the test environment is relatively harsh, it is still easy to cause the test card to be contaminated. If the semi-enclosed shell is closed, it is not convenient for users to check. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a melon fruit spot virus latex microsphere detection card to solve the technical problems mentioned in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a melon and fruit spot virus latex microsphere detection card, comprising a shell, a first limit strip connected to one side of the bottom of the shell, a support foot connected to the other side of the bottom of the shell, a second limit strip and a support strip connected to the bottom of the shell respectively, and an elastic strip connected to one side of the support strip, a slide connected to the outer surface of the shell, and a sealing gasket connected to the upper part of the inside of the slide.
[0007] By adopting the above technical scheme, before dropping the sample, the slide is pushed in the direction of the second limit bar, so that the slide drives the sealing gasket to move away from the sample dropping port, so that the sample dropping port is exposed to facilitate the dropping of the sample, and at the same time the slide resists the elastic bar to make the elastic bar bend and deform to accumulate force, and then the slide and the second limit bar resist and cannot continue to slide, so as to avoid the elastic bar from being over-compressed and bending at an excessively large angle to cause breakage. After dropping the sample, the slide is released, and at this time the elastic bar drives the slide to drive the sealing gasket to move in the direction of the sample dropping port, so that the sample dropping port is blocked by the sealing gasket to avoid contamination of the sample pad, and at the same time the first limit bar is used to limit the slide to prevent the slide from falling off, and at this time the test card can be placed on the desktop, and the right side of the outer shell is raised by the supporting feet to avoid the right side of the test card tilting downward after being placed due to the height of the slide.
[0008] Furthermore, the slide is slidably connected to the housing, and the slide is respectively in contact with the first limit strip and the second limit strip.
[0009] By adopting the above technical solution, the user pushes the slide toward the direction of the second limit bar, and the slide resists the second limit bar and cannot continue to slide, thereby preventing the elastic bar from being over-compressed and bent at an excessive angle to cause breakage. The elastic bar drives the slide to drive the sealing gasket to move toward the drip port, and at the same time, the first limit bar limits the slide to prevent it from falling off.
[0010] Furthermore, two spring bars are provided, and both the spring bars and the support bars are made of ABS plastic.
[0011] By adopting the above technical solution, the ABS plastic has good elasticity and can store force after bending, and when the force is released, it pushes the slide to reset so that the sealing pad covers the dripping port.
[0012] Furthermore, one end of the elastic bar is arc-shaped, and the slide bracket abuts against the elastic bar.
[0013] By adopting the above technical solution, after dropping the sample, the user releases the slide, and the spring bar drives the slide to move the sealing pad toward the sample drop port, so that the sample drop port is blocked by the sealing pad to prevent the sample pad from being contaminated.
[0014] Furthermore, the first limiting strip, the second limiting strip and the supporting strip are fixedly connected to the housing by bonding with strong glue.
[0015] By adopting the above technical solution, when producing the detection card, the slide is first sleeved on the outside of the shell, and then the first limit bar, the second limit bar and the support bar formed integrally with the elastic bar are installed and fixed by strong glue.
[0016] Furthermore, a sample drop port is opened on one side of the top of the shell, and a viewing window is opened on the other side of the top of the shell. A substrate is connected to the lower part of the inside of the shell, and the top of the substrate is connected to a sample pad, a latex microsphere pad, a first NC membrane, a test strip, a second NC membrane, a quality inspection strip, a third NC membrane and a water absorbent pad from left to right.
[0017] By adopting the above technical solution, after the sample is dropped into the sample pad, the sample penetrates into the latex microsphere pad, and then the latex microsphere pad reacts with the sample. Then the sample passes through the first NC membrane, the test strip, the second NC membrane, the quality inspection strip and the third NC membrane in sequence and then enters the absorbent pad, so that the sample reacts with the test strip and the quality inspection strip in sequence, and the excess sample and residue are absorbed by the absorbent pad. At this time, if the test strip and the quality inspection strip are both red, it is judged as positive, and the darker the color, the stronger the positive. If only the quality inspection strip is red, it is judged as negative. If the quality inspection strip does not show color, it is judged as invalid regardless of whether the test strip is red, and another test card needs to be used for re-testing.
[0018] Furthermore, a thin plate is connected inside the window.
[0019] By adopting the above technical solution, the window is blocked by a thin plate to prevent the entry of external dust, bacteria and viruses, and to prevent the test strip and the quality inspection strip from being contaminated.
[0020] Furthermore, the thin plate is made of transparent PC material, and the thin plate is fixedly connected to the window by bonding with strong glue.
[0021] By adopting the above technical solution, the transparent thin plate can prevent the detection strip and the quality inspection strip from being contaminated, and at the same time does not affect the user's line of sight, so as to facilitate observation by the user.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model provides a slide, a supporting foot, a first limiting strip, a second limiting strip, a supporting strip, an elastic strip and a sealing pad, and before dripping the sample, the slide is pushed in the direction of the second limiting strip, so that the slide drives the sealing pad to move away from the sample dripping port, thereby exposing the sample dripping port for dripping the sample, and at the same time, the slide resists the elastic strip to bend and deform the elastic strip to store force, and then the slide and the second limiting strip resist and cannot continue to slide, so as to avoid the elastic strip being over-compressed and bending at an excessively large angle to cause breakage, and release the slide after dripping the sample. At this time, the elastic strip drives the slide to drive the sealing pad to move in the direction of the sample dripping port, so that the sample dripping port is blocked by the sealing pad to avoid contamination of the sample pad, and at the same time, the slide is limited by the first limiting strip to avoid falling off. At this time, the test card can be placed on the desktop, and the right side of the shell is raised by the supporting foot to avoid the right side of the test card tilting downward after being placed due to the height of the slide; it is easy to operate, and the sealing of the sample dripping port will not affect observation.

The angle is too large and the breakage phenomenon occurs; one side of the support bar 7 is connected to an elastic bar 8, and two elastic bars 8 are provided. The elastic bar 8 and the support bar 7 are both made of ABS plastic, and one end of the elastic bar 8 is arc-shaped. The slide 3 abuts against the elastic bar 8, and the outer surface of the shell 1 is connected to the slide 3. The slide 3 is slidably connected to the shell 1, and the slide 3 abuts against the first limit bar 5 and the second limit bar 6 respectively. A sealing gasket 9 is connected to the upper part of the slide 3. The elastic bar 8 drives the slide 3 to drive the sealing gasket 9 to move toward the direction of the sample drop port 10, so that the sample drop port 10 is blocked by the sealing gasket 9 to prevent the sample pad 13 from being contaminated.
[0034] See also Figure 5 In the above embodiment, a sample dropping port 10 is provided on one side of the top of the shell 1, and the sample is dropped into the sample dropping port 10 through a dropper; a window 11 is provided on the other side of the top of the shell 1, which is convenient for users to observe the color changes of the detection strip 16 and the quality inspection strip 18; a substrate 12 is connected to the lower part of the inside of the shell 1, and a sample pad 13, a latex microsphere pad 14, a first NC membrane 15, a detection strip 16, a second NC membrane 17, a quality inspection strip 18, a third NC membrane 19 and a water absorbent pad 20 are connected to the top of the substrate 12 from left to right. After the sample is dropped into the sample pad 13, the sample penetrates into the latex microsphere pad 14, and then the latex microsphere pad 14 reacts with the sample, and then the sample passes through the first NC membrane 15, the detection strip 16, the second NC membrane 17, the quality inspection strip 18 and the third NC membrane 19 in sequence and then enters the water absorbent pad 20.
[0035] Embodiment 2:
[0036] On the basis of the above-mentioned embodiment 1, although the frame 3, the supporting foot 4, the first limiting strip 5, the second limiting strip 6, the supporting strip 7, the elastic strip 8 and the sealing gasket 9 are provided to facilitate operation, and the sealing of the drip port will not affect the observation; however, the detection strip 16 and the quality inspection strip 18 may be contaminated; now, by providing a thin plate 2, the detection strip 16 and the quality inspection strip 18 can be prevented from being contaminated.
[0037] See also Figure 1 and Figure 5In the above embodiment, a thin plate 2 is connected to the inside of the window 11. The thin plate 2 is made of transparent PC material. The thin plate 2 is fixedly connected to the window 11 by adhesion with strong glue. The window 11 is blocked by the thin plate 2 to prevent the detection strip 16 and the quality inspection strip 18 from being contaminated.
[0038] The implementation principle of the utility model is as follows: first, the dripping port 10 is shielded by the sealing pad 9, so as to prevent the sample pad 13 from being contaminated during transportation and carrying. Before dripping the sample, the user pushes the slide 3 in the direction of the second limit bar 6 with one hand, so that the slide 3 drives the sealing pad 9 to move away from the dripping port 10, so that the dripping port 10 is exposed, and at the same time, the slide 3 abuts against the elastic bar 8 to bend and deform to store force, and then the slide 3 abuts against the second limit bar 6 and cannot continue to slide, so as to prevent the elastic bar 8 from being over-compressed and bent at an excessively large angle to cause breakage, and then the user drips the sample into the dripping port 10 through a dropper with the other hand;
[0039] After dropping the sample, the user releases the slide 3. At this time, the elastic bar 8 drives the slide 3 to drive the sealing gasket 9 to move toward the sample drop port 10, so that the sample drop port 10 is blocked by the sealing gasket 9 to prevent the sample pad 13 from being contaminated. At the same time, the window 11 is blocked by the thin plate 2 to prevent the detection strip 16 and the quality inspection strip 18 from being contaminated. At the same time, the slide 3 is limited by the first limit bar 5 to prevent the slide 3 from falling off. At this time, the user can place the test card on the desktop to wait for testing, and at the same time, the right side of the housing 1 is raised by the supporting foot 4 to prevent the height of the slide 3 from causing the right side of the test card to tilt downward after being placed, or the user directly puts the test card into a pocket or bag;
[0040] After the sample is dropped into the sample pad 13, the sample penetrates into the latex microsphere pad 14, and then the latex microsphere pad 14 reacts with the sample. Then the sample passes through the first NC membrane 15, the test strip 16, the second NC membrane 17, the quality inspection strip 18 and the third NC membrane 19 in sequence and then enters the absorbent pad 20, so that the sample reacts with the test strip 16 and the quality inspection strip 18 in sequence, and the excess sample and residue are absorbed by the absorbent pad 20. At this time, if the test strip 16 and the quality inspection strip 18 are both red, it is judged as positive, and the darker the color, the stronger the positive. If only the quality inspection strip 18 is red, it is judged as negative. If the quality inspection strip 18 does not show color, it is judged as invalid regardless of whether the test strip 16 is red, and another test card needs to be used for re-testing.
