[0006] By adopting the above technical scheme, after the staff has installed the test paper, the staff rotates the shell. During the rotation, the pressure plate in the shell can press against the test paper through the first spring to make it difficult for the test paper to leave the storage slot. When the shell closes the device body, the card plate is pushed into the card slot by the second spring and abuts against the card slot to lock the shell. At the same time, the four magnetic plates are sucked out of the device body by the magnetic block through the attraction between the magnetic block and the magnetic plate, and the gap between the device body and the shell is filled with the rubber pad on one side of the magnetic plate, thereby minimizing the entry of external dust into the test card to contaminate the test paper. When the test is completed and the staff needs to replace the test paper, the staff pulls the pull rod, and the pull rod drives the card plate to move to the left through the connecting frame so that the card plate no longer limits the card slot, so that the staff can pull and rotate the shell to replace the test paper. The baffle can press against the limiting slot in the magnetic plate, making it difficult for the magnetic plate to be sucked out when the magnetic block leaves.

[0007] Furthermore, a liquid inlet hole and an observation port are provided on the top of the shell.

[0008] By adopting the above technical solution, the staff can drop the test liquid onto the test paper through the liquid inlet, and the staff can monitor the test paper through the observation port.

[0009] Furthermore, the observation port is made of transparent PC.

[0010] By adopting the above technical solution, the observation port made of transparent PC can make the observation port difficult to be accidentally damaged and more durable.

[0011] Furthermore, one side of the card plate and the bottom of the magnetic block are both sloped, two magnetic blocks and two magnetic plates are provided, and a rubber pad is provided on one side of the magnetic plate.

[0012] By adopting the above technical solution, the cross section on the card plate makes it difficult for the card plate to resist the device body when it rotates downward, making it difficult for the shell to rotate; the inclined surface on the magnetic block makes it difficult for the magnetic block to resist the magnetic plate when it rotates downward, making it difficult for the shell to continue rotating.

[0013] Furthermore, a card slot is provided on one side of the device body, and the card plate abuts against the card slot.

[0014] By adopting the above technical solution, when the shell closes the device body, the locking plate is pushed into the locking slot by the second spring and abuts against the locking slot to lock the shell.

[0015] Furthermore, a limiting groove is provided inside the magnetic plate, and the baffle plate abuts against the limiting groove.

[0016] By adopting the above technical solution, the baffle plate can abut against the limiting groove in the magnetic plate, so that the magnetic plate will not be sucked out when the magnetic block leaves.

[0017] Furthermore, two pressing plates are provided, and the two pressing plates are hemispherical.

[0018] By adopting the above technical solution, the two pressing plates can better clamp the test paper, and the hemispherical pressing plate prevents the pressing plate from damaging the test paper.

[0019] Furthermore, the pressing plate is made of graphene material.

[0020] By adopting the above technical solution, the graphene material has antibacterial and antiviral effects, making it difficult for bacteria and viruses to adhere thereto.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] The utility model is provided with a shell, a first spring, a pressure plate, a second spring, a magnetic block, a magnetic plate and a baffle. After the staff has installed the test paper, the staff rotates the shell. During the rotation, the pressure plate in the shell can press against the test paper through the first spring, so that the test paper is difficult to escape from the storage slot. When the shell closes the device body, the card plate is pushed into the card slot by the second spring and abuts against the card slot to lock the shell. At the same time, the magnetic block and the magnetic plate are attracted to each other, so that the four magnetic plates are sucked out of the device body by the magnetic block, and the gap between the device body and the shell is filled by the rubber pad on one side of the magnetic plate. And minimize the outside dust from entering the test card to contaminate the test paper. When the test is completed and the staff needs to replace the test paper, the staff pulls the pull rod, and the pull rod drives the card plate to move to the left through the connecting frame so that the card plate no longer limits the card slot, so that the staff can rotate the shell to replace the test paper. The baffle plate can resist the limiting slot in the magnetic plate, making it difficult for the magnetic block to suck out the magnetic plate when it leaves. Through the above operation and structure, the work efficiency of the staff is improved, the detection quality of the test paper is protected, the speed of test paper replacement is increased, the structure is simple, and the design is reasonable.

The test paper is made of The device body 1 is composed of a substrate, a sample pad, a gold pad, three NC films, a detection line, a quality control line and a water absorbent pad. A guide rod 15 is connected inside the device body 1. The guide rod 15 supports and guides the magnetic plate 16. The outer surface of the guide rod 15 is provided with a magnetic plate 16 and a baffle 17. The baffle 17 is fixedly connected to the guide rod 15. A rubber pad is provided on one side of the magnetic plate 16. The magnetic block 14 and the magnetic plate 16 are attracted to each other, so that the four magnetic plates 16 are sucked out of the device body 1 by the magnetic block 14, and the gap between the device body 1 and the shell 3 is filled by the rubber pad on one side of the magnetic plate 16.

[0032] See also Figure 1-Figure 3 In the above embodiment, a liquid inlet hole 4 and an observation port 5 are provided on the top of the shell 3. The staff can drip the test liquid onto the test paper through the liquid inlet, and the staff can monitor the test paper through the observation port 5. The observation port 5 is made of transparent PC. The observation port 5 made of transparent PC can make the observation port 5 difficult to be accidentally damaged and more durable. A limiting groove 18 is provided inside the magnetic plate 16, and the baffle 17 is in contact with the limiting groove 18. The baffle 17 can abut the limiting groove 18 in the magnetic plate 16, so that when the magnetic block 14 leaves, the magnetic plate 16 will not be sucked out.

[0033] See also Figure 1-Figure 2 In the above embodiment, two pressing plates 7 are provided, and the two pressing plates 7 are hemispherical. The two pressing plates 7 can better clamp the test paper. The hemispherical pressing plates 7 prevent the pressing plates 7 from damaging the test paper in the storage slot 13. The pressing plates 7 are made of graphene material, which has antibacterial and antiviral effects and can make it difficult for bacteria and viruses to adhere thereto.

[0034] Embodiment 2:

[0035] On the basis of the above-mentioned embodiment 1, although the setting of the magnetic block 14 and the magnetic plate 16 can play a certain fixing role on the shell 3 and the device body 1; the shell 3 may be accidentally opened due to the influence of external force; now through the setting of the card plate 9, the connecting frame 10, the pull rod 11 and the card slot 12, the shell 3 can be fixed more firmly.

[0036] See also Figure 1 , Figure 2 and Figure 4 In the above embodiment, one side of the card plate 9 and one side of the bottom of the magnetic block 14 are both sloped, and two magnetic blocks 14 and magnetic plates 16 are provided. The cross section on the card plate 9 makes it difficult for the card plate 9 to abut against the device body 1 when it rotates downward, making it difficult for the shell 3 to rotate. The inclined surface on the magnetic block 14 makes it difficult for the magnetic block 14 to abut against the magnetic plate 16 when it rotates downward, making it difficult for the shell 3 to continue to rotate. A card slot 12 is provided on one side of the device body 1, and the card plate 9 abuts against the card slot 12. When the shell 3 closes the device body 1, the card plate 9 is pushed into the card slot 12 by the second spring 8 and abuts against the card slot 12 to lock the shell 3.

[0037] The implementation principle of the utility model is as follows: first, the staff presses the test paper into the storage slot 13. After the staff installs the test paper, the staff rotates the shell 3. During the rotation, the pressure plate 7 in the shell 3 can press the test paper through the first spring 6 to make it difficult for the test paper to escape from the storage slot 13. When the shell 3 closes the device body 1, the card plate 9 is pushed into the card slot 12 by the second spring 8 and abuts against the card slot 12 to lock the shell 3. At the same time, the magnetic block 14 and the magnetic plate 16 are attracted to each other, so that the four magnetic plates 16 are sucked out of the device body 1 by the magnetic block 14, and the gap between the device body 1 and the shell 3 is filled by the rubber pad on one side of the magnetic plate 16, thereby minimizing the external dust from entering the detection card to contaminate the test paper;

[0038] During the test, the staff drips the sample to be tested into the liquid inlet 4, so that the sample enters the sample pad of the test paper. After the sample drips into the sample pad, the staff waits for a while. At this time, the sample penetrates into the gold pad, and then the gold pad dyes the sample. The dyed sample swims along the NC membrane toward the absorbent pad. There is an antigen in the test line, and there is a secondary antibody in the quality control line. If there is an antigen in the sample, it will combine with the test line and the quality control line to change the color of the test line and the quality control line. At this time, the staff can see two red lines through the observation port 5, indicating that the pomegranate mosaic virus test is positive. If there is no antigen in the sample, it will only combine with the quality control line to change the color of the quality control line. At this time, the staff can see a red line through the viewing hole and the window, indicating that the pomegranate mosaic virus test is negative. If the quality control line does not change color, it means that the colloidal gold test card has been damaged and cannot perform normal testing work;

[0039] When the test is completed and the staff needs to replace the test paper, the staff pulls the pull rod 11, and the pull rod 11 drives the card plate 9 to move to the left through the connecting frame 10 so that the card plate 9 no longer limits the card slot 12, so that the staff can rotate the shell 3 to replace the test paper, and the baffle 17 can resist the limiting slot 18 in the magnetic plate 16, making it difficult for the magnetic block 14 to suck out the magnetic plate 16 when leaving.

[0040] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
