[0022] Next, embodiments of the technical solution of the present utility model will be described in detail with reference to the attached drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0023] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the field to which the present utility model belongs.

[0024] Referring to Figures 1-5 , an immunofluorescence layer detection card for a canine coronavirus antigen includes a sealed box 1. A first chute 2 and a limit groove 3 are opened on the upper surface of the sealed box 1. The lower ends of the first chute 2 and the limit groove 3 are both communicated with the inside of the sealed box 1. One end of the first chute 2 is communicated with one end of the limit groove 3. A pair of symmetrically distributed first springs 4 are fixedly connected to one inner wall of the sealed box 1. One end of each of the two first springs 4 is fixedly connected to a push block 5. The push block 5 is in a limited state in the storage state. The outer surface of the push block 5 is slidably sleeved with the inner wall of the sealed box 1. A second chute 6 is opened on the upper surface of the push block 5;

[0025] One end of the second chute 6 is communicated with the inner top wall of the push block 5. A second spring 7 is fixedly connected to the front inner wall of the push block 5.

[0026] Furthermore, one end of the second spring 7 is fixedly connected to a square block 8. The outer surface of the square block 8 is slidably sleeved with the inner wall of the push block 5. When there is no external force, the square block 8 is at the farthest side of the inner wall of the push block 5.

[0027] Furthermore, a cylindrical block 9 is fixedly connected to the upper surface of the square block 8. One end of the cylindrical block 9 penetrates and extends to the upper surface of the sealing box 1, and the outer surface of the cylindrical block 9 is slidably inserted into the inner wall of the second chute 6.

[0028] Furthermore, the outer surface of the cylindrical block 9 is slidably inserted into the inner wall of the limiting groove 3. When using the detection card, the cylindrical block 9 is pushed so that it is no longer located in the limiting groove 3, so that the pushing block is no longer in the limiting state. One side surface of the pushing block 5 reset by the first spring 4 is fixedly connected with symmetrically distributed connecting rods 10.

[0029] Furthermore, one end of each of the two connecting rods 10 is fixedly connected with a sealing plate 11. The outer surface of the sealing plate 11 is slidably sleeved on the inner wall of the sealing box 1. The sealing plate 11 isolates the detection card body 12 from the transmission part in the sealing box 1.

[0030] Furthermore, a detection card body 12 is fixedly connected to one side surface of the sealing plate 11. An installation square ring 13 is fixedly connected to the outer surface of the sealing box 1. One side surface of the installation square ring 13 is fixedly connected with first connecting columns 14 distributed in a rectangular array. One side surface of each of the plurality of first connecting columns 14 is fixedly connected with a tearing strip 15. One end of the tearing strip 15 is fixedly connected with a pull ring 16.

[0031] Furthermore, second connecting columns 17 distributed in a rectangular array are fixedly connected to one side surface of the tearing strip 15. One side surface of each of the plurality of second connecting columns 17 is fixedly connected with a sealing cover 18. The sealing cover 18 cooperates with the sealing plate 11 to make the detection card body 12 in a sealed space, so that it is not polluted by the outside world and the storage time of the detection card body 12 is prolonged. The inner wall of the sealing cover 18 is slidably sleeved on the outer surface of the sealing box 1. One side inner wall of the sealing cover 18 is fixedly connected with a sealing film 19. One side surface of the sealing film 19 contacts the one side surface of the sealing box 1.

[0032] Through the mutual cooperation of the sealing cover and the sealing plate, the detection card body is in a sealed space and is not polluted by the outside world, which can effectively prolong the storage time of the detection card body. And when in use, the detection card body can be popped out very conveniently, which is convenient to use.

[0033] Working principle: Step 1, when the immunofluorescence layer detection card for canine coronavirus antigen is in the storage state, the elastic force of the second spring 7 causes the outer surface of the cylindrical block 9 to contact the inner wall of the limiting groove 3 through the square block 8. The limiting effect of the limiting groove 3 keeps the pushing block in a limited state, so that the first spring 4 is in a compressed state. At this time, the sealing cover 18 and the sealing plate 11 cooperate with each other to make the detection card body 12 in a sealed space, preventing it from being contaminated by the outside, extending the storage time of the detection card body 12. When it is needed to use, hold the pull ring 16 and pull it, driving the separation of the tearing strip 15 from the connection between the first connecting column 14 and the second connecting column 17. At this time, there is no fixed connection relationship between the sealing cover 18 and the sealing box 1, and the sealing cover 18 can be removed;

[0034] Step 2, push the cylindrical block 9 so that it is no longer in the limiting groove 3, so that the pushing block is no longer in a limited state, and the first spring 4 resets. The first spring 4 drives the connecting rod 10 to move through the pushing block 5. The connecting rod 10 drives the detection card body 12 to move through the sealing plate 11, so as to eject the detection card body 12. At this time, the detection card body 12 can be used to detect the canine coronavirus antigen.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
