Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] like Figures 1 to 4 As shown, a tetracycline-based fluorescent quantitative detection card structure includes an upper shell 1 and a lower shell 2, which are symmetrically positioned vertically. A detection lamp 6 is fixed inside the lower shell 2. A test strip mounting slot 3 is provided in the middle of the upper surface of the upper shell 1. A test strip 4 is detachably placed inside the test strip mounting slot 3, and the test strip 4 is located directly above the detection lamp 6. Rotary insertion holes 7 are provided on both sides of the inner wall of the test strip mounting slot 3. Two symmetrically positioned rotating pressure blocks 5 are rotatably mounted inside the test strip mounting slot 3. Rotary positioning rods 8 are slidably mounted at both ends of the rotating pressure blocks 5. One end of the rotating positioning rod 8 is inserted into the inner side of the rotating insertion hole 7. The rotating positioning rod 8 ensures that the rotating pressure block 5 can rotate around the axis of the rotating positioning rod 8, thereby pressing or releasing the end of the test strip 4, thus realizing the installation or replacement of the test strip 4.
[0022] The rotating pressure block 5 includes a rotating strip 52. The side of the rotating strip 52 facing the end of the test paper mounting slot 3 is an arc surface. The interior of the rotating strip 52 is provided with a guide groove 55. The two ends of the guide groove 55 are flush with the two ends of the rotating strip 52. The rotating positioning rod 8 is slidably inserted into the inner side of the guide groove 55. A sliding plate 9 is fixed to the outer surface of one end of the rotating positioning rod 8. The sliding plate 9 is slidably installed in the guide groove 55, and one side of the sliding plate 9 extends through the guide groove 55 to the outside of the rotating strip 52. The position of the rotating positioning rod 8 in the guide groove 55 is adjusted by the sliding plate 9, so that the rotating positioning rod 8 is connected or separated from the rotating insertion hole 7, thereby realizing the connection or separation of the rotating strip 52 and the upper housing 1, which facilitates the overall installation or replacement of the rotating pressure block 5.
[0023] Two rotating strips 52 are fixed with a hand pulling plate 51 and an elastic pressing plate 53 on the side facing each other, the hand pulling plate 51 is parallel to the upper surface of the upper shell 1, one side of the elastic pressing plate 53 is inclined downward, the side of the elastic pressing plate 53 inclined downward is fixed with a pressing strip 54, the outer surface of the pressing strip 54 is arc-shaped, the elastic pressing plate 53 with elasticity is used to extrude the pressing strip 54 downward, the test paper 4 is pressed by the smooth outer surface of the pressing strip 54, and the end part of the test paper 4 is ensured not to be broken or damaged during and after the pressing process.
[0024] Working principle: when the fluorescence quantitative detection card structure is used for detecting tetracycline antibiotics, first, the hand pulling plate 51 is pulled upward, so that the hand pulling plate 51 drives the rotating strip 52, the elastic pressing plate 53 and the pressing strip 54 to rotate around the axis of the rotating positioning rod 8, so that the pressing strip 54 is separated from the bottom surface of the test paper installation card slot 3, at this time, the test paper 4 is placed inside the test paper installation card slot 3, and the two ends of the test paper 4 are located below the two pressing strips 54, at this time, the hand pulling plate 51 is rotated to reset, the elastic pressing plate 53 and the pressing strip 54 are rotated to reset by the rotating strip 52, the pressing strip 54 rotating downward contacts and applies pressure to the test paper 4, with the continuous rotation of the elastic pressing plate 53, the elastic pressing plate 53 deforms elastically, and the pressing strip 54 slides on the surface of the test paper 4, the test paper 4 is fixed by the reset elastic pressing plate 53 and the pressing strip 54, then the staff can drop tetracycline antibiotics on the test paper 4 for detection, after the detection is completed, only the hand pulling plate 51 is rotated upward, so that the pressing strip 54 is separated from the end part of the test paper 4, the used test paper 4 can be taken out, and then a new test paper 4 can be replaced, so that the test paper can be quickly replaced, the operation preparation time is shortened, and the detection efficiency is improved.
