[0030] like Figure 1-Figure 5 As shown, the embodiment of the present invention provides a portable colorimetric mechanism for a fluorescent quantitative detection card, comprising a base 1, a cylinder 2 is fixed on the base 1, a transparent placement box 11 is fixed on the circumferential surface of the cylinder 2, the transparent placement box 11 is used to store the fluorescent quantitative detection card, a rotating shaft 3 is provided inside the cylinder 2, a connecting member 4 is provided between the cylinder 2 and the rotating shaft 3, the connecting member 4 is used for positioning and rotating a regular polygonal block 5 after it is raised from the cylinder 2, a regular polygonal block 5 is fixed on the rotating shaft 3, a plurality of chromatographic plates 6 are fixed on the side of the regular polygonal block 5, and the regular polygonal block 5 is rotated to drive the chromatographic plates 6 to rotate, thereby achieving Now let's compare the colorimetry with the fluorescence quantitative detection card placed in the transparent placement box 11. The regular polygonal block 5 is fixed with an upper cover 7, and the upper cover 7 is fixed with a handle 9. The above structure together constitutes a colorimetric device, which realizes the colorimetry of the fluorescence quantitative detection card. When carrying the colorimetric device, the regular polygonal block 5 can be moved down into the cylinder 2, and the chromatographic plate 6 can be protected by the cylinder 2 to prevent the chromatographic plate 6 from being touched or contaminated during carrying, thereby not affecting the subsequent comparison accuracy with the fluorescence quantitative detection card. In addition, the regular polygonal block 5 is moved into the cylinder 2 to reduce the occupied area of ​​the entire colorimetric device, thereby improving the portability of the colorimetric device.

[0031] like Figure 1 As shown, in this embodiment, an inclined guide surface 12 is provided on the inner wall side of the transparent placement box 11 near the top, and the fluorescent quantitative detection card is conveniently inserted into the transparent placement box 11 through the guidance of the inclined guide surface 12.

[0032] like Figure 3As shown, in this embodiment, a rubber pad 10 is fixed to the bottom of the base 1. The rubber pad 10 is used to increase the friction between the base 1 and the desktop, so that the entire colorimetric device is more stable and reliable when placed on the desktop for use.

[0033] like Figure 3 As shown, in this embodiment, the connecting member 4 includes a magnet ring 41 fixed to the inner wall of the cylinder 2. When comparing colors, the inner wall of the magnet ring 41 is rotatably connected to the circumferential surface of the rotating shaft 3. The circumferential surface of the rotating shaft 3 is fixedly sleeved with a lower ring 43. The lower ring 43 is rotatably connected to the upper ring 42. The bottom of the upper ring 42 is provided with an annular connecting groove 45. A connecting ring 44 is fixed to the lower ring 43. The connecting ring 44 is rotatably connected in the annular connecting groove 45. The upper ring 42 is magnetically attracted to the bottom of the magnet ring 41. The bottom of the upper cover 7 It is inlaid with a metal ring 8, and the metal ring 8 and the upper ring 42 are both made of metal iron. After the upper ring 42 moves upward, it is magnetically attracted by the magnet ring 41 to achieve magnetic positioning of the upper ring 42. After magnetic positioning, the rotating shaft 3 can be positioned in the vertical direction. When comparing colors, the upper cover 7 is rotated to drive the regular polygon block 5 and the rotating shaft 3 to rotate. The rotating shaft 3 drives the connecting ring 44 to rotate along the inner wall of the annular connecting groove 45 through the lower ring 43, and the regular polygon block 5 drives the chromatographic plate 6 to rotate, thereby achieving colorimetry.

[0034] like Figure 3 As shown, in this embodiment, the connecting ring 44 is in an inverted isosceles trapezoid, and the shape of the annular connecting groove 45 is adapted to the shape of the connecting ring 44, preventing the lower ring 43 from separating from the upper ring 42 in the vertical direction, making the rotation of the lower ring 43 more stable.

[0035] like Figure 4 As shown, in this embodiment, a clamping block 47 is fixed on the upper ring 42, and an annular groove 46 is provided at the bottom of the magnet ring 41. When comparing colors, the clamping block 47 is clamped in the annular groove 46. The clamping block 47 is inserted into the annular groove 46 to realize the re-positioning of the upper ring 42, preventing the upper ring 42 from separating from the magnet ring 41 during the rotation of the regular polygon block 5, ensuring the positioning stability of the upper ring 42, and making the rotation of the regular polygon block 5 more stable and smooth.

[0036] like Figure 5As shown, in this embodiment, the clamping block 47 includes an inverted V-shaped piece 473, an arc-shaped piece 472 and a connecting block 471 connected in sequence from top to bottom. The connecting block 471 is fixed on the upper ring 42. The side surfaces of the inverted V-shaped piece 473, the arc-shaped piece 472 and the connecting block 471 are all in contact with the side surfaces of the inner wall of the annular groove 46. When the upper ring 42 moves upward, it drives the clamping block 47 to move upward so that the clamping block 47 is inserted into the annular groove 46. The side surfaces of the inner wall of the annular groove 46 squeeze the inclined surface of the inverted V-shaped piece 473, causing deformation at the inverted V-shaped piece 473 and the arc-shaped piece 472. When the upper ring 42 is in contact with the bottom of the magnet ring 41, the inverted V-shaped piece 473 and the arc-shaped piece 472 are inserted into the annular groove 46. The inverted V-shaped piece 473 and the arc-shaped piece 472 are stuck in the annular groove 46 under the action of their own elastic force, thereby realizing the re-positioning of the upper ring 42.

[0037] like Figure 5 As shown, in this embodiment, the width of the inverted V-shaped piece 473 is smaller than the width of the arc-shaped piece 472. After the block 47 is inserted into the annular groove 46, the inverted V-shaped piece 473 is used to guide the block 47 when it is inserted into the annular groove 46. After the block 47 is inserted into the annular groove 46, the arc-shaped piece 472 is positioned in the annular groove 46 to achieve positioning of the upper ring 42.

[0038] Working principle: When carrying, press the upper cover 7, so that the upper cover 7 drives the rotating shaft 3 downward through the regular polygon block 5, and the rotating shaft 3 drives the connecting ring 44 downward through the lower ring 43, and the connecting ring 44 drives the upper ring 42 downward. The upper ring 42 separates from the magnet ring 41 and drives the clamping block 47 downward. The inner wall of the annular groove 46 squeezes the arc piece 472 on the clamping block 47, causing the arc piece 472 to deform. The upper ring 42 drives the clamping block 47 downward to separate the clamping block 47 from the annular groove 46. After separation, continue to move the upper cover 7 downward to make the upper cover The bottom of the upper cover 7 is fitted with the top of the magnetic ring 41, and the metal ring 8 at the bottom of the upper cover 7 is attracted by the magnetic ring 41 to realize the positioning of the upper cover 7. At this time, the chromatographic plate 6 on the regular polygonal block 5 moves into the cylinder 2. The cylinder 2 protects the chromatographic plate 6 on the regular polygonal block 5 to prevent the chromatographic plate 6 from being touched or contaminated during the carrying process, thereby not affecting the subsequent comparison accuracy with the fluorescent quantitative detection card. At the same time, the regular polygonal block 5 is moved into the cylinder 2, which reduces the occupied area of ​​the entire colorimetric device, thereby improving the portability of the colorimetric device.

[0039] Before color comparison is required, pull up the handle 9 so that the handle 9 drives the upper cover 7 to move upward. When the upper cover 7 drives the regular polygon block 5 and the rotating shaft 3 to move upward, the upper cover 7 drives the metal ring 8 to separate from the magnet ring 41. When the rotating shaft 3 moves upward, it drives the lower ring 43 to move upward. The lower ring 43 drives the upper ring 42 to move upward. When the upper ring 42 fits with the bottom of the magnet ring 41, the upper ring 42 is magnetically attracted by the magnet ring 41 to achieve magnetic positioning of the upper ring 42. When the upper ring 42 moves upward, it drives the clamping block 47 to move upward so that the clamping block 47 is inserted into the annular groove 46. The side surface of the inner wall of the annular groove 46 squeezes the inclined surface of the inverted V-shaped piece 473, causing the inverted V-shaped piece 473 and the arc piece 472 to deform. When the upper ring 42 fits with the bottom of the magnet ring 41, the clamping block 47 is inserted into the annular groove 46. The inverted V-shaped piece 473 and the arc piece 472 are deformed. Under the action of its own elastic force, it is stuck in the annular groove 46 to achieve re-positioning of the upper ring 42, and the stable positioning of the rotating shaft 3 is achieved through the cooperation of the magnetic ring 41 and the blocking block 47. Then, the fluorescent quantitative detection card is inserted into the transparent placement box 11. When performing colorimetry, the upper cover 7 is rotated to drive the upper cover 7 to rotate the regular polygon block 5 and the rotating shaft 3. The rotating shaft 3 drives the connecting ring 44 on the lower ring 43 to rotate along the inner wall of the annular connecting groove 45 at the bottom of the upper ring 42. The cooperation of the lower ring 43, the connecting ring 44, the upper ring 42 and the blocking block 47 prevents the upper ring 42 from rotating with the rotating shaft 3, so that the rotation of the rotating shaft 3 and the regular polygon block 5 is more stable. During the rotation of the regular polygon block 5, the chromatographic plate 6 is driven to rotate, thereby realizing colorimetry of the chromatographic plate 6 and the fluorescent quantitative detection card. After the colorimetry is completed, the fluorescent quantitative detection card can be taken out of the transparent placement box 11.

To provide a thorough understanding of the present invention, specific details are described in detail in the preferred embodiments of the present invention above, but those skilled in the art can fully understand the present invention without these detailed descriptions.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
