Abstract
Description
Technical Field
[0001] This utility model relates to the field of molecular diagnostic equipment technology, and specifically to a fluorescence detection mechanism for molecular diagnostic equipment. Background Technology
[0002] The fluorescence detection mechanism of molecular diagnostic equipment is an important component of molecular diagnostic technology. It uses fluorescence signals to perform qualitative and quantitative analysis of biomolecules. Patent publication number CN221612715U discloses a fluorescence detection mechanism for molecular diagnostic equipment, which belongs to the field of molecular diagnostic equipment technology. It includes a base, a shell at the upper end of the base, an end cap at the upper end of the shell, a lifting component on one side of the shell, a lower connection port at the lower end surface of the base, and an upper connection port at the upper end surface of the end cap.
[0003] The above patents utilize a drive motor to rotate a lead screw, which in turn moves a slider. This, in turn, causes the base and end cap to rise and fall via a connecting plate, adjusting the housing height to accommodate workers of different heights. The protective cover is placed on the surfaces of the upper and lower connecting ports and is magnetically secured with a magnet, preventing dust from entering and contaminating the conductive terminals, thus providing excellent protection. However, fluorescence detectors face several challenges in practical use, such as light and humidity interference. External light can interfere with the fluorescence signal, and excessive humidity can affect the quality and stability of the fluorescence probe, thereby impacting the detection results. Currently, fluorescence detection mechanisms lack anti-interference structures, and this issue should be addressed specifically.
[0004] Therefore, a fluorescence detection mechanism for molecular diagnostic equipment is proposed. Utility Model Content

[0023] like Figures 1 to 3As shown, a fluorescence detection mechanism of a molecular diagnostic device includes a worktable 1, a fluorescence detector 2, and a control box 7. The control box 7 is fixedly installed at the bottom of the worktable 1. A vertical plate 3 is fixedly installed on the top of the worktable 1. The top of the worktable 1 is provided with an adjustment mechanism 4 for adjusting the height of the fluorescence detector 2, and the fluorescence detector 2 is disposed on the surface of the adjustment mechanism 4. The surface of the worktable 1 is provided with a shielding mechanism 5 for blocking external light sources. The top of the worktable 1 is provided with a dehumidifier 6 for reducing the humidity around the fluorescence detector 2. Specifically, the adjustment mechanism 4 and the shielding mechanism 5 are both controlled by the control box 7 to start and stop. The adjustment mechanism 4 can... The height of the fluorescence detector 2 can be adjusted to accommodate workers of various heights. The vertical plate 3 and the shielding mechanism 5 can shield the rear, top, and left and right sides of the fluorescence detector 2, thereby preventing light interference with the fluorescence signal of the fluorescence detector 2. The shielding mechanism 5 has an extension and retraction function. The dehumidifier 6 can control the humidity around the fluorescence detector 2, thereby preventing excessive humidity from affecting the quality and stability of the fluorescence probe on the fluorescence detector 2, and thus preventing humidity from affecting the detection results of the fluorescence detector 2. The above mechanisms can prevent light and excessive humidity from interfering with the fluorescence detector 2, thereby ensuring the accuracy of the fluorescence detector 2.
[0024] like Figure 1 , Figure 2 As shown, the adjustment mechanism 4 includes a guide rail 401. The top of the worktable 1 is fixedly provided with the guide rail 401, and the top of the guide rail 401 is fixedly provided with a first motor 402. The inner wall of the guide rail 401 is rotatably provided with a lead screw 403, and the top end of the lead screw 403 passes through the surface of the guide rail 401 and is fixedly connected to the output end of the first motor 402. The surface of the lead screw 403 is threadedly connected with a movable block 404, and the movable block 404 is slidably installed with the inner wall of the guide rail 401. The fluorescence detector 2 is fixedly installed on the surface of the movable block 404. Specifically, when the first motor 402 is started, its output end drives the lead screw 403 to rotate, thereby causing the movable block 404 to slide longitudinally, thereby realizing the height adjustment of the fluorescence detector 2.
[0025] like Figure 1 , Figure 3As shown, the blocking mechanism 5 includes a slide groove 501. The surface of the worktable 1 has the slide groove 501. A second motor 502 is fixedly mounted on the surface of the worktable 1. A bidirectional threaded rod 503 is rotatably mounted on the inner wall of the slide groove 501. One end of the bidirectional threaded rod 503 passes through the surface of the worktable 1 and is fixedly connected to the output end of the second motor 502. A slider 504 is threadedly connected to the surface of the bidirectional threaded rod 503, and the slider 504 is slidably installed against the inner wall of the slide groove 501. A rack 505 is fixedly mounted on the surface of the slider 504. A fixing block 506 is fixedly mounted on the surface of the worktable 1. A rotating shaft 507 is rotatably mounted on the surface of the fixing block 506. A shielding plate 508 is provided, and a gear 509 is fixedly sleeved on the surface of the rotating shaft 507, with the gear 509 meshing with the rack 505. A slot 510 is opened on the surface of the shielding plate 508, and the slot 510 is adapted to the first motor 402. Specifically, when the second motor 502 is started, its output end drives the bidirectional threaded rod 503 to rotate, thereby causing the slider 504 to slide horizontally, which in turn causes the rack 505 to move horizontally. The movement of the rack 505 causes the gear 509 to rotate, which in turn causes the rotating shaft 507 to rotate, which in turn causes the shielding plate 508 to flip. When the shielding plate 508 flips and blocks one side of the fluorescence detector 2, the slot 510 can prevent the first motor 402 from contacting the shielding plate 508.
[0026] like Figure 1 , Figure 3 As shown, the slider 504, rack 505, rotating shaft 507, shielding plate 508 and gear 509 are all provided in two sets, and the two sets of shielding plates 508 are arranged in a corresponding manner; specifically, the rotation of the bidirectional threaded rod 503 causes the two sets of sliders 504 to slide in opposite directions, thereby causing the two sets of racks 505 to move in opposite directions, which in turn causes the two sets of gears 509 to rotate in opposite directions, and the two sets of shielding plates 508 to flip over, thereby blocking the left and right sides of the fluorescence detector 2.
[0027] like Figure 1 , Figure 3 As shown, the slot 510 has two sets, and both sets of slots 510 are semi-circular. Specifically, when the two sets of baffles 508 are in contact, the two sets of slots 510 can form a complete circle, and at this time the first motor 402 is located between the two sets of slots 510.
[0028] like Figure 1 , Figure 3 As shown, both sets of shielding plates 508 are L-shaped and are adapted to the vertical plate 3. Specifically, when the two sets of shielding plates 508 are closed, the top of the two sets of shielding plates 508 can shield the top of the fluorescence detector 2, and the vertical plate 3 can shield the rear side of the fluorescence detector 2, thereby forming a semi-enclosed space.
[0029] In summary: Both the adjustment mechanism 4 and the shielding mechanism 5 are controlled by the control box 7. The adjustment mechanism 4 can adjust the height of the fluorescence detector 2 to accommodate workers of various heights. The vertical plate 3 and the shielding mechanism 5 can shield the rear, top, and left and right sides of the fluorescence detector 2, thereby preventing light interference with the fluorescence signal of the fluorescence detector 2. The shielding mechanism 5 has an extension and retraction function. The dehumidifier 6 can control the humidity around the fluorescence detector 2, thereby preventing excessive humidity from affecting the quality and stability of the fluorescence probe on the fluorescence detector 2, and thus preventing humidity from affecting the detection results of the fluorescence detector 2. The above mechanisms can prevent light and excessive humidity from interfering with the fluorescence detector 2, thereby ensuring the accuracy of the fluorescence detector 2.
