Abstract
Description
Technical Field
[0001] This utility model relates to the field of immunochromatographic test strip preparation technology, and in particular to a fluorescent quantitative test strip card assembly device. Background Technology
[0002] Immunochromatographic test strips have advantages such as high sensitivity and strong specificity, enabling rapid on-site detection. With the development of labeled solid-phase material technology, they can also achieve quantitative detection and multiplex detection, showing promising application prospects.
[0003] For example, Chinese utility model patent CN220019604U discloses a mounting plate assembly device for fluorescent quantitative test strips, including a substrate, a positioning plate and a sliding plate on the substrate, a placement groove for placing reagent plates is formed between the positioning plate and the sliding plate and the substrate, a pressure plate for pressing the reagent plates is detachably provided on the upper side of the placement groove, one side of the pressure plate abuts against the sliding plate, and the sliding plate can move back and forth relative to the positioning plate to position reagent plates of different sizes.
[0004] In the above solution, although the positioning plate and sliding plate can be used to accommodate test strip cards of different sizes for plate assembly, the sliding plate can only move back and forth in the vertical direction, which means that the equipment can only position test strip cards of different widths. Utility Model Content
[0005] To address the technical problem in the above solutions where the sliding plate can only move back and forth in the vertical direction, thus limiting the device to positioning test strips of different widths, this invention provides a fluorescent quantitative detection test strip assembly device.
[0006] This utility model is achieved using the following technical solution: a fluorescent quantitative test strip card assembly device, comprising a fixed box, a base fixedly connected to the top center of the fixed box, a test strip card placed on the top of the base, and limiting plates for clamping the test strip card provided on the top of the fixed box and on all four sides of the base, an electric push rod fixedly connected to the bottom inside the fixed box, a fixed block fixedly connected to the output end of the electric push rod, and connecting rods for moving the limiting plates abutting on the four outer sides of the fixed block.
[0007] Through the above technical solution, the electric push rod fixed to the bottom of the fixed box drives the fixed block to move upward, so that the connecting rod that abuts against the four sides of the fixed block can move to the outside of the fixed box, and drive the limiting plates on the four sides of the base to move to the outside of the fixed box at the same time, so as to facilitate the placement of test paper cards of different sizes on the base.
[0008] As a further improvement to the above solution, the fixing block is configured as a cone with inclined surfaces on all four sides, and an abutting ball is fixed to one end of the connecting rod near the fixing block, the abutting ball abutting against the inclined surface of the fixing block.
[0009] With the above technical solution, the fixing block is set as a cone with inclined surfaces on all four sides, and the fixing block moves upward with the electric push rod, so that the contact ball slides from the top of the inclined surface of the fixing block to the bottom, thereby driving the limiting plate fixed at the top of the connecting rod to move synchronously to the outside of the fixing box.
[0010] As a further improvement to the above solution, the top of the fixed box is provided with an opening for the movement of the limiting plate, and the bottom end of the limiting plate is fixed to the outside of the connecting rod.
[0011] As a further improvement to the above solution, a limiting post is fixedly connected inside the opening, and the limiting plate slides on the outside of the limiting post.
[0012] Through the above technical solution, the setting of the limiting post allows the limiting plate to move horizontally stably inside the opening, avoiding uneven force on the upper and lower ends of the limiting plate.
[0013] As a further improvement to the above solution, a connecting block is fixedly connected to the top of the inside of the fixed box, the connecting rod is slidably connected to the connecting block, and openings for the sliding of the connecting rod are provided on all four sides of the fixed box. An elastic component is provided between the connecting block and the limiting plate.
[0014] As a further improvement to the above solution, the elastic component includes a return spring, which is fixed between the connecting block and the limiting plate on opposite sides, and the return spring is located on the outside of the connecting rod.
[0015] Through the above technical solution, the setting of the reset spring in the elastic component can, on the one hand, enable the limiting plates on the four sides of the base to adaptively limit and fix test paper cards of different sizes to ensure that no displacement occurs; on the other hand, when the equipment completes the assembly of the test paper cards, it can allow the limiting plates to reset to the initial position.
[0016] As a further improvement to the above solution, a slot is provided on the vertical parallel side of the limiting plate near the base, and a card plate that engages with the slot is installed on the outside of the test paper card.
[0017] By using the above technical solution, a card plate is installed on the test strip card and the card plate is engaged in the slot opened in the limiting plate, which allows the test strip card to be assembled better and avoids poor adhesion of the test strip card edges.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] This invention, through the setting of a reset spring in the elastic component, enables the limiting plates on the four sides of the base to adaptively limit and fix test strip cards of different sizes, ensuring that no displacement occurs. On the other hand, when the equipment completes the assembly of the test strip cards, it can allow the limiting plates to return to their initial positions. Attached Figure Description

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Please combine Figures 1-4 This embodiment of a fluorescence quantitative test strip assembly device includes a fixed box 1, a base platform 2 fixedly connected to the top center of the fixed box 1, a test strip 3 placed on the top of the base platform 2, and limiting plates 4 for clamping the test strip 3 on the top of the fixed box 1 and on all four sides of the base platform 2. An electric push rod 5 is fixedly connected to the bottom inside the fixed box 1, and a fixing block 6 is fixedly connected to the output end of the electric push rod 5. Connecting rods 7 for moving the limiting plates 4 are abutted on the four outer sides of the fixing block 6.
[0028] Combination Figure 2 and Figure 4 The fixing block 6 is a cone with inclined surfaces on all four sides. The connecting rod 7 is fixed to one end near the fixing block 6 with an abutting ball 8, which abuts against the inclined surface of the fixing block 6.
[0029] By setting the fixing block 6 as a cone with inclined surfaces on all four sides, and moving the fixing block 6 upward with the electric push rod 5, the contact ball 8 slides from the top of the inclined surface of the fixing block 6 to the bottom, thereby driving the limiting plate 4 fixed to the top of the connecting rod 7 to move synchronously to the outside of the fixing box 1.
[0030] Combination Figure 4 The top of the fixed box 1 has an opening 9 for the movement of the limiting plate 4. The bottom end of the limiting plate 4 is fixed to the outside of the connecting rod 7. A limiting post 10 is fixed inside the opening 9. The limiting plate 4 slides on the outside of the limiting post 10.
[0031] By setting the limiting post 10, when the limiting plate 4 moves with the connecting rod 7, the limiting plate 4 will slide synchronously on the outside of the limiting post 10 fixed inside the opening 9, which allows the limiting plate 4 to move horizontally stably inside the opening 9, avoiding uneven force on the upper and lower ends of the limiting plate 4.
[0032] Combination Figure 2 and Figure 4 A connecting block 11 is fixedly connected to the top of the inside of the fixed box 1. The connecting rod 7 is slidably connected to the connecting block 11. Openings 12 for sliding of the connecting rod 7 are provided on all four sides of the fixed box 1. An elastic component is provided between the connecting block 11 and the limiting plate 4. The elastic component includes a return spring 13, which is fixedly connected between the connecting block 11 and the opposite sides of the limiting plate 4, and the return spring 13 is located on the outside of the connecting rod 7.
[0033] By setting the return spring 13 in the elastic component, during the sliding process of the contact ball 8 from the top to the bottom of the inclined surface of the fixed block 6, a certain distance of lateral horizontal displacement will be generated, which will drive the connecting rod 7 to move synchronously to the outside of the fixed box 1. This allows the connecting rod 7 to slide through the opening 12 on the connecting block 11 and the outside of the fixed box 1, and compress the return spring 13 between the limiting plate 4 and the connecting block 11. This causes the limiting plate 4, which is fixed to the top of the outside of the connecting rod 7, to move to the outside of the fixed box 1 within the opening 9. On the one hand, this allows the limiting plates 4 on the four sides of the base platform 2 to adaptively limit and fix test paper cards 3 of different sizes, ensuring that no displacement occurs. On the other hand, when the equipment completes the assembly of the test paper cards 3, it can allow the limiting plates 4 to return to the initial position.
[0034] The implementation principle of the fluorescent quantitative detection test strip card 3 assembly device in this application embodiment is as follows:
[0035] Before assembling the test strip card 3, the card plate 15 is installed on the four sides of the test strip card 3. At this time, the electric push rod 5 is turned on to drive the fixed block 6 with the inclined surface at the output end to move upward. Since the end of the connecting rod 7 is fixed with the abutting ball 8, and the initial position of the abutting ball 8 is in contact with the top of the inclined surface of the fixed block 6, the upward movement of the electric push rod 5 will cause the abutting ball 8 to slide from the top of the inclined surface of the fixed block 6 to the bottom. This will drive the limiting plate 4 fixed at the top of the connecting rod 7 to move synchronously to the outside of the fixed box 1 in the opening 9, and slide on the outside of the limiting post 10 inside the opening 9. At the same time, the horizontal movement of the connecting rod 7 will slide through the connecting block 11 and the opening 12, and compress the return spring 13 between the limiting plate 4 and the connecting block 11.
[0036] At this point, align the four sides of the test strip card 3 with the four limiting plates 4, and align the card plate 15 with the card slot 14. Then, activate the electric push rod 5 to move it downwards, causing the card plate 15 to engage in the card slot 14, thus assembling the test strip card 3.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
