Description

Technical Field

[0001] This utility model relates to the field of sampling mechanism technology, specifically to a sampling mechanism for fingerprint-resistant nano-liquid. Background Technology

[0002] During the production process of anti-fingerprint nano solution, the sampling mechanism can take samples from products of different batches and production times. By testing various performance indicators of the samples, such as particle size distribution and component content, the quality stability and consistency of the products can be evaluated to ensure that each batch of nano solution can meet the expected quality standards. Generally, the piston is pushed manually or automatically to create negative pressure in the cylinder, thereby drawing the anti-fingerprint nano solution into the cylinder to complete the sampling.

[0003] The existing technology has the following problems:

[0004] Existing devices cannot clamp and limit the sample tube during sampling. When the sampling mechanism cannot clamp and limit the sample tube, the sample tube is easily displaced due to slight external vibrations or the movement of the sampling mechanism itself. The movement of the sample tube without clamping and limiting causes changes in the relative position of the liquid surface and the sampling pipette, affecting the accuracy of sampling. In addition, existing devices cannot seal the gap between the sample tube and the sampling mechanism. When the gap between the sampling mechanism and the sample tube cannot be sealed, dust, impurities, and other particles from the external environment can easily enter the sample tube. For samples with high purity requirements, such as anti-fingerprint nano-liquids, even tiny dust particles can have a significant impact on their performance. At the same time, it will also affect the negative pressure inside the device and reduce the liquid extraction efficiency of the device. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0023] like Figure 1As shown, this utility model provides a sampling mechanism for anti-fingerprint nano-liquid, including a base 1, a sample storage tank 2 fixedly connected to the rear side of the base 1, an air extraction pipe 3 fixedly connected to the upper side of the sample storage tank 2, an inlet pipe 4 fixedly connected to the upper side of the sample storage tank 2, a corrugated pipe 5 fixedly connected to the other end of the inlet pipe 4, a slide 6 fixedly connected to the rear side of the inner surface of the base 1, a lifting plate 7 slidably connected to the front side of the slide 6, the outer wall of the corrugated pipe 5 fixedly connected to the lifting plate 7, and a connecting pipe 5 fixedly connected to the lower side of the lifting plate 7. The connecting column 10 and the base 1 are fixedly connected to the lower inner surface of the base 1. The inner surface of the fixed column 8 is movably connected to the sample tube 9. In use, the air in the sample storage container 2 can be extracted through the air extraction pipe 3 to form a certain negative pressure, so that the nano solution can flow into the connecting column 10 through the liquid inlet pipe 4 and the corrugated pipe 5 and then into the sample tube 9 for sampling. The lifting plate 7 can slide on the slide table 6, thereby driving the connecting column 10 to move up and down, so as to adjust the relative position of the connecting column 10 and the sample tube 9 to meet different sampling needs.

[0024] like Figure 2-3 As shown, this utility model provides a technical solution: Preferably, a first threaded rod 12 is rotatably connected to the upper side of the connecting column 10, and a first knob 11 is fixedly connected to the upper end of the first threaded rod 12. The upper side of the lifting plate 7 is rotatably connected to the first knob 11. A lifting plate 13 is threadedly connected to the outer wall of the first threaded rod 12. U-shaped plates 14 are slidably connected to both sides of the connecting column 10. A pressing plate 16 is fixedly connected to the lower end of the U-shaped plate 14. A sealing ring 15 is fixedly connected to the lower side of the connecting column 10. A sample tube 9 is movably connected to the inner surface of the sealing ring 15. The outer wall of the sealing ring 15 is movably connected to the pressing plate 16. Openings 17 are provided on both the left and right sides of the lifting plate 13. Inclined grooves 18 are provided on both the front and rear sides of the inner surface of the openings 17. Limiting posts 19 are fixedly connected to both the front and rear sides of the upper end of the U-shaped plate 14. The outer wall of the limiting post 19 is slidably connected to the inclined groove 18. When it is necessary to seal the gap between the connecting post 10 and the sample tube 9, the first knob 11 is turned. The first knob 11 drives the first threaded rod 12 to rotate. Since the first threaded rod 12 is threadedly connected to the lifting plate 13, and the lifting plate 13 can only move up and down on the first threaded rod 12, when the lifting plate 13 moves upward, the inclined groove 18 in the opening 17 will interact with the limiting post 19, causing the limiting post 19 to slide along the inclined groove 18, thereby driving the U-shaped plate 14 to move inward. The extrusion plate 16 at the lower end of the U-shaped plate 14 will extrude the sealing ring 15, so that the sealing ring 15 is tightly attached to the outer wall of the sample tube 9, thereby sealing the gap between the connecting post 10 and the sample tube 9, preventing external dust, impurities, and other particles from entering the sample tube 9, and ensuring the purity of the sample.

[0025] like Figure 4-5As shown, this utility model provides a technical solution: Preferably, a second knob 22 is rotatably connected to the upper side of the fixed column 8, a second threaded rod 23 is fixedly connected to the lower side of the second knob 22, a lifting ring 20 is threadedly connected to the outer wall of the second threaded rod 23, a plurality of guide posts 21 are fixedly connected to the upper side of the inner wall of the fixed column 8, the outer wall of the guide posts 21 is slidably connected to the lifting ring 20, support plates 26 are fixedly connected to both the left and right ends of the upper side of the lifting ring 20, a rack 27 is fixedly connected to the left side of the support plate 26, a gear 28 is meshed with the left side of the rack 27, a third threaded rod 29 is fixedly connected to the front side of the gear 28, a connecting plate 25 is threadedly connected to the outer wall of the third threaded rod 29, the outer wall of the connecting plate 25 is slidably connected to the fixed column 8, an arc-shaped clamping plate 24 is fixedly connected to the end of the connecting plate 25 near the sample tube 9, the outer wall of the sample tube 9 is movably connected to the arc-shaped clamping plate 24, and when it is necessary to clamp and limit the sample tube 9, the rotation... The second knob 22 drives the second threaded rod 23 to rotate. Since the second threaded rod 23 is threadedly connected to the lifting ring 20, and the lifting ring 20 can only move up and down under the restriction of the guide post 21, the lifting ring 20 will move up and down. When the lifting ring 20 moves up and down, it will drive the support plate 26 and the rack 27 to move up and down. The rack 27 meshes with the gear 28, thereby driving the gear 28 to rotate. The rotation of the gear 28 will drive the third threaded rod 29 to rotate. The third threaded rod 29 is threadedly connected to the connecting plate 25, and the connecting plate 25 slides under the restriction of the fixed post 8. Therefore, the connecting plate 25 will move towards the sample tube 9. The arc-shaped clamping plate 24 on the connecting plate 25 will gradually approach and clamp the sample tube 9, limiting the sample tube 9 and ensuring that the sample tube 9 will not shake or shift during the sampling process. This ensures that the pipette for each sampling can be accurately inserted into the predetermined upper or lower layer position, ensuring that the sampling and analysis of each layer of components is more accurate.

[0026] The working principle of the sampling mechanism used for the anti-fingerprint nano solution will be explained in detail below.

[0027] like Figure 1-5As shown, when it is necessary to seal the gap between the connecting column 10 and the sample tube 9, the first knob 11 is rotated. The first knob 11 drives the first threaded rod 12 to rotate. Since the first threaded rod 12 is threadedly connected to the lifting plate 13, and the lifting plate 13 can only move up and down on the first threaded rod 12, when the lifting plate 13 moves upward, the inclined groove 18 in the opening 17 will interact with the limiting column 19, causing the limiting column 19 to slide along the inclined groove 18, thereby driving the U-shaped plate 14 to move inward. The extrusion plate 16 at the lower end of the U-shaped plate 14 will extrude the sealing ring 15, making the sealing ring 15 tightly fit against the outer wall of the sample tube 9, thereby sealing the gap between the connecting column 10 and the sample tube 9, preventing external dust, impurities, and other particles from entering the sample tube 9, and ensuring the purity of the sample. When it is necessary to clamp and limit the sample tube 9, the second knob 22 is rotated. The second knob 22 drives the second When the threaded rod 23 rotates, since the second threaded rod 23 is threadedly connected to the lifting ring 20, and the lifting ring 20 can only move up and down under the restriction of the guide post 21, the lifting ring 20 will move up and down. When the lifting ring 20 moves up and down, it will drive the support plate 26 and the rack 27 to move up and down. The rack 27 meshes with the gear 28, thereby driving the gear 28 to rotate. The rotation of the gear 28 will drive the third threaded rod 29 to rotate. The third threaded rod 29 is threadedly connected to the connecting plate 25, and the connecting plate 25 slides under the restriction of the fixed post 8, so the connecting plate 25 will move towards the sample tube 9. The arc-shaped clamping plate 24 on the connecting plate 25 will gradually approach and clamp the sample tube 9, limiting the sample tube 9 to ensure that the sample tube 9 will not shake or shift during the sampling process, so that the pipette for each sampling can be accurately inserted into the predetermined upper or lower layer position, ensuring that the sampling and analysis of each layer of components is more accurate.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
