Description

Technical Field

[0001] The utility model relates to the technical field of water-based paint detection, in particular to a water-based paint segmented sampling tube. Background Art

[0002] Water-based paint is a paint that uses water as a diluent and does not contain organic solvents. At the beginning, water-based paint was not recognized by the public, and people were always very skeptical about this new product. In the early days of use, manufacturers often added gasoline, xylene, banana water and other organic thinners to water-based paint, causing a lot of unnecessary trouble. During the production and processing of water-based paint, water-based paint needs to be sampled and tested in sections, so a water-based paint segmented sampling tube is needed.

[0003] After searching, the existing patent (publication number: CN218271562U) discloses a sampling device for paint detection, including an outer tube and a storage assembly, an end cover is installed on the top surface of the outer tube, a lower pressure rod is arranged on the inner bottom surface of the outer tube, and the inner surface of the outer tube is fixedly connected to the retaining ring, a spring is arranged on the outer surface of the lower pressure rod, the top surface of the lower pressure rod is fixedly connected to the sampling assembly, the center of the end cover is slidably connected to the upper pressure rod, the top surface of the upper pressure rod is fixedly connected to the pressing sheet, and a rectangular opening is opened on the outer surface of the outer tube. The utility model sets a plurality of sampling assemblies in the outer tube. When the sampling device is placed in the paint bucket, the upper pressure rod is driven by pressing the pressing sheet, the upper pressure rod drives the sampling assembly, and the sampling assembly drives the lower pressure rod, forcing the spring to contract until the inner tube at the bottom contacts the retaining ring. After a short period of rest, the paint enters the inlet from the rectangular opening and then enters the inner tube. The overall structure is convenient for sampling paint of different depths in the paint bucket, so that the sampling is very comprehensive and sufficient.

[0004] During use, the existing paint detection sampling device can sample paint at different depths in the paint bucket. However, during the sampling process, the paint may contain impurities, which may cause errors in the subsequent detection structure after the paint sample is taken out, resulting in inaccurate detection results. At the same time, the paint-contacting end of the sampling device may be corroded and damaged by the paint due to long-term contact with the paint, and the sampling end cannot be replaced, resulting in the entire sampling device being unusable.
