[0029] Example 1:
[0030] A paint sampling device for testing includes a sampling cylinder 1 with a sampling port 4 fixedly connected to its bottom. Paint enters the sampling cylinder 1 through the sampling port 4. A top sleeve 5 is provided on the outer wall of the top of the sampling cylinder 1. A rotating groove is formed on the outer wall of the top sleeve 5, and a comparison frame 6 is fixedly connected to the inner wall of the rotating groove. By rotating a comparison ring 8, a comparison color block on its outer wall can be rotated into the comparison frame 6, facilitating comparison by the operator. The comparison ring 8 is slidably connected within the rotating groove, and multiple comparison color blocks, which are standard color samples, are provided on the outer wall of the comparison ring 8. An observation port 2 is provided on the outer wall of the sampling cylinder 1, and a glass is provided inside the observation port 2, allowing for easy comparison of the paint in the sampling cylinder 1 with the comparison color blocks. An indicator 3 is fixedly connected to the top of the observation port 2, allowing the operator to easily position the comparison color blocks. A fixing plate 7 is fixedly connected to the outer wall of the top sleeve 5, allowing the operator to easily push a fixing rod 9 downwards. Two support rods are fixedly connected to the top of the fixed rod 9, allowing workers to easily pull the fixed rod 9 upwards. The fixed rod 9 is slidably connected to the middle of the top of the top sleeve 5.
[0031] Example 2:
[0032] As one of the optimized structural designs for Example 1, such as Figures 1-4 As shown, the outer wall of the top of the sampling cylinder 1 and the inner wall of the top sleeve 5 are both provided with matching threads 10. The threads 10 allow the top sleeve 5 to be installed on the top of the sampling cylinder 1 or removed from the top of the sampling cylinder 1, facilitating the installation of the cleaning head 12 onto the bottom of the fixing rod 9. Afterwards, the sampling cylinder 1 is placed in water, and the cleaning head 12 is pulled along the fixing rod 9 to clean the inner wall of the sampling cylinder 1. A piston head 11 or a cleaning head 12 is movably installed at the bottom of the fixing rod 9. The piston head 11 allows the worker to easily draw paint into the sampling cylinder 1, while the cleaning head 12 facilitates the worker to clean the inner wall of the sampling cylinder 1, thus preventing paint residue from remaining inside the sampling cylinder 1.
[0033] Working principle: First, the sampling cylinder 1 is inserted into the paint. By pulling the fixing rod 9 upward, the fixing rod 9 moves the piston head 11 upward, so that the paint is drawn into the sampling cylinder 1 through the sampling port 4. Then, the sampling cylinder 1 is taken out. By rotating the contrast ring 8, the contrast color block on its outer wall is moved into the contrast frame 6, so that the staff can compare the paint with the contrast color block in the contrast frame 6 through the observation port 2. When it is necessary to clean the sampling cylinder 1, the top sleeve 5 is unscrewed from the top of the sampling cylinder 1, then the piston head 11 is taken out and unscrewed. After installing the cleaning head 12, the top sleeve 5 is installed on the top of the sampling cylinder 1. Then, the sampling cylinder 1 is put into water. By repeatedly pulling the fixing rod 9, the cleaning head 12 can be used to clean the inner wall of the sampling cylinder 1, so as to avoid paint residue in the sampling cylinder 1, which would cause the paint to mix and lead to inaccurate comparison results.
