[0002] Oil-based paint is a type of paint with drying oil as the main film-forming substance. The main types include clear oil, thick paint, oil-based mixed paint, oil-based anti-rust paint, putty, and paint putty. All oil-based paints sold on the market have testing standards. The oil-based paint testing standards are important because most paints contain formaldehyde and toxic and harmful substances. Using a sampling device to extract oil-based paint for testing is an important criterion for judging whether the oil-based paint is qualified.

[0003] For example, the utility model with authorization announcement number CN218584431U discloses an oily paint detection sampling device, which can sample and take out oily paint at different positions individually, or sample and take out oily paint at different positions in batches individually, thus facilitating the user's operation and sampling and detection of oily paint.

[0025] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0026] Example

[0027] Please refer to Figure 1-5 As shown, the utility model provides a technical solution: an oily paint detection sampling device;

[0028] The outer end of the sampling tube 1 is engraved with a capacity scale 4, and a pull-out rod 5 is installed in the sampling tube 1. A push plate 6 is fixedly installed on the right end of the pull-out rod 5, and a rubber plug 12 is fixedly installed on the left end of the pull-out rod 5. The outer end of the rubber plug 12 fits tightly on the inner surface of the sampling tube 1. The rubber plug 12 is arranged on the right side of the sealing disc 3. A mounting groove 13 is provided at the left end of the sampling tube 1, and a mounting ring 8 is threadedly connected to the inner end of the mounting groove 13, so that sampling is convenient and quick;

[0029] The left end of the sample holding tube 2 is integrally installed with a sampling port 7, the outer side of the left end of the sample holding tube 2 is fixedly installed with a mounting ring 8, and the right end of the sample holding tube 2 is fixedly installed with a mounting frame 9, which has a simple and practical structure;

[0030] A connecting rope 10 is fixedly installed at the left end of the plugging disc 3, and the left end of the connecting rope 10 is clamped and installed on the inner end of the mounting frame 9. A fixing piece 11 is fixedly installed at the left end of the connecting rope 10, and the fixing piece 11 plays a role in connecting and installing the plugging disc 3. The mounting frame 9 is a cross-shaped structure, and the outer end of the fixing piece 11 is attached to the outer surface of the mounting frame 9, which is convenient for taking out samples and cleaning the inside of the sampling device.

[0031] Specific working principle:

[0032] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, when the oil-based paint detection sampling device is used, the oil-based paint to be sampled is selected, the sampling port 7 on the lower side of the sampling tube 1 is inserted into the interior of the oil-based paint, and the required depth is selected for extraction. When extracting, the push plate 6 is pulled outward, and the push plate 6 drives the rubber plug 12 to move inside the sampling tube 1 through the pull rod 5 to extract the air inside the sampling tube 1. The push plate 6 is continued to be pulled, and under the action of pressure, the outer ring of the blocking disc 3 opens, so that negative pressure is formed inside the sample holding tube 2, and the oil-based paint enters the interior of the sample holding tube 2 through the sampling port 7. When the required amount is extracted, the rubber plug 12 is stopped from moving, and the blocking disc 3 returns to the original state and fits on the right end of the sample holding tube 2.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the sampling is completed and the sample needs to be taken out, the sampling port 7 is rotated to make the mounting ring 8 rotate inside the mounting groove 13 to remove the sample holding tube 2. Because the right end of the sample holding tube 2 is blocked by the blocking disc 3, the oily paint inside the sample holding tube 2 will not flow out due to the atmospheric pressure. Then the blocking disc 3 is pulled outward, the connecting rope 10 of the elastic material is stretched, and the right end of the sample holding tube 2 is opened. The absorbed oily paint can flow out from the sampling port 7 to obtain the extracted sample. At the same time, the removal of the sample holding tube 2 also facilitates the cleaning of the inside of the sample holding tube 2. The above completes a series of operations of the oily paint detection sampling device. The content not described in detail in this specification belongs to the prior art known to professional and technical personnel in this field.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
