[0002] Oil product testing refers to the process of evaluating the physical and chemical properties of oil product samples through laboratory analysis and testing, assessing the quality, composition, purity of oil products, and whether they meet industry standards and requirements. Oil product testing can ensure product quality, and the results detected, inspected, and reported in the oil product testing work directly affect the quality and quality of the final product. The oil product testing work can provide timely and accurate information through the detection, inspection, and analysis of products, enabling the production equipment to operate in the best state. The acid value, acidity, and viscosity in oil products are all factors affecting quality, and accurate values of these can be obtained through the oil product testing work.

[0063] Working principle: The staff inserts the present utility model into the flask through the grip 12. The grip 12 is a rod-shaped structure with a hexagonal cross-section, which is convenient for the staff to hold and rotate the present utility model through the hexagonal grip 12, preventing the staff from accidentally dropping the present utility model. The outer surface of the rod 11 is threadedly connected to the threaded tube 13. Through the action of the thread on the outer surface of the screw rod 11, the threaded tube 13 can be moved up and down by rotating the threaded tube 13. The outer edge of the threaded tube 13 is a hexagonal structure, which is convenient for the staff to hold and rotate the threaded tube 13 through the hexagonal grip 12. The threaded tube 13 moves up and down by rotation, thereby driving the push block 14 to move up and down. The upper ring 31 and the lower ring 21 have the same size specifications, and the outer surface radius is smaller than the inner diameter of the narrow mouth of the round-bottom flask. The upper circular plate 32 and the lower circular plate 22 have the same size specifications and are both annular structures with a circular hole opened in the center. The spring 51 can support the upper circular plate 32. The screw rod 11 is located between the openings of the upper circular plate 32 and the lower circular plate 22. The spring 51 pushes the upper circular plate 32 away from the lower circular plate 22, so that the upper circular plate 32 and the lower circular plate 22 are separated from each other, thereby straightening the elastic strip 42, enabling the upper ring 31, the lower ring 21 and the elastic strip 42 to enter the round-bottom flask. At this time, rotating the threaded tube 13 compresses the spring, causing the upper and lower circular plates to approach each other, thereby opening the elastic strip 42, making the elastic strip 42 contact the inner wall of the bottom of the flask. The elastic strip 42 is a wire structure with nylon filaments sleeved on the outer surface, having relatively high elastic toughness and stable chemical properties, and can scrape off the residue after oil product testing on the inner wall of the round-bottom flask. At this time, rotating the device through the grip 12 can clean the inner wall of the flask, which is fast and convenient.
[0064] The above are only optional embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
