Description

Technical Field

[0001] The present application relates to the technical field of oil detection, and in particular to an easy-to-use oil detection sampling mechanism. Background Art

[0002] Oil is a general term for hydrophobic substances that are liquid at room temperature. It is composed of one or more liquid hydrocarbons (silicone oil is largely composed of silicon oxides). It differs from hydrocarbons such as alcohols, ketones and ethers in that the components of oil are not polarized, and it differs from fats in that the molecular length of the compounds that make up oil and the connections between the molecules are relatively small.

[0003] For example, announcement number CN208653864U proposes a sampling and detection device for petroleum oil products, in which a sealed tank body is set as a transfer station to hold the oil to be tested, and a winding wheel is installed at the top of the transfer tank through a double fork arm bracket. The middle part of the winding wheel is wound and connected to the oil guide hose, one end of the oil guide hose is connected to the oil suction nozzle and enters the inner cavity of the transfer tank from the detection opening. The winding wheel is driven by a lifting motor installed on one side of the winding wheel to drive the oil suction nozzle through the oil guide hose to suck oil at different depths of the transfer tank. The sucked oil is connected to the oil product holding dish through a rotating conduction joint, and an oil product detection probe is installed on one side of the oil product holding dish to detect the oil. However, during the use of this application, when sampling the oil, during the carrying process, because the oil delivery hose is long, even after being rolled up, the hose is not fixed, and it is easy to be scattered or dirty due to the elasticity of the oil delivery hose itself, which affects the oil detection sampling and brings inconvenience to the staff. Therefore, a convenient oil detection sampling mechanism is proposed to solve the above-mentioned problems. Utility Model Content

Then, the limiting plate 17 is driven to move upward by rotating the threaded rod 15, and the limiting plate 17 squeezes and limits the sampling hose 5, thereby reducing the scattered situation of the sampling hose 5, making it easier to carry the sampling hose 5 and convenient for users to use.

[0025] The working principle of the above embodiment is:

[0026] The convenient oil detection sampling mechanism, in the process of detecting and sampling the oil, by rotating the threaded rod 15, the guide rod 16 guides the limiting plate 17, drives the limiting plate 17 to move downward, so that the limiting plate 17 cancels the restriction on the sampling hose 5, and facilitates the sampling hose 5 to be removed from the outside of the winding roller 14, and then connects the sampling hose 5 with the connecting nozzle 4 on the sampling tube 1, and extends one end of the sampling hose 5 into the oil to be detected, and drives the piston 3 to move by starting the cylinder 2 to extract the oil, so that the oil enters the sampling tube 1, and then pulls the pull plate 11 drives the baffle 10 to move in the slide groove through the slider, so that the baffle 10 no longer blocks the inside of the connecting tube 7, and the oil in the sampling tube 1 enters the sampling bottle 8 through the connecting tube 7 to complete the sampling of the oil. After the sampling is completed, the pull plate 11 is released, and the tension of the spring 12 drives the baffle 10 to reset, and the baffle 10 blocks the connecting tube 7 to reduce the leakage of the oil in the sampling tube 1. In addition, after the oil sampling is completed, the sampling hose 5 is rewound on the outside of the winding roller 14 to facilitate the carrying of the sampling hose 5 and the use of the user.
