Description

Technical Field

[0001] The utility model relates to the field of sampling rods, in particular to a sampling detection rod for oil product testing. Background Art

[0002] Petroleum is a viscous, dark brown liquid known as the "blood of industry". Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is one of the main objects of geological exploration. There are two theories about the formation mechanism of petroleum: biological sedimentation oil and petrochemical oil. The former is more widely accepted. It believes that petroleum is formed by organisms in ancient oceans or lakes after a long evolution. It is a biological sedimentation oil and is non-renewable. The latter believes that petroleum is generated by carbon in the crust itself, has nothing to do with organisms, and is renewable. Petroleum is mainly used as fuel and gasoline, and is also the raw material for many chemical industrial products, such as solutions, fertilizers, pesticides and plastics.

[0003] Before oil is mined, the components in the oil must be tested first, so that the corresponding mining plan can be formulated based on the test results. Before oil testing, staff must bring test sticks to the site for sampling operations.

[0004] The existing detection rod has sampling chambers at different depths of the rod body. After the sampling rod is inserted into the oil, the door of the sampling chamber is manually opened to allow the oil to automatically flow into the sampling chamber, and then the door of the sampling chamber is closed, which is relatively inconvenient to use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sampling detection rod for oil testing, comprising a handle, the bottom end of the handle is internally slidably connected to an intermediate section with one end extending from the bottom end of the handle, the intermediate section is internally slidably connected to an end section with one end extending from the bottom end of the intermediate section, the bottom ends of the intermediate section and the end section are both internally provided with a material storage cavity, and the outer bottom ends of the intermediate section and the end section are both slidably connected to a closed door that cooperates with the material storage cavity, the intermediate section and the end section are both slidably sleeved with a sliding strip connected to the closed door, and the inner wall of the handle and the inner wall of the intermediate section are both provided with a sliding groove that cooperates with the corresponding sliding strip, and the handle is internally provided with an extending device that cooperates with the end section.

[0007] The utility model is further configured such that the extending device includes a screw, a sliding rod and a rotating block, the top end of the end section is rotatably connected to a screw that passes through the middle section and is threadedly connected to the handle, the top end of the handle is rotatably connected to a rotating block, and the middle of the rotating block is connected to a sliding rod that is slidably connected to the screw.

[0008] The present invention is further configured such that the cross section of the slide rod is a regular polygon, the bottom surface of the rotating block is provided with an annular slider that cooperates with the handle, and the cross section of the annular slider is T-shaped.

[0009] The utility model is further configured such that a return spring is provided at the inner bottom end of the slide groove, and a convex block cooperating with the return spring is provided at the top end of the side surface of the slide bar.

[0010] The present invention is further configured such that the bottom surface of the end section is provided with a pointed head.

[0011] In summary, the present invention has the following beneficial effects:

[0012] The utility model arranges multiple retractable middle sections and end sections under the handle, and arranges sliding bars that cooperate with the closed door on the middle sections and the end sections. When the middle sections and the end sections are fully extended, the slide groove opens the closed door by restricting the sliding bar. At this time, the middle section and the end section are at sampling points at different depths, so that liquid substances at different depths can be sampled, which is more convenient to use.

When in use, the end section 3 and the intermediate section 2 are pushed out and extended by rotating the extension device. The bottom ends of the intermediate section 2 and the end section 3 are both provided with a storage cavity 5, and the outer bottom ends of the intermediate section 2 and the end section 3 are both slidably connected to a closed door 6 that cooperates with the storage cavity 5. The outside of the intermediate section 2 and the end section 3 are both slidably sleeved with a slide bar 7 connected to the closed door 6, and the inner wall of the handle 1 is connected to the The inner wall of the middle section 2 is provided with a slide groove 8 that cooperates with the corresponding slide bar 7. When the middle section 2 and the end section 3 are extended to near the limit, the slide groove 8 limits the movement of the slide bar 7. The middle section 2 and the end section 3 continue to move until they move to the limit, and the closed door 6 does not continue to move, so that the storage chamber 5 can be opened and the liquid can flow in. A return spring 9 is provided at the bottom end of the inner part of the slide groove 8, and a convex block that cooperates with the return spring 9 is provided at the top end of the side of the slide bar 7. After the sampling is completed, the extending device is rotated in the opposite direction to drive the end section 3 and the middle section 2 to retract.
