Referring to fig. 1, the embodiment of the present invention provides a sampling tube, which includes a tube body 110, an upper end cap 120 and a lower end cap 130.

Specifically, the tube body 110 has an upper end tube opening and a lower end tube opening, and the outer wall of the upper end tube opening is provided with a first annular bulge 113; the upper end cover 120 is arranged on the upper end pipe orifice, the inner wall of the upper end cover 120 is provided with a second annular bulge 121, and the first annular bulge 113 and the second annular bulge 121 are mutually meshed to achieve the sealing effect; the lower end cap 130 is mounted to the lower nozzle. The mutual occlusion of the second annular protrusion 121 of the upper end cover 120 and the first annular protrusion 113 of the outer wall of the pipe orifice of the upper end of the pipe body 110 is utilized to realize the quick sealing and fixing of the sampling pipe, the cover opening and closing efficiency of the sampling pipe is improved, and therefore the detection efficiency is improved.

Referring to fig. 2, a partition 111 is disposed in the tube body 110, the partition 111 divides the tube body 110 into a sample reserving cavity 200 and a sampling cavity 300, the upper end of the sample reserving cavity 200 is an opening, and the upper end nozzle is communicated with the lower end nozzle through the sampling cavity 300. The tube body 110 is divided into the sample reserving cavity 200 and the sampling cavity 300 by the partition 111, the height of the partition 111 is set according to the volume required for quantitative sampling of the sampling cavity 300, and the height of the partition 111 is changed to change the volume of quantitative sampling. When quantitative sampling is performed, the lower end cover 130 is opened to perform quantitative sampling of a sample, so that the volume measurement process of the sample is reduced, the efficiency of quantitative sampling is improved, and meanwhile, the sample in the sample retention cavity 200 can be retained for sample retention.

In the above embodiment, the first annular protrusion 113 of the upper nozzle and the second annular protrusion 121 of the inner wall of the upper cap 120 are engaged with each other to form a sealing ring, so as to achieve the function of sealing the upper nozzle in this embodiment. When the upper end cap 120 needs to be opened or closed, an external force is applied to the upper end cap 120, so that the upper end cap 120 can be opened or closed quickly. The sealing mode can be operated in batch, and the efficiency is far higher than that of the traditional spiral sealing mode. In this embodiment, the outer wall of the upper end pipe orifice of the pipe body 110 is uniformly provided with three first annular protrusions 113, the inner wall of the upper end cover 120 is provided with two second annular protrusions 121, the first annular protrusions 113 and the second annular protrusions 121 are mutually engaged to form two sealing rings, and the sealing effect of the upper end pipe orifice of the pipe body 110 is ensured.

In some embodiments, the inner wall of the upper nozzle has a tapered slope 112, and the tapered slope 112 gradually narrows from top to bottom toward the axis of the tube 110, as shown in fig. 2. Accordingly, the upper end cap 120 has a reverse tapered plug that conforms to the tapered ramp 112. When the upper end cover 120 needs to be opened or closed, an external force is applied to the upper end cover 120, so that the inverted conical plug and the second annular protrusion 121 of the upper end cover 120 are respectively engaged with the conical inclined surface 112 and the first annular protrusion 113 of the upper end nozzle of the tube body 110, and the effect of sealing the upper end nozzle of the sampling tube is achieved. The reliability of the connection of the upper end cap 120 and the upper end pipe orifice is improved by the mutual matching of the tapered inclined surface 112 and the inverted conical pipe plug. Meanwhile, the upper end pipe orifice is further sealed, and the condition that the sample leaks from the upper end pipe orifice is avoided.

As a modification of the above embodiment, the reverse tapered plug has a third annular protrusion 122, and the outer profile of the third annular protrusion 122 is adapted to the tapered slope 112 to achieve the sealing effect, as shown in fig. 3. The third annular protrusion 122 is disposed on the tapered inclined surface 112 to block the sample that may leak from the upper end pipe orifice, and the sample may flow back along the tapered inclined surface 112 into the test tube according to the embodiment of the present invention. The first annular bulge 113 on the outer wall of the upper end pipe orifice and the second annular bulge 121 on the inner wall of the upper end cover 120 are used as a first heavy sealing guarantee for the upper end pipe orifice of the sampling pipe in the embodiment of the utility model; the close contact between the third annular protrusion 122 on the inverted conical plug of the upper end cap 120 and the conical slope 112 serves as a second resealing guarantee for the upper nozzle, preventing the sample from leaking out of the upper nozzle. In addition, the mutual engagement between the first annular protrusion 113 and the second annular protrusion 121 also makes the connection between the upper cap 120 and the tube 110 more reliable and firm.

As another improvement of the above embodiment, the sampling tube further comprises a sealing device, which is disposed at the lower nozzle to store the sample in the sampling cavity 300. Further, the sealing means is an aluminum plastic film seal 115, and the sample is taken out from the sampling chamber 300 by puncturing the aluminum plastic film seal 115. When needs follow the utility model discloses during sampling pipe sample, just putting the sampling pipe of this embodiment, opening lower end cover 130, pierce aluminum-plastic film seal 115, then the sample in sample chamber 300 just flows out sample chamber 300, then closes lower end cover 130, and the sampling process is accomplished. Quantitative sampling of a sample is achieved by first placing a certain amount of the sample in the sampling cavity 300 of the sampling tube and then discharging the sample out of the sampling cavity 300. When the liquid level of the liquid sample in the sampling tube is lower than the partition 111, the sample on one side of the sample reserving cavity 200 can be poured into the sampling cavity 300 by inclining the tube body 110, so as to meet the sample requirement of quantitative sampling. As another improvement of the above embodiment, the lower nozzle is convex to avoid the situation that the plastic film seal is not tight or is damaged by overheating, as shown in fig. 2.

It should be noted that, in the embodiment of the present invention, the pipe body 110 includes a first section of pipe, a second section of pipe and a third section of pipe, the first section of pipe, the second section of pipe and the third short pipe are sequentially connected in series, and the lower end cap 130 is installed at a port of the third section of pipe. The diameter of the second section of pipe is smaller than that of the third section of pipe, so that the outer contour of the lower end of the pipe body 110 is in a convex shape.

The outer wall of the lower end nozzle is provided with a fourth annular protrusion 114, the inner wall of the lower end cover 130 is provided with a groove 131, and the groove 131 is matched with the protrusion to achieve the sealing effect, as shown in fig. 4.
