Fig. 4 is a schematic view illustrating a connection between a transition barrel cover and a barrel neck according to an embodiment of the present invention. As shown in fig. 4, when the first connecting section 131 is connected to the barrel neck 12, the second protrusion 1311 contacts the first protrusion 121, the first protrusion 121 is located between the second protrusion 1311 and the annular plate 132, and the other end of the barrel neck 12 abuts against the annular plate 132.

Through setting up staving, bucket neck, transition bung and sealed lid, the staving can be used to flourishing sample, and the bucket neck can be used to connect the transition bung, and sealed lid can be used to seal. The transitional barrel cover comprises a first connecting section, an annular plate and a second connecting section, the first connecting section and the second connecting section are respectively and coaxially connected to two sides of the annular plate, a plurality of first lugs are arranged on the outer wall of the barrel neck, a plurality of second lugs are arranged on the inner wall of the first connecting section, because the inner diameter of the first connecting section is larger than the outer diameter of the barrel neck, the first connecting section can be sleeved on the barrel neck when sampling is carried out, the second lugs are overlapped on the first lugs, a gap between the end part of the barrel neck and the annular plate, a gap between adjacent second lugs and a gap between adjacent first lugs form a channel for gas circulation together, a sealing cover connected with the second connecting section is disassembled when sampling is carried out, a sample enters the barrel body from the second connecting section, and gas can be discharged through the gap between the end part of the barrel neck and the annular plate, the gap between adjacent second lugs and the gap between adjacent first lugs, the sample splash is avoided being formed at the second connecting section, so that the sample splash when the sampling barrel is used for sampling is reduced. After sampling is completed, due to the fact that a gap for the first convex block to pass through is formed between the adjacent second convex blocks, the transition barrel cover can be rotated by a certain angle, the transition barrel cover is pressed downwards, the first convex block passes through the gap between the adjacent second convex blocks, the barrel neck abuts against the annular plate to form sealing, the transition barrel cover is rotated by a certain angle, the second convex block is in contact with the first convex block, the transition barrel cover is connected with the barrel neck, and the sealing cover is installed on the second connecting section, so that the sampling barrel is sealed.

Alternatively, the sealing cap 14 and the second connecting section 133 may be screw-coupled. The sealing cover 14 is conveniently taken down when sampling, and the sealing cover 14 is connected with the second connecting section 133 again after sampling is completed so as to seal the sampling barrel.

As shown in fig. 2, the first protrusion 121 has a first plane 121a, the first plane 121a is located on a side of the first protrusion 121 close to the barrel body 11, and an included angle between the first plane 121a and an axis of the barrel neck 12 may be an acute angle. As shown in fig. 3, the second protrusion 1311 has a second plane 1311a, the second plane 1311a is located on a side of the second protrusion 1311 close to the annular plate 132, and an angle between the second plane 1311a and an axis of the first connection segment 131 may be an acute angle. As shown in fig. 4, when the first connecting section 131 is connected to the barrel neck 12, the second plane 1311a is attached to the first plane 121 a. Thus, when the sampling barrel is closed, the transition barrel cover 13 is pressed downwards to make the barrel neck 12 abut against the annular plate 132, and then the transition barrel cover 13 is rotated, so that the first projection 121 and the second projection 1311 can be locked with each other through the first plane 121a and the second plane 1311 a.

Alternatively, the first plane 121a may be angled from 75 to 85 degrees from the axis of the barrel neck 12. The first plane 121a forms an acute angle with the axis of the barrel neck 12, and the acute angle is too small to facilitate the locking of the first protrusion 121 and the second protrusion 1311. Illustratively, the first plane 121a may be at an angle of 80 ° to the axis of the barrel neck 12, i.e., the first plane 121a may be at an angle of 10 ° to the cross-section of the barrel neck 12. Accordingly, the angle between the second plane 1311a and the axis of the first connection section 131 may be 75 ° to 85 °.

As shown in fig. 5, the second protrusion 1311 may overlap the first protrusion 121 during sampling, and the transition barrel cover 13 is prevented from rotating when the second connection segment 133 is aligned with the sampling cock of the christmas tree, so that the gap between the transition barrel cover 13 and the barrel neck 12 can be kept smooth to facilitate the gas discharge.

Illustratively, the barrel neck 12 may have 4 first protrusions 121 thereon, and the 4 first protrusions 121 are distributed at equal angular intervals. The first connection segment 131 may have 4 second protrusions 1311 thereon, and the 4 second protrusions 1311 are distributed at equal angular intervals.

Alternatively, the outer wall of the barrel neck 12 may have a plurality of friction protrusions 122, and the plurality of friction protrusions 122 are located between the first protrusion 121 and the end surface 12a of the barrel neck 12 far from the barrel body 11 in the axial direction of the barrel neck 12. In the sampling process, when the transition barrel cover 13 is rotated to enable the second bump 1311 to be overlapped on the first bump 121, the friction force between the second bump 1311 and the outer wall of the barrel neck 12 can be increased by the friction protrusion 122, so that the transition barrel cover 13 is not easy to rotate, the smoothness of the gap between the transition barrel cover 13 and the barrel neck 12 is kept, and the discharge of gas is facilitated.

Illustratively, the friction protrusions 122 may be ribs, bumps, knurls, or the like.

As shown in fig. 1, the surface of the annular plate 132 for abutment with the bung 12 may be provided with a sealing ring 134. Therefore, after sampling is finished, the sealing performance between the barrel neck 12 and the transition barrel cover 13 can be improved, and the leakage of the sample is avoided.

Alternatively, the first connection segment 131 may be a transparent structure, and the first and

second bumps

121 and 1311 may be non-transparent structures. The relative positions of the first bump 121 and the second bump 1311 can be observed through the first connecting section 131 during sampling, so that the second bump 1311 can be conveniently overlapped on the first bump 121, and the transition barrel cover 13 can be conveniently adjusted after sampling is completed, so that the first bump 121 is positioned between the second bump 1311 and the annular plate 132, and the first bump 121 and the second bump 1311 are locked.

Alternatively, the tub 11 may be a transparent structure. Therefore, the amount of the sample in the barrel body 11 can be observed conveniently, and the sampling is convenient.

As shown in FIG. 1, the outer wall of the tub 11 may further have an ear plate 111, and a handle 112 is connected to the ear plate 111. Therefore, the sampling barrel can be conveniently lifted and taken, the sampling can be carried and taken through the lifting handle 112 after the transition barrel cover 13 and the sealing cover 14 are sealed after the sampling is finished, and the sampling barrel is sent to a laboratory for testing.
