[0034] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0035] Reference Figures 1 to 6 As shown, an inert gas sampling container comprises a container body 1;

[0036] The container body 1 has an inner cavity, and the container body 1 is provided with an air pipe 11 communicating with the inner cavity, and the container body 1 is also provided with a pipe 12 communicating with the inner cavity;

[0037] The air pipe 11 is welded to the container body 1, and a joint 111 with a quick-release function is provided at one end of the air pipe 11 away from the container body 1. The pipe 12 is welded to the container body 1, and a pressure gauge displaying the pressure in the cavity is installed on the pipe 12;

[0038] The container body 1 is also provided with a handle 13 for conveniently lifting the container body 1 .

[0039] The pressure gauge is a common structure in the prior art.

[0040] The joint 111 should have good sealing properties to prevent gas leakage. For example, the joint 111 can be fixed to the gas pipe 11 by threaded connection, and the pressure gauge can be fixed to the pipe 12 by threaded connection. The pressure gauge is not shown in the figure.

[0041] Reference Figures 1 to 6 As shown, in some embodiments, the pipe fitting 12 includes a vertical portion 121 and a horizontal portion 122, the vertical portion 121 and the horizontal portion 122 have a smooth transition, the vertical portion 121 is welded to the container body 1, the vertical portion 121 and the horizontal portion 122 are an integrated structure, and the pressure gauge is installed on the horizontal portion 122.

[0042] The air pipe 11 includes a vertical portion 112 and a horizontal portion 113. The vertical portion 112 is arranged in parallel with the vertical portion 121, and the horizontal portion 113 is arranged in parallel with the horizontal portion 122. The vertical portion 112 is welded to the container body 1, and the joint 111 is installed on the horizontal portion 113. The horizontal portion 113 and the vertical portion 112 are an integrated structure, and the vertical portion 112 and the horizontal portion 113 have a smooth transition.

[0043] The pressure gauge and the joint 111 can be arranged relative to each other, or they can be arranged facing each other. Relative to each other means that the pressure gauge and the pipe joint 111 are in opposite directions, and facing each other means that the pressure gauge and the joint 111 are in the same direction. In actual application, the directions of the pressure gauge and the joint 111 can be reasonably set as needed.

[0044] The joint 111 is a common joint 111 in the prior art, and the joint 111 should have sealing performance to prevent gas leakage.

[0045] The horizontal portion 122 and the transverse portion 113 are provided to reduce the vertical height of the container body 1 so that the container body 1 occupies a smaller space, thereby making it easier for the joint 111 on the container body 1 to be connected to the sampling interface.

[0046] The air pipe 11, the pipe fitting 12 and the container body 1 can all be made of metal materials to prevent gas leakage.

[0047] At the same time, the container body 1 can have a thickness as small as possible, that is, the container body 1 can be set with a wall thickness as thin as possible under the premise of meeting the strength requirements, which is conducive to the subsequent analysis and detection of the gas.

[0048] Specific structural parameters of the container body 1 In the prior art, the container body 1 usually further includes a guide portion, which is used to guide the gas entering the container body 1 so that the gas is evenly distributed in the container body 1.

[0049] Reference Figures 1 to 6 As shown, in some embodiments, the transverse portion 113 and the horizontal portion 122 have the same height.

[0050] A clearance space is formed between the transverse portion 113 and the horizontal portion 122 , and the handle 13 is located in the clearance space.

[0051] The handle 13 is welded to the container body 1 .

[0052] The setting of the handle 13 makes the container body 1 easy to carry. Since the container body 1 needs to have a high sealing property to prevent gas leakage, the sealing property of the container body 1 should not be damaged when the handle 13 is fixed to the container body 1. The handle 13 is fixed to the container body 1 by welding, and the container body 1 will not be damaged, thereby improving the sealing property of the container body 1.

[0053] The pipe fitting 12 and the air pipe 11 are both welded to the container body 1 , and the connection between the pipe fitting 12 , the air pipe 11 and the container body 1 will not damage the container body 1 , so the container body 1 can maintain good sealing properties.

[0054] In some embodiments, a protective cover 2 is provided outside the container body 1 to protect the container body 1, the handle 13, the air pipe 11, the pipe fitting 12 and the pressure gauge are all located inside the protective cover 2, the protective cover 2 includes an upper half 21 and a lower half 22, the upper half 21 is threadedly mounted on the lower half 22, and the upper half 21 is provided with a handle 211 for facilitating lifting the protective cover 2.

[0055] The protective cover 2 is divided into an upper half 21 and a lower half 22. The lower half 22 does not need to be removed during the sampling process, that is, when the container body 1 is moved, the upper half 21 cooperates with the lower half 22, and the container body 1 and the related features installed on the container body 1 are all located inside the protective cover 2. At this time, the container body 1 will not be collided, so that when the container body 1 is moved, the container body 1 is not easily collided, and the container body 1 is not easily damaged.

[0056] When it is necessary to sample the inert gas, it is only necessary to open the upper half 21 to expose the joint 111 to the outside, and the container body 1 does not need to be separated from the lower half 22, that is, the container body 1 is still protected by the lower half 22 during the sampling process, so that the container body 1 is not easily collided, the container body 1 is not easily damaged, and the container body 1 is not easy to leak, thereby improving the safety of the inert gas sampling container.

[0057] In some embodiments, the lower half 22 includes an upper ring 221 and a bottom plate 222, a vertical rod 223 is arranged between the upper ring 221 and the bottom plate 222, the upper end of the vertical rod 223 is welded to the upper ring 221, the lower end of the vertical rod 223 is welded to the bottom plate 222, and the vertical rod 223 is evenly distributed between the upper ring 221 and the bottom plate 222.

[0058] The upper ring 221 contacts with the container body 1 , or may not contact with the container body 1 . The vertical rod 223 needs to contact with the container body 1 .

[0059] Two adjacent vertical rods 223 are arranged in parallel, an observation port is formed between the two adjacent vertical rods 223 , and a buffer layer is provided on the vertical rods 223 .

[0060] Two adjacent vertical rods 223 may also be arranged crosswise. The buffer layer is a layered structure that has a buffering function, and when the protective cover 2 is hit, it absorbs vibrations to prevent the container body 1 from being impacted, or to reduce the impact on the container body 1. The buffer layer may be a sponge layer or a rubber layer or other material with elastic deformation ability.

[0061] The upper ring 221 is provided with an external thread, and the upper half 21 is provided with an internal thread matching the external thread.

[0062] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.

[0063] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination, and various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments according to needs during specific implementation to obtain a better application experience.
