[0053] Please refer to Figs. 1-3, in some embodiments, the gas sampling tube 10 includes a gas delivery tube 11, a gas sampling tube joint 12, and a joint lock 13. In the actual assembly process, first, one end of the gas delivery tube 11 is inserted through the through hole 131 of the joint lock 13, and then the gas delivery tube 11 is inserted into the first reverse buckle 121 and the first tube inlet 122. The first reverse buckle 121 can prevent the gas delivery tube 11 from being accidentally detached from the first tube inlet 122. A plurality of fixing members 132 provided on the joint lock 13 are used to firmly fix the gas delivery tube 11 in the first tube inlet 122. When the gas delivery tube 11 is inserted into the first tube inlet 122, the abutting boss 1231 below the first tube inlet 122 cooperates with the anti-blocking protrusion 1232 to form a clamping area, ensuring the stable positioning of the gas delivery tube 11 during assembly and preventing the gas delivery tube 11 from falling off or loosening. When the joint lock 13 is displaced downward and buckled into the clamping area, the fixing member 132 is expanded outward by the expansion part 1233, further ensuring the stable connection of the gas delivery tube 11. The extrusion buckle 1321, the deformation part 1322, and the buckle part 1323 are composed. The buckle part 1323 has an abutting segment 1324, a side supporting segment 1325, and a blocking segment 1326. When the joint lock 13 is buckled downward, the deformation part 1322 of the extrusion buckle 1321 is bent, and the abutting segment 1324 of the buckle part 1323 first contacts the expansion part 1233, causing the fixing member 132 to gradually expand. As the joint lock 13 continues to press down, the side supporting segment 1325 abuts against the side wall of the abutting boss 1231, providing additional support force and further enhancing the stability of the connection. Finally, the blocking segment 1326 enters the clamping area and is locked, firmly fixing the gas delivery tube 11 in the first reverse buckle 121 and the first tube inlet 122 of the gas sampling tube joint 12, and finally making the connection between the gas delivery tube 11 and the gas sampling tube joint 12 firm and not loose. In this way, the entire assembly process does not require the use of chemical adhesives, and after assembly is completed, the gas sampling tube 10 has good sealing performance, avoiding gas leakage, which not only simplifies the production process, but also significantly improves the safety and reliability of the product. The gas sampling tube 10 uses a mechanical connection method instead of the traditional glue curing process, fundamentally avoiding the release of volatile organic substances, improving the safety of the gas sampling tube 10, and using a mechanical connection process without the need for air drying and curing time, shortening the manufacturing time of the gas sampling tube 10 and improving the production capacity of the gas sampling tube 10.

The angle between the tangent of the expansion part 1233 and the axis of the gas sampling pipe joint 12 is set to 20°-80°. Specifically, the angle between the tangent of the expansion part 1233 and the axis of the gas sampling pipe joint 12 can be set to 20°, 30° or 80°, thereby ensuring that the fixing pieces 132 are uniformly stressed during expansion, avoiding stress concentration of the fixing pieces 132, and thereby avoiding the risk of damage and failure of the fixing pieces 132.

[0057] Please refer to FIG. 2 and FIG. 3, in some embodiments, the fixing pieces 132 each include a plurality of extrusion buckling pieces 1321, which are fixedly arranged on one end of the joint lock 13 away from the through hole 131. The extrusion buckling pieces 1321 each include a deformation part 1322 and a buckle part 1323. The deformation part 1322 is used to temporarily deform when the buckle part 1323 is subjected to external force, and returns to its original shape when not subjected to external force or when the external force disappears, thereby achieving better deformation and clamping effect of the joint lock 13 during the clamping-in process, and ensuring the stability and reliability of the connection between the joint lock 13 and the locking part 123.

[0058] Please refer to FIG. 4, in some embodiments, the buckle part 1323 is provided with an abutting segment 1324, a side supporting segment 1325 and a locking segment 1326; the abutting segment 1324, the side supporting segment 1325 and the locking segment 1326 are integrally formed, and the joint lock buckle 13 can be accurately clamped into the clamping area and a stable locking effect can be achieved through the synergistic effect of the abutting segment 1324, the side supporting segment 1325 and the locking segment 1326; the included angle between the tangent line of the abutting segment 1324 and the tangent line of the locking segment 1326 is 10°-90°, and the included angle between the tangent line of the abutting segment 1324 and the tangent line of the locking segment 1326 is specifically 10°, 60° or 90°, thereby realizing smooth transition of the buckle part 1323 from preliminary abutment to final locking, improving the accuracy and stability of the connection between the joint lock buckle 13 and the locking part 123, wherein the gas sampling tube 10 passes out of the through hole 131, the gas sampling tube 11 is sleeved in the first reverse buckle 121 and the first pipe inlet part 122, so that the joint lock buckle 13 is displaced towards the gas sampling tube joint 12, the abutting segment 1324 abuts against the expansion part 1233, the expansion part 1233 is expanded outward, driving the deformation part 1322 to bend, the side supporting segment 1325 abuts against the side wall of the abutting boss 1231, and the locking segment 1326 is locked in the clamping area, thereby realizing mechanical connection without using chemical adhesives during the entire assembly process, and after assembly, the gas sampling tube 10 has good sealing performance, avoiding gas leakage, which simplifies the production process and significantly improves the safety and reliability of the product, the gas sampling tube 10 uses mechanical connection instead of traditional glue curing process, which fundamentally avoids the release of volatile organic compounds, improves the safety of the gas sampling tube 10, and at the same time, the mechanical connection process does not require air drying and curing time, shortens the manufacturing time of the gas sampling tube 10, and improves the production capacity of the gas sampling tube 10.

[0059] In some embodiments, the joint lock buckle 13 further comprises a first ultrasonic line, which is arranged at one end of the joint lock buckle 13 away from the through hole 131, and is used for ultrasonic welding with the gas sampling tube joint 12, so that the contact surface between the joint lock buckle 13 and the gas sampling tube joint 12 is melted and recombined under high temperature and high pressure, forming a seamless connection, effectively improving the sealing performance of the connection and reducing the risk of gas leakage, at the same time, ultrasonic welding can be directly performed during the assembly process of the gas sampling tube 10, without additional glue curing time or UV irradiation, further simplifying the assembly process and improving the production efficiency of the gas sampling tube 10.

[0060] In some embodiments, the first ultrasonic line is arranged in a conical, triangular or tapered shape along the cross section of the joint lock 13 in the axial direction, thereby facilitating the propagation and focusing of ultrasonic waves during welding, improving the efficiency and quality of welding.

[0063] In some embodiments, the sharper the tip of the first ultrasonic line is, the better, thereby the vibration energy can be concentrated at the tip of the triangular shape, and then the accumulated heat can form a uniform plastic melt flow on the entire welding interface, improving the welding efficiency and quality, making the connection of the gas sampling pipe joint 12 and the joint lock 13 more stable, thereby abandoning the process of using glue to solidify, eliminating the safety risks caused by the volatilization of volatile organic substances, ensuring the safety of the user, and without the need for air drying and curing time, shortening the manufacturing time and cost of the gas sampling pipe 10, and improving the production capacity of the gas sampling pipe 10 product.

[0064] In some embodiments, the principle of the first ultrasonic linear welding is to use the high-frequency vibration of the welding head of the first ultrasonic linear to cause high-frequency friction between the contact surfaces of the gas sampling tube joint 12 and the joint lock 13, convert mechanical energy into heat energy, and dissolve the molecules of the welding surfaces of the gas sampling tube joint 12 and the joint lock 13 with heat energy to restore their activity. Then, with the assistance of external force, the molecules are intertwined with each other to achieve the purpose of welding, thereby greatly improving the gas sealing and welding quality between the gas sampling tube joint 12 and the joint lock 13, avoiding the loosening problem caused by traditional glue connection, abandoning the curing process using glue, eliminating the safety risk caused by the volatilization of volatile organic substances, ensuring the safety of the user, improving the safety of the equipment, and without the need for air drying curing time, shortening the manufacturing time and cost of the gas sampling tube 10, and improving the production capacity of the gas sampling tube 10 product.
