The inner wall of the limiting tube 21 is symmetrically provided with a moving groove 211, and one end of the moving groove 211 is provided with a limiting groove 212. The ventilation pipe mechanism 3 includes a gas pipe 31, an assembly pipe 32 and two limiting plates 34. One end of the assembly pipe 32 is welded to one end of the gas pipe 31, and the other end of the assembly pipe 32 is plugged into the fixed pipe 213 through a slot 217. The outer wall of the gas pipe 31 fits the outer wall of the sealing ring 216. The outer edge of the gas pipe 31 is symmetrically welded with a convex plate 33. The top of the convex plate 33 is fixedly connected with a spring 36, and the convex plate 33 is symmetrically welded with a convex plate 33. Slide grooves 37 are symmetrically provided on both sides of the plate 33, and sliders 35 are symmetrically fixedly connected to the two ends of the limit plate 34. The two ends of the limit plate 34 are slidably connected to the slide grooves 37 through the sliders 35. The top of the spring 36 is fixedly connected to the bottom of the limit plate 34, and one end of the limit plate 34 is plugged into one end of the limit groove 212.

Figure 6As shown, one end of the limiting plate 34 is a smooth arc. When the assembly pipe 32 enters the limiting pipe 21 along the moving groove 211, the limiting plate 34 is squeezed and moves along the sliding groove 37 toward the direction of the spring 36. At this time, the spring 36 is in a squeezed state. After the limiting plate 34 slides along the sliding groove 37, the limiting plate 34 is flush with the convex plate 33. The assembly pipe 32 passes through the limiting pipe 21 and enters the anti-leakage pipe 23. The assembly pipe 32 and the gas pipe 31 are continuously pushed until one end of the assembly pipe 32 is inserted into the slot 217. At this time, the convex plate 33 and the limiting plate 34 are completely moved out of the moving groove 211. The limiting plate 34 automatically rebounds to its original position under the action of the spring 36. At this time, one end of the limiting plate 34 is inserted into the limiting groove 212, thereby automatically limiting the assembly pipe 32 and the gas pipe 31 to prevent the assembly pipe 32 from moving. After the pipeline 32 to be assembled is plugged and fixed with the slot 217, the sample to be tested can be placed in the test box 11, and the gas corrosion test is controlled by the operation panel 12 and the control panel 13. Various gases are first configured to the required concentration according to the requirements, and then come out of the cylinders and are decompressed, and then enter the gas pipeline 31 through the control of the corrosion-resistant solenoid valve. The gas passes through the gas pipeline 31 and the assembly pipeline 32 in turn to reach the fixed pipe 213, and then enters the test box 11 through the through hole 215, the connecting pipe 1 25, the flow meter 26, the connecting pipe 2 27 and the connecting end 19, and then enters the diversion pipe at the bottom of the test box 11 together with the temperature and humidity air in the air-conditioning cabinet, and passes through the box body evenly, so as to perform a gas corrosion test on the sample; Through the cooperation of the limiting plate 34, the limiting groove 212 and the limiting tube 21, the gas pipeline 31 and the assembly pipeline 32 can be limited and fixed to prevent the assembly pipeline 32 from deflecting or sliding, so that the assembly pipeline 32 and the slot 217 are firmly plugged and fixed to prevent the assembly pipeline 32 and the slot 217 from loosening or falling off, and to prevent the device from being hit and causing the pipeline to loosen or fall off; at the same time, when one end of the assembly pipeline 32 passes through the connecting hole 214 and is plugged into the slot 217, the outer wall of the assembly pipeline 32 and the sealing ring 216 are squeezed and tightly fitted against each other, and one end of the assembly pipeline 32 is tightly pressed against the silicone rubber sealing ring 218, and the silicone rubber sealing ring 218 and the sealing ring 216 both achieve the strong sealing effect of corrosion-resistant silicone rubber, effectively preventing gas leakage and avoiding affecting the test results and corrosion. Other equipment in the room can be protected, while avoiding harm to the test operators; in addition, an anti-leakage tube 23 and a micro-exhaust fan 28 are added to the outside of the fixed tube 213. The anti-leakage tube 23 can protect the connection between the assembly pipe 32 and the fixed pipe 213, and reduce the looseness caused by collision. The micro-exhaust fan 28 can be turned on by the controller 22. The micro-exhaust fan 28 draws the gas in the anti-leakage tube 23 outward, so that the anti-leakage tube 23 always maintains a micro-negative pressure state, improves the sealing between the sealing ring 216 and the gas pipeline 31, and avoids the gas in the anti-leakage tube 23 from leaking outward, thereby solving the problem that the connection between the ventilation pipeline mechanism 3 and the box pipeline interface is easily deformed, loosened or has gaps due to collision, avoids gas leakage, and improves the safety of the device.
