When the cabin member 5 is conveyed between the two groups of support plates 10, the detection component and the gas supply component are squeezed toward both ends of the cabin member 5 at the same time, and sealed with both ends of the cabin member 5. The gas supply component supplies gas to the inside of the cabin member 5 for pressurization, and the detection component detects the pressure change inside the cabin member 5, so as to judge the air tightness of the cabin member 5. The detection installation is simple and the sealing is guaranteed. After the detection is completed, the detection component and the gas supply component are away from the cabin member 5, so as to conduct a water-based detection of the air tightness of the cabin member 5, and the air tightness detection efficiency of the cabin member 5 is high.

[0026] The upper ends of the base 1 are fixedly connected to fixing frames 4 on both sides, the upper ends of the two sets of fixing frames 4 are fixedly connected to a frame 6, the lower end of the frame 6 is fixedly connected to a fixing assembly, and the lower end of the fixing assembly is squeezed and matched with the upper end of the surface of the through-chamber member 5.

[0027] like Figure 1As shown, when the cabin-through piece 5 is conveyed between the two groups of support plates 10, the fixing assembly squeezes and fits the upper end of the cabin-through piece 5 to fix the cabin-through piece 5 on the conveyor belt 2 to prevent the cabin-through piece 5 from moving.

[0028] The detection assembly includes a push rod 11, which is fixedly connected to the upper end of the support plate 10, and the output end of the push rod 11 is fixedly connected to a driving frame 12, and the end of the driving frame 12 is fixedly connected to a sealing plate 13, and the sealing plate 13 is sealedly abutted with one end of the through-chamber member 5, and a detection tube 17 is connected to the middle of the sealing plate 13, and a detection head 16 is fixedly connected to one end of the detection tube 17, and a push rod 14 is fixedly connected to the inner wall of the driving frame 12, and the other end of the detection tube 17 is fixedly connected to the output end of the push rod 14, and the side wall of the detection tube 17 is connected and fixedly connected with a connecting tube 18.

When the cabin member 5 is conveyed between the two groups of support plates 10, the detection component and the gas supply component are squeezed toward both ends of the cabin member 5 at the same time, and sealed with both ends of the cabin member 5. The gas supply component supplies gas to the inside of the cabin member 5 for pressurization, and the detection component detects the pressure change inside the cabin member 5, so as to judge the air tightness of the cabin member 5.
