[0023] During operation, after the container is produced or before the container is used, it is necessary to perform a sealing test on the inside of the container to ensure that the sealing of the container meets the requirements; when the above-mentioned container airtightness detection device is in use, it can only simply judge whether the sealing of the container is good, but cannot find the leakage position in time and accurately, and it takes a lot of time to check the containers one by one, resulting in a slow speed of subsequent maintenance operations.

With the cooperation of the moving mechanism 417, the structural box 1 moves to a suitable position, and the lifting device 415 is started again, so that the support block 3 descends and contacts the ground. After the inspection operation is completed, the power mechanism 413 is started, and the rotating rod 402 is rotated, so that the chain connecting member 403 is pulled into the interior of the winding chamber 2, and gradually wound on the outside of the rotating rod 402, which is convenient for the subsequent reuse of the inspection equipment.

[0026] Working principle: after the production of the container is completed or before the container is used, it is necessary to conduct a sealing test on the inside of the container to ensure that the sealing of the container meets the requirements; when the above-mentioned container airtightness detection device is in use, it can only simply judge whether the sealing of the container is good, but it is impossible to find the leakage location in time and accurately, and it takes a lot of time to check the containers one by one, resulting in a slow speed of subsequent maintenance operations. The present application operates through an auxiliary detection device, starts the lifting device 415 inside the installation slot 414, and the lifting rod 416 drives the moving mechanism 417 to move downward, and makes the structural box 1 drive the support block 3 to move upward a suitable distance.

Subsequently, the driving device 411 at the bottom of the fixed block 409 is turned on, and the moving device 412 operates to drive the connecting rod 410 and the chain connector 403 to move, so that the chain connector 403 passes through the structure The hole 401 is pulled out of the winding chamber 2, and the auxiliary support frame 418 is pulled out and in a vertical state, which ensures the horizontal operation of the chain connector 403, so that the operation range of the chain connector 403 can cover the surface to be detected of the container.
