[0002] At present, when the airtightness test is carried out to the automobile tailpipe, the automobile tailpipe is usually unloaded, one end of the automobile tailpipe is blocked with a sealing device, the other end of the tailpipe is sleeved with a leather tube, and then the whole device is placed Enter the water, blow air into the leather tube, and then observe whether there is gas released from the exhaust pipe of the car. Bubbles are generated, but often due to the poor airtightness of the socket of the leather tube and the exhaust pipe, the gas leaks from the interface between the exhaust pipe and the leather tube. Out of place, resulting in detection deviation, can not meet the needs of customers

The invention discloses a sealing property detection tool for an automobile tail gas tube. The tool comprises a fixing block, wherein a through hole is formed in the fixing block; a groove of which the cross section is arc-shaped is formed in the inner wall of the bottom side of the through hole; a rubber tube is arranged inside the groove; a tail gas tube is sleeved by the rubber tube; a throughhole is formed in the inner wall of the top side of the through hole; a sliding rod is mounted inside the through hole in the sliding manner; the bottom end of the sliding rod extends into the throughhole and is fixedly connected with a clamp head; the clamp head contacts the rubber tube; a threaded groove is formed in the top end of the sliding rod; a threaded block is mounted inside the threaded groove; a rotating rod is fixedly mounted on the top side of the threaded block; the top end of the rotating rod extends outside the through hole; a handle is fixedly mounted at the top end of the rotating rod; limiting grooves are formed in inner walls of both sides of the through hole; limiting blocks are fixedly mounted at two ends of the sliding rods. The tool is capable of tightly clampingan interface of the rubber tube and the tail gas tube and preventing a gas from leaking off from the interface to affect monitoring results, and is simple in structure and convenient to operate.
Description
technical field [0001] The invention relates to the technical field of airtightness detection, in particular to an airtightness inspection tool for automobile exhaust pipes. Background technique [0002] At present, when the airtightness test is carried out to the automobile tailpipe, the automobile tailpipe is usually unloaded, one end of the automobile tailpipe is blocked with a sealing device, the other end of the tailpipe is sleeved with a leather tube, and then the whole device is placed Enter the water, blow air into the leather tube, and then observe whether there is gas released from the exhaust pipe of the car. Bubbles are generated, but often due to the poor airtightness of the socket of the leather tube and the exhaust pipe, the gas leaks from the interface between the exhaust pipe and the leather tube. Out of place, resulting in detection deviation, can not meet the needs of customers. Contents of the invention [0003] The purpose of the present invention is ...
