Abstract

The invention discloses an inflatable self-sealing device for detecting the air impermeability of an automobile pipeline. The inflatable self-sealing device comprises a main rod. A cavity is disposedat one end of the main rod. A sliding groove is formed in a side of the cavity. An annular groove is disposed on other end of the main rod along the sidewall of the main rod. An expandable airbag is disposed in the cavity. An annular airbag is disposed in the annular groove. A second through pipe is connected between the expandable airbag and the annular airbag. The expandable airbag is connectedto a first through pipe. The annular airbag is connected with a third through pipe. The diameters of the first through pipe, the second through pipe and the third through pipe are successively decreased. The main rod is in sliding connection with a slide block. The slide block is abutted against the expandable airbag and is connected with a connecting rod. The connecting rod is hinged to a fulcrumbar and is provided with a pressing block for tightly pressing a pipeline. The inflatable self-sealing device solves the problem that a rubber gasket used in pipeline sealing is liable to slip off.

Description

technical field [0001] The invention discloses a breathable self-sealing device for detecting the airtightness of automobile pipelines, and relates to the technical field of detection of automobile accessories. Background technique [0002] In the detection of various indicators of automobile pipelines, the detection of air tightness is very important. The quality of pipeline airtightness directly affects the normal use of various functions of automobiles and the performance of the whole vehicle. The air tightness detection of automobile pipelines At the same time, the seal at the interface directly affects the accuracy of detection. [0003] In the prior art, when testing the air tightness of automobile pipelines, it needs to be installed on the testing device, and then disassembled from the testing device after the test is completed. However, in the sealing of the pipeline, since the pipeline walls are all smooth surfaces, the testing device cannot be stable. It is fixed ...
