Automobile roof air channel air-tightness detection device

Abstract

The invention discloses an automobile roof air channel air-tightness detection device, which comprises a hollow-structure box body. The box body is internally provided with clear water. The top portion of the box body is provided with an opening; an outer wall at one side of the box body is connected with an air inlet pipe; the air inlet pipe is connected with an air pressure gauge through a rubber guide pipe; the rubber guide pipe is connected with a rubber pipe; and one end, away from the rubber guide pipe, of the rubber pipe is connected with a pressurization ball. An outer wall at the side, close to the air inlet pipe, of the box body is rotatably connected with a connection pipe; and the connection pipe is connected with the air inlet pipe. An inner wall at one side, away from the connection pipe, of the box body is rotatably connected with a connection rod; and one end, away from the inner wall of the box body, of the connection rod is sleeved by a plug member. The outer wall atthe side, close to the connection rod, of the box body is provided with a groove, and the groove is internally provided with a bearing. The device can test the air-tightness of an automobile roof airchannel, can observe each leakage place of the automobile roof air channel, and provides basis for improvement for production of the automobile roof air channel.

Description

technical field [0001] The invention relates to the technical field of airtightness detection devices, in particular to an airtightness detection device for an automobile roof air duct. Background technique [0002] The air-tightness test of the existing car roof air duct uses the blower device to connect the sealed box through the pipeline, connects the anemometer and the barometer to the sealed box, and judges the air tightness of the car roof air duct by the change of the air outlet wind speed and the barometer To provide an improved reference for the production of roof air ducts, but the existing detection devices cannot detect air leaks in the roof air ducts, and cannot provide detailed information on the various production steps of the roof air ducts. As a reference, and under the condition of air leakage of the existing detection device itself, it is impossible to judge whether the air duct of the car roof is well airtight.
