Description

Technical Field

[0001] The utility model relates to the technical field of detection, in particular to an airtightness detection device. Background Art

[0002] In order to ensure the safe use of batteries, it is usually necessary to perform air tightness tests on the batteries. The usual method is to inflate the batteries and let them stand, and determine whether the battery is leaking by judging the drop in internal pressure of the battery. When the batteries are inflated and left standing, the batteries are usually placed directly on an operating table, and there is a lack of a fixing device for the batteries. Therefore, when inflating or leaving the batteries standing, accidental touches on the batteries will affect the air pressure inside the batteries, thereby causing deviations in the test results of the battery's air tightness.
