AI Technical Summary
Technical Problem
Existing airtightness testing methods cannot overcome the systematic errors caused by air leakage in the inflation equipment itself, resulting in inaccurate test results.
Method used
An airtightness testing fixture was designed. By establishing a pressure difference between the outer and inner sealed chambers, the colored test gas is observed through an observation window to ensure that leakage of the pressure difference generation device itself does not affect the test results.
Benefits of technology
It enables rapid and accurate detection of whether the seal under test is leaking, reduces system errors, and improves the accuracy and efficiency of detection.

Abstract
The utility model relates to an air tightness testing tool, which comprises an outer sealing box, an inner sealing box, a pressure difference manufacturing device and a to-be-tested sealing element, and is characterized in that the inner sealing box is arranged in an outer sealing cavity, and the to-be-tested sealing element penetrates through and is installed on the wall surface of the inner sealing box in a sealing manner; the pressure difference manufacturing device is installed on the wall face of the outer sealing box and can communicate with the outer sealing cavity, and the pressure difference manufacturing device can control the air pressure of the outer sealing cavity so that the air pressure difference can be formed between the outer sealing cavity and the inner sealing cavity. One of the outer sealing cavity and the inner sealing cavity with higher air pressure is defined as a high-pressure cavity, the other one is defined as a low-pressure cavity, the high-pressure cavity is filled with colored test gas, the air tightness test tool is provided with an observation window, and whether the test gas enters the low-pressure cavity or not can be observed through the observation window. According to the air tightness test tool provided by the invention, the problem that the detection result is inaccurate due to system errors caused by air leakage of inflation equipment cannot be overcome in an existing sealing detection mode is solved.
