Description

Technical Field

[0001] The present invention relates to the field of protective clothing detection, and specifically to a detection system for special protective clothing with vital sign monitoring. Background Technique

[0002] Special protective clothing is a safety device for protecting and isolating the life safety of safety officers during disaster relief and rescue operations. Usually, a vital sign monitor is carried when entering and leaving dangerous areas to ensure the life safety of safety officers. When mass-producing special protective clothing, sampling detection is carried out on the special protective clothing, and the detection system mainly detects the airtightness of the protective clothing.

[0003] At the present stage, during the detection process of the detection system for special protective clothing, usually the upper side and the bottom side of the protective clothing are fixed, and then gas is filled into the protective clothing. During this process, it is observed whether the clothes leak air and whether they can withstand the force and cause rupture, and relevant detections are carried out through a rare gas detection device, which can detect the airtightness. However, in the actual use process, the clothes are not squeezed, and the detection effect is inaccurate in a flat state, and the detection cannot be adjusted according to different sizes of protective clothing. Summary of the Invention

[0004] The purpose of the present invention is to provide a detection system for special protective clothing with vital sign monitoring. The upper side of the clothes body is in contact with the connection plate, the spring rod is pushed by the force of the rotating disk to move the pressing plate downward, and cooperates with the rubber block to squeeze the collar of the clothes body, so as to form a seal. The clamping block cooperates with the restraint belt at the bottom side to limit the clothes body. The air pump inflates through the connection pipe to supply the clothes body, so that it is in a full state. The adjusting gear rotates, and the distance between the two pressing rollers changes to adapt to different protective clothing. By rotating the driving drive motor, the moving block moves up and down, which can make the pressing roller form friction with the clothes body, and is detected by a helium sensor, so as to detect the airtightness of the clothes body, so as to solve the problems raised in the above background technique.
