[0002] PVC gloves are made primarily from polyvinyl chloride (PVC). They feature anti-static properties and are processed in a Class 1000 cleanroom, using high-purity water and ultrasonic cleaning. They are cleaned / processed / packaged / stored in a Class 1000 cleanroom. The gloves remain flat, free of color, impurities, and odor, ensuring uniform color and quality. Class 10000 PVC gloves are suitable for use in standard Class 10000 dust-free cleanrooms.

[0003] Publication No. CN217059173U discloses a PVC glove air-tightness tester, which relates to the field of glove technology. Addressing the inconvenience of existing PVC glove air-tightness testing, the following solution is proposed: a test platform with a rectangular slot defined on its upper side, an air inlet pipe located within the slot, and an air pump fixedly connected to its lower side. The lower end of the air inlet pipe extends through the test platform and is fixedly connected to the output of the air pump, while the upper end of the pipe extends outside the slot. This utility model boasts a simple structure and easy operation, allowing for quick installation and removal of PVC gloves, improving the efficiency of air-tightness testing. The provision of several pressure plates and sealing plates enhances the glove's sealing performance, preventing air leaks during testing that could lead to inaccurate test results.

[0004] This patent realizes the clamping of gloves during testing, which facilitates the subsequent air tightness testing of gloves. However, when in use, this patent adopts manual movement of the pull ring, and the movement of the pull ring can drive the movement of the clamping plate through mechanical transmission. In addition, when the gas is passed into the inside of the glove, the inspector's hand needs to keep the pull ring in place. This method increases the workload of the staff, and when the hand shakes or shakes, the position of the pull ring slides, which in turn reduces the clamping effect of the clamping plate, affecting the air tightness of the gloves during testing. For this purpose, a PVC glove air tightness testing fixture is provided. Utility Model Content
