Title:
PRESSING MECHANISM, GAS TIGHTNESS TEST PRESSING DEVICE, AND GAS TIGHTNESS TEST SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/007761
Kind Code:
A1
Abstract:
The present application relates to a pressing mechanism, a gas tightness test pressing device, and a gas tightness test system. At least two pressing structures are arranged on a bearing member, and the pressing structures are configured to be movable on the bearing member. In a test process, the pressing structures separately abut against a piece under test. If the surface of the piece under test is in an irregular or concave-convex shape or the like, by moving the pressing structures and changing the distance D between each pressing surface and the bearing member, each pressing surface can abut against the surface of the piece under test. After each pressing surface abuts against the surface of the piece under test, each pressing structure is locked by using a locking structure, so that a curved surface formed by assembling of the pressing surfaces is better fitted to the surface of the piece under test, thereby achieving effective profiling, and guaranteeing that the surface of the piece under test can be effectively pressed. In this way, in a gas tightness test process, the piece under test is not prone to structural deformation due to pressure difference between the inside and the outside. In addition, the compatibility is high, and the pressing requirements in tests in respect of different surface shapes are effectively met.
