Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an inner hole rapid sealing unit. Background Art

[0002] Leak testing of parts is a common task in various industrial and laboratory environments. These tests usually require establishing a reliable seal on the port of a part or device for pressure or vacuum testing of gas or liquid. The current testing process faces the dual challenges of time efficiency and sealing quality, especially when a large number of test samples need to be processed.

[0003] Traditional sealing methods may involve manual installation and removal of seals, which is not only time-consuming and labor-intensive, but may also lead to inaccurate or inefficient testing. On the other hand, although some existing rapid sealing units can provide certain operational conveniences, they still have some limitations in terms of sealing performance, reliability, and rapid installation and removal.

[0004] Therefore, for applications that require efficient leakage testing, especially when the test volume is large and the test frequency is high, an inner hole rapid sealing unit is required that can quickly and reliably seal the port while ensuring the accuracy and efficiency of the test.
