Beschreibung
Zusammenfassung:	The utility model relates to a hole plugging device for detecting the air tightness of a support part. The hole plugging device comprises a sealing plug cover, a sealing rubber ring and a clamping screw sleeve, the sealing plug cover is of a disc structure, an annular groove and an internal thread matched with the clamping threaded sleeve are arranged on the inner side wall of a disc, and the annular groove is located at the position close to the bottom of the disc. The sealing rubber ring is mounted in the annular groove; the clamping screw sleeve is of a split structure and is composed of two parts which are symmetrically arranged, the outer wall of the clamping screw sleeve is provided with an external thread matched with the sealing plug cover, and the inner wall of the clamping screw sleeve is provided with an internal conical surface matched with the external conical surface of the detected support. The device is simple in structure and convenient to operate, and compared with a putty cover plate and a
