SELF-LOCKING SEALING DEVICE |
摘要 |
A seal including a body (11) with a recess (8) at one end engageable by a spanner, and a screw thread (2) at the other end for engaging a complementary screw thread (7) in an opening (6) of a housing (3). A locking ring (31) biased by a spring in the seal (1) and a complementary locking ring (47) in said opening have asymmetrical teeth which interlock when screwing-in is complete and snap together to prevent loosening of the rings. The tooth flanks that engage one another on loosening are nevertheless sufficiently angled to enable forced unscrewing using a spanner. A skirt (14) protects the mechanism and acts as an abutment in the fully screwed-in position. Said seal enables locking and unlocking, requires no direct manual operation and is particularly suitable for endoscope insertion openings in aircraft engines.
