| 摘要 |
The invention concerns a chain link for conveyor belt, comprising, at the front and at the rear of a central web (4), slots (5, 6) provided with an opening (7) for passing through a hinge pin (8) designed to ensure the link between two successive chain links (1), said chain link (1) comprising at its ends (9, 10) axial locking means (11, 11A) for such a hinge pin (8). More particularly, said chain link comprises retractable locking means (11A) defined by the final front (5A) and/or rear slot traversed by an opening (12) with cross-section (13) smaller than that (14) of the hinge pin (8), with said opening (12) communicating with a slit (15) designed to enable expansion, by elastic deformation, of said opening (12) to reach a sufficient cross-section to allow the passage for introducing or removing said hinge pin (8). |
