| 摘要 |
<p>The invention concerns a system for assembling two tubular parts (1, 2), the assembly being capable of being locked and unlocked, without a device with large space requirement. It consists mainly of a serrated ring (10, 20) on each of the two tubular parts (1, 2) having each a series of teeth (11, 12) provided with radial flanges (12) straight for the first of the serrated rings and inclined (22) for the second of the serrated rings. The assembly is completed with a locking ring (30) provided with wedges (31) designed to be inserted between the flanges (12, 22) of the two rings, once the latter are interlocked. The rotation of the locking ring (30) enables, through its inclined clamping surfaces (33) of the wedges (31) to secure the two tubular parts (1, 2). A positioning ring (40) can be used to centre the parts and pick up the shearing force resulting from a transverse mechanical modification. The invention is applicable to detachable assembly of large-size tubular parts.</p> |
