Screwed coaxial connector for latticework of round tubes - has tube end bead with centring face supporting outer cone and round-wire circlip for inner one

摘要

A thickened bead (3) at the tube (2) end has a radial centring face (3a) supporting the outer clamping cone (5), and a round-wire circlip (4) fitting in a mating groove supporting the inner cone (8). Between the outer cone and the locking sleeve (17) is an adjusting sleeve (6). This has a flange bearing against the outer cone and profiled for turning by a spanner. It turns freely in the outer cone, in which it is centred, and the threaded locking sleeve is adjustable in it. Components (14) transmit a relatively small torque between the bolt (10) and the sleeve. ADVANTAGE - Greatly reduces friction torque when tightening the bolt, which can be replaced.
