An improved structure lamp
pipe insert connector comprised of a locking connector component situated between upper and lower lamp pipes, the locking connector component comprised of a
threaded rod, a lock sleeve fastened onto the
threaded rod, and constraining rings respectively sleeved (not fastened) onto the two ends of the
threaded rod and, furthermore, situated at the two sides of the lock sleeve. The interior of the constraining ring is a sloped surface and a plurality of
detent slots are disposed along its inner circumferential extent and, after a spring is prepositioned on the sloped surface, it is then sleeved onto the threaded rod. Furthermore, there are revolving guide ring elements with beveled sides, each revolving guide
ring element having guide blocks aligned with the constraining ring
detent slot positions and capable of entry into the
detent slots, thereby providing for the synchronous rotation of the revolving guide ring elements and the constraining rings. When the lamp pipes drive the constraining rings into rotation, the revolving guide
ring element beveled sides are forced against the constraining ring sloped surfaces and become tightly ensconced within the inner circumference of the lamp pipes. As such,
assembly is simple and enables user self-
assembly and, furthermore, since each steel
pipe can be disassembled, shipping dimensions are minimized.
