ABSTRACT:
A snap ring includes a body made of iron or steel, which has a fixing ring on its head in a semicircular or triangular shape and a rotatably and laterally joined rope guiding pulley on its inner lower portion. The snap ring further includes a link bar hinged to open or close the body, and a locking device for locking or unlocking the link bar. The closing procedure is performed by the link bar's hook and the locking device's locking hole provided with a resilient force by a coil spring. In unlocking, the link bar is released by raising the locker with a finger put into the locking device's unfastening hole. This prevents the rope from escaping from the snap ring, contrary to the prior art, as well as providing simplified and easy-to-operate structure. Accordingly, the snap ring of the present invention prevents industrial damages.
