UPPER AND LOWER COUPLINGS CAPABLE OF BEING EASILY COMBINED AND JOINED WITHOUT ASSEMBLING A BOLT AND A NUT

摘要

PURPOSE: Upper and lower couplings capable of being easily combined and joined are provided to improve assembling work efficiency by simultaneously forming both periphery slits on upper and lower couplings.;CONSTITUTION: Upper and lower couplings(10,10a) have linear slits(12) and peripheral slits(13). The linear slits are formed in the longitudinal direction on the middle of the front end outside periphery of the upper and lower couplings and formed at the end of the linear slits. An inward projection(31) of a bond ring(30) is inserted into the linear slits of the upper coupling in the longitudinal direction, bond ring is rotated to one peripheral slits, the inward projection of the bond ring is inserted into the end grooves(14) of one peripheral slits, and the ends of the upper and lower couplings are coupled by the bond ring.;COPYRIGHT KIPO 2010
