Abstract
The invention relates to an open chain tightener which comprises an elephant foot, a hook head, a threaded rod and a body. The bottom end of the elephant foot is fixed in a socket, the top end of the elephant foot is installed at one end of the body, the hook head is arranged in a sliding groove in the middle of the body, the threaded rod penetrates through a threaded hole in the bottom of the hook head, the threaded rod head is inserted into the body, and the transverse movement of the threaded rod head is limited through a nut installed on the threaded rod head. A split pin assembly is installed on the threaded rod beside the nut and abuts against the end of the nut, a rotating head is arranged on the tail portion of the threaded rod, a locating slot is formed in the threaded rod beside the rotating head, and the rotating head and the locating slot are both positioned on the outer side of the body. A plurality of threaded holes are formed in the end face of the tail end of the body, the tail portion of the body is connected with a chain, and a screw is arranged at the tail end of the chain. The problems of a complex mechanism providing tightening through hydraulic pressure and hydraulic oil leakage are solved, simple structural design is adopted, and the open chain tightener has good practical economic value.
