Clamping hardware

Abstract

This item is a clamping hardware for gripping pipes, piles, etc. This item is made of metal and, as shown in the "Reference Oblique View (1) Showing the State Before the Bolt is Screwed in," is composed of a clamp tube body, a bolt, a clamping block, a clamping nut, and a locking nut. The clamping block and clamping nut are formed in a cylindrical shape. The clamping block has an axial hole through which the screw shaft of the bolt is inserted. The clamping nut has a threaded hole through which the screw shaft of the bolt is screwed. The clamp tube body is made from a single plate shaped like a cylinder, with identically shaped positioning holes formed at each end of the plate. The clamping block and clamping nut are inserted into the positioning holes and fixed to the clamp tube body. This item is attached to, for example, a pipe or pile, etc., and grips the pipe or pile, etc. As shown in "Reference Oblique View (2) Showing the State Before the Bolt is Threaded" and "Perspective View (1)," the threaded shank of the bolt is inserted into the shank hole of the clamping block, then threaded into the threaded hole of the clamping nut and protruding from the clamping nut. This product involves inserting a pipe, a pile, or the like into the clamping tube body, and rotating the bolt's threaded shank in one direction relative to the clamping nut, causing the end face of the bolt's head to abut against the end face of the clamping block. By rotating the bolt in one direction, the clamping hole (tube diameter) in the clamping tube body contracts, clamping and gripping the pipe, pile, or the like. A locking nut is threaded onto the threaded shank protruding from the clamping nut. The locking nut rotates in the other direction relative to the screw shank and abuts against the end face of the clamping nut. Tightening the locking nut prevents the screw shank from rotating in the other direction and loosening.
