A special high-strength pipeline fastener

Abstract

The invention belongs to the technical field of fasteners, specifically a special high-strength pipeline fastener; the fastening pipe includes a left fixed pipe and a right fixed pipe; The outer surface of the left solid pipe and the right solid pipe are fixedly connected with uniformly arranged fixed blocks; each of the fixed blocks is connected to the inner wall of the fixed block with evenly arranged bolts through threaded rotation, and the bolts are used for tightening Fix the left solid pipe and the right solid pipe; on the opposite side of the left solid pipe and the right solid pipe, there are uniformly arranged first arc-shaped grooves in the inner walls of the left solid pipe and the right solid pipe; each of the first arc-shaped Two opposite sides of the grooves are slidingly connected with arc-shaped layers in the cavity of the first arc-shaped groove; the invention is mainly used to solve the problem that the current pipeline fasteners can only be installed with pipes of uniform specifications, which greatly limits the size of the fasteners. At the same time, when the pipe is deformed, due to the large roundness error of the pipe, the fastener cannot seal the pipe.

Description

technical field [0001] The invention belongs to the technical field of fasteners, in particular to a special high-strength pipeline fastener. Background technique [0002] Fasteners are also called standard parts in the market, which is a general term for a type of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. It is characterized by a wide variety of specifications, different performances and uses, and a high degree of standardization, serialization, and generalization. Fasteners are the most widely used mechanical basic parts, and are in great demand. Fasteners are used in a wide range of industries, including energy, electronics, electrical appliances, machinery, chemicals, metallurgy, molds, hydraulics, and other industries. Among them, pipeline fastening Pipeline fasteners are often used in connection. At present, there are still some problems with pipeline fasteners, including the following aspects: [0003] The ...
