Buckling assembly nut for pipeline connection

Abstract

The invention relates to the technical field of pipeline connecting pieces, in particular to a buckling assembly nut for pipeline connection. The buckling assembly nut for pipeline connection is provided with a body. The body is provided with an inner hole of which the diameter is more than that of an outer shoulder at a pipe fitting connection end. The radial thickness of the connection rear end of the body is less than that of the connection front end of the body. The buckling assembly nut is installed after the processes of bending or welding and the like of a pipeline are completed, so that the intermediate processing of the pipeline is facilitated, the processing difficulty is reduced, the processing efficiency of the product is improved, the nut is quick, convenient and reliable to install, a pipe fitting can be prevented from being scrapped due to false installation or neglected loading of the nut, and the whole production efficiency of the pipeline can be improved.

Description

technical field [0001] The invention relates to the technical field of pipeline connectors, in particular to a nut for a crimping device for pipeline connection, which is mainly used for crimping assembly of automobile air-conditioning pipelines. Background technique [0002] Nut bolt connection is a very common connection method used in pipelines. Generally, the connection end of the pipe fittings will be made into a form with an outer shoulder, and the inside of the nut can be made into an inner shoulder to facilitate the firmness of the nut. This structure requires The nut is pre-set on the pipeline from the other end before the pipeline bending, welding and other processing. Since the inner shoulder size of the nut is smaller than the outer shoulder size of the pipe fitting connection end, the nut cannot be installed on the pipeline after the pipe is bent. The processing of the final pipeline will be very inconvenient, and some special-shaped pipelines cannot even be pro...
