Abstract

The invention relates to the field of pipe fittings, in particular to a self-adaptive connecting device for multi-diameter tubular components. Comprising a pipe fixing piece, a connecting piece, a driving piece and a plugging piece, the pipe fixing piece comprises an outer pipe fixing strip and an inner pipe fixing strip which are both threaded elastic strips, the outer pipe fixing strip and the inner pipe fixing strip are installed between a large-diameter pipe and a small-diameter pipe, and the outer pipe fixing strip and the inner pipe fixing strip are installed between the large-diameter pipe and the small-diameter pipe. The driving part drives the outer pipe fitting fixing strip and the inner pipe fitting fixing strip to be far away from each other along the trapezoidal inclined surface, and the diameter of the outer pipe fitting fixing strip is increased, so that the outer side wall of the outer pipe fitting fixing strip is expanded outwards to abut against the inner side wall of the large-diameter pipe; and the diameter of the inner pipe fitting fixing strip is reduced, so that the inner side wall of the inner pipe fitting fixing strip is inwards shrunk to be propped against and pressed against the outer side wall of the small-diameter pipe, thereby adapting to the connection between tubular members with different pipe diameters.

Description

technical field [0001] The invention relates to the field of pipe fittings, in particular to an adaptive connection device for multi-diameter tubular members. Background technique [0002] When the pipeline is produced, considering the technological requirements of processing and the convenience of transportation, there is generally a length limit, and the length of the pipeline laying is not limited. Therefore, the pipeline needs to be connected when it is laid and used. The pipe joint generally adopts a cylindrical pipe section, and inserts the small-diameter inner pipe part into the large-diameter outer pipe part in a tight fit, and uses a fastening plug between the two pipe fittings of different diameters. tight connection. The existing commonly used connectors are mostly the connection between pipe fittings with a specific size and diameter, and in actual situations, there are often some deviations in the production of the same type of pipe fittings by different manufa...
