The invention relates to a burner connecting structure. The burner connecting structure comprises a cylindrical connecting rod; the end of the cylindrical connecting rod is provided with a columnar connector in an insertion way; one end of the connector is an inserting end; the other end of the connector is a metal connecting end; the middle part of the connector is provided with a protruding rim;the outer wall side of the end of the cylindrical connecting rod is provided with a locking cap in a sleeving manner; the top of the locking cap is provided with a connector passing hole; the sidewall of the outer wall of the end of the cylindrical connecting rod is circumferentially provided with an annular catching groove; the inner sidewall of the locking cap is also circumferentially providedwith an annular catching groove; and the cylindrical connecting rod and the locking cap are connected in a matching way by being buckled with each other by utilizing the annular catching grooves. Theburner connecting structure provided by the invention is applicable to connection of a composite tubular product and metal, is of a connecting structure free of combination of screw threads inside and outside, is mainly applicable to composite tubular products and aims to furthest increase the destructive tensile force.
Description
technical field [0001] The invention belongs to the field of pipe fitting structure connection, and relates to a pipe fitting connection structure, in particular to a burner connection structure used for pipe fitting connection. Background technique [0002] When rods made of composite pipes are connected between rods or between rods and other metal rods, most of them are connected by a single ordinary thread. When the rods are stressed, the stress on the threaded joints is the largest. , A single threaded connection often fails to reach the maximum destructive force of the rod, and the strength of the threaded connection is equivalent to one-third of the strength of the pipe itself, and it will be destroyed in advance. As a result, the tensile strength of the composite pipe member cannot be fully utilized. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a burner connecti...
