Rapid water heating connecting structure

Abstract

The invention discloses a rapid water heating connecting structure. The rapid water heating connecting structure comprises a connecting pipe and a fixing pipe, the left end of the connecting pipe is fixed to a connecting sleeve in a threaded butt joint mode, a first check ring and a second check ring are welded on the inner side of the connecting sleeve, the first check ring and the second check ring are connected with the edge side of the right end of the fixing pipe in a butt joint mode, a first groove and a second groove are formed in the edge side of the right end of the fixing pipe, a ferrule is connected to the outer side of the fixing pipe in a sleeving mode, and a connecting block is welded on the ferrule. According to the rapid water heating connecting structure, through the designs that the corresponding first check ring and second check ring cooperate with a sealing ring in the first groove and a sealing ring in the second groove, and meanwhile, a limiting ring cooperates with a gasket on the inner side, the double sealing effect can be effectively achieved, and corresponding leakage is prevented; through the design that a fixing ring cooperates with a sliding groove andthe connecting block, corresponding butt joint fixation can be quickly realized, so that the troublesome steps are omitted; and the rapid water heating connecting structure is flexible, convenient and fast, compact and reasonable in structural design, quite strong in practicability and suitable for popularization.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a fast plumbing connection structure. Background technique [0002] With the continuous improvement of living standards, people's requirements for plumbing products are getting higher and higher, and the connection devices of traditional plumbing products have been difficult to meet people's needs. Especially in the heating system in the north, due to the large temperature difference, the requirements for plumbing products are higher. The connection structure of plumbing in the prior art mainly has the following limitations: [0003] 1. The corresponding sealing is poor, and it is prone to leakage during use; [0004] 2. Most of them are not easy to be fast fixed and installed through threaded butt joints, and the structure is relatively responsible. At the same time, it is easy to rust and lock up after a period of use, and it is not easy to disassemble and repai...

AI Technical Summary

Problems solved by technology

[0003] 1. The corresponding sealing is poor, and it is prone to leakage during use;

[0004] 2. Most of them are not easy to be fixed and installed quickly through threaded butt joints. The structure is more responsible. At the same time, it is easy to rust and lock up after a period of use, and it is not easy to disassemble and repair.
