Quick mounting joint for corrugated pipe and corrugated pipe applying quick mounting joint

Abstract

The invention discloses a quick mounting joint for a corrugated pipe and the corrugated pipe applying the quick mounting joint, and belongs to the technical field of corrugated pipe joints. The quick mounting joint comprises a base internal thread joint and an external thread joint which are matched with each other, a hollow check ring is installed in the external thread joint and comprises an embedded section and an expansion section, a clamping ring is installed on the periphery of the expansion section and comprises a plurality of clamping ring bodies of arc structures and elastic rings, and connecting grooves are formed in the peripheries of the clamping ring bodies in the circumferential direction; the elastic rings are embedded into the connecting grooves, and the multiple clamping ring bodies are sequentially connected in series through the elastic rings to form a ring body structure; and a split ring of a ring body structure is installed in the base internal thread, the outer side end of the split ring makes contact with the clamping ring, and the end of the expansion section makes contact with the outer side end of the split ring. The invention provides the quick mounting joint for the corrugated pipe and the corrugated pipe applying the quick mounting joint, and the quick mounting joint is simple in structure and convenient to mount, and can realize quick mounting on the premise of ensuring good air tightness of the corrugated pipe.

Description

Technical field [0001] The present invention relates to the field of bellows joints, and more particularly to a bellows rapid mounting joint and a bellows to which the joint is applied. Background technique [0002] Metal bellows as sensitive components, shock absorbers, compensating components, sealing elements, valve components, and pipeline connectors, are widely used in automatic control and measuring instruments, vacuum technology, mechanical industries, electric power industry, transportation and atomic energy industry. . [0003] The connection method of the metal bellows generally uses flanged connection, welding, wire buckle connection, quick joint connection, etc., small-diameter metal bellows generally adopt a wire buckle and fast joint, and a larger diameter is generally a flange connection and welding. At present, the user's ability to install the stainless steel corrugated hose is installed, and the performance requirements in use are increasing, not only can be abl...

AI Technical Summary

Problems solved by technology

At present, users have higher and higher requirements for the performance of stainless steel corrugated hoses during installation and use. Not only must they be able to achieve quick installation, reliable sealing, but also have the function of preventing disassembly. Therefore, it is urgent to design a bellows quick installation joint with simple structure, reliable sealing and quick installation.
