Tube connection device

Abstract

The invention discloses a tube connection device which comprises a ring body, caps and outer bushes. Each outer bush comprises a first bush body and a convex bag portion. When the caps are screwed onto the ring body, the outer bushes can be driven to move towards the interior of the ring body; and when the outer bushes move inwards, the inner side wall of the ring body generates radial inward extrusion force to the convex bag portions. The tube connection device has the advantages that when tube connection is needed, to-be-connected tubes sequentially penetrate the caps and the outer bushes tobe inserted into the ring body, then the caps are unceasingly screwed, and in the process of screwing the caps, the caps unceasingly get close to the ring body; and in the process, step portions on the inner sides of the caps can unceasingly extrude the outer bushes, the convex bag portions generate extrusion to the side walls of the to-be-connected tubes, the to-be-connected tubes generate deformation, and therefore the connection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline connection equipment, in particular to a pipeline connection device. Background technique [0002] In the pipeline laying process, especially for air-conditioning pipelines, due to the limited length of the pipeline, the pipeline generally needs to be connected. Among them, there are many ways to connect the pipeline. At present, the most commonly used method is welding, and the connection method can be directly operated. , simple structure, beautiful appearance, etc., but welding connections also have some limitations, such as environmental requirements, raw material requirements, welding techniques, etc. [0003] At the same time, open flame welding also has a very large potential safety hazard. The fires in many construction sites reported by the media are mostly caused by sparks generated by welding operations. [0004] Therefore, there is currently a need for a pipeline connection device th...
