Diameter-adjustable end joint for hose

Abstract

The invention discloses a diameter-adjustable end connector for a hose. The diameter-adjustable end connector comprises a metal hose and screws; fixing connectors are arranged at the two ends of the metal hose and connected to a flexible connector; the flexible connector is in a trapezoidal pleated shape, a circle of connector groove is formed in the outer wall of each fixing connector, and a fixing disc is arranged in each connector groove; a plurality of screw holes are formed in each fixing disc, and the screws penetrate through the screw holes; and fixing heads are arranged at the tails of the screws, hoop body grooves are formed in the tops of the fixing heads, locking hoops are arranged on the outer side of the flexible connector, and the locking hoops are connected to the hoop body grooves in a clamped mode. According to the diameter-adjustable end connector, the flexible connector is arranged, and the flexible connector is in a trapezoidal pleated shape; the flexible connector is matched with the locking hoops, and the diameter of the locking hoops can be adjusted at any time, so that the diameter of the flexible connector is controlled, and the application range of the metal hose is widened.

Description

technical field [0001] The invention relates to an end joint for a hose with adjustable diameter. Background technique [0002] At the production site of the enterprise, there are often some equipment that use gas or liquid working medium. The hose joint is an important part that connects the hydraulic equipment and the rubber hose. The connection and use of pipes is a relatively common phenomenon, especially in thermal processing units that use oxygen, gas, compressed air, nitrogen, hydrogen, argon, carbon dioxide gas, etc. as working media. The connection methods of hoses are generally connected by iron wire binding or pipe clamps (including extruded pipe clamps and screw tensioned pipe clamps). The common feature of these three connection methods is that the bundled or clamped hoses have Inner shrinking extrusion deformation is realized by the anti-slip friction resistance between the inner surface of the hose or the inner surface of the inner tube and the outer surface ...

AI Technical Summary

Problems solved by technology

The connection methods of hoses are generally connected by iron wire binding or pipe clamps (including extruded pipe clamps and screw-tensioned pipe clamps). The common feature of these three connection methods is that the bundled or clamped hoses produce Inner shrinking extrusion deformation is realized by the anti-slip friction resistance between the inner surface of the hose or the inner surface of the inner tube and the outer surface of the connecting tube core (inverted tapered pipe joint or smooth straight pipe joint with large and small head diameters) For sealing and connection, the connection force is only generated on the inner surface of the pipe. Without the use of special tooling and tools, the connection strength and sealing performance are not easy to guarantee, easy to leak, or even fall off, and the loading and unloading operations are cumbersome and laborious.
