Description

Technical Field

[0001] The utility model relates to a metal-clad hose, in particular to a metal-clad hose for connecting gas appliances which is convenient to assemble and disassemble, and belongs to the technical field of gas appliance connecting pipes. Background Art

[0002] The two ends of the existing metal-clad gas hose are connected to the gas appliance and gas meter respectively using threaded sleeves. The common threaded sleeve has a fixed end connected to the hose and a threaded end connected to the gas appliance. During installation, a torque wrench is used to rotate the threaded end to fix it to the gas appliance. However, since this type of hose uses a threaded connection, its threaded end often rotates due to external force and eventually becomes loose. In order to overcome this situation, the existing technology generally adopts an anti-loosening design for the thread, using reverse threads or anti-loosening wires for fixing. However, when these designs are adopted, the disassembly process becomes more complicated and difficult to complete in a cramped space. Therefore, further improvement is needed.
