[0002] Oil hose is a tubular rubber product specially used for transporting oil. It is usually composed of inner and outer rubber layers and a skeleton layer. The design of this hose takes into account the special properties of oil, such as viscosity, corrosiveness and fluidity, to ensure that it can effectively and safely transport oil during use.

[0003] The existing oil hose has poor extrusion resistance. When the oil hose is subjected to external pressure, it is easy to deform or rupture. When this happens, it will cause oil leakage, which not only wastes resources, but also may pollute the environment, especially when dealing with toxic or harmful oils, such pollution may be more serious; and the oil hose connection operation is complicated, and the firmness of the connection needs to be improved. Mistakes often occur during the connection process, resulting in oil leakage during transportation. Utility Model Content
