[0002] Hydraulic equipment is widely used in engineering construction, industrial machinery, lifting and transportation and other fields. Hydraulic hoses are important tools for transmitting media for hydraulic equipment. At present, hydraulic equipment is generally connected by hydraulic hoses. For example, the hydraulic station oil supply pipeline system used in the ceramic high-pressure grouting production line, the hydraulic oil in the oil tank is driven by a hydraulic pump and transported to the oil block through a hydraulic hose. The hydraulic pressure inside the hydraulic hose is relatively large.

[0003] Hydraulic hoses generally use metal pressed joints at the ends, and hydraulic hoses are often used to connect two or more sections as needed. The butt-jointed hydraulic hoses are usually fixed by clamps or some simple strapping. Hydraulic hoses may become detached during use. Sometimes, due to aging or damage of the U-shaped clamp or illegal use of single clamps or wires, the pipeline may crack, causing the connection of the hose to fall off, resulting in oil leakage and affecting the use of hydraulic equipment.
