Description

Technical Field

[0001] The present application relates to the technical field of rubber hoses, and in particular to a pulse-resistant high-pressure steel wire wound rubber hose. Background Art

[0002] The patent with the published authorization announcement number CN219673564U discloses a pulse-resistant high-pressure steel wire wound hose assembly, including a tube body, the tube body including an inner tube, a steel wire winding layer and an outer tube, the steel wire winding layer is arranged between the inner tube and the outer tube, a pulse-resistant layer is arranged on the outside of the steel wire winding layer, and the pulse-resistant layer is located between the inner tube and the outer tube; both ends of the tube body are fixedly provided with mounting joints, the tube wall of the tube body is provided with an anti-bending spring, and the two ends of the anti-bending spring are respectively fixedly connected to the two mounting joints, which not only has strong pulse resistance, but also has high bending resistance, so that the total layer of the hose is not easily damaged by bending, thereby extending the service life.

[0003] The pulse-resistant high-pressure steel wire wound hose in the above patent is provided with an anti-bending spring on the outside of the tube body so that the tube body can rebound by itself after being bent and is not easily bent and damaged.
