[0002] Metal hoses are important components in the connection pipelines of modern industrial equipment. Metal hoses are used as wire and cable protection tubes for wires, cables, and automation instrument signals, as well as civilian shower hoses. Small-diameter metal hoses are mainly used for sensor line protection of precision optical rulers and industrial sensor line protection. However, when using metal hoses, when the metal hoses are bent, the bearing force of the bending area of ​​the metal hoses will change, causing the pipe wall of the pipe to be unevenly stressed and ruptured during transportation. Therefore, high-strength and flexible metal hoses are required.

[0003] The application number retrieved is: CN201710747762.1, a metal hose. The metal hoses are extremely fast to load and unload, easy to operate, and effectively improve work efficiency.

[0004] However, the existing metal hoses still have certain defects in actual use: when the metal hose is in use, when the metal hose needs to be bent, the stress in the bent area of ​​the pipe will change, which will cause the impact change on the bent area of ​​the pipe to increase when the transported liquid impacts the bent area. For this reason, we propose a metal hose with high strength and good flexibility. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a metal hose with high strength and good flexibility, aiming to improve the problem that when the metal hose needs to be bent during use, the stress in the bending area of ​​the pipe will change, thereby causing the impact change of the bending area of ​​the pipe to increase when the transported liquid impacts the bending area.

[0006] The utility model realizes a high-strength and flexible metal hose through the following technical scheme, including a pipe body, a reinforcement layer and a flexible layer, both ends of the pipe body are equipped with connecting rings, and the pipe body includes a wear-resistant layer, a flexible layer, a reinforcement layer, a buffer layer and a corrosion-resistant layer, and the flexible layer is arranged on both sides of the inner wall of the wear-resistant layer, and the reinforcement layer is arranged on the side of the flexible layer away from the wear-resistant layer, and the buffer layer is arranged on the side of the reinforcement layer away from the flexible layer, and the corrosion-resistant layer is arranged on the side of the buffer layer away from the reinforcement layer.

[0007] Furthermore, the flexible layer includes a nylon fiber layer and a metal copper sheet layer, and the outer surface of the nylon fiber layer is wound with the metal copper sheet layer in a clockwise direction.

[0009] Furthermore, the wear-resistant layer includes an alloy steel layer and a tungsten-metal layer, and the alloy steel layer and the tungsten-metal layer are interlaced with each other, and the wear-resistant layer has a mesh structure as a whole.

[0011] Furthermore, the corrosion-resistant layer includes a stainless steel layer, a passivated carbon steel sheet layer and a bonding layer, and the passivated carbon steel sheet layer is arranged on the right side of the stainless steel layer, and the bonding layer is arranged on the side of the passivated carbon steel sheet layer away from the stainless steel layer.
