Description

Technical Field

[0001] This utility model relates to the field of metal hose technology, specifically a wear-resistant metal hose. Background Technology

[0002] Metal hoses, as a key component, play a vital role in modern industry and daily life. They are primarily used to transport liquids, gases, and other fluid media, and can adapt to various complex operating environments, including high temperatures, high pressures, and applications requiring flexibility and bend resistance. However, with the continuous expansion of application scenarios and the increasing demands of technology, traditional metal hoses are gradually showing their inadequacy in terms of wear resistance.

[0003] In practical applications, metal hoses are typically exposed to various external environments, including abrasive particles, corrosive chemicals, and extreme temperatures, all of which pose significant challenges to the outer layer of the hose. For example, in high-abrasion working environments such as mines, construction sites, or chemical production processes, metal hoses are easily worn down by friction from external particles, leading to a substantial reduction in their service life. Furthermore, for applications requiring good thermal insulation, such as high-temperature steam transfer systems, ordinary metal hoses often fall short because they lack effective insulation measures, potentially resulting in heat loss or adverse effects on the external environment.

[0004] To address the aforementioned problems, existing technologies have proposed several improvements, such as using more wear-resistant materials to manufacture the outer layer of the metal hose, or adding an insulation layer inside the metal hose to improve overall insulation performance. However, these solutions still have certain limitations: on the one hand, replacing the entire metal hose is costly; on the other hand, while some designs improve wear resistance or insulation, they sacrifice other performance aspects, such as flexibility or ease of installation. Therefore, this utility model proposes a wear-resistant metal hose. Utility Model Content

[0005] Technical problems to be solved

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a wear-resistant metal hose. By incorporating threaded fixing sleeves and removable anti-wear sleeves at both ends of the metal hose, the worn anti-wear sleeves can be replaced individually, thereby reducing usage costs and extending the overall lifespan of the metal hose. Simultaneously, optimized internal structure further enhances the product's heat insulation performance, making it more suitable for various complex working conditions.

[0007] Technical solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant metal hose, comprising a metal hose with end connectors at both ends of the outer surface of the metal hose, a connecting thread on one side of the end connector, and a connecting portion on one side of the end connector, the end connector being threadedly connected to a fixing sleeve via the connecting thread, a detachable anti-wear sleeve being clamped between the fixing sleeve and the connecting portion, the two ends of the anti-wear sleeve being sleeved onto the two ends of the metal hose, and by providing threaded fixing sleeves on the end connectors at both ends of the metal hose, the anti-wear sleeve can be fixed in use via the threaded fixing sleeves, and the anti-wear sleeve can be disassembled by loosening the fixing sleeves, thereby making it easy to disassemble and replace the anti-wear sleeve after it wears, and thus allowing the outer anti-wear sleeve of the device to be replaced separately after it wears, saving costs;

[0009] The metal hose has an inner tube inside, and an insulating cotton sleeve is placed in the gap between the metal hose and the inner tube. A metal braided mesh is fitted over the insulating cotton sleeve. The insulating cotton sleeve improves the heat insulation effect of the device.

[0010] Preferably, the connecting part is provided with anti-slip protrusions, and one side of the anti-slip protrusions is provided with an inclined slope.

[0011] Preferably, the fixing sleeve is provided with a fixing step, and the fixing step is adapted to the anti-slip protrusion.

[0012] Preferably, the side of the fixed step that is in contact with the anti-slip protrusion is provided with a number of evenly distributed anti-slip protrusions.

[0013] Preferably, the outer surface of the inner tube is coated with a nano-scale ceramic layer or a polyurethane-based wear-resistant coating.

[0014] Preferably, the abrasion sleeve is made of nylon braided material.

[0015] Preferably, the wear-resistant sleeve has an internal heat insulation layer, which includes polyacrylonitrile fiber and polyester fiber layers. The heat insulation layer fills the gap between the wear-resistant sleeve and the metal hose. The heat insulation layer further improves the heat insulation effect of the device and enhances its practicality.

[0016] Beneficial effects:

[0017] Compared with existing technologies, this wear-resistant metal hose has the following advantages:

[0018] This invention features threaded fixing sleeves on the end connectors at both ends of the metal hose. During use, the threaded fixing sleeves secure the anti-wear sleeve, and loosening the fixing sleeves allows for disassembly of the anti-wear sleeve. This facilitates easy removal and replacement of the anti-wear sleeve after it wears out, enabling separate replacement of the outer anti-wear sleeve, thus saving costs. Furthermore, the addition of a heat-insulating cotton sleeve improves the heat insulation effect of the device, further enhancing its practicality. Attached Figure Description

[0027] Please see Figures 1-4As shown, this utility model provides a technical solution: a wear-resistant metal hose, including a metal hose 1, with end connectors 2 at both ends of the metal hose 1. One side of the end connector 2 is provided with a connecting thread 201, and another side of the end connector 2 is provided with a connecting portion 202. A fixing sleeve 3 is threadedly connected to the end connector 2 via the connecting thread 201. A detachable anti-wear sleeve 4 is clamped between the fixing sleeve 3 and the connecting portion 202. The anti-wear sleeve 4 is made of nylon braided material, and its two ends are fitted onto the two ends of the metal hose 1. By providing threaded fixing sleeves 3 on the end connectors 2 at both ends of the metal hose 1, the anti-wear sleeve 4 can be fixed in use via the threaded fixing sleeves 3. Loosening the fixing sleeves 3 also allows for the disassembly of the anti-wear sleeve 4, making it easy to remove and replace the anti-wear sleeve 4 after it wears out. This allows the outer anti-wear sleeve 4 of the device to be replaced individually after wear, saving costs.

[0030] Please refer to the following carefully. Figure 2 and Figure 3 The wear-resistant sleeve 4 has an internal heat insulation layer 9, which includes a polyacrylonitrile fiber 901 and a polyester fiber layer 902. The heat insulation layer 9 fills the gap between the wear-resistant sleeve 4 and the metal hose 1. The heat insulation layer 9 further improves the heat insulation effect of the device.

[0031] Working principle: Threaded fixing sleeves 3 are provided on the end connectors 2 at both ends of the metal hose 1. During use, the anti-wear sleeve 4 can be fixed by the threaded fixing sleeves 3, and the anti-wear sleeve 4 can be disassembled by loosening the fixing sleeves 3. This allows the anti-wear sleeve 4 to be easily disassembled and replaced after wear, thus enabling the outer anti-wear sleeve 4 of the device to be replaced separately after wear, saving costs. In addition, the setting of the heat insulation cotton sleeve 6 improves the heat insulation effect of the device, and the setting of the heat insulation layer 9 further improves the heat insulation effect of the device.
