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

[0002] High-pressure hoses are mainly used for conveying petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, water) with a certain pressure and temperature and liquid transmission pipelines in mine hydraulic supports, oil field development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in various industrial sectors.

[0003] The patent document with the published announcement number CN220770384U provides a high-pressure flame-retardant steel wire braided hose. This published patent document is achieved by sleeve-fitting two high-strength sealed flame-retardant sleeves on the outer surfaces of two steel wire braided hoses, and then clamping two clamping tubes on the outer surfaces of the high-strength sealed flame-retardant sleeves. The outer surface of each threaded shaft is respectively passed through the interior of each high-strength sealed flame-retardant sleeve, so that the limit block fixes the outer surface of the steel wire braided hose, and the two flanges are fixedly connected by bolts to complete the connection of the two steel wire braided hoses. However, in the above patent document, it is necessary to first fix the high-strength sealed flame-retardant sleeves on the outer surfaces of both ends of the steel wire braided hoses before subsequent fixing work can be carried out, and any two hoses cannot be connected at any time. The operation has certain limitations and is inconvenient to use. Utility Model Content

[0022] In the utility model, when any two braided hose bodies are connected to each other through pipelines, the two braided hose bodies are first inserted into the outer surfaces of the two ends of the connecting pipe, and then the fixing seat is tightened by rotating. During the tightening process, the inner wall of the fixing seat abuts and squeezes the outer wall of the elastic clip, so that the elastic clip can clamp and fix the braided hose body, thereby fixing any two braided hose bodies on the outer surfaces of the two ends of the connecting pipe. The operation has no limitations, is widely applicable, and is very flexible. After the installation is completed, the fixing sleeve is limited and fixed by inserting the limiting rod into the inside of the fixing sleeve, thereby achieving the effect of locking the fixing sleeve, avoiding loosening of the fixing sleeve, and ensuring that the braided hose bodies are firmly connected.
