AI Technical Summary
Technical Problem
Existing fire hoses are prone to wear and tear in fire environments due to friction with rough surfaces, resulting in cracks, poor wear resistance, and short service life.
Method used
The hose body is equipped with a wear-resistant buffer layer and a sliding friction ring. The sliding friction ring consists of a fixed ring body and freely sliding balls, which replace sliding friction with rolling friction. The buffer layer is composed of a TPU yarn braided layer and a silicone buffer layer, which provides cushioning and protection.
Benefits of technology
It significantly reduces friction, extends the service life of water hoses, improves tensile strength, prevents wear on water pipe layers, and enhances service durability.

Abstract
The utility model relates to the technical field of fire fighting, in particular to a wear-resistant fire-fighting lance water hose which comprises a water hose body, the water hose body comprises a water pipe layer, a wear-resistant buffer layer is arranged on the outer wall of the water pipe layer, a plurality of sliding friction rings are embedded in the outer wall of the wear-resistant buffer layer, and the water pipe layer is isolated from the outside contact surface through the wear-resistant buffer layer. Buffering is provided when the water pipe layer receives drawing force, and friction sliding is replaced by rolling of the sliding friction ring when the sliding friction ring makes contact with the external contact face.
