AI Technical Summary
Technical Problem
The inflation hose for dual-wheel tires is prone to dents, deformation, and breakage due to bending at a large angle within the narrow rim space and suffers wear and damage from friction during high-frequency inflation, posing safety risks.
Method used
An inflation tube device with a flexible tube body, first and second joints, and a cylindrical spring, allowing threaded connections to the air inflator and air nozzle without bending, and the spring covering the tube body to prevent excessive bending and friction.
Benefits of technology
Provides a stable, wear-resistant connection that prevents hose damage and improves durability by eliminating the need for manual fixing and reducing friction, ensuring safe and convenient inflation operations.

Abstract
To provide an inflation tube device that can be stably connected between an air inflator and a dual wheel tire and has wear resistance. [Solution] The inflation tube device is adapted to be connected between an air inflator and a dual-wheel tire, the dual-wheel tire including an outer and inner ring, the outer ring including an air nozzle facing the inner ring. The inflation tube device includes a flexible tube body (110), a first joint (120), a second joint (130), and a cylindrical spring (140). The flexible tube body includes opposing first and second tube body ends (112, 114). The first joint is connected to the first tube body end and adapted to be threadedly connected to the air inflator. The second joint is connected to the second tube body end, and the second joint extends from the space between the outer and inner rings and is adapted to be threadedly connected to the air nozzle. The cylindrical spring is disposed over the flexible tube body and is fixed to the first and second tube body ends, surrounding a portion of the first and second joints.
