Description

Technical Field

[0001] The present invention relates to the technical field of hoses, and in particular to a telescopic hose and a manufacturing method thereof. Background Art

[0002] Existing telescopic tubes that can be powered generally utilize ordinary steel wire or copper-plated steel wire wrapped around a flexible flexible tube to achieve the tube's conductive function. However, these tubes contain both conductors and support members, and are coated with multiple wires. Because the coated wires cannot be stretched, a longer inner spiral folding layer is required to achieve a certain stretch ratio. This results in a thicker tube wall. For a given outer diameter, the inner bore of the tube will be relatively small, affecting the flow of gas and liquid, reducing its efficiency to a certain extent. Furthermore, the tube's heavy weight increases production costs and impacts user experience. Furthermore, while the tube can be retracted to a shorter length when not in use, it is still inconvenient to store. Therefore, the above issues urgently need to be addressed.
