Description

Technical Field

[0001] This utility model relates to the field of water hose technology, and in particular to a water hose with an interface. Background Technology

[0002] Water hoses are flexible tubes used to transport high-pressure water or foam. They are generally made by bending and overlapping planar composite wall materials in the circumferential direction to form a tube. The overlapping tubular composite wall material is called the "pipe wall". Water hoses are usually connected by joints to extend their length. In the current technology, water hose joints are usually fixed to the water hose by welding. When the joint is welded to the water hose, problems such as incomplete welding, burn-through, and uneven welding may occur, leading to leakage or breakage between the joint and the water hose, affecting the normal use of the water hose.

The outer diameter of the first connecting pipe 61 is smaller than the outer diameter of the second connecting pipe 62.
