Description

Technical Field

[0001] The utility model relates to the technical field of hoses, in particular to a stainless steel braided hose which is easy to assemble. Background Art

[0002] Braided hose is a widely used product in water heating and gas equipment. Braided hose is highly safe, easy to use and simple in structure. At present, the traditional braided hose includes a tube body, wherein the tube body is composed of a braided layer and an inner tube, and the two ends of the tube body are respectively fixed with a connecting core through a steel sleeve, and a connecting nut is provided on the connecting core, and a ferrule is respectively provided at the two ends of the tube body; At present, the traditional braided hose has the following main defects:

[0003] 1. Since the inner wall of the inner tube of the existing braided hose is a smooth surface, when the diameter of the inner tube is too large, the connecting core cannot be fixed with the inner tube, and the connecting core needs to be fixed by a steel sleeve after being inserted into the inner tube. Therefore, during the installation process, the connecting core may fall off, which brings manual workload, wastes working time, and has low production efficiency. If the diameter of the inner tube is too small, the connecting core cannot be installed in the inner tube, so that no matter whether the diameter of the inner tube is too large or too small, it will cause trouble to production.

[0004] 2. The existing inner tube is covered with a braided layer. When the braided layer and the two ends of the inner tube are not aligned, they need to be cut. Since the outer wall of the inner tube is a smooth surface and the braided layer has a certain elasticity, after cutting the braided layer and the two ends of the inner tube, it is easy to cause the braided layer to slip or shrink, so that the braided layer cannot wrap the inner tube, resulting in the connection core and the steel sleeve cannot be installed normally, resulting in the need to adjust the braided layer every time it is assembled, which is not only labor-intensive and time-consuming, but also cumbersome to operate, increasing the workload and low production efficiency.
