[0002] Braided hoses are common accessories for connecting waterways. They are widely used and are increasingly being used in challenging environments. Corrosion resistance and UV resistance have become standard requirements.

[0003] At present, the general design of the hose for connection is still retained in the stage of exposed steel sleeve, which affects the overall appearance of the hose. In addition, although the steel sleeve, which is the key stamping connection of the hose, is made of stainless steel rust-proof material, it is exposed for a long time and is still easily affected by external UV, water erosion, cleaning waste liquid, etc., increasing the risk of corrosion and shortening the service life.

[0004] Therefore, based on some of the above prior art situations, the present application has been further designed and improved. Utility Model Content

[0005] In view of the above deficiencies in the prior art, the utility model provides an improved flexible hose with a nut structure, which is used to solve the problem of the steel sleeve being exposed to the outside for a long time in the prior art.

[0006] In order to solve the above technical problems, the utility model solves them through the following technical solutions.

[0007] An improved flexible hose with a nut structure comprises a braided tube, steel sleeves mounted at both ends of the braided tube, and a nut sleeved on the outside of the steel sleeve, wherein the nut comprises a twisting portion and an extended protective portion, and the extended protective portion covers the steel sleeve. The extended protective portion can hide and shield the steel sleeve, reduce the impact of the outside on the steel sleeve, and improve the consistency of the appearance.

[0008] As a preferred implementation scheme of the improved flexible hose with a nut structure described in the utility model, specifically, the twisting part and the extended protection part are designed as one piece, which is beneficial to strengthen the shielding protection of the steel sleeve and the copper core, and has a sense of integration, which is beneficial to improving the external visual effect of the hose.

[0009] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, the surface of the nut is provided with a coating to enhance the terminal customers' willingness to use and their demand for high-end decoration matching.

[0010] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, the twisting portion is a hexagonal nut structure, and the corners of the hexagonal nut structure adopt rounded transition, which is visually simpler and more beautiful.

[0011] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, the braided tube includes a flexible inner tube, the outside of which is covered with braided wires, which can have sufficient compressive strength while ensuring the curvature of the tube body, thereby ensuring the softness of the braided tube and improving the protection of the flexible hose.

[0012] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, the flexible inner tube is made of impact-resistant and pressure-resistant, non-toxic materials, has high external pressure resistance, strong impact resistance, and good flexibility.

[0013] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, the braided wire is made of corrosion-resistant material, which effectively prevents corrosion and reduces the overall weight, which is conducive to reducing production and transportation costs.

[0014] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, a copper core is assembled on the steel sleeve, and the copper core is extruded and sealed with the braided tube by means of stamping and key dimensions to ensure the firmness of the connection between the copper core and the braided tube.

[0015] As a preferred embodiment of the improved flexible hose with a nut structure described in the utility model, specifically, a sealing gasket is mounted on the end surface of the copper core to ensure the connection sealing of the flexible hose.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the nut structure is optimized, and an extended integrated covering design is adopted; after the braided hose is connected to the angle valve, tee and other water accessories, the steel sleeve can be hidden and shielded, thereby reducing the external influence on the steel sleeve and the copper core, and improving the visual effect and practicality.
