[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-4 The present invention discloses a stainless steel braided hose connector, comprising a connector body 1, a threaded sleeve 2 movably fitted on the connector body 1, a connecting groove 3 for inserting the stainless steel braided hose 01 at the connecting end of the connector body 1, and a plurality of fan-shaped fixing pieces 5 formed by a plurality of partition grooves 4 equidistantly arranged in a ring array on the outer circumferential surface of the connecting groove 3, and a fastening sleeve 6 fitted on the assembly end of the connector body 1 and the stainless steel braided hose 01, the fastening sleeve 6 being fixed to the connector body 1 by a threaded hinge, the fastening sleeve 6 having a conical surface 7 for squeezing the fan-shaped fixing pieces 5 to deform and fix the stainless steel braided hose 01, and a first spiral protrusion ring 8 and a second spiral protrusion ring 9 respectively provided on two opposing circumferential sidewalls in the connecting groove 3, the spiral directions of the two being opposite.

[0026] A Y-shaped inflatable rubber ring 10 is provided between the connecting groove 3 and the inner diameter wall of the stainless steel braided hose 01. An annular groove 301 for assembling the Y-shaped inflatable rubber ring 10 is provided on the inner wall of the connecting groove 3. An arc-shaped groove 1001 is provided on the Y-shaped inflatable rubber ring 10 opposite to the inner diameter wall of the stainless steel braided hose 01. The fastening sleeve 6 is sealed to the assembly end of the connector body 1 by a sealing element, which is an annular inflatable rubber ring 11. A sealing element, a sealing ring 12, is provided inside the threaded sleeve 2 to seal the connector body 1 with the external connector. During operation, the end of the stainless steel braided hose 01 to be connected is aligned with the connecting groove 3 of the connector body 1 and aligned axially. The stainless steel braided hose 01 is inserted firmly to the bottom. The braided layer of the hose contacts the first spiral protrusion 8 and the second spiral protrusion 9 on the inner wall of the connecting groove 3. The spiral teeth of the outer wall of the stainless steel braided hose 01 and the first spiral protrusion 8 and the second spiral protrusion 9 form a three-dimensional meshing, preventing the stainless steel braided hose 01 from rotating circumferentially and increasing the contact area. Then, the fastening sleeve 6 is put on the assembly end of the connector body 1, aligned with the threads, and tightened. The conical surface 7 of the inner wall of the fastening sleeve 6 gradually approaches the fan-shaped fixing plate 5. The axial thrust of the conical surface 7 is decomposed into a radial force, causing the fan-shaped fixing plate 5 to elastically contract inward along the partition groove 4. Its inner arc surface tightly bites the hose braided layer, forming a multi-claw mechanical clamping. During the tightening process of the fixing sleeve 6, the fan-shaped fixing piece 5 first compresses the stainless steel braided hose 01. The stainless steel braided hose 01 then applies pressure to the Y-shaped inflatable rubber ring 10, causing it to deform. This compression and expansion fills the gap between the stainless steel braided hose 01 and the connecting groove 3, forming a seal to prevent the medium inside the stainless steel braided hose 01 from entering the connecting groove 3. Furthermore, when the Y-shaped inflatable rubber ring 10 deforms, the air inside the arc-shaped groove 1001 is squeezed out due to the compression of the inner wall of the stainless steel braided hose 01. Because the inner wall of the stainless steel braided hose 01 is smooth, a sealed space is formed between the arc-shaped groove 1001 and the inner wall surface of the stainless steel braided hose 01. The external atmospheric pressure is much greater than that of the arc-shaped groove at this time. The air pressure inside 1001 creates a pressure difference. The atmospheric pressure will press the arc-shaped groove 1001 tightly against the inner wall surface of the stainless steel braided hose 01, causing the Y-shaped inflatable rubber ring 10 to generate an adsorption force on the inner wall of the stainless steel braided hose 01, which greatly improves the sealing performance. At the same time, the annular inflatable rubber ring 11 is embedded in the gap between the fastening sleeve 6 and the connector body 1. As the threads are screwed in, it is compressed and expanded to fill the gap between the top and bottom of the threads, preventing the medium from leaking along the threads. This completes the fixed connection between the stainless steel braided hose 01 and the connector body 1. Then, the threaded sleeve 2 is screwed toward the external connector interface that needs to be connected. The sealing ring 12 on the inner wall of the threaded sleeve 2 contacts the sealing surface of the external connector to form a seal.When the stainless steel braided hose 01 is partially damaged or the connector body 1 needs to be replaced, loosen the threaded sleeve 2 in the reverse direction to disconnect it from the external connector. Then unscrew the fastening sleeve 6. The fan-shaped fixing piece 5 will automatically reset due to the material's elasticity, loosening the stainless steel braided hose 01. Cut off the damaged section of the stainless steel braided hose 01 and repeat the above installation steps to reassemble the remaining stainless steel braided hose 01, or replace it with a new connector body 1 for continued use. Through the design of this utility model, when the connector body 1 has problems such as leakage or stripped threads, it is not necessary to discard the stainless steel braided hose 01 along with it. The connector body 1 can be replaced separately simply by unscrewing. This saves on usage costs compared to the traditional "hose + connector" bundled replacement mode. In civilian scenarios, users can operate it themselves, and maintenance efficiency is also improved. This not only saves a lot of consumables and labor costs in the industrial field, but also promotes the upgrading of the fluid connection industry towards green and intelligent directions through modular design. It has broad application prospects in chemical, mechanical, kitchen and bathroom scenarios.
