[0002] Faucet hose connectors are standardized accessories used to connect faucets and hoses. They are widely used in home, commercial and industrial settings. They come in various types, and their core functions include secure connection and leak-proof sealing. They are suitable for kitchens, bathrooms, garden irrigation, high-pressure cleaning and other scenarios. They are easy to install and have low maintenance costs, making them a key component of modern water systems.

[0003] Current faucet connectors have the following drawbacks: existing connectors mostly rely on additional fasteners to fix them to the faucet outlet, increasing the number of parts and assembly complexity. This structure means that the connection and separation of the connector and the faucet must be done with additional tools such as screwdrivers, and it is impossible to operate without tools, which brings significant inconvenience to installation and subsequent maintenance. Furthermore, the sealing of existing connectors is simple, and water can easily leak from the gap between the connector and the faucet outlet or the gap between the connector and the hose. Therefore, a hose connector for faucets is proposed to address the above problems. Utility Model Content

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.

[0016] Specific implementation examples are given below.

[0017] Please see Figures 1-2 The present invention provides a flexible hose connector for faucets, comprising: The fixing sleeve 1 is used to connect with the outlet 01 of the faucet 200. The fixing sleeve 1 is provided with a curved part 102 that cooperates with the outlet 01. When the fixing sleeve 1 is fitted onto the outlet 01, the curved part 102 and the curved area of ​​the outlet 01 form a mechanical lock. The sealing hose 2 is set in the limiting groove 101 opened in the inner wall of the fixed sleeve 1; The connecting sleeve 3 is connected to the fixing sleeve 1 by threaded engagement. The assembly end of the connecting sleeve 3 is provided with a groove 303 with internal threads, and the assembly end of the fixing sleeve 1 is provided with an inset part 103 that engages with and is embedded in the groove 303. Connecting pipe 4 is installed inside connecting sleeve 3 for connecting water pipe 100; A clamping sleeve 5 is disposed between the connecting sleeve 3 and the water pipe 100. The connecting sleeve 3 includes a kit 03 whose bottom end is fixed by a thread. The clamping sleeve 5 is located in an arc-shaped cavity 302 opened inside the kit 03. The middle part of the clamping sleeve 5 is an arc-shaped protrusion 501. The edge of the arc-shaped cavity 302 is provided with an arc-shaped bevel 3021 for pushing the arc-shaped protrusion 501 so that the clamping sleeve 5 tightly presses the water pipe 100 against the outer wall of the connecting pipe 4. The connecting sleeve 3 is provided with a boss 301 for placing the connecting pipe 4. The connecting pipe 4 is provided with a hanging ring 401 located above the boss 301. When the fixing sleeve 1 and the connecting sleeve 3 are assembled, the boss 301 applies pressure to the hanging ring 401, causing the hanging ring 401 to press against the clamping sleeve 5, causing it to deform and fit tightly against the water pipe 100 and the connecting pipe 4. When the fixing sleeve 1 and the connecting sleeve 3 are connected and fixed, the sealing hose 2 is deformed under pressure, causing its inner wall and outer wall to fit tightly against the outer wall of the outlet 01 and the inner wall of the fixing sleeve 1, respectively. At the same time, the clamping sleeve 5 is deformed under pressure, causing the water pipe 100 and the connecting pipe 4 to fit tightly. During operation, the sealing hose 2 is first placed into the limiting groove 101 of the fixing sleeve 1, and then the fixing sleeve 1 is fitted onto the outlet 01 of the faucet 200. At this time, the bent part 102 of the fixing sleeve 1 and the bent area of ​​the outlet 01 form a mechanical lock, initially limiting the relative displacement between the fixing sleeve 1 and the outlet 01 and preventing the fixing sleeve 1 from falling off along the outlet 01. Next, the connecting pipe 4 is placed on the boss 301 of the connecting sleeve 3, and then the connecting sleeve 3 is rotated through the threaded engagement. The inner part 103 of the fixing sleeve 1 gradually embeds into the groove 303 of the connecting sleeve 3. As the fixing sleeve 1 and the connecting sleeve 3 are continuously tightened, the limiting groove 101 will be squeezed. The inner sealing hose 2 undergoes elastic deformation, with its inner wall tightly fitting the outer wall of the faucet outlet 01, and its outer wall tightly fitting the inner wall of the limiting groove 101. During this process, the limiting groove 101 restricts the position of the sealing hose 2 to prevent it from coming out of the top opening of the fixing sleeve 1 under pressure. When the fixing sleeve 1 and the connecting sleeve 3 are fully tightened and fixed, the boss 301 of the connecting sleeve 3 applies upward pressure to the hanging ring 401 of the connecting pipe 4 to complete the seal between the faucet and the fixing sleeve 1. Then, the fitting 03 is inserted into the connecting end of the water pipe 100, so that the end of the water pipe 100 passes through the arc-shaped cavity 3 of the fitting 03. 02. Then, the clamping sleeve 5 is placed on the connecting end of the water pipe 100 to initially fix it to the end of the water pipe 100. Then, the water pipe 100 is inserted from the bottom end of the connecting pipe 4. Next, the kit 03 is moved to the bottom end of the connecting sleeve 3 and rotated to make it threadedly connected with the connecting sleeve 3. The kit 03 is continuously rotated, and the arc-shaped bevel 3021 of the arc-shaped cavity 302 generates a lateral thrust on the arc-shaped protrusion 501 of the clamping sleeve 5, causing the clamping sleeve 5 to undergo radial contraction deformation. Finally, the water pipe 100 is tightly fitted to the outer wall of the connecting pipe 4, and the double seal between the water pipe 100 and the connecting pipe 4, and between the faucet outlet 01 and the fixing sleeve 1 is achieved. Once fixed in place, water can flow smoothly from faucet 200 outlet 01, fixing sleeve 1, connecting pipe 4, and water pipe 100 after faucet 200 is turned on. Through the design and coordination of the above structure, the mechanical locking of the bending part 102 and the bending area of ​​outlet 01 allows the connector to be fixed at outlet 01 of faucet 200 without the use of additional fasteners, making installation more convenient and quick. The entire assembly process only requires rotating the connecting sleeve 3 to complete the thread engagement with fixing sleeve 1 and kit 03, without the need for additional tools such as screwdrivers. Furthermore, since the direction of water flow is vertical after faucet 200 is turned on, fixing sleeve 1 will not come off. Simultaneously, during the assembly process of the fixed sleeve 1 and the connecting sleeve 3, the sealing hose 2 is driven to fit in both directions to achieve the seal between the outlet 01 and the fixed sleeve 1. The connection between the connecting sleeve 3 and the kit 03 is synchronized to increase the deformation of the clamping sleeve 5 and enhance the seal between the connecting pipe 4 and the water pipe 100. All components are assembled and fixed and sealed synchronously through structural linkage.

[0018] Furthermore, the contact surface between the connecting pipe 4 and the inner wall of the water pipe 100 is provided with a conical protrusion 402. During operation, when the clamping sleeve 5 contracts and deforms under the thrust of the arc-shaped bevel 3021, the inner wall of the water pipe 100 is pushed towards the outer wall of the connecting pipe 4 by the clamping sleeve 5. At this time, the conical protrusion 402 on the connecting pipe 4 will fully contact the inner wall of the water pipe 100. Since the water pipe 100 is made of elastic material, the tip of the conical protrusion 402 will slightly embed into the inner wall of the water pipe 100, forming a physical interlocking structure, which restricts the relative sliding between the water pipe 100 and the connecting pipe 4. At the same time, the gap between the conical protrusions 402 can fill the small unevenness of the inner wall of the water pipe 100, reduce the leakage channel between the contact surface of the connecting pipe 4 and the water pipe 100, and further optimize the sealing effect.

[0019] Furthermore, a sealing ring 6 is provided between the groove 303 and the embedded part 103. During operation, when the embedded part 103 of the fixing sleeve 1 is inserted into the groove 303 of the connecting sleeve 3 and tightened by threads, the bottom end of the embedded part 103 and the inner wall of the groove 303 will exert a squeezing effect on the sealing ring 6, causing the sealing ring 6 to undergo elastic deformation. The deformed sealing ring 6 will fill the fitting gap between the embedded part 103 and the groove 303, forming a sealing barrier. The sealing ring 6 can prevent water from leaking to the outside from the gap between the embedded part 103 and the groove 303.

[0020] Furthermore, the outer wall diameter of the fixing sleeve 1 is the same as that of the connecting sleeve 3 and the kit 03. During operation, when the fixing sleeve 1, the connecting sleeve 3, and the kit 03 are fully assembled by threads, since the outer wall diameters are the same, there are no steps or protrusions at the connection, making the overall appearance of the connector more regular.
