[0034] Combination Figures 1 to 8 This embodiment provides a faucet that is easy to assemble and disassemble, including a bend 1, a main body 2, and an installation structure for connecting the bend 1 and the main body 2. The installation structure includes a bushing 3 fixed to the bottom end of the bend 1, a support member 4 for fixing to the main body 2, and an accessory 5 sleeved on the outer periphery of the support member 4 and rotatably connected to the support member 4. Specifically, the top of the bushing 3 is provided with a first locking part 31, and the inner wall of the bushing 3 is provided with a first guide part 32. The outer wall of the accessory 5 is provided with a second locking part 51 and a second guide part 52. The first guide part 32 is inserted along the second guide part 52, and the first locking part 31 and the second locking part 51 are engaged, thereby making the bend 1 rotatably connected to the main body 2. During installation, the bushing 3 with the first guide portion 32 is inserted into the assembly 5 with the second guide portion 52. When the first locking portion 31 and the second locking portion 51 engage, the bent tube 1 fixed to the bushing 3 is axially limited. Since the support member 4 is fixed to the main body 2, the assembly 5 is rotatably mounted on the support member 4, thus the bent tube 1 can rotate relative to the main body 2. During disassembly, simply hold the bent tube 1 and pull the bushing 3 off the assembly 5.

[0035] It should be noted that in this embodiment, the installation structure adopts an internal plug-in engagement method, which is convenient for assembly and disassembly without the need for wrenches or other installation tools, thus reducing the cost of installation tools. At the same time, there is no need to set assembly holes on the outer wall of the bend 1 or the main body 2, thereby ensuring the aesthetic appearance of the faucet. This avoids the impact of assembly holes on surface treatment, improving the product yield. In summary, compared with existing technologies, the installation structure does not damage the product's appearance and is easy to assemble and disassemble. The bend 1 and the main body 2 are separated at the factory to reduce the faucet's packaging volume and lower logistics costs. During installation, the bend 1 is simply plugged into the main body 2, which is convenient and quick.

[0036] In a preferred embodiment, the top of the bushing 3 narrows inward to form a first locking portion 31 to facilitate mold opening, reduce mold core pulling, and thus reduce mold costs.

[0037] In one embodiment, the first guide portion 32 includes a positioning section 321 adapted to the second guide portion 52, and an inclined section 322 connected to the first locking portion 31. The second locking portion 51 is configured to slide along the inclined section 322 toward the first locking portion 31. This ensures smooth insertion of the bushing 3 and the fitting 5, reduces the operating force during installation, and further facilitates the installation of the bent pipe 1. Preferably, the second locking portion 51 has a triangular cross-sectional shape to reduce resistance when it passes through the first locking portion 31.

[0038] Preferably, the top of the assembly 5 is provided with an elastic wall 53, the second locking portion 51 is formed on the outer side of the elastic wall 53, and the limiting portion 54 for connecting with the support member 4 is formed on the inner side of the elastic wall 53. For example, the assembly 5 has multiple clearance grooves 55 along the circumferential direction, and the wall surface between two adjacent clearance grooves 55 constitutes the elastic wall 53. Multiple second locking portions 51 are spaced apart along the circumferential direction to ensure balanced force distribution on the mounting structure. It is easily understood that the elastic wall 53 allows the first locking portion 31 to deform inwards when passing upwards through the first locking portion 31, and to spring back after exiting the first locking portion 31, thereby engaging the first locking portion 31 with the second locking portion 51. Ensuring smooth engagement between the second locking portion 51 and the first locking portion 31, and providing both the second locking portion 51 and the limiting portion 54 on the elastic wall 53, simplifies the assembly structure and makes the structure of the assembly 5 simpler.

[0039] Furthermore, the elastic wall 53 is configured to be at least partially higher than the top surface of the support member 4 to ensure the elasticity of the elastic wall 53. The support member 4 enhances the strength of the elastic wall 53, ensuring its resilience and preventing breakage during insertion.

[0040] For example, both the support member 4 and the assembly 5 are cylindrical. One end of the support member 4 is provided with a threaded portion 41. The support member 4 is fixed to the main body 2 by a threaded connection. At least two sealing rings are provided between the support member 4 and the assembly 5, which can produce a sealing effect and provide a better rotation feel to improve the user experience. At the same time, before the bend 1 is assembled with the main body 2, the sealing rings are covered by the assembly 5, which can prevent the lubricating oil on the sealing rings from soiling the product or the user's clothing. An internal hexagonal hole can also be provided on the support member 4, allowing the support member 4 to be tightened onto the main body 2 with a wrench. The fixing of the support member 4 can be done before leaving the factory, but is not limited to this. The support member 4 can also be fixed to the main body 2 by welding, without specific limitation. In addition, the design of the support member 4 can also prevent the hose passing through the support member 4 from getting tangled when rotating with the bend 1.

[0041] In another embodiment, the limiting part 54 protrudes along the inner side of the elastic wall 53, and the outer wall of the support member 4 is provided with a groove 42, which engages with the limiting part 54. The limiting part 54 can be configured as a snap-fit, which engages with the groove 42 to limit the assembly 5 axially. The snap-fit ​​connection facilitates the assembly 5 and the support member 4 to be assembled and disassembled.

[0042] Based on the above embodiments, in an optional embodiment of this utility model, the bushing 3 is provided with a plurality of first guide portions 32, each first guide portion 32 being configured as a groove with a decreasing cross-section from bottom to top, and a second guide portion 52 being provided as a protrusion along the inner wall of the fitting 5, and having a similar shape to the first guide portion 32. The first guide portion 32 and the second guide portion 52 are fitted together to limit the bushing 3 and the fitting 5 in the circumferential direction, thereby allowing the fitting 5 to rotate around the support member 4 to facilitate adjustment of the water outlet angle of the bend 1. The cross-section of the first guide portion 32 is configured to be larger at the bottom and smaller at the top, which facilitates the insertion of the second guide portion 52 from its bottom end and makes it easy for the first guide portion 32 and the second guide portion 52 to be aligned.

[0043] In other embodiments, the outer wall of the bushing 3 is provided with a plurality of ribs 33 at intervals, each rib 33 being interference-fitted with the bend 1, and each rib 33 having a guide surface 331 inclined in the assembly direction at its top to facilitate the insertion of the bushing 3 into the bend 1. Not limited to this, the bushing 3 can also be fixed to the bend 1 by adhesive or welding. It should be noted that in this embodiment, sealing elements are provided between the bushing 3 and the bend 1, between the support member 4 and the main body 2, and between the assembly 5 and the support member 4. The wall surface of the assembly 5 and the bushing 3 is sealed to prevent external water from entering the faucet.

[0044] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
