[0001] The utility model relates to the technical field of bathroom faucets, in particular to a rotary joint of a faucet. Background Art

[0002] The existing faucet has a mechanical arm assembled on the water outlet of the faucet. Through the relative rotation of multiple joints on the mechanical arm, the water outlet direction can be adjusted at multiple angles, which is very convenient to use. The water outlet on the existing mechanical arm is connected to the mechanical arm through a rotating structure. Figure 1 The rotating structure comprises an internal joint 10, a rotating sleeve 20, an outer shell 30 and a rivet positioning structure 40, wherein the internal joint 10 and the rotating sleeve 20 are tightly matched and rotated, and the outer wall of the rotating sleeve 20 is provided with a rivet countersunk hole 201, and the outer shell 30 is provided with a through hole 301, and the rivet 40 passes through the through hole 301 and is locked in the rivet countersunk hole 201 to fix the rotating sleeve 20 and the outer shell 30 together; when the user adjusts the water outlet position, the outer shell 30 is manually rotated to drive the rotating sleeve 20 to rotate relative to the internal joint 10, so that the position of the water outlet end can be adjusted, and then the water outlet position can be adjusted for the user to use; however, when the water outlet end 50 is positioned in one position for a long time, it will rotate by itself due to its own gravity (mainly the gravity of the rotating sleeve 20 and the outer shell 30), resulting in wear and loosening between the rotating sleeve 20 and the internal joint 10, and the water outlet end 50 cannot be positioned for use after a long time, and the use effect is not good, and the service life is short; the mechanical arm needs to be replaced later, and the maintenance cost is high.

[0003] In view of this, the designer has made in-depth considerations and actively researched, improved and trial-produced the present invention to address the many deficiencies and inconveniences caused by the imperfect structural design of the swivel joint of the above-mentioned faucet. Utility Model Content

[0016] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0017] See also Figure 2 The utility model discloses a rotary joint of a faucet, which includes an internal joint 1, a rotating sleeve 2, an outer shell 3 and a rivet 4. The rotating sleeve 2 is tightly matched with the rotating sleeve and is arranged on the outer ring wall of the internal joint 1, and the outer shell 3 is sleeved on the outer ring wall of the rotating sleeve 2; the rotating sleeve 2 is provided with a rivet screw hole 21 penetrating the inner and outer ring walls of the rotating sleeve 2, and the outer shell 3 is provided with a through hole 31 corresponding to the rivet screw hole 21, and the rivet 4 is passed through the through hole 31 and locked in the rivet screw hole 21; when the internal joint 1 and the rotating sleeve 2 become loose and cannot be positioned for use of the water outlet, the rivet 4 is rotated so that the inner end of the rivet 4 passes through the rivet screw hole 21 and presses against the outer ring wall of the internal joint 1.

[0018] The rotary joint of the faucet of the present invention is provided with rivet screw holes 21 penetrating the inner and outer ring walls of the rotary sleeve 2. The rivet 4 can not only fix the rotary sleeve 2 and the outer shell 3 together, but also facilitate the rotation of the outer shell 3 to drive the rotary sleeve 2 to rotate; moreover, when it is found that the water outlet end 5 cannot be positioned for use, the rivet 4 can be rotated inwardly to make the inner end of the rivet 4 abut against the internal joint 1, and the tightness between the internal joint 1 and the rotary sleeve 2 can be adjusted in real time to avoid looseness between the internal joint 1 and the rotary sleeve 2, so as to ensure that the water outlet end 5 can be positioned for use for a long time, thereby extending the rotary joint of the faucet. The service life of the faucet can be prolonged. In specific operation, the water outlet end 5 can be adjusted to the use position first, and then the inner end of the rivet 4 can be rotated to press against the internal joint 1, so that the internal joint 1 and the rotating sleeve 2 are tightly matched together to avoid relative rotation between the two, thereby ensuring that the water outlet end 5 can be positioned for use. When the user wants to adjust the water outlet position of the water outlet, the rivet 4 can be unscrewed to provide a clearance space for the internal joint 1 and the rotating sleeve 2 to rotate, and then the rivet can be tightened to press against the internal joint 1. There is no need to frequently replace the rotating joint of the faucet in the future, and the water outlet end 5 can be positioned for use, with low maintenance cost.

[0019] The outer ring wall of the internal joint 1 of the utility model is sleeved with a plastic clamping ring 6, and the inner end of the rivet 4 is pressed against the plastic clamping ring 6, which can prevent the rivet 4 from directly pressing against the metal internal joint 1, and prevent the two metal rivets 4 and the internal joint 1 from directly contacting and producing harsh sounds.

[0020] The plastic clamp ring 6 of the present invention is a C-shaped clamp ring; the plastic clamp ring 6 is conveniently sleeved on the internal joint 1, and the assembly is more convenient.

[0021] The outer ring wall of the internal joint 1 of the utility model is provided with a necking section 11 for clamping the plastic clamping ring 6; the necking section 11 can limit the position of the plastic clamping ring 6 to prevent the plastic clamping ring 6 from shifting on the internal joint 1, so that the rivet 4 can more accurately abut against the plastic clamping ring 6, avoid looseness between the internal joint 1 and the rotating sleeve 2, and ensure that the water outlet end 5 can be positioned for long-term use.

[0022] The ring wall of the plastic clamp 6 of the utility model is provided with a plurality of slots 61 for the rivets 4 to abut against; when the rivets 4 abut against the slots 61, the internal joint 1 and the rotating sleeve 2 can be restricted from relative rotation, thereby preventing the water outlet end 5 from being rotated artificially or unintentionally, and the positioning structure of the water outlet end 5 is more stable, thereby ensuring that the water outlet end 5 can be positioned for long-term use.

[0023] A limiting structure for limiting the rotation of the plastic clamp ring 6 and the internal joint 1 of the utility model is provided between the plastic clamp ring 6 and the internal joint 1 to prevent the plastic clamp ring 6 and the internal joint 1 from being worn and loosened, thereby preventing the water outlet from being unable to be positioned for water outlet use.

[0024] The above embodiments and drawings do not limit the product form and style of the utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the utility model.
