Description

Technical Field

[0001] This utility model relates to the field of faucet connector technology, and more specifically, to a rotary connector and a water outlet device. Background Technology

[0002] Rotary joints are used for the rotatable connection between the outlet pipe and the outlet body or valve body, allowing the outlet pipe to rotate relative to the valve body. They typically include an inner core tube connected to the body or valve body, a connecting sleeve connected to the outlet pipe, and a sealing ring or seal.

[0003] Existing rotary joints can only fit a fixed-size water outlet pipe with their sealing rings or seals. When there is a deviation in the inner diameter of the section where the water outlet pipe mates with the sealing ring or seal, or when there is a deviation in the size of the sealing ring or seal, it will result in failure to seal or incomplete sealing, leading to water leakage.

[0030] Example

[0031] Combination Figures 1 to 8 As shown, this embodiment provides a rotary joint, including an inner core tube 1, and a connecting sleeve 2, a sealing element 3, and a limiting element 4 sequentially sleeved on the inner core tube 1;

[0032] The limiting member 4 is movably disposed at the upper end of the inner core tube 1; the sealing member 3 is disposed between the connecting sleeve 2 and the limiting member 4 to achieve a seal between the inner core tube 1 and the outlet pipe.

[0033] The limiting member 4 can be moved and adjusted along the axial direction of the inner core tube 1 to apply pressure to the sealing member 3, thereby adjusting the outer diameter of the sealing member 3.

[0034] Specifically, in this embodiment, such as Figure 4As shown, the upper end of the inner core tube 1 is provided with an external thread, and the limiting member 4 is provided with an internal thread and is screwed to the inner core tube 1 so that the limiting member 4 can be adjusted along the axial direction of the inner core tube 1.

[0035] like Figure 7 and Figure 8 As shown, in this embodiment, the sealing element 3 includes a main body 5, an inner sealing part 6 connected to the inner wall of the main body 5 in a complete circle, and three outer sealing parts 7 connected to the outer wall of the main body 5 in a complete circle for side sealing with the water outlet pipe; a sealing groove 8 adapted to the inner sealing part 6 is provided on the outer peripheral wall of the inner core tube 1. A limiting part is protruding from the upper and lower end faces of the main body 5; the upper end of the connecting sleeve 2 and the lower end of the limiting element 4 are provided in the first limiting groove adapted to the limiting part. The inner diameter of the main body 5 is larger than the outer diameter of the inner core tube 1, providing compression space for the main body 5 placed on both sides of the inner sealing part 6. In this embodiment, one of the outer sealing parts 7 in the middle is placed on the opposite outer side of the inner sealing part 6. Thus, when the sealing element 3 is compressed downward by the limiting part, at least the outer sealing part 7 in the middle can expand outward, thereby adapting to the water outlet pipe with a larger inner diameter.

[0036] When the inner diameter of the water outlet pipe deviates, or the size of the sealing ring or sealing element 3 deviates, the structure can be adapted by adjusting the position of the limiting element 4 to adjust the outer diameter of the sealing element 3.

[0037] Furthermore, such as Figures 4 to 6 As shown, the outer peripheral wall of the inner core tube 1 is provided with a full circle of second limiting grooves 10; the connecting sleeve 2 is provided with multiple retaining springs 11 that are adapted to the limiting grooves, and the retaining springs 11 are arranged to protrude upwards to achieve vertical force, thereby preventing the water outlet pipe from shifting upwards under water pressure, which would cause a large gap between the bottom end face of the water outlet pipe and the platform, body, or valve body, resulting in an uncoordinated appearance. Furthermore, the lower inner side of the support arm is provided with a guide surface 18 to facilitate the connecting sleeve 2 being fitted and snapped onto the inner core tube 1 from top to bottom.

[0038] In this embodiment, the inner core tube 1 includes a threaded section 12 at the bottom and a limiting step 13 connected to the threaded section 12; a chamber 14 is formed between the connecting sleeve 2 and the limiting step 13; a stop ring 15 is provided in the chamber 14, which is fixedly sleeved on the second limiting part 19 of the inner core tube 1, and a stop groove 16 is provided on its upper end face; the connecting sleeve 2 is provided with an installation groove 17, and an elastic element and a stop element adapted to the stop groove 16 are provided in the installation groove 17. When the connecting sleeve 2 rotates with the water outlet pipe, it can form a stop feel under the action of the spring, improving the user experience.

[0039] This utility model also provides a water outlet device, including a water outlet body and a water outlet pipe, wherein the water outlet pipe is connected to the water outlet body via the rotary joint. By providing the limiting member 4, if there is a deviation in the inner diameter of the water outlet pipe, or a deviation in the size of the sealing ring or sealing element 3, the position of the limiting member 4 can be adjusted to adjust the outer diameter of the sealing element 3 for adaptation.
