[0038] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0039] like Figure 1-Figure 7 As shown, this embodiment provides a faucet rotary joint, including a valve seat 10 and an inner core tube 20, the valve seat 10 is a plastic valve seat 10, the inner core tube 20 is a plastic inner core tube 20, the valve seat 10 and the inner core tube 20 are connected in one piece, it should be noted that in this embodiment, the upper part of the faucet after being installed on the countertop is the upper part of each component, and the lower part of the faucet after being installed on the countertop is the lower part of each component, an annular groove 21 is provided on the outer wall of the inner core tube 20, a rotating sleeve 22 is provided in the annular groove 21, the rotating sleeve 22 is rotatably connected to the inner core tube 20, the rotating sleeve 22 has a first notch 23 which is arranged parallel to the axis of the rotating sleeve 22 and passes through it from top to bottom, the rotating sleeve 22 is an elastic sleeve, and this arrangement is convenient for the rotating sleeve 22 to be put on It is arranged in the annular groove 21, and a gear sleeve 24 is also sleeved in the annular groove 21. The rotating sleeve 22 is located above the gear sleeve 24. Specifically, there is a gap between the upper end surface of the rotating sleeve 22 and the upper side wall of the annular groove 21, and the smaller the gap, the better. This can prevent the rotating sleeve 22 from rotating and sliding off the inner core tube 20. The lower end surface of the rotating sleeve 22 abuts against the upper end surface of the gear sleeve 24, and the lower end surface of the gear sleeve abuts against the lower side wall of the annular groove 21. The gear sleeve 24 is fixedly connected or integrally connected with an annular boss 25 inserted in the rotating sleeve 22, and the outer peripheral surface of the annular boss 25 is fixedly connected or integrally connected with a limiting protrusion 26 inserted in the first notch 23. This arrangement allows the gear sleeve 24 and the rotating sleeve 22 to rotate synchronously.

[0040] A positioning ring 27 is provided at one end of the valve seat 10 connected to the inner core tube 20, and a gear structure is provided between the positioning ring 27 and the gear sleeve 24. The gear structure includes a mounting groove 28 opened on the positioning ring 27, a spring 29 arranged vertically in the mounting groove 28, a gear protrusion 30 fixedly connected to one end of the spring 29 away from the bottom of the mounting groove 28, and a gear groove 31 matched with the plurality of gear protrusions 30. The gear grooves 31 are distributed around the lower end of the gear sleeve 24 with the axis of the gear sleeve 24 as the center.

[0041] The gear position projection 26 includes a circular column 40 and a conical head 41, and the circular column 40 and the conical head 41 are connected as one body. Specifically, the upper end of the circular column 40 is connected as one body with the large end of the conical head 41, and one end of the spring 29 is abutted against the bottom of the mounting groove 28, and the other end of the spring 29 is sleeved on the circular column 40, and the end of the spring 29 away from the mounting groove 28 is abutted against the end surface of the large end of the conical head 41, and the depth of the mounting groove 28 is adapted to the length of the spring 29, so that the conical head 41 can extend into the gear position groove 3 1, when the water outlet pipe rotates and drives the rotating sleeve 22 to rotate, the rotating sleeve 22 rotates and drives the limiting sleeve 24 to rotate, the gear projection 26 is pushed down by the limiting sleeve 24, and the conical head 41 slides out of the gear groove 31 until it passes through the next adjacent gear groove 31. Under the action of the spring 29, the conical head 41 slides upward into the gear groove 31 to prevent the water outlet pipe from continuing to rotate due to the rotation inertia force. At the same time, a knocking sound is generated when the conical head 41 slides into the gear groove 31, reminding the user that a gear has been rotated.

[0042] The interior of the inner core tube 20 is provided with a first water outlet hole 32 that runs through the inner core tube 20 and is coaxial with the inner core tube 20. The valve seat 10 has a valve core matching portion, and the valve core matching portion is provided with a cold water inlet hole 33, a hot water inlet hole 34 and a second water outlet hole 35 that match the valve core. It should be noted that the valve core is a conventional valve core, which will not be described in detail here. The valve core is not part of a faucet rotary joint provided in this embodiment and needs to be configured separately when used. Since the valve core is a standardized part, the setting positions of the cold water inlet hole 33, the hot water inlet hole 34 and the second water outlet hole 35 are also fixed. The first water outlet hole 32 and the second water outlet hole 35 are connected to each other. The interior of the valve seat 10 is provided with a first water inlet through hole 36 and a second water inlet through hole 37 that run downward. The first water inlet through hole 36 is connected to the cold water inlet hole 33, and the second water inlet through hole 37 is connected to the hot water inlet hole 34.

[0043] A plurality of sealing grooves 38 are provided on the outer wall of the inner core tube 10, and a sealing ring (not shown in the figure) is arranged in each sealing groove 38 to form multiple seals to prevent water leakage, wherein the groove width of the annular groove 21 is greater than the groove width of the sealing groove 38, and there is a spacing distance between adjacent sealing grooves 38, and the larger the spacing distance, the better the sealing effect.

[0044] A spring piece 50 is provided on the side wall of the rotating sleeve 22, and the connecting line between the spring piece 50 and the first notch 23 is located in the radial direction of the rotating sleeve 22. A connecting protrusion 51 is fixedly connected or integrally connected to the spring piece 50. It should be noted that the water outlet pipe is a conventional kitchen water outlet pipe, and the water outlet pipe is not a part of a faucet rotary joint provided in this embodiment, and needs to be configured separately when in use. A through hole is opened on the water outlet pipe. When in use, the water outlet pipe sleeve is arranged outside the rotating sleeve 22, and the connection can be completed by matching the connecting protrusion 51 with the through hole opened in the water outlet pipe. Of course, the valve seat 10 is outerly provided with an outer shell connected to the water outlet pipe. The outer shell needs to be a conventional kitchen outer shell. The specific structure of the connection between the water outlet pipe and the outer shell is all existing technology, which will not be described in detail here, and the outer shell is not a part of a faucet rotary joint provided in this embodiment, and needs to be configured separately when in use.

[0045] The gear sleeve 24 has a second notch 42 which is arranged parallel to the axis of the gear sleeve 24 and passes through the gear sleeve 24 from top to bottom. This arrangement makes it easy to sleeve the gear sleeve 22 in the annular groove 21 .

[0046] During installation, the gear sleeve 24 is first sleeved in the annular groove 21, and then the rotating sleeve 22 is sleeved in the annular groove 21. At this time, the limiting protrusion 26 is inserted in the first notch 23, which will limit the gear sleeve 24 from rotating relative to the rotating sleeve 22, that is, the rotating sleeve 22 drives the gear sleeve 24 to rotate relative to the inner core tube 10 at the same time, and then the seal 39 is sleeved in the sealing groove, and finally the water outlet pipe is sleeved outside the rotating sleeve 22, and the connection is completed by matching the connecting protrusion 51 with the through hole opened in the water outlet pipe. The utility model connects the valve seat 10 and the inner core tube 20 as a whole, so there is no need to perform threaded connection with the housing of the faucet or the inner tank of the faucet, the structure is simple, the sealing effect is good, and a gear structure is provided between the positioning ring 27 and the gear sleeve 24, a sound will be made when the faucet is turned, and the rotation feel is relatively good.
