[0032] In order to further explain the technical scheme of the utility model, the present application will be described in detail below through specific embodiments.

[0033] As Figs. 1 to 3As shown, it is a faucet rotating joint with good stability, which comprises an inner core pipe 1 and a rotating sleeve 2. The inner core pipe 1 is formed with a water passage 11, which is communicated with the water outlet pipe of the faucet and the water outlet of the faucet body. The outer wall of the inner core pipe 1 is formed with a limiting groove 12, and the inner wall of the rotating sleeve 2 is rotatably embedded in the limiting groove 12. The rotating sleeve 2 is rotatably integrally formed on the inner core pipe 1. In addition, the inner wall of the rotating sleeve 2 is formed with a limiting ring 21, which is embedded in the limiting groove 12. The rotating sleeve 2 is rotatably integrally formed on the inner core pipe 1, and the rotating sleeve 2 is rotatably embedded in the limiting groove 12, so that the rotating sleeve 2 is uniformly limited between the upper wall and the lower wall of the limiting groove 12. When the faucet water outlet pipe drives the rotating sleeve 2 to move, the stress between the rotating sleeve and the inner core pipe 1 is more balanced, so it has better stability and can prevent the structure of the rotating joint from deforming too much to cause water leakage.

[0034] Preferably, the inner core pipe 1 is detachably provided with a sealing seat 3, which is rotatably sleeved on the inner core pipe 1. The outer wall of the sealing seat 3 is formed with a sealing groove 31, and a sealing ring (not shown in the figure) is installed in the sealing groove 31. The sealing ring is sealed between the sealing seat 3 and the inner wall of the faucet water outlet pipe, and the sealing seat 3 can rotate with the faucet water outlet pipe, which further improves the sealing between the sealing seat 3 and the inner wall of the water outlet pipe and avoids the abrasion of the sealing ring caused by friction with the metal inner wall of the water outlet pipe. The detachable sealing seat 3 can also facilitate the installation of the gear device 4 between the sealing seat 3 and the rotating sleeve 2.

[0035] Preferably, as shown in Fig. 2 and Fig. 3 The sealing seat 3 is formed with a letting-in hole 32, and the inner core pipe 1 is formed with a letting-in groove 13. A limiting block 33 is inserted into the letting-in hole 32, and one end of the limiting block 33 is inserted into the letting-in groove 13. During installation, the sealing seat 3 is sleeved on the inner core pipe 1, and then the limiting block 33 is inserted into the letting-in hole 32, so that the limiting block 33 can be embedded in the letting-in groove 13. In addition, the sealing seat 3 and the inner core pipe 1 can also be sealed by a sealing ring.

[0036] Preferably, a gear shifting device 4 is detachably installed between the sealing seat 3 and the rotating sleeve 2. The gear shifting device 4 includes a gear shifting ring 41 and a gear shifting head 42. The gear shifting ring 41 is fixedly installed between the sealing seat 3 and the rotating sleeve 2. A plurality of gear shifting grooves 43 are formed on the gear shifting ring 41, and one end of the gear shifting head 42 abuts against any one of the gear shifting grooves 43. Preferably, an installation groove 22 is formed on the rotating sleeve 2, and the gear shifting head 42 is movably inserted into the installation groove 22. When the user rotates the faucet outlet pipe, it will drive the rotating sleeve 2 to move, thereby driving the gear shifting head 42 to rotate. This allows the gear shifting head 42 to abut against different gear shifting grooves 43, achieving a gear shifting feel. Preferably, a pre-tensioning spring 5 is installed between the lower end of the gear shifting head 42 and the installation groove 22, and the gear shifting head 42 can abut against the gear shifting groove 43 by the elastic force of the pre-tensioning spring 5. In addition, the gear shift device 4 is detachable. When the gear shift feel is not needed, the gear shift head 42 and the preload spring 5 used to press against the gear shift head 42 can be removed, which can easily meet the diverse needs of users.

[0037] Preferably, such as Fig. 3 As shown, a hexagonal boss 14 is formed on the inner core tube 1, and a hexagonal hole 44 is formed on the gear ring 41. The hexagonal boss 14 is inserted into the hexagonal hole 44. Preferably, other polygonal bosses can also be used on the inner core tube 1 to cooperate with the polygonal hole on the gear ring 41, restricting the rotation of the gear ring 41. This allows the gear head 42 and the gear ring 41 to move relative to each other, thereby achieving the gear feel during rotation.

[0038] Preferably, the inner core tube 1 is made of metal, and the rotating sleeve 2 is made of plastic. Preferably, the outer wall of the rotating sleeve 2 has a locking hole 23, and a locking nut 24 is disposed in the locking hole 23. The locking nut 24 is used to fix the faucet outlet pipe to the rotating sleeve 2. Preferably, the locking nut 24 is made of metal. The rotating sleeve 2 can be directly formed onto the inner core tube 1 and the locking nut 24 by an insert-type molding.

[0039] Preferably, a groove 25 is formed on the outer wall of the rotating sleeve 2; a plurality of supporting ribs 26 are formed on the lower part of the outer wall of the rotating sleeve 2, and the supporting ribs 26 are evenly arranged along the circumference of the outer wall of the rotating sleeve 2. The groove 25 makes the overall wall thickness of the rotating sleeve 2 more uniform during molding, avoids shrinkage and deformation after cooling, and further improves the stability of the rotary joint. The supporting ribs 26 are evenly arranged along the circumference of the outer wall of the rotating sleeve 2, and the supporting ribs 26 abut against the inner wall of the faucet outlet pipe, thus making the faucet outlet pipe more stable during installation.

[0040] Compared with the prior art, the faucet rotating joint with good stability is characterized in that the rotating sleeve 2 is directly rotatably formed in the limiting groove 12 of the inner core pipe 1, and the stability of the rotating joint connection is greatly improved.

[0041] The above embodiments and drawings are not limited to the product shape and style of the present application, and any appropriate changes or modifications made by any person skilled in the art shall be considered as not departing from the patent scope of the present application.
