The outlet pipe is provided with a connecting through hole at a position corresponding to the positioning component 131 , and screws, pins or positioning columns are inserted into the connecting through hole and the positioning component 131 for threaded connection to achieve connection and fixation between the outlet pipe and the rotating sleeve 13 .

[0035] The upper part of the inner core 1 is also sleeved with a sealing component 2. Specifically, the sealing component 2 includes a sealing sleeve 21 that is inserted into the inner core 1 and a snap ring 22 that is used to clamp and fix the sealing sleeve 21 on the inner core 1. The bottom of the sealing sleeve 21 abuts against the top of the rotating sleeve 13 to form a seal to prevent water from penetrating between the inner core 1 and the rotating sleeve 13. An outer sealing ring 211 is integrally formed on the outer side of the sealing sleeve 21 to form a seal with the water outlet pipe of the faucet. Compared with the prior art, the integrally formed outer sealing ring 211 has better overall sealing performance, is not easy to lose, and is easy to assemble. The snap ring 22 It includes a truncated cone 221 at the top and a plurality of claws 222 extending downward from the bottom of the truncated cone 221. The sealing sleeve 21 is provided with a channel 212 for the claws 222 to extend into at the position corresponding to each claw 222. The truncated cone 221 is hollow. After the claws 222 extend into the channel 212, the inner side wall of the truncated cone 221 is in close contact with the sealing sleeve 21. The claw 222 includes a claw arm 223 and a claw head 224 integrally formed at the bottom of the claw arm 223. A space for the claw head 224 to extend out is correspondingly provided on the inner side wall of the sealing sleeve 21. An annular groove 14 for the claw head 224 to be clamped is provided on the upper part of the inner core 1.

[0036] Specifically, two bosses 15 arranged at intervals in the upper part of the inner core 1 are provided, and an annular groove 14 is formed between the two bosses 15. The inner side wall of the bottom of the sealing sleeve 21 abuts against the outer side wall of the lower boss 15 to form a seal to prevent water from penetrating between the inner core 1 and the sealing sleeve 21. Preferably, the bottom of the claw arm 223 is inclined inwardly to make the installation more secure. A plurality of claws 222 are arranged in a circular array around the center of the truncated cone 221, and the bottom of the claw head 224 is provided with a chamfer to facilitate the claws 222 to be more conveniently inserted into the channel 212 at the top of the sealing sleeve 21. The sealing sleeve 21 of the utility model is made of conventional rubber material, and the buckle ring 22 is made of conventional elastic material with a certain strength, so that the buckle ring 22 has a certain tension, which is convenient for installation.

[0037] When in use, the sealing sleeve 21 is first sleeved on the upper part of the inner core 1, and then the claws 222 of the snap ring 22 are extended into the sealing sleeve 21 from the channel 212 at the top of the sealing sleeve 21, and the snap ring 22 is clamped on the annular groove 14 of the inner core 1 through the claws 224, so that the sealing assembly 2 is formed. With this structure, the assembly is firm and the two are not easy to separate;

[0038] A gear prompt assembly 3 is provided between the rotating sleeve 13 and the gear ring 12. The gear prompt assembly 3 includes a spring 31 fixedly connected to the rotating sleeve 13 at the upper end, a marble 32 fixedly installed at the lower end of the spring 31, and a plurality of gear holes 33 distributed in an annular manner on the upper end surface of the gear ring 12 and located below the marble 32 for embedding the marble 32. Specifically, an annular step is provided on the inner side of the rotating sleeve 13, and the annular step is located above the gear hole 33. A fixing column 30 is extended downwardly from the annular step. The spring 31 is sleeved on the fixing column 30, so that the spring 31 and the marble 32 are located above the gear hole 33. One end of the spring 31 abuts on the annular step, and the other end abuts on the marble 32. When the rotating sleeve 13 is rotated and the gear hole 33 is not located below the marble 32, the marble 32 will squeeze the spring 31 to contract. When the rotating sleeve 13 continues to rotate and the gear hole 33 is located just below the marble 32, the spring 31 will pop out the marble 32, and the marble 32 is embedded in the gear hole 33 under the action of the spring 31. The marble 32 collides with the gear hole 33 to make a sound, thereby serving as a prompt.

[0039] The buckle-type faucet rotary joint of the utility model has a simple structure. By setting the sealing component 2, the outer sealing ring 211 is integrally formed on the sealing sleeve 21, and the sealing sleeve 21 is fixed to the inner core 1 by the clamping cooperation of the buckle ring 22 and the sealing sleeve. The overall sealing performance is better and it is easy to assemble, which solves the problem that the prior art needs to achieve the sealing effect by setting a plurality of scattered outer sealing rings, which not only involves a large number of parts and complex assembly, but also the large number of small sealing rings is prone to hidden damage and water leakage during assembly.

[0040] The snap ring 22 and the sealing sleeve 21 are fitted together. With this structure, the snap ring 22 can be assembled flexibly and installed firmly. The sealing component 2 and the inner core 1 are not easy to separate, and the sealing and stability are good.
