[0019] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See also Figure 1-Figure 4 A faucet, the faucet comprises a faucet body 1, a threaded tube 2 and a limiting structure. The faucet body 1 is a three-way tube structure, the threaded tube 2 is a tubular structure, the lower end of the faucet body 1 includes an internal thread 11, the upper end of the threaded tube 2 includes an external thread 21, the limiting structure comprises a first limiting block 31 and a second limiting block 32, the first limiting block 31 is arranged at the lower end of the faucet body 1, the second limiting block 32 is arranged on the threaded tube 2 and is located below the external thread 21; when the external thread 21 of the threaded tube 2 is screwed into place corresponding to the internal thread 11 of the faucet body 1, the second limiting block 32 abuts against the first limiting block 31 to limit the rotation of the threaded tube 2.

[0021] The first limit block 31 and the second limit block 32 may have various structures. Two structures are listed below:

[0022] The first structure

[0023] The first stopper 31 is a first pin body inserted into the faucet body 1, and the second stopper 32 is a second pin body inserted into the outside of the threaded tube 2. A flange portion 12 is formed at the lower end of the faucet body 1, and the first pin body is vertically inserted into the lower side of the flange portion 12; the second pin body is horizontally inserted into the threaded tube 2.

[0024] The first pin body is a cylindrical structure, and a first pin hole is formed on the lower side of the flange part 12 of the faucet body 1. The first pin body can be embedded in the first pin hole by knocking, and the lower end of the first pin body extends out of the lower side of the flange part 12. Similarly, the second pin body is a cylindrical structure, and a second pin hole is formed on the lower side of the external thread 21 of the threaded tube 2, and the second pin body can be embedded in the second pin hole by knocking. The outer end of the second pin body extends out of the threaded tube 2. During installation, the upper end of the threaded tube 2 is screwed upward to the internal thread 11 of the faucet body 1 through the external thread 21, and the second pin body rises with the threaded tube 2 until the second pin body abuts against the first pin body, and the axial movement between the two is restricted.

[0025] The second structure

[0026] The first stopper 31 is integrally formed at the lower end of the faucet body 1; the second stopper 32 is integrally formed on the threaded tube 2. The first stopper 31 is formed on the faucet body 1 by machining, injection molding or stamping and flanging; the second stopper 32 is formed on the threaded tube 2 by machining, injection molding or stamping and flanging.

[0027] The threaded tube 2 has an opening 22 below the external thread 21, and the second stopper 32 is radially turned outward from the upper edge of the opening 22. The second stopper 32 includes a support block 322 extending downward and a radial block 323 connected to the lower end of the support block 322, and the radial block 323 is used to abut against the first stopper 31. A flange portion 12 is formed at the lower end of the faucet body 1, and the flange portion 12 forms a circumferential groove 121. The distance between the radial block 323 and the axis of the threaded tube 2 is less than or equal to the radius of the circumferential groove 121.

[0028] During installation, the upper end of the threaded tube 2 is screwed upward to the internal thread 11 of the faucet body 1 through the external thread 21, and the second limit block 32 rises with the threaded tube 2 until the second limit block 32 abuts against the first limit block 31, and the axial movement between the two is restricted.

[0029] The above is only a preferred specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the utility model within the technical scope disclosed by the utility model shall be deemed to infringe the protection scope of the utility model.
