[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1 , 2 As shown, an anti-detachment structure of a shower pipe comprises a stainless steel double-buckle pipe 1 and a flange liner 5, the flange liner 5 comprises a connecting pipe and a flange located at one end of the connecting pipe, an external thread is arranged on the outer circumference of the end of the connecting pipe away from the flange, and the outer circumference of the end of the connecting pipe provided with the flange is smooth, both ends of the double-buckle pipe 1 are respectively threadedly connected to the corresponding connecting pipe of the flange liner and the ends thereof are abutted against the flange of the flange liner 5, both ends of the double-buckle pipe 1 are also respectively sleeved with a first steel sleeve 4, one end of the first steel sleeve 4 is abutted against the flange of the flange liner, the first steel sleeve 4 is buckled and connected to the double-buckle pipe 1, and a second steel sleeve 3 is also sleeved outside the first steel sleeve 4, and the inner wall of the second steel sleeve 3 is in contact with the outer wall of the first steel sleeve 4.

[0019] Through the above structure, a certain space is reserved between the thread length of the connecting pipe of the flange liner 5 and the flange, the double-buckle tube 1 is rotated onto the flange liner 5, and the end of the double-buckle tube 1 is pressed against the flange of the flange liner 5. The threads of the double-buckle tube outside the smooth connecting pipe of the flange liner 5 are closed to form a self-locking function, which has a certain anti-slip function. On this basis, the spiral structure of the double-buckle tube located on the smooth part of the connecting pipe is destroyed by the first steel sleeve 4 buckled with the connecting pipe, thereby improving the anti-slip effect.

[0020] As an implementation mode, the first steel sleeve 4 is a stamped steel sleeve, the second steel sleeve 3 is a flanged steel sleeve, and one end of the flange of the second steel sleeve 3 abuts against the flange.
