[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1
[0019] like Figure 1 As shown, in this example, the rotating core of the shower corrugated pipe includes a fixed pipe 1 and a connecting pipe assembly 2 for connecting two fixed pipes 1, wherein the inner wall of the straight cylindrical fixed pipe 1 is in a two-stage stepped shape along the axial direction.
[0020] The connecting pipe assembly 2 includes a first pipe body 22, a second pipe body 21, and a collar 26. The peripheral walls of the first pipe body 22 and the second pipe body 21 are both in a three-stage stepped shape along the axial direction.
[0021] The collar 26 is fitted onto the tube body 22 near the beginning end, such as on the high stepped surface in the middle. The inner wall of the beginning end of the tube body 21 is formed with a threaded surface and engages with the threaded surface on the circumferential wall of the collar 26.
[0022] The inner diameter of the collar 26 is smaller than the outer diameter at the first end of the tube body 22. After the first end of the tube body 21 is fitted onto the first end of the tube body 22 and threadedly connected to the collar 26, the axial separation of the tube body 22 and the tube body 21 is restricted. The inner wall of the tube body 21 is in a two-stage stepped shape along the axial direction. A sealing ring 25 is placed in the gap between the cavity wall at the stepped split surface and the end face of the first end of the tube body 22. With this structure, the mutual rotational engagement between the tube body 1 and the tube body 2 is more flexible.
[0023] Both the secondary tube 21 and the primary tube 22 have threaded surfaces 23 formed on their central high-stepped surfaces. Corresponding threaded surfaces are formed on the high-stepped surfaces of the fixed tube 1, engaging with the threaded surfaces on the corresponding tubes. The fixed tubes 1 on both sides are respectively fitted onto the corresponding primary tube 22 and the secondary tube 21. A space for clamping the corrugated tube 3 is formed between the low-stepped surfaces of the secondary tube 22 and the secondary tube 21 and the low-stepped surfaces of the corresponding fixed tube 1.
[0024] like Figure 1 As shown, the fixing tube is pre-fitted onto the end of the corrugated pipe, and the end of the corrugated pipe 3 is fitted onto the tail ends of the corresponding pipe body 1 22 and pipe body 21. The fixing tube 1 is moved forward, and the low-level stepped surface of the cavity wall of the fixing tube 1 cooperates with the low-level stepped surface of the circumferential wall of the corresponding pipe body 1 and pipe body 2 to clamp the corrugated pipe 3 in the middle. Then, the threaded surface of the high-level stepped surface of the fixing tube is threadedly engaged with the threaded surface of the corresponding stepped surface of the corresponding pipe body 1 and pipe body 2, and the fixing tube is fixed to the corresponding pipe body 1 and pipe body 2.
[0025] In this example, a gap is reserved between the stepped interface at the periphery of the first end of tube 21 and the corresponding end face of the fixed tube 1, and a gap is also reserved between the first end face of tube 21 and the corresponding end face of the fixed tube 1, to reduce the impact on the rotational fit of tube 1 and tube 2. To reduce the entry of debris, decorative rings 4, such as rings made of rubber, are placed in the above two gaps in this example.
[0026] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
