Description

Technical Field

[0001] The utility model relates to the technical field of shower tube sets, in particular to a telescopic shower tube set and a shower device. Background Art

[0002] The structure of the retractable shower tube group of the existing shower device is as follows: a locking nut is threadedly connected to one end of the outer tube body, and one end of the inner tube body is retractably arranged inside one end of the outer tube body. An elastic seal is installed between the locking nut and the inner tube body. The elastic seal is squeezed and sealed between the outer tube body, the locking nut and the inner tube body by rotating and tightening the locking nut, thereby limiting the telescopic movement of the inner tube body inside the outer tube body. However, since the tube wall of the outer tube body serving as the fixed end is relatively thin, the extrusion contact area between it and the elastic seal is relatively small, and thus the stability and sealing of the inner tube body installed inside the outer tube body cannot be guaranteed. Under high water pressure, the locking nut is prone to loosening, causing the elastic seal to loosen, thereby causing the inner tube body and the outer tube body to loosen and leak easily.

[0027] See also Figure 1-5 As shown, as an embodiment of the utility model, a retractable shower tube set is provided, comprising an inner tube body 1 and an outer tube body 2 which are connected to each other, a locking assembly is installed on the outside of one end of the outer tube body 2, one end of the inner tube body 1 is plugged into the inside of one end of the outer tube body 2 to achieve telescopic fit, and an elastic sealing member 3 is installed between the locking assembly and the inner tube body 1;

[0028] The locking assembly includes an adapter 4 and a locking member 5. The adapter 4 is fixedly sleeved on the outside of one end of the outer tube body 2, and the locking member 5 is movably sleeved on the outside of the adapter 4. The locking member 5 moves toward the direction of the adapter 4 to achieve sealing and clamping of the elastic seal 3 between the outer tube body 2, the locking assembly and the inner tube body 1, thereby limiting the telescopic movement of the inner tube body 1 inside the outer tube body 2. On the contrary, when the locking member 5 moves in the direction away from the adapter 4, the space between the locking member 5 and the adapter 4 increases, thereby releasing the movable limit of the elastic seal 3 in the axial direction, thereby releasing the restriction on the telescopic movement of the inner tube body 1 inside the outer tube body 2.

[0029] The above technical scheme, by providing an adapter 4 on the external fixed sleeve at one end of the outer tube body 2, the adapter 4 and one end of the outer tube body 2 together serve as a fixed end that is extruded and contacted with the elastic seal 3. Compared with the existing technical scheme in which one end of the outer tube body is used as the fixed end alone, the fixed end of this scheme is thicker, so that the extrusion contact area between the fixed end and the elastic seal 3 is larger, and the elastic seal 3 is sealed and clamped between the outer tube body 2, the adapter 4, the locking member 5 and the inner tube body 1, thereby ensuring the stability and sealing of the inner tube body 1 installed inside the outer tube body 2. Under high water pressure, the locking assembly is not easy to loosen and cause the elastic seal 3 to loosen, thereby making it difficult for the inner tube body 1 and the outer tube body 2 to loosen and leak, and the assembly effect and use process are more stable and reliable.

[0030] In this embodiment, an external plug-in thread is provided on the outer side of one end of the outer tube body 2, and an internal transfer thread and an external transfer thread are respectively provided on the inner and outer sides of the adapter 4, and an adjusting internal thread is provided on the inner side of the locking member 5. The internal transfer thread and the external plug-in thread are screwed together to realize that the adapter 4 is fixedly sleeved on the outside of one end of the outer tube body 2, and the external transfer thread and the adjusting internal thread are screwed together to realize that the locking member 5 is movably sleeved on the outside of the adapter 4, that is, the adapter 4 is an adapter nut, and the locking member 5 is a locking nut, and a flat cut surface 53 is formed on the circumferential outer side of the locking member 5, which is convenient for users to hold and rotate. This arrangement makes the installation operation between the components easier and more convenient, and the assembly effect is more firm and stable.

[0031] In this embodiment, one end of the adapter 4 close to the locking member 5 extends radially inward to form a first blocking portion 41, and the first blocking portion 41 cooperates with the axial limiting port at one end of the outer tube body 2 to ensure that the adapter 4 can be stably installed at the port at one end of the outer tube body 2.

[0032] In this embodiment, the elastic sealing member 3 is an elastic ring, which includes a conical ring portion 31. The outer diameter of the conical ring portion 31 gradually decreases from the locking member 5 toward the adapter 4. A guide conical surface 42 corresponding to the conical ring portion 31 is formed on the inner side of the end of the first blocking portion 41 away from the outer tube body 2. The guide conical surface 42 is squeezed and matched with the conical ring portion 31, that is, when the locking member 5 moves toward the adapter 4, it drives the elastic sealing member 3 to move in the direction of the adapter 4, so that the guide conical surface 42 is squeezed and matched with the conical ring portion 31, so that the ring is retracted and clamped between the outer tube body 2, the locking assembly and the inner tube body 1, thereby limiting the telescopic movement of the inner tube body 1 inside the outer tube body 2.

[0033] In this embodiment, the inner diameter of the first blocking portion 41 is larger than the inner diameter of the outer tube body 2, and a gap 6 is formed between the outer tube body 2 and the inner tube body 1. The smaller end of the conical ring portion 31 is clamped and inserted in the gap 6. This arrangement can further improve the sealing and fastening effect between the outer tube body 2 and the inner tube body 1.

[0035] In this embodiment, the collar also includes a column ring portion 32 located at the end of the conical ring portion 31 away from the adapter 4. The end of the locking member 5 away from the adapter 4 extends radially inward to form a second blocking portion 51. The inner side of the second blocking portion 51 is formed with an annular step 52 corresponding to the column ring portion 32. The annular step 52 is used to block and limit the column ring portion 32 in the axial and radial directions, so as to ensure the sealing and installation stability of the collar in the locked state.

[0036] In this embodiment, a sealing tube 7 is also included. The outer wall of one end of the sealing tube 7 is sealed with the inner wall of the outer tube body 2 via a sealing ring, and the outer wall of the other end of the sealing tube 7 is sealed with the inner wall of the inner tube body 1 via a sealing ring. The inner tube body 1 and the outer tube body 2 are connected via the sealing tube 7. This arrangement further improves the sealing effect between the outer tube body 2 and the inner tube body 1.

[0037] In this embodiment, the outer tube body 2 includes a vertical tube 21 and a horizontal tube 22 which are L-shaped. One end of the inner tube body 1 is inserted into the interior of the end of the horizontal tube 22 away from the vertical tube 21 to achieve telescopic fit, so that the inner tube body 1 can be telescopically adjusted in the horizontal space.

[0038] See also Figure 6 As shown, the utility model also provides a shower device, including the retractable shower tube group described in the above embodiment, and also including a top spray shower head 8. The outer tube body 2 includes a vertical tube 21 and a horizontal tube 22 which are L-shaped to each other. The vertical tube 21 is connected to a water inlet pipe, and the inner tube body 1 is connected to the end of the horizontal tube 22 away from the vertical tube 21. The top spray shower head 8 is connected to the water outlet end of the inner tube body 1.
