[0028] The following describes the specific embodiments of the present utility model with reference to the drawings.

[0029] As shown Figure 7 in the drawings, a telescopic and rotatable connecting pipe fitting includes an upper shell 1, a telescopic tube 3 and a water outlet part 5.

[0030] As shown Figures 1 to 4As shown in the figure, a water outlet member 5 is provided at the bottom of the upper shell 1, and the water outlet member 5 is detachably connected to the upper shell 1. Specifically, a receiving space 14 that is recessed upward is provided at the bottom of the upper shell 1. A number of clamping blocks 13 are provided on the inner wall of the receiving space 14. On the outer wall of the top of the water outlet member 5, a fixing groove 22 and a mounting groove 21 are successively provided from top to bottom. A number of clamping portions 23 are provided in the fixing groove 22. The space formed between the clamping portion 23 and the fixing groove 22 forms a clamping slot 24. In the assembled upper shell 1 and water outlet member 5, the bottom of the upper shell 1 is placed in the mounting groove 21, the clamping blocks 13 are placed in the fixing groove 22, and the clamping blocks 13 are rotated along the fixing groove 22 and then embedded in the clamping slot 24. During assembly, the upper shell 1 is sleeved on the outer side of the top of the water outlet member 5, so that the bottom of the upper shell 1 is placed in the mounting groove 21. At the same time, the clamping blocks 13 are placed in the fixing groove 22. Then, the water outlet member 5 is rotated to make the clamping blocks 13 rotate along the fixing groove 22 and embed in the clamping slot 24. By using the limiting effect of the clamping slot 24 wall on the side wall of the clamping block 13, it is difficult to directly pull apart and separate the lower shell 2 and the water outlet member 5, so that the lower shell 2 and the water outlet member 5 are assembled together for use.

[0031] Among them, as shown in the attached Figure 3 、 Figure 4 and Figure 7 figures, the mounting groove 21, the fixing groove 22, the clamping portion 23 and the clamping slot 24 are provided on the outer wall of the top of the lower shell 2, and the lower shell 2 is connected to the water outlet member 5. Specifically, a connecting pipe 26 is provided at the bottom of the lower shell 2. An external thread is provided on the outer wall of the connecting pipe 26. The water outlet member 5 is threadedly connected to the connecting pipe 26. During the process, the upper shell 1 and the water outlet member 5 are spliced and assembled through the lower shell 2. Further, as shown in the attached Figure 3 figure, a number of inwardly recessed grooves 25 are provided on the outer wall of the bottom of the lower shell 2. The provision of the grooves 25 makes the outer wall of the bottom of the lower shell 2 uneven, which can enhance the friction between the lower shell 2 and the hand, and it is not easy to slip when rotating the lower shell 2, facilitating the assembly and splicing of the water outlet member 5 and the upper shell 1.

[0032] As shown in the attached Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 and Figure 8As shown, a telescopic tube 3 is provided between the upper shell 1 and the water outlet member 5. The two ends of the telescopic tube 3 are respectively connected to the top of the upper shell 1 and the water outlet member 5. Among them, the first end of the telescopic tube 3 passes through the top of the upper shell 1 and is connected to the water inlet member 4. Specifically, a connecting groove 11 is formed by the downward depression of the top of the upper shell 1. The inner wall of the connecting groove 11 is provided with internal threads, and a first through hole 12 penetrates through the bottom of the connecting groove 11. After the first end of the telescopic tube 3 passes through the first through hole 12, a connecting ring 31 is sleeved outside it. At this time, since the diameter of the connecting ring 31 is larger than the diameter of the first through hole 12 and smaller than the diameter of the connecting groove 11, when the connecting groove 11 is threadedly connected to the water inlet member 4, the connecting ring 31 will be pressed and fixed in the connecting groove 11, so that while the upper shell 1 is fixed on the water inlet member 4, the water inlet member 4 is communicated with the telescopic tube 3. In addition, the second end of the telescopic tube 3 is connected to the water outlet member 5. Specifically, a second through hole 27 penetrating into the connecting pipe 26 is provided at the bottom of the lower shell 2 connected to the water outlet member 5. After the second end of the telescopic tube 3 passes through the second through hole 27, a connecting ring 31 is sleeved outside it. At this time, since the diameter of the connecting ring 31 is larger than the diameter of the second through hole 27 and the inner diameter of the connecting pipe 26, when the connecting pipe 26 is threadedly connected to the water outlet member 5, the connecting ring 31 will be pressed and fixed between the connecting pipe 26 and the water outlet member 5, so that the water outlet member 5 is communicated with the telescopic tube 3. When in use, water flows from the water inlet member 4 through the telescopic tube 3 to the water outlet member 5. Among them, the water inlet member 4 can be a faucet or a water pipe, and the water outlet member 5 can be a faucet, a shower head or a water pipe.

[0033] It is worth mentioning that, as shown in the appendix Figure 7 and Figure 8 shown, the telescopic tube 3 is made of an elastic material, which is a flexible tube, and the telescopic tube 3 is bent in a spiral shape. Specifically, it can be a silicone tube, which has excellent resilience, small permanent deformation, and is harmless, non-toxic, odorless and environmentally friendly. In the spliced upper shell 1 and water outlet member 5, the telescopic tube 3 is stacked and stored in the accommodating space 14. While being neat and beautiful, the upper shell 1 can play a good protective effect on the telescopic tube 3, reducing the risks of aging, scratching, abrasion or breakage of the telescopic tube 3 during use, thereby extending the service life of the telescopic tube 3. And when the upper shell 1 and the water outlet member 5 are separated, after the telescopic tube 3 is stretched and used and needs to be stored again, the telescopic tube 3 can quickly elastically recover, facilitating the quick storage of the telescopic tube 3, and at the same time avoiding breakage of the telescopic tube 3 caused by excessive bending.

[0034] In addition, as shown in the appendix Figures 5 to 8As shown in the figure, waterproof washers 32 are sleeved on the outer sides of the connecting rings 31 at both ends of the telescopic tube 3. Specifically, a limiting groove 321 that is recessed inward is provided on the inner circumferential wall of the waterproof washer 32. When the waterproof washer 32 is sleeved on the outer side of the connecting ring 31, the side edge of the connecting ring 31 is embedded in the limiting groove 321. Among them, the waterproof washer 32 is made of an elastic material, specifically, it can be made of silicone material, which has excellent resilience and small permanent deformation. While ensuring that the waterproof washer 32 can be smoothly sleeved on the outer side of the connecting ring 31 for use, it can play an effective sealing role in the connection between the telescopic tube 3 and the water inlet part 4 and the water outlet part 5, preventing water leakage.

[0035] In addition, the upper shell 1 and the water outlet part 5 can also be detachably connected by threads. Specifically, internal threads are provided on the inner wall of the accommodating space 14 of the upper shell 1, and external threads are provided on the outer wall of the top of the water outlet part 5. Among them, the external threads are provided on the outer wall of the top of the lower shell 2 connected to the water outlet part 5. During assembly, by rotating the lower shell 2, the lower shell 2 is screwed onto the upper shell 1, so that the upper shell 1 and the water outlet part 5 can be quickly spliced and assembled together.

[0036] In summary, when the present utility model is in use, the upper shell 1 is fixed to the water inlet part 4, and both ends of the telescopic tube 3 are respectively connected to the water inlet part 4 and the water outlet part 5. At this time, water flows from the water inlet part 4 through the telescopic tube 3 to the water outlet part 5. As shown in the appendix Figure 8 As shown in the figure, when it is necessary to move the water outlet part 5 for use, such as flushing a pool, a floor or other objects, the water outlet part 5 can be removed from the bottom of the upper shell 1, and then the water outlet part 5 is moved for use. During the process, the telescopic tube 3 elastically deforms and stretches outward. By means of the detachable upper shell 1 and the water outlet part 5 cooperating with the telescopic telescopic tube 3, the present utility model enables the water outlet part 5 to turn and move the water at will, which is very convenient for users. In addition, as shown in the appendix Figure 1 and Figure 7 As shown in the figure, when the telescopic tube 3 does not need to be extended for use, the upper shell 1 and the water outlet part 5 can be spliced and assembled. At this time, the telescopic tube 3 is accommodated in the accommodating space 14 of the upper shell 1. While being tidy and beautiful, the upper shell 1 can play a good protective effect on the telescopic tube 3, reducing the risks of aging, scratching, abrasion or breakage of the telescopic tube 3 during use, thereby prolonging the service life of the telescopic tube 3.

[0037] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification made to the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
