[0024] Embodiment 1:

[0025] Please refer to Figures 1 to 5 As shown, a sealed round-to-square water outlet elbow 100 for wall outlet includes: a round-to-square adapter 2, which consists of a circular interface connected to the in-wall drain pipe 200 and a square interface connected to the water outlet square pipe. The circular interface and the square interface are perpendicularly arranged, and the inner diameter of the circular interface is larger than the outer diameter of the in-wall drain pipe 200; a lining seal 1, which is arranged between the circular interface of the round-to-square adapter 2 and the in-wall drain pipe 200. Its outer diameter matches the circular interface of the round-to-square adapter 2, and its inner diameter matches the outer diameter of the in-wall drain pipe 200. The lining seal 1 is connected to the in-wall drain pipe 200, and at least one sealing structure 6 is also provided on the surface of the lining seal 1 that contacts the outer wall of the in-wall drain pipe 200; a square pipe socket 3, which is connected to the square interface of the round-to-square adapter 2 and is used to connect the falling water square pipe 300.

[0026] Preferably, the sealing structure 4 includes a sealing groove 61 and a sealing ring 62, and the sealing ring 62 is installed in the sealing groove 61. The sealing ring is mainly used to prevent liquid from leaking around the pipe and leaking from the connection port.

[0027] Preferably, the lining seal 1 is made of metal.

[0028] Preferably, the round-to-square adapter 2 is made of metal.

[0029] Preferably, the round-to-square adapter 2 and the lining seal 1 are fixedly connected by welding or threading.

[0030] Preferably, threaded holes 5 are also opened at the top of the round-to-square adapter 2 and the lining seal 1 near the circular interface, and the round-to-square adapter 2 and the lining seal 1 are fixedly connected to the in-wall drain pipe 200 by screwing with screws through threads.

[0031] Preferably, the round-to-square adapter 2 and the lining seal 1 can also be connected by riveting.

[0032] Preferably, the lining seal 1 is provided with two parallel sealing grooves 61 and sealing rings 62 (as Figure 4 or Figure 5As shown in the figure, two sealing rings can strengthen the sealing effect on the water pipe, further ensuring the sealing performance of the pipe. At the same time, it also prevents problems with the first sealing ring. The second sealing ring can also play a backup strengthening role.

[0033] Preferably, an inclined surface is formed along the circumferential direction of the inner diameter edge of the inner lining seal 1 (as Figure 5 shown in the figure), so that the inner drain pipe 200 can be smoothly inserted and connected.

[0034] The working principle of the present utility model is as follows:

[0035] First, machine-process the inner lining seal 1 so that its outer diameter can be inserted into the inner diameter of the circular interface of the customized round-to-square adapter 2. Machine-process the inner circle to match the outer diameter of the inner drain pipe 200. Then machine-process the inclined mouth of the inner diameter edge so that the inner drain pipe 200 can be smoothly inserted and connected. Then machine-process the sealing groove. The sealing ring 6 is mainly used to prevent liquid from leaking around the pipe and leaking from the connection port. If multiple sealing grooves are processed, multiple sealing rings 6 can strengthen the sealing effect on the water pipe, further ensuring the sealing performance of the pipe. At the same time, it also prevents problems with the first sealing ring 6. The second sealing ring can also play a backup strengthening role. A threaded hole 5 is opened on one side of the top of the round-to-square adapter 2 close to the circular interface. The round-to-square water outlet elbow 100 is connected and fixed to the inner drain pipe 200 by threaded connection, thereby preventing a large amount of water from flowing out of the water outlet and causing the round-to-square water outlet elbow 100 to separate from the inner drain pipe 200.

[0036] The square interface of the round-to-square adapter 2 is connected to the square pipe socket 3, and the square pipe socket 3 is used to connect the downspout square pipe.

[0037] Although the specific implementation manners of the present utility model have been described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the present utility model. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present utility model should be covered within the scope protected by the claims of the present utility model.
