[0002] Traditional drainage fittings are generally suitable for 50-caliber drainage pipes, and there is no way to achieve universal matching of 40, 50 and above drainage pipes. Drainage fittings cannot be installed during the renovation and relocation of old houses. Most traditional structural drainage fittings are parallel to our floor tile surfaces. When there is negative pressure in the drainage pipe, drainage is very slow or cannot be drained normally. Moreover, the rotating plate assembly of traditional drainage fittings is very difficult to install. When forcefully installed, the rotating plate assembly may break, and most drainage fittings cannot pass the relevant sealing standards. In this way, the odor in the pipe can easily enter the room and affect the living environment. Utility Model Content

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings, but the scope of protection of the present invention is not limited to the described scope.

[0031] like Figure 1 As shown, a drainage connection assembly suitable for various pipe diameters includes a lifting hook 1, an O-ring 2, a drainage member 3 and a rotating plate assembly 5, wherein the lifting hook 1 is provided on the upper portion of the drainage member 3, the O-ring 2 is installed on the outer surface of the drainage member 3, the rotating plate assembly 5 is arranged at the bottom of the drainage member 3, and a sealing gasket 4 is provided between the rotating plate assembly 5 and the drainage member 3.

[0032] like Figure 3 As shown, the drain component 3 includes a drain component body, and a socket 305 for connecting the drain pipe is provided at the bottom of the drain component body. The outer diameter of the socket 305 is less than 35 mm, which is smaller than the inner diameter of the 40 drain pipe, thereby realizing the universal use of various drain pipes such as 40, 50, 75, 90 or 110.

[0033] A connection port 302 is provided at the lower end of the socket 305, and the rotating plate assembly 5 is rotatably connected to the drain member 3. The lower surface of the socket 305 is inclined downward, and the angle between the lower end surface of the drain member 3 and the contact surface of the rotating plate assembly 5 is 5°~45°, preferably 10°, and the lower end surface of the connection port 302 is inclined downward.

[0034] The lower surface of the socket 305 and the lower end surface of the connecting port 302 of the utility model are inclined downward. When the drainage pipe is under negative pressure, the step surface can prevent the drainage member from not draining.

[0035] In this embodiment, connecting ears 313 are symmetrically provided on the outer surface of the connecting port 302 , and a first circular hole 310 and a second circular hole 311 are respectively formed on the two connecting ears 313 .

[0036] like Figure 7 As shown, the rotating plate assembly 5 includes a gravity block 504, a gravity groove is provided on the gravity block 504, and a light shielding platform 502 is provided on one side of the gravity groove. When viewed from the side, no light is transmitted, thereby achieving a sealing effect. The surface of the light shielding platform 502 facing the connection port 302 is a sealing surface 501, and the sealing gasket 4 of the sealing surface 501 can be tightly fitted to avoid gaps under the action of the gravity of the gravity block 504.

[0037] A space for accommodating the gravity block 504 is provided between the two connecting ears 313 , and the two connecting ears are rotatably connected to the rotating plate assembly 5 via the rotating shaft 503 passing through the first circular hole 310 and the second circular hole 311 .

When installing the rotating plate assembly 5, the rotating shaft 503 on the rotating plate assembly 5 is first placed inside the first circular hole 310 and the second circular hole 311, and then the other side of the rotating shaft 503 is installed from one side of the guide groove 303. This structure can easily install the rotating plate assembly 5 on the drainage component 3 to avoid the rotating shaft 503 from breaking due to force. The installation is fast and convenient with high efficiency.

[0039] like Figure 3 As shown, when the rotating plate assembly 5 rotates more than 90 degrees, it may get stuck or the rotating plate assembly 5 cannot return to its original position due to gravity, resulting in a loss of sealing effect, causing the odor in the drain pipe to enter the room. Therefore, a return platform 304 is provided between the outer surface of the connecting port 302 facing the connecting ear 313 and the socket 305. The outer surface of the return platform 304 is an inclined surface, so that the rotating plate assembly can only move within a range of less than 90 degrees without getting stuck.

In this embodiment, the sealing gasket 4 is an irregular sealing gasket.

[0041] like Figure 4 As shown, the upper end surface of the drainage member body is symmetrically provided with a first boss 308 for clamping the filter screen, referring to Figure 8 The filter screen can be placed on a pair of first bosses 308, so that the filter screen will not float up when the drainage member 3 drains water, thereby avoiding affecting the drainage effect.

[0042] A third boss 306 is disposed between two adjacent first bosses 308 . A mounting hole 307 is formed on each third boss 306 . Two ends of the lifting hook 1 are mounted in the mounting holes 307 .

[0043] like Fig. 9 As shown, in this embodiment, both ends of the lifting hook 1 are connection ends 101 , and the connection ends 101 on the lifting hook 1 are installed inside the installation hole 307 to achieve the purpose of connecting with the drainage member 3 .

[0044] like Figure 5 As shown, an outer groove 312 is provided on the outer surface of the drainage member body, and an O-ring 2 is installed in the outer groove 312 to play a sealing role.
