[0037] The nut assembly 2 of the main flush joint of the toilet of the utility model sets the washer 23 between the installation nut 21 and the locking nut 22. When not locked, the washer is in an unpressed state, and the connecting pipe 3 can be easily plugged with the joint body 1. When the connecting pipe 3 is plugged in place, the locking nut 22 locks the installation nut 21. During the locking process, the locking nut 22 squeezes the washer 23, so that the circumference of the washer 23 is evenly pressed against the outer ring of the connecting pipe 3, thereby driving the inner ring of the connecting pipe 3 to be evenly locked to the joint body 1, and realizing the sealing and locking of the connecting pipe 3. The utility model can realize the effective sealing and locking of the connecting pipe 3 by only adding two parts, the washer 23 and the locking nut 22, and has a simple structure, convenient operation, and reliable function.

[0038] like Figure 1 As shown, in this embodiment, the joint body 1 is a T-shaped structure having a joint cap 11 and a connecting section 12. The connecting section 12 is provided with a first external thread 13 for threading a mounting nut 21, and the mounting nut 21 is detachably locked on the joint body 1. A ceramic piece 14 is provided between the mounting nut 21 and the joint cap 11, and a sealing ring 15 is provided between the ceramic piece 14 and the joint cap 11.

When the connecting pipe 3 is installed, its top end abuts against the connecting wall 215, and the inner diameter of the connecting wall 215 is smaller than the inner diameter of the inner cavity wall 213, which is convenient for the installation of the gasket 23.

[0040] like Figure 4 and Figure 5 As shown, the end of the locking nut 22 connected to the mounting nut 21 is provided with a second external thread 221 corresponding to the second internal thread 214 of the mounting nut 21, and the inner circumference top of the locking nut 22 is provided with a locking bevel 222. In this embodiment, the locking bevel 222 is formed by the inner circumferential wall of the locking nut 22 gradually expanding outward toward the top end, so as to squeeze the washer 23. In this embodiment, a neck 223 is formed at the end of the locking nut 22 connected to the mounting nut 21, and the second external thread 221 is arranged at the outer circumference of the neck 223. By providing the neck 223, when the mounting nut 21 and the locking nut 22 are screwed together, the mounting nut 21 is flush with the outer circumference of the locking nut.

[0041] The washer 23 may be a triangular washer, which is installed in the installation cavity 212 of the installation nut 21, and the top of the washer 23 is against the inner cavity wall 213 of the installation nut 21, and the bottom of the washer 23 faces the locking nut 22. The bottom of the washer 23 is provided with a pressure inclined surface 231 corresponding to the locking inclined surface 222 of the locking nut 22. In this embodiment, the pressure inclined surface 231 is formed by the bottom of the washer 23 gradually expanding upward and outward. When the locking nut 22 is tightened to the installation nut 21, the locking inclined surface 222 of the locking nut 22 will push the pressure inclined surface 231 of the washer 23 outward, so that the washer 23 presses the connecting pipe 3 inward.

[0042] like Figures 7 to 10 As shown, when the main flush joint of the toilet of the utility model is installed, the washer 23 is installed into the installation cavity 212 of the installation nut 21, and the locking nut 22 is screwed on the installation nut 21 (not completely locked, and the washer is not squeezed) to form a nut assembly 2, and the ceramic part 14 is sealed and fixed to one end of the joint cap 11 of the joint body 1 through the sealing ring 15, so that the joint body 1 and the nut assembly form two parts; then the connecting section 12 of the joint body 1 is inserted into the nut assembly 2, and the two parts are fixedly connected together through the first external thread 13 of the joint body 1 and the first internal thread 211 of the installation nut 21.
