In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0036] like Figures 1 to 8As shown, the utility model discloses a disassembly, locking and fixing structure 10 for a water discharger and a water discharge pipe, which comprises a water discharge upper cover 1, a water discharge main body 2, a locking nut 3 and a sealing ring 4. The water discharge upper cover 1 is detachably connected to one end of the water discharge main body 2, the other end of the water discharge main body 2 is arranged in the locking nut 3, and the bottom end of the water discharge main body 2 protrudes to the bottom end of the locking nut 3, the locking nut 3 is arranged on the outer periphery of the water discharge main body 2, the sealing ring 4 is arranged on the outer periphery of the water discharge main body 2, the sealing ring 4 is connected to the bottom end of the locking nut 3, and the inner ring of the sealing ring 4 facing the water discharge main body 2 and the outer periphery of the water discharge main body 2 are provided with convex ribs and grooves that cooperate with each other.

[0037] The utility model sets a locking nut 3 connected with a sealing ring 4 on the water discharge main body 2. When in the initial position, the sealing ring 4 is in a matching state with the convex rib and the groove set on the water discharge main body 2, that is, the convex rib is located in the groove, so that the water discharge main body 2 can be easily avoided and installed in the water discharge pipe 20; when the water discharge main body 2 is inserted into the water discharge pipe 20, the locking nut 3 is rotated to drive the sealing ring 4 connected with the locking nut 3 to move upward or downward with the locking nut 3, and generate relative movement with the water discharge main body 2, so that the sealing ring 4 and the convex rib and the groove set on the water discharge main body 2 are misaligned, and then the outer wall of the water discharge main body 2 squeezes the sealing ring 4, so that the outer wall of the sealing ring 4 and the inner wall of the water discharge pipe 20 form an interference lock. The utility model can realize the bidirectional locking of the water discharge pipe and the water discharge device by adding a locking nut connected with the sealing ring 4, and the structure is simple.

[0038] In this embodiment, the inner ring of the sealing ring 4 is provided with a convex rib 41, and the outer periphery of the water discharge body 2 is provided with a groove 21 that matches the convex rib 41 of the sealing ring 4. After the locking nut 3 is installed on the water discharge body 2, the convex rib 41 of the sealing ring 4 below the locking nut 3 is located in the groove 21 of the water discharge body 2, and a minimum spacing is formed between the water discharge body 2 and the sealing ring 4, which facilitates the installation of the water discharge pipe 20. Preferably, the upper and lower end surfaces of the convex rib 41 and / or the upper and lower end surfaces of the groove 21 are provided with transition surfaces, which can be inclined surfaces or curved surfaces. Figures 1 to 11 The upper and lower end surfaces of the rib 41 and the groove 21 shown in the figure are both provided with transition slopes 42 and 26.

[0039] like Figure 3 and Figure 4 As shown, the water launch body 2 is a T-shaped structure having an upper section 2A and a lower section 2B. The upper section 2A is connected to the water launch cover 1 to cooperate with Figure 1In the present embodiment, the water launching upper cover 1 and the water launching main body 2 are connected together by means of a screw buckle. Specifically, at least two screw corners 11 are arranged at equal intervals on the outer periphery of the water launching upper cover 1, and a screw groove 22 corresponding to the screw corners 11 is arranged on the outer periphery of the upper section 2A of the water launching main body 2. The screw groove 22 has an opening 23 for the screw corner 11 to be inserted into and a stop edge 24 opposite to the opening 23. When the water launching upper cover 1 and the water launching main body 2 are connected, it is only necessary to insert the screw corner 11 of the water launching upper cover 1 from the opening of the upper section 2A of the water launching main body 2 until it contacts the stop edge 24, thereby completing the installation of the water launching upper cover 1 and the water launching main body 2. When disassembling, it is only necessary to rotate the water launching upper cover 1 in the opposite direction to make the screw corner 11 fall out of the opening 23. In order to avoid accidental disassembly, a limiting mechanism can be further provided between the buckle angle 11 and the buckle groove 22, such as mutually matching convex particles and concave particles. When the water discharge cover 1 is installed to abut against the stop edge 24, the convex particles are inserted into the concave particles. When disassembling, a little force is required to make the convex particles disengage from the concave particles, and then the buckle angle 11 is taken out from the opening 23, so as to facilitate the cleaning of the water discharge cover 1. The outer periphery of the top end of the lower section 2B of the water discharge main body 2 is provided with an external thread 25, and the outer periphery of the bottom end of the lower section 2B of the water discharge main body 2 is provided with the concave particles 21.

[0040] like Figures 5 to 8 As shown, the inner ring of the top end of the locking nut 3 is provided with an internal thread 31 corresponding to the external thread 25 of the water discharge body 2. The height of the locking nut 3 is less than the height of the lower section 2B of the water discharge body 2. The bottom end of the locking nut 3 is connected to the sealing ring 4 by means of a hook and a slot. In this embodiment, the outer periphery of the bottom end of the locking nut 3 is inwardly contracted to form an installation area 32, and the installation area 32 is concave to form a slot 33. The upper part of the sealing ring 4 is installed on the installation area 32 of the locking nut 3. The sealing ring 4 is provided with a hook 43 protruding into the slot 33. After the hook 43 of the sealing ring 4 cooperates with the slot 33, the outer periphery of the sealing ring 4 is flush with the outer periphery of the locking nut 3 through the setting of the installation area 32, which is convenient for the installation of the water discharge pipe 20.

[0041] like Fig. 9 As shown, when unlocked, the hook 43 of the sealing ring 4 is installed in the groove 33 of the locking nut 3, and the rib 41 of the sealing ring 4 is located in the groove 21 of the water discharge body 2. At this time, the sealing ring 4 has a clearance fit with the water discharge body 2 and the clearance fit with the water discharge pipe 20, and can be smoothly extended into the water discharge pipe 20.

[0042] like Fig.10 As shown, in the first locking state, the locking nut 3 is screwed down or the water discharge body 2 is screwed up so that the locking nut 3 and the sealing ring 4 move downward relative to the water discharge body 2, and the transition slope 26 at the lower end of the groove 21 of the water discharge body 2 presses against the transition slope 42 at the lower end of the rib 41 of the sealing ring 4, so that the sealing ring 4 is deformed outward, thereby realizing the interference sealing locking fit between the sealing ring 4 and the inner wall of the water discharge pipe 20 and between the sealing ring 4 and the water discharge body 2.

[0043] like Fig.11 As shown, in the second locking state, the locking nut 3 is screwed up or the water discharge body 2 is screwed down so that the locking nut 3 and the sealing ring 4 move upward relative to the water discharge body 2, and the transition slope 26 at the upper end of the groove 21 of the water discharge body 2 presses against the upper end transition slope 42 of the rib 41 of the sealing ring 4, so that the sealing ring 4 is deformed outward, thereby realizing the interference sealing locking fit between the sealing ring 4 and the inner wall of the water discharge pipe 20 and the sealing ring 4 and the water discharge body 2.

[0044] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
