[0015] Please see Figure 1-4 This utility model provides a technical solution: a reinforced connection 304 stainless steel round tube water distributor, including a water distribution structure 1, a reinforced connection structure 2, a first connecting pipe 3 and a second connecting pipe 4. The lower end of the water distribution structure 1 is connected to the first connecting pipe 3, and the lower end of the first connecting pipe 3 is connected to the second connecting pipe 4. The water distribution structure 1 is also fixedly connected to the first connecting pipe 3 and the second connecting pipe 4 through the reinforced connection structure 2. Water distribution structure 1 is used for water distribution treatment. Water is distributed through the water distribution structure 1. Water flows into the water distribution circular pipe 5 through the conduit 6. The water is guided through the third connecting pipe 8 by the opening of the connecting valve 7. The reinforcement connection structure 2 is fastened to the third connecting pipe 8 by the first fastening screw bracket 11 on the first movable frame 10. At the same time, the second movable frame 14 is stretched by the spring frame 12 on the first movable frame 10. The second movable frame 14 is fastened to the first connecting pipe 3 to perform the stretching work. The second fastening screw bracket 15 is used to reinforce the connection. The third connecting pipe 8 is squeezed and pressed together with the first connecting pipe 3 and the second connecting pipe 4 by the spring frame 12 and the second movable frame 14. At the same time, the first connecting pipe 3 and the third connecting pipe 8 are threaded together to reinforce the connection and improve the connection stability. The reinforcement connection structure 2 is used for reinforcement connection. The second movable frame 14 performs elastic stretching of the first connecting pipe 3 and the second connecting pipe 4. The first movable frame 10 performs fastening connection with the third connecting pipe 8. The spring frame 12 has elastic stretching capacity, so that the first connecting pipe 3, the second connecting pipe 4 and the third connecting pipe 8 are squeezed and adhered.
[0016] The water distribution structure 1 includes a water distribution circular pipe 5, a conduit 6 connected to the water distribution circular pipe 5, and a connecting valve 7 connected to the connecting valve 7, which is connected to a third connecting pipe 8 to realize water distribution control.
[0017] The reinforcing connection structure 2 includes a first movable frame 10, which is hinged to a first hinge frame 9. The side end of the first movable frame 10 is fixed and screwed in place by a first fastening screw bracket 11, threading the first connecting pipe 3, the second connecting pipe 4, and the third connecting pipe 8 together. Then, the reinforcing connection structure 2 is installed by fitting the first movable frame 10 onto the third connecting pipe 8. The first movable frame 10 is then adjusted to rotate on the first hinge frame 9. The other end is threaded to the first fastening screw bracket 11, thus securing the first movable frame 10 to the third connecting pipe 8. At this point, the tension spring frame 1... 2. This allows the second movable frame 14 to be sleeved at the bottom of the first connecting pipe 3. Simultaneously, the second movable frame 14 rotates together with the first movable frame 10 via the spring frame 12, sleeved at the bottom of the first connecting pipe 3. Then, the second fastening screw frame 15 is screwed to fasten the second movable frame 14. The second movable frame 14 rotates on the second hinge frame 13. The second movable frame 14 rotates and adjusts together with the first movable frame 10, thereby stretching the second movable frame 14 via the spring frame 12. This allows the second movable frame 14 to efficiently fit the first connecting pipe 3, the second connecting pipe 4, and the third connecting pipe 8, improving the connection stability of the first connecting pipe 3, the second connecting pipe 4, and the third connecting pipe 8.
[0018] A spring frame 12 is fixedly connected to the first movable frame 10. A second movable frame 14 is telescopically connected to the lower end of the spring frame 12.

[0022] Working principle: When needed, the user threadedly connects the first connecting pipe 3, the second connecting pipe 4, and the third connecting pipe 8. Then, the reinforcing connection structure 2 is installed. The first movable frame 10 within the reinforcing connection structure 2 is fitted onto the third connecting pipe 8. The first movable frame 10 is then adjusted to rotate on the first hinge frame 9. The other end is threaded onto the first fastening screw frame 11, thus fastening the first movable frame 10 and fixing it to the third connecting pipe 8. At this time, the spring frame 12 is stretched, causing the second movable frame 14 to engage with the bottom of the first connecting pipe 3. The second movable frame 14 rotates together with the first movable frame 10 via the spring frame 12 and is fitted onto the bottom of the first connecting pipe 3. Then, the second fastening frame 15 is screwed on to fasten the second movable frame 14. The second movable frame 14 rotates on the second hinge frame 13 and rotates and adjusts together with the first movable frame 10. Thus, the second movable frame 14 is stretched by the spring frame 12, so that the second movable frame 14 can efficiently fit the first connecting pipe 3, the second connecting pipe 4 and the third connecting pipe 8, improve the connection stability of the first connecting pipe 3, the second connecting pipe 4 and the third connecting pipe 8, and complete the work.
