[0022] Please refer to Figures 1-4 , the present invention provides a technical solution: a rotary joint convenient for assembly, including a fixed plate assembly 3. A limiting assembly 4 is evenly and fixedly connected to one side surface of the fixed plate assembly 3. The limiting assembly 4 includes a fixed shaft 41 and a limiting piece 42. The limiting piece 42 is rotatably connected to the circumferential surface of the fixed shaft 41. One side surface of the fixed plate assembly 3 is rotatably connected to a first connecting piece 1, and one end of the first connecting piece 1 is rotatably connected to a second connecting piece 2; the second connecting piece 2 includes a second connecting pipe 21 and a connecting plate 22, and the connecting plate 22 is fixedly connected to one end of the second connecting pipe 21. One side end of the circumferential surface of the second connecting pipe 21 is fixedly connected to a fixed pipe 23; one end surface of the fixed pipe 23 is fixedly connected to a flange 24, and a placing groove 242 is provided on one side surface of the flange 24. A sealing ring 25 is placed in the placing groove 242; a first fixing hole 241 is evenly penetrated through the edge of one side surface of the flange 24, and the total number of the first fixing holes 241 is four.

[0023] Working principle: When the conveniently assembled rotary joint needs to be assembled, only need to align the clamping block 12 on the first connecting piece 1 with the notch of the clamping groove 311, insert it into the clamping groove 311, and then rotate the fixed disk body 31 so that the clamping block 12 is no longer located at the notch of the clamping groove 311. Then rotate the limiting piece 42 to the notch of the clamping groove 311, and the first connecting piece 1 and the fixed disk assembly 3 can be quickly assembled. On the contrary, only need to rotate the limiting piece 42 so that it is not at the notch of the clamping groove 311, and then apply an outward pulling force to the first connecting piece 1, and the first connecting piece 1 and the fixed disk assembly 3 can be disassembled. The second connecting piece 2 and the first connecting piece 1 are designed as an integral rotation type, and by connecting the connecting pipe to one side of the flange 24, the connection in non-single and non-horizontal direction angles can be realized, which is relatively convenient and practical and is worthy of being vigorously promoted.

[0024] Among them, as Figure 3 shown, the first connecting piece 1 includes a first connecting pipe 11 and an annular groove 111, and the annular groove 111 is arranged at one end of the circumferential surface of the first connecting pipe 11. The other end of the circumferential surface of the first connecting pipe 11 is evenly and fixedly connected with clamping blocks 12; specifically, the clamping blocks 12 are used for clamping inside the clamping groove 311.

[0025] Among them, as Figure 3 shown, the fixed disk assembly 3 includes a fixed disk body 31 and a clamping groove 311, and the clamping groove 311 is arranged on one side surface of the fixed disk body 31. The edge of one side surface of the fixed disk body 31 is evenly and penetrated with second fixing holes 312; specifically, rotate the fixed disk body 31 so that the clamping block 12 is aligned with the notch on the clamping groove 311, and the first connecting piece 1 can be disassembled.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
