[0019] The working principle of the stainless steel pipe which is easy to disassemble and assemble is realized by the cooperation of the main pipe body 1, the auxiliary pipe body 2, the mounting ring 3, the main sleeve ring 4 and the auxiliary sleeve ring 5. Figures 1 to 5 As shown, first the staff puts the mounting ring 3 on the auxiliary tube body 2, and then puts the auxiliary sleeve 5 on the auxiliary tube body 2, and then moves the mounting ring 3 and the auxiliary sleeve 5 along the auxiliary tube body 2 to the position of the connecting flange 6, rotates the auxiliary sleeve 5 and makes the auxiliary sleeve 5 threadedly connected with the main sleeve 4 of the main tube body 1, and in the process of connecting the main sleeve 4 and the auxiliary sleeve 5, the auxiliary sleeve 5 drives the mounting ring 3 to move along the auxiliary tube body 2 and makes the plug 8 on the mounting ring 3 inserted into the mounting through hole 7 of the connecting flange 6 of the main tube body 1 and the auxiliary tube body 2. After the main sleeve 4 and the auxiliary sleeve 5 are connected, the main sleeve 4 and the auxiliary sleeve 5 cooperate to abut against the two connecting flanges 6, thereby completing the connection between the main tube body 1 and the auxiliary tube body 2. Compared with traditional stainless steel pipes, this stainless steel pipe that is easy to disassemble and assemble does not require the operation of tightening bolts multiple times, simplifies the operating steps in the installation process, is easy to operate and easy to install and use.

[0020] Specifically, the main sleeve 4 is a concave ring body, and the inner side of the main sleeve 4 is provided with an internal thread, the secondary sleeve 5 is provided with a mounting protrusion 9, the mounting protrusion 9 is provided with an accommodating cavity 10, and the outer side of the mounting protrusion 9 is provided with an external thread, and the external thread of the mounting protrusion 9 is threadedly connected to the internal thread of the main sleeve 4, wherein a plurality of the mounting through holes 7 are uniformly arranged on the connecting flange 6, and a plurality of the plug posts 8 are uniformly arranged on one side of the mounting ring 3, and the length of the plug posts 8 is less than the sum of the lengths of the mounting through holes 7 of the two connecting flanges 6, as shown in FIG. Figures 1 to 5 As shown, when the secondary ring 5 is connected to the main ring 4, the external thread of the mounting protrusion 9 of the secondary ring 5 is threadedly connected to the internal thread of the main ring 4, the mounting protrusion 9 gradually extends into the main ring 4, and the accommodating cavity 10 of the mounting protrusion 9 can accommodate the mounting ring 3 and two connecting flanges 6, and the plug column 8 of the mounting ring 3 is inserted into the mounting through hole 7 of the two connecting flanges 6.

[0021] Furthermore, a guide groove 11 is provided on the outer side of the secondary tube body 2, a guide block 12 is provided on the inner side of the mounting ring 3, and the guide block 12 of the mounting ring 3 is slidably connected to the guide groove 11.
