[0024] See also Figure 1-3 The utility model provides a technical solution: a pipe joint structure for preventing a pipe fitting and a pipe joint from loosening, comprising a pipe 10, and further comprising:

[0025] A connecting sleeve 11, a pair of pipes 10 are respectively installed at both ends of the connecting sleeve 11; the outer sides of the pair of pipes 10 are provided with external threads, and the inner wall of the connecting sleeve 11 is provided with internal threads adapted thereto, and the connection between the connecting sleeve 11 and the pipes 10 can be realized by screwing the pipes 10 into the connecting sleeve 11;

[0026] The limiting mechanism includes an embedding strip 12, a first retaining ring 13 and a second retaining ring 14. The embedding strip 12 is hinged on the connecting sleeve 11. The first retaining ring 13 is installed on the outside of the pipe 10. The second retaining ring 14 is installed on the end of the connecting sleeve 11. There is a locking position in the rotation stroke of the embedding strip 12. In the locking position, the embedding strip 12 is simultaneously clamped in the first retaining ring 13 and the second retaining ring 14. By installing the second retaining ring 14 on the end of the connecting sleeve 11 and adding the first retaining ring 13 on the outside of the pipe 10, the first retaining ring 13 and the second retaining ring 14 fit each other and are turned over by the embedding strip 12. The first retaining ring 13 and the second retaining ring 14 are provided with a position avoidance opening adapted to the embedding strip 12. By embedding the embedding strip 12, the mutual rotation between the first retaining ring 13 and the second retaining ring 14 can be limited, so that the first retaining ring 13 and the second retaining ring 14 are fixed, so that the position limitation between the pipe 10 and the connecting sleeve 11 can be achieved. The installation stability between the pipe 10 and the connecting sleeve 11 is ensured, and the pipe 10 or the connecting sleeve 11 can be rotated by simply flipping the embedding strip 12 to disengage it from the first retaining ring 13 and the second retaining ring 14, so as to realize the disassembly between the pipe 10 and the connecting sleeve 11, which is convenient for installation.

[0027] The safety component includes a collar 15, which is slidably sleeved on the outside of the plurality of embedding strips 12. The collar 15 can be set to limit the embedding strips 12 to prevent the embedding strips 12 from being separated from the first retaining ring 13 and the second retaining ring 14 during use, so that the embedding strips 12 can only be firmly embedded in the first retaining ring 13 and the second retaining ring 14.

[0028] It also includes a sliding rod 16, a mounting sleeve 17 and an elastic member 18. The mounting sleeve 17 is fixedly mounted on the outside of the connecting sleeve 11. One end of the sliding rod 16 is mounted on the collar 15. The other end of the sliding rod 16 is slidably inserted into the inside of the mounting sleeve 17. The elastic member 18 is arranged in the mounting sleeve 17. Through the elastic force of the elastic member 18, the sliding rod 16 has a tendency to move axially toward the pipe 10. The sliding rod 16 slides to drive the collar 15 to be sleeved on the outside of the embedding strip 12, so as to prevent the embedding strip 12 from unfolding.

[0029] The installation sleeve 17 is provided with a cavity, and the elastic member 18 is installed in the cavity. One end of the sliding rod 16 penetrates into the cavity, and one end of the elastic member 18 abuts against the end of the sliding rod 16. When disassembling, the elastic member 18 is compressed by pressing the collar 15, and the collar 15 is close to the installation sleeve 17, and the collar 15 will be separated from the embedding strip 12. In this way, without the restriction of the collar 15, the embedding strip 12 can be smoothly turned over.

[0030] The first retaining ring 13 and the second retaining ring 14 are both provided with a rubber coating on one side where they are in contact with each other, and the thickness of the rubber coating is not less than 3 mm. The rubber coating can improve the sealing performance, and due to the deformable characteristics of the rubber coating, the final stop position can be ensured when the pipe 10 and the connecting sleeve 11 rotate relative to each other, and the avoidance openings on the first retaining ring 13 and the second retaining ring 14 can be in contact with each other to ensure that the embedding strip 12 is smoothly embedded in the first retaining ring 13 and the second retaining ring 14.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
