The outer connecting ring 14 is integrally formed on the outer wall of the front end of the male head main body 11. The wedge-shaped locking groove 16 is opened on the outer wall of the outer connecting ring 14. The elastic pin member 17 is movably inserted into the inside of the outer connecting ring 14.

[0025] The female connecting head 2 includes a female head main body 21, a rotary connecting ring 24, a sealing rubber sleeve 25 and a sealing lock block 26. The rotary connecting ring 24 is rotatably connected to the outer surface of the female head main body 21. The sealing rubber sleeve 25 is movably arranged inside the female head main body 21, and the sealing rubber sleeve 25 abuts against the inner wall of the male connecting head 1. The sealing lock block 26 is integrally formed on the inner wall of the rotary connecting ring 24.

[0026] The rotary connecting ring 24 is movably sleeved on the outer wall of the male head main body 11. The sealing lock block 26 is movably inserted into the inside of the wedge-shaped locking groove 16. The elastic pin member 17 is movably clamped with the sealing lock block 26. A slot 15 is opened on the outer wall of the outer connecting ring 14. The end of the slot 15 is communicated with the wedge-shaped locking groove 16. The sealing lock block 26 is movably inserted into the inside of the wedge-shaped locking groove 16 through the slot 15.

[0027] Insert the male head main body 11 into the rotary connecting ring 24 on the outer surface of the female head main body 21, and make the rod-shaped conductor 12 inserted into the socket 22. At this time, rotate the rotary connecting ring 24 so that the sealing lock block 26 faces the slot 15, then further push the male head main body 11 inward, and then rotate the rotary connecting ring 24 so that the sealing lock block 26 enters the wedge-shaped locking groove 16. Use the wedge-shaped locking groove 16 to relatively pull the male head main body 11 and the female head main body 21 closer, so that the sealing rubber sleeve 25 is squeezed to improve the sealing performance.

[0028] More specifically, a rod-shaped conductor 12 is fixedly arranged inside the male head main body 11, a socket 22 is fixedly arranged inside the female head main body 21, and the rod-shaped conductor 12 is movably inserted into the inside of the socket 22.

[0029] More specifically, an annular docking portion 13 is integrally formed on the outer wall of the rod-shaped conductor 12, a sealing assembly portion 23 is integrally formed on the outer wall of the socket 22. The sealing rubber sleeve 25 is movably sleeved on the outer surface of the sealing assembly portion 23. The sealing rubber sleeve 25 is in close contact with the inner wall of the outer connecting ring 14. The end of the sealing rubber sleeve 25 abuts against the annular docking portion 13, so as to increase the length of the sealing area and ensure the reliability of the sealing.

[0030] More specifically, the elastic latch member 17 includes a sliding ring 171 and a plug rod 172. The sliding ring 171 is slidably connected to the outer surface of the male head body 11. One end of the plug rod 172 is fixedly connected to the sliding ring 171. The other end of the plug rod 172 extends into the wedge-shaped locking groove 16, and the plug rod 172 is movably inserted into the inside of the sealing lock block 26. A spring 174 is movably sleeved on the outer surface of the plug rod 172 near the sliding ring 171. A retaining ring 173 is fixedly sleeved on the outer surface of the plug rod 172 far from the sliding ring 171. Both the retaining ring 173 and the spring 174 are slidably connected to the inner side wall of the outer connecting ring 14. By pushing the sliding ring 171 outward, the plug rod 172 is removed from the wedge-shaped locking groove 16. Then, the rotary connecting ring 24 is rotated so that the sealing lock block 26 enters the wedge-shaped locking groove 16. The sliding ring 171 is released, so that the plug rod 172 is inserted into the sealing lock block 26 to perform rotary locking on the rotary connecting ring 24, avoiding self-rotation during use and causing opening, and replacing the traditional threaded connection structure to avoid jamming caused by rust.
