[0029] Please refer to Figure 1 and Figure 4 The anti-loosening assembly 2 comprises a first threaded ring 201 threaded on the outer surface of the male joint 3, the outer surface of the first threaded ring 201 is hinged with a plurality of fixed rods 202, the fixed rods 202 are fixed with clamping rods 203 on the side close to the male joint 3, the anti-loosening assembly 2 further comprises a clamping ring 204 fixed on the outer surface of the female joint 1, the clamping ring 204 is provided with a clamping groove 205 on the side away from the male joint 3, and the clamping rods 203 are clamped with the clamping groove 205.

[0030] After the female connector 1 is connected to the male connector 3, the first threaded ring 201 is rotated to move towards the female connector 1, and then the fixing rod 202 is rotated towards the female connector 1. The fixing rod 202 can drive the snap-fit ​​rod 203 to rotate. When one side of the fixing rod 202 contacts one side of the snap-fit ​​ring 204, the snap-fit ​​rod 203 rotates to the side of the snap-fit ​​ring 204 away from the male connector 3 and then the first threaded ring 201 is rotated in the opposite direction. The first threaded ring 201 can drive the fixing rod 202 to move, and the fixing rod 202 can drive the snap-fit ​​rod 203 to move into the snap-fit ​​groove 205 of the snap-fit ​​ring 204 for snap-fit, thereby limiting the position of the first threaded ring 201 and the snap-fit ​​ring 204, thereby improving the stability of the connection between the female connector 1 and the male connector 3.

[0035] In use, the female connector 101 and the male connector 301 are inserted into each other. Simultaneously, the second sealing ring 7 is inserted into the interior of the first sealing ring 4. When one side of the threaded sleeve 5 contacts one side of the first sealing ring 4, the second threaded ring 6 on the threaded sleeve 5 is rotated. Rotating the second threaded ring 6 moves it to the outside of the first sealing ring 4 and the threaded sleeve 5, thus sealing the connection between the female connector 1 and the male connector 3. Then, the first threaded ring 201 is rotated and moved towards the female connector 1, and then rotated again towards the female connector 1. The fixing rod 202 can drive the snap-fit ​​rod 203 to rotate. When one side of the fixing rod 202 contacts one side of the snap-fit ​​ring 204, the snap-fit ​​rod 203 rotates to the side of the snap-fit ​​ring 204 away from the male connector 3 and then rotates the first threaded ring 201 in the opposite direction. The first threaded ring 201 can drive the fixing rod 202 to move. The fixing rod 202 can drive the snap-fit ​​rod 203 to move into the snap-fit ​​groove 205 of the snap-fit ​​ring 204 for snap-fit, thereby limiting the position of the first threaded ring 201 and the snap-fit ​​ring 204, thereby improving the stability of the connection between the female connector 1 and the male connector 3.
