Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0022] In one embodiment of this utility model, such as Figures 1-4 As shown, a self-locking connector is provided, including a male connector 1 and a female connector 2. The male connector 1 is rotatably connected to a gripping part 11, and a connecting rod 12 extends from the gripping part 11 to one side. The end of the connecting rod 12 is provided with a buckle 121, and the buckle 121 is provided with a groove 13 on the side away from the gripping part 11. The surface of the female connector 2 is provided with an annular boss 21, and the annular boss 21 is recessed inward with a slot 20. The top of the slot 20 is open, and the slot 20 is provided with a mounting groove 201 on one side. The mounting groove 201 is provided with a spring piece 202 and a locking block 203. The locking block 203 slides in the mounting groove 201 toward or away from the male connector 1. A driving plate 204 is provided in the middle of the locking block 203. One side of the spring piece 202 abuts against the inner wall of the mounting groove 201, and the other side abuts against the driving plate 204. One end of the locking block 203 is engaged with the groove 13, and the other end is provided with a lever 205.

[0023] Furthermore, the buckle 121 has an arc surface on the side away from the gripping part 11, which is used to lift the locking block 203. Specifically, when the male seat 1 is inserted into the female seat 2, the connecting rod 12 pushes the buckle 121 into one end of the slot 20. Rotating the gripping part 11 causes the buckle 121 to slide into the slot 20, lifting the locking block 203 through the arc surface. This causes the paddle 205 to compress the spring 202 through the drive plate 204. When the buckle 121 slides to the corresponding position, the spring 202 pushes the locking block 203 into the groove 13, thus connecting the male seat 1 and the female seat 2 and reducing the installation steps.

[0024] Furthermore, a sliding groove 211 is coaxially provided within the annular boss 21, and an indicator ring 212 is slidably connected within the sliding groove 211. The indicator ring 212 is a non-closed annular structure, and a first indicator surface 213 and a second indicator surface 214 are respectively provided at both ends of the indicator ring 212. Specifically, when the male seat 1 is inserted into the female seat 2, the connecting rod 12 pushes the buckle 121 into one end of the slot 20. Rotating the gripping part 11 causes the buckle 121 to slide into the slot 20. During this process, the buckle 121 pushes the first indicator surface 213 into the sliding groove 211, while simultaneously sliding the second indicator surface 214 out of the sliding groove 211, thus achieving an indicator effect to determine whether the buckle 121 and the groove 13 are stably installed.

[0025] Furthermore, the male seat 1 is provided with a rotating groove 14, and the gripping part 11 rotates and engages within the rotating groove 14.

[0026] Furthermore, the slot 20 includes an insertion part 23 and a sliding part 24. The insertion part 23 opens towards the male seat 1, and the sliding part 24 is slidably connected to the buckle 121. Specifically, when the male seat 1 is inserted into the female seat 2, the connecting rod 12 pushes the buckle 121 into the insertion part 23, and rotating the gripping part 11 causes the buckle 121 to slide into the sliding part 24, thus achieving the connection effect.

[0027] Furthermore, the buckle 121 has a sloping surface on one side and an anti-slip pad on the other side, and the anti-slip pad abuts against the inner wall of the slot 20.

[0028] Working principle: When in use, insert the male connector 1 into the female connector 2. At this time, the connecting rod 12 pushes the buckle 121 into one end of the slot 20. Pull the lever 205 to move the locking block 203 away from the slot 20. At the same time, the lever 205 compresses the spring 202 through the drive plate 204. Then rotate the grip part 11 to make the buckle 121 slide into the slot 20. Then release the lever 205. The spring 202 pushes the drive plate 204 to slide closer to the buckle 121, thereby making the locking block 203 slide closer to the buckle 121. Finally, the locking block 203 is engaged in the groove 13, realizing the connection between the male connector 1 and the female connector 2.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
