[0018] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0019] Reference Figure 1-Figure 5 As shown, a rotary buckle includes a male buckle body 1, a female buckle body 2, a locking device 3, and a releasing device 4. The male buckle body 1 is provided with a rotating shaft 11, and the end of the rotating shaft 11 is provided with an anti-falling block 111. The female buckle body 2 is provided with a mounting groove 21. The front end of the male buckle body 1 is installed in the mounting groove 21, and the middle part of the mounting groove 21 is provided with a rotating hole 22 adapted to the rotating shaft 11. A through hole 23 is provided next to the rotating hole 22 for the anti-falling block 111 to pass through. Specifically, the rotating shaft 11 is inserted into the rotating hole 22 to connect the male buckle body 1 and the female buckle body 2. At the same time, the male buckle body 1 is rotated to make the anti-falling block 111 move away from the The through hole 23 is stuck on the back side of the female buckle body 2, thereby preventing the rotating shaft 11 from disengaging from the rotating hole 22, and further preventing the male buckle body 1 from slipping off the female buckle body 2, thereby improving the stability and firmness of the connection between the male buckle body 1 and the female buckle body 2. The locking device 3 is arranged between the male buckle body 1 and the female buckle body 2 to relatively fix the male buckle body 1 and the female buckle body 2, further ensuring that the male buckle body 1 will not accidentally slip off. The unlocking device 4 is arranged on the female buckle body 2 to unlock the locking device 3, so that the anti-slip block 111 can be rotated to the position of the through hole 23, thereby allowing the male buckle body 1 and the female buckle body 2 to be separated.

[0020] The front end of the male buckle body 1 is provided with an arc-shaped surface 12 .

[0021] The locking device 3 includes a locking cavity 31, a locking spring 32, a locking slot 33, and a locking post 34. The locking cavity 31 is provided on the female buckle body 2, the locking spring 32 is provided in the locking cavity 31, the locking slot 33 is provided at the front end of the male buckle body 1, and the locking post 34 is provided in the locking cavity 31. One end of the locking post 34 is connected to the locking spring 32, and the other end of the locking post 34 extends out of the locking cavity 31 and is locked in the locking slot 33. The end of the locking post 34 is provided with an inverted tapered structure 341, and a guide curved surface 331 is provided at the entrance position of the locking slot 33. The inverted tapered structure 341 and the guide curved surface 331 are used to make it easier for the end of the locking post 34 to enter the locking slot 33. Specifically, after the anti-dropping block 111 passes through the through hole 23 , the male buckle body 1 rotates 90° around the rotation hole 22 so that the locking post 34 is locked into the locking groove 33 .

[0022] The unlocking device 4 includes a movable groove 41 and a movable block 42. The movable groove 41 is provided on the female buckle body 2 and communicates with the locking cavity 31. The movable block 42 is disposed within the movable groove 41 and is connected to the locking post 34 to drive the locking post 34 into the locking cavity 31. Specifically, the movable block 42 is connected and fixed to the locking post 34 via bolts. The top of the movable block 42 is provided with anti-slip ridges 421, which are used to increase friction between the finger and the movable block 42. When in use, press the moving block 42 and move it toward the tail end of the female buckle body 2. At this time, the locking column 34 will move with the moving block 42, thereby retracting into the locking cavity 31, so that the male buckle body 1 can be rotated relative to the female buckle body 2, so that the anti-slip block 111 can be rotated to the bottom of the through hole 23, thereby allowing the male buckle body 1 and the female buckle body 2 to be separated.

[0023] The above are only some specific implementation methods of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
