[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a safety buckle with a safety structure includes a fixed buckle 1. One end of the fixed buckle 1 is rotatably installed with a rotating buckle 2. The top end of the rotating buckle 2 in the reset state abuts against the other end of the fixed buckle 1 to prevent the rotating buckle 2 from rotating excessively during reset; an insurance mechanism is arranged inside the rotating buckle 2, and the insurance mechanism is used to prevent the rotating buckle 2 from being opened in a non-artificial operation state; a connecting handle 10 is arranged outside the fixed buckle 1 and penetrates into the fixed buckle 1 and is connected to the insurance mechanism.

[0021] In this embodiment: First, when connecting the safety rope to the safety buckle, first press down the connection handle 10. The connection handle 10 drives the insurance mechanism to open. Then, by applying an inward pressing force to the rotating buckle 2, the inward pressing force pushes the rotating buckle 2 to rotate inward. At this time, the top of the rotating buckle 2 is misaligned with one end of the fixed buckle 1. Then, the safety rope can be inserted into the safety buckle from the misaligned position between the rotating buckle 2 and the fixed buckle 1. The force applied to the connection handle 10 is maintained during the above process. After the safety rope is inserted, the pressing force applied to the rotating buckle 2 is removed. When the rotating buckle 2 is fully reset, the downward pressure applied to the connection handle 10 is removed. At this time, the insurance mechanism resets and closes, and the reset insurance mechanism locks the rotating buckle 2 in the current position. When the rotating buckle 2 is subjected to an inward pressing force, the rotating buckle 2 cannot rotate inward.

[0022] Please refer specifically to Figure 2 , a rotating shaft 3 is provided at the rotating connection between the fixed buckle 1 and the rotating buckle 2. The rotating shaft 3 is fixedly connected to the fixed buckle 1, and the rotating buckle 2 is rotatably connected to the rotating shaft 3. A torsion spring 5 is sleeved outside the rotating shaft 3. One end of the torsion spring 5 is engaged with the rotating buckle 2, and the other end of the torsion spring 5 is engaged with the fixed buckle 1. Engagement grooves for engaging the ends of the torsion spring 5 are provided at the contact positions of the fixed buckle 1, the rotating buckle 2 and the ends of the torsion spring 5.

[0023] In this embodiment: When the rotating buckle 2 rotates inward, one end of the torsion spring 5 engaged with the rotating buckle 2 is twisted, while the end of the torsion spring 5 engaged with the fixed buckle 1 remains stationary. At this time, the torsion spring 5 is twisted. When the pressing force applied to the rotating buckle 2 is removed, the torsion spring 5 resets at this time, driving the rotating buckle 2 to reset.

[0024] Please refer specifically to Figure 3 , the insurance mechanism includes a receiving groove 6 opened inside the rotating buckle 2. A spring 7 is connected to the bottom end of the inner wall of the receiving groove 6. A connecting plate 8 is slidably connected to the inner wall of the receiving groove 6. The bottom end of the connecting plate 8 is fixedly connected to the top of the spring 7. An insurance pin 9 integrally formed at the top of the connecting plate 8 penetrates into the fixed buckle 1.

[0025] In this embodiment: When opening the insurance mechanism, by applying a downward pressing force to the connection handle 10, the connection handle 10 drives the connecting plate 8 to slide downward along the inner wall of the receiving groove 6. The downward sliding connecting plate 8 squeezes the spring 7, and the spring 7 is compressed until the connecting plate 8 drives the insurance pin 9 to be completely separated from the fixed buckle 1;

[0026] After the safety rope is inserted, the force applied to the connection handle 10 is removed. At this time, the spring 7 resets, the spring 7 pushes the connecting plate 8 to reset, and the connecting plate 8 drives the insurance pin 9 to be inserted into the fixed buckle 1 again, completing the closing of the insurance mechanism.

[0027] Please refer specifically toFigure 3 Both the inside of the fixed buckle 1 and the rotating buckle 2 are provided with circular grooves for the safety pin 9 to slide up and down.

[0028] In this embodiment: The circular groove provides a moving space for the movement of the safety pin 9.

[0029] Please refer specifically to Figure 1 and Figure 3 , One end of the connecting handle 10 is fixedly connected to the outer periphery of the connecting plate 8. A sliding groove 4 for the connecting handle 10 to slide up and down is provided on the rotating buckle 2, and the inner cavity of the sliding groove 4 is communicated with the inner cavity of the accommodating groove 6.

[0030] In this embodiment: When the connecting handle 10 moves up and down, the connecting handle 10 slides along the sliding groove 4, thus ensuring the smooth movement and reset of the connecting handle 10;

[0031] The connecting handle 10 can also be set to be threadedly connected to the connecting plate 8. Specifically: A screw hole is provided at the position where the connecting plate 8 is aligned with the sliding groove 4, and an external thread that matches the thread is provided on the thin rod portion of the connecting handle 10. Through this detachable threaded connection method, after the safety rope is connected, the connecting handle 10 can be removed to avoid the accidental opening of the safety mechanism caused by the force on the connecting handle 10.

[0032] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
