In this way, the buckle lock tongue 2 is not easy to disengage from its position even under extreme conditions, ensuring the stability and safety of the buckle. At the same time, the sleeve locking groove 11 is an inwardly recessed structure, and the buckle lock tongue 2 arranged in the sleeve locking groove 11 is used to prevent the lock post sleeve 7 from rotating. Through such a structure, when the buckle is subjected to pressure or impact, the cooperation of the lock post sleeve 7 and the buckle lock tongue 2 can ensure that the opening structure of the buckle remains tightly closed, avoiding accidental opening.

[0035] Further, the width of the lock tongue accommodating cavity is slightly larger than the thickness of the buckle lock tongue 2, so that when it is necessary to rotate the lock post sleeve 7, the buckle lock tongue 2 can be pressed close to the lock post stop groove 5 and away from the sleeve locking groove 11 by pressing the swing lock post 4, and then the lock post sleeve 7 can be rotated to the desired position. This operation is simple and fast, which not only ensures the safety of the use of the connection buckle, but also improves the convenience of operation.

[0036] Referring to Figure 4 and Figure 7In the embodiment of the present application, the lock post sleeve 7 is provided with a lock tongue passing groove 10, which is used to pass the shackle lock tongue 2 when the swing lock post 4 is pressed, so as to open the opening structure. The lock tongue passing groove 10 is an opening structure provided on the lock post sleeve 7, and the opening width is greater than the width of the shackle lock tongue 2, so that when the lock post sleeve 7 is rotated to the position where the shackle lock tongue 2 corresponds to the lock tongue passing groove 10, the shackle lock tongue 2 is passed by pressing the swing lock post 4 towards the inside of the shackle body 1, thereby opening the opening structure of the shackle, and achieving quick unlocking. This design not only ensures the quick separation of the equipment in emergency situations, but also enhances the reliability of the shackle structure in regular use.

[0037] In the embodiment of the present application, the lock post sleeve 7 and the swing lock post 4 are provided with a sleeve reset spring 8, which is used to automatically reset the lock post sleeve 7 after it is rotated relative to the swing lock post 4. The design of this reset spring ensures that the lock post sleeve 7 can quickly return to the initial state after rotation.

[0038] In the embodiment of the present application, the swing lock post 4 is connected to the shackle body 1 by a pin, so that the swing lock can rotate relative to the pin, and the opening and closing of the opening structure on the shackle body 1 are realized.

[0039] Referring to Figure 1 In the embodiment of the present application, the connecting end of the swing lock post 4 and the shackle body 1 is provided with a lock post reset spring 6, which is used to automatically reset the swing lock post 4 after it is pressed. The lock post reset spring can be provided on the pin, and its function is to automatically restore the initial position of the swing lock post 4 after it is pressed, thereby ensuring that the connecting shackle can maintain a stable locking state after each use.

[0040] In the embodiment of the present application, the lock post sleeve 7 is provided with a sleeve limiting groove 9 for limiting the rotation angle of the lock post sleeve 7 relative to the swing lock post 4, and the pin is arranged in the sleeve limiting groove 9. The shape of the sleeve limiting groove 9 and the lock post pin 3 protruding in the sleeve limiting groove 9 jointly limit the rotation angle of the lock post sleeve 7, so that the lock post sleeve 7 stops at the position where the sleeve locking groove 11 on the inner side thereof corresponds to the shackle lock tongue 2 before rotation, and the lock post sleeve 7 stops at the position where the lock tongue passing groove 10 corresponds to the shackle lock tongue 2 after rotation.

[0041] In the embodiment of the present application, the lock post sleeve 7 is provided with an unlocking limiting groove 12, which is used to accommodate the connecting shackle when the swing lock post 4 is pressed. Specifically, a flat structure is provided at a corresponding position on the connecting shackle, and after the lock post sleeve 7 is rotated and the swing lock post 4 is pressed to swing towards the inside of the connecting shackle, the flat structure at one end of the connecting shackle enters the unlocking limiting groove 12.

[0042] The embodiment of the second aspect of the application provides a wearable safety protection equipment, and the anti-falling connecting buckle ring of the wearable safety protection equipment.

[0043] Referring to Figure 7 The use mode of the utility model is:

[0044] The connecting buckle ring is integrally pressed into a non-closed C-shaped ring by a long columnar alloy, and a rope, a protection point or other equipment can be placed in the non-closed C-shaped ring and connected through the C-shaped ring. One end of the connecting buckle ring is processed to form a flat buckle tongue 2, and the other end is connected with the connecting buckle ring by a swing lock column 4 and a lock column pin 3. When the buckle tongue 2 is located in the lock column stop groove 5 at the end of the swing lock column 4 away from the lock column pin 3, the swing lock column 4 forms a closed ring with the connecting buckle ring, and the rope, the protection point or other equipment in the connecting buckle ring cannot be accidentally taken out.

[0045] Pressing the swing lock column 4 can make it swing a limited distance in the inner side of the connecting buckle ring with the lock column pin 3 as the axis, so that the connecting buckle ring assumes a non-closed 'C' shape, and the rope, the protection point or other equipment can be placed into or taken out of the connecting buckle ring. Under the pushing of the lock column reset spring 6 at the end of the swing lock column 4 close to the lock column pin 3, the swing lock column 4 can be restored to the position of forming a closed ring with the connecting buckle ring.

[0046] The outer side of the swing lock column 4 is sleeved with a lock column outer sleeve 7 that can rotate a limited distance therearound, and the lock column outer sleeve 7 blocks the buckle tongue 2 from being taken out of the lock column stop groove 5 at one end of the swing lock column 4, so that the connecting buckle ring and the swing lock column 4 cannot form a closed ring together when the swing lock column 4 cannot be pressed.

[0047] The inner side of the lock column outer sleeve 7 away from the lock column pin 3 is provided with an outer sleeve locking groove 11, and the buckle tongue 2 will enter the outer sleeve locking groove 11 when the swing lock column 4 is pressed. The buckle tongue 2 in the outer sleeve locking groove 11 can prevent the rotation of the lock column outer sleeve 7.

[0048] When the lock tongue passing groove 10 at the end of the lock column outer sleeve 7 away from the lock column pin 3 overlaps with the lock column stop groove 5 at the end of the swing lock column 4 away from the lock column pin 3, the buckle tongue 2 can pass through the lock tongue passing groove 10 and be taken out of the lock column stop groove 5 by pressing the swing lock column 4, and the connecting buckle ring can assume a non-closed C shape by further swinging the swing lock column 4 into the inner side of the connecting buckle ring to place the rope, the protection point or other equipment into or take them out.

[0049] The lock post sleeve 7 is provided with a sleeve limiting slot 9 near one end of the lock post pin 3. The shape of the sleeve limiting slot 9 limits the rotation angle of the lock post sleeve 7 under the joint action of the lock post pin 3 protruding in the sleeve limiting slot 9, so that the lock post sleeve 7 before rotation stops at a position corresponding to the sleeve locking slot 11 on the inner side of the lock post sleeve 7 and the shackle lock tongue 2, and the lock post sleeve 7 after rotation stops at a position corresponding to the shackle lock tongue 2 through the slot 10. The sleeve reset spring 8 is located between the swing lock post 4 and the lock post sleeve 7, which can make the lock post sleeve 7 rotate and recover to the position corresponding to the sleeve locking slot 11 on the inner side of the lock post sleeve 7 and the shackle lock tongue 2.

[0050] After rotating the lock post sleeve 7, press the swing lock post 4 to swing to the inside of the connecting shackle. The flat structure at one end of the connecting shackle will enter the unlocking limiting slot 12 away from the lock post pin 3 of the lock post sleeve 7. At this time, the unlocking limiting slot 12 can prevent the lock post sleeve 7 from rotating to the initial position under the action of the sleeve reset spring 8. Without external force, the swing lock post 4 recovers to form a closed ring with the connecting shackle under the action of the lock post reset spring 6. At this time, the flat structure at one end of the connecting shackle leaves the unlocking limiting slot 12, and the lock post sleeve 7 rotates to recover to the initial position corresponding to the sleeve locking slot 11 and the shackle lock tongue 2 under the action of the sleeve reset spring 8.

[0051] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and embodiments having the same technical idea and playing the same role and effect within the scope of the technical solution of the present application are all included in the technical scope of the present application.
