[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-6 As shown, this utility model provides an anti-detachment lifting sling connection structure, including a connector 1. A hook 2 is fixedly connected to the bottom of the connector 1. An arc-shaped retaining ring 3 is provided inside the connector 1. A connecting block 4 is fixedly connected to the top of one end of the hook 2. A cavity is opened inside the connecting block 4. Two sleeves 5 are fixedly connected to the inner wall of the connecting block 4. A moving rod 6 is slidably connected to the inner wall of each of the two sleeves 5. A first retaining block 7 is fixedly connected to the opposite end of each of the two moving rods 6. A tray 8 is fixedly connected to the outer wall of the sleeves 5 and the outer wall of the moving rod 6. The opposite end of each of the two trays 8 is connected to the two ends of the same first spring 9. A second retaining block 10 is fixedly connected to the bottom of the arc-shaped retaining ring 3. A support plate 11 is fixedly connected to the outer wall of the connector 1.

[0026] The connector 1 has a movable groove inside. One end of the arc-shaped retaining ring 3 is fixedly connected to the arc-shaped plate 12, and one end of the arc-shaped plate 12 is fixedly connected to the guide block 14. The top of the support plate 11 is fixedly connected to the support frame 13, and the top of the support frame 13 is fixedly connected to the arc surface of the guide plate 15. The guide block 14 is slidably connected to the inner wall of the guide plate 15. By setting the guide block 14 and the guide plate 15, the displacement angle of the arc-shaped plate 12 can be guided, so that the arc-shaped plate 12 can drive the arc-shaped retaining ring 3 and the second retaining block 10 to be accurately inserted into the connector 4.

[0027] The inclined surface of the support plate 11 has a limiting groove. One end of the support plate 11 is fixedly connected to a fixing block 16, and one end of the fixing block 16 is fixedly connected to a second spring 17. One end of the second spring 17 is fixedly connected to a limiting plate 18. By setting the second spring 17 and the limiting plate 18, the arc plate 12 can be limited, so as to prevent the arc plate 12 from shaking during the hoisting of the object and causing the arc-shaped retaining ring 3 to loosen.

[0028] A first connecting plate 19 is fixedly connected to the top of the connector 1. A rotating rod 24 is fixedly connected to the top of the first connecting plate 19. The rotating rod 24 is rotatably connected to the second connecting plate 20 through a bearing. A number of first threaded holes 21 are equidistantly opened inside the first connecting plate 19. A second threaded hole 22 is opened inside the second connecting plate 20. The shape of the first threaded hole 21 matches the shape of the second threaded hole 22. The first threaded hole 21 and the second threaded hole 22 are threadedly connected by the same threaded rod 23. By setting the rotating rod 24, the angle of the first support plate can be adjusted, thereby adjusting the angle of the hook 2. This allows for convenient and flexible adjustment of the horizontal angle of the lifting sling, facilitating the installation of the workpiece. Furthermore, the first threaded hole 21, the second threaded hole 22, and the threaded rod 23 can cooperate to lock the adjusted angle, preventing the object from shaking during the lifting and transportation process. The top of the first locking block 7 is set as an inclined surface, and both sides of the second locking block 10 are set as inclined surfaces.

[0029] Working principle:

[0030] In use, first connect the object to be hoisted to the hook 2, then move the guide block 14 along the inner wall of the guide plate 15. The guide block 14 drives the arc plate 12 to move, and the arc plate 12 moves the arc retaining ring 3. The arc retaining ring 3 drives the second retaining block 10 to insert into the connecting block 4. Since the second retaining block 10 and the first retaining block 7 are both inclined surfaces, when the second retaining block 10 is inserted into the connecting block 4, the inclined surfaces on both sides of the second retaining block 10 will squeeze the two first retaining blocks 7. After being compressed, the first retaining blocks 7 will drive the moving rod 6 to move. The moving rod 6 moves along the sleeve 5. During the process, the first spring 9 is compressed, causing it to contract, and the two first locking blocks 7 move away from each other. Then, the second locking block 10 continues to be inserted downwards and separates from the two first locking blocks 7. As a result, the two first locking blocks 7 are reset under the action of the first spring 9. The bottom of the two first locking blocks 7 and the top of the second locking block 10 limit the movement, thereby fixing the arc-shaped locking ring 3 and the connecting block 4, thus sealing the hook 2. When disassembly is required, pull the two moving rods 6 to move the two first locking blocks 7 away, and then pull out the arc-shaped locking block and the second locking block 10.

[0031] 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.
