The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Example 1

[0029] Reference Figure 1 and Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a reinforced hook mechanism, which includes a mounting assembly 200 and an anti-falling assembly 300. The cooperation of the two can make the hook more stably installed, prevent the objects hung on the hook from falling off, and improve the safety of the hook.

[0030] Specifically, the installation assembly 200 includes a ring 201a, a linkage ring 201b, a connecting plate 201c and a positioning plate 201d. The linkage ring 201b is located on one side of the ring 201a. One end of the connecting plate 201c is movably connected to the ring 201a, and the other end is movably connected to the linkage ring 201b. The connecting plate 201c is fixed to the surface of the connecting plate 201c.

[0031] After the collar 201a is sleeved on the surface of the hook 101a, the linkage ring 201b moves to one side, driving the connecting plate 201c to move to one side. When the connecting plate 201c moves, it drives the positioning plate 201d to move and merge with the collar 201a to complete the installation.

[0032] Specifically, the anti-detachment component 300 is disposed on one side of the collar 201a and includes a fixing frame 301a, a swing plate 301b, a first spring 301c, and a moving frame 301d. The fixing frame 301a is fixed to one side of the collar 201a. The swing plate 301b is movably connected to the fixing frame 301a. One end of the first spring 301c is fixed to one side of the fixing frame 301a, and the other end is fixed to one side of the swing plate 301b. The moving frame 301d is located at the bottom of the collar 201a.

[0033] The fixing frame 301a and the swing plate 301b are connected by a bearing, and the swing plate 301b can swing within the fixing frame 301a. When one end of the swing plate 301b moves toward the moving frame 301d and is limited by the moving frame 301d, the first spring 301c fixed to the other end of the swing plate 301b will be deformed by force. After the moving frame 301d moves downward, the limitation on the swing plate 301b will be released. At this time, the first spring 301c will reset, and one end of the swing plate 301b will fit with the hook 101a to perform the anti-detachment operation.

[0034] Embodiment 2

[0035] Referring to Figures 2 to 4 , this is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0036] Specifically, a fixing rod 202a is provided on one side of the collar 201a, and a first limit pin 202b is provided inside the fixing rod 202a.

[0037] An installation hole is provided on the surface of the hook 101a. After the collar 201a is sleeved on the surface of the hook 101a, the fixing rod 202a will contact the installation hole. At this time, the first limit pin 202b will be inserted into the hole to complete the first limit and prevent the collar 201a from falling off after installation.

[0038] Specifically, a groove 201a-1 is provided on the surface of the collar 201a, and a second limit pin 202c is provided inside the groove 201a-1.

[0039] The positioning plate 201d is provided with a hole, and the second limit pin 202c is inserted and connected to the hole. After the positioning plate 201d moves toward the surface of the collar 201a, it will fit with the groove 201a-1. At this time, the second limit pin 202c will be inserted into the hole to limit the positioning plate 201d and complete the second limit, increasing the stability of the collar 201a attached to the surface of the hook 101a.

[0040] Specifically, a fixing block 302a is provided on one side of the fixing frame 301a.

[0041] The fixing block 302a is used to cooperate with subsequent parts to complete the function of movement.

[0042] Specifically, there are two fixing blocks 302a, which are symmetrically fixed on the side of the fixing frame 301a.

[0043] The two fixing blocks 302a can improve the stability of subsequent parts through linkage.

[0044] Specifically, a chute 302a-1 is formed in the fixing block 302a, a sliding block 302b is arranged in the chute 302a-1, and a second spring 302c is arranged at the bottom of the sliding block 302b.

[0045] When the hook 101a rises, the moving frame 301d will move downward due to the lifted heavy object. The movement of the moving frame 301d will drive the sliding block 302b to move downward together. At this time, the second spring 302c is deformed by the force. When the heavy object lands and the rope binding the heavy object is lifted, the second spring 302c will reset. At this time, the sliding block 302b will be lifted, and the sliding block 302b will lift the moving frame 301d to reset. Then, the swing plate 301b is moved toward the moving frame 301d side, and the reset can be completed. At this time, the rope can be removed.

[0046] Embodiment 3

[0047] Refer to Figure 4 and Figure 5 , which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.

[0048] Specifically, a connecting rod 302d is arranged on one side of the sliding block 302b.

[0049] One side of the connecting rod 302d is fixed to one side of the sliding block 302b, and one end of the connecting rod 302d is fixed to the top of the moving frame 301d. When the moving frame 301d moves downward, the sliding block 302b is driven to move downward through the connecting rod 302d. When the second spring 302c resets and drives the sliding block 302b to rise, the moving frame 301d is lifted through the connecting rod 302d.

[0050] Specifically, a notch 301d-1 is formed in the moving frame 301d, a limiting block 303a is arranged in the notch 301d-1, and a third spring 303b is arranged at the bottom of the limiting block 303a.

[0051] One end of the limiting block 303a is beveled. When the swing plate 301b moves toward the moving frame 301d side, the swing plate 301b will contact the limiting block 303a, and the limiting block 303a will move downward under the force. When the third spring 303b lifts the limiting block 303a, the swing plate 301b can be limited.

[0052] Specifically, a pushing block 303c is arranged on one side of the swing plate 301b.

[0053] One end of the pushing block 303c is a slope, which moves the swing plate 301b to one side. The swing plate 301b drives the pushing block 303c to move. The slope of the pushing block 303c contacts the slope of the limiting block 303a and pushes the limiting block 303a downward. When the slopes of the pushing block 303c and the limiting block 303a separate, the limiting block 303a is lifted by the third spring 303b and positions the pushing block 303c. At this time, the swing plate 301b is positioned. When the moving frame 301d moves downward, it drives the limiting block 303a to move downward together. At this time, the limiting block 303a separates from the pushing block 303c. After the pushing block 303c loses its position limit, the first spring 301c resets, and one end of the swing plate 301b fits against the hook 101a to perform the anti-dropping operation.

[0054] Specifically, it further includes a main body assembly 100, including a hook 101a.

[0055] The hook 101a is used to lift a heavy object and transfer it to another position.

[0056] During use, after the collar 201a is sleeved on the surface of the hook 101a, the fixing rod 202a contacts the mounting hole. At this time, the first limit pin 202b is inserted into the hole to complete the first limit. Then the linkage ring 201b moves to one side, driving the connecting plate 201c to move to one side. Then when the connecting plate 201c moves, it drives the positioning plate 201d to move and merge with the collar 201a. Then the positioning plate 201d fits against the groove 201a-1. At this time, the second limit pin 202c is inserted into the hole to position the positioning plate 201d and complete the second limit.

[0057] When one end of the swing plate 301b moves towards the moving frame 301d, the swing plate 301b drives the pushing block 303c to move. The slope of the pushing block 303c contacts the slope of the limiting block 303a and pushes the limiting block 303a downward. When the slopes of the pushing block 303c and the limiting block 303a separate, the limiting block 303a is lifted by the third spring 303b and positions the pushing block 303c. At this time, the swing plate 301b is positioned. At the same time, the first spring 301c fixed to the other end of the swing plate 301b is deformed by the force.

[0058] After the item is loaded, the hook 101a is activated. The gravity of the item presses the moving frame 301d downward. When the moving frame 301d moves downward, it drives the sliding block 302b to move downward through the connecting rod 302d. When the moving frame 301d moves downward, it drives the limiting block 303a to move downward together. At this time, the limiting block 303a separates from the pushing block 303c. After the pushing block 303c loses its position limit, the first spring 301c resets, and one end of the swing plate 301b fits against the hook 101a to perform the anti-dropping operation.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
