Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," and the like are used merely to distinguish one description from another, and are not to be construed as indicating or implying relative importance.

In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "up", and the like indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, or the directions or positional relationships that the products of the present invention are conventionally placed when used, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the term refers must have a specific direction, be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-4, the hook unhooking prevention mechanism for the lifting hook comprises two bases 1 fixed at an opening of the lifting hook, anti-falling blocks 2 are movably mounted on one opposite sides of the two bases 1, and an elastic component 3 used for driving the two anti-falling blocks 2 to contact with each other and closing the opening of the lifting hook is arranged on the lifting hook.

In this embodiment, when using, through elastic component 3's setting, when being in the same place the lifting hook with another lifting hook through elastic component 3 with two anticreep pieces 2 on two lifting hooks between the mutual contact and make the opening part of two lifting hooks seal, just can prevent two lifting hooks from the problem that two lifting hook opening parts drop each other, has greatly avoided the lifting hook to drop and has leaded to the problem that the heavy object falls to damage, has strengthened the stability that the lifting hook lifted the heavy object.

Specifically, all be formed with cavity and two bases 1's top and relative one side in two bases 1 and all seted up the opening, two anticreep pieces 2 are placed respectively in two cavities.

In the present example. The cavity that forms in two bases 1 is used for placing anticreep piece 2 in the cavity, and the opening that top and relative one side were seted up is convenient for two anticreep pieces 2's removal.

Specifically, elastic component 3 is including fixing the movable rod 31 in two anticreep piece 2 one side that carry on the back mutually respectively, and the surface of two movable rods 31 all overlaps and is equipped with spring 32, and the one end that anticreep piece 2 was kept away from to two movable rods 31 is the activity respectively and is run through the one end that two bases 1 carried on the back mutually.

In this embodiment, the two anti-dropping blocks 2 abut against each other to close the opening of the hook in a normal state, when the two anti-dropping blocks 2 contact, the two springs 32 are already in a compressed state, when the heavy object is lifted, the lifting ring on the heavy object passes through the opening of the lifting hook on the lifting machine, at the moment, the two anti-drop blocks 2 at the openings of the two lifting hooks are extruded by the lifting ring to enable the two anti-drop blocks 2 to move along the cavities of the two bases 1 in opposite directions, thereby opening the opening of the lifting hook, hanging the lifting ring on the lifting hook, then generating recoil force after the springs 32 sleeved on the movable rods 31 at the two opposite ends of the two anti-falling blocks 2 are extruded, leading the two anti-falling blocks 2 to move towards opposite directions, when two anticreep pieces 2 contacts, the opening part of lifting hook can be closed once more, prevents that rings from coming off from the lifting hook opening part, and the opening of lifting hook can be closed and opened to the personnel that do not need of whole structure removes the operation.

Specifically, two anticreep blocks 2 all are triangle-shaped and are the V type between two anticreep blocks 2 when two anticreep blocks 2 contact.

In this embodiment, when two anticreep pieces 2 are triangle-shaped and are the V type between two anticreep pieces 2, be convenient for with the shackle cooperation, with the shackle through get into in the opening of lifting hook between two anticreep pieces 2.

Specifically, two bases 1 are located on the same side of the lifting hook, wherein one base 1 is fixed on one side of the hook tip of the lifting hook, and the other base 1 is fixed on one side of the hook body which is at the same level with the hook tip of the lifting hook.

In this embodiment, two bases 1 lie in the lifting hook with be convenient for make two anticreep pieces 2 align with the clamp tightly to seal the opening part with the lifting hook with the same one side of lifting hook, when base 1 lies in one side of lifting hook end, two anticreep pieces 2 are the biggest with the area that the lifting hook encloses and closes, can cooperate the relatively great shackle use.

Specifically, the two bases 1 are fixed to the hook by bolts.

In this embodiment, the base 1 and the lifting hook are convenient to detach through the arrangement of the bolts.
