[0025] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0026] This embodiment mainly describes an anti-unhooking safety protection structure that facilitates unhooking, as follows:

[0027] like Figures 1 to 5As shown, an anti-unhooking safety protection structure that is easy to unhook includes a hook body 1, wherein the hook body 1 has a connecting arm 4 and a bent portion 3, the lower end of the connecting arm 4 is connected to the bent portion 3, the connecting arm 4 is connected to a lifter or other equipment that requires the hook to be assembled, the bent portion 3 has an upward hanging opening 2, and objects that need to be moved and transported can be hung on the hook body 1 through the hanging opening 2, an anti-unhook member 6 is hinged on the hook body 1, and the movable end of the anti-unhook member 6 is always located in the hanging opening 2, and a counterweight structure is provided on the anti-unhook member 6, which enables the anti-unhook member 6 to rotate around the hinge point and press firmly against the bent portion 3 to close the hanging opening 2. When the anti-drop hook is in use, the object to be moved and transported is hung on the hook body from the hanging opening 2. Under the action of the weight of the counterweight structure itself, the anti-drop component 6 is driven to rotate around the hinge point to close the hanging opening 2 to prevent the hook body 1 from being unhooked. When the object to be moved and transported needs to be removed, the push rod is used to push the counterweight structure to rotate upward, driving the anti-drop component 6 to rotate around the hinge point into the hanging opening 2, thereby opening the hanging opening 2 and moving the hook body 1 to separate the hook body 1 from the object.

[0028] like Figures 1 to 4 As shown, the bending portion 3 includes a first bending portion 31 , a second bending portion 32 and a third bending portion 33 . The first bending portion 31 and the third bending portion 33 have opposite bending directions and form the hanging opening 2 .

A counterweight block 65 is provided at one end of the rotating arm 61 away from the anti-slip component 6. Under the action of gravity of the rotating arm 61 and the counterweight block 65, the anti-slip component 6 can be given a force to rotate around the hinge point toward the third bend 33 and press firmly against the third bend 33, so that the anti-slip component 6 and the third bend 33 can cooperate to close the hanging mouth 2.

[0030] Preferably, a first avoidance groove 66 is provided on the side of the counterweight block 65 close to the curved portion 3, and the first avoidance groove 66 cooperates with the outer wall of the curved portion 3. The setting of the first avoidance groove 66 can further exert the gravity of the counterweight block 65 to make the anti-slip component 6 completely closed, thereby preventing the curved portion 3 from removing part of the gravity of the counterweight block 65 and causing the hanging mouth 2 to be unable to be completely closed.

[0031] like Figures 1 to 4 As shown, the connecting arm 4 is provided with a protrusion 5, and the anti-slip component 6 is hinged on the protrusion 5 of the connecting arm 4. Specifically, the protrusion 5 is provided with a hinge hole, and the intersection of the anti-slip component 6 and the rotating arm 61 is provided with a connecting hole corresponding to the hinge hole, and the latch 7 passes through the connecting hole and the hinge hole to hinge the anti-slip component 6 with the protrusion 5. Nuts 8 for limiting the anti-slip component 6 are threadedly connected on both sides of the latch 7 to prevent the latch 7 from falling off during use.

[0032] Preferably, the anti-slip member 6 is provided with a first U-shaped opening 63, and the first U-shaped opening 63 is used to prevent the anti-slip member 6 from interfering with the first curved portion 31 when the hanging opening 2 is opened, so that the hanging opening 2 can be fully opened, which is also applicable to objects with different hooking parts. The rotating arm 61 is provided with a second U-shaped opening 64, and the rotating arm 61 is mounted on the hook body 1 through the second U-shaped opening 64.

[0033] A second avoidance groove 67 is provided at the end of the anti-slip component 6, and the second avoidance groove 67 is clamped on the third curved portion 33 and firmly abutted against the third curved portion 33. The third curved portion 33 is firmly abutted in the second avoidance groove 67, which can enhance the stability of the anti-slip hook during use and avoid the anti-slip component 6 from being offset during use.

[0034] like Figure 5 As shown, the anti-slip member 6 and the rotating arm 61 form an L shape and a V shape, and the connecting hole is located at the corner between the anti-slip member 6 and the rotating arm 61 .

[0035] Preferably, the side of the protrusion 5 close to the hanging opening 2 is a smooth curved surface, and the free end of the third curved portion 33 is a smooth curved surface, so as to prevent the object from being worn when being hooked, thereby reducing the service life of the object.
