[0032] This utility model discloses a lifting fixture for lifting electrical appliance display racks or objects whose center of gravity is not located at the geometric center. The following description uses an electrical appliance display rack as an example of the object to be lifted. Figure 1As shown, the lifting fixture disclosed in this utility model includes a lifting rod 1 and a first lifting assembly 2 and a second lifting assembly 3 disposed on the lifting rod 1. The first lifting assembly 2 and the second lifting assembly 3 are spaced apart on the lifting rod 1, and at least one position of the first lifting assembly 2 and the second lifting assembly 3 is adjustablely disposed on the lifting rod 1. The first lifting assembly 2 includes a first hook 21, and the second lifting assembly 3 includes a second hook 31. Both the first hook 21 and the second hook 31 are disposed on the same side of the lifting rod 1, and the lengths of the first hook 21 and the second hook 31 are different. It can be understood that the lifting fixture is connected to the lifting points on both sides of the electrical appliance display rack via slings through the first hook 21 of the first lifting assembly 2 and the second hook 31 of the second lifting assembly 3. Before hoisting, select hoisting components of appropriate specifications according to the specifications of the appliance display rack. By setting hooks of different lengths for the first hoisting component 2 and the second hoisting component 3, the center of gravity of the appliance display rack is initially stabilized and balanced. Then, a trial hoisting is carried out. If the appliance display rack is unstable and tilts during the trial hoisting, the appliance display rack can be lowered first, and the position of the first hoisting component 2 or the second hoisting component 3 on the hoisting rod 1 can be further adjusted. The hoisting components are then readjusted to match the center of gravity of the appliance display rack, and finally, a stable hoisting is achieved without the need to repeatedly replace the hoisting components to adapt, which can quickly improve work efficiency.
[0033] In some embodiments, both the first lifting assembly 2 and the second lifting assembly 3 are detachably connected to the lifting rod 1. It is understood that the first lifting assembly 2 or the second lifting assembly 3 can be quickly installed or removed from the lifting rod 1 as a whole. This configuration ensures that even if the center of gravity of the appliance display rack cannot be matched to maintain its balance under both hook length balance and position adjustment compensation, a quick adjustment and adaptation can be achieved by replacing the first lifting assembly 2 or the second lifting assembly 3 as a whole, eliminating the need for repeated replacement of sliders, lifting rings, and hooks for constant re-matching, thus improving work efficiency. In other embodiments, the first lifting assembly 2 or the second lifting assembly 3 may also be slidably connected to and detachably connected to the lifting rod 1, and locked to the lifting rod 1 by a locking element, which may be a bolt.
[0034] In some embodiments, such as Figure 2 and Figure 4As shown, the first hoisting assembly 2 also includes a first fixing member 22, which is connected to the lifting rod 1, and a first hook 21 is disposed on the first fixing member 22. When the position of the first hoisting assembly 2 is adjustable, the lifting rod 1 has multiple through holes at one end where the first hoisting assembly 2 is disposed, and the multiple through holes are spaced apart along the same horizontal line; the first fixing member 22 has at least two through holes, and the first fixing member 22 is fixedly connected to the lifting rod 1 by a positioning pin 4. It can be understood that by fixing the first hoisting assembly 2 and the lifting rod 1 through the through holes and the positioning pin 4, the first hoisting assembly 2 and the lifting rod 1 are detachably connected, and the position of the first hoisting assembly 2 relative to the lifting rod 1 is also adjustable. By adjusting the position of the first hoisting assembly 2 on the lifting rod 1, the hoisting assembly can be readjusted to match the center of gravity of the electrical appliance display rack, ultimately achieving stable hoisting without the need to repeatedly replace the hoisting assembly for adaptation, which can quickly improve work efficiency.
[0035] In some embodiments, the first lifting assembly 2 further includes a first lifting ring 23; the first hook 21 includes a first main body portion 211 and a first hook portion 212; the first main body portion 211 passes through and is detachably connected to the first fixing member 22, the first hook portion 212 is disposed at one end of the first main body portion 211, and the first lifting ring 23 is disposed at the other end of the first main body portion 211. It is understood that the first main body portion 211 and the first hook portion 212 are integrally formed. The first main body portion 211 and the first fixing member 22 may be threadedly connected, allowing the first hook 21 to be replaceable on the first fixing member 22. The length of the hook can be adjusted by replacing only the first hook 21, thereby saving manufacturing costs for the first lifting assembly 2. The first lifting ring 23 is disposed at the end of the first main body portion 211 away from the first hook 21 portion and is fixedly connected to the first main body portion 211. The lifting device can be connected to the first lifting ring 23 via a sling. In other alternative embodiments, one end of the first main body 211 may also be fixed to and detachably connected to the first fixing member 22, the first hook 212 is disposed at the other end of the first main body 211, and the first lifting ring 23 is disposed on the first fixing member 22. It is understood that the first lifting ring 23 being disposed on the first fixing member 22 can prevent the angle between the ring opening of the first lifting ring 23 and the lifting rod 1 from changing arbitrarily due to errors in the installation angle of the first hook 21, ensuring the consistency of the installation position and direction of the first lifting ring 23, thereby facilitating the assembly of the first lifting assembly 2 and its connection with the lifting device, and also ensuring the stability of the lifting.
[0036] In some embodiments, such as Figure 3 and Figure 4As shown, the second lifting assembly 3 also includes a second fixing member 32, which is connected to the lifting rod 1. A second hook 31 is disposed on the second fixing member 32. When the position of the second lifting assembly 3 is adjustable, the lifting rod 1 has multiple through holes at one end where the second lifting assembly 3 is located, and these through holes are spaced apart along the same horizontal line. The second fixing member 32 has at least two through holes and is fixedly connected to the lifting rod 1 by a positioning pin 4. It can be understood that by fixing the second lifting assembly 3 and the lifting rod 1 through the through holes and the positioning pin 4, the second lifting assembly 3 and the lifting rod 1 can be detachably connected, while also making the position of the second lifting assembly 3 relative to the lifting rod 1 adjustable. By adjusting the position of the second lifting assembly 3 on the lifting rod 1, the lifting assembly can be readjusted to match the center of gravity of the appliance display rack, ultimately achieving stable lifting without the need for repeated replacement of the lifting assembly for adaptation, thus quickly improving work efficiency.
[0037] In other embodiments, the first hoisting assembly 2 and the second hoisting assembly 3 are simultaneously adjustable. This is achieved by providing through holes spaced apart along the entire length of the hoisting rod 1. In other words, the through holes on the hoisting rod 1 are evenly and spaced apart along the length of the hoisting rod 1, and both the first hoisting assembly 2 and the second hoisting assembly 3 can be adjusted in position along the length of the hoisting rod 1.
[0038] In some embodiments, the second lifting assembly 3 further includes a second lifting ring 33; the second hook 31 includes a second main body portion 311 and a second hook portion 312; the second main body portion 311 passes through and is detachably connected to the second fixing member 32, the second hook portion 312 is disposed at one end of the second main body portion 311, and the second lifting ring 33 is disposed at the other end of the second main body portion 311. It is understood that the second main body portion 311 and the second hook portion 312 are integrally formed. The second main body portion 311 and the second fixing member 32 may be threadedly connected, allowing the second hook 31 to be detachable from the second fixing member 32. The length of the second hook 31 can be adjusted by replacing only the second hook 31, thereby saving manufacturing costs for the second lifting assembly 3. The second lifting ring 33 is disposed at the end of the second main body portion 311 away from the second hook 31 portion and is fixedly connected to the second main body portion 311. The lifting device can be connected to the second lifting ring 33 via a sling. In other alternative embodiments, one end of the second main body 311 may also be fixed to and detachably connected to the second fixing member 32, the second hook 312 is disposed at the other end of the second main body 311, and the second lifting ring 33 is disposed on the second fixing member 32. It is understood that the second lifting ring 33 being disposed on the second fixing member 32 can prevent the angle between the ring opening of the second lifting ring 33 and the lifting rod 1 from changing arbitrarily due to errors in the installation angle of the second hook 31, ensuring the consistency of the installation position and direction of the second lifting ring 33, thereby facilitating the assembly of the second lifting assembly 3 and its connection with the lifting device, and also ensuring the stability of the lifting. Optionally, when the first lifting ring 23 is set on the first fixing member 22, the second lifting ring 33 is set on the second fixing member 32; when the first lifting ring 23 is set on the first hook 21, the second lifting ring 33 is set on the second hook 31. In other words, the first lifting assembly 2 and the second lifting assembly 3 have the same structure, the only difference being the length of the first hook 21 and the second hook 31, thereby ensuring the synchronization of the positions of the first lifting ring 23 and the second lifting ring 33, and better ensuring the stability during lifting.
[0039] The lifting fixture disclosed in this utility model is connected to the lifting points on both sides of the appliance display rack via a first hook 21 of the first lifting component 2 and a second hook 31 of the second lifting component 3, respectively, through slings. The lifting device is connected to the first lifting ring 23 and the second lifting ring 33, respectively, through slings. Before lifting, the appropriate lifting components are selected according to the specifications of the appliance display rack. By setting hooks of different lengths on the first lifting component 2 and the second lifting component 3, the center of gravity of the appliance display rack is initially stabilized and balanced. Then, a trial lift is performed. If the appliance display rack is unstable and tilts during the trial lift, the appliance display rack can be lowered first, and the position of the first lifting component 2 or the second lifting component 3 on the lifting rod 1 can be further adjusted. The lifting components are then readjusted to match the center of gravity of the appliance display rack, ultimately achieving stable lifting without the need for repeated replacement of lifting components, thus rapidly improving work efficiency.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
