[0036] Example 1:

[0037] As Figures 1-6As shown, a rotating hook convenient for electronic scale adjustment, including a pulley block 1 and a hook 5, an electronic scale 6 is arranged between the pulley block 1 and the hook 5, the lower end of the pulley block 1 is provided with an upper connecting part 2, the upper end of the hook 5 is rotatably installed in the lower part of a lower connecting part 3, the lower connecting part 3 is rotatably installed with a lower rotary connecting rod 301 at the upper end of the hook 5 through a lower rotary shaft 9, the upper connecting part 2 is rotatably installed with an upper rotary connecting rod 201 through an upper rotary shaft 8, the upper end of the electronic scale 6 is provided with an upper connecting seat 601 hinged with the lower end of the upper rotary connecting rod 201, the lower end of the electronic scale 6 is provided with a lower connecting seat 602 hinged with the upper end of the lower rotary connecting rod 301, and a locking device is arranged between the upper connecting part 2 and the lower connecting part 3. The locking device includes a connecting rod 10, which is installed on the outer wall of the part of the lower connecting part 3 extending out of the lower rotary shaft 9 at both ends, and the outer wall of the part of the side wall of the upper connecting part 2 extending out of the upper rotary shaft 8 at both ends is matched with the connecting rod 10.

[0038] Specific working principle: the device is sequentially arranged from top to bottom as the pulley block 1, the upper connecting part 2, the electronic scale 6, the lower connecting part 3 and the hook 5, the upper pulley block 1 is connected with the sling of the crane, and the crane drives the lifting hook to rise and fall; when weighing is needed, the device is unfolded, the electronic scale 6 is connected between the upper connecting part 2 and the lower connecting part 3, the hook 5 at the lower end is used to lift the weight to rise and fall and weigh; when weighing is not needed or is completed, the upper rotary connecting rod 201 and the lower rotary connecting rod 301 are rotated to move the electronic scale 6 away, at this time the lower connecting part 3 at the bottom of the upper connecting part 2 will be raised, through the locking device, the connecting rod 10 on both sides of the lower connecting part 3 is rotated upward to be lapped onto the upper rotary shaft 8 at both ends of the upper connecting part 2 to be buckled tightly, the shape switching of the hook is completed, when lifting the object again, the electronic scale 6 on one side will not be affected by the pulling force of the object, thereby protecting the electronic scale 6; if the device needs to weigh again, the locking device needs to be opened, the connecting rod 10 is rotated downward to be separated from the fixed state with the upper connecting part 2, and the device is naturally lowered to restore the weighing. In the above process, the device can combine the electronic scale 6 and the hook 5, so that they will not be damaged due to too fast or too rapid rotation, and the safety hidden danger is reduced; at the same time, the device does not need to have a complicated electronic scale 6 installation step, the position of the electronic scale 6 can be adjusted to switch between the weighing and non-weighing modes, thereby protecting the electronic scale 6; the electronic scale 6 can be easily removed when not needed to be affected by the pulling force, and can be conveniently restored for weighing when needed to be used, thereby improving the actual use value of the equipment and prolonging the service life of the electronic scale 6.

[0039] Example 2:

[0040] As Figure 5 , Figure 6As shown, as a further optimization of Embodiment 1: a mounting plate 4 is fixed to the lower end of the lower connecting part 3. A first gear 401 is fixedly installed on the outer wall of the portion of the hook 5 that passes through the mounting plate 4. A motor 7 is provided at the upper end of the mounting plate 4. A second gear 402, driven by the motor 7 and meshing with the first gear 401, is rotatably installed inside the mounting plate 4. The output end of the motor 7 is connected to a reducer, and the output end of the reducer extends into the mounting plate 4 and is fixedly connected to the second gear 402. That is, when the motor 7 is started, it drives the second gear 402 to rotate inside the mounting plate 4 through the reducer, and drives the first gear 401 that meshes with it to rotate, thereby driving the hook 5 to rotate. Through the arrangement of the mounting plate 4, the first gear 401, the second gear 402, and other structures, this device can further facilitate the control of the motor 7 to drive the hook 5 to rotate. A counterweight is detachably installed on the upper surface of the mounting plate 4. By setting up counterweights, the center of gravity of this device is not affected by the electronic scale 6, motor 7, and connecting rod 10, thus maintaining balance and improving weighing accuracy.

[0041] Example 3:

[0042] like Figures 1-9 As shown, as a further optimization of Embodiment 1: the upper rotating connecting rod 201 and the lower rotating connecting rod 301 are the same size and shape, the upper connecting seat 601 and the lower connecting seat 602 are the same size and shape, and the fixed installation angle of the connecting rod 10 and the lower rotating connecting rod 301 on the outer wall of the lower rotating shaft 9 is always perpendicular. That is, when the upper rotating connecting rod 201 and the lower rotating connecting rod 301 rotate 90 degrees, the electronic scale 6 can be moved away. During this process, the connecting rod 10, which is fixedly connected to the lower rotating shaft 9, will also rotate upward 90 degrees to connect with the upper rotating shaft 8 on the upper connecting part 2, thus completing the locking between the upper connecting part 2 and the lower connecting part 3. By setting the size and shape of the upper rotating connecting rod 201, the lower rotating connecting rod 301, the upper connecting seat 601, and the lower connecting seat 602, as well as the installation angle between the lower rotating connecting rod and the lower connecting rod, this device can link the switching action and the step of fastening the upper connecting part 2 and the lower connecting part 3 through the connecting rod 10, achieving a one-step operation and making the operation more convenient. A hook 101 is provided at the end of the connecting rod 10 away from the lower rotating shaft 9. The hook 101 is detachably fixed to the fixing buckle 102 by threads. The inner walls of the hook 101 and the fixing buckle 102 are adapted to the outer wall of the upper rotating shaft 8. The hook 101 and the fixing buckle 102 make it easier to operate the connecting rod 10 and to lock the upper connecting part 2 and the lower connecting part 3.

[0043] Example 4:

[0044] like Figures 5-9As shown, as further optimization of embodiment 1: the side wall on the same side of the upper connecting part 2 and the lower connecting part 3 is rotatably installed with a movable side plate 11, and the movable side plate 11 is rotatably installed with movable side plates 1101 on both sides. That is, when the movable side plate 11 is located in the upper connecting part 2 and the lower connecting part 3, the movable side plates 1101 on both sides will extend outward, and when the upper rotating connecting rod 201 and the lower rotating connecting rod 301 rotate, the movable side plate 11 will be pushed out, and the movable side plates 1101 on both sides will fall down, and the movable side plate 11 and the movable side plate 1101 will protect the electronic scale 6 as a whole. Through the structure of the movable side plate 11, the movable side plate 1101 and the like, the device can further protect the electronic scale 6 moved away, or as an offset counterweight, balance the center of gravity of the device.
