Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic decoupling devices, in particular to a magnetic automatic decoupling device. Background Art
[0002] Currently, all domestic ports use automatic unhooking devices for loading and unloading. These devices are of the marble type, but they share a common disadvantage: they are difficult to maintain. Long-term use at the dock leads to corrosion and rusting of the marbles and springs, resulting in insufficient elasticity, making them unable to lock and function properly. These devices must be replaced with new ones, essentially becoming consumables. This addresses the issues of high cost, long procurement and production cycles, and reduced usability. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, a magnetic automatic decoupling device is provided.
[0004] The hook is hinged to the lower end of the hook splint arm through a hook hinge shaft, and a magnet is fixed on the hook splint arm to magnetically attract the upper end of the hook so that the hook maintains a ready state with the hook head facing downward, which is convenient for hooking the goods. When the goods are hooked, the hook is straightened under the action of gravity (that is, the upper end of the hook is separated from the magnet), and then when the goods fall to the ground, the upper end of the hook is heavier and reverses itself so that the hook head is separated from the goods to achieve the unhooking action.
[0005] Preferably, a magnet is fixed on the side of the hook clamp arm by a bolt or a set screw for magnetic attraction with the upper end plane of the hook.
[0006] Preferably, a plurality of magnet grooves are provided on the inner side wall of the hook clamp arm, and magnets are fixed in the magnet grooves for magnetically attracting the side wall of the hook.
[0007] Preferably, a limiting bolt for preventing reverse rotation is fixedly provided on the hook clamp arm, and the limiting bolt passes through the hook clamp arm and is fixed by a nut.
[0008] The advantages and positive effects of the present invention are that the automatic unhooking device is designed to be maintenance-free during use and to extend the service life of the unhooking device, thereby complying with safe and civilized production and achieving the effect of reducing costs and increasing efficiency.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating the basic structure of the present invention in a schematic manner, and therefore only show components relevant to the present invention. The following is a further detailed description of embodiments of the present invention with reference to the accompanying drawings:
[0016] like Figure 1-4 As shown, the magnetic automatic unhooking device described in the present invention includes a hook clamp arm 16 and a lifting ring 14 bolted to the upper end of the hook clamp arm 16, and a hook 10 is hingedly provided at the lower end of the hook clamp arm 16 through a hook hinge shaft 13, and a magnet is fixed on the hook clamp arm 16 for magnetically attracting the upper end of the hook 10 so that the hook 10 maintains a ready state with the hook head facing downward, which is convenient for hooking the goods. When the goods are hooked, the hook 10 is straightened under the action of gravity (that is, the upper end of the hook 10 is separated from the magnet), and then when the goods fall to the ground, the upper end of the hook 10 is heavier and reverses itself so that the hook head is separated from the goods to realize the unhooking action.
[0017] Preferably, a magnet 11 is fixed on the side of the hook clamp arm 16 by a bolt or a set screw for magnetic attraction with the upper end plane of the hook 10 (such as Figure 2 ).
[0018] Preferably, a plurality of magnet grooves 15 are provided on the inner side wall of the hook clamp arm 16, and magnets are fixed in the magnet grooves 15 for magnetically attracting the side wall of the hook 10 (such as Figure 4 ).
[0019] Preferably, a limiting bolt 12 for preventing reverse rotation is fixed on the hook clamp arm 16 , and the limiting bolt 12 passes through the hook clamp arm 16 and is fixed by a nut.
[0020] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
