Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Referring to Figures 1 to 4 , the present utility model discloses a rigging hook with a self-release function, including:

[0031] The main boards 4, there are two main boards 4, the main boards 4 are integrally formed by a vertical plate 401 and a baffle 402, the baffle 402 is located at the bottom of the vertical plate 401, and the axes of the vertical plate 401 and the baffle 402 are arranged in a spatially crossed manner;

[0032] The suspension part, located at the tops of the two vertical plates 401, and the two vertical plates 401 are rotatably connected to the bottom of the same suspension part;

[0033] The magnetic attraction part, fixedly connected between the two vertical plates 401, located in the middle of the vertical plate 401 and close to the suspension part;

[0034] The hook plate 8, located between the two vertical plates 401, a pin 9 is rotatably connected to the middle of the hook plate 8, and both ends of the pin 9 are fixedly connected to the bottom of the corresponding vertical plate 401. The top of the hook plate 8 is magnetically attracted and matched with the magnetic attraction part. When the hook plate 8 hangs an object, the baffle 402 is used to prevent the object hung on the hook plate 8 from falling off.

[0035] During use, after hooking an item with the hook plate 8, the entire device is lifted by hoisting the suspension part with a hoist. Before the item is lifted off, the baffle 402 blocks above the hook groove of the hook plate 8 to prevent the item from disengaging from the hook plate 8. At this time, the top of the hook plate 8 is magnetically engaged with the magnetic attraction part. When the hook plate 8 rises, under the action of the gravity of the item, the magnetic attraction part and the top of the hook plate 8 are naturally separated. When the item is transported to the designated position, under the action of its own centroid, the hook plate 8 rotates around the pin shaft 9, and after the hook plate 8 flips, the item disengages itself, completing the transportation.

[0036] In a further optimized solution, the suspension part includes a shackle body 1, and the tops of the two vertical plates 401 are rotatably connected to the bottom of the shackle body 1.

[0037] In a further optimized solution, a bushing 2 is fixedly connected between the tops of the two vertical plates 401. A shackle pin 3 is sleeved in the bushing 2, and the shackle pin 3 is rotatably connected to the bushing 2. The two ends of the shackle pin 3 respectively penetrate the side walls of the corresponding vertical plates 401, and the two ends of the shackle pin 3 penetrate the bottom end of the shackle body 1. The shackle body 1 is rotatably connected to the shackle pin 3, and the shackle body 1 and the shackle pin 3 are vertically limited and matched.

[0038] The shackle body 1 is used to connect with hoisting equipment. The bushing 2 is fixedly connected between the two vertical plates 401 and is located at the top of the vertical plates 401. The shackle pin 3 penetrates the two vertical plates 401 and is rotatably connected to the bushing 2. The two ends of the shackle pin 3 are rotatably connected to the shackle body 1 and are vertically limited and matched with the shackle body 1.

[0039] In a further optimized solution, the magnetic attraction part includes a magnet fastening plate 5. The magnet fastening plate 5 is fixedly connected between the two vertical plates 401 by bolts 6, and the magnet fastening plate 5 is arranged close to the shackle pin 3;

[0040] One end of the magnet fastening plate 5 close to the top of the hook plate 8 is embedded with a strong magnet 7, and the strong magnet 7 is magnetically connected to the top of the hook plate 8.

[0041] During use, when the hook plate 8 is hooked to the item, before hoisting, the top of the hook plate 8 is adsorbed by the strong magnet 7. During hoisting, the hook plate 8 is naturally plumb under the action of the gravity of the item, and its top is separated from the strong magnet 7. When the item moves to the designated position, as the gravity of the item acting on the hook plate 8 decreases to zero, the hook plate 8 rotates by itself under the action of its own centroid, realizing automatic unhooking of the item.

[0042] The magnet fastening plate 5 is fixedly connected between the two vertical plates 401 by bolts 6. By removing the bolts 6, the magnet fastening plate 5 can be replaced, which is convenient for later maintenance and servicing.

[0043] In a further optimized solution, the hook plate 8 includes a mounting plate 801, and the middle of the mounting plate 801 is rotatably connected to the bottoms of the two vertical plates 401 through a pin shaft 9;

[0044] A hook 804 is provided at the bottom of the mounting plate 801;

[0045] A semicircular gravity plate 802 is provided on one side of the top of the mounting plate 801, and the top of the semicircular gravity plate 802 exceeds the top of the mounting plate 801 to form a clearance groove 803;

[0046] The mounting plate 801, the semicircular gravity plate 802 and the hook 804 are integrally formed.

[0047] A hook 804 is provided at the bottom of the mounting plate 801, and a semicircular gravity plate 802 is provided on one side of the top of the mounting plate 801. The top of the semicircular gravity plate 802 exceeds the top of the mounting plate 801 to form a clearance groove 803. The strong magnet 7 is magnetically connected to one side of the top of the semicircular gravity plate 802. The clearance groove 803 allows the strong magnet 7 and the magnet fastening plate 5 to pass through when the hook 804 hooks an object, thereby ensuring that the mounting plate 801 is in a vertical state when hooking an object.

[0048] The semicircular gravity plate 802 causes the center of mass of the hook plate 8 to shift away from the pin shaft 9 and the hook 804, so that after the item is delivered to the right position, as the force acting on the item decreases to zero, the hook plate 8 as a whole can rotate around the pin shaft 9 under the action of the semicircular gravity plate 802. At this time, the hook 804 flips direction to unhook the item.

[0049] During the preparation for the lifting operation, the top of the hook plate 8 is magnetically attracted by the strong magnet 7, and the hook groove of the hook 804 is blocked by the baffle 402 to prevent the item from being unhooked. During the lifting process, the hook plate 8 naturally plumbs under the action of the gravity of the item, and its top is separated from the strong magnet 7. When the item is transported to the designated position, as the gravity of the item acting on the hook plate 8 decreases to zero, the hook plate 8 rotates automatically under the action of its own center of mass, causing the item to automatically unhook.

[0050] According to a further optimization scheme, the radius of the semicircular gravity plate 802 is 70 mm, and the bottom of the semicircular gravity plate 802 and the top of the hook 804 are smoothly transitioned.

[0051] According to a further optimized solution, the angle between the vertical plate 401 and the baffle 402 is 94.6°.

[0052] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0053] The embodiments described above are only descriptions of the preferred embodiments of the present utility model, and do not limit the scope of the present utility model. Without departing from the design spirit of the present utility model, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope determined by the claims of the present utility model.
