Description

Technical Field

[0001] This invention relates to the field of lifting equipment technology, and more specifically, to a hook device. Background Technology

[0002] Existing lifting hook devices typically consist of a hook body and a spring-loaded anti-detachment clip. However, the hook detachment process generally requires ground personnel to operate, which is very inconvenient. Especially during air rescue and drone-based lifting operations, the high-speed rotation of helicopter and drone rotors creates harsh and dangerous environments. Not only is it extremely dangerous for on-site personnel to assist with the detachment operation, but the harsh environment also limits the visibility of pilots and flight operators, and hinders communication between ground and air personnel.

[0003] Chinese patent publication CN106241596B discloses a "spring-loaded automatic unhooking hook device," specifically comprising two symmetrically arranged clamping plates. The lower ends of the two clamping plates are rotatably connected to a hook body via an upper connecting shaft. The hook body has an adjustment groove, within which a lower connecting shaft is slidably connected. Both ends of the lower connecting shaft extend out of the adjustment groove and connect to guide blocks. Rollers are located at both ends of the lower connecting shaft, between the guide blocks and the hook body, with the upper ends of the rollers rollingly connected to the lower end faces of the clamping plates. A spring positioning platform is provided on the hook body, and a spring is fitted onto the hook body, with the lower end of the spring contacting the spring positioning platform and the upper end contacting the lower end face of the guide block. While this patent can automatically unload heavy objects, the lack of a structure to block the opening could pose a danger during lifting, making it impractical. Summary of the Invention

[0004] The purpose of this invention is to provide a hook device that can open the hook by setting a counterweight block in cooperation with the hook body, thereby realizing the automatic unloading of items, while ensuring safety. The structure is simpler and more convenient and practical.

[0005] The embodiments of the present invention are implemented as follows:

[0006] This application provides a hook device, including a boom and a hook body rotatably disposed on the boom. The top of the hook body is inclinedly provided with a counterweight block. The hook body is rotatably provided with a blocking component for blocking the opening of the hook body. A linkage component is provided between the blocking component and the boom, and the linkage component is located on one side of the hook body.

[0007] Furthermore, in some embodiments of the present invention, the aforementioned boom is provided with a first pivot, the aforementioned hook body is provided with a first through hole, and the aforementioned first pivot passes through the aforementioned first through hole.

[0008] Furthermore, in some embodiments of the present invention, the aforementioned shielding assembly includes a stop block and a connecting rod connected to each other, and the aforementioned linkage assembly includes a first linkage rod and a second linkage rod rotatably connected to each other. The end of the first linkage rod away from the second linkage rod rotatably abuts against the bottom of the aforementioned boom; the end of the second linkage rod away from the first linkage rod is connected to the aforementioned connecting rod, and the aforementioned connecting rod is rotatably connected to the aforementioned hook body.

[0009] Furthermore, in some embodiments of the present invention, a second rotating shaft is also included, the first linkage rod is provided with a second through hole, the second linkage rod is provided with a third through hole, and the second rotating shaft passes through the second through hole and the third through hole in sequence.

[0010] Furthermore, in some embodiments of the present invention, the connecting rod is provided with a third pivot, the hook body is provided with a fourth through hole, and the third pivot passes through the fourth through hole.

[0011] Furthermore, in some embodiments of the present invention, the counterweight is provided with an indicator light, the hook body is provided with a Hall switch, the indicator light is electrically connected to the Hall switch, and the stop is provided with a first magnet for cooperating with the Hall switch.

[0012] Furthermore, in some embodiments of the present invention, the counterweight is provided with a speaker for indicating that the weight has been removed, and the speaker is electrically connected to the Hall switch.

[0013] Furthermore, in some embodiments of the present invention, the aforementioned boom is provided with a lifting rope.

[0014] Furthermore, in some embodiments of the present invention, the counterweight is made of metal, and the suspension rope is provided with a second magnet for attracting the counterweight.

[0015] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects:

[0016] This application provides a hook device, including a boom and a hook body rotatably disposed on the boom. The top of the hook body is inclinedly provided with a counterweight block. The hook body is rotatably provided with a blocking component for blocking the opening of the hook body. A linkage component is provided between the blocking component and the boom, and the linkage component is located on one side of the hook body.

[0017] In actual use, by hanging an item onto the hook body, the hook body rotates around the boom under the weight of the item. The blocking component rotates along with the hook body and, under its own weight, rotates around the hook body until its end abuts against the hook body on the inward-facing side, thus blocking the opening of the hook body. Furthermore, after the blocking component is limited at the end of the hook body, it cannot rotate outwards, preventing accidents during lifting. When the item is delivered to its destination and lowered, the hook body is no longer under the weight of the item. Because of the counterweight at the top of the hook, the hook body rotates in the opposite direction around the boom under the weight of the counterweight, with the hook opening facing downwards. Simultaneously, the boom and the linkage component approach and abut, pushing the linkage component to rotate, which in turn causes the blocking component to rotate, exposing the opening of the hook body. This allows the hook body to be removed directly from the item without manual unloading, making it more convenient. This design is simple in structure, more convenient and safer, and improves overall practicality. Attached Figure Description

[0030] Example 1

[0031] Please refer to Figures 1-4 This application provides a hook device, including a boom 1 and a hook body 2 rotatably disposed on the boom 1. The top of the hook body 2 is provided with a counterweight 3 at an incline. The hook body 2 is rotatably provided with a blocking component for blocking the opening of the hook body 2. A linkage component is provided between the blocking component and the boom 1. The linkage component is located on one side of the hook body 2.

[0032] In actual use, by hanging the item on the hook body 2, the hook body 2 rotates around the boom 1 under the weight of the item. The blocking component rotates with the hook body 2 and rotates around the hook body 2 under its own weight until the end of the blocking component abuts against the hook body 2 on the side facing inward at the end of the hook body 2, thereby blocking the opening of the hook body 2. Moreover, after the blocking component is limited at the end of the hook body 2, the blocking component cannot rotate outward at the end of the hook body 2, thus preventing safety accidents when lifting items. When the item is delivered to its destination and lowered, and the hook body 2 is no longer under the weight of the item, the counterweight 3 at the top of the hook causes the hook body 2 to rotate in the opposite direction around the boom 1 under the influence of the counterweight 3. The opening of the hook body 2 then faces downwards. Simultaneously, the boom 1 approaches and abuts against the linkage component, pushing it to rotate. This, in turn, causes the shielding component to rotate, exposing the opening of the hook body 2. This allows the hook body 2 to be easily removed from the item without manual unloading, making it more convenient. This design is simple, convenient, and safe, improving overall practicality.

[0033] Example 2

[0034] Please refer to Figures 1-4 In some embodiments of the present invention, the above-mentioned boom 1 is provided with a first rotating shaft 4, the above-mentioned hook body 2 is provided with a first through hole, and the above-mentioned first rotating shaft 4 passes through the above-mentioned first through hole.

[0035] In actual use, by setting two lifting rods 1 relative to each other and setting a first rotating shaft 4 between the two lifting rods 1, the hook body 2 can rotate on the first rotating shaft 4. This design structure is simpler, easier to operate, and more practical.

[0036] Example 3

[0037] Please refer to Figures 1-4In some embodiments of the present invention, the shielding assembly includes a stop block 5 and a connecting rod 6 connected to each other, and the linkage assembly includes a first linkage rod 7 and a second linkage rod 8 rotatably connected to each other. The end of the first linkage rod 7 away from the second linkage rod 8 rotatably abuts against the bottom of the lifting rod 1; the end of the second linkage rod 8 away from the first linkage rod 7 is connected to the connecting rod 6, and the connecting rod 6 is rotatably connected to the hook body 2.

[0038] When unloading items, the boom 1 remains stationary in the vertical direction. As the hook body 2 rotates around the boom 1 under the weight of the counterweight 3, the blocking component also rotates. The angle between the boom 1 and the first linkage rod 7 increases. With the rotation of the hook body 2, the angle between them continues to increase, and the lower end of the boom 1 approaches and abuts against the end of the first linkage rod 7 to push it forward. Simultaneously, the first linkage rod 7 rotates inside the second linkage rod 8, thus reducing the angle between the first linkage rod 7 and the second linkage rod 8 to accommodate the shortening of the distance. During this process, the second linkage rod 8 drives the connecting rod 6 to rotate, causing the stop block 5 to rotate under the influence of the connecting rod 6, exposing the opening of the hook body 2. This design simplifies the structure, makes operation more convenient, and improves overall practicality.

[0039] Optionally, the first linkage rod 7 in this embodiment may be provided with a protrusion, and the hook body 2 is provided with a groove to accommodate the linkage component. Therefore, the protrusion can extend outward from the groove to abut against the bottom of the rod 1, so that when the linkage component rotates, the rod 1 can push the protrusion to make the linkage component rotate.

[0040] Optionally, in this embodiment, the connecting rod 6 may be provided with an inward crossbar that is fixedly connected to the second linkage rod 8.

[0041] Example 4

[0042] Please refer to Figures 1-4 In some embodiments of the present invention, a second rotating shaft 9 is also included. The first linkage rod 7 is provided with a second through hole, and the second linkage rod 8 is provided with a third through hole. The second rotating shaft 9 passes through the second through hole and the third through hole in sequence.

[0043] In actual use, the first linkage rod 7 and the second linkage rod 8 rotate simultaneously around the second rotating shaft 9, thereby changing the included angle between them to coordinate with the rotation of the hook body 2 around the lifting rod 1. This design structure is simpler and easier to operate, thus improving the practicality of this hook device.

[0044] Example 5

[0045] Please refer to Figures 1-4In some embodiments of the present invention, the connecting rod 6 is provided with a third rotating shaft 10, the hook body 2 is provided with a fourth through hole, and the third rotating shaft 10 passes through the fourth through hole.

[0046] By setting two connecting rods 6 relative to each other, and then setting a third rotating shaft 10 between the two connecting rods 6 and passing through the fourth through hole, the baffle can be installed on the hook body 2. Moreover, the third rotating shaft 10 can rotate relative to the hook body 2 to cooperate with the rotation of the second linkage rod 8. This design is simple in structure and more convenient and practical.

[0047] Example 6

[0048] Please refer to Figures 1-4 In some embodiments of the present invention, the counterweight 3 is provided with an indicator light 11, the hook body 2 is provided with a Hall switch 12, the indicator light 11 is electrically connected to the Hall switch 12, and the stop block 5 is provided with a first magnet 13 for cooperating with the Hall switch 12.

[0049] In actual use, when the hook body 2 and the baffle rotate to the point where the baffle contacts the first magnet 13, the Hall switch 12 is in the closed state, thus turning off the indicator light 11. When the item is unloaded, the hook body 2 and the baffle rotate to expose the opening of the hook. At this time, the Hall switch 12 separates from the first magnet 13 and is in the open state, thus illuminating the indicator light 11. In this way, the change in the state of the indicator light 11 can indicate that the unloading of the item has been completed, which is more convenient and practical.

[0050] Optionally, the indicator light 11 in this embodiment may be an LED light.

[0051] Optionally, the first magnet 13 in this embodiment can be a permanent magnet. Permanent magnets retain their magnetism for a long time, which can increase the service life.

[0052] Example 7

[0053] Please refer to Figures 1-4 In some embodiments of the present invention, the counterweight 3 is provided with a speaker 14 for indicating that the weight has been removed, and the speaker 14 is electrically connected to the Hall switch 12.

[0054] In actual use, when the hook body 2 and the baffle rotate to the point where the baffle contacts the first magnet 13, the Hall switch 12 is in the closed state, thereby turning off the speaker 14. When the item is unloaded, the hook body 2 and the baffle rotate to expose the opening of the hook. At this time, the Hall switch 12 separates from the first magnet 13 and is in the open state, thereby causing the speaker 14 to emit a sound, thus indicating that the unloading of the item has been completed, which is more convenient and practical.

[0055] Optionally, in this embodiment, the speaker 14 is located inside the counterweight 3, which protects the speaker 14 without taking up more space, and the sound can be better propagated by setting small holes.

[0056] Example 8

[0057] Please refer to Figures 1-4 In some embodiments of the present invention, the above-mentioned boom 1 is provided with a suspension rope 15.

[0058] By setting up the suspension rope 15, the flexibility of the suspension rope 15 can be used to better fix this hook device to lifting machines such as drones, making it more convenient to operate and improving the practicality of this hook device.

[0059] Optionally, the hoisting rope 15 in this embodiment can be made of nylon rope, steel wire rope, etc.

[0060] Example 9

[0061] Please refer to Figures 1-4 In some embodiments of the present invention, the counterweight 3 is made of metal, and the suspension rope 15 is provided with a second magnet 16 for attracting the counterweight 3.

[0062] By installing a second magnet 16 on the lifting rope 15, with the second magnet 16 positioned slightly higher than the counterweight 3, it is possible to suspend the item briefly by rotating the hook body 2 to the lifting position when it is fixed to the hook body 2. This is achieved through the magnetic attraction between the second magnet 16 and the counterweight 3, without requiring the item to be constantly held onto the counterweight 3. This design is more convenient and improves overall practicality.

[0063] In summary, this application provides a hook device, including a boom 1 and a hook body 2 rotatably mounted on the boom 1. A counterweight 3 is inclinedly mounted on the top of the hook body 2. A blocking component for blocking the opening of the hook body 2 is rotatably mounted on the hook body 2. A linkage component is provided between the blocking component and the boom 1, and the linkage component is located on one side of the hook body 2. In actual use, by hanging an item on the hook body 2, the hook body 2 rotates around the boom 1 under the weight of the item. The blocking component rotates with the hook body 2 and rotates around the hook body 2 under its own weight until the end of the blocking component abuts against the hook body 2 on the inward-facing side of the end of the hook body 2, thereby blocking the opening of the hook body 2. Furthermore, after the blocking component is limited at the end of the hook body 2, it cannot rotate outward from the end of the hook body 2, thus preventing safety accidents during the lifting of items. When the item is delivered to its destination and lowered, and the hook body 2 is no longer under the weight of the item, the counterweight 3 at the top of the hook causes the hook body 2 to rotate in the opposite direction around the boom 1 under the influence of the counterweight 3. The opening of the hook body 2 then faces downwards. Simultaneously, the boom 1 approaches and abuts against the linkage component, pushing it to rotate. This, in turn, causes the shielding component to rotate, exposing the opening of the hook body 2. This allows the hook body 2 to be easily removed from the item without manual unloading, making it more convenient. This design is simple, convenient, and safe, improving overall practicality.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
