Description

[0001] The present invention relates to a hook structure, in particular to a rotatable hook mechanism with balance support function and monitoring function, which can be used in industrial equipment, machinery, electronic equipment or measuring systems that require suspension and monitoring.

[0002] Traditional hook designs often use simple mechanical structures such as hooks or chains to suspend objects. While simple in design, such designs lack flexibility for adjustment and no ability to monitor the suspension status in real time, which can pose safety risks if the balance is incorrect.

[0003] Existing rotating hook mechanisms are typically based on purely mechanical structures and lack real-time balance support functions. Due to the lack of precise monitoring mechanisms, users have difficulty assessing the actual suspension status, which can lead to instability or tilting, compromising operational safety. Traditional hooks are usually rigid and offer limited adjustment and expansion options.

[0004] While hook-based systems with monitoring capabilities are available on the market, they are often complex, difficult to install, and expensive. Such systems often require skilled personnel to operate and maintain, increasing operating costs. Furthermore, many of these systems lack intelligent functionality, limiting their adaptability to different operating environments and requirements.

[0005] The market therefore urgently needs a simple, user-friendly, and cost-effective hook design that offers balance support and vibration dampening functions and is flexibly adaptable. The present invention aims to solve these problems by providing a rotating hook mechanism with a balance support function that enables stable suspensions, has a robust structure, and integrates vibration absorption. An angle sensor, a controller, and a drive enable automatic balance adjustment when a predetermined rotation angle is exceeded.

[0006] The aim of the present invention is to provide a rotating hook mechanism with a balance support function that can be installed directly on a ceiling or underneath an object. The invention features a simple structure, easy assembly, and real-time monitoring functions, making it versatile.

[0007] The present invention relates to a rotatable hook mechanism with balance support function, comprising a first hook having an upper link and a lower link, a second hook detachably attached to the lower link of the first hook, a third hook rotatably mounted on the second hook, and an eyebolt disposed at a lower end of the third hook. The second hook has an open hook portion detachably attached to the lower link of the first hook, and an axle hole disposed at a lower end of the second hook. The third hook is provided with an axle portion inserted into the axle hole of the second hook, so that the third hook is rotatable relative to the second hook.

[0008] In one embodiment, the invention additionally comprises an angle sensor arranged between the second and third hooks to detect the angle of rotation of the third hook relative to the second hook and generate an angle signal. Furthermore, the invention comprises a balance support mechanism comprising a drive installed between the second and third hooks and a controller electrically connected to the angle sensor and the drive. The controller controls the drive based on the angle signal generated by the angle sensor, so that when a preset angle of rotation is exceeded, the angle of rotation of the third hook relative to the second hook is automatically adjusted.

[0009] In a further embodiment, the upper connecting element of the first hook serves as a rotation axis, which is rotatably connected to a telescopic rod, so that a flexible adjustment of the position of the hook to different application scenarios is possible.

[0010] In a preferred embodiment, both the first hook and the third hook are equipped with a safety lock that ensures the safety of the suspension and prevents accidental release of the hooks during operation.

[0011] In addition, the mechanism includes an elastic ring mounted in the axle hole of the second hook to effectively absorb vibrations caused by the rotational movement of the third hook relative to the second hook, thus increasing the stability of the entire suspension device.

[0012] The mechanism's eyebolt is designed to be connected to a weight sensor to enable precise collection of weight data of the attached object and to provide this data for further processing steps.

[0013] The weight sensor is electrically connected to a control module, which includes a display unit for displaying the recorded weight data and a memory unit for storing this data, enabling real-time monitoring and subsequent analysis of the weight history of the attached object. The weight sensor is electrically connected to a control module, which includes a display unit for displaying the recorded weight data and a memory unit for storing this data, enabling real-time monitoring and subsequent analysis of the weight history of the attached object.

[0014] In a further embodiment, a fastening screw is provided which connects the weight sensor to a weighing pan, thereby ensuring a stable and precise measurement of the weight changes of the attached object.

[0015] Between the second hook and the third hook there is a limiting structure which restricts the maximum angle of rotation of the third hook relative to the second hook in order to prevent uncontrolled rotation and increase the safety and stability of the mechanism.

[0016] The surfaces of the first hook, second hook, third hook, and eyebolt are coated with a corrosion-resistant layer made of stainless steel, galvanized material, or a corrosion-resistant coating. Additionally, a dirt-repellent layer is present, which has hydrophobic properties and allows for easy cleaning of the surface, thus extending the service life of the mechanism and ensuring wide application in various environments.

[0017] With the structure described above, the rotary hook mechanism with balance support function according to the present invention offers the following advantages: 1. The construction is simple and the installation is convenient; 2. The mechanism has a balance assistance function that automatically adjusts the rotation angle according to the inclination; 3. A vibration damping function improves stability during use; 4. The surface is corrosion and dirt resistant, which extends the service life; 5. The mechanism is versatile and offers high flexibility in different application areas.

[0020] In order to more clearly describe the present invention of a rotary hook mechanism with balance support function, preferred embodiments will be explained in detail below with reference to the drawings.

[0021] Referring to the Fig. 1 and Fig. 2 shows Fig. 1 is a schematic view of an assembled rotary hook mechanism 1 according to the invention, while Fig. 2 is an exploded view of the same. As shown in the figures, the rotatable hook mechanism 1 comprises a first hook 10, a second hook 20, a third hook 30, and an eyebolt 40. The first hook 10 has an upper connecting element 11 and a lower connecting element 12, wherein a safety lock 13 with an on / off function is provided. The second hook 20 has an open hook part 21 and an axle opening 22, wherein the open hook part 21 is detachably attached to the lower connecting element 12 of the first hook 10 by switching the safety lock 13 on and off. The axle opening 22 is located at the lower end of the second hook 20. The third hook 30 is provided at the upper end with an axle part 31 which is rotatably inserted into the axle opening 22 of the second hook 20, so that the third hook 30 is rotatable relative to the second hook 20.Another safety lock 32 is located on the third hook 30, and the eyebolt 40 can be removably attached to the lower end of the third hook 30 by switching the safety lock 32 on and off.

[0022] The first hook 10 and the second hook 20 can both be rotated around the Z-axis, allowing any torsional moments that occur to be compensated. The second hook 20 and the third hook 30 together form a hook assembly. The eyebolt 40 can be rotated not only around the Z-axis but also around a horizontal axis in another application. Furthermore, the second hook 20 and the third hook 30 can be used with or without the eyebolt 40.

[0023] As in Fig. 3, the eyebolt 40 of the rotating hook mechanism 1 is used for connection to a weight sensor 50, the other end of which is connected to a fastening screw 60. As shown in Fig. As shown in Figure 4, the upper connecting element 11 of the first hook 10 can be configured as a pivot axis that is rotatably connected to a connecting piece 71 of the telescopic rod 70. The telescopic rod 70 allows the height position of the rotatable hook mechanism 1 to be adjusted to accommodate different poultry body sizes and enable accurate weighing operations.

[0024] The connecting piece 71 of the telescopic rod consists of a base plate unit, a lower pivot unit, and an upper pivot unit. The base plate unit includes a first base plate, a first side wall, a second side wall, a third side wall, and a fourth side wall, with the first base plate having four side edges. The first side wall is attached to the underside of the first base plate and connected to the first side edge of the base plate, with a first hole provided therein.

[0025] The lower pivot unit consists of a second base plate, a fifth side wall, and a sixth side wall. The second base plate is connected to the fifth side wall at its top. The fifth side wall has a fifth hole, and the sixth side wall, located on the opposite side of the second base plate, is equipped with a sixth hole.

[0026] The upper pivot unit consists of a third base plate, a seventh side wall, and an eighth side wall. The seventh side wall, located at the bottom of the third base plate, has a seventh hole, while the opposite eighth side wall has an eighth hole.

[0027] The first hook 10 is mounted between the second hook 20 and the connecting piece 71 of the telescopic rod.

[0028] In some embodiments, the telescopic pole connector 71 may include a universal ball joint that allows movement along multiple axes, thereby minimizing fluctuations due to poultry movement or wind.

[0029] In some embodiments, the connecting piece of the telescopic rod 71 can be configured as a ball joint, allowing movement in any direction. The ball joint allows for multiple axes of rotation and can help minimize swaying caused by bird jumps or wind turbulence.

[0030] In another embodiment, the rotatable suspension unit 14 consists of the second hook 20, the third hook 30, and the eyebolt 40, wherein the eyebolt 40 includes a third screw 14R3. The third screw 14R3 is designed to be screwed into a second threaded hole of the weight sensor 50.

[0031] On the other hand, the eyebolt 40 is connected to the third hook 30 and is thus supported by it.

[0032] The weight sensor 50 is specifically designed to have a first and a second threaded hole on its bottom and top respectively.

[0033] In addition, the fastening screw 60 is equipped with a first screw 13R1 on its underside.

[0034] With reference to Fig. 5, the eyebolt 40 of the rotating hook mechanism 1 connects the weight sensor 50, which in turn is connected to a weighing pan 80 by a fastening screw 60. A limiting structure (not shown in the drawing) can be provided between the second hook 20 and the third hook 30 to limit the angle of rotation of the third hook 30 relative to the second hook 20. The third hook 30 can rotate relative to the second hook 20, while the second hook 20 is rotatable relative to the first hook 10 through its open hook part 21. The first hook 10 can be rotated relative to the connecting piece of the telescopic rod 71 of the telescopic rod 70 via the rotation axis of its upper connecting element 11.

[0035] In a poultry farm application, the weighing pan 80 serves to hold poultry. When the poultry is standing on the weighing pan 80, the relative rotation of the hooks and the angle limitation provided by the limiting structure enable a balance-supporting function of the rotating hook mechanism 1, ensuring stable weight determination of the poultry. The connecting piece of the telescopic rod 71 connects the upper connecting element 11 of the first hook 10, allowing the height of the rotating hook mechanism 1 to be adjusted to meet the requirements of different areas of the poultry farm.

[0036] The weighing pan 80 can consist of an upper and a lower plate connected by support components. The plates can be round, oval, triangular, square, rectangular, pentagonal, or hexagonal. The radius of the upper and lower plates can range from 10 cm to 50 cm, while the distance between the plates can vary from 30 cm to 400 cm. The length of the telescopic rod 70 can range from 40 cm to 6 m.

[0037] As in Fig. Figure 6 shows a block diagram of one embodiment of the rotary hook mechanism with balance assist function according to the present invention. The rotary hook mechanism 1 may further include an angle sensor 90 and a balance assist mechanism 100. The angle sensor 90 is arranged between the second hook 20 and the third hook 30 and serves to measure the angle of rotation of the third hook 30 relative to the second hook 20 and generate an angle signal A. The balance assist mechanism 100 includes a controller 101 arranged on the second hook 20 and a driver 102 positioned between the second hook 20 and the third hook 30. The controller 101 is electrically connected to the angle sensor 90 and the driver 102 and controls the driver 102 based on the angle signal A generated by the angle sensor 90.If the measured angle of rotation exceeds a preset value, the controller 101 automatically adjusts the angle of rotation of the third hook 30 relative to the second hook 20 through the drive 102.

[0038] As in Fig. Figure 7 shows a block diagram of another embodiment of the rotary hook mechanism with balance support function. The weight sensor 50 can be used to measure the weight of poultry and generate a weight data signal W. This weight data signal W is transmitted to a control module 110 arranged on the weighing pan 80. The control module 110 includes a display unit 111 and a storage unit 112, wherein the display unit 111 is used to display the weight data signal W in real time, and the storage unit 112 is used to store these weight data signals W. This allows managers in poultry farms to observe and document the growth of the animals directly on site.

[0039] Additionally, an elastic ring (not shown in the drawings) may be integrated into the axle hole 22 of the second hook 20 to absorb the vibrations generated when the third hook 30 rotates relative to the second hook 20. This design further improves the stability and accuracy of poultry weight measurement.

[0040] Since the present invention is primarily used in poultry farms, to extend service life and ensure hygienic safety, the surfaces of the first hook 10, the second hook 20, the third hook 30, and the eyebolt 40 can be additionally coated with an anti-corrosive and anti-dirt coating. The anti-corrosive coating can be made of stainless steel, galvanized material, or corrosion-resistant coatings to protect the metal structure from the humid and ammonia-containing environment in poultry farms. The coatings can include chromium, nickel, or copper plating, or chemically applied nickel and composite coatings to ensure improved corrosion resistance.The anti-corrosion layer applied to the anti-corrosion layer can be made of hydrophobic materials such as polytetrafluoroethylene (PTFE) or polysiloxanes, which exhibit excellent hydrophobic and anti-corrosion properties. This prevents poultry droppings and other contaminants from adhering, and facilitates daily cleaning and disinfection. These layers enable easy maintenance and extend the service life of the equipment, providing economic benefits.
