[0033] See Figures 1 to 7 As shown, this utility model embodiment provides a hook, including: a mounting base 1, a first hook body 2 and a second hook body 3. One end of the first hook body 2 and the second hook body 3 are rotatably connected to the mounting base 1, and the other end of the first hook body 2 and the second hook body 3 are detachably connected.

[0034] Specifically, the first hook 2 and the second hook 3 are used to connect to the suspension frame, and the end of the mounting base 1 away from the first hook 2 and the second hook 3 is used to connect the object to be suspended. When the hooks are not in use, the first hook 2 and the second hook 3 can be adjusted relative to the mounting base 1 according to the actual situation, so that they are in an initial position that is convenient for subsequent operations. This position can vary depending on the installation location and the surrounding environment. For example, in a narrow space, the hooks can be rotated to a position close to the mounting base 1 to reduce the space occupied. When an object needs to be suspended by hooks, first connect the mounting base 1 to the object to be suspended. Then, depending on the weight of the object and the style of the hanging frame, select one or two hooks to suspend the object on the hanging frame. When using two hooks to suspend the object, first adjust the position of the first hook 2 and the second hook 3 to separate the detachable ends of the two hooks to form an opening. Then, through this opening, move the first hook 2 and the second hook 3 to both sides of the hanging frame. Afterward, close the detachable ends of the first hook 2 and the second hook 3 to form a closed structure, thus suspending the object. When it is necessary to remove the object, first loosen the detachable ends of the hooks to reopen the two hooks. After removing the object, the hooks can be returned to their initial state, ready for the next use.

[0035] In this embodiment, the mounting base 1 provides a fixed point for connecting the object. One end of the first hook 2 and the second hook 3 can be flexibly rotated and connected to the mounting base 1, facilitating adjustment of the suspension angle. The other end forms a closed structure through a detachable connection, allowing the hook to be quickly closed or opened, thus facilitating the suspension or removal of the object and enhancing the stability of the suspended object. This rotatable connection and detachable design make the hook suitable for various suspension scenarios and flexible in use. It is understood that the connection between the mounting base 1 and the object can be either a fixed connection or a detachable connection.

[0036] In one specific embodiment, the mounting base 1 is provided with a connecting part 11, and the first hook body 2 and the second hook body 3 are rotatably connected to the connecting part 11 at one end near the mounting base 1.

[0037] Specifically, the connecting part 11 on the mounting base 1 is specifically designed for the rotational connection of the first hook 2 and the second hook 3. The hook rotates around the connecting part 11, allowing the user to flexibly adjust the angles of the first hook 2 and the second hook 3 according to the shape and size of the object and the needs of the hanging frame. By connecting the end of the hook closest to the mounting base 1 to the connecting part 11, the rotation fulcrum of the hook is clearly defined, concentrating the rotational function of the entire hook in the connecting part 11. This centralized connection makes the rotational connection more robust and stable. Compared to arbitrarily rotating the hook on the mounting base 1, it can better withstand the weight of the object and external forces, reducing the risk of hook damage or connection failure due to uneven force distribution, and improving the overall service life of the hook. Furthermore, the presence of the connecting part 11 allows users to operate the rotation of the hook more intuitively and accurately, making the adjustment of the hook angle smoother and more precise. This facilitates quick adjustment of the hook position according to actual needs, improving the ease of use of the hook.

[0038] In one specific embodiment, the hook further includes a first rotating shaft 4 and a second rotating shaft 5. The connecting part 11 is provided with a first movable groove 111 and a second movable groove 112 on both sides near the first hook body 2 and the second hook body 3, respectively. The two ends of the first rotating shaft 4 are respectively connected to the first movable groove 111 and the first hook body 2; the two ends of the second rotating shaft 5 are respectively connected to the second movable groove 112 and the second hook body 3.

[0039] Specifically, by introducing a first rotating shaft 4 and a second rotating shaft 5, and connecting the two ends of the first rotating shaft 4 to the first movable groove 111 and the first hook body 2 respectively, and connecting the two ends of the second rotating shaft 5 to the second movable groove 112 and the second hook body 3 respectively, a rotational connection between the hook body and the connecting part 11 is achieved. The rotating shafts act as supports and pivots, allowing the hook body to rotate around the rotating shafts. The design of the first movable groove 111 and the second movable groove 112 provides a certain amount of space for the rotating shafts, limiting their range of motion and thus ensuring the stability and directionality of the hook body's rotation. This design allows for more standardized rotation of the hook body, avoiding hook body swaying or shaking caused by shaft misalignment, and improving the reliability of the rotational connection.

[0040] In one specific embodiment, both the first movable groove 111 and the second movable groove 112 are arranged in a fan shape, with the center of the connecting part 11 as the vertex of the fan shape.

[0041] Specifically, traditional rotating shafts typically rotate only around the center of their own radial cross-section, resulting in a relatively simple rotation method. In this embodiment, however, by designing the first movable groove 111 and the second movable groove 112 as fan-shaped with the center of the connecting part 11 as the vertex, the first rotating shaft 4 and the second rotating shaft 5 possess multiple rotation centers. On one hand, the center of the radial cross-section of the rotating shaft itself can serve as the rotation center, ensuring a certain degree of normal rotation of the hook. On the other hand, since the movable grooves are fan-shaped with the center of the connecting part 11 as the vertex, when the rotating shaft moves along the fan-shaped movable grooves, the center of the connecting part 11 can also be considered as a rotation center. This design utilizes the geometric characteristics of a fan shape, allowing the hook to perform more flexible circular motion around the center of the connecting part 11 during rotation. This multi-rotation-center design principle enables more diverse hook movement trajectories, meeting the suspension requirements of different angles and positions. Because different rotation centers can provide different rotation radii and ranges for the hook, the hook can be adjusted more flexibly according to the specifications of the object when suspending it, improving the hook's flexibility and adaptability.

[0042] In one specific embodiment, the center of the connecting part 11 is provided with a circular groove 113, and the hook also includes a rotating center part 6, which is rotatably connected to the circular groove 113. The first rotating shaft 4 passes through the first movable groove 111 and is connected to the rotating center part 6, and the second rotating shaft 5 passes through the second movable groove 112 and is connected to the rotating center part 6.

[0043] Specifically, the rotating center 6 is circular, and its outer periphery abuts against the circular groove 113. The circular groove 113 at the center of the connecting part 11, along with the circular rotating center 6, is designed to create a centralized rotating structure. The circular groove 113 provides a precise rotational track for the rotating center 6, and the rotating center 6, as the core rotating component, ensures its rotational stability and directionality by abutting against the circular groove 113. The first rotating shaft 4 and the second rotating shaft 5 pass through the first movable groove 111 and the second movable groove 112, respectively, and are connected to the rotating center 6, forming a chain-like transmission structure. When the rotating center 6 rotates, it drives the first rotating shaft 4 and the second rotating shaft 5, thereby enabling the first hook body 2 and the second hook body 3 to rotate synchronously. The design of the circular rotating center 6 and the circular groove 113 utilizes the geometric characteristics of a circle, ensuring smooth and uniform rotation. Since the distance from any point on the circumference of a circle to the center is equal, the contact force between the rotating center part 6 and the circular groove 113 is more uniform during rotation, reducing the risk of component wear or structural damage caused by excessive local force.

[0044] In one specific embodiment, an angle is formed between the first rotating shaft 4 and the second rotating shaft 5.

[0045] Specifically, when an angle is formed between the first rotating shaft 4 and the second rotating shaft 5, it means that the rotation directions of the first hook 2 and the second hook 3 relative to the connecting part 11 are no longer parallel. This design aims to provide more diverse suspension angle and suspension space adjustment methods. Due to the presence of the angle, the first hook 2 and the second hook 3 can unfold on different planes or at different angles, better adapting to the complexity of the object's shape and spatial layout. By adjusting the size of the angle, the relative positional relationship between the hooks can be changed to meet the suspension angle requirements of objects of different shapes and sizes, providing more flexible suspension conditions for the objects.

[0046] Furthermore, the included angle is 180 degrees.

[0047] When the angle between the first rotating shaft 4 and the second rotating shaft 5 is 180 degrees, the first hook 2 and the second hook 3 are in relative positions, presenting a linear suspension structure. This structure allows the first hook 2 and the second hook 3 to evenly distribute the weight of the object, symmetrically distributing the object's gravity along the two hooks, reducing the force on individual hooks, and improving the stability and load-bearing capacity of the suspension. It is understood that in other embodiments, the angle can be set to other values ​​depending on the actual application scenario.

[0048] Furthermore, the first rotating shaft 4 and the second rotating shaft 5 are integrally formed. Designing the first rotating shaft 4 and the second rotating shaft 5 as an integral structure aims to enhance the overall integrity and strength of the structure. Integral forming eliminates potential weaknesses in traditional connection methods (such as welding and bolting), making the entire rotating structure a continuous whole and improving the mechanical properties of the components. From a manufacturing perspective, integral forming reduces the number of parts, simplifies the production process, reduces assembly errors that may arise from assembling multiple parts, and improves production efficiency and product quality consistency. Simultaneously, because it is a single unit, when subjected to external forces, the force can be transmitted more evenly throughout the structure, avoiding stress concentration points between different components and improving the reliability of the structure.

[0049] In one specific embodiment, the mounting base 1 is also provided with a protective part 12 near the end of the hook. The protective part 12 is located on the outer periphery of the connecting part 11, and a mounting groove 13 is formed between the outer periphery of the connecting part 11 and the inner periphery of the protective part 12. The first hook body 2 and the second hook body 3 are both rotatably connected to the mounting groove 13.

[0050] Specifically, when the hooks are not in use, the first hook 2 and the second hook 3 rotate until both are fully contained within the mounting groove 13. The protective part 12 and the connecting part 11 together define the range of the mounting groove 13, providing a suitable storage space for the hooks. This allows the hooks to remain neat and compact when not in use, avoiding space waste and potential safety hazards caused by exposed hooks, and facilitating storage and organization. For storage or display equipment, this storage function helps improve space utilization efficiency and makes the entire system look more organized. The first hook 2 and the second hook 3 are rotatably connected to the mounting groove 13, allowing them to rotate within the groove while being confined within this space. The protective part 12, as the outer boundary of the mounting groove 13, protects the hooks, preventing them from falling off the mounting base 1 due to external force, accidental collision, or improper operation during rotation or use. This design combines the storage and protection functions of the hook. Through the structural cooperation of the protective part 12 and the connecting part 11, it ensures that the hook is in a relatively safe position in both normal and non-use states, thereby improving the safety and reliability of the hook.

[0051] In one specific embodiment, the first hook 2 is engaged with the second hook 3.

[0052] Specifically, by designing the detachable connection between the first hook body 2 and the second hook body 3 as a snap-fit, users can quickly close or open the first hook body 2 and the second hook body 3 when using the hook, without the need for tools. This improves the convenience and efficiency of using the hook, making it easier to hang and remove objects. This design allows for quick closing and opening, making it suitable for scenarios requiring frequent hook use. Furthermore, when the first hook body 2 and the second hook body 3 are snapped together, they form a relatively sturdy whole, providing more stable support for the object and preventing the hook from slipping off the hanging position. Especially for larger or heavier objects, the snap-fit ​​structure ensures the stability and reliability of the hook.

[0053] It is understood that in other embodiments, the detachable connection between the first hook body 2 and the second hook body 3 may also be achieved by means of bolt connection or other similar methods.

[0054] In one specific embodiment, the first hook body 2 includes a fixed part 21 and a rotating rod 22; the fixed part 21 is connected to the first rotating shaft 4; one end of the rotating rod 22 is rotatably connected to the fixed part 21, and the other end is engaged with the second hook body 3.

[0055] Specifically, the first hook 2 is divided into a fixed part 21 and a rotating rod 22. The fixed part 21 is connected to the first rotating shaft 4, allowing the first hook 2 to rotate as a whole with the first rotating shaft 4 as support, ensuring the overall rotation function of the hook. One end of the rotating rod 22 is rotatably connected to the fixed part 21, and the other end is engaged with the second hook 3. This design provides additional flexibility to the first hook 2. The rotatable connection of the rotating rod 22 allows it to have a certain degree of rotational freedom relative to the fixed part 21. When it is necessary to open or close the hook, the angle of the rotating rod 22 can be directly adjusted, facilitating the opening and closing operation of the hook.

[0056] Furthermore, the fixed part 21 and the rotating rod 22 are rotatably connected by a pivot pin 23, which has a simple structure, is easy to manufacture and install, and has a low cost.

[0057] It is understood that in other embodiments, the rotational connection between the fixed part 21 and the rotating rod 22 can also be achieved by other solutions such as hinges and bearings.

[0058] In one specific embodiment, the rotating rod 22 is provided with a first engaging protrusion 221 at one end near the second hook body 3, and the second hook body 3 is provided with a first engaging groove 31 at one end near the rotating rod 22, and the first engaging protrusion 221 engages with the first engaging groove 31.

[0059] Specifically, the rotating rod 22 has a first abutting surface 222 at one end near the second hook 3, and the first abutting surface 222 faces away from the connecting part 11. The second hook 3 has a second abutting surface 32 at one end near the rotating rod 22, and the second abutting surface 32 faces the connecting part 11. A first engaging protrusion 221 protrudes from the first abutting surface 222, and a first engaging groove 31 is recessed into the second abutting surface 32. When the first hook 2 is engaged with the second hook 3, the first abutting surface 222 abuts against the second abutting surface 32, and the first engaging protrusion 221 engages with the first engaging groove 31.

[0060] The design of the first engaging protrusion 221 and the first engaging groove 31 is to achieve the engaging function between the rotating rod 22 and the second hook body 3. By inserting the first engaging protrusion 221 into the first engaging groove 31, the shapes of the two fit together, allowing the rotating rod 22 and the second hook body 3 to be firmly connected together, forming the closed state of the hook. The first abutting surface 222 and the second abutting surface 32 are designed to ensure that there is a planar abutment between the rotating rod 22 and the second hook body 3 during engagement, increasing the stability and reliability of the engagement. When the first engaging protrusion 221 engages with the first engaging groove 31, the abutment between the first abutting surface 222 and the second abutting surface 32 makes the contact between the two more compact, so that when bearing the weight of an object, the force can be better distributed on the abutting surface, improving the load-bearing capacity of the hook. The first engaging protrusion 221 protrudes from the first abutting surface 222, and the first engaging groove 31 is recessed into the second abutting surface 32. This concave-convex design ensures that the first engaging protrusion 221 can accurately enter the first engaging groove 31 during engagement. Furthermore, in the vertical direction, the cooperation of the abutting surfaces prevents the hook from accidentally disengaging due to external force or vibration during use. In addition, this engagement structure is relatively simple. During operation, the user only needs to rotate the rotating rod 22 toward the second hook body 3 or pull it away from the second hook body 3 to complete the engagement or disengagement operation, without complicated operating steps or tools, thus improving the convenience and efficiency of hook use.

[0061] In one specific embodiment, both the first abutting surface 222 and the second abutting surface 32 are S-shaped.

[0062] Specifically, the first contact surface 222 and the second contact surface 32 are designed in an S-shape, primarily to increase the contact area and friction. The S-shaped surface has an undulating shape; compared to a flat contact surface, different parts of the S-shaped contact surface will contact sequentially during engagement, forming multiple contact points or areas, increasing friction and improving engagement stability. From a mechanical perspective, the S-shaped contact surface allows for a more even distribution of force on the contact surface. When the hook bears the weight of an object, because the contact surface is not a simple planar contact, the force can be dispersed and transmitted along the S-shaped curve, avoiding stress concentration in certain local areas and improving the overall load-bearing capacity of the hook structure. Furthermore, the S-shaped contact surface also provides a certain degree of anti-detachment effect. Due to its special shape, it can generate a certain degree of resistance when subjected to external force, preventing the rotating rod 22 and the second hook body 3 from easily disengaging due to external force, thus increasing the reliability of the engagement structure.

[0063] In one specific embodiment, a mounting and positioning groove (not shown in the figure) is formed on the side of the rotating rod 22 near the connecting part 11.

[0064] Specifically, when the hook is connected to the suspension frame, the top of the suspension frame abuts against the hook positioning groove. The cooperation between the hook positioning groove and the suspension frame effectively prevents the hook from shifting or swaying during use, ensuring that the hook maintains a stable position under various environmental and stress conditions, providing reliable support for objects and improving the stability of the entire suspension system. For scenarios requiring stable suspension, such as in warehousing, shelf display, or industrial suspension, it ensures that the hook will not change position due to external factors, preventing objects from falling or being damaged. Furthermore, the reaction force of the suspension frame on the rotating rod 22 ensures that the first locking protrusion 221 stably engages with the first locking groove 31, reducing the possibility of the rotating rod 22 disengaging from the second hook body 3 due to hook swaying or accidental movement of objects, thus guaranteeing the reliability of the hook during long-term use.

[0065] In one specific embodiment, the rotating rod 22 is provided with a second snap-fit ​​protrusion 223 on the side near the connecting part 11, and the second hook body 3 is provided with a corresponding second snap-fit ​​groove 33.

[0066] Specifically, when the first engaging protrusion 221 engages with the first engaging groove 31, the second engaging protrusion 223 also engages with the second engaging groove 33. This double engaging structure increases the connection strength between the rotating rod 22 and the second hook body 3, reduces the possibility of loosening at the engagement point due to external force or vibration, and improves the overall stability of the hook. This double engaging structure can withstand greater external force and weight, making it suitable for heavier applications or scenarios requiring long-term stable suspension.

[0067] More specifically, the rotating rod 22 has a recessed surface 224 on the side near the connecting part 11. The second snap-fit ​​protrusion 223 is J-shaped, with one end connected to the recessed surface 224 and facing the second snap-fit ​​groove 33, and the other end facing the connecting part 11, so that the second snap-fit ​​protrusion 223 and the recessed surface 224 combine to form a hook-and-mount positioning groove. By setting the second snap-fit ​​protrusion 223 to a J-shape and having one end connected to the recessed surface 224, the combination of the J-shaped protrusion and the recessed surface 224 cleverly utilizes the hook-and-mount positioning groove, which is a multi-functional structural design. The shape matching of the recessed surface 224 and the J-shaped protrusion provides additional snap-fit ​​functionality and utilizes their combined space to form a hook-and-mount positioning groove, improving space utilization and structural versatility. The hook-and-mount positioning groove formed by the J-shaped protrusion and the recessed surface 224 utilizes its special shape, allowing the suspension bracket to be connected to the hook in a specific manner. The recessed surface 224 can provide a certain amount of space for the suspension bracket, while the J-shaped protrusion can limit the suspension bracket and prevent it from easily coming out of the mounting and positioning groove.

[0068] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
