Description
TECHNICAL AREA
[0001] The present utility model relates to the technical field of suspending objects, in particular to a lightweight and robust hook. TECHNICAL BACKGROUND
[0002] As society develops, people's needs for hooks become increasingly diverse, requiring not only basic hanging functions but also higher standards for installation methods, load-bearing capacity, aesthetics, and other aspects. The development of hooks has also undergone an evolutionary process, progressing from simple to complex and from a single function to multiple functions.
[0003] Currently, hooks have a relatively high weight of their own, and the adhesive layer must support this weight as well as the weight of the hung objects over the long term. The hook's own weight represents a constant static load, keeping the adhesive layer under continuous tension. With prolonged use, especially in environments with high temperatures, high humidity, or significant temperature fluctuations, the adhesive material tends to creep and fatigue due to the constant exposure to high static loads, leading to a gradual decrease in adhesive strength. Eventually, the hook may slowly slip off the wall, bulge at the edges, or even suddenly fall off, which not only impairs normal use but can also damage the hung objects or create safety hazards.
[0004] Therefore, there is an urgent need for a new hook. CONTENT OF THE PRESENT APPLICATION
[0005] The present utility model proposes a lightweight and robust hook to solve the problem that hooks in the prior art tend to fall off the wall easily due to their relatively high weight.
[0006] The technical solution of the present utility model is as follows: A lightweight and robust hook, comprehensive: a base plate that has a front and a back; a connecting rod attached to the front, wherein one longitudinal direction of the connecting rod runs perpendicular to the front; a hook head welded to one end of the connecting rod, which interacts with the connecting rod to suspend an external object; and a weight reduction hole formed on the rear side, the weight reduction hole extending to the end of the connecting rod.
[0007] The above technical solution enables a weight-reducing redesign of the main structure of the hook by forming a weight-reducing hole on the back of the base plate that extends to the end of the connecting rod.
[0008] This weight-reduction hole effectively reduces the hook's material consumption and significantly lowers its overall weight without substantially weakening the bending strength of the connecting rod or the structural strength at the junction between the base plate and the connecting rod. Due to the reduced weight of the hook, the static load that the adhesive layer must bear in the long term is correspondingly reduced. This fundamentally alleviates the creep and fatigue problems of the adhesive layer caused by sustained high static loads and significantly delays the process of adhesive strength degradation.Ultimately, during long-term use, the hook is less likely to slowly slip off the wall, bulge at the edges, or suddenly fall off, substantially improving the robustness and reliability of the connection and successfully solving the prior art technical problem of the adhesive layer being prone to fatigue due to the high weight of the hook, resulting in poor connection robustness.
[0009] Another technical solution is that the base plate has a rectangular shape and its four corners are each rounded.
[0010] The above technical solution, with its rounded design of the four corners of the base plate, prevents sharp corners or edges from scratching users or surrounding objects, thus significantly improving the product's safety, especially in high-traffic areas or children's rooms. At the same time, the rounded design gives the product a more polished and aesthetically pleasing appearance and enhances its overall texture.
[0011] As a further technical solution, it is provided that the connecting rod has a rectangular cross-section, with four corners of the connecting rod being rounded.
[0012] The above technical solution results in a connecting rod with a rectangular cross-section. Compared to a round rod, the rectangular rod offers better bending strength and can withstand greater torque or lateral force, thus preventing the hook from twisting during use. At the same time, rounding the four corners not only prevents hand injuries but also allows the lines of the rod body to flow more smoothly, achieving both structural strength and safety.
[0013] As a further technical solution, it is provided that the angle formed by the top of the hook head and the top of the connecting rod is between 120° and 150°.
[0014] The above technical solution limits the angle between the hook head and the connecting rod to between 120° and 150°. This angle not only ensures smooth insertion of an object but also, through an appropriate upward angle, provides a degree of restraint for the suspended object. This effectively prevents the object from slipping off the front of the hook head if it is accidentally touched or shaken, thus achieving both ease of use and reliable protection against falls. As a further technical solution, a distance of 20 cm to 30 cm is provided between the center of the hook head and the front of the base plate.
[0015] The above technical solution, by setting an overhang distance of 20 cm to 30 cm, ensures that there is sufficient space between the hook head and the wall to accommodate objects of larger volume or thickness, thus preventing crushing or soiling from direct contact between objects and the wall, solving the problem that conventional short hooks cannot hang large objects, and expanding the hook's range of applications.
[0016] As a further technical solution, it is planned that a connection point between the connecting rod and the base plate is located below the center of the base plate.
[0017] The above technical solution optimizes the hook's mechanical load distribution by positioning the connecting rod slightly below the center of the base plate. When objects are hung, the line of action of gravity is closer to the center of the base plate, resulting in a more even load distribution across the contact area between the base plate and the wall and reducing the tendency for the top edge to detach. This design, combined with the overall weight reduction achieved through the weight-reduction hole, works together to optimize the load distribution on the adhesive layer. The weight reduction decreases the overall load, while the lower connection improves stress distribution. These two factors complement each other, further enhancing the hook's resistance to edge warping and detachment during long-term use.
[0018] As a further technical solution, it is planned that the head part of the hook head will have the shape of a semi-circular disc.
[0019] The technical solution described above features a hemispherical disc-shaped head on the hook, significantly increasing the contact area with suspended objects (such as shopping bags with handles, towels, etc.). For a given weight, this increased contact area effectively reduces the pressure at the point of contact between the object and the hook head, protecting the suspended items from indentation or damage. This user-friendly design detail, combined with the overall lightweight construction achieved through the weight-reducing hole, allows the hook to be both light and robust, while simultaneously prioritizing the protection of the user's belongings, thus improving the overall quality of the product.
[0020] Another technical solution is to connect the hook head and the end of the connecting rod by welding.
[0021] The above technical solution, by using welding to connect the hook head to the connecting rod, creates an integral connection compared to detachable connections such as threaded or snap-fit connections. This eliminates gaps and relative movement at the joint and allows it to withstand greater shear and tensile forces, thus ensuring structural strength when suspending heavy objects. Assuming a lightweight design is achieved through the weight-reducing hole, the welded connection ensures the reliability of critical load-bearing points and eliminates the safety risk of loosening or breakage at the joint, thus achieving both lightweight construction and high strength.
[0022] The advantageous effects of the lightweight and robust hook provided by the present utility model include at least the following: 1. The present utility model enables a weight-reducing redesign of the main structure of the hook by forming a weight-reduction hole, extending to the end of the connecting rod, on the back of the base plate. This weight-reduction hole effectively reduces the material consumption of the hook and significantly lowers the overall weight of the hook without substantially weakening the bending strength of the connecting rod or the structural strength at the connection point between the base plate and the connecting rod.The hook's own weight, as a permanent static load that the adhesive layer must bear over the long term, directly reduces the detachment stress acting on the adhesive layer. This fundamentally alleviates the creep and fatigue problems of the adhesive layer caused by the continuous absorption of large static loads and significantly delays the process of adhesive strength loss. Ultimately, during long-term use, the hook is less prone to slowly slipping off the wall, bulging at the edges, or suddenly detaching. The robustness and reliability of the connection are substantially improved, thus successfully solving the prior art problem of the adhesive layer being susceptible to fatigue and exhibiting poor connection robustness due to the hook's high weight. 2. In the present utility model, the overall strength of the hook is ensured by a multiply structurally optimized design, while achieving a lightweight construction. The connecting rod is designed with a rectangular cross-section, which, compared to conventional round rods, has a higher bending coefficient and can withstand greater bending moments and lateral forces, effectively preventing the hook from twisting or bending during use. The hook head and the connecting rod are joined by welding, creating an integral combination of the two with no gap or relative movement at the joint. This allows the hook to withstand greater shear and tensile forces, thus ensuring structural strength when suspending heavy objects.These structural reinforcement measures create a synergistic effect with the lightweight construction achieved through the weight reduction hole: Even though the weight reduction hole significantly reduces material, the rectangular cross-section and the welded connection still ensure sufficient structural strength, so that the hook retains excellent load-bearing capacity despite the significant reduction in overall weight, thus truly achieving the technical breakthrough of "weight reduction without loss of strength". 3. By positioning the connection point between the connecting rod and the base plate below the center of the base plate, the entire mechanical load model of the hook is optimized in the present utility model. When hanging objects, the line of action of the objects' gravity lies closer to the central area of the base plate, so that the contact surface between the base plate and the wall is subjected to a more even load and the tendency to detach at the upper edge is effectively reduced.This design, combined with the overall weight reduction achieved through the weight reduction hole, works together to optimize the load distribution of the adhesive layer – the weight reduction decreases the overall load, while the deeper connection improves the stress distribution, with the two factors complementing each other and forming a dual technical path of “relief + force balance” that significantly reduces the risk of edge warping caused by local stress concentration, thereby creating a long-lasting stable adhesive system and further improving the hook's resistance to falling off during long-term use. 4. Based on every detail of the product design, this utility model establishes a multi-dimensional safety system as well as a user-friendly system. The four corners of the base plate and the connecting rod are each rounded, eliminating the risk of scratches that could be caused by sharp edges, especially when used in areas with frequent human activity or in children's rooms, thus significantly improving the product's safety. The top of the hook head and the top of the connecting rod form an angle of 120° to 150°, achieving a balance between hanging comfort and preventing objects from falling. This ensures smooth insertion of objects while simultaneously providing an effective upward restraint to prevent slippage.The distance between the center of the hook head and the front of the base plate is set to 20 to 30 cm, providing ample hanging space and accommodating large or thick objects. Thanks to the weight-reducing design, a long overhang no longer poses a significant risk of falling. The hook head is shaped like a semi-circular disc, increasing the contact area with the suspended items and effectively protecting them from indentation or damage. These design details make the product not only lightweight and robust but also safer, more aesthetically pleasing, and more practical, enabling it to meet diverse hanging needs in various scenarios such as behind doors, in bathrooms, bedrooms, kitchens, and more, thus offering broad market application potential.

[0024] The technical solutions in the embodiments of this utility model are described clearly and completely below in conjunction with the figures of this utility model. Obviously, the described embodiments are only a subset of the embodiments of this utility model and do not encompass all embodiments. All other embodiments that a person skilled in the art could achieve without inventive step based on the embodiments in this utility model are within the scope of protection of this utility model.
[0025] With reference to Fig. 1, Fig. 2 to Fig.3 comprises a lightweight and robust hook, provided by embodiments of the present application, a base plate 1, a connecting rod 2, a hook head 3 and a weight-reduction hole 4, wherein the connecting rod 2 is attached to the front of the base plate 1, the longitudinal direction being perpendicular to the front, wherein the hook head 3 is welded to one end of the connecting rod 2 and interacts with the connecting rod 2 to suspend an external object, wherein the weight-reduction hole 4 is formed on the rear of the base plate 1 and extends to the end of the connecting rod 2, which has the effect of reducing the weight of the hook while ensuring the strength of the hook and improving the robustness of the connection.This is because the weight reduction hole 4 reduces the overall weight of the hook, decreasing the pressure on the connection point, while a suitable structural layout improves the connection stability between the different components.
[0026] Specifically, the base plate 1 has a front and a back, and is rectangular with rounded four corners. This rectangular design provides a larger contact area between the base plate 1 and the mounting surface, thus improving mounting stability. The rounded corners prevent sharp edges from damaging surrounding objects or injuring people. The base plate 1 can be made of metal, such as stainless steel or aluminum alloy; alternatively, it can be made of high-strength plastic to suit different operating environments and load-bearing requirements.
[0027] Connecting rod 2 is attached to the front of base plate 1 and has a rectangular cross-section with rounded four corners. A rectangular cross-section better withstands forces from various directions, thus increasing the strength of connecting rod 2. Rounded corners also help prevent scratches. The connection point between connecting rod 2 and base plate 1 is located below the center of base plate 1. This layout provides a more stable center of gravity when hanging objects and is less prone to wobbling or tipping. Connecting rod 2 can be attached to base plate 1 by welding, bolting, or other methods to ensure a robust connection.
[0028] The hook head 3 is welded to one end of the connecting rod 2, with the angle formed by the top of the hook head 3 and the top of the connecting rod 2 ranging from 120° to 150°. This angle allows the hook head 3 to provide better support when hanging objects and prevents them from slipping. The distance between the center of the hook head 3 and the front of the base plate 1 is 20 cm to 30 cm. This distance can be adjusted depending on the actual usage scenario to accommodate the hanging requirements of objects of different sizes. The head of the hook head 3 is shaped like a hemispherical disc. This shape increases the contact area with the suspended objects, reduces the pressure on the objects, and protects them from damage.The hook head 3 and the end of the connecting rod 2 are joined together by welding, whereby the welding can ensure the connection strength between the two, making the hook more robust and durable.
[0029] The weight reduction hole 4 is formed on the back of the base plate 1 and extends to the end of the connecting rod 2. Providing the weight reduction hole 4 not only reduces the weight of the hook, but also allows for some savings in material costs. At the same time, the presence of the weight reduction hole 4 does not significantly reduce the overall strength of the hook, as the load situation and the structural stability of the hook were comprehensively considered during the design process.
[0030] The implementation principle of the present embodiment is as follows: Through a reasonable structural design of this hook, such as the rectangular shape and rounded design of the base plate 1, the rectangular cross-section and specific connection position of the connecting rod 2, the angle and shape design of the hook head 3, and the arrangement of the weight-reduction hole 4, the connection robustness and operational stability of the hook are improved while simultaneously reducing weight. Compared to conventional hooks, the hook according to the present utility model can better meet the requirements of scenarios demanding high connection robustness, has a longer service life, offers improved operational safety and comfort, and represents a significant improvement over the prior art.
[0031] The foregoing describes only preferred embodiments of the present utility model, which are not intended to limit the scope of the present utility model. All modifications, equivalent replacements, and improvements made within the spirit and principles of the present utility model should be included within the scope of protection of the present utility model. SUMMARY
[0032] This utility model relates to the technical field of suspending objects, in particular to a lightweight and robust hook comprising a base plate, a connecting rod, a hook head, and a weight-reducing hole.
