Description

Technical Field

[0001] The utility model relates to the technical field of chains, in particular to an anti-breakage metal chain. Background Art

[0002] A chain is a linear structure composed of interconnected links or segments. This structure can be made from a variety of materials, including metal, plastic, and rubber. Chains are widely used in industry, transportation, and machinery. Furthermore, metal chains can improve the reliability and durability of mechanical equipment due to their high strength and wear resistance.

[0003] A search revealed a document with the publication number CN216343698U, which discloses a high-strength, break-resistant metal chain. The document relates to the field of chain technology and includes a first inner link plate, a second inner link plate, a first outer link plate, a second outer link plate, and a buffer mechanism. Each of the first inner link plate, the second inner link plate, the first outer link plate, and the second outer link plate has a rectangular through-hole formed on one side, and the buffer mechanism is disposed on the bottom wall of the rectangular through-hole. The buffer mechanism includes an outer tube, a shock-absorbing spring, an elastic column, and a buffer plate. The outer tube is screw-mounted on the bottom wall of the rectangular through-hole, and a placement slot is formed on the top of the outer tube. In this utility model, rectangular through-holes are formed on one side of the first inner link plate, the second inner link plate, the first outer link plate, and the second outer link plate, and the buffer mechanism is disposed on the bottom wall of the rectangular through-hole. When the top of each link plate is subjected to an impact force, the buffer plate buffers a portion of the impact force, and the shock-absorbing spring and the elastic column buffer the remaining impact force, making it difficult for the link plates to crack due to the impact force.

[0004] However, this patent only solves the problem that when the top of each chain plate is subjected to impact force, the buffer plate will buffer part of the impact force, and then the shock-absorbing spring and the elastic column will buffer the remaining part of the impact force. The impact force is unlikely to crack each chain plate, and it does not solve the problem that each chain plate is only connected to it by a rotating shaft. When the chain is subjected to a lateral impact, it is easy to cause the chain to break, affecting the service life of the metal chain. Utility Model Content

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figure 1 、 Figure 2 and Figure 4 The first link 2 and the second link 3 are connected to each other by the spring, and the spring has an outer end which is fixed to the first link 2 and the outer end which is fixed to the second link 3. The second link 2 and the second link 3 are connected to each other by the spring.

[0041] Specifically, the chain consists of a first link plate 1 and a second link plate 16, which are interconnected by a series of connectors to achieve the desired length. The first link plates 1 are connected by a first connecting plate 2 and a second connecting plate 3. These connecting plates are connected by a connecting shaft 4, and the ends of the connecting shaft 4 are riveted together by a limit block 1 5 to ensure the overall structural stability of the chain. With the assistance of the connecting plates, the tension of a strong spring 9 supports the relationship between the first connecting plate 2 and the second connecting plate 3. This design allows the chain to have a certain degree of elasticity when subjected to lateral impact, thereby reducing the damage caused by the impact. At the same time, the limit block 2 8 has a certain amount of movement space within the limit slot 6, which further enhances the impact resistance of the chain system. The design of the slide 15 and the connection with the limit block 2 8 ensure the stability and reliability of the chain and play a supporting role during chain movement. The interaction between the auxiliary shaft 7 and the limit block 2 8 further strengthens the connection between the various components of the chain and provides additional support and limiting functions when necessary.

[0042] Reference Figure 3 and Figure 5 A through hole 10 is opened inside the first chain plate 1, and a support column 11 is arranged inside the through hole 10. The support column 11 is arranged in a M shape and is fixedly connected to the inside of the first chain plate 1 in a rectangular array. A core layer 14 is provided inside the first chain plate 1. The core layer 14 is made of alloy steel. The outer wall of the core layer 14 is fixedly connected to a wrapping layer 13. The wrapping layer 13 is made of rubber. The outer wall of the wrapping layer 13 is fixedly connected to a protective layer 12. The protective layer 12 is made of polyester fiber.

[0043] Specifically, the through-hole 10 and the support columns 11 within it play a crucial role. By providing the through-hole 10 within the first link plate 1 and arranging multiple cross-shaped support columns 11 within it, the chain not only reduces weight but also improves overall strength. This structural design effectively distributes weight and tension across the multiple support columns 11, thereby increasing the chain's load-bearing capacity and durability. The core layer 14, made of alloy steel, is the chain's key support structure. It bears the responsibility of bearing tension and weight, ensuring the chain remains stable and strong during operation. Meanwhile, the wrapping layer 13 is covered with a rubber material, which not only increases the chain's flexibility and wear resistance but also reduces metal-to-metal friction, effectively extending its service life. The rubber layer also acts as a vibration dampener and reduces noise, ensuring smoother and quieter operation. The protective layer 12, made of polyester fiber, primarily protects the chain from corrosion and damage from the external environment. This layer not only provides additional protection but also helps extend the chain's service life, ensuring it maintains optimal operating conditions even in harsh environments.

[0044] Working principle: When using the anti-breakage metal chain, the chain is composed of multiple groups of first chain plates 1 and second chain plates 16 combined into the required length. The first chain plates 1 are connected to each other through the first connecting plate 2 and the second connecting plate 3 on another first chain plate 1. The connecting shaft 4 passes through the first connecting plate 2 and the second connecting plate 3. The two ends of the connecting shaft 4 are riveted through the limit block 1 5. At the same time, the auxiliary shaft 7 on the first connecting plate 2 and the limit block 2 8 are limited and assisted in the limit groove 6 and the slide groove 15 in the second connecting plate 3. When the chain generates a lateral impact, the second connecting plate 3 is on the connecting shaft 4. The first and second connecting plates 2 and 3 have a certain amount of interaction space, and the tension between them is supported by a strong spring 9. The limit block 2 8 also has a certain amount of interaction space within the limit slot 6. Therefore, when the first link plate 1 is impacted, it can be displaced a certain distance to reduce the damage caused by the impact. At the same time, the through hole 10 opened inside the first link plate 1 and the multiple support columns 11 inside the through hole 10 can support the first link plate 1, reducing the weight of the chain while increasing the strength of the chain. The support columns 11 are in a cross-shaped shape and support the first link plate 1 inside the through hole 10. The core layer 14 is made of alloy steel. This layer is the main support structure of the chain, responsible for bearing tension and weight. The wrapping layer 13 is made of rubber and is used to cover the metal material of the core layer 14. This layer can increase the flexibility and wear resistance of the chain, reduce metal-to-metal friction, and also play a role in shock absorption and noise reduction. The protective layer 12 is made of polyester fiber. This layer is mainly used to protect the chain from corrosion and damage from the external environment, and also provides additional protection to extend the service life of the chain.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
