[0002] In the industrial production field, conveyor chains are a key component for material transportation and are widely used in various production lines, such as automobile manufacturing, food processing, and logistics warehousing. Especially in the metallurgical conveying field, conveyor chains can be used to transport metallurgical products. Compared with roller conveyors, conveyor chains have the advantages of simple structure, light weight, and low operating and maintenance costs.

[0003] However, traditional industrial conveyor chains are inconvenient to install and disassemble. In harsh environments and under heavy loads, the chains are prone to wear and breakage. Frequent replacements not only lead to a significant increase in production costs, but chain failures can also cause production accidents, damage equipment, and threaten the safety of operators. When maintenance workers maintain or replace the chains, they often need to use a variety of complex tools and spend hours or even days, which seriously affects production progress and increases the company's downtime costs. To address this, we have proposed a convenient and durable industrial conveyor chain that is easy to disassemble. Utility Model Content

The sliders 15 are slidably connected to the guide grooves 12. The anti-detachment component 6 is provided with a conical opening 16 on one side of the inner cavity 10. The conical opening 16 is fitted with the elastic element 7. The sliding connection between the sliders 15 and the guide grooves 12 effectively ensures the smoothness of the sliding of the anti-detachment component 6. The conical opening 16 facilitates the elastic element 7 to squeeze out the anti-detachment component 6 and complete the locking.

[0021] Furthermore, the elastic element 7 consists of three parts: a mating block 17, a spring 18, and a sliding element 19. The two ends of the spring 18 are welded between the mating block 17 and the second slider 21. The mating block 17 is welded to the shaft end inside the inner cavity 10 on the side away from the spring 18. The second slider 21 is provided with a pin 20 on the side away from the spring 18. The outer side of the pin 20 is connected to the conical opening 16. The shaft end of the pin 20 is frustoconical. The side wall of the sliding element 19 is provided with a set of second sliders 21 arranged in a ring array. The second slider 21 is connected to the guide groove 23 in a sliding fit. The spring 18 is always in a compressed state, which effectively ensures the overall structural stability of the quick-release structure. The sliding fit between the second slider 21 and the guide groove 23 effectively ensures the smooth movement of the elastic element 7.

[0024] Working Principle: Install this easy-to-disassemble durable industrial conveyor chain correctly according to the diagram. In the basic structure of the chain, the inner link 1 has two symmetrically distributed rollers 2. The rollers 2, through their rotational engagement with the inner link 1, reduce the frictional resistance between the chain and the track, ensuring smooth material conveying. The sleeve 8 is fitted inside the rollers 2 and tightly connected to the inner link 1. It also engages with the outer link 3 to achieve a stable connection between the inner link 1 and the outer link 3. The outer link 3 is connected by a pin. 9 passes through the sleeve 8, achieving a rotatable connection with the inner link 1. The outer link plate 4 rotates around the inner link 1 and the outer link 3, forming the basic structural unit of the chain, bearing the working load of material conveying. During chain assembly, the quick-release structure plays a key role. The quick-release structure consists of a protective cover 5, an anti-detachment component 6, and an elastic component 7. Align the outer link plate 4 with the pin 9 and press the quick-release structure. At this time, the elastic component 7 is compressed, and the anti-detachment component 6 temporarily loses its obstruction due to the retraction of the elastic component 7. Then, the outer link plate 4 is sleeved... Located on one side of the shaft end of pin 9, after the quick-release structure is released, the elastic element 7 rebounds, and its ejector pin 20 engages with the conical opening 16 of the anti-detachment element 6, squeezing out the anti-detachment element 6. The slider 15 on the anti-detachment element 6 slides along the guide groove 12 until the anti-detachment element 6 is in contact with the side wall of the outer chain plate 4, completing the engagement between the outer chain plate 4 and the pin 9, and realizing the quick assembly of the chain. When the chain needs to be disassembled or the chain links need to be replaced, first remove the protective cover 5, insert the outer circular rod into the inner cavity 10 of the pin 9, and the circular rod shaft... The compression of the elastic element 7 causes the spring 18 in the elastic element 7 to further contract. The slider 21 on the slider 19 slides along the guide groove 13, and the ejector pin 20 disengages from the conical opening 16. After the anti-disengagement component 6 loses the support of the elastic element 7, the slider 15 slides along the guide groove 12 into the telescopic cavity 11. At this time, the engagement between the outer chain plate 4 and the pin 9 is released. Then the outer chain plate 4 can be removed, and the pin 9 can be removed from the sleeve 8 to complete the disassembly of the chain and the replacement of the chain links.
