Description

Technical Field

[0001] This application relates to the field of chains, and more particularly to an anti-sparking chain for a liquefied gas cylinder conveyor line. Background Technology

[0002] Chains, as common transmission devices, are widely used in heavy machinery, bicycles, escalators, and other fields. In transmission structures where high transmission precision is not required, sprockets and chain drives are mostly used. A chain is usually composed of several chain links connected by chain plates and fixed in series with connecting pins. A complete chain unit may include components such as two inner chain plates, two outer chain plates, bushings, pins, and rollers.

[0003] Traditional chains present several challenges in assembly and use. For instance, the connections between chain links may not be secure enough, making them prone to loosening during transport or use, thus affecting the chain's transmission efficiency and safety. Furthermore, some chains have complex self-locking mechanisms, making installation and disassembly difficult, and hindering subsequent maintenance and partial replacement. Utility Model Content

[0006] A spark-proof chain for a liquefied petroleum gas cylinder conveying line includes several adjacent chain links. Each chain link includes an integrally formed first connecting part, a middle part, and a second connecting part. A connecting block is provided at the end of the first connecting part away from the middle part. The connecting block is hemispherical, and one end of the arc-shaped surface of the connecting block is fixedly connected to the first connecting part. A connecting groove that mates with the connecting block is provided on the side of the second connecting part away from the middle part.

[0007] By adopting the above technical solution, the connecting block of one link is inserted into the connecting groove of another link, and several links are connected end to end to assemble into a chain.

[0008] Optionally, the connecting block is provided with limit plates on both the upper and lower sides, and the second connecting part is provided with a connecting slot communicating with the connecting groove on one side. The connecting slot allows the connecting block and the limit block to pass through. The second connecting part is provided with a limit slot on the side away from the connecting slot, and the limit slot cooperates with the limit plate.

[0009] By adopting the above technical solution, the connecting block is placed in the connecting groove through the connecting slot, and the limiting plate on one side of the connecting block is located in the limiting slot, which improves the connection stability of adjacent chain links and facilitates the rotation of the connecting block in the connecting groove.

[0010] Optionally, the limiting plate is provided with fixing plates on both sides that are connected to the intermediate plate.

[0011] By adopting the above technical solution, the connection strength between the limiting plate and the intermediate plate is enhanced by fixing the plate.
