AI Technical Summary
Technical Problem
During use, dust and other impurities can easily enter the gap between the pin and the sleeve of the existing chain, leading to accelerated wear of the components and affecting transmission efficiency and service life.
Method used
The dustproof components, including a protective block and a sealing block, prevent dust from entering by sealing the gap between the sleeve and the roller, and facilitate disassembly and installation through the connecting components. The sealing block's endurance is improved by utilizing a push spring.
Benefits of technology
It effectively prevents dust from entering the gap between the bushing and the roller, reduces wear, improves the service life and transmission efficiency of the chain, and facilitates maintenance and disassembly.

Abstract
The utility model relates to the technical field of chains, and discloses an anti-attrition dustproof chain structure which comprises a chain body, a dustproof assembly, a first protection block and a second protection block, wherein the dustproof assembly is rotationally arranged at the two ends of a sleeve of the chain body and used for preventing dust from entering a roller gap between the sleeve and the chain body, and the first protection block and the second protection block are arranged outside the sleeve in a sleeving mode. Mounting grooves are formed in the first protection block and the second protection block, sealing blocks are slidably inserted into the mounting grooves, and the sealing blocks located outside the mounting grooves abut against the chain plates of the chain body. The dustproof assembly is reasonable in structure, the gap between the sleeve and the roller can be sealed, external dust and sundries are prevented from entering the gap between the sleeve and the roller, a user can conveniently detach the dustproof assembly from a chain, the cruising ability of the dustproof assembly can be improved, and the protection performance is high.
