Description

Technical Field

[0001] The utility model relates to the field of chains, in particular to an outer link plate of a high-strength wear-resistant chain. Background Art

[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction, chain-shaped objects used to block traffic channels, and chains used for mechanical transmission.

[0003] At present, when the outer link plate is used, the inner side of the outer link plate abuts against the inner link plate during the chain transmission process, generating friction, and the pin hole and the pin also generate friction, resulting in the outer link plate being the most easily worn component in the entire chain. After the outer link plate is worn, it will affect the stability of the entire chain, and the outer link plate can only be replaced as a whole.

[0004] Therefore, it is necessary to invent a high-strength wear-resistant chain outer link plate to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a high-strength wear-resistant chain outer link plate to solve the problems raised in the above background technology.

[0007] Preferably, each set of the limiting blocks and limiting slots is provided with four.

[0008] Preferably, the rear side of the annular wear-resistant plate is provided with multiple groups of wear-resistant grooves.

[0010] Technical effects and advantages of this utility model:

[0011] By inserting the wear-resistant tube into the pin hole from the rear side of the outer link plate body, the limit blocks around the wear-resistant tube are placed in the limit grooves on the outer link plate body, and the wear-resistant tube and the annular wear-resistant plate are limited. The wear-resistant tube is used to increase the wear resistance of the pin hole and the pin, and the annular wear-resistant plate is used to improve the wear resistance of the outer link plate body and the inner link plate. After the wear-resistant tube and the annular wear-resistant plate are worn, the wear-resistant tube and the annular wear-resistant plate can be replaced by simply pulling them out of the pin hole, which can conveniently improve the overall wear resistance of the outer link plate body without the need for overall replacement.
