Mechanical equipment chain convenient to maintain

The utility model discloses a mechanical equipment chain convenient to maintain, which comprises chain components, each chain component comprises two inner plates, two connecting pipes are fixedly connected between the two inner plates, the outer sides of the connecting pipes are rotatably connected with chain wheels, pin shafts are inserted into the inner sides of the connecting pipes in a sliding manner, and the two adjacent chain components are connected through outer plates. The detachable chain has the advantages that when part of chain components of the chain need to be detached, the inserting frame slides in the direction away from the pin shaft so that the inserting frame can be separated from the inserting groove, the pin shaft can be taken out in a sliding mode at the moment, and therefore the outer plate can be away from the chain components; when installation is needed, the outer plates are placed on the two adjacent chain components, the pin shafts penetrate through the connecting pipes and the p
