Stair chain with automatic oiling function for escalator

The utility model relates to the technical field of escalator step chains, in particular to an escalator step chain with an automatic oiling function. The utility model aims to solve the technical problems that the existing step chain device does not have an automatic lubricating oil feeding function, the oiling operation is very tedious and has certain danger, and the existing step chain device does not have a collecting function during oiling maintenance because the step chain is relatively long and large, so that the existing step chain device is inconvenient to operate. After oiling, oil can flow to the ground along with the gear and the step chain, so that waste is caused and the environment is polluted. In order to solve the technical problems, the stair chain with the automatic oiling function for the escalator mainly comprises an oiling mechanism and a collecting mechanism, the stair chain can be automatically oiled and maintained in a timed mode, manual oiling and maintenance are not needed, the poss
