Abstract

The invention discloses an antirust door lock. The antirust door lock comprises a lock body, wherein an oil injection channel is formed in the lock body and communicates with the top of an upper marble groove through a plurality of branch channels; and a spring and an upper marble are arranged in the upper marble groove. According to the antirust door lock, parts such as the lock body can be prevented from rusting, the service life of the door lock is prolonged, and the door lock can be quickly lubricated even if the door lock is rusted.

Description

technical field [0001] The invention relates to a door lock, in particular to an antirust door lock.
