Abstract
Provided is a push-pull door lock capable of selecting a lever work direction which may be installed without needing to coincide a door opening direction with the lever work direction by driving a driving unit during both a push operation and a pull operation of a lever coupled to each of housings of a front surface and a rear surface of a door to unlock a lock mechanism received in the door. The push-pull door lock includes: a lever that is provided on a front surface of each of housings, which are respectively coupled to an inside and an outside of a door by supports, to pivot in a front-and-back direction and has a protruding portion protruding toward a door; and a selection member that is provided on a rear surface of the housing and limits a pivoting range of the protruding portion in order to select a push operation or a pull operation of the lever.
