A one-touch door lock of an integrated dual locking structure is provided to maintain a duel locking state only by pressing a handle once in a push button manner. A one-touch door lock of an integrated dual locking structure includes a back set(10), a case(20), an operation hub(30), a dual locking button(40), and a catching member(50). A catching protrusion(44) and a stopping protruding piece(46) are formed at the circumference of a shaft member(42). A positioning boss(48) or a positioning recess is formed at an end opposite to the front end of the operation hub. The catching member is installed at a portion of the through-hole of the case. When the dual locking button is pressed, the catching protrusion of the shaft member is caught by the catching member.
