Claim 0:
1. A door lock device, comprising:
a switch mechanism capable of being operatively switched from a first position to a second position or a third position;
an oblique tongue mechanism, including an oblique tongue body and an oblique tongue drive assembly, the oblique tongue drive assembly being connected to the switch mechanism, wherein, when the switch mechanism is in the first position, the oblique tongue body is in an extended state, when the switch mechanism is switched from the first position to the second position, the switch mechanism drives the oblique tongue drive assembly to drive the oblique tongue body to be in a retracted state, and when the switch mechanism is switched from the first to the third position, the switch mechanism drives the oblique tongue drive assembly to drive the oblique tongue body to be in the retracted state;
a deadbolt mechanism, including a deadbolt body and a deadbolt drive assembly; and
a linkage mechanism connecting the switch mechanism and the deadbolt drive assembly,
wherein, when the switch mechanism is switched from the first position to the second position and the deadbolt body is in the retracted state, the linkage mechanism is adapted to cooperate with the deadbolt drive assembly to drive the deadbolt body to be in the extended state;
when the switch mechanism is switched from the first position to the third position and the deadbolt body is in the extended state, the linkage mechanism is adapted to cooperate with the deadbolt drive assembly to drive the deadbolt body to be in the retracted state; and
when the switch mechanism is switched from the second position or the third position to the first position, the linkage mechanism is disengaged from the deadbolt drive assembly.
