A panic exit door lock comprising, in combination:
- a base (130) adapted to be mounted to an inner side (10a) of a door (10);
- a sliding device (14) slideably mounted to the base (130);
- a latch (120) operably coupled to the sliding device (14) and movable between an extended, latching position and a retracted, unlatching position;
- a cover (20) adapted to be mounted to an outer side (10b) of the door (10);
- a sliding member (34) slideably received in the cover (20) and operably connected to the sliding device (14);
- a handle (24) pivotably mounted to the cover (20) and operably connected to the sliding member (34) such that rotation of the handle (24) causes sliding of the sliding member (34), moving the latch between the extended, latching position and the retracted, unlatching position;
- a limiting member (32) pivotably received in the cover (20) between a blocking position not allowing movement of the sliding member (34) and a release position allowing movement of the sliding member (34), with the handle (24) being rotatable when the limiting member (32) is in the release position, with the handle (24) being not rotatable when the limiting member (32) is in the blocking position;
- an outer cylinder (26) including an outer cylinder body (264) mounted to the cover (20) and an outer lock core (270) rotatably received in the outer cylinder body (264);
- an actuating block (255) fixed to the outer cylinder core (270) to rotate therewith;
- a driving member (44) fixed to the sliding member (34) to move therewith, with the driving member (44) including a rod (442) coupled to the sliding device (14);
- a mover (42) rotatably mounted around the cylinder (26) and including a tab (422) and an actuating bar (424), with the tab (422) being operably connected to the actuating block (255), with the actuating bar (424) being operably connected to the limiting member (32), with the mover (42) being rotated to move the limiting member (32) between the blocking position and the release position when the actuating block (255) is rotated by rotating the outer lock core (270);
- a casing (122) adapted to be mounted to the inner side (10a) of the door (10);
- an inner cylinder (50) including an inner cylinder body (52) mounted to the casing (122) and an inner lock core (54) rotatably received in the inner cylinder body (52);
- a driving block (230) rotatably mounted around the actuating block (255), with the driving block (230) being operably connected to the tab (422) of the mover (42);
- and
- a tongue (58) including front and rear ends (582, 584) spaced in a longitudinal direction, with the rear end (584) fixed to the inner lock core (54), with the front end (582) coupled to the driving block (230), allowing joint rotation of the inner lock core (54), the tongue (58), and the driving block (230), with the mover (42) being rotated to move the limiting member (32) between the blocking position and the release position when the driving block (230) is rotated by rotating the inner lock core (54).
