Abstract:
1. An assembling structure for a door lock, comprising: a lever having a compartment, an engaging member and an assembling hole, the engaging member being formed in the compartment and the assembling hole being connected with the compartment; a lock core unit inserted into the lever, with a passage through the assembling hole; an axial tube inserted into the compartment of the lever, the axial tube including a longitudinal slot and a transverse-retaining recess formed therein; such that the longitudinal slot is connected with the transverse-retaining recess; and an adapter combined with an end of the axial tube to thereby assemble the lock core unit, the adapter including a positioning member; wherein assembling the axial tube and the adapter, the positioning member of the adapter is engaged in and confined within the transverse-retaining recess of the axial tube via the longitudinal slot, thereby constituting a combination unit of the axial tube and the adapter and preventing disengagement of the combination unit of the axial tube and the adapter in the following assembling operation; and wherein assembling the lever and the combination unit of the axial tube and the adapter, the engaging member of the lever is engaged with the longitudinal slot of the axial tube and further engaged with the positioning member of the adapter so as to prevent releasing the positioning member of the adapter from the transverse-retaining recess of the axial tube, and, due to obstruction of the engaging member of the lever in the longitudinal slot of the axial tube, the positioning member of the adapter cannot return to the longitudinal slot of the axial tube such that no rotational movement of the adapter with respect to the axial tube is allowed.
