Lock structure

摘要

A lock structure includes a mounting plate, a positioning member, an escutcheon and a constraining member, wherein the mounting plate comprises a ring wall, guiding slot and a limiting slot, and the escutcheon comprises a limiting protrusion. The positioning member is disposed in the limiting slot and clamped between the escutcheon and the constraining member. The limiting protrusion penetrates the guiding slot of the escutcheon and is constrained inside the limiting slot. The limiting protrusion of the escutcheon is blockable by the constraining member to prevent the rotating escutcheon from separation from the mounting plate.

1. A lock structure includes:
a mounting plate having a ring wall, a guiding slot and a limiting slot communicated with the guiding slot, wherein the guiding slot and the limiting slot are both formed at and are defined by the ring wall; a positioning member disposed in the limiting slot and having at least one positioning slot; an escutcheon covering the mounting plate and having a limiting protrusion, wherein the limiting protrusion passes through the guiding slot of the mounting plate to enter the limiting slot, and the limiting protrusion of the escutcheon in the limiting slot is rotatable to enter the positioning slot to make the limiting protrusion constrained inside the limiting slot of the mounting plate and the at least one positioning slot of the positioning member; and a constraining plate having a constraining member disposed in the limiting slot, wherein the positioning member is clamped between the mounting plate and the constraining member, and the limiting protrusion of the escutcheon is blockable by the constraining member to limit the escutcheon from rotation and a main body is engaged with the constraining plate.
