Patent ID: 8424931

Claim:
A locking apparatus, comprising: a handle comprising a plurality of pressing protrusions; a base comprising a front cover, a pair of substantially parallel base sidewalls perpendicularly connected to two opposite sides of the front cover, a top cover perpendicularly connected to coplanar ends of the front cover and the base sidewalls to define a receiving space, a pressing through hole in the front cover, and a tongue through hole in the top cover in communication with the receiving space, wherein each base sidewall comprises a plurality of first positioning protrusions received in the receiving space and a plurality of second positioning protrusions received in the receiving space, the first positioning protrusions extend inwards perpendicularly from a first inner surface of the base sidewall at a position directly opposite and near the pressing through hole, the second positioning protrusions extend inwards perpendicularly from the first inner surface of the base sidewall at a position directly opposite but away from the pressing through hole, and each of the base sidewalls defines a guiding gap between the second positioning protrusions and the first positioning protrusions of said each of the base sidewalls; and a slide block slidably received in the receiving space through a pair of resilient elements, wherein the slide block comprises a locking tongue and a pair of guiding ears formed at two opposite sides of the locking tongue, each of the guiding ears is slidably positioned in the guiding gap of a respective one of the base sidewalls, the handle is pivotally connected to the base, the pressing protrusion protrudes into the receiving space through the pressing through hole, the handle pushes the slide block to slide via the pressing protrusions engaging with the slide block, and the locking tongue protrudes out of the base or retracts back into the base according to the movement of the slide block.
