## Abstract

A mounting structure including a locking plate disposed between a mount and a frame structure is described. The locking plate is provided with a central locking hole. A screw is provided with a washer that has a plurality of teeth at the outer periphery of its bottom side. The screw is passed through the washer, the mount and the locking plate into the flame structure. The teeth of the washer clutch the surface of the mount and prevent movement with the turning of the screw. The locking plate will slightly elevate with the turning of the screw, imposing a pressure on the screw to stop it from turning. This ensures firm locking of the mount to the frame structure preventing the screw from driving unduly deep into the frame structure to damage the frame structure or the screw threads.

## Claims

### Claim 1

A mounting structure, comprising:
a locking plate that is substantially a plate-like structure having a locking hole at a central position, said locking hole being obliquely cut so that an inner ring thereof forms a spiral shape to facilitate driving of a screw thereinto, said locking plate having three substantially L-shaped pawls at its outer edge, said pawls being spaced apart with two of said pawls opposite each other and one of said pawls facing an open end, a distance from each of said pawls to the center of said locking hole being equivalent to a distance from the center of a through hole of a mount to an outer periphery of said mount, said opposite pawls each having a plate portion at a top side thereof such that said locking plate may firmly retain said mount, said plate portions of said two opposite pawls and a bottom plate of said locking plate flaring slightly outwardly in the direction of said open end so that said mount may be smoothly fitted into said locking plate; and a screw with a washer, said screw having an elongated tip forming a guide portion, said washer having a bottom side with an outer periphery having a plurality of tooth-like portions.
