Patent ID: 8365929

Claim:
A cabinet frame for easy assembly, comprising: an upper frame and a lower frame each constituted of four corner connectors and four transverse capping pieces; four longitudinal capping pieces connected between four corners of the upper frame and the lower frame, the transverse capping pieces and the longitudinal capping pieces being provided with fitting holes at intervals, characterized in that: sixteen prismatic rods are provided, each prismatic rod correspond to a square bore provided on one end of the transverse capping piece or the longitudinal capping piece in terms of profile and dimension, the prismatic rod can be inserted into a square bore of the longitudinal capping piece, one end of the prismatic rod is provided with a head portion inserted into a countersink of the corner connector, a screw hole is provided in the center of the head; the corner connector is constituted of three right-angled surfaces perpendicular to one another, two of the right-angled surfaces are provided with protrusions respectively inserted into the capping pieces, and the other right-angled surface is provided with two countersinks inserted by the head portions of two prismatic rods, the center of the countersink is provided with a through-hole; the cross section of each of the transverse capping pieces and the longitudinal capping pieces is formed into a cross-sectional shape defined by two squares with first, second, third and fourth surfaces of one bore forming a first square and fifth, sixth, seventh and eighth surfaces of a second bore forming a second square, the second and third surfaces meeting at a corner and the fifth and eighth surfaces meeting at the same corner so that one corner of the first square is attached to one corner of the second square with the third and fifth surfaces being coplanar, each of the transverse capping pieces and the longitudinal capping pieces has three inner surfaces perpendicular to each other to form a stepped surface, the three inner surfaces and two outer surfaces together form two square bores for allowing the protrusions of the corner connector to be inserted therein.
