Cabinet frame for easy assembly
View Patent ↗A cabinet frame for easy assembly includes an upper frame and a lower frame each constituted of four corner connectors and four transverse capping pieces, and four longitudinal capping pieces connected between four corners of the upper frame and the lower frame, characterized in that: sixteen prismatic rods are used for connecting corner connectors on four corners of the upper frame and the lower frame with the longitudinal capping pieces, the corner connector being provided with protrusions and countersinks, the cross section of each of the transverse capping pieces and the longitudinal capping pieces being formed into a shape, square bores on both ends of the capping pieces being inserted by the protrusions of the corner connectors. The cabinet frame of the present invention is easy for assembly and has a simple structure. The frame constituted by assembling the corner connectors with the prismatic rods has a stable structure and a large load-bearing capacity. Furthermore, since each of the capping pieces has several mounting surfaces, the thus-obtained cabinet frame can be configured as different forms with flexible and changeable internal space, thereby conforming to the demands for products of different standards and dimensions.
1. 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.
2. The cabinet frame for easy assembly according to claim 1 , wherein each of the three inner surfaces of the longitudinal capping piece or the transverse capping piece is provided with square fitting holes and circular fitting holes at intervals.
3. The cabinet frame for easy assembly according to claim 2 , wherein, a corner of each of the two outer surfaces of the longitudinal capping pieces is formed with an extension strip for forming a guide groove.
4. The cabinet frame for easy assembly according to claim 3 , wherein the upper frame and the lower frame are of equal structure, which is constituted of two front transverse capping pieces, two side transverse capping pieces and four corner connectors, a corner of each of the two outer surfaces of the front transverse capping pieces is formed with an extension strip for forming a guide groove, the front transverse capping pieces having the same dimension as that of the longitudinal capping pieces, a corner of the outer surface of each side transverse capping pieces is provided with an extension strip for forming a groove.
5. The cabinet frame for easy assembly according to claim 4 , wherein each surface of the prismatic rod is provided with holes corresponding to square holes and circular holes on the inner surfaces of the longitudinal capping pieces.
