<p>The present invention provides a frame assembly for a prefabricated interior angle rack or display stand capable of being firmly assembled, preventing a generation of a burr during assembly, and being quickly and easily assembled. The frame assembly for a prefabricated interior angle rack or display stand comprises: a support frame having a rod shape at a predetermined length, an L-shaped cross section, and coupling protrusions bent inwards from both lateral ends at right angles; auxiliary frames having a rod shape at a predetermined length and a ㄱ-shaped cross section inserted in the support frame to be coupled; and two-way pin connectors having a hexahedral second body part and coupling pins extended outwards from two surfaces among six surfaces of the second body, three-way pin connectors having a hexahedral third body part and coupling pins extended outwards from three surfaces among six surfaces of the third body part, or four-way pin connectors having a hexahedral fourth body part and coupling pins extended outwards from four surfaces among six surfaces of the fourth body part. The coupling pins of the two-way pin connectors are arranged at right angles to each other. Two among the coupling pins of the third pin connectors are linearly arranged, and the rest coupling fin is arranged at right angles to the two coupling pins or all the three coupling pins are arranged at right angles to each other; two among the coupling pins of the four-way fin connectors are linearly arranged, and the other two coupling pins are arranged at right angles to each other; and coupling grooves are formed on the outer surface of the boundaries between each body part, and each coupling pin inserting the coupling protrusions.</p> |
