Three-dimensional frame

The utility model relates to a three-dimensional frame which comprises an inner frame and an outer frame. The inner frame comprises a hollow frame part, a hollow partition plate and a blocking frame part which can be combined to form a three-dimensional space suitable for containing an exhibit. The outer frame is arranged outside the inner frame to form another three-dimensional space, and the size of the three-dimensional space is matched with that of the outer frame. The outer frame is further provided with a locking structure, so that the inner frame and the outer frame are fixed. The three-dimensional frame can have a three-dimensional sense, the flexibility and the vitality sense of the three-dimensional exhibit are improved, and a user conveniently performs assembly by the aid of the locking structure, so that the three-dimensional exhibit is placed or disassembled.
