The invention relates to an anti-falling compact shelf, which comprises a shelf body, support frames, sliding grooves and wheels; the anti-falling compact shelf is characterized in that the support frames, which can be overlapped, are fixedly arranged at the bottom of the shelf body of the compact shelf, and are arranged in a square sliding groove which is provided with an opening facing upwards in the middle; two sliding grooves are arranged on the front part of the shelf body, two sliding grooves are arranged on the back part of the shelf body and two sliding grooves are arranged in the middle of the shelf body; the length of the single side of each support frames is more than twice the length of the compact shelf; the support frames, which face left side, are arranged in a same sliding groove, and the support frames, which face right side, are arranged in another sliding groove; the wheels are arranged at the tail ends of the support frames; a convex triangle is arranged in the middle of the bottom of the square groove, and correspondingly, triangular concave rings, which face inwards, are arranged in the middles of the wheels of the support frames; the wheels are connected to an electric motor by virtue of connecting rods; and the electric motor is connected to a controller. Based on optimization, the compact shelf disclosed by the invention, with the adoption of the square sliding groove and the extended support frames, can increase the relative area of the bottom of the shelf body, so that the stability of the shelf body is relatively enhanced, and the stability of the integral compact shelf is greatly improved; and moreover, the compact shelf is smooth to slide and is relatively convenient to install.
