The invention discloses an embedded chained air pressure adsorption fixing logistics trolley bottom board. The embedded chained air pressure adsorption fixing logistics trolley bottom board structurally comprises a pull rod, a semicircular seat, trundles, cramps, a bottom board, depth grooves and chained air pressure adsorption fixing mechanisms. The semicircular seat is welded to the left end ofthe bottom board, the lower end of the pull rod is movably connected into the semicircular seat, the more than two trundles are arranged and mechanically connected to the four corners of the lower surface of the bottom board, the cramps are welded to the left end of the front face of the bottom board, and the two depth grooves are formed and embedded in the left end and the right end of the uppersurface of the bottom board. Through arrangement of the chained air pressure adsorption fixing mechanisms, air pressure adsorption mechanisms and elastic reset drawing and pulling mechanisms are matched with each other, the surface on the periphery of a fish tank is fixed in an air pressure adsorption mode, the contact area is large, no contact gap exists, the surface of the fish tank is not squeezed, the transfer process of the fish tank is conducted smoothly, and the surface of the fish tank is prevented from being scratched and crushed.
