The invention discloses a computer table capable of being quickly dismantled and mounted. The computer table comprises a table top body, a sliding groove is formed in the right end of the bottom of the table top body, a convex block is fixedly connected to the middle end of the inner cavity of the sliding groove, a sliding seat is connected between the outer surface of the convex block and the inner cavity of the sliding groove, a storage box is fixedly connected to the bottom of the sliding seat, inner grooves are formed in periphery of the inner surface of the table top body, mounting grooves are formed in the bottoms of the inner cavities of the inner grooves, and support legs are mounted on the inner surfaces of the mounting grooves. According to the computer table capable of being quickly dismantled and mounted, through the action of the sliding groove, the convex block, the sliding seat, the storage box, pulling blocks, pulling rings, round end fixing rods, springs, fixing blocks, the mounting grooves and through holes, the advantages of conveniently dismantling and mounting of the computer table are achieved, and the problems that the using requirements of the computer tablefor people cannot be met, and the practicability of the computer table is lowered due to existing inconvenience of dismantling and mounting when transporting, storing and using of an existing computer table are solved.
