Compact disc barrel

The invention discloses a compact disc barrel, which solves the problem that compact discs are inconvenient to be taken from the compact disc barrel to be used. The compact disc barrel comprises a cylindrical base, wherein a fixing post is arranged on the base; the compact disc barrel also comprises a protection cover of a tube body provided with an opening at one end; one end of the protection cover is arranged on the base; the protection cover, the base and the fixing post are coaxial; the protection cover can rotate around the axial line; the inner wall of the protection cover is provided with screw threads; a compact disc supporter is sheathed on the fixing post; the compact disc supporter can upwards and downwards slide along the fixing post and is provided with positioning keys fixed with the compact disc supporter; a positioning groove is formed in the side wall of the fixing post in the axial direction of the fixing post; the positioning keys are embedded in the positioning groove; the two ends of the compact disc supporter are respectively butted against the inner wall of the protection cover; a guide slope is arranged at one side of the upper part of the inner wall of the protection cover; the guide slope smoothly extends in the direction approaching to the axial line of the protection cover from bottom to top; and a compact disc outlet is formed in the upper part of the protection cover. The compact discs can be taken to be used only through rotating the protection cover; the operation is convenient; the required space is small; in addition, the compact discs cannot easily fall down; and meanwhile, the compact discs maintain a state of being protected by the protection cover, so dust accumulation or damage cannot easily occur.
