Abstract

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.

Example Embodiment

[0013] Figure 1-3 Shown is an embodiment of the invention.
[0014] An optical disc barrel includes a cylindrical base 1, on which a fixing post 2 for axially positioning the optical disc through a disc hole is provided, and a protective cover 3 of a cylinder with an open end. The open end of the protective cover 3 is provided with On the base 1, the shield 3, the base 1, and the fixed post 2 are coaxial, the shield 3 can rotate on the base 1 around the axis of the shield 3, and the inner wall of the shield 3 is provided with threads (not shown in the figure), The fixed post 2 is covered with a disc tray 4, the disc tray 4 can slide up and down along the fixed post 2, the disc tray 4 is provided with a positioning key 5 fixed to the disc tray 4, the fixed post 2 is provided with a positioning groove 6, and the positioning groove 6 is fixed along the The column 2 is axially arranged on the side wall of the fixed column 2, the positioning key 5 is embedded in the positioning groove 6, the two ends of the disc tray 4 are respectively against the inner wall of the shield 3, and the two ends of the disc tray 4 are respectively inserted into the threads of the inner wall of the shield 3 and With threaded fit, the disc tray 4 rises when the shield 3 rotates in one direction, and the disc tray 4 lowers when the shield 3 rotates in the other direction; the upper side of the inner wall of the shield 3 is provided with a guide slope 7 that runs from bottom to top It extends smoothly in the direction close to the axis of the shield 3, and the other side of the upper part of the shield 3 opposite to the guide slope 7 is provided with an optical disc outlet 8.
[0015] The base 1 is provided with an annular slide groove 9 which is provided with an opening on the upper surface of the base 1. The lower edge of the shield 3 is placed in the slide groove 9, and the end of the lower edge of the shield 3 has a greater length in the radial direction of the base 1 The length of the opening of the sliding groove 9 in the radial direction of the base 1, and the shield 3 can rotate on the base 1 along the sliding groove 9 around the axis of the shield 3. After the lower edge of the shield 3 is placed in the slide groove 9, when the shield 3 rotates, the lower edge of the shield 3 slides in the slide groove 9, and the end of the lower edge of the shield 3 in the radial direction of the base 1 is longer than the opening of the slide groove 9 The length in the radial direction of the base 1 can ensure that the shield 3 will not fall out.
[0016] Due to the cooperation of the positioning key 5 and the positioning groove 6, the disc tray 4 cannot rotate in the axial direction on the fixed post 2. When the guard 3 is rotated forward, the threads of the disc tray 4 and the guard 3 slide relatively, so that the disc tray 4 rises with the threads. When the disc hits the guide slope 7, when the disc hits the guide slope 7, the disc will move closer to the side of the disc exit 8 until the disc reaches the highest position. It protrudes from the optical disc exit 8 and can then be used directly. The optical disc can be accessed only by rotating the shield 3, which is convenient to operate, requires a small space, and the optical disc is not easy to fall off. At the same time, the optical disc remains protected by the shield 3 to prevent dust accumulation or damage.
[0017] In addition to the above-mentioned preferred embodiments, the present invention has other embodiments. Those skilled in the art can make various changes and modifications according to the present invention. As long as they do not deviate from the spirit of the present invention, they should all be defined by the appended claims of the present invention. range.
