Abstract

The utility model relates to a CD protective sleeve which has the structure that both sides of the existing CD are respectively provided with an upper and lower protective layers which can be detached and mounted, wherein, the two protective layers are respectively provided with a connecting shaft and a hole, and connected together to form a protective sleeve. The protective layers are respectively provided with a CD read-write window, wherein, a layer of protective film is bonded inside the upper protective layer. The outer part of the protective sleeve is provided with a metal protective sheet which is inlaid inside a slide groove arranged on the upper part of the protective sleeve, and a magnetized metal disk bracket is arranged inside the protective sleeve. One corner of the protective sleeve is provided with an optical disk read/write protective opening, and a slide block is arranged inside the optical disk read/write protective opening. With the advantages of simple structure and convenient operation, the utility model can reduce the damage of CDs, and enhance the utilization ratio of the CDs.

Description

The CD protecting cover

The utility model relates to the computer cd field, particularly a kind of CD protecting cover.

At present, the medium that is widely used on information storing device is CD one by one, no matter be disposable CD, still can write, erasable type CD, and itself does not have outer jointing jacket CD, has only for the outer box of wrapping plastics.So just caused people when using CD, often, and caused the damage of optical disc storage face, CD can not normally be used, when serious even cause scrapping of whole disc owing to manipulate improperly.

The purpose of this utility model provides a kind of damage that can protect CD, reduce CD storage face, prolongs the CD CD protecting cover in serviceable life.

The purpose of this utility model is achieved in that

Constitute the CD protecting cover by the last protective seam 1 that contacts with CD storage face with the lower protective layer 2 that contacts with the CD back side; be respectively equipped with CD read and write window 6 on two protective seams; be characterised in that protective seam 1 is provided with coupling spindle 4; lower protective layer 2 is provided with hole 5; two protective seams link by coupling spindle 4 and hole 5; bonding layer protecting film 3 in the last protective seam; the outside CD read and write window of protective sleeve 6 places establish rectangle metal newspaper bluff piece 11; protective sleeve top is provided with sliding tray 16; metal coating sheet 11 connects by the releasable fixed pin and embeds in the sliding tray 16; central authorities establish a rosette carriage 14 that is magnetized in the newspaper sheath, by carriage fixedly convex 7 fix with the circular groove of evagination 8 formation.One jiao in the protective sleeve bottom is provided with optical disk reading Write-protect notch 9, and a sliding shoe 10 is established in its inside.

The utility model is simple in structure, easy to use, can protect CD to reduce damage, prolongs the serviceable life of CD.

Below in conjunction with accompanying drawing the utility model is further described:

A removable protective seam is respectively adorned on two sides at existing CD; last protective seam 1 contacts with CD storage face; lower protective layer 2 contacts with the CD back side; paste the diaphragm 3 that one deck does not damage CD in the last protective seam 1; two independent protection layers combine with hole 5 by the coupling spindle 4 of injection molded; on two protective seams, have CD read and write window 6; shelter from metal coating sheet 11 in the protective sleeve outside; have fixed orifice 12 and spring connection holes 13 on this metal coating sheet; install by releasable fixed pin and CD protecting cover; and can carry out laterally mobile by the sliding tray 16 on protective sleeve top; when CD uses; by the link gear in the driver screening glass 11 is drawn back along sliding tray 16; expose CD read and write window 6; can normally use CD, screening glass 11 covers in CD read and write window 6 when not using under the effect of inner spring.CD itself is supported by a rosette carriage that is magnetized 14, rely on by the carriage of injection molded in the protective sleeve fixedly convex 7 fix with the circular groove that evagination 8 forms, thereby can realize the read-write rotation of CD.The purpose that the rosette carriage is magnetized is to contact firmly with the rotating mechanism in the CD drive.One jiao of design has optical disk reading Write-protect notch 9 in the protective sleeve bottom, and there is a sliding shoe 10 in portion within it, and can shield by moving of sliding shoe 10 makes the information on the CD arbitrarily do not deleted and change.When sliding shoe 10 moves on the protection mouth, detect CD not by write-protect by the testing agency in the CD-ROM drive, and protect a mouthful following time when sliding shoe 10 moves to, CD-ROM drive detects write-protect.15 is the CD drive fixed orifice among the figure.
