Embodiment

See also Fig. 2, Fig. 3 and Fig. 4, the utility model provides a kind of fastening structure improvement of optical disk cartridge, this optical disk cartridge is a kind of device in order to the collection discs, this optical disk cartridge comprises that a lower cover 10 and a loam cake 20 form, lower cover 10 is wherein made with plastic material, it is a disc, its end face can be in order to place CD, LD, VCD, various discs such as DVD, this lower cover 10 is the one-body molded hollow form reference column 11 that is provided with in the center, this reference column 11 is upright in lower cover 10 end faces, this reference column 11 has suitable height, can be inserted into this loam cake 20 inside, the center hole of discs then can be sheathed on this reference column 11, and utilizes this reference column 11 to be located.

On this lower cover 10, be provided with most the baffle plates 12 that are circular arc in addition, these baffle plates 12 adopt the equi-spaced apart setting, these baffle plates 12 are located at lower cover 10 end face proximal edge places, and these baffle plates 12 are circular around forming, the nearly end place of these baffle plate 12 outer walls respectively is provided with a buckling groove 13, these buckling grooves 13 along baffle plate 12 levels to extending suitable length, and these buckling groove 13 1 ends respectively be provided with a degree of depth more shallow inlet 14 so that cooperate with the locking member 22 of loam cake 20.

Another body formed diameter that is provided with is big circular isolated body 15 than reference column 11 on this lower cover 10, this isolated body 15 is positioned at reference column 11 peripheral suitably distances, can have the bed hedgehopping effect, be positioned over undermost discs in suitable height for supporting, in order to prevent being positioned over directly contact lower cover 10 of undermost discs surface, avoid causing the scratch of discs.
