Description

The multi-disc optical disk box

Technical field

The utility model relates to a kind of multi-disc optical disk box, refer in particular to a kind of can be in order to collect the container of most sheet discs, be that reference column at lower cover is improved, produce distortion, skew and can effectively prevent to be erected in down the reference column that covers, and lower cover and reference column adopt one-body molded design, and the optical disk cartridge with the effect of reducing cost.

Background technology

Optical disk cartridge is a kind of container in order to the collection discs, and on the market optical disk cartridge all styles of, kenel are extremely many.See also Fig. 1, it is a kind of cartridge type optical disk cartridge of known technology, this optical disk cartridge includes a lower cover 10a and a loam cake 20a, this lower cover 10a is a disc, can be in order to place various discs (as CD, LD, VCD, DVD etc.), this lower cover 10a is the one-body molded reference column 11a that is provided with a hollow form in the center, and this reference column 11a has suitable height, can be inserted into this loam cake 20a inside.So the center hole of discs then can be sheathed on this reference column 11a, and utilizes this reference column 11a to be located.

This loam cake 20a is that hollow and bottom are opening-like, and the inner accommodation space 21a that forms of this loam cake 20a can be in order to ccontaining discs.This loam cake 20a bottom is provided with the clamping sheet 22a of most horizontal protrusions, and this lower cover 10a edge stretches out and be formed with a ring flange 12a, this flange 12a be provided with most with the corresponding buckling groove 13a of clamping sheet 22a.When this loam cake 20a lid places this lower cover 10a to go up, can utilize relatively rotating of this lower cover 10a and this loam cake 20a, these clamping sheets 22a is connected among the corresponding buckling groove 13a, make snapping together that this lower cover 10a and this loam cake 20a can be firm.

But the optical disk cartridge of above-mentioned known technology, the reference column 11a of lower cover 10a is a hollow form, and have than long length, and this reference column 11a is shaped in lower cover 10a, therefore at this lower cover 10a and this reference column 11a ejection formation, and after the axle of mould is extracted out by reference column 11a is inner, the reference column 11a of this hollow form produces distortion because of factors such as wall thickness dimension deviation and cooling shrinkage factors easily, make the reference column 11a that is erected on this lower cover 10a produce distortion, skew, be difficult to keep preferable verticality, even the distortion that causes lower cover 10a that can be related, and make the disqualification rate of product significantly improve.

In order to solve above-mentioned disappearance, therefore there is a kind of optical disk cartridge to arise at the historic moment, seeing also Fig. 2, is the optical disk cartridge of another kind of known technology, and this optical disk cartridge roughly optical disk cartridge with above-mentioned is identical, include a lower cover 30a and a loam cake 40a, this lower cover 30a is a disc, can be in order to place various discs, and this lower cover 30a is provided with a reference column 31a in the center, this reference column 31a has suitable height, can be inserted into this loam cake 40a inside.

This loam cake 40a is that hollow and bottom are opening-like, and the inner accommodation space 41a that forms of this loam cake 40a can be in order to ccontaining discs.The bottom of this loam cake 40a is provided with the clamping sheet 42a of most horizontal protrusions, and this lower cover 30a edge stretches out and be formed with a ring flange 32a, this flange 32a be provided with most with the corresponding buckling groove 33a of clamping sheet 42a.When this loam cake 40a lid places this lower cover 30a to go up, can utilize relatively rotating of this lower cover 30a and this loam cake 40a, these clamping sheets 42a is connected among the corresponding buckling groove 33a, this lower cover 30a and this loam cake 40a are snapped together.

This optical disk cartridge mainly is that lower cover 30a and location piece 31a are adopted the combined type design, that is this lower cover 30a separates with this reference column 31a, and go up and this reference column 31a lower end is respectively equipped with corresponding screw 34a and bolt 35a in this lower cover 30a, make this reference column 31a lower end can utilize bolt 35a to be bolted in the screw 34a of this lower cover 30a, and make this reference column 31a be connected in lower cover 30a with array mode, because this reference column 31a is made up of most microscler fin 36a, need not make hollow shape, so the reference column 31a that can effectively prevent to be erected on this lower cover 30a produces skew, can keep preferable verticality, prevent to cause lower cover 30a distortion.

But above-mentioned known optical disk cartridge adopts the combined type design with lower cover 30a and reference column 31a, therefore can increase the number of spare part, causes and manufactures and the inconvenience of assembling, makes the raising that cost is relative.

As from the foregoing, above-mentioned known optical disk cartridge uses in the manufacturing and reality, obviously has inconvenience and lacks existence, and can wait to be improved.

The property improved of the above-mentioned disappearance of the utility model people thoughts is that the spy concentrates on studies and cooperates scientific principle utilization, proposes a kind of reasonable in design and effectively improve the utility model of above-mentioned disappearance finally.

The utility model content

Fundamental purpose of the present utility model is to provide a kind of multi-disc optical disk box, the reference column that covers be can effectively prevent to be erected in down and distortion, skew produced, can keep preferable verticality, and lower cover and reference column adopt one-body molded design, can not increase the number of spare part, can make that the manufacturing and assembling are comparatively convenient, and have the effect that reduces cost.

In order to reach above-mentioned purpose, the utility model provides a kind of multi-disc optical disk box, comprising: a lower cover, and the one-body molded reference column that is provided with in its top, this reference column is made up of most microscler fins; One loam cake, its inner accommodation space that forms, this loam cake lid places under this and covers.

For enabling further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and the explanation usefulness, be not to be used for the utility model is limited.
