Description

The optical disk cartridge structure

Technical field

The utility model relates to a kind of optical disk cartridge structure, relates in particular in order to the saving cost, and makes things convenient for the optical disk cartridge of disc accessing.

Background technology

The receiver of CD has many kinds, wherein the CD receiver of cylinder type is wherein a kind of, but the lid of the CD receiver of this cylinder type and the manner of bearing have many kinds again, how to design a simple manner, and having the advantage that makes things convenient for optic disc storage again concurrently simultaneously is important problem.

As shown in Figure 1, be a kind of existing optical disk cartridge, be provided with accommodation space in lid 10a central authorities, and the inboard periphery of lid 10a is provided with projection 11a and the upper surface is provided with a protuberance 12a, other has a bearing 20a, its central portion is provided with an axostylus axostyle 21a, (not shown) when making CD be seated in bearing 20a, can make the medium pore of CD be inserted in the axostylus axostyle 21a of bearing 20a, and several barricades 22a is set on bearing 20a, and locate to be provided with a catching groove 23a in the same way at each barricade 22a respectively, with so that the projection 11a of lid 10a is buckled in the catching groove 23a of bearing 20a, and the protuberance 12a of lid 10a ccontaining the part axostylus axostyle 21a, lid 10a is covered on bearing 20a.

But above-mentioned existing optical disk cartridge has following shortcoming:

1, existing optical disk cartridge is provided with several barricades 22a on bearing 20a, and catching groove 23a is set on barricade 22a, so that fasten lid 10a, but the setting of barricade 22a is not easy to make the CD that is placed on bearing 20a bottom to be removed.

2, existing optical disk cartridge is that several barricades 22a is set on bearing 20a, and being provided with of this barricade 22a spends many plastic material, and increases the Mould Machining cost, thereby productive costs is improved.

Summary of the invention

At the above-mentioned shortcoming of prior art, main purpose of the present utility model is to provide an optical disk cartridge structure, and the CD that makes it be placed on the bearing bottom is convenient is taken.

Secondary objective of the present utility model for an optical disk cartridge structure is provided, makes it reduce manufacturing cost and material cost, to reduce production costs.

According to aforementioned purpose, an optical disk cartridge structure of the present utility model, it is made up of a lid and a bearing, with so that disk cover is gone into the axostylus axostyle on the bearing, CD can be captured in the optical disk cartridge like this, wherein the periphery in bearing is provided with guide groove and button hole, and the bottom in bearing is provided with ring body, the stop ring body is supported in the lower surface that is beneficial to lid, and when rotating lid simultaneously, make the projection on it slip into button hole,, lid is fastened on the bearing with so that projection leans the upper end at button hole via guide groove.

A kind of optical disk cartridge structure of the present utility model comprises: a lid, be hollow housing, and this lid inner edge side is convexly equipped with several projections; An and bearing, its centre protrudes out an axostylus axostyle, wherein, periphery in described bearing is concaved with several guide grooves, and be provided with a button hole this guide groove neighbour, and described bearing bottom is convexly equipped with a ring body, with so that the upper surface of ending at described ring body is supported in the lower surface of described lid, and make described projection slip into described button hole through described guide groove and lean upper end at this button hole, so that described lid fastens with described bearing.

Described optical disk cartridge structure, wherein, described bearing bottom is provided with a ring-type fin.

Described optical disk cartridge structure, wherein, the centre of the described lid recess that sets to the concave, in order to the central portion of CD against.
