Description
Technical field
The utility model relates to a kind of CD-fixing device, is the improvement technology of the disc stationary installation of optical disk cartridge specifically.
Background technology
In order to protect CD effectively, existing commercially available CD, VCD, DVD disc generally all is placed in the special box, and the optical disk cartridge of the at present seen CD of people, VCD disc is all comparatively low-grade, very easily causes the damage of disc.For this reason, people have carried out a lot of improvement at the disc stationary installation of optical disk cartridge, as the direct release type stationary installation of spacer, this stationary installation is with back-off position spacer outward by a reference column and reference column and forms, downward pressure to reference column, pass through linking portion, transfer horizontal drag force to the reference column center, affect spacer, make on the spacer back-off position excircle diameter dimension less than disc center-hole diameter size, disc takes out, the shortcoming that there is the single low grade of outward appearance in this stationary installation, easily causes disc to damage.The utility model has different structural principles with above-mentioned stationary installation.
Summary of the invention
The purpose of this utility model provides that a kind of structural principle novelty, good looking appearance, processing technology are simple, the disc stationary installation of long-lived optical disk cartridge.
Now be achieved through the following technical solutions the utility model purpose.
A kind of disc stationary installation of optical disk cartridge, comprise the hollow cylindrical reference column (1) that is arranged on the optical disk cartridge drain pan, reference column (1) is provided with back-off position (5), it is characterized in that: described reference column (1) is plano-convex frustum (6) with the position that is connected between the optical disk cartridge drain pan, have spiral groove (8) on reference column (1) and the plano-convex frustum (6), spiral groove (8) is evenly spaced apart, and back-off position (5) are distributed on the locating piece (4) that reference column (1) is separated into by groove (8).
Described plano-convex frustum (6) is gone up or the optical disk cartridge drain pan of close plano-convex frustum (6) is provided with bracing ring (7).
Place, described plano-convex frustum (6) top has and back-off position (5) corresponding technology via holes (10).
Described spiral groove (8) is four or six or eight.
The utility model compared with prior art has the following advantages.
The utility model is provided with evenly spiral groove spaced apart on the reference column of stationary installation and plano-convex frustum, the back-off position is distributed on the part locating piece.When pushing the top of reference column, because the spiral groove on reference column and the plano-convex frustum has certain interval, and the material (PP) that constitutes this stationary installation has the characteristics of high tenacity, add the space at the bottom of reference column and the plano-convex frustum, downward pressure is the tractive force of the hand of spiral along the spiral groove directional steering, make that spacer moves towards the spiral groove direction on the reference column, spiral groove between spacer narrows down, the circle diameter of reference column diminishes, back-off position outer circumference diameter dimension is less than disc center-hole diameter size, and disc takes out.Affect the horizontal drag force of spacer different in the hand of spiral tractive force that affects spacer in the utility model and the common stationary installation, visibly different structural principle is arranged.And spacer is interconnected to reference column, changes in the past that the monolithic spacer has only unidirectional support force, the situation that is easily fractureed when stressed, thus increased serviceable life of stationary installation.Groove in the utility model shape in the shape of a spiral distributes and offers along the direction of axis line of reference column, spiral helicine groove is given aesthetic feeling, offer along the direction of axis line of reference column and also to be convenient to the optical disk cartridge plastic mould, make the processing technology of optical disk cartridge become simple along the direction of axis line die sinking.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1, Fig. 2 and shown in Figure 3, the disc stationary installation of optical disk cartridge of the present utility model mainly is provided with a hollow cylindrical reference column 1 on the optical disk cartridge drain pan, and reference column 1 is a plano-convex frustum 6 with the position that is connected between the optical disk cartridge drain pan.On reference column 1 and plano-convex frustum 6, have six spiral grooves 8; groove 8 is distributed on reference column 1 and the plano-convex frustum 6 in evenly spaced mode; certainly; groove 8 is not limited only to six; can also be four or eight; mainly be to satisfy user's demand, in addition, the improvement distortion that is similar to the spiral fashion profile is all in the protection domain of this patent.Back-off position 5 with at interval position distribution on locating piece, when being separated into six spacers by six grooves such as reference column 1,5 of back-off positions are distributed on first and third, six spacer 4, this distribution mode is that mainly the force rate that back-off position 5 is acted on the disc 9 is more even, in order to avoid damage disc 9.Groove 8 is offered along the direction of axis line of reference column, have and back-off position 5 corresponding technology via holes 10 at place, plano-convex frustum 6 tops simultaneously, the purpose of doing so mainly is to reduce optical disk cartridge processing technology difficulty, because, the optical disk cartridge plastic mould can make the structure of plastic mould become more simple during towards a direction demoulding.For increasing the strong point of stationary installation disc, prevent to scratch the disc information layer again, on the plano-convex frustum 6 or near on the optical disk cartridge drain pan of plano-convex frustum 6 bracing ring 7 is being set, certainly, this bracing ring 7 can also be to be evenly back-up block spaced apart.Fig. 5 and Fig. 6 have shown that disc is deposited and the synoptic diagram when taking out state, when putting into disc 9, disc 9 center pits move down along 5 inclined-planes, back-off position of spacer 4, spacer 3,4 is out of shape towards the hand of spiral, back-off position 5 outer circumference are dwindled, disc 9 is fallen the support level of bracing ring 7, and 5 bounce-backs of back-off position enlarge, and disc 9 is firmly fastened; When taking out disc 9, push the top of reference column 1 downwards, spacer 3,4 moves towards the hand of spiral, spiral groove 8 between the spacer 3,4 narrows down, the circle diameter of reference column 1 diminishes, cause back-off position 5 outer circumference diameter dimensions less than disc 9 center-hole diameter sizes, thereby with disc 9 convenient taking-ups.
The utility model not only can use at the bottom of the box body as optical disk cartridge, also can use at box body face simultaneously, thereby fix two discs 9, and can install one or more interlayers additional in box, makes this stationary installation can hold more disc 9.
Above-mentioned is the utility model most preferred embodiment, changes as the similar structures that uses the utility model instructions and accompanying drawing content to be done, and all is included in the protection domain of the present utility model.
