Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, below the utility model is further described with reference to the accompanying drawing embodiment that develops simultaneously.
The CD-fixing device structure with two pawl core optical disk cartridges of present embodiment is an example, but is not limited to use in the lower cover of optical disk cartridge, also can use in arbitrary loose-leaf of optical disk cartridge, and perhaps other need carry out in the CD stationary device.Wherein the structure of optical disk cartridge as shown in Figure 1, but it comprises loam cake 100 and lower cover 300 that folding connects, described lower cover 300 inside surfaces are provided with the stationary installation 200 that is used for fixing CD of the present utility model.
In the present embodiment, the Facad structure figure of stationary installation 200 as shown in Figure 2, it comprises the first pawl face 210 and the second pawl face 220 that is centrosymmetric, the first pawl face 210 is arch with the second pawl face 220 at center symmetric points place and is connected, so that the first pawl face 210 and the second pawl face 220 can be subjected to displacement downwards under external force.Be symmetrical arranged the button bit that is useful on the buckle cd center hole on the first pawl face 210 and the second pawl face 220.Wherein, the first pawl face 210 is provided with first button bit 211, the second pawl face 220 is provided with second button bit 221, first button bit 211 and second button bit 221 are centrosymmetric, and the center-hole diameter size of the adaptive described CD of distance between first button bit 211 and second button bit 221 is with better buckle CD.
In the present embodiment, the first pawl face 210 and the second pawl face, 220 formed arcuate surfaces can be inclined-plane or cambered surface, be preferably and the parallel plane of lower cover 300 inside surfaces, elastically-deformable plastics can take place in simultaneously preferred employing or other resilient materials are made the first pawl face 210 and the second pawl face 220, conveniently to push, avoid damaged compact disk.
In the present embodiment,, be respectively arranged with first supporting surface 230 and second supporting surface 240 that are centrosymmetric in the first pawl face, 210 both sides.First supporting surface 230 and second supporting surface 240 also can be the arch setting, and preferably first supporting surface 230 and second supporting surface 240 are provided with at grade, and the plane at its place is set to be parallel to the face of described lower cover 300 inside surfaces, so that the easier taking-up of CD.Can be provided with reinforcement on first supporting surface 230 and second supporting surface 240, avoiding CD to follow the first pawl face 210 in the second pawl face 220 at the first pawl face 210 of pushing and the second pawl face 220 moves downward, the center pit that supporting CD makes CD comes off from the button bit of the first pawl face 210 and the second pawl face 220.Simultaneously first supporting surface 230 and second supporting surface 240 can preferably adopt hardness preferably material make so that it can better help CD to come off from button bit.Owing to be subjected to the cost restriction, general optical disk cartridge all adopts same material to adopt mould one-body molded, therefore on first supporting surface 230 and second supporting surface 240, reinforcement is set, can effectively improve the hardness of first supporting surface 230 and second supporting surface 240, make CD easier ejection under situation about being without prejudice.Can be chosen in its two front reinforcement 270 is set, as shown in Figure 2; Also can reinforcement 280 be set at its two reverse side, as shown in Figure 3, or pros and cons is provided with reinforcement simultaneously.
In a further embodiment, the junction of the first pawl face and 210 second pawl faces 220 is provided with the first pawl face 210 that can drive under external force and the second pawl face 220 boss 250 to bottom offset, with convenient the first pawl face 210 and the second pawl face 220 is applied acting force.The joint face of the first pawl face 210 and the second pawl face 220 is upwards arched upward form the boss of nature, make boss and the first pawl face 210 and the second pawl face 220 into a single integrated structure, be convenient to moulding, and in repeatedly pushing, also be not easy damage.
In a further embodiment, the first pawl face 210, the second pawl face 220, first supporting surface 230 and second supporting surface 240 can be in the same plane.When pushing the first pawl face 210 and the second pawl face 220 downwards, first supporting surface 230 and second supporting surface 240 can come off its button bit from the first pawl face 210 and the second pawl face 220 naturally with CD jack-up.Perhaps the first pawl face 210 and the second pawl face 220 are in the same plane, and first supporting surface 230 and plane, second supporting surface, 240 place are higher than the first pawl face 210 and plane, the second pawl face, 220 place.When pushing the first pawl face 210 and the second pawl face 220 downwards, first supporting surface 230 and second supporting surface 240 can come off its button bit from the first pawl face 210 and the second pawl face 220 naturally with CD jack-up.Test findings proves under above two kinds of schemes and all can smoothly CD be taken out.
In a further embodiment, first block and second block that are centrosymmetric with described first button bit 211 and second button bit 221 also can be set on first supporting surface 240 and second supporting surface 250, to make things convenient for CD to center on two button bits and two blocks Rotating with Uniform on stationary installation, prevent damaged compact disk.
During use, can be directly with cd center hole secured in alignment device, the downward press polish dish of exerting oneself a little makes on its button bit that is buckled in the first pawl face 210 and the second pawl face 220, and can rotate freely on stationary installation and not damage around button bit.When need taking out, available middle finger is pushed boss, makes the first pawl face 210 and the second pawl face 220 to bottom offset, and under the effect of the power that makes progress of first supporting surface 230 and second supporting surface 240, cd center hole can come off from button bit gently, thereby ejects.Unclamp middle finger this moment, and need not go CD is transferred to again.
The utility model is by the supporting surface on the employing reinforcement reinforcing CD-fixing device, and symmetrical supporting surface is set to a plane.When pressing the paw face, CD can be under the effect of first supporting surface and second supporting surface, the ejection that comes off automatically from the button bit of the first pawl face and the second pawl face, thus take out CD easily, CD is not damaged.Because the dynamics of pushing that needs is less, the pawl face on the optical disk cartridge stationary installation also is not easy to damage, and has prolonged the serviceable life of optical disk cartridge simultaneously.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
