Description

The laser disc Storage Box

The utility model relates to a kind of laser disc Storage Box, the especially a kind of Storage Box that can protect laser disc to avoid damaging in various uses or storage and transport process.

Present various computer optical data CDs all have a garden shape central standard pilot hole; and the special device of being furnished with these CDs of kinds of protect packing miscellaneous stores CD; CD; optical data disks such as DVD compact disk generally store lot of data information; in the video disc rotation process, pass through a motion magnetic head from the transparent bottom reading of data of dish; information is divided into one or more magnetic tracks; magnetic track is covered by the top layer with protectiveness ultra-thin on the video disc; the method of dish face upper strata by silk-screen or labelled; general storage method can cause the scratch bottom, and causes because of disturbing the optical rail obliterated data.Owing to the protective seam of very thin about 20 micron thickness of scratch, cause deleting information simultaneously from the vapour phase metal level of about 0.1 micron thickness.At present, CD protecting Storage Box both domestic and external has the center support base of each style usually, does not contact arbitrary in data of optical disk holds the district, and the engagement cd center hole fastens CD; And the big garden that is provided with a balance CD external diameter contact portion is encircled.But the more difficult access CD that centre mount lock collar power is big causes the CD distortion, and what lock collar power was little can not support and protect CD again effectively, mostly also has protectiveness defective in various degree.

As U.S. Pat 5,944, No. 181, its center button is independently to have elastic partss such as button disc, the button dish wing to constitute a core print seat by three, and it has following weak point:

When 1. the user applies acting force to center button, easy clip finger, feel is uncomfortable;

2. if when taking out CD, finger acts on that power must be evenly distributed on the button, otherwise three button discs are because of discontinuity equalization, and the lock collar wing can not leave the center pit edge simultaneously, needs exert pressure inconvenient operation to the button of not dislocation once more;

3. when core print seat is deposited CD, need to apply bigger acting force and go to overcome shell fragment power on the shoulder shape face, and cross conference because of pressure sometimes spring support integral body is moved down CD, it is unreliable to pick and place the dish holding function.

4. cd centre's bore edges will bear axle pressure and the radial pull effect from centre mount, impels the long-term stressed easy deformation of CD.Equally, centre mount is subjected to the power of center hole for a long time, and each parts easily produces memory distortion, elastic break-down.

5. the weak point of Storage Box also be embodied in centre mount do not have prevention shaft to function.When Storage Box was in the close position, the former CD that is positioned on the centre mount because of the external force effect breaks away from the lock collar wing easily, caused CD to move in box, scratches the data field.Can not overcome CD is using, is carrying, is being subjected to the external force effect in the process such as transportation and the shortcoming of dislocating.Storage Box adopts the design of cantilever-type separate button, and processing ease fractures often.

U.S. Pat 5,788.068 disclosed a kind of Storage Boxes, its Storage Box core print seat support corresponding the snap lock disc and the lock collar wing by a symmetrical button and come the pinning center bore edges, and its shortcoming has:

1. be arranged on core print seat shell fragment supporting slice on every side and be higher than core print seat lock collar point, the data of optical disk district is subject to shell fragment and destroys.

When 2. depositing CD, need to apply bigger acting force to CD for overcoming shell fragment power user.It is unreliable to locate, and CD is subject to the acting force distortion.

3. be positioned at CD on the core print seat and will bear from the pulling force of the lock collar wing of center pit and the acting force that shell fragment axially makes progress and keep stable, CD is in upper and lower force-bearing situation on core print seat, and long-term storage is yielding.

4. because the lock collar sheet is in stress for a long time, the elastic force of each parts of core print seat can descend gradually, influences serviceable life.

5. CD in the Storage Box of closure state is subject to the external force extruding and breaks away from core print seat, the damage CD.

In sum, the present disc storage box that uses, the cd center hole edge is stressed easily when depositing, and lock collar power is unbalanced, and is yielding, unreliable.Do not reach the effect of excellent protection CD; more obvious 4 are: be subject to reacting force flexural deformation once in the CD taking-up process; another point is exactly that Storage Box very easily is being subjected to make CD break away from supporting base under the effect of external force extruding force; can not play the protective effect of reliable location; so that the CD that has mass data and information use, carry, transport, in the process such as carrying; because of scratch or wearing and tearing destroy tonequality and image effect, even cause information dropout, CD cancels.The 3rd, CD is subjected in storage radially, axial pressure, and is yielding, and the glue member also can be the Memorability distortion for a long time under the acting force of CD, loses effect.The 4th, some button is to be divided into more than two, easy clip finger etc.

The purpose of this utility model is to provide a kind of and can overcomes CD and using, carry, be subjected to the external force effect in the process such as transportation and the shortcoming of dislocating and damaging.

The utility model design has effect and the advantage of following uniqueness compared with prior art. 1, core print seat adopts the hard and soft segmented model design that is integrated, and take button as application point, concentrates the application of force, Keep strokes firm support. 2, one is centrosymmetric with button and links to each other with the little covering of the fan of elasticity and consists of the in-line elastic bridge, Take button as application point, the concave arc deformation potential takes place in in-line bridge floor center stressed, power by The diffusion of bridge mind-set two ends, and be delivered to the terminal point bridge pier. Two end of the bridge stress balances, a word slice bridge Face restores rapidly, and CD is because being subjected to the each access of balanced power effect undeformed. 3, the lock collar wing of two symmetries, two diameters are a bit larger tham cd center hole aperture, two under the natural situation Symmetrical lock collar sheet diameter is slightly less than protection plate sheet diameter, and protection plate sheet diameter is slightly less than again cd centre The aperture keeps the CD hole can not be subjected to any vertical, transverse pressure, freely deposits in storing process Put. Lock collar sheet diameter is less than the cd center hole diameter simultaneously, and radially return meshes again light rightly Center hole makes more Portable power saving of access CD. 4, a pair of big covering of the fan supporting base of rigidity that is centrosymmetric with button, it vertically places rigidity big The nearly fan of fan heart place protection plate sheet plays guide-localization and the effect of protection CD. 5, the big covering of the fan of rigidity is provided with the arc supporting fan that relatively increases, and is relative with outstanding elasticity bridge floor Potential can overcome axial downward pressure when getting dish, supports the CD equilibrant force, makes pressurized or button The time disc plane indeformable. 6, the big fan-shaped bearing-surface back side has by consisting of along fan base and fan end center line take the fan heart as exit point Article three, ray forms the rigidity bottom surface, in order to strengthening the supporting member rigidity, and when this partial component is stressed, Shape, size, position do not change. 7, the supporting base button flushes with the protection plate sheet, namely makes things convenient for the user to point and applies active force, prevents again Extraneous accidental destruction power makes the button misoperation, prevents the CD dislocation. 8, the level height of arc shoulder on substrate and the protection plate seat under the lock collar wing, under static situation all the time Maintenance makes the cd center hole front and rear surfaces not bear any axial pressure of core neck greater than disk thickness Power. Equally, the cd center hole that leaves on the core neck can not produce any reaction force to the core neck, The construction package of supporting base can remain on the standard design position for a long time, and is durable in use. 9, supporting base top forms a ring by a pair of rigidity protection plate sheet and the segmentation of a pair of snap lock disc The core neck, its protection plate sheet diameter is slightly larger than the lock collar sheet neck is slightly less than again the cd center hole diameter, Reduce the axial resistance of cd center hole when access, especially the diameter size of rigidity protection plate sheet is not Make the impact of any power, guarantee that the CD hole does not stress. 10, the interior circular arc diameter of great circle ring seat is slightly less than again the CD external diameter, and makes things convenient for the user from different angles Degree is picked up CD, also is fit to the mechanical packaging requirement.

Platen reed on the lid can attached folder detail file, and the arc pressing board sheet of box back can be limit Specification data processed displacement strengthens again box back of the body rigidity intensity, can also with the arc bullet of opening on the box position The property pressure dish tongue piece CD edge on the inner face large circle of the symmetrical spacing end when closed condition is closed in storage, The duplicate protection CD is firm location in box.
