[Prior art]

 Many of the optical disk storage cases currently used support the optical disk by a center support base. For example, in Chinese Patent Application No. 00262204, the optical disk contact surface of the center support pedestal is designed to be very small, so that the optical disk can easily tilt in the case, and if careless, damage the surface of the optical disk data area. At the same time, the rigidity of the support pedestal is insufficient, so that the optical disk easily detaches from the support pedestal under the action of excessive pushing pressure, which affects the acoustic effect and the image quality.

[0003]

[Problems to be solved by the invention]

 The purpose of the present invention is to improve the central support pedestal structure, reduce the push button pressure, increase the rigidity of the support pedestal and install a small circular ring on the basis of Chinese Patent 00026204 to provide a non-data area in the center of the optical disc. It is to expand the support surface of.

[0004]

[Means for Solving the Problems]

 The object of the present invention is realized by the following technology. Regarding the optical disk storage case, the case back is connected to the case bottom surface and the case cover surface, respectively, and the case bottom surface, the case back, and the case cover surface are closed to form an optical disk storage case. An optical disk support pedestal is installed on the inner surface of the bottom of the case. The optical disk support pedestal is connected to an elastic bridge composed of a button, an elastic small fan-shaped surface, a disk lock piece, etc. by a connection surface, and supports the bottom of the case. A small circular ring is installed on the outer periphery of the pedestal.

The diameter of the small circular ring described in the present invention is slightly smaller than the diameter of the non-data area at the center of the optical disk, and is vertically set on the bottom of the case. The vertical height of the small circular ring is large on the bottom of the case. It has the same height as the arc-shaped shoulder installed on the fan-shaped surface and shares the same surface.

[0006] The upper part of the pedestal core of the support pedestal described in the present invention has a ring-shaped core neck formed by a pair of rigid disk protection pieces and a pair of elastic disk lock pieces for each stage. The height of the disc protection piece is slightly higher than the height of the disc lock piece and button.

The vertical height of the small circular ring described in the present invention is the same as that of the inner circular ring of the large peripheral circular toothed ring, the circular arc-shaped support shoulder, and the like, and the optical disk shares the same height. It constitutes a support unit.

[0008] The three radiation lines having a radiation point at the center of the sector on the bottom surface of the case described in the present invention are connected stepwise to the outwardly extending reinforcing ribs and the small circular ring in the case. A rigid center support unit is formed, and the height of the extension reinforcing rib is slightly lower than the height of the small circular ring.

The removal of the optical disk is simple, reliable, safe and durable.

[0012]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. As shown in the figure, in the optical disk storage case of the present invention, the case back 13 is connected to the case bottom surface 12 and the case cover surface 11, respectively, and the case bottom surface 12, the case back 13 and the case cover surface 11 are respectively connected. Are closed to form an optical disk storage case, and an optical disk support pedestal 18 is installed on the inner surface of the case bottom surface 12. The optical disk support pedestal 18 has a button 21, an elastic small fan-shaped surface 15, and a disk clock. A piece 20 is included, the three of which form an elastic bridge by the connecting surface 15D and the concave groove 28. The button 21 is a flat-headed cylindrical button, and the bottom surface of the button 21 is connected to a small fan-shaped surface 15 symmetrical about a pair of optical disc support pedestal cores as a single-piece, one-piece elastic bridge surface. Are connected to the bridge pier 15A on the taper surface, and extend to the bottom of the small circular ring 26. A disk lock piece 20 is installed on the elastic small fan-shaped surface 15. On the disk lock piece 20, a disk lock blade 20A is installed.

The optical disk support pedestal 18 also includes a rigidly supported large fan-shaped surface 16, which is interconnected with the bottom surface 12 step by step through a rigid ramp 16 C and a small circular ring 26. The small circular ring 26 is perpendicular to the bottom plate and is connected to the bottom plate. An arc-shaped support shoulder 17 and a disk protection piece 19 are provided on the rigid support surface 16. At the top of the pedestal core, a ring-shaped core neck is formed stepwise by a pair of rigid disk protection pieces 19 and a pair of elastic disk lock pieces 20. The diameter slightly exceeds the diameter of the optical disk, but is slightly smaller than the diameter of the center hole of the optical disk. The disk protection piece 19 and the disk lock piece 20 protrude as a rigid surface and an elastic bridge surface, and form stepwise rings. I have. The disk protection piece 19 is connected vertically near the center of the large sector surface, and the vertical height of the disk protection piece 19 is slightly higher than the height of the disk lock piece 20. The small circular ring 26 installed outside the pedestal is concentric with the arc-shaped shoulder 17 on the rigid support surface and the center of the sector, and the small circular ring 26 is the arc-shaped shoulder 17 on the rigid support surface and the case bottom 12. The upper convex support has the same height as the shoulder 12D and shares the same plane.

The optical disk support pedestal 18 also includes three radial reinforcing ribs installed on the back surface of the case bottom surface 12, with the center of the fan on the rigidly supported large fan surface 16 as a radiation point, Three radial shapes 16B are formed as reinforcing ribs 27 extending toward the rigid slope 16C on the inner surface of the bottom of the case, and are interconnected with the rigid slope 16C and the small circular ring 26, respectively. are doing. The reinforcing rib 27 of the small circular ring and the radial shape 16B have the same height and share the same plane.

At the center of the back 13 of the case, a long protruding arc-shaped stop plate 13A is installed, and its role is to reinforce the rigidity of the back of the case and to protect the deformation of the optical disk protection case. To fulfill.

In the present invention, a flaky elastic bridge surface is provided in which the bottom surface of the flat-head cylindrical button 21 and a small fan-shaped surface symmetrical about a pair of pedestal cores are connected in a straight line by a concave groove 28. Both ends of the bridge surface are interconnected with the tapered bridge pier 15A. When a pressure is applied to the bridge surface, the bridge surface is elastically deformed downward to form a concave arc shape, and the concave groove 28 at the center of the bridge and the pier 15A are directed toward the center under the radial pressure. Tilt. When the pressure on the bridge surface is released, the bridge surface has an elastic force that returns upward, and the bridge surface also has a radial centrifugal force that returns both ends of the pier to its original position. The bridge surface returns quickly and accurately. At the same time, the force is also transmitted to the concave groove 28, and the disc lock blade 20A and the button on the disc lock piece 20 return to the original quickly and accurately.

An independently installed center button 21 is installed vertically in the center of the bridge surface, and an arc-shaped disc lock piece 20 symmetrical to the button 21 and provided with an expansion gap is provided vertically on both sides of the center of the bridge. It is installed in. When pressure is applied to the button 21, the pressure is transmitted from the bottom of the button 21 to the concave groove 28 on both sides of the center of the bridge and the small fan-shaped bridge surface. A symmetric elastic deformation potential energy is generated about the point, and a pair of concave grooves 28 interconnected with the bridge surface, the disk lock piece 20 and the disk lock blade 20A at the top thereof are formed on the bridge surface. As a result of the deformation, it is uniformly displaced inward in the radial direction and downward in the axial direction. The diameter of the disk lock blade 20A is smaller than the diameter of the center hole of the optical disk, and the center hole of the optical disk is separated from the core neck and the disk lock blade 20A upward by an axial method. And is lifted by the core pedestal. The provision of the concave groove 28 allows the center button 21 to achieve the effect of simple, comfortable, and safe under the situation where the application of the pressure by the finger changes little.

On the rigid large fan-shaped slope of the disk protection piece, three radiations formed along the base and center line of the fan with the center of the fan as a radiation point extend to the large fan-shaped slope, and the small circular ring 26 and The reinforcing ribs 27 are connected to each other to form reinforcing ribs 27 for each stage. The center of the small circular ring 26 and the sector is concentric, and the diameter of the radially outer edge is slightly smaller than the diameter of the non-data area of the center hole of the optical disk, and the small circular ring 26, the large circular ring shoulder-shaped surface 12D, the rigidity The three large shoulder surface arc-shaped shoulders 17 have the same height and share the same plane, enhance the support of the non-data area of the center hole of the optical disc, and apply pressure to the button even if pressure is applied to the button. Do not deform the optical disk by positioning it on the same plane from beginning to end.

The relative outer diameter of the pair of arc-shaped disk protection pieces in the radial direction is larger than the outer diameter of the neck of the arc-shaped disk lock piece, slightly smaller than the diameter of the center hole of the optical disk, and the height of the disk protection piece is small. The height of the button slightly exceeds the natural height of the button, and the rigid disk protective piece exerts an inductive positioning action with respect to the optical disk. Even if an unexpected pressure is applied to the button with the case closed, the optical disk is supported. It is responsible for protecting them from leaving.

The structure of the small circular ring 26 below the core pedestal and the internal reinforcing ribs 27 reinforces the strength of the entire pedestal core and prevents deformation, and the front and rear surfaces of the non-data area in the center hole of the optical disc are formed. It is stored statically so as not to be affected by any pressure in the axial and radial directions, and at the same time, the entire structural components of the support base are kept at the designed standard positions for a long period of time, and no permanent deformation occurs.

In the present invention, when storing the optical disk, when the peripheral edge 25A of the optical disk center hole is aligned with the disk protection piece 19A, the two disk lock pieces 20 and the disk lock blades 20A thereon, the disk protection piece By the direction guidance of 19A, the disc lock blade 20A supports the symmetrical peripheral edge 25A on both sides of the center hole of the optical disc, and the optical disc temporarily assumes an aerial suspension state. When the optical disk is pressed lightly with an appropriate pressure, the two disk lock blades 20A receive a pressing force from the peripheral edge of the optical disk center hole which is directed downward in a uniform axial direction, and the pressure is applied to the disk lock piece 20, the concave groove. 28 and the elastic bridge surface 15C, the bridge surface 15C gradually assumes a concave arcuate shape, and when the passing of the two disk lock blades 20A is smaller than the diameter of the optical disk center hole 25A, the straight elastic bridge surface is formed. The degree of the concave surface inclined toward the center of 15C approaches the maximum value. At this time, the peripheral edge 25A of the optical disk center hole is moved downward by passing through the disk lock blade 20A by the pressure of the finger, and the non-data area on the bottom surface of the optical disk is simultaneously a rigid large sector arcuate support shoulder. 17A, contact the small circular ring 26 and the circular ring shoulder surface 12C in the concave edge of the large circular ring and the arcuate convex supporting shoulder 12D on the outer periphery. At the same time, the elastic potential energy of the pier 15A and the elastic bridge surface 15C starts to be released, and the concave groove 28, the disc lock piece 20, and the disk clock blade 20A are all returned to the original state promptly, and the disk lock piece 20, the disk clock blade are restored. The radial return of 20A stops the peripheral edge 25A on the center hole of the optical disk and meshes with each other, so that the non-data area surface at the center of the optical disk and the non-data area surface at the outer peripheral edge of the optical disk are uniformly symmetrical in rigid arc shape. It is positioned on the shoulder 17A, on the small circular ring 26, on the large circular ring concave edge shoulder 12C, and on the outer peripheral arc-shaped convex support shoulder 12D.

The three radiations 16A of the back reinforcing ribs of the large fan-shaped surface 16 extend to the inside of the small circular ring 26 toward the rigid inclined surface 16C, and the inner reinforcing ribs 27 connected to each other are respectively formed on the bottom surface. It strengthens the external force resistance strength, and provides a robust support function, a function to prevent deformation of the center pedestal, and a protective function to prevent the optical disk from being deformed by high pressure. At the same time, the small circular ring 26, the large circular ring concave edge shoulder 12C, and the outer circular arc convex support shoulder 12D appropriately support the non-data area 25 at the center of the optical disk and the outer edge 25B of the optical disk, respectively, and cooperate with the case. The optical disc is balancedly positioned on the support pedestal 18 to support the optical disc therein.

Since the height of the button 21 and the disk lock piece 20 is slightly lower than the height of the disk protection piece 19, the rigid disk protection piece 19 receives an external force and protects the button 21 from malfunction due to the external force. After that, the lid surface 11 is closed. At this time, the arc-shaped disk crimping tongue piece 11C on the inner surface of the lid and the elliptical stop plate 13A on the back 13 of the case are displaced along with the lid surface 11, and the case is displaced. Closed to the bottom surface 12, the lower surface periphery 25C of the optical disk 25 is limited in position within the large circular ring so as to be symmetrical. The stopper spring plate 13A not only limits the movement of the optical disk and restricts the movement of the attached manual, but also increases the rigidity of the case back, and allows the storage case to receive even greater pressure during transportation and transportation. Protects optical disks so that they are not damaged by factors such as pressure or heavy pressure.

When removing the optical disk, when the user presses the button 21 lightly with a finger, pressure concentrates on the button 21, and the pressure is uniformly transmitted to the concave groove 28 and the elastic bridge 15 C. Since the surface 15C is the same in size and receives a downward acting force in the opposite axial direction, the bridge surface 15C gradually exhibits a concave surface, and the two disk lock pieces 20 and the disk lock blades thereon. 20A contracts radially toward the center and axially downward under the action of the light torsional force of the concave groove 28. The three radiations 16A and 16B of the back reinforcing ribs of the two large fan-shaped surfaces 16 extend outward to the bottom surface 12 and are interconnected with the small circular ring 26 on the bottom surface to form a rigid support base. The optical disc is deformed on the support base by the action force of the elastic bridge in order to resist the influence of the pressure of the elastic bridge and to support the non-data area at the center of the robust optical disc. Never.

When the distance between the two disk lock blades 20A falls below the diameter of the optical disk center hole 25A due to the pressure of the button 21, the optical disk center hole 25A releases the frictional force of the disk lock blade 20A and removes the optical disk. Move up in the axial direction. At this time, the concave surface of the elastic bridge 15C approaches the maximum value, and the arc-shaped shoulder 17A and the small circular ring 26 on the rigid large sector surface share the same surface to limit the downward displacement of the optical disk. As a result, the pressure on the button is released, and the disc lock blade 20A takes the initiative and returns outward in the radial direction. Since the top layer of the disc lock blade 20A supports the peripheral edge of the lower surface of the optical disc center hole 25A, the entire optical disc is axially driven by the direction of the disc protection piece 19 under the action of the elastic bridge 15. The optical disk can be quickly returned upward and flipped onto the support base 18, so that the optical disk can be easily taken out.

[Effect of the invention]

 Compared with the existing technology, the present invention has the following improvements and advantages. 1. The installation of the small circular ring enhances the rigidity of the entire core pedestal, and achieves a more stable, safe and reliable effect. 2. A single concave groove is designed at the interconnection between the elastic bridge and the button, and the connection surface is thinner and thinner, so that the button pressure decreases, the return elastic force increases, and the optical disk Extraction is easier. 3. Since the disc protection piece is slightly higher than the height of the disc lock piece, it effectively prevents pressure from outside the casing lid on the core pedestal, preventing the optical disc center hole from detaching from the support pedestal, The optical disk is effectively protected from detaching from the support base. 4. The three radiation reinforcing ribs on the bottom of the case extend into the case and interconnect with the small circular ring. The core pedestal is more robust and robust, so the optical disk in the case is deformed. It is effectively protected from being damaged. At the same time, the two large fan-shaped surfaces of the core pedestal are restricted from being inclined and deformed toward the core under the action of external force.
