[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model

[0036] Next, in conjunction with the attached Figure 1 to the attached Figure 10 and specific embodiments, the present utility model will be elaborated in detail

[0037] Refer to Figure 1 、 Figure 2, the present utility model provides a disc tray, which is used in cooperation with a disc storage device, an off-line disc case, a disc storage device, etc., to facilitate the user to simply replace the disc tray or store the disc off-line. When replacing, only the disc tray needs to be disassembled. The disc tray 1 of this application includes a tray body 11 and a mounting base 12. A disc storage cavity 110 is formed on the tray body 11 for accommodating the disc. It can be understood that the function of the disc storage cavity 110 is to store the disc. Since the disc is usually a circular disc, the corresponding disc storage cavity 110 can also be designed as a circular cavity. The circular cavity can further reduce the volume of the entire disc tray 1, but the shape of the disc storage cavity 110 is not limited to this; the mounting base 12 is connected to the outer wall of the tray body 11, and its height is lower than that of the tray body 11, which is convenient for stacking the disc trays 1 up and down. An elastic connection part 13 is arranged on the side of the mounting base 12 facing away from the disc storage cavity 110. The mounting base 12 is detachably connected to the rotating bracket 21 or inside the off-line box body 31 through the elastic connection part 13. This application sets the disc tray 1 into a detachable structure, which can be separately disassembled from the disc storage device and installed in the off-line box, or disassembled from the off-line box and installed in the disc storage device. At the same time, it is more convenient to replace the damaged disc tray. The overall structure of this application is simple, can be used in cooperation with multiple devices, and has a wide range of applications.

[0038] It should be noted that the elastic connection part 13 can be understood as any structure with elastic deformation ability, or any structure that can be deformed. Its main function is to install the disc tray 1 in the disc storage device or the off-line box without demolition, or disassemble the disc tray 1 from the disc storage device or the off-line box. For example: the elastic connection part 13 can be an elastomer, an elastic sheet, etc., but not limited to this.

[0039] In some embodiments, the mounting base 12 extends outward in a flared manner along the direction away from the tray body 11. The purpose of setting this structure is to cooperate with the rotating bracket 21. When the disc tray 1 is used in cooperation with the disc storage device, since the disc storage device needs to rotate in the disc storage device, therefore, the position closer to the rotation point is designed in a flared manner to ensure the smooth rotation of the disc storage device.

[0040] In some embodiments, a notch 120 penetrating the upper surface is provided on the mounting base 12; one end of the elastic connection portion 13 is connected to the side wall of the notch 120, and the other end is suspended in the notch 120, and the elastic connection portion 13 protrudes from the upper surface of the mounting base 12. Setting one end of the elastic connection portion 13 in the notch 120 provides a space for the elastic connection portion 13 to deform downward; when removing the disc tray 1, pressing the elastic connection portion 13 downward can cause it to deform downward, so that the upper surface of the elastic connection portion 13 is not higher than the upper surface of the mounting base 12, thereby realizing the removal of the disc tray 1; when installing the disc tray 1, after the disc tray 1 is pushed into the specified position, the elastic connection portion 13 bounces upward without external force to realize the clamping with other structures.

[0041] In other embodiments, a notch 120 penetrating the upper surface is provided on the mounting base 12; the elastic connection portion 13 includes a spring piece provided at the notch 120 and a protrusion (not shown in the figure) located on the spring piece, and the protrusion moves vertically back and forth with the spring piece, thereby realizing the clamping or release of the clamping with other structures.

[0042] In this embodiment, to save materials, the mounting base 12 is designed as an inverted concave structure, including a top wall 121 and two side walls 122. The notch 120 is provided on the top wall 121 and penetrates the top wall. Reinforcing ribs 123 are provided at intervals at the lower end of the top wall 121 to improve the strength of the mounting base 12. At the corresponding position in the inner cavity between the reinforcing ribs 123 and the two side walls 122, a corresponding limiting structure 217 (as Figure 10 shown) is designed on the rotating bracket 21. The limiting structure 217 is arranged between two adjacent reinforcing ribs 123 and is in close contact with the side surfaces of the two reinforcing ribs, which can further strengthen the matching strength between the mounting base 12 and the rotating bracket 21. In a preferred embodiment, the mounting base 12 includes 3 reinforcing ribs 123 arranged at intervals. Correspondingly, two limiting structures 217 are provided on the rotating bracket 21. The 3 reinforcing ribs 123 form two limiting grooves, and the limiting structures 217 are inserted into the limiting grooves, thereby realizing the matching strength between the mounting base 12 and the rotating bracket 21. However, this is not limited thereto. In other embodiments, the number of the reinforcing ribs 123 and the limiting structures 217 can be set according to actual needs.

[0043] In some embodiments, a label 14 is further provided on the outer wall surface of the tray body 11. The label 14 is circumferentially spaced from the mounting base 12. Optionally, the label 14 is a two-dimensional code label or an RFID label. The label 14 is used for the identity identification of the disc, which is convenient for online positioning and identification, and is also convenient for offline management after going offline. Preferably, the label 14 is arranged on the surface opposite to the mounting base 12, which is more convenient for users to observe the position of the two-dimensional code.

[0044] In a preferred embodiment, the elastic connection portion is made of a metal material or a plastic material.

[0045] See also Figures 3 to 6 The utility model also provides a disk storage device 2, including a rotating bracket 21, on which a tray matching groove 211 and a limiting card groove 212 connected to the tray matching groove 211 are opened, and the limiting card groove 212 penetrates the rotating bracket 21 upward, and the above-mentioned optical disc tray 1 is inserted into the tray matching groove 211 through the mounting seat 12, and after being inserted into place, it is clamped in the limiting card groove 212 through the elastic connecting part 13, and the tray matching groove 211 is adapted to the shape of the mounting seat 12, that is, the mounting seat 12 is completely matched with the tray matching groove 211, so as to realize the stable connection between the optical disc tray 1 and the rotating bracket 21 and avoid shaking. The tray matching groove 211 has an entrance end, and the mounting seat 12 enters the tray matching groove 211 from the entrance end. When the elastic connecting portion 13 is also in the tray matching groove 211, the upper wall of the tray matching groove 211 will apply downward pressure to the elastic connecting portion 13, causing the elastic connecting portion 13 to deform downward. When the elastic connecting portion 13 moves into the limiting card slot 212, the elastic connecting portion 13 resets upward and enters the limiting card slot 212 to achieve a snap connection, thereby installing the optical disc tray 1 on the rotating bracket 21. The rotating bracket 21 can be set in the optical disc storage device and cannot be removed during the use of the optical disc storage device. When the optical disc tray 1 needs to be replaced, it only needs to be turned out of the optical disc storage device, and by pressing the elastic connecting portion 13 to make it lower than the tray matching groove 21, the optical disc tray 1 can be pulled out of the rotating bracket 21.

[0046] In some embodiments, a shaft hole 213 is provided on the rotating bracket 21 on the side away from the optical disc tray 1, and an elastic positioning structure 22 is provided on the rotating bracket 21, and one end of the elastic positioning structure 22 extends into the shaft hole 213. A central axis 23 is provided in the shaft hole 213, and at least one positioning groove 231 is provided on the outer surface of the central axis 23. One end of the elastic positioning structure 22 can be pressed against the positioning groove 213 to achieve the positioning of the optical disc tray 1. Specifically, when the optical disc tray 1 is installed on the rotating bracket 21, the disk storage device is not positioned, and the elastic positioning structure 22 does not enter any positioning groove 213 at this time. When the rotating bracket 21 is rotated by a certain angle with the central axis 23 as the rotating axis, the disk storage device completes the positioning, and the elastic positioning structure 22 resets inward and enters the positioning groove 213, so that the disk storage device can be accurately stuck in the set position. In this embodiment, the specific composition of the elastic positioning structure 22 is not limited, as long as the above-mentioned function can be achieved, it belongs to the protection scope of this application.

[0047] It is worth noting that the central axis 23 of the present application can be a vertical axis directly fixed in the optical disk storage device; it can also be a central axis that cooperates with the vertical axis in the optical disk storage device. For example, a special-shaped hole (square hole, multi-deformed hole, elliptical hole, etc.) is provided on the central axis, and the vertical axis is a special-shaped axis that cooperates with the special-shaped hole. Through the provision of the special-shaped hole and the special-shaped axis, it is achieved that when the central axis is assembled on the vertical axis, the two do not rotate relative to each other; for another example, at least two vertical axes are provided, and correspondingly, at least two through holes are provided in the central axis. The central axis is installed in the vertical axis through the through holes, so that the rotating bracket 21 can only rotate around the central axis but not around the vertical axis, thereby avoiding the situation where positioning cannot be performed.

[0048] In some embodiments, a mounting cavity 214 is provided between the rotating shaft hole 213 and the tray matching groove 211, and a first through hole 215 is provided on the first side wall of the mounting cavity 214. In other words, the inner wall of the rotating shaft hole 213 and the first side wall of the mounting cavity 214 are of the same structure. The elastic positioning structure 22 is provided in the mounting cavity 214, and one end thereof passes through the first through hole 215 and enters the rotating shaft hole 213. The inner diameter of the first through hole 215 needs to be designed according to the elastic positioning structure 22, highlighting its guiding and stabilizing effect on the elastic positioning structure 22. In the case of no positioning, one end of the elastic positioning structure 22 is always located in the first through hole 215. After positioning, one end of the elastic positioning structure 22 extends from the first through hole 215 into the rotating shaft hole 213, and then enters the positioning groove 231. It can be seen that the first through hole 215 guides the extension and contraction of the elastic positioning structure 22, and its size can make one end of the elastic positioning structure 22 move stably in the first through hole 215.

[0049] In some embodiments, a second through hole 216 opposite to and coaxial with the first through hole 215 is provided on the second side wall of the mounting cavity 214; the elastic positioning structure 22 includes a stop pin shaft 221 inserted in the first through hole 215 and the second through hole 216, an elastic member 222 and a retaining spring 223 sleeved on the stop pin shaft 221, that is, one end of the stop pin shaft 221 is inserted in the first through hole 215, and the other end of the stop pin shaft 221 is inserted in the second through hole 216, and the elastic member 222 and the retaining spring 223 are sleeved on the stop pin shaft 221. The spring 223 is located between the first through hole 215 and the second through hole 216. The stop pin 221 is provided with an annular groove, in which the spring 223 is clamped. The annular groove is located at one end of the first through hole 216. One end of the elastic member 222 abuts against the spring 223, and the other end abuts against the second side wall of the installation cavity 214. The spring 223 can limit the movement path of the stop pin 221 in the first through hole 215 to prevent the stop pin 221 from being separated from the first through hole 215. The elastic member 222 in this embodiment is preferably a spring.

[0050] See also Figure 7 , Figure 8, the present utility model also provides an optical disc offline box, which includes an offline box body 31. An optical disc tray receiving groove is provided inside the offline box body 31. The shape of the optical disc tray receiving groove is adapted to the shape of the optical disc tray 1, and the height of the optical disc tray receiving groove is substantially the same as the height of the tray body 11. The optical disc tray receiving groove has an inlet end 311. A clamping groove 312 is provided on one side of the optical disc tray receiving groove away from the inlet end. The above-mentioned optical disc tray 1 is inserted into the optical disc tray receiving groove from the inlet end 311. After being inserted in place, the elastic connecting portion 13 pops up upward and is clamped in the clamping groove 312 to form a complete optical disc offline box. When it needs to be opened, the optical disc tray 1 can be pulled out by pressing the elastic connecting portion 13 downward.

[0051] In some preferred embodiments, a sunk groove 313 is provided on the offline box body 31. The clamping groove 312 communicates with the bottom of the sunk groove 313, and a soft rubber cushion block 314 is installed in the sunk groove 313. During the use of the offline box, it is necessary to ensure the cleanliness inside it. Therefore, the offline box needs to be in a sealed state. In this application, in order to ensure the sealing of the offline box, the height of the optical disc tray receiving groove is the same as the height of the optical disc tray 1, and the shape of the inlet end 311 of the optical disc tray receiving groove is the same as the side wall shape of the tray body 11. When the optical disc tray 1 is installed in the offline box body 31, the side wall of the tray body 11 just closes the inlet end 311 of the optical disc tray receiving groove, thereby ensuring the cleanliness during the offline storage process. In addition, the position of the clamping groove 312 of the offline box body 31 is another opening. A sunk groove 313 is provided at this position, and a soft rubber cushion block 314 matching the size of the sunk groove 313 is installed in the sunk groove 313. The lower end of the soft rubber cushion block 314 just abuts against the upper end of the elastic connecting portion 13. When the soft rubber cushion block 314 is pressed downward, the elastic connecting portion 13 can be driven to move downward, so that it disengages from the clamping groove 312. Optionally, mounting holes are respectively provided at both ends of the bottom of the sunk groove 313 corresponding to the clamping groove 312. The lower end of the soft rubber cushion block 314 is provided with mounting feet corresponding to the mounting holes, and the lower end of the mounting feet is provided with limiting blocks. The soft rubber cushion block 314 is fixedly installed by clamping the limiting blocks at the bottom of the clamping groove 312, so that the optical disc is in a sealed state during the offline storage process.

[0052] The present utility model also provides an optical disc storage device, which includes a tray and multiple vertical shafts arranged on the tray. At least one of the above-mentioned disc storage devices 2 is installed on the vertical shafts. Refer to Figure 9 , when multiple disc storage devices 2 are installed on the vertical shafts, the disc storage devices 2 are stacked together. At this time, it is necessary to ensure that the gap between adjacent optical disc trays is greater than 0 to avoid friction when adjacent optical disc trays rotate, and the gap between adjacent optical discs needs to be less than the thickness of one optical disc to prevent the optical discs in the optical disc tray 1 from jumping out of the gap.

[0053] The optical disc storage device of the present application adopts all the technical solutions of all the embodiments of the above-mentioned disc storage 2 and disc tray 1. Therefore, it has at least all the beneficial effects brought by the technical solutions of the embodiments of the above-mentioned disc storage 2 and disc tray 1, which will not be elaborated one by one here.
