Optical discs are used to store various types of data, such as documents, pictures, videos, audio, etc., and can be used as backup media for computer data.

[0003] In the comparative case, patent application number CN112530468B, the present invention discloses a fully automatic optical disc storage device, comprising: a frame, a rotating cage type optical disc storage mechanism comprising: a central axis, an optical disc storage box, an upper mounting plate and a lower mounting plate; the upper mounting plate and the lower mounting plate are respectively fixed to the top and bottom ends of the interior of the frame; the two ends of the central axis are rotatably connected to the upper mounting plate and the lower mounting plate respectively; there are multiple optical disc storage boxes, which are arranged in a stacked manner between the upper mounting plate and the lower mounting plate; a manipulator lifting mechanism comprising: an optical disc grabbing manipulator, a lead screw, a slider, and a driving assembly; the surface of the lead screw is rotatably connected to the slider; the optical disc grabbing manipulator is fixedly connected to the slider; there are multiple optical drives, which are fixed to the interior of the frame in a stacked arrangement; and the optical disc cartridge moving mechanism is fixedly connected to the frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1.

[0018] 4. The present invention can push the cabinet body and cooperate with the universal wheel to achieve overall movement through the setting of the moving component, and the universal wheel cooperates with the bracket to improve the support of the cabinet body, so that the load on the universal wheel during the movement of the cabinet body will not be too large, resulting in increased friction resistance and difficulty in movement.

[0019] 5. The present invention provides a buffer mechanism so that the placement plate can preferentially contact the sponge pad to reduce the impact when it is reset backward. The sponge pad is squeezed and deformed by force, causing deformation of the rubber plate. The slightly higher strength of the rubber plate allows it to deform to a certain extent and absorb kinetic energy, completing the buffering and slowly returning to its original state. It can be used repeatedly to absorb energy. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, the present invention provides an optical disc storage device for efficiently reading data, comprising: The cabinet body 1 has a frame 2 fixedly connected to the top and bottom of the inner side of the cabinet body 1, a hollow plate 3 fixedly connected to the top and bottom of the back end of the cabinet body 1, and a storage mechanism 4 slidably connected to the inner side of the frame 2; The storage mechanism 4 includes a slide plate 41, a placement plate 42, a groove disk 43 and a handle 44. The slide plate 41 is slidably connected to the inner side of the frame 2, the placement plate 42 is fixedly connected to the inner side of the slide plate 41, the top of the placement plate 42 is fixedly connected to the groove disk 43, the inner cavity of the groove disk 43 contains a data optical disc, the front end of the placement plate 42 is fixedly connected to the handle 44, and the left and right sides of the back end of the inner wall of the hollow plate 3 are fixedly connected to the reset mechanism 5.

[0024] refer to Figure 3 The reset mechanism 5 includes an extension rod 51, a hollow sleeve 52 and a spring 53. The left and right sides of the back end of the inner wall of the hollow plate 3 are fixedly connected with the extension rod 51. The front end of the extension rod 51 passes through the interior of the placement plate 42. The surface of the extension rod 51 and the back end of the placement plate 42 are movably connected with the hollow sleeve 52. The surface of the extension rod 51 is sleeved with a spring 53. The front and back ends of the spring 53 are fixedly connected to the back end of the hollow sleeve 52 and the front end of the hollow plate 3 respectively. The four corners of the top of the placement plate 42 are fixedly installed with protective mechanisms 6.

[0025] As a technical optimization solution of the present invention, through the setting of the reset mechanism 5, the hollow sleeve 52 can move along with the placement plate 42, and the hollow sleeve 52 moves along the extension rod 51, wherein the movement of the hollow sleeve 52 stretches the spring 53, and the elastic kinetic energy of the spring 53 is stored, which facilitates the reset of the hollow sleeve 52, avoids the user from repeatedly pushing and pulling, and saves physical strength.

[0026] refer to Figure 6 The protective mechanism 6 includes a bearing 61, a rotating shaft 62, an acrylic plate 63 and a magnet 64. The four corners of the top of the placement plate 42 are fixedly installed with bearings 61. The inner cavity of the bearing 61 is movably connected to the rotating shaft 62. The surface of the rotating shaft 62 is fixedly sleeved with an acrylic plate 63. The end of the acrylic plate 63 away from the rotating shaft 62 covers the surface of the groove disk 43. The inner side of the surface of the acrylic plate 63 is fixedly connected with a magnet 64. The four corners of the bottom of the cabinet 1 are fixedly connected with the moving component 7.

[0027] As a technical optimization solution of the present invention, through the setting of the protective mechanism 6, the acrylic plate 63 can be manually turned clockwise, and the acrylic plate 63 drives the rotating shaft 62 to rotate around the bearing 61 until the acrylic plate 63 covers the surface of the groove disk 43. The acrylic plates 63 close to each other cooperate with the magnet 64 to achieve magnetic fixation based on the principle of opposite charges attracting and like charges repelling, so that the acrylic plate 63 covers the groove disk 43 to protect the optical disc inside, thereby isolating the optical disc from contact with the external environment and avoiding contamination of the optical disc by dust and impurities.

[0028] refer to Figure 5The moving component 7 includes a bracket 71 and a universal wheel 72. The four corners of the bottom of the cabinet 1 are fixedly connected to the bracket 71. The bottom of the bracket 71 is fixedly installed with a universal wheel 72. The bottom of the universal wheel 72 is in contact with the ground. The surface of the extension rod 51 is laterally fixedly connected to the inside of the hollow plate 3 with a buffer mechanism 8.

[0029] As a technical optimization solution of the present invention, through the setting of the moving component 7, the universal wheel 72 can rotate to cooperate with the bracket 71 to carry the cabinet 1 as a whole to move, which is convenient for users to carry and avoid the cabinet 1 as a whole being too heavy to be carried.

[0030] refer to Figure 4 The buffer mechanism 8 includes a horizontal plate 81, a rubber plate 82 and a sponge pad 83. The surface of the extension rod 51 is located inside the hollow plate 3 and is laterally fixedly connected to the horizontal plate 81. The front end of the horizontal plate 81 is fixedly connected to the rubber plate 82. The front end of the rubber plate 82 passes through the front end of the hollow plate 3 and is fixedly connected to the sponge pad 83.

[0031] As a technical optimization solution of the present invention, the buffer mechanism 8 is provided so that the placement plate 42 can preferentially contact the sponge pad 83 after being reset. The sponge pad 83 absorbs energy and deforms and cooperates with the slightly stronger hardness of the rubber plate 82 to absorb kinetic energy, thereby reducing the impact of the reset kinetic energy of the placement plate 42 on the optical disc and protecting the stability of the internal optical disc.

[0032] refer to Figure 3 The left and right sides of the back end of the cabinet 1 are fixedly connected with reinforcement blocks 9, and the top of the reinforcement block 9 is fixedly connected to the bottom of the hollow plate 3.

[0033] As a technical optimization solution of the present invention, the provision of the reinforcing block 9 can assist the hollow slab 3 in working and at the same time play a reinforcing role, thereby avoiding the hollow slab 3 from breaking when subjected to external collision.

[0034] refer to Figure 3 A slide rail 10 is provided on the inner side of the frame 2 and corresponds to the position of the slide plate 41 , and the slide rail 10 is used in conjunction with the slide plate 41 .

[0035] As a technical optimization solution of the present invention, the slide rail 10 can enable the slide plate 41 to move back and forth inside the frame 2, and at the same time play a limiting role, thereby avoiding the slide plate 41 from offsetting during movement.

[0036] refer to Figure 1 The surface of the handle 44 is provided with anti-slip grooves, and the handle 44 is used in conjunction with the anti-slip grooves.

[0037] As a technical optimization solution of the present invention, the provision of the handle 44 can increase the frictional resistance of the handle 44 , thereby preventing the handle 44 from slipping when the user holds it in their hand.

[0038] The working principle and use process of the present invention are as follows: when in use, the cabinet body 1 is pushed to rotate with the universal wheel 72 to move the whole body. The universal wheel 72 cooperates with the bracket 71 to improve the bearing capacity of the cabinet body 1. When the cabinet body 1 moves to the required position, data can be transmitted between different devices and locations. Then the operator holds the handle 44 and pulls it forward. The handle 44 moves forward, driving the placement plate 42 and the groove disk 43 to move along. The placement plate 42 moves forward, driving the slide plate 41 and the hollow sleeve 52 to move along. The slide plate 41 moves stably along the slide rail 10 inside the frame 2. When the placement plate 42 drives the slide plate 41 and the hollow sleeve 52 to move to the front end, the pulling stops, and the hollow sleeve 52 moves stably forward along the extension rod 51 and stretches the spring 53. The spring 53 stretches to store elastic kinetic energy. At this time, the acrylic plate 63 is manually flipped counterclockwise. The rotation of the acrylic plate 63 drives the rotating shaft 62 to rotate and separate from each other around the bearing 61. The acrylic plate 63 separates to expose the groove disk. 43, then the operator holds the CD to take out or store it in the groove disk 43, and after storing the CD, the acrylic plate 63 is rotated clockwise. The acrylic plates 63 rotate close to each other and cover the surface of the groove disk 43. The close acrylic plates 63 cooperate with the magnet 64 to be magnetically fixed according to the principle of opposite charges attracting and like charges repelling. The acrylic plate 63 covers the surface of the groove disk 43 to isolate the CD from the external environment and achieve a protective effect. Finally, the handle 44 is released. The handle 44 is relieved of force. At this time, the spring 53 actively pulls the hollow sleeve 52 backward to reset. The hollow sleeve 52 moves backward to drive the placement plate 42 and the groove disk 43 to be stored back into the interior of the cabinet 1 as a whole. When the placement plate 42 is reset, it first contacts the sponge pad 83 to absorb kinetic energy. The sponge pad 83 deforms and cooperates with the slightly higher strength of the rubber plate 82 to produce deformation until the kinetic energy of the placement plate 42 is completely absorbed. The rubber plate 82 completes the energy absorption process to reduce the impact on the CD, thereby realizing layered storage of the CD to avoid stacking.

[0039] In summary, the optical disc storage device for efficiently reading data is used in conjunction with the cabinet 1, frame 2, hollow plate 3, storage mechanism 4, slide plate 41, placement plate 42, groove disk 43, handle 44 and reset mechanism 5. During operation, the handle 44 is held and pulled forward, and the handle 44 is driven by force to drive the placement plate 42 and groove disk 43 to move along, and the movement of the placement plate 42 drives the slide plate 41 to move stably along the inside of the frame 2. When the placement plate 42 and groove disk 43 move to the front end, the optical disc is placed at the center of the groove disk 43, and the handle 44 is pushed backward, so that the placement plate 42 and groove disk 43 are retracted into the interior of the cabinet 1 for storage, thereby realizing the function of quickly accessing the stored optical disc and realizing the layered storage of the optical disc to avoid stacking, solving the problem that most of the existing optical discs are stacked together during storage, which is easy to deform after long-term stacking and is not convenient for searching and taking. Secondly, the optical disc will be affected by the external environment during storage, causing dust particle contamination, resulting in damage to the protective layer and dye layer of the optical disc.
