[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] See also Figure 1 and Figure 2 The utility model provides a technical solution: a DVD core with an auxiliary pressing structure, comprising: a frame 1 and a DVD optical head 4, a disc rack 2 is slidably mounted on the bottom of the frame 1, a core frame 3 is mounted on the top of the frame 1, and the DVD optical head 4 is mounted in the middle of the core frame 3;

[0025] A bracket 5 is installed on the inner wall of the movement frame 3, and a motor 6 is installed on the top of the bracket 5. The output end of the motor 6 is connected to the screw 7 through a coupling, and a connecting frame 8 is installed on the outside of the screw 7. Guide columns 9 are connected between the four sides of the connecting frame 8 and the through holes of the bracket 5. A pressure plate 10 is installed on the bottom of the connecting frame 8. The movement frame 3 and the bracket 5 are an integrated structure, the bracket 5 is an arc-shaped structure, and the guide column 9 is installed on the top of the connecting frame 8.

[0026] During specific implementation, the DVD movement with an auxiliary pressing structure can place the disc on the disc rack 2 when it is necessary to press the disc, and then push the disc rack 2 to the bottom of the movement rack 3 through the rack 1. When the disc rack 2 moves to the bottom of the movement rack 3, the motor 6 can be started, so that the motor 6 drives the bottom screw rod 7 to rotate through the coupling. Since the screw rod 7 and the connecting frame 8 are threadedly connected, and a guide column 9 is installed on the top of the connecting frame 8, and the other end of the guide column 9 is connected to the through hole of the bracket 5, the guide column 9 guides the connecting frame 8 by the guide column 9, so that the screw rod 7 drives the connecting frame 8 to move downward when rotating. A pressure plate 10 is installed at the bottom of the connecting frame 8, and the downward movement of the connecting frame 8 will drive the pressure plate 10 to move downward. At this time, the pressure plate 10 can press the disc on the disc rack 2, thereby preventing the disc from moving during use and increasing the stability of the disc.

[0027] See Figure 2 、 Figure 4and Figure 5 It can be seen that when the CD is moved to the bottom of the movement frame 3, the motor 6 can be used to drive the screw rod 7 to rotate. When the screw rod 7 rotates, it will cooperate with the guide column 9 to drive the connecting frame 8 and the pressure plate 10 to move downward. The downward movement of the pressure plate 10 can press the CD on the CD rack 2, making it less likely for the CD to move.

[0028] A clamping block 11 is installed on both sides of the movement frame 3, a wedge block 12 is provided on one side of the clamping block 11, an elastic block 13 is installed on one end of the wedge block 12, and an inserting block 14 is inserted at both ends of the clamping block 11. A connecting block 15 is installed on the outside of the inserting block 14, and a fixed block 16 is sleeved on the outside of the inserting block 14. A movable spring 17 is connected between the connecting block 15 on the outside of the inserting block 14 and the fixed block 16. The fixed block 16 is installed in the groove of the frame 1, and the elastic block 13 is installed in the groove of the frame 1. One end of the inserting block 14 is a slope structure.

[0029] In a specific implementation, when the DVD movement with the auxiliary pressing structure needs to quickly install the movement frame 3 on the frame 1, it is only necessary to dock the clamping blocks 11 on both sides of the movement frame 3 with the grooves of the frame 1. At this time, the position of the clamping block 11 will be aligned with the wedge block 12 on one side of the elastic block 13. Since one end of the wedge block 12 is a sloped structure, when the movement frame 3 is installed, the clamping block 11 will squeeze the wedge block 12. The wedge block 12 will move to one side in cooperation with the elastic block 13 when squeezed. At this time, the elastic block 13 will bend. When the clamping block 11 moves along the groove of the frame 1 to the bottom of the wedge block 12, the wedge block 12 is no longer squeezed by the clamping block 11, and the elastic block 13 will reset, thereby driving the wedge block 12 to move to the top of the clamping block 11.

[0030] At the same time, when the card block 11 is inserted into the groove of the frame 1, since the end of the inserting block 14 close to the card block 11 is a sloped structure, the card block 11 will also be squeezed by the inclined surface when it moves along the groove of the frame 1, so that the inserting block 14 drives the connecting block 15 to move. Since the fixing block 16 is installed in the groove of the frame 1, when the connecting block 15 moves with the inserting block 14, the movable spring 17 sleeved on the outer side of the inserting block 14 will be in a compressed state. When the card block 11 is completely moved into the groove of the frame 1, the inserting block 14 will move in the opposite direction under the resetting action of the movable spring 17 and be inserted into the groove of the card block 11. The card block 11 can be stably limited by the inserting block 14. At the same time, the top of the card block 11 is limited by the top wedge block 12, so that the core frame 3 can be more stably docked into the groove of the frame 1;

[0031] When the movement frame 3 needs to be disassembled, it is only necessary to pull the insert block 14 out of the groove of the block 11 so that the insert block 14 does not limit the block 11, and then pull the block 11 upward. Since one end of the block 11 is a sloped structure, the upward movement of the block 11 will squeeze the bottom of the wedge block 12, causing the wedge block 12 to move to one side again through the elastic block 13. At this time, the block 11 can be pulled upward along the groove of the frame 1, so that the movement frame 3 can be removed from the top of the frame 1.

[0032] See Figure 2 、 Figure 3 and Figure 6 It can be seen that when used again, the movement frame 3 can be quickly fixed on the frame 1 through the cooperation of the clamping block 11 and the wedge block 12 according to the use requirements, and with the cooperation of the insert block 14 and the movable spring 17, the movement frame 3 can be limited more stably.

[0033] To sum up: when the DVD movement with the auxiliary pressing structure is in use, the movement frame 3 can be installed on the top of the frame 1 through the clamping block 11 and the wedge block 12, and then the optical disc is placed on the optical disc rack 2, and the optical disc rack 2 is pushed to the bottom of the movement frame 3 through the slide groove at the bottom of the frame 1. At this time, the motor 6 and the screw rod 7 drive the connecting frame 8 and the pressure plate 10 to press the optical disc, thereby preventing the optical disc from moving at will. Finally, the data on the optical disc can be read and scanned by the DVD optical head 4. This is the use feature of the DVD movement with the auxiliary pressing structure. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
