Technical Field
[0001] The utility model relates to the technical field of DVD core frames, in particular to a DVD core frame with an anti-dislocation and offset structure. Background Art
[0002] A DVD player is a type of optical disc storage medium that is widely used to store and play video and audio data, and plays an important role in the fields of digital entertainment and home theater. The DVD movement frame is an important component of a DVD player. It mainly supports and fixes the various components of the movement to ensure the stability and reliability of the movement during playback. However, the existing DVD movement frame still has certain defects when used.
[0003] In the prior art, the DVD movement frame can provide stable support for various components in the movement. However, various faults are inevitable during the long-term use of the DVD movement frame, which may cause the tray inside the DVD movement frame to become misaligned during long-term use or disassembly, thereby causing offset, making it difficult for the tray to be stably fixed inside the DVD movement frame. Utility Model Content
[0004] The purpose of the utility model is to provide a DVD player frame with an anti-dislocation structure to solve the problem of misalignment of the tray inside the DVD player frame currently on the market as mentioned in the background art.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: A DVD movement frame with an anti-dislocation and offset structure, comprising: a frame body, a tray, a fixing seat, a guide rod, a movement slider, a gear drive motor and a circuit board, the inner surface of the frame body is installed with a tray, the surface of the tray is installed with a fixing seat, a guide rod is commonly connected between the two fixing seats, the outer side of the guide rod is slidably connected to the movement slider, the surface of the tray is respectively installed with a gear drive motor and a circuit board, a first fixing block is connected to the surface of the tray, the internal thread of the first fixing block is connected to a threaded knob, the end of the threaded knob is connected to a plug-in rod, a card slot is provided on the outer side of the plug-in rod, the surface of the frame body close to the first fixing block is connected to a second fixing block, the internal thread of the second fixing block is connected to a small threaded column, and the end of the small threaded column is connected to a semicircular card block.
[0006] Preferably, a plug-in hole matching the size of the plug-in rod is provided inside the second fixing block.
[0007] Preferably, a sliding structure is formed between the semicircular clamping block and the second fixed block.
[0008] Preferably, a mounting block is welded to the outer side of the end portion of the fixing seat, and a connecting block is connected to the outer side of the mounting block.
[0009] Preferably, a buffer block is slidably connected to the outer side of the guide rod, and a return spring is commonly connected between the buffer block and the inside of the mounting block.
[0010] Preferably, a guide column is connected to a side of the buffer block close to the connecting block, and a through hole is opened through the interior of the connecting block.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: the DVD movement frame with an anti-dislocation offset structure first places the tray on the inner side of the frame body, and then the plug-in rod at the end of the threaded knob passes through the first fixed block. When one end of the plug-in rod on the threaded knob is plugged into the inside of the second fixed block, the plug-in rod can slide between the second fixed block. When the movement slider slides to the maximum distance, the return spring is compressed to the maximum extent. During this process, the return spring can have a certain buffering effect on the movement slider, so that the movement slider can effectively absorb the vibration and impact generated by the movement components during operation, protecting the movement components from damage.
[0012] The first fixing block and the second fixing block are stably docked, so that the tray is not easily misaligned or offset inside the frame body, thereby ensuring that the DVD core frame can be used normally after disassembly and assembly.
[0013] 2. During the use of the DVD movement frame, the movement slider can slide along the guide rod. During the operation of the movement slider, certain vibrations and impacts will be generated, making the DVD movement susceptible to damage. When one end of the movement slider slides to the surface of the buffer block, the movement slider can squeeze the surface of the buffer block. When the buffer block is squeezed, it can slide along the guide rod. At the same time, the buffer block can squeeze the reset spring during the sliding process. When the reset spring is squeezed, it will be compressed. When the movement slider slides to the maximum distance, the reset spring is compressed to the maximum extent. During this process, the reset spring can have a certain buffering effect on the movement slider, so that the movement slider can effectively absorb the vibration and impact generated by the movement components during operation, protecting the movement components from damage.

DETAILED DESCRIPTION
[0018] 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.
[0019] See also Figure 1 and Figure 2It can be seen that the utility model provides a technical solution: a DVD core rack with an anti-displacement structure, comprising: a frame body 1, a tray 2, a fixing seat 3, a guide rod 4, a core slider 5, a gear drive motor 6 and a circuit board 7, the inner surface of the frame body 1 is mounted with the tray 2, the surface of the tray 2 is mounted with the fixing seat 3, the two fixing seats 3 are connected together with the guide rod 4, the outer side of the guide rod 4 is slidably connected with the core slider 5, the surface of the tray 2 is respectively mounted with a gear drive motor 6 and a circuit board 7, the first fixing block 8 is connected to the tray 2, the internal thread of the first fixing block 8 is connected to the threaded knob 9, the end of the threaded knob 9 is connected to the plug rod 10, the outer side of the plug rod 10 is provided with a card slot 11, the surface of the rack body 1 close to the first fixing block 8 is connected to the second fixing block 12, the internal thread of the second fixing block 12 is connected to a small threaded column 13, the end of the small threaded column 13 is connected to a semicircular card block 14, the interior of the second fixing block 12 is provided with a plug hole that matches the size of the plug rod 10, and a sliding structure is formed between the semicircular card block 14 and the second fixing block 12.
[0020] In specific implementation, the DVD core frame is installed inside the DVD player. Due to long-term use or disassembly, the tray 2 and the frame body 1 may be misaligned, thereby affecting the normal use of the DVD core frame. First, place the tray 2 inside the frame body 1, then pass the plug-in rod 10 at the end of the threaded knob 9 through the first fixed block 8, and rotate the threaded knob 9 forward. When the threaded knob 9 is rotated, it can slide through the first fixed block 8 in the direction close to the second fixed block 12, and when the threaded knob 9 is rotated, it can drive the plug-in rod 10 to rotate and move. When the plug-in rod 10 on the threaded knob 9 is rotated, the first fixed block 8 is screwed to the second fixed block 12. When one end of the plug-in rod 10 is inserted into the second fixing block 12, the plug-in rod 10 can slide between the second fixing block 12. When the end of the plug-in rod 10 cannot move further, the small threaded column 13 can be tightened. When the small threaded column 13 rotates, it can drive the semicircular block 14 to rotate and move in the direction close to the plug-in rod 10. When the end of the semicircular block 14 rotates and moves into the slot 11 on the plug-in rod 10, the semicircular block 14 can limit the position of the plug-in rod 10 and the threaded knob 9, so that the plug-in rod 10 and the threaded knob 9 are not easy to loosen, and at the same time, the tray 2 can be stably installed on the inner side of the rack body 1.
[0021] See Figure 1 and Figure 2 It can be seen that the first fixing block 8 and the second fixing block 12 are stably docked, so that the tray 2 is not easily misplaced or offset inside the frame body 1, thereby ensuring that the DVD core frame can be used normally after disassembly and assembly.
[0022] See Figure 1 and Figure 3It can be seen that a mounting block 15 is welded to the outer side of the end of the fixing seat 3, a connecting block 16 is connected to the outer side of the mounting block 15, a buffer block 17 is slidably connected to the outer side of the guide rod 4, a return spring 18 is commonly connected between the buffer block 17 and the inside of the mounting block 15, a guide column 19 is connected to the side of the buffer block 17 close to the connecting block 16, a through hole is opened through the inside of the connecting block 16, and the shape of the guide column 19 is L-shaped.
[0023] During specific implementation, when the DVD movement frame is in use, the movement slider 5 can slide along the guide rod 4. During operation, the movement slider 5 will generate certain vibrations and impacts, making the DVD movement susceptible to damage. The movement slider 5 can slide toward the direction close to the fixed seat 3 through the guide rod 4. When one end of the movement slider 5 slides to the surface of the buffer block 17, the movement slider 5 can squeeze the surface of the buffer block 17. When the buffer block 17 is squeezed, it can slide along the guide rod 4, and when the buffer block 17 slides, it can drive the guide column 19 to move. When the guide column 19 moves, it can slide with the connecting block 16. At the same time, during the sliding process, the buffer block 17 can squeeze the reset spring 18, and the reset spring 18 will be compressed when it is squeezed.
[0024] See Figure 1 and Figure 3 It can be seen that when the movement slider 5 slides to the maximum distance, the return spring 18 is compressed to the maximum extent. During this process, the return spring 18 can have a certain buffering effect on the movement slider 5, so that the movement slider 5 can effectively absorb the vibration and impact generated by the movement components during operation, and protect the movement components from damage.
[0025] To sum up, when using the DVD movement frame with an anti-displacement and offset structure, first place the tray 2 on the inner side of the frame body 1, then pass the connecting rod 10 at the end of the threaded knob 9 through the first fixed block 8, and rotate the threaded knob 9 forward. When the threaded knob 9 rotates, it can slide through the first fixed block 8 in the direction close to the second fixed block 12, and stably dock the first fixed block 8 and the second fixed block 12, so that the tray 2 is not easily displaced and offset on the inner side of the frame body 1, thereby ensuring that the DVD movement frame can be used normally after disassembly and assembly. The reset spring 18 can have a certain buffering effect on the movement slider 5, so that the movement slider 5 can effectively absorb the vibration and impact generated by the movement components during operation, and protect the movement components from damage.
