[0022] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0023] Reference Figures 1-6As shown, this utility model provides a technical solution: a miniaturized video recorder motherboard suitable for compact spaces, including a mounting plate 1, a sliding plate 2 slidably connected to the upper surface of the mounting plate 1, a video recorder motherboard body 3 slidably connected to the upper surface of the sliding plate 2, a groove 4 opened on the upper surface of the sliding plate 2, a bidirectional threaded rod 5 rotatably connected inside the sliding plate 2, the bidirectional threaded rod 5 passing through the groove 4, two sliders 6 threadedly connected to the arc surface of the bidirectional threaded rod 5, the sliders 6 slidably connected to the inner wall of the groove 4, a U-shaped clamp 7 fixedly connected to the side of the two sliders 6 that are close to each other, the U-shaped clamp 7 abutting against one side of the video recorder motherboard body 3, a rotating shaft 8 fixedly connected to one end of the bidirectional threaded rod 5, the motherboard can be quickly clamped by the clamping mechanism composed of the bidirectional threaded rod 5, sliders 6 and U-shaped clamp 7, simplifying the installation process and preventing loosening;Meanwhile, during subsequent maintenance, it facilitates quick disassembly and adjustment of the main board, improving operational convenience and maintenance efficiency. This avoids problems such as easy stripping of screws during traditional screw installation and the inconvenience of finding tools for disassembly. The arc surface of the rotating shaft 8 has several slots 9, evenly distributed in a circular array on the arc surface of the rotating shaft 8. These slots 9 increase the friction of the arc surface of the rotating shaft 8, making it more stable for the operator when rotating the shaft 8. This facilitates precise and effortless driving of the bidirectional threaded rod 5, improving the convenience and controllability of clamping or releasing the main board. A U-shaped clamping pad 10 is fixedly connected to the inner wall of the U-shaped clamping plate 7. The U-shaped clamping pad 10 is made of silicone rubber, which provides elastic cushioning. Features: When clamped, it can deform to tightly fit the motherboard surface, avoiding hard contact that could scratch the motherboard or damage components due to compression. It also enhances friction to prevent the motherboard from sliding. Furthermore, the insulation of the silicone rubber isolates the clamping plate from direct contact with the motherboard circuitry, reducing the risk of short circuits. A ball bearing 11 is fixedly connected to the lower surface of the slider 6, and the ball bearing 11 slides against the bottom surface of the inner wall of the slide groove 4. The ball bearing 11 significantly reduces the friction of the slider 6 when sliding within the slide groove 4, making the slider 6 move more smoothly under the drive of the bidirectional threaded rod 5, reducing mechanical wear, and extending service life. Two fixing blocks 12 are fixedly connected to the upper surface of the mounting plate 1. Each fixing block 12 has a square opening on one side closest to it. A square groove has a fixed rod 13 fixedly connected to its inner wall. A circular ring block 19 is slidably connected to the arc surface of the fixed rod 13. The sides of the two circular ring blocks 19 closest to each other are fixedly connected to the slide plate 2. Circular grooves are provided on both sides of the slide plate 2. Springs 15 are fixedly connected to the inner walls of the circular grooves. Circular rods 16 are fixedly connected to the ends of the two springs 15 furthest from each other. The circular rods 16 are slidably connected to the inner walls of the circular grooves. Several circular holes 14 are provided on the sides of the two fixed blocks 12 closest to each other. The size of the circular rods 16 matches the size of the circular holes 14. By adjusting the position of the slide plate 2, the distance between the mainboard body 3 of the video recorder and the internal components can be adjusted, effectively avoiding the problem of tightly packed components. To address the issue of insufficient heat dissipation space, the heat dissipation area of ​​the motherboard is increased to accelerate heat dissipation and prevent overheating due to heat accumulation. A sliding rod 18 is slidably connected to the inner wall of the sliding hole 17. One end of the sliding rod 18 is fixedly connected to the round rod 16. By sliding the sliding rod 18 within the sliding hole 17, the sliding rod 18 can be manually moved to move the round rod 16 within the round groove. The compression spring 15 disengages or engages the round rod 16 with the round hole 14, facilitating the operator's adjustment of the position of the slide plate 2. The front end of the round rod 16 is arc-shaped. When the slide plate 2 moves to the appropriate position, the arc-shaped front end can be smoothly springed into the round hole 14 by the spring 15, reducing jamming, lowering installation resistance, and improving positioning efficiency.

[0024] Working Principle: When the VCR mainboard 3 needs to be installed on the slide plate 2, the VCR mainboard 3 is placed on the slide plate 2. By rotating the shaft 8, the bidirectional threaded rod 5, which is fixedly connected to the shaft 8, rotates. This rotation drives two sliders 6 to move towards or away from each other within the groove 4. As the sliders 6 move, the U-shaped clamp 7 fixed to one side moves accordingly until it comes into tight contact with both sides of the VCR mainboard 3, thus quickly clamping and fixing the VCR mainboard 3. During this process, the several grooves 9 on the arc surface of the shaft 8 increase the surface friction of the shaft 8, making it more stable for the operator to rotate the shaft 8. This allows for precise and effortless control of the rotation of the bidirectional threaded rod 5, facilitating adjustment of the clamping degree of the U-shaped clamp 7 on the mainboard. Meanwhile, the silicone rubber U-shaped pad 10 on the inner wall of the U-shaped clamp 7, with its own elastic buffering properties, deforms during the clamping process and fits tightly against the motherboard surface. This not only prevents the clamp from causing hard scratches or component compression damage to the motherboard, but also enhances friction and prevents the motherboard from sliding. In addition, the ball bearing 11 on the lower surface of the slider 6 slides and connects to the bottom surface of the inner wall of the slide groove 4, which significantly reduces the friction when the slider 6 slides, making the slider 6 move more smoothly under the drive of the bidirectional threaded rod 5, reducing mechanical wear, extending the service life of the entire structure, and making the operation of clamping the motherboard easier. When it is necessary to adjust the position of the main body 3 of the video recorder, manually move the slide bar 18. The slide bar 18 drives the round rod 16 to move in the round groove of the slide plate 2. The compression spring 15 makes the round rod 16 disengage from the round hole 14 on the fixing block 12, at which point the slide plate 2 can be moved freely. After the skateboard 2 moves to the appropriate position, the slide bar 18 is released. The elastic restoring force of the spring 15 pushes the round bar 16 into the corresponding round hole 14, achieving precise fixation of the skateboard 2 and preventing accidental slippage during use. The arc-shaped design at the front end of the round bar 16 allows it to automatically slide through the round hole 14 when the skateboard 2 moves, eliminating the need to manually press the round bar 16. This makes the movement of the skateboard 2 smoother, and once in position, it is more smoothly sprang into the round hole 14 by the spring 15, reducing jamming and improving positioning efficiency.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
