[0002] In the design of electronic devices or precision instruments, shielding is a common component used to isolate electromagnetic interference (EMI) or radio frequency interference (RFI) to ensure signal stability and equipment reliability.
[0003] Traditional noise-reducing shields typically use a fixed-size structure. However, most existing shields are one-piece molded or fixed designs, and their width and size cannot be flexibly adjusted according to actual application requirements. If the shield cannot be expanded or contracted to adapt to a new spatial layout, it may lead to a decrease in shielding effect, or even require redesign and customization of a new shield, increasing production costs and time costs. Utility Model Content

Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a noise-reducing shielding cover, including a shielding cover body 1. Adjustment grooves 2 are provided on both sides of the shielding cover body 1. Side covers 3 are slidably connected inside the adjustment grooves 2. Adjustment boxes 4 are fixedly connected to both sides of the top of the shielding cover body 1. A straight groove 5 is provided at the bottom of the side cover 3. Several slots 6 are provided at the front end of the straight groove 5. A control groove 9 is provided inside the adjustment box 4. A through groove 7 is provided at the top of the control groove 9. A control block 11 is slidably connected inside the control groove 9. An insert block 8 is fixedly connected to the top of the control block 11. When an operator pushes the control block 11 into the control groove 9, the control block 11 moves the insert block 8, releasing the limit between the insert block 8 and the slot 6. Simultaneously, the limit of the side cover 3 is also released. The operator moves the side cover 3 to a suitable position and re-limits the insert block 8 and the slot 6, thereby achieving flexible size adjustment.
[0022] Reference Figure 2 As shown in this embodiment: the size of the insert 8 is adapted to the size of the slot 6, and the surface of the insert 8 is inserted into the interior of the slot 6. By adapting the size of the insert 8 to the size of the slot 6, the insert 8 can be stably engaged inside the slot 6, thereby limiting the position of the side cover 3, preventing the side cover 3 from shaking during use, and improving the stability of the side cover 3.
[0023] Reference Figure 4 As shown in this embodiment: a storage spring 10 is fixedly connected to the side of the control block 11 near the inside of the control groove 9, and the side of the storage spring 10 away from the control block 11 is fixedly connected to the inside of the control groove 9. When the operator pushes the control block 11 into the control groove 9, the control block 11 compresses the storage spring 10 to store force, and drives the insertion block 8 to release the limit between it and the slot 6. After the operator adjusts the appropriate position of the side cover 3, the operator releases the control block 11. Under the action of the rebound force of the storage spring 10, the control block 11 quickly resets, and drives the insertion block 8 to be inserted into the inside of the slot 6, thereby achieving a second limitation on the position of the side cover 3.
[0024] Reference Figure 3As shown in this embodiment: both ends of the adjustment groove 2 are provided with sliding grooves 12, and both ends of the side cover 3 are fixedly connected with sliders 13. The surface of the sliders 13 is slidably connected to the inside of the sliding grooves 12. When the operator moves the side cover 3 back and forth, the side cover 3 drives the sliders 13 to slide inside the sliding grooves 12. Through the above settings, the movement of the side cover 3 is more stable, the shaking is reduced, and the stability and practicality of the device are improved.
[0025] Reference Figure 5 As shown in this embodiment: a shrinkage column 14 is fixedly connected to the side of the adjustment groove 2 away from the side cover 3. A push block 16 is slidably connected inside the shrinkage column 14. A return spring 15 is fixedly connected to the side of the push block 16 near the inside of the shrinkage column 14. The side of the return spring 15 away from the push block 16 is fixedly connected to the inside of the shrinkage column 14. When the operator pushes the side cover 3 into the adjustment groove 2, the side cover 3 pushes the push block 16 to compress the return spring 15 to store force. When the operator releases the limit of the side cover 3, the push block 16 quickly resets under the action of the rebound force of the return spring 15, and drives the side cover 3 to return to the initial position stably.
[0026] Reference Figure 5 As shown in this embodiment: sliding grooves 17 are provided at both ends of the shrink column 14, and sliding blocks 18 are fixedly connected to both ends of the push block 16. The surface of the sliding block 18 is slidably connected to the inside of the sliding groove 17. When the operator moves the push block 16, the push block 16 drives the sliding block 18 to slide inside the sliding groove 17. Through the above settings, the movement of the push block 16 is more stable, effectively preventing the push block 16 from deviating or shaking during the movement, ensuring the accuracy and reliability of the operation. At the same time, the sliding connection design of the sliding block 18 inside the sliding groove 17 also reduces the frictional resistance during the movement, making the operation smoother and improving work efficiency.
[0027] Reference Figure 4 As shown in this embodiment: guide grooves 19 are provided on both sides of the control groove 9, and guide blocks 20 are fixedly connected to both sides of the control block 11. The surface of the guide block 20 is slidably connected to the inside of the guide groove 19. When the operator moves the control block 11, the control block 11 drives the guide block 20 to slide inside the guide groove 19. Through the above settings, the movement of the control block 11 is more stable, reducing the bumps during the movement and improving the stability and reliability of the overall structure.
[0028] Working principle: The operator pushes the control block 11 into the control slot 9. During this movement, the control block 11 moves the insert 8, releasing the limit between the insert 8 and the slot 6. Simultaneously, the limit of the side cover 3 is also released. The operator moves the side cover 3 to the appropriate position and re-limits the insert 8 and slot 6, thus achieving flexible size adjustment. By matching the size of the insert 8 with the size of the slot 6, the insert 8 can stably engage inside the slot 6, thereby limiting the position of the side cover 3 and preventing it from being used improperly. During the process, shaking occurs, improving the stability of the side cover 3. When the operator pushes the control block 11 into the control slot 9, the control block 11 compresses the storage spring 10 to store force, and drives the insert block 8 to release the limit between itself and the slot 6. After the operator adjusts the side cover 3 to the appropriate position, the operator releases the control block 11. Under the action of the rebound force of the storage spring 10, the control block 11 quickly resets, driving the insert block 8 to engage inside the slot 6, thus re-limiting the position of the side cover 3. When the operator moves the side cover 3 back and forth, the side cover 3 drives the slider 13 to move inside the slide groove 12. The sliding mechanism, through the above-mentioned design, makes the movement of the side cover 3 more stable, reduces swaying, and improves the stability and practicality of the device. When the operator pushes the side cover 3 into the adjustment groove 2, the side cover 3 pushes the push block 16 to compress the return spring 15 to store force. When the operator releases the limit of the side cover 3, under the action of the return spring 15, the push block 16 quickly resets, driving the side cover 3 to return to its initial position stably. When the operator operates the push block 16 to move, the push block 16 drives the sliding block 18 to slide inside the sliding groove 17. Through the above-mentioned design, the push block 16... The movement is more stable, effectively preventing the push block 16 from deviating or shaking during movement, ensuring the accuracy and reliability of the operation. At the same time, the sliding connection design of the sliding block 18 inside the sliding groove 17 also reduces the frictional resistance during movement, making the operation smoother and improving work efficiency. When the operator moves the control block 11, the control block 11 drives the guide block 20 to slide inside the guide groove 19. Through the above settings, the movement of the control block 11 is more stable, reducing the bumps during movement and improving the stability and reliability of the overall structure.
