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 protective cover for a CNC machine tool, including a protective cover body 1. The protective cover body 1 has two adjustment slots 2 inside. A protective door 3 is slidably connected inside the adjustment slots 2. A handle 4 is fixedly connected to the front end of the protective door 3. Adjustment boxes 5 are fixedly connected to both sides of the front end of the protective cover body 1. A control plate 6 is slidably connected inside the adjustment box 5. A through slot 7 is opened on the side of the adjustment box 5 near the protective door 3. An insert block 8 is fixedly connected to the side of the control plate 6 near the protective door 3. A straight groove 9 is opened at the front end of the protective door 3. Several slots 10 are opened at the bottom end of the straight groove 9. When the operator pushes the control plate 6 into the adjustment box 5, the control plate 6 moves the insert block 8, releasing the insert block 8 from its limit position with the slot 10. The operator moves the protective door 3 to the left, closing the protective door 3, thereby preventing metal chips from flying during CNC machine tool operation and protecting the operator from injury during operation.

[0022] Reference Figure 4 As shown in this embodiment: both sides of the top of the adjustment box 5 are fixedly connected to a storage spring 11. The bottom end of the storage spring 11 is fixedly connected to the top of the control plate 6. When the operator pushes the control plate 6 into the adjustment box 5, the control plate 6 compresses the storage spring 11 to store force, and drives the plug 8 to release the limit between itself and the slot 10. When the operator releases the control plate 6, the storage spring 11 quickly returns to its original state under the action of compression and storage, pushes the control plate 6 to move outward, so that the plug 8 re-contacts the slot 10 and returns to the limit state. This design not only ensures that the protective cover can be quickly closed when needed, but also provides additional safety protection to prevent iron filings from flying in case of accidents.

[0023] Reference Figure 4 and Figure 5 As shown, in this embodiment: the size of the insert 8 is adapted to the size of the slot 10, and the surface of the insert 8 is inserted into the interior of the slot 10. By adapting the size of the insert 8 to the size of the slot 10, a seamless fit is achieved between the outer edge of the insert 8 and the inner wall of the slot 10. This precise matching of sizes enhances the bonding force between the insert 8 and the slot 10 components, effectively improving the stability of the overall structure. This design simplifies the limiting process and improves the limiting efficiency of the device.

[0024] Reference Figure 4As shown in this embodiment: sliding grooves 12 are provided on both sides of the inside of the adjustment box 5, and sliders 13 are fixedly connected to both sides of the control plate 6. The surface of the slider 13 is slidably connected to the inside of the sliding groove 12. When the operator moves the control plate 6, the control plate 6 drives the slider 13 to slide inside the sliding groove 12. Through the above setting, the sliding connection between the slider 13 and the sliding groove 12 not only reduces frictional resistance, but also significantly improves the flexibility and smoothness of operation. This design makes the control plate 6 more stable during movement and avoids jamming caused by excessive friction.

[0025] Reference Figure 3 As shown in this embodiment: a return spring 14 is fixedly connected to the side of the adjustment groove 2 away from the protective door 3, and a push block 15 is fixedly connected to the side of the return spring 14 close to the protective door 3. With the arrangement of the return spring 14 and the push block 15, when the operator moves the protective door 3 into the adjustment groove 2, the protective door 3 pushes the push block 15 to compress and store force on the return spring 14. When the operator releases the limit of the protective door 3, the protective door 3 is quickly pushed to close under the action of the rebound force of the return spring 14, thereby achieving the effect of rapid adjustment.

[0026] Reference Figure 3 As shown in this embodiment: sliding grooves 16 are provided at both ends of the adjustment groove 2, and sliding blocks 17 are fixedly connected to both sides of the protective door 3. The surface of the sliding block 17 is slidably connected to the inside of the sliding groove 16. When the operator moves the protective door 3, the protective door 3 drives the sliding block 17 to slide inside the sliding groove 16. Through the above settings, the sliding block 17 and the sliding groove 16 adopt a sliding contact design. Wear-resistant materials are used to reduce friction loss. When the operator moves, the protective door 3 pulls the sliding block 17 to slide smoothly in the sliding groove 16, ensuring the smoothness of the movement process and reducing the occurrence of jamming.

[0027] Reference Figure 3 As shown in this embodiment: a viewing window 18 is installed inside the protective door 3. With the viewing window 18 installed inside the protective door 3, the internal working status can be displayed in real time, which is convenient for operators to monitor and adjust, improving the convenience and safety of operation. The viewing window 18 is made of high light transmittance material to ensure the clarity of vision, and the internal situation can be accurately observed even in a dimly lit environment.

[0028] Working principle: The operator pushes the control plate 6 into the adjustment box 5, causing the control plate 6 to move the insert block 8 and release the limit between the insert block 8 and the slot 10. The operator moves the protective door 3 to the left, closing the protective door 3 to prevent iron filings from flying during CNC machine operation and protect the operator from injury. When the operator pushes the control plate 6 into the adjustment box 5, the control plate 6 compresses the storage spring 11 to store force, causing the insert block 8 to release the limit between it and the slot 10. When the operator releases the control plate 6, the storage spring 11 quickly returns to its original state under the action of compression and storage, pushing the control plate 6 outward, allowing the insert block 8 to release the limit between it and the slot 10. Block 8 re-engages with slot 10, returning to its limit position. This design not only ensures the protective cover can close quickly when needed but also provides additional safety by preventing metal filings from flying in case of accidents. The size of block 8 is matched to that of slot 10, achieving a seamless fit between the outer edge of block 8 and the inner wall of slot 10. This precise dimensional matching enhances the bonding force between the block 8 and slot 10 components, effectively improving the stability of the overall structure. This design simplifies the limit process and improves the limit efficiency of the device. When the operator moves control plate 6, control plate 6 drives slider 13 to slide inside the slide groove 12. Through the above settings, slider 1... The sliding connection between the control panel 6 and the slide 12 not only reduces frictional resistance but also significantly improves the flexibility and smoothness of operation. This design allows the control panel 6 to move more smoothly, avoiding jamming caused by excessive friction. With the return spring 14 and push block 15, when the operator moves the protective door 3 into the adjusting groove 2, the protective door 3 pushes the push block 15 to compress and store force on the return spring 14. When the operator releases the limit of the protective door 3, the return spring 14 quickly pushes the protective door 3 to close, thus achieving rapid adjustment. When the operator moves the protective door 3, the protective door 3 drives the sliding block 17 to slide... The sliding block 17 slides inside the sliding groove 16. With the above-mentioned settings, a sliding contact design is adopted between the sliding block 17 and the sliding groove 16. Wear-resistant materials are used to reduce friction loss. When the operator moves, the protective door 3 pulls the sliding block 17 to slide smoothly in the sliding groove 16, ensuring the smoothness of the movement process and reducing the occurrence of jamming. The protective door 3 is equipped with a viewing window 18, which can display the internal working status in real time, making it convenient for the operator to monitor and adjust, improving the convenience and safety of operation. The viewing window 18 is made of high light transmittance material to ensure the clarity of vision, and the internal situation can be accurately observed even in low light environments.
