[0002] Currently, small laser marking machines project lasers onto the workpiece through a laser head to form the desired patterns or other designs on the workpiece surface. To prevent accidents and laser injuries during operation, many laser marking machines are equipped with protective covers. However, since these covers are generally made of opaque metal, it is inconvenient to observe the working process in real time. Therefore, many manufacturers have added windows or transparent elements to the protective covers, but these methods are more complex and costly. Summary of the Invention

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 5 As shown.

[0025] Example 1: See Figures 1 to 5A protective cover includes a U-shaped cover body 10 and a transparent body 5. The cover body 10 includes a main body 2 located in the middle and side body parts 1 located on both sides. A window 3 is opened in the middle of the main body 2. Vertical reinforcing blocks 6 are respectively connected to the two sides of the inner side of the main body 2. The two vertical reinforcing blocks 6 are respectively located on both sides of the window 3. A lower horizontal reinforcing block 7 is provided between the two vertical reinforcing blocks 6. The upper end surface of the lower horizontal reinforcing block 7 is lower than or flush with the lower end surface of the window 3. At least one of the two vertical reinforcing blocks 6 is connected to a side L-shaped clamping block 8. One end of the side L-shaped clamping block 8 is connected to the back of the vertical reinforcing block 6, and the other end of the side L-shaped clamping block 8 extends toward the window 3. A gap is formed between the end surface of the other end and the back of the main body 2. The lower end of the transparent body 5 abuts against the lower horizontal reinforcing block 7. The left and right ends of the transparent body 5 abut against the back of the two sides of the window 3, and the transparent body 5 abuts against the side L-shaped clamping block 8.

[0026] This technical solution improves upon existing technology in the installation of the transparent body 5. The transparent body 5 can be made of various materials such as plastic, glass, and resin, which are existing technologies and will not be elaborated further. During installation, two vertical reinforcing blocks 6 and one horizontal reinforcing block form a U-shaped space with an open top, simultaneously strengthening the main body 2. The transparent body 5 is inserted from the top of the U-shaped space and abuts against the back of the main body 2. To prevent the transparent body 5 from tipping over, in this embodiment, one of the vertical reinforcing blocks 6 on both sides is connected to a side L-shaped clamping block 8, one end of which abuts against the transparent body 5. Alternatively, side L-shaped clamping blocks 8 can be connected to both vertical reinforcing blocks 6, with the left and right sides of the transparent body 5 being clamped by the side L-shaped clamping blocks 8 and the main body 2 respectively. The upper surface of the transparent body 5 can be higher than or flush with the upper surface of the window 3. In this embodiment, the upper surface of the transparent body 5 is higher than the upper surface of the window 3, resulting in a simple overall structure and quick installation.

[0027] See Figure 5 The upper back of the main body 2 is connected to an upper horizontal reinforcing block 4, which is located above the window 3 and abuts against the upper end of the transparent body 5.

[0028] When in use, if the upper part of the transparent body 5 is not restricted, the transparent body 5 will shake when the protective cover moves up and down, and sometimes it may even make abnormal noises, which is very unpleasant to the user. In order to avoid this phenomenon, this embodiment provides an upper horizontal reinforcing block 4 at the upper part of the back of the main body 2. The upper and lower sides of the transparent body 5 are clamped by the upper horizontal reinforcing block 4 and the lower horizontal reinforcing block 7, thereby effectively preventing the transparent body 5 from shaking.

[0029] See Figure 4The upper horizontal reinforcing block 4 is connected to an upper L-shaped clamping block 12. The upper end of the upper L-shaped clamping block 12 is connected to the upper horizontal reinforcing block 4, and the lower end of the upper L-shaped clamping block 12 abuts against the transparent body 5.

[0030] To further reinforce the transparent body 5, in this embodiment, an upper L-shaped clamping block 12 is connected to the upper horizontal reinforcing block 4. The upper L-shaped clamping block 12 and the main body 2 clamp the upper end of the transparent body 5.

[0031] Preferably, the lower horizontal reinforcing block 7 is connected to a lower L-shaped clamping block 15, the lower end of the lower L-shaped clamping block 15 is connected to the lower horizontal reinforcing block 7, and the upper end of the lower L-shaped clamping block 15 abuts against the transparent body 5.

[0032] The lower L-shaped clamping block 15 cooperates with the main body 2 to clamp the lower end of the transparent body 5, and then cooperates with the upper L-shaped clamping block 12 to clamp the upper and lower ends of the transparent body 5 respectively.

[0033] Furthermore, an upper flexible pad (not shown in the figure) is provided between the upper end of the transparent body 5 and the upper horizontal reinforcing block 4, and a lower flexible pad is provided between the lower end of the transparent body 5 and the lower horizontal reinforcing block 7.

[0034] The upper and lower flexible pads can be made of flexible materials such as rubber, sponge, and silicone. When the transparent body 5 moves up and down with the protective cover, the protective cover may frequently encounter foreign objects, causing it to stop abruptly or be stretched, resulting in the transparent body 5 vibrating vertically. To prevent rigid collisions between the transparent body 5 and the upper and lower horizontal reinforcing blocks 4 and 7 during vertical vibration, upper and lower flexible pads are provided to reduce the intensity of collisions and protect the transparent body 5. If necessary, side flexible pads can be provided on both sides of the transparent body 5.

[0035] See Figure 5 The upper L-shaped clamping block 12 and the lower L-shaped clamping block 15 are respectively provided with horizontal adjustment grooves 13 in the middle part, and the upper horizontal reinforcing block 4 and the lower horizontal reinforcing block 7 are respectively provided with connecting holes 14. The upper L-shaped clamping block 12 and the lower L-shaped clamping block 15 are respectively connected to the upper horizontal reinforcing block 4 and the lower horizontal reinforcing block 7 through connecting parts.

[0036] The connector can be a screw or bolt. The connecting hole 14 is a threaded hole. During installation, one end of the screw passes through the horizontal adjustment groove 13 and is threaded into the threaded hole. Initially, the screw is not tightened. At this time, the upper L-shaped clamp 12 or the lower L-shaped clamp 15 can be moved left or right. After adjusting the position of the upper L-shaped clamp 12 or the lower L-shaped clamp 15, the screw can be tightened to fix the upper L-shaped clamp 12 and the lower L-shaped clamp 15. The horizontal adjustment groove 13 is provided to adjust the position of the upper L-shaped clamp 12 and the lower L-shaped clamp 15.

[0037] See Figure 4 , Figure 5The side L-shaped clamping block 8 has a vertical adjustment groove 9 in the middle, and the vertical reinforcing block 6 has a side connection hole 11. The side L-shaped clamping block 8 is connected to the vertical reinforcing block 6 through a connector.

[0038] To facilitate the adjustment of the side L-shaped clamp 8, this embodiment provides a vertical adjustment groove 9 in the middle of the side L-shaped clamp 8 to facilitate the up and down adjustment of the L-shaped clamp; in use, the connecting part can be a bolt or screw; the side connecting hole 11 is a threaded hole; one end of the connecting part passes through the vertical adjustment groove 9 and extends into the side connecting hole 11.

[0039] Example 2: A laser marking machine includes a laser marking body 20, and the laser marking body 20 is connected to the above-mentioned protective cover.

[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
