[0032] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0033] refer to Figure 1 and Figure 2 The first aspect of this utility model provides a sheet metal waterproof structure, which aims to achieve a tight connection and effective waterproofing between two panels through a specific structural design. The sheet metal waterproof structure includes a first plate 1 and a second plate 2. The first plate 1 includes a first panel 11 and a second panel 12. The second panel 12 is bent inward toward the first panel perpendicular to the first panel 11, and the first panel 11 and the second panel 12 form an L-shaped structure. The second panel 12 includes a third panel 21 and a partition structure. The partition structure includes a fourth panel 22, a fifth panel 23, and a sixth panel 24 connected in sequence. The third panel 21 is connected to the fourth panel 22, and the fourth panel 22, the fifth panel 23, and the sixth panel 24 are arranged around the inside of the first plate. Figure 3 (Circling clockwise in the middle), forming a semi-enclosed first sealing space.

[0034] With the first plate 1 and the second plate 2 connected, the first panel 11 and the third panel 21 are approximately collinear. The second panel 12 and the fourth panel 22 are tightly fitted together to prevent water from flowing out from the gap between them. The fifth panel 23 is parallel to the first panel 11, and the sixth panel 24 is perpendicular to the fifth panel 23. The gap between the second panel 12 and the fourth panel 22 is located within the first sealing space, and the sixth panel 24 is perpendicular to the first panel 11 and has a certain gap from it. This gap can be adjusted according to actual needs; the smaller the gap, the less water can enter the first sealing space, or the lower the probability of it. In a specific embodiment, the baffle structure is located inside the machine tool protective cover to prevent water from flowing out from the gap between the first plate 1 and the second plate 2, i.e., to prevent water from flowing out from the gap between the second panel 12 and the fourth panel 22. The baffle structure serves as the first waterproof barrier against water penetration. Both the first plate 1 and the second plate 2 are integrally formed panels. During the manufacturing process of these two plates, the panels are formed by bending the plates.

[0035] The sheet metal waterproof structure provided in this embodiment forms a tight connection and an effective waterproof barrier between the first plate 1 and the second plate 2. The second panel 12 is completely contained within the first sealing space and tightly adheres to the fourth panel 22, thereby effectively preventing moisture from seeping through the connection. Simultaneously, since the first plate 1 and the second plate 2 are integrally formed, the overall structure is more stable, improving the reliability and durability of the waterproof structure. This application, through the partition structure, enables the two plates to achieve a waterproof effect immediately after assembly, avoiding the use of adhesives in traditional methods and reducing the number of adhesive application steps during assembly; it also avoids the inconvenience of later maintenance caused by the use of adhesives.

[0036] In one specific implementation, reference is made to Figure 2 and Figure 3 A seventh panel 13, connected to the second panel 12, is added to the first panel 1, allowing the seventh panel 13 to fit tightly against the fifth panel 23. This further enhances the sealing and stability of the waterproof structure, effectively preventing water penetration. The seventh panel 13 is perpendicular to the second panel 12 and located within the first sealing space. The tight fit between the seventh panel 13 and the fifth panel 23 forms a second waterproof barrier, enhancing the waterproof effect. Through the sheet metal waterproof structure provided in this embodiment, a double waterproof barrier is formed between the first panel 1 and the second panel 2. The first waterproof barrier is provided by the first sealing space formed by the fourth panel 22, the fifth panel 23, and the sixth panel 24. The second waterproof barrier is formed by the tight fit between the seventh panel 13 and the fifth panel 23. This design significantly improves the sealing and stability of the waterproof structure, effectively preventing water penetration from the joints.

[0037] In one specific implementation, reference is made to Figure 2 and Figure 3 An eighth panel 14 and a ninth panel 15 are added to the first plate 1, so that the second panel 12, the eighth panel 14, the ninth panel 15, and the seventh panel 13 are sequentially bent and connected, and are all located within the first sealing space. Simultaneously, the eighth panel 14, the ninth panel 15, the fourth panel 22, and the fifth panel 23 enclose a rectangular second sealing space 3. The second sealing space 3 is a vertically continuous tunnel structure that allows liquid to flow. In actual operation, a small amount of water or water mist may enter through the gap between the fifth panel 23 and the seventh panel 13. The design of the second sealing space 3 allows water to flow out along the tunnel wall of the second sealing space 3 towards the tunnel entrance, thereby reducing the leakage of water or liquid from the gap between the second panel 12 and the fourth panel 22. Alternatively, during operation, some water mist may cool and form a water flow within the second sealing space 3, flowing out along the tunnel wall of the second sealing space 3 towards the tunnel entrance. This design of the second sealing space 3 further enhances the sealing and stability of the waterproof structure, effectively preventing water penetration and acting as a third waterproof barrier.

[0038] In one specific implementation, reference is made to Figure 2 and Figure 3 An L-shaped third panel 4 is added within the second sealing space 3, with one panel of the third panel 4 parallel to or tightly fitted to the eighth panel 14, and the other panel of the third panel 4 fixedly attached to the fourth panel 22. This design further enhances the sealing and stability of the waterproof structure, effectively preventing moisture from seeping from the second sealing space 3 through the gap between the second panel 12 and the fourth panel 22, thus improving the overall waterproof performance.

[0039] The L-shaped third plate 4 further enhances the sealing of the second sealing space 3, preventing moisture from seeping out from the connection between the first plate 1 and the second plate 2, thus forming a fourth waterproof barrier. This design significantly improves the sealing and stability of the waterproof structure, effectively preventing moisture from seeping in from various connections. At the same time, because each plate is integrally set or tightly connected, the overall structure is more stable, extending the service life of the waterproof structure.

[0040] In one specific implementation, reference is made to Figure 2 and Figure 3 A positioning structure is provided between the second panel 12 and the fourth panel 22. The positioning structure includes a protrusion 5 arranged vertically along the second panel 12 and a groove 6 arranged vertically along the fourth panel 22. The size and shape of the groove 6 match the protrusion 5 on the fourth panel 22. This positioning structure ensures accurate alignment of the second panel 12 and the fourth panel 22 during assembly, improving assembly precision and efficiency, while also enhancing the connection stability between them, further improving the overall performance of the waterproof structure.

[0041] The second panel 12 of the first plate 1 and the fourth panel 22 of the second plate 2 are tightly fitted together, with the protrusion 5 on the second panel 12 accurately aligned with the groove 6 on the fourth panel 22. Appropriate pressure is applied to insert the protrusion 5 into the groove 6, ensuring a tight fit. In addition to its guiding and positioning function, the positioning structure also provides a degree of anti-permeability effect.

[0042] In one specific implementation, reference is made to Figure 3 The sheet metal waterproof structure also includes a first fastening structure 7, which passes through the fifth panel 23 and the seventh panel 13. This first fastening structure 7 strengthens the connection between the first plate 1 and the second plate 2, improving the overall structural stability and waterproof performance. It also ensures a tighter fit between the fifth panel 23 and the seventh panel 13, facilitating waterproof penetration. According to design requirements, suitable fasteners are selected as the first fastening structure 7, such as bolts, screws, or rivets. The first fastening structure 7 is passed through holes in the seventh panel 13 and the fifth panel 23 and tightened, such as by tightening bolts, screws, or riveting, to ensure the connection strength between the first plate 1 and the second plate 2.

[0043] In one specific implementation, reference is made to Figure 3 To further enhance the stability and waterproof performance of the structure, a second fastening structure 8 is provided. This second fastening structure 8 passes through the fourth panel 22, the second sealing space 3, the ninth panel 15, and another panel of the third plate 4 to achieve a more reliable connection and seal. The second fastening structure 8 passes through the second sealing space 3, ensuring that it remains vertical within the second sealing space 3. Both the first fastening structure 7 and the second fastening structure 8 can be bolts.

[0044] The second fastening structure 8 passes through the second sealing space 3. Water vapor enters the second sealing space 3 through the gap between the second fastening structure 8 and the plate, and then flows out from its outlet along the inner wall of the second sealing space 3. This fastening position of the second fastening structure 8 serves to fasten the first plate 1 and the second plate 2, and further serves to prevent water seepage.

[0045] In one specific implementation, reference is made to Figure 4 The first plate 1 is bent towards the fifth panel 23 to form the tenth panel 16 and the eleventh panel 17. The eleventh panel 17 is parallel to the fifth panel 23. The tenth panel 16 is located between the first panel 11 and the eleventh panel 17, gradually decreasing in elevation. By bending the first plate 1, the eleventh panel 17 is brought closer to the fifth panel 23, and the channel between the eleventh panel 17 and the first panel 11 becomes narrower. The inclined tenth panel 16 facilitates the flow of water along the surface of the tenth panel 16 into the narrowed channel.

[0046] A second aspect of this utility model provides a protective cover for a machine tool, as shown in the reference. Figure 1 and Figure 2 The sheet metal waterproof structure described above is applied at the joints between the plates of the machine tool protective cover. The sheet metal waterproof structure of this application is applied to the machine tool protective cover, with the aforementioned waterproof structure installed at the joints between the protective cover plates. This waterproof structure improves the waterproof performance of the machine tool protective cover, preventing water from seeping out during machine tool processing. The use of the sheet metal waterproof structure facilitates the assembly of the machine tool protective cover; the plates can be directly assembled without the need for waterproof strips or adhesive structures for waterproofing.

[0047] In one specific implementation, reference is made to Figure 1 and Figure 2 The machine tool protective cover also includes a water collection tank 9, which is located at the bottom of the protective cover. The bottom outlet of the second sealing space 3 of the sheet metal waterproof structure is connected to the water collection tank 9. Water in the second sealing space 3 flows along its inner wall into the water collection tank 9 and is discharged from the machine tool through the water collection tank 9. The water collection tank 9 serves to collect and guide water.

[0048] A third aspect of this utility model provides a machine tool, including a base, and the machine tool also includes any of the above-mentioned sheet metal waterproof structure or protective cover of the machine tool, the sheet metal waterproof structure or protective cover being disposed on the base.

[0049] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
