[0025] Please see Figure 1 , Figure 3 and Figure 4The telescopic mechanism 4 includes a displacement groove 41. The outer wall of the displacement groove 41 is embedded and connected to the inner wall of the cover 2. A limit block 42 is provided on one side of the inner wall of the displacement groove 41. A through hole 43 is provided in the middle of one side of the displacement groove 41. An extension plate 44 is slidably connected to the inner wall of the displacement groove 41. Limit grooves 45 are opened through both sides of the extension plate 44. An adjustment hole 46 is opened in the middle of the inner wall of the extension plate 44. A bolt 47 is inserted into the inner wall of the through hole 43. One side of the inner wall of the displacement groove 41 is fixedly connected to both ends of the limit block 42. The middle of one side of the displacement groove 41 is connected through the outer wall of the through hole 43.

[0026] The outer wall of the displacement groove 41 is tightly connected to the inner wall of the cover 2 through an embedded connection, ensuring the stability and reliability of the entire structure. A limiting block 42 is provided on one side of the inner wall of the displacement groove 41. This limiting block 42 restricts the movement range of the extension plate 44 during expansion and contraction, preventing damage from excessive expansion and contraction. Furthermore, a through hole 43 is opened in the middle of one side of the displacement groove 41. The presence of this through hole 43 allows the bolt 47 to pass through the displacement groove 41.

Through the coordinated use of components such as the displacement groove 41, the limiting block 42, the through hole 43, and the extension plate 44, the stability, safety, flexibility, and adjustability of the telescopic mechanism 4 are achieved. To meet current usage needs, when the size of the smoke hood needs to be adjusted during use, bolt 47 can be loosened. At this time, the extension plate 44 slides within the displacement groove 41. By adjusting the position of the extension plate 44, the coverage area of ​​the smoke hood can be adjusted. After adjustment, the extension plate 44 is fixed with bolt 47. At this time, the limiting block 42 engages with the limiting groove 45, increasing the stability of the extension plate 44 within the displacement groove 41. The telescopic mechanism 4 allows the device to adjust the size of the smoke hood according to actual needs, increasing the practicality of the device. Additionally, when the smoke hood needs to be folded, rotating the rotating sleeve 33 rotates... Sleeve 33 rotates on the outer wall of screw 32. At this time, connecting rod 34 drives folding plate 36 to rotate through connecting bracket 35. While folding plate 36 rotates, it drives extension plate 310 to move. Extension plate 310 drives baffle 39 to move in mounting groove 37. At this time, spring 38 is deformed by force. When folding plate 36 rotates to the appropriate position, the reaction force of spring 38 pushes baffle 39. At this time, extension plate 310 limits folding plate 36, increasing the stability of folding plate 36 after folding. The flipping mechanism 3 makes it easy to fold the smoke hood, simplifies the folding steps, and improves the practicality of the device.

[0027] Working principle: First, a cover 2 is set on one side of the side plate 1. A flipping mechanism 3 is set on the inner top wall of the cover 2, and a telescopic mechanism 4 is firmly connected to the other side of the cover 2. In addition, an annular groove 5 is embedded and connected to the bottom of one side of the side plate 1. The upper end of the connecting frame 1 31 is firmly fixed to the inner top wall of the cover 2, and a screw 32 is set at the lower end. The other end of the screw 32 is equipped with a rotating sleeve 33. One end of the rotating sleeve 33 is connected to the connecting rod 34 by a rotating connection. The other end of the connecting rod 34 is also connected to the connecting frame 2 35 by a rotating connection. A folding plate 36 is firmly connected to one side of the connecting frame 2 35. The inner wall of the cover is embedded and connected to a mounting groove 37. A spring 38 is fixed to one side of the inner wall of the mounting groove 37, and a baffle 39 is fixed to one side of the spring 38. In addition, an extension plate 310 is fixed to the side of the two baffles 39 that are close to each other. Furthermore, the lower end of the connecting bracket 31 is connected to the upper end of the screw 32 by a rotating connection. The outer wall of the screw 32 is tightly connected to the inner wall of the rotating sleeve 33 by a threaded connection. The top of one side of the folding plate 36 is also connected to the top of one side of the side plate 1 by a rotating connection. One side of the cover 2 is firmly fixed to the top of one side of the side plate 1. Finally, the upper end of the flipping mechanism 3 is connected to the inner top wall of the cover 2 by a rotating connection to achieve flexible operation.

[0028] Then, the outer wall of the displacement groove 41 is tightly connected to the inner wall of the cover 2 through an embedded connection, ensuring the stability and reliability of the entire structure. A limiting block 42 is set on one side of the inner wall of the displacement groove 41. The function of this limiting block 42 is to limit the movement range of the extension plate 44 during the extension and contraction process, preventing damage caused by excessive extension and contraction. In addition, a through hole 43 is opened in the middle of one side of the displacement groove 41. The presence of this through hole 43 allows the bolt 47 to pass through the displacement groove 41. This design not only enhances the stability of the structure but also makes the assembly and disassembly of the entire telescopic mechanism 4 more convenient. A sliding connection is provided on the inner wall of the displacement groove 41. An extension plate 44 has limit grooves 45 extending through both sides. These limit grooves 45 match the outer diameter of the limit block 42, ensuring the stability and safety of the extension plate 44 during extension and retraction. An adjustment hole 46 is also provided in the middle of the inner wall of the extension plate 44. This adjustment hole 46 can adjust the extension length of the telescopic mechanism 4 according to actual needs, greatly improving the practicality and flexibility of the telescopic mechanism 4. Through the coordinated use of components such as the displacement groove 41, limit block 42, through hole 43, and extension plate 44, the telescopic mechanism 4 achieves stability, safety, flexibility, and adjustability, meeting current usage requirements. During use, when adjustment is needed... When adjusting the size of the fume hood, bolt 47 can be loosened, allowing the expansion plate 44 to slide within the displacement groove 41. Adjusting the position of the expansion plate 44 allows for adjustment of the fume hood's coverage area. After adjustment, the expansion plate 44 is fixed with bolt 47, at which point the limiting block 42 engages with the limiting groove 45, increasing the stability of the expansion plate 44 within the displacement groove 41. The telescopic mechanism 4 allows the device to adjust the size of the fume hood according to actual needs, increasing the device's practicality. Furthermore, when the fume hood needs to be folded, rotating sleeve 33 rotates, causing the screw 32 to rotate threaded on its outer wall. At this time, connecting rod 34 drives the folding plate via connecting bracket 35. When the folding plate 36 rotates, it drives the extension plate 310 to move. The extension plate 310 drives the baffle 39 to move within the mounting groove 37. At this time, the spring 38 is deformed by force. When the folding plate 36 rotates to the appropriate position, the reaction force of the spring 38 pushes the baffle 39. At this time, the extension plate 310 limits the folding plate 36, increasing the stability of the folding plate 36 after folding. The flipping mechanism 3 makes it easy to fold the smoke hood, simplifying the folding steps and improving the practicality of the device. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
