[0024] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Reference Figures 1-3 An embodiment of this utility model provides: a mining ventilation fan inner cylinder, including a diffuser body 2, an inner diffuser cylinder 12 provided on the inner wall of the diffuser body 2, a connecting frame 13 fixedly connected to the inner wall of the inner diffuser cylinder 12, a connecting column 15 slidably connected to the inner wall of the connecting frame 13, a connecting cap 14 fixedly connected to the outer wall of the connecting column 15, the lower surface of the connecting cap 14 slidably connected to the outer wall of the connecting frame 13, an inspection door 16 fixedly connected to the outer wall of the connecting column 15, a handle 17 fixedly connected to the outer wall of the inspection door 16, a liner 18 provided on the outer wall of the inspection door 16, the outer wall of the liner 18 adhering to the inner wall of the inner diffuser cylinder 12, and a buckle assembly provided on the outer wall of the diffuser body 2 for fixing the air inlet box 1;

[0026] Specifically, first remove the liner 18, then pull the handle 17 in the opposite direction. The handle 17 is used to move the inspection door 16, which in turn moves the connecting column 15, which in turn moves the connecting cap 14. This allows the inspection door 16 to be opened quickly, making it easier for maintenance personnel to enter the diffuser inner cylinder 12 for maintenance.

[0027] Reference Figure 1 and Figure 4 The snap-fit ​​assembly includes a fixing post 9, the outer wall of which is fixedly connected to the outer wall of the diffuser body 2, and a sliding block 10 slidably connected to the outer wall of the fixing post 9; a fixing block 11 is fixedly connected to the outer wall of the fixing post 9, and a stop block 8 is provided on the outer wall of the fixing post 9; the outer wall of the stop block 8 is slidably connected to the outer wall of the sliding block 10, and the outer wall of the stop block 8 is slidably connected to the outer wall of the fixing post 9; a sliding post 5 is fixedly connected to the outer wall of the stop block 8, and a spring 7 is provided on the outer wall of the sliding post 5.

[0028] Specifically, the fixed block 11 is used to prevent the sliding block 10 from sliding, and the stop block 8 is used to drive the sliding block 10 to slide.

[0029] Reference Figure 4 and Figure 5 The outer wall of the sliding column 5 is slidably connected to the connecting plate 4, and the outer wall of the connecting plate 4 is fixedly connected to the air inlet box 1; the outer wall of the spring 7 is set on the outer wall of the stop block 8, and the outer wall of the spring 7 is set on the outer wall of the connecting plate 4; the inner wall of the air inlet box 1 is provided with a dustproof net 3, and the outer wall of the sliding column 5 is fixedly connected to the baffle 6.

[0030] Specifically, the sliding column 5 slides to drive the stop block 8 to compress the spring 7, thereby achieving quick disassembly of the air intake box 1, which greatly reduces the time cost required for later maintenance or replacement of the dust filter 3.

[0031] Working principle: When the equipment needs to be used, first remove the bolts on the surface of the liner 18 to remove the liner 18. Pull the handle 17, which will move the outer wall inspection door 16. When the inspection door 16 moves, it will move the inner wall connecting column 15. When the connecting column 15 moves, it will move the outer wall connecting cap 14, thus achieving the effect of quickly opening the inspection door 16. Push the air intake box 1, which will move the outer wall connecting plate 4. When the connecting plate 4 moves, it will move the sliding column 5 on the inner wall of the connecting plate 4. When the sliding column 5 slides, it will cause the stop block 8 to move on the outer wall of the sliding block 10. When the sliding column 5 slides, it will cause the stop block 8 to compress the spring 7, thereby achieving the effect of quickly disassembling the air intake box 1, which facilitates the later maintenance and replacement of the dust screen 3. Finally, this equipment can not only make it easier for maintenance personnel to enter the diffuser inner cylinder 12 for work through the inspection door 16, but also quickly disassemble the air intake box 1 through the sliding of the stop block 8, thereby reducing the time cost required for later maintenance and replacement of the dust screen 3 and improving work efficiency.
