[0002] Mining air ducts are a type of ventilation equipment designed specifically for underground working environments such as mines and tunnels. Their main function is to provide fresh air, help reduce underground temperature and humidity, and improve the working environment. They can also be used to discharge harmful gases and dust generated during the operation, maintain air quality, and ensure the safety and health of miners. They play a vital role in the ventilation systems of mines, underground projects, and other enclosed spaces, ensuring a safe and comfortable working environment.

Therefore, it is necessary to propose an internal skeleton for mine ducts.

[0006] It should be noted that the above content falls within the technical knowledge of the inventor and does not necessarily constitute prior art. Utility Model Content

The inclined surface of the inclined surface rod 11 contacts the inclined surface of the inclined surface block 7 and squeezes the inclined surface block 7 to retract it and drive the limit plate 6 to move. When the limit plate 6 moves, it drives the pull rod 8 to move and squeezes the spring 9 to cause it to deform. After the inclined surface rod 11 completely enters the interior of the slot 10, the inclined surface block 7 is affected by the reaction force of the spring 9, rebounds and resets and is stuck in the inside of the card slot 12, so that the connecting end 4 outside the first corrugated air duct 1 and the mounting end 3 outside the second corrugated air duct 2 are quickly connected, so that the first corrugated air duct 1 and the second corrugated air duct 2 are connected, the pipeline length is increased, and the practicality is strong. By driving the inclined surface block 7 out of the inside of the card slot 12 by the pull ring 13, the first corrugated air duct 1 and the second corrugated air duct 2 can be separated, and the disassembly and assembly efficiency is high.

The disassembly and assembly efficiency is high, and the pipeline can be added or reduced according to the actual application scenario; the U-shaped rod 15 is fixed on the fixed rod The internal sliding of 14 realizes the telescopic effect. The height of the first corrugated air duct 1 and the second corrugated air duct 2 can be adjusted according to different usage conditions. Then, the fixing pin 17 is passed through the insertion hole 16 corresponding to the U-shaped rod 15 and the fixing rod 14, and the fixing pin 17 is fixed with the fastening nut 18, thereby fixing the telescopic distance of the U-shaped rod 15. The air duct can be quickly installed when used with the telescopic hanging basket 26, and the efficiency of putting into use is high. The first corrugated air duct 1 and the second corrugated air duct 2 are both corrugated, and the air duct with strong extension effect is easy to expand. To open and store, the handle 23 is used to drive the bidirectional screw 20 to rotate, and when the bidirectional screw 20 rotates, it drives the two sliders 21 to move, and when the two sliders 21 move, it drives the two splints 22 to move. Any fixed object is found in the mine tunnel, and the fixed object is clamped by the two splints 22, so that the wind tube has the effect of temporary and quick hanging, which is highly practical. When the slider 21 moves, it drives the limit block 24 to slide inside the limit groove 25. The limit block 24 and the limit groove 25 are used in conjunction to limit the splint 22, thereby improving the movement stability of the splint 22.
