[0020] The present utility model provides a fiber fabric heat-insulating air duct, which includes an inner base layer 101, an outer protective layer 102, a docking assembly, a pull ring 103, a heat-insulating layer 104, a sealing ring 105, a slide rail 106 and a slider 107. The docking assembly includes a fixing ring 108, a fixing shell 109, a plug rod 110, a circular ring 111, a return spring 112 and a threaded ring 113. The fixing ring 108 is provided with a plurality of jacks 114. The right inner wall of the inner base layer 101 has thread patterns 115. The left end of the plug rod 110 has an inclined section 116.

[0021] For this specific embodiment, the threaded ring 113 of the current device is rotationally adapted to the thread patterns 115 of the next device, and at the same time, the plug rod 110 of the current device is pulled, so that the two devices are successfully docked. After the docking is completed, the plug rod 110 of the current device is released. Under the elastic force of the return spring 112, the current plug rod 110 is inserted into the jack 114 of the next device, thereby fixing the two devices, so that the threaded ring 113 and the thread patterns 115 will not loosen. Therefore, after the devices are spliced, the devices can be prevented from loosening, and further the air leakage phenomenon can be avoided, reducing the energy loss. The inner base layer 101 is made of high-quality materials such as high-strength polyester fiber, and has good air permeability and uniform air supply. The outer protective layer 102 is made of PVC coating material, providing protection and enhancing the durability of the air duct.

[0022] Among them, the outer protective layer 102 is fixedly sleeved outside the inner base layer 101. The threaded ring 113 is fixedly connected to the inner wall of the inner base layer 101 and is located at the left end of the inner base layer 101. The threaded ring 113 is adapted to the thread pattern 115. The fixing ring 108 is fixedly sleeved outside the outer protective layer 102 and is located at the right end of the outer protective layer 102. The fixing shell 109 is fixedly connected to the upper left end of the outer protective layer 102. One end of the insertion rod 110 penetrates through the fixing shell 109. The circular ring 111 is fixedly sleeved outside the insertion rod 110 and is located inside the fixing shell 109. Both ends of the return spring 112 are fixedly connected to the circular ring 111 and the inner wall of the fixing shell 109 respectively. Rotate and adapt the threaded ring 113 of the current device to the thread pattern 115 of the next device, and at the same time pull the insertion rod 110 of the current device, so that the two devices can be successfully docked. After the docking is completed, release the insertion rod 110 of the current device. Under the elastic force of the return spring 112, the current insertion rod 110 is inserted into the insertion hole 114 of the next device, thereby fixing the two devices and preventing the threaded ring 113 and the thread pattern 115 from loosening. Therefore, after the device is spliced, the device can be prevented from loosening, and further the air leakage phenomenon can be avoided, reducing the energy loss. The inner base layer 101 is made of high-quality materials such as high-strength polyester fiber, and has good air permeability and uniform air supply. The outer protective layer 102 is made of PVC coating material, providing protection and enhancing the durability of the air duct.

[0023] Secondly, the left end of the insertion rod 110 has an inclined plane 116, and the pull ring 103 is fixedly connected to the right end of the insertion rod 110. Through the setting of the pull ring 103, it is convenient for the staff to pull the insertion rod 110 to move when replacing and disassembling the device, improving the convenience. Through the setting of the inclined plane 116, when splicing, there is no need to pull the insertion rod 110 to move anymore. Just squeeze the inclined plane 116 with the insertion hole 114, and then push the insertion rod 110 to move. Under the elastic force of the return spring 112, the insertion rod 110 is finally adapted to the corresponding insertion hole 114, thus reducing the operation steps of the staff.

[0024] At the same time, the heat insulation layer 104 is arranged between the outer protective layer 102 and the inner base layer 101. By using glass fiber material for the heat insulation layer 104, it is ensured that the air duct can effectively reduce energy loss when transporting hot and cold air.

[0025] In addition, the sealing ring 105 is fixedly connected to the inner base layer 101 and is located at the left end of the inner base layer 101. The sealing ring 105 improves the sealing effect after the device is spliced and prevents air flow from leaking out through the splicing gap.

[0026] Moreover, the slide rail 106 is fixedly connected to the inner wall of the fixed housing 109. One end of the slider 107 is slidably adapted to the slide rail 106, and the other end of the slider 107 is fixedly connected to the insertion rod 110. Through the arrangement of the slide rail 106 and the slider 107, the insertion rod 110 is made more stable during movement, reducing the shaking during its movement.

[0027] When using the fiber fabric thermal insulation air duct of the present utility model, the thread ring 113 of the current device is rotationally adapted to the thread pattern 115 of the next device, and at the same time, the insertion rod 110 of the current device is pulled, so that the two devices are successfully docked. After the docking is completed, the insertion rod 110 of the current device is released. Under the elastic force of the return spring 112, the current insertion rod 110 is inserted into the insertion hole 114 of the next device, thereby fixing the two devices and preventing the thread ring 113 from loosening from the thread pattern 115. Thus, after the devices are spliced, the situation of loosening of the devices is avoided, and further the air leakage phenomenon is avoided, reducing the energy loss. The inner base layer 101 is made of high-quality materials such as high-strength polyester fiber, having good air permeability and uniform air supply. The outer protective layer 102 is made of PVC coating material, providing protection and enhancing the durability of the air duct. Through the arrangement of the pull ring 103, it is convenient for the staff to pull the insertion rod 110 to move when replacing and disassembling the device, improving the convenience. Through the arrangement of the inclined plane 116, during splicing, there is no need to pull the insertion rod 110 to move. Only by squeezing the inclined plane 116 with the insertion hole 114, the insertion rod 110 is pushed to move, and under the elastic force of the return spring 112, the insertion rod 110 is finally adapted to the corresponding insertion hole 114, thereby reducing the operation steps of the staff. Through the thermal insulation layer 104 made of glass fiber material, it is ensured that the air duct can effectively reduce energy loss when conveying hot and cold air. The sealing ring 105 improves the sealing effect after the splicing of the devices, preventing air flow from leaking out through the splicing gap. Through the arrangement of the slide rail 106 and the slider 107, the insertion rod 110 is made more stable during movement, reducing the shaking during its movement.
