[0002] Ventilation is an important sanitation technology for controlling indoor dust, harmful gases or vapors and improving the indoor microclimate. Its main function is to discharge the polluted air indoors and introduce clean air from the outside, which can ensure a good indoor environment for a long time. Among them, ventilation ducts are essential components of ventilation equipment.

[0003] The patent with the patent number CN218028728U discloses a seamless docking and splicing mechanism for mechanical air ducts. Through the mutual cooperation of a clamping groove, an installation groove, a limiting plate, a return spring and a clamping block, a clamping structure is formed between the air duct body and the docking pipe, and then the two air duct bodies are spliced, making the installation and disassembly of the mechanical air duct time-saving and labor-saving.

[0004] However, when disassembling the air duct body and the docking pipe in the above solution, the return spring is prone to jamming, resulting in difficult disassembly. Moreover, using a spring to clamp the limiting plate in the clamping groove, the structure is unstable, causing shaking between the air duct body and the docking pipe, resulting in poor sealing between the air duct body and the docking pipe and easy gas leakage. Therefore, there is an urgent need for a new type of spliced smoke exhaust air duct to solve the above problems. Summary of the Utility Model

[0005] To solve the above existing problems, the utility model provides a spliced smoke exhaust air duct that fixes one end of the air duct body in the docking pipe through a clamping component, enhancing the stability and sealing performance between the air duct body and the docking pipe, with convenient operation and stable structure.

[0006] The technical solution adopted by the utility model is as follows: The spliced smoke exhaust air duct of the utility model includes an air duct body, a docking pipe, a clamping groove and a clamping component. The air duct bodies are symmetrically arranged on both sides of the docking pipe. The clamping grooves are symmetrically arranged at both ends of the docking pipe. One end of the air duct body is arranged in the clamping groove. The clamping component is arranged in the docking pipe. The clamping component includes a clamping plate, a clamping screw rod and a guide rod. There are two clamping plates, and the two clamping plates are symmetrically arranged inside both ends of the docking pipe. The clamping screw rod is rotatably arranged in the docking pipe. The clamping screw rod is threadedly connected to the two clamping plates. The guide rod is arranged in the docking pipe. There are two guide rods, and the two guide rods are symmetrically arranged on both sides of the clamping screw rod. The guide rod penetrates through the clamping plate.

[0007] Further, left threads and right threads are respectively arranged at both ends of the clamping screw rod, and the left thread and the right thread are respectively threadedly connected to the two clamping plates.

[0008] Further, one end of the clamping screw penetrates through the side wall of the docking pipe. A clamping knob is fixedly arranged at one end of the clamping screw, and the clamping knob is rotatably arranged outside the docking pipe.

[0009] Further, fixed card slots are arranged on the side wall of the clamping plate. The fixed card slots are symmetrically arranged at both ends of the clamping plate and penetrate through the clamping plate.

[0010] Further, fixed clamping blocks are fixedly arranged on the inner side wall of the air duct body. The fixed clamping blocks are arranged on one side of the clamping plate and are symmetrically arranged at both ends of the air duct body. The fixed clamping blocks are clamped and arranged in the fixed card slots.

[0011] Further, a limiting plate is arranged on one side of the clamping plate away from the side wall of the air duct body. The limiting plate is fixedly connected to the air duct body, and the clamping screw and the guiding rod penetrate through the limiting plate.

[0012] With the above structure, the beneficial effects obtained by the present utility model are as follows: For the spliced smoke exhaust air duct proposed in this solution, the two air duct bodies to be docked are respectively clamped in the clamping grooves at both ends of the docking pipe, and then the clamping assembly is used to fix one end of the air duct body in the docking pipe. Rotate the clamping screw, so that the rotating clamping screw drives the clamping plate to linearly move along the guiding rod.

[0019] As Figures 1 to 4 shown, the spliced smoke exhaust air duct proposed by this solution includes an air duct body 1, a docking pipe 2, a clamping groove 3 and a clamping assembly 4. The air duct body 1 is symmetrically arranged on both sides of the docking pipe 2. The clamping grooves 3 are symmetrically arranged at both ends of the docking pipe 2. One end of the air duct body 1 is arranged in the clamping groove 3. The clamping assembly 4 is arranged in the docking pipe 2. The clamping assembly 4 includes a clamping plate 5, a clamping screw 6 and a guide rod 7. There are two clamping plates 5, and the two clamping plates 5 are symmetrically arranged at both ends inside the docking pipe 2. The clamping screw 6 is rotatably arranged in the docking pipe 2. The clamping screw 6 is threadedly connected to the two clamping plates 5. The guide rod 7 is arranged in the docking pipe 2. There are two guide rods 7, and the two guide rods 7 are symmetrically arranged on both sides of the clamping screw 6. The guide rod 7 penetrates through the clamping plate 5.

[0020] As Figure 2 and Figure 3 shown, the two ends of the clamping screw 6 are respectively provided with a left thread 8 and a right thread 9. The left thread 8 and the right thread 9 are respectively threadedly connected to the two clamping plates 5. One end of the clamping screw 6 penetrates through the side wall of the docking pipe 2. A clamping knob 10 is fixedly arranged at one end of the clamping screw 6. The clamping knob 10 is rotatably arranged outside the docking pipe 2. A limiting plate 13 is arranged on the side of the clamping plate 5 away from the side wall of the air duct body 1. The limiting plate 13 is fixedly connected to the air duct body 1. The clamping screw 6 and the guide rod 7 penetrate through the limiting plate 13.

[0021] As Figure 2 and Figure 4 shown, the side wall of the clamping plate 5 is provided with fixed card slots 11. The fixed card slots 11 are symmetrically arranged at both ends of the clamping plate 5. The fixed card slots 11 penetrate through the clamping plate 5.
