[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 2 - 4As shown in the figure, an embodiment provided by the present utility model is an assembled silent ventilation duct, which includes a duct body 1. A main installation ring 2 is detachably connected to the left side of the outer wall of the duct body 1 for installing and connecting between two duct bodies 1. Both the front and rear parts on the right side of the outer wall of the duct body 1 are detachably connected with auxiliary installation rings 5. Fixed frames 6 are fixedly connected to the opposite ends of the auxiliary installation rings 5. On both sides of the inner wall of the fixed frame 6, there are pull rods 7 for limiting the pull rods 7 and for installing and disassembling the duct bodies 1. Installation blocks 3 fixedly connected to the upper and lower sides of the left end of the main installation ring 2. Card slots 4 are opened at both the front and rear ends of the installation blocks 3. Limit rods 9 are fixedly connected to both the front and rear ends of the fixed frame 6. Through holes 8 are opened on the outer walls of the pull rods 7. The shape of the limit rod 9 fits the through hole 8. Rotating rings 11 are rotatably connected to both the front and rear ends of the fixed frame 6. Torsion springs 10 are fixedly connected to the opposite ends of the rotating rings 11. The other ends of the torsion springs 10 are fixedly connected to the opposite sides of the outer wall of the pull rod 7. The inner walls of the rotating rings 11 are slidably connected to the outer wall of the pull rod 7. A clamping block 14 is slidably connected to the outer wall of the pull rod 7. Springs 13 are fixedly connected to the opposite sides of the inner wall of the clamping block 14. The other ends of the springs 13 are fixedly connected to the opposite ends of the pull rod 7. The shape of the clamping block 14 fits the card slot 4. The right ends of the clamping block 14 and the left ends of the front and rear sides of the installation block 3 are both arc surfaces. Pulling springs 12 are fixedly connected to the opposite ends of the clamping block 14. The other ends of the pulling springs 12 are fixedly connected to the opposite sides of the inner wall of the fixed frame 6.

[0027] Specifically, the shapes of the chute in the fixed frame 6 and the card slot 4 both fit the shape of the clamping block 14. Thus, when rotating the pull rod 7, the clamping block 14 will not rotate together. Secondly, after the disassembly or installation is completed, release the pull rod 7. The pull rod 7 is pulled back to its original position by the pulling spring 12. At the same time, the pull rod 7 is rotated back to its original position by the torsion spring 10. The limit rod 9 is inserted into the inner wall of the pull rod 7 to limit the pull rod 7. During installation, only need to install the main installation ring 2 and the auxiliary installation ring 5 on both sides of the outer wall of the duct body 1, and directly insert the installation block 3 into the fixed frame 6 to complete the installation between the duct bodies 1. The operation is simple, and the installation process is easy to implement, without the need for complex welding and cutting, avoiding additional costs caused by construction delays.

[0028] Refer to Figure 1 and Figure 5 As shown in the figure, the duct body 1 includes an outer layer 15, a middle layer 16 and an inner layer 17.

[0029] Specifically, the material of the inner layer 17 is galvanized steel sheet, the material of the middle layer 16 is glass fiber, and the material of the outer layer 15 is polyurethane. Through the multi-layer design, the duct can achieve multiple functions from noise control, heat insulation, mechanical protection, fire resistance improvement to environmental adaptability, not only improving the performance and reliability of the system, but also significantly reducing the comprehensive cost and the difficulty of long-term maintenance.

[0030] Working principle: During installation, first install the main installation ring 2 and the auxiliary installation ring 5 on both sides of the outer wall of the pipeline body 1 respectively. Secondly, align the installation block 3 on another pipeline body 1 with the fixing frame 6 and insert the installation block 3 into the fixing frame 6. When the installation block 3 contacts the clamping block 14, it drives the clamping block 14 to move to both sides. After the installation block 3 is installed in place, the spring 13 is used to snap the clamping block 14 into the card slot 4 to limit the installation block 3, and the installation can be completed. At the same time, when disassembly is required, first rotate the limit rod 9, align the limit rod 9 with the through hole 8, and then pull the pull rod 7 outward. The pull rod 7 drives the clamping block 14 to be taken out of the card slot 4, and the disassembly can be completed. Secondly, the smooth inner wall of the inner layer 17 can reduce the friction during the flow of air or liquid, which can ensure the rapid and smooth flow of the fluid, reduce the flow resistance. The middle layer 16 is mainly used to absorb noise and maintain the temperature. The outer layer 15 can enhance the durability and structural strength of the pipeline and prevent the entry of external noise.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
