Description

Technical Field

[0001] This application relates to the field of building equipment engineering, and in particular to a heating and ventilation duct with a shock-absorbing and buffering structure. Background Technology

[0002] In modern buildings, HVAC ducts serve as crucial channels for air transport, widely used in air conditioning, ventilation, and smoke extraction systems in various civil and industrial buildings. However, the operation of equipment such as fans and air handling units generates high-frequency mechanical vibrations and airflow disturbances. If these vibrations are directly transmitted to the duct body, they not only cause noise pollution from the duct system, interfering with the normal use of the surrounding environment, but also lead to fatigue stress in the duct's metal materials due to long-term vibration, accelerating duct deformation and cracking, reducing system lifespan, and even affecting the efficiency of air conditioning and the safety of fire-fighting smoke extraction systems. Therefore, to reduce the adverse effects of vibration on HVAC duct systems, it is essential to develop an HVAC duct with a vibration-damping and buffering structure. In existing technologies, vibration damping measures for HVAC ducts mostly employ simple rigid supports or single spring dampers. Rigid supports fix the ducts to the building structure using brackets, relying on the strength of the brackets to limit the displacement of the ducts. The technical principle is to use the rigidity of the metal brackets to resist vibration transmission, and to reduce duct swaying by increasing the stiffness of the connection points. Single spring dampers, on the other hand, install springs between the duct and the brackets, using the elastic deformation of the springs to absorb some of the vibration energy. The expansion and contraction of the springs buffer the vibration of the ducts, thereby reducing the transmission of vibration to the supporting structure. However, neither rigid supports nor single spring dampers can effectively block the transmission of vibration between the duct body and the surrounding structure. This causes the vibration of the duct body to be easily transmitted to the surrounding building structure, resulting in noise pollution and structural fatigue of the duct system, affecting the stable operation and service life of the system. Therefore, a heating and ventilation duct with a shock-absorbing and buffering structure is proposed to solve the above problems. Utility Model Content

[0005] In summary, this application includes at least one of the following beneficial technical effects: 1. In this utility model, when the duct body vibrates, the vibration is transmitted to the buffer assembly through the fixed frame. The shock-absorbing pad absorbs part of the energy, reducing rigid transmission. The damper consumes energy to suppress vibration. The displacement of the connecting frame drives the connecting rod to slide in the sleeve, causing the first spring to deform. Through elastic extension and contraction, the energy is absorbed and released. The connecting rod rotates to adapt to the angle change, realizing vibration buffering. This solves the problem of noise and structural fatigue caused by the easy transmission of duct body vibration to the surrounding structure. The above technical solution improves the vibration reduction effect and stability of the duct system.

A fixing frame 4 is provided on the side wall of the duct body 1. A rubber pad 5 is fixedly connected to the side wall of the fixing frame 4. The rubber pad 5 is used to increase the friction between the fixing frame 4 and the duct body 1 and to buffer vibration, thereby preventing the fixing frame 4 from sliding and reducing vibration transmission. The side wall of the rubber pad 5 is in contact with the side wall of the duct body 1. The damper 6 is fixedly installed between the shock absorber 3 and the fixed frame 4, and the side wall of the shock absorber 3 and the fixed frame 4 is fixedly connected to the connecting frame 7. The side wall of the shock-absorbing pad 3 is provided with a sleeve 8. A pair of connecting rods 9 are slidably connected inside the sleeve 8. The connecting rods 9 are used to transmit force and adapt to the position changes caused by vibration, thereby transmitting the force on the connecting frame 7 to the first spring 10. One side of the connecting rod 9 is rotatably connected inside the connecting frame 7. The connecting rod 9, together with the sleeve 8 and the first spring 10, slides and extends, achieving the effect of absorbing vibration energy and buffering shock absorption. The sleeve 8 is equipped with a first spring 10, which is used to absorb and release vibration energy, thereby reducing the vibration of the duct body 1 through elastic deformation buffering and shock absorption. The side wall of the first spring 10 is fixedly connected to the connecting rods 9. Reference Figures 4-5 The fixing component includes a fixing ring 11 and a fixing ring 12. The fixing ring 11 and the fixing ring 12 are used to clamp and fix the connection part of the air duct body 1, thereby realizing a stable connection between the two sections of air duct. The fixing ring 11 and the fixing ring 12 are internally slidably connected to the side wall of the air duct body 1. A rubber pad 13 is fixedly connected inside the fixing ring 11 and the fixing ring 12. The rubber pad 13 is used to enhance the sealing between the fixing ring and the air duct body 1 and reduce vibration transmission. The side wall of the rubber pad 13 is in contact with the side wall of the air duct body 1. A pair of fixing blocks 14 are fixedly connected to the side wall of fixing ring 11. The fixing blocks 14 are used to cooperate with the mounting frame 16 to achieve the initial positioning and connection of fixing ring 11 and fixing ring 2 12. Fixing holes 15 are provided inside the fixing blocks 14. A pair of mounting frames 16 are fixedly connected to the side wall of the second fixing ring 12. The side wall of the fixing block 14 is slidably connected inside the mounting frame 16. A locking block 17 is slidably connected inside the mounting frame 16. The locking block 17 is used to lock into the fixing hole 15, thereby realizing the locking and fixing of the fixing block 14 and the mounting frame 16, completing the initial connection between the first fixing ring 11 and the second fixing ring 12. The side wall of the locking block 17 is slidably connected inside the fixing hole 15. The side wall of the card block 17 is fixedly connected to the limiting block 18, and the side wall of the limiting block 18 is slidably connected inside the mounting frame 16; A second spring 19 is fixedly connected to the side wall of the limiting block 18. The second spring 19 is used to push the locking block 17 into the fixing hole 15. The side wall of the second spring 19 is fixedly connected to the inside of the mounting frame 16. The fixing block 14 and the mounting frame 16 are internally threaded with screws 20. The screws 20 are used to further tighten the fixing block 14 and the mounting frame 16, thereby enhancing the stability of the connection between the fixing ring 11 and the fixing ring 12. The side wall of the screw 20 is fitted with a rubber ring 21. The rubber ring 21 is used to reduce the rigid contact between the screw 20 and the mounting frame 16, thereby reducing the risk of the screw 20 loosening due to vibration. The side wall of the rubber ring 21 fits against the side wall of the mounting frame 16. The screw 20 has a nut 22 threadedly connected to its side wall. The nut 22 is used to cooperate with the screw 20 to enhance the fastening effect, thereby further ensuring the stability of the connection between the fixing block 14 and the mounting frame 16. The nut 22 has a rubber pad 23 fixedly connected to its side wall. The side wall of the rubber pad 23 fits against the side wall of the mounting frame 16. The rubber pad 23 is used to form a buffer between the nut 22 and the mounting frame 16, thereby reducing the impact of vibration on the nut 22 and preventing the nut 22 from loosening.

[0010] Working principle: When the duct body 1 vibrates, the vibration is transmitted to the buffer assembly through the fixed frame 4. The shock-absorbing pad 3 first absorbs part of the vibration energy, reducing the rigid vibration transmission between the mounting plate 2 and the fixed frame 4. The damper 6 consumes the vibration energy through the friction and deformation of the internal damping material, further suppressing the vibration amplitude. At the same time, the connecting frame 7 moves with the vibration, causing the connecting rod 9 to slide in the sleeve 8, causing the first spring 10 to deform. The vibration energy is absorbed and released through elastic extension and contraction. The rotation of the connecting rod 9 adapts to the angle change caused by the vibration, ultimately achieving the buffering of the vibration of the duct body 1. When fixing the two sections of the duct body 1, the fixing ring 11 and the fixing ring 22 are put on the connection part of the duct body 1. The rubber pad 23 is attached to the side wall of the duct body 1 to enhance the sealing and shock absorption effect. The fixing ring 11 and the fixing ring 22 are pushed closer to each other, so that the fixing block 14 slides into the mounting frame 16. The second spring 19 pushes the limiting block 18 and the locking block 17 to move. The locking block 17 is locked into the fixing hole 15 to achieve initial fixation. Then, the screw 20 is passed through the fixing block 14 and the mounting frame 16. After the rubber ring 21 is put on, the nut 22 is tightened. The rubber pad 3 23 forms a buffer between the nut 22 and the mounting frame 16 to prevent loosening, thereby completing the connection of the two sections of the duct body 1.
