The application scope of HVAC pipes is very wide, generally including purification system return air ducts, central air-conditioning ventilation ducts, industrial supply and exhaust ventilation ducts, environmental protection system suction and exhaust ducts, mining gas extraction pipes and mining rubberized cloth air ducts, etc. When using HVAC pipes, liquid or air flow will pass through the HVAC pipes. During the flow of liquid or gas, the HVAC pipes will vibrate, which will cause damage to the HVAC pipes and walls, thereby shortening the service life of the HVAC pipes. The vibration will also generate noise that affects the surrounding environment, so HVAC pipe shock-absorbing and noise-reducing devices are usually used to reduce the shock and noise of the HVAC pipes.

HVAC needs to cooperate with ventilation pipes to complete the work of heating, ventilation and air conditioning. The existing technical solutions have the following shortcomings: when the wind flows through the ventilation duct, the flow rate is fast, which will form resonance. In severe cases, the entire duct will vibrate violently, generate loud noise, and even vibrate and collide with the ceiling of the building, affecting the normal work and rest of people in the building.

[0025] The connection assembly between the hanging frame 2 and the tube body 1 can buffer the vibration of the tube body 1. The fixing ring 3 fixes the tube body 1, and then several tension springs 4 pull the fixing ring 3 from all directions and connect it to the sliding component on the hanging frame 2. The sliding component includes a slider 5 connected to the tension spring 4, and several compression springs 6 whose sides are connected to the inner wall of the hanging frame 2. The tension spring 4 is fixedly connected to the side of the slider 5 close to the fixing ring 3. The inner wall of the hanging frame 2 is provided with a limiting slide groove 7 corresponding to the slider 5. The slider 5 is installed in the limiting slide groove 7. There are four limiting slide grooves 7, which are respectively opened in the middle of the inner side of the four walls of the hanging frame 2; one end of the compression spring 6 is connected to the side of the slider 5, and the other end is connected to the side wall of the limiting slide groove 7. The tension spring 4 can buffer and reduce shock to the tube body 1 in the longitudinal direction, the slider 5 of the sliding component can move horizontally in the limiting slide groove 7, and compression springs 6 are provided in each direction of the slider 5. Each compression spring 6 can generate horizontal resistance to the movement of the slider 5, thereby buffering the vibration brought by the tension spring 4 in the lateral direction, thereby ensuring that the impact of the vibration of the tube body 1 on the outside is greatly reduced and does not interfere with the work and rest of nearby personnel.
[0026] The hoisting frame 2 is a square pipe with four sides sealed, which is sleeved on the outside of the pipe body 1, and the sound insulation layer 9 completely covers the outside of the square pipe; the limit slide 7 is a cylindrical cavity, the slider 5 is a cylindrical structure with a size smaller than the cavity of the limit slide 7, and the compression spring 6 is evenly distributed around the slider 5 and in the gap between the limit slide 7. The upper edge of the limit slide 7 is provided with an opening for the tension spring 4 to pass through, and the opening area is smaller than the cross-sectional area of the slider 5 and larger than the annular area of the tension spring 4.
[0027] The hoisting frame 2 is also provided with a limiting ring 8 for limiting the pipe body 1. The limiting ring 8 is installed on the inner wall of the hoisting frame 2 through a limiting bracket 10. The inner diameter of the limiting ring 8 is larger than the inner diameter of the fixing ring 3 and smaller than the minimum inner diameter of the hoisting frame 2.

There are multiple limiting rings 8 and they are evenly distributed along the length direction of the pipe body 1 and are spaced apart from the connecting components. A layer of buffer pad 11 is provided on the inner wall of the limiting ring 8. When the pipe body 1 is disturbed by some external force and the vibration amplitude is too large, the traction force of the tension spring 4 on the pipe body 1 cannot be fully supported, and the tension spring 4 may break, or even the pipe body 1 and the external frame may collide and rupture and leak.

[0029] The connection assembly between the hanging frame 2 and the pipe body 1 can buffer the vibration of the pipe body 1.

One end of the compression spring 6 is connected to the side of the slider 5, and the other end is connected to the side wall of the limiting slide 7. The tension spring 4 can buffer and reduce shock to the pipe body 1 in the longitudinal direction. The slider 5 of the sliding component can move horizontally in the limiting slide 7. The slider 5 is provided with compression springs 6 in all directions. Each compression spring 6 can generate horizontal resistance to the movement of the slider 5, thereby buffering the vibration caused by the tension spring 4 in the lateral direction, thereby ensuring that the impact of the vibration of the pipe body 1 on the outside is greatly reduced and does not interfere with the work and rest of nearby personnel.
[0030] The sound insulation layer 9 is attached to the inner wall of the circular pipe and has a hole at the position of the limiting slide groove 7; the sound insulation layer 9 is made of a flexible sound-absorbing sponge material, which can absorb sound and provide buffering; when the pipe body 1 is disturbed by some external force and the vibration amplitude is too large, the traction force of the tension spring 4 on the pipe body 1 cannot be fully supported, and the tension spring 4 may break, or even the pipe body 1 and the external frame may collide and rupture and leak. At this time, the sound insulation layer 9 can buffer and limit the pipe body 1, so that its vibration amplitude is within a reasonable range, thereby protecting the pipe body 1, the tension spring 4 and the lifting frame 2.
[0031] There are four limit slide grooves 7, which are evenly arranged around the inner wall of the pipe of the hanging frame 2. The sliding component includes a slider 5 connected to a tension spring 4, and several compression springs 6 whose sides are connected to the inner wall of the hanging frame 2. The tension spring 4 is fixedly connected to the top surface of the slider 5. The inner wall of the hanging frame 2 is provided with a limit slide groove 7 corresponding to the slider 5. The slider 5 is installed in the limit slide groove 7. One end of the compression spring 6 is connected to the side of the slider 5, and the other end is connected to the side wall of the limit slide groove 7. Each compression spring 6 can generate horizontal resistance to the movement of the slider 5, thereby buffering the vibration caused by the tension spring 4 from the lateral direction.
[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
